The MAX links a Local Area Network (LAN) to a Wide Area Network (WAN). The LAN
might comprise a few workstations, a large n umber of workstations and servers, or any number
of interconnected networks. WAN connections provid e lin ks between the LAN and virtually
any site or network.

The MAX provides multiple interfaces for your use in implementing your configuration.
Considerations for development of your WAN configuration include the number of remote
users who need access to your LAN, the types of telecommunications lines and services your
carrier can provide, and the spec ific MAX mo del y ou hav e p urch ased. WAN connections hav e
traditionally been either physically dedicated (nailed) from end to end or dial-up (switched).
Frame Relay, which provides the benefits of nailed connections but with greater flexibility, is
becoming increasingly popular. X.25 networks are predominant in Europe.

Although the MAX has a large number of features, you might only have to configure a few of
them, depending on what you want the MAX to do. Almost all applications require
configuration of IP routing. You can use R outin g In formation Protocol (RIP) or the newer

Open Shortest Path First (OSPF) protocol, which addresses many of RIP’s limitations. If you
have Novell Netware clients and servers, you can configure the MAX for Internetwork Packet

Introduction

eXchange (IPX) routing. Similarly, you can configure it for AppleTalk routing. If you need to
use a protocol that cannot be routed, the MAX supports transparent bridging as an alternative.

If you need to send data-intensive information to multiple users simultaneously, you can
significantly reduce traffic flow by setting up your network to support multicast forwarding. If
you have many remote clients who need secure connections to the home network, a tunneling
protocol, such as ATMP, PPTP, or L2TP, can provide virtual private connections over a public
network.

Y o u can define filters to cu stomize the way the MAX handles individua l packets of data. If yo u
do not implement dynamic filtering by means of a firewall such as an Ascend SecureConnect
firewall, you should probably define a filter on the MAX to provide rudimentary security. You
can also define filters to prevent unnecessary connections and to clear idle connections.

A MAX unit typically serves as a hub for numerous connections to a network. Configuration
should therefore be well planned. The parameters you need to set are organized in groups
referred to as profiles.

Using the MAX as an ISP or telecommuting hub

A MAX unit is a high-performance WAN router that concentrates many incoming connections
onto a corporate backbone or another network, such as the Internet or a Frame Relay network.
The connections are usually switched, but the MAX also supports leased connections fo r those
users whose connection times justify a permanent virtual connection to the backbone network.

2

A switched connection is a temporary link between devices, established only for the duration
of a call. When you use bandwidth-on-demand, the MAX adds and subtracts bandwidth as
necessary, keeping connection costs as low as possible.

The MAX most commonly serves as an Internet Service Provider (ISP) hub, managing many
switched IP connections to the Internet, or as a telecommuting hub, providing high-speed
connections between a corporate backbone and remote locations. MAX configuration options
provide the flexibility you need to optimize your installation. Management features include a
comprehensive set of control and monitoring functions and easy upgrades.

Using the MAX as an ISP hub

Individuals subscribe to an Internet Service Provider to get a TCP/IP connection to the
Internet. Subscribers dial in to a local Point-of-Presence (POP), typically by means of an
analog modem, an ISDN V.120 Terminal Adapter, or an ISDN router such as a Lucent
Pipeline. If you use the MAX as an ISP hub, configure it as an I P router, because it establishes
the dial-in WAN connection with subscribers and routes their data streams to other Internet
routers.

MAX 6000/3000 Network Configuration Guide 2-1

Configuration Concepts and Profiles

Using the MAX as an ISP or telecommuting hub

Figure 2-1 shows a typical ISP configuration with three POPs. Each POP has at least one MAX
on an Ethernet LAN that also includes another Internet router, which could be, for example, a
Lucent GRF 400 router.

Figure 2-1. Using the MAX as an ISP hub

Typically, the MAX has T1 or E1 lines that use ISDN signaling to connect to the WAN and
handle the incoming switched connections. To connect to Internet routers, the MAX most often
uses the local Ethernet network, but the connections between Internet routers can be any high
bandwidth connection, such as Frame Relay, nailed T1, nailed E1, HSSI, FDDI, or Sonet.
Large ISPs often support redundant MAX units and Internet routers on each Ethernet segment.

Using the MAX as a telecommuting hub

T elecommuters ar e typically at br anch of fices, at home, at customer sites, at vend or sites, or on
the road. The MAX enables these remote users to access th e corpor ate backbone jus t as though
they were connected locally. The backbone might be a NetWare LAN, an IP network, or a
multiprotocol network. Figure 2-2 shows an example in which home users, remote offices, and
customer sites can access the backbone network.

In this sample network, a telecommuter in a home office uses a Pipelin e 25 and Frame Relay to
log in to the corporate LAN. Users on a remote office LAN access the backbone through a
Pipeline 400 with a Switched-56 connection. A customer can access selected corporate
network resources by means of a Pipeline 50 with an ISDN BRI connection. A mobile user
with an analog modem can dial in to the backbone, provided that the MAX has a digital
modem card installed.

Notice that each user can access the MAX through a different type of line. While one user
might access the MAX by using the switched services on an ISDN BRI or Switched-56 line,
another might require a nailed 56K Frame Relay circuit.

Overview of MAX configuration

Before you configure the MAX, you should create a network diagram. Configuration tasks
generally consist of:

• Configuring the lines, channels, and ports, and how calls are routed between them

• Configuring Wide Area Network (WAN) connections and security

• Configuring the MAX as a Frame Relay or X.25 concentrator

• Configuring routing and bridging across the WAN

• Configuring Internet services, such as multicast, OSPF, and Virtual Private Networks
(VPNs)

MAX 6000/3000 Network Configuration Guide 2-3

Configuration Concepts and Profiles

Overview of MAX configuration

Creating a network diagram

Lucent strongly recommends that, after you have read these introductory sections, you diagram
your network and refer to the diagram while configuring the MAX unit. Creating a
comprehensive network diagram hel ps prevent problems durin g inst allatio n and co nfigurat ion,
and can help in troubleshooting any problems later.

Configuring lines, slots, and ports for WAN access

The MAX unit has four built-in T1 or E1 lines and a V.35 serial port (8 Mbps). Each T1 or E1
line has a wide variety of configuration options, including whether or not you use ISDN
signaling, the type of physical-layer framing, cable length, and telco options. The way you
configure each line affects how much bandwidth will be available and whether you can direct
outbound calls to use specific channels. The way you configure channels depends on your
connectivity needs.

Use the serial WAN port for a leased high-speed connection to a Frame Relay switch or to
another WAN router. The port itself requires little configuration. A Frame Relay or Connection
profile specifies most of the required information.

You can add expansion modules to support additional bandwidth (BRI lines), serial host por t
modules to support videoconferencing, and digital modems to support analog modem
connections over digital lines. The lines and ports on the modules (cards) have their own
configuration requirements, including the assignment of telephone numbers and information
about routing calls.

Once you enable the lines, slots, and ports for WAN access, you need to configure the way in
which outbound calls are routed to them (for dial-ou t access to the WAN) and the way in which
inbound calls are routed from them to other destinations (such as the local network).

Configuring WAN connections and security

When the MAX receives packets that require establishment of a particular WAN connection, it
automatically dials the connection. Software at both ends of the connection encapsulates each
packet before sending it out over the telephone lines. Each type of encapsulation supports its
own set of options, which can be configured on a per-connection basis to enable the MAX to
interact with a wide range of software and devices.

After a connection’s link encapsulation method has been negotiated , the MAX typically uses a
password to authenticate the call. For detailed information about authentication and
authorization, see the MAX Security Supp lement. Following are some of the connection
security features the MAX supports:

You can restrict who can access the MAX, by verifying the caller-ID

You can off load the authentication responsibility to a RADIUS o r

The MAX supports hand-held personal security cards, such as those
provided by Enigma Logic and Security Dynamics. These cards
provide users with a password that changes frequently, usually many
times a day. Support for dynamic passwords requires the use of a
RADIUS server that has access to an authentication server, such as an

authentication server.

services. Within the terminal server, you can restrict commands that

network security.

Concentrating Frame Relay connections

The MAX provides extensive support for Frame Relay. Using a T1 or E1 line or serial WAN
port for a nailed connection to a switch, it can function as a Network to Network Interface
(NNI) switch, a Data Circuit-terminating Equipment (DCE) unit responding to users, or as a
Data Terminal Equipment (DTE) unit requesting services from a switch.

Enabling X.25 terminal connections

X.25 is a precursor to Frame Relay and is generally considered less efficient. However, many
sites use it to transmit information between users across the WAN. It accommodates both
high-volume data transfers and interactive use of host machines. The MAX can have one
physical connection to an X.25 DCE unit at the other end of a T1, E1, or BRI line. To support
interactive use, the connection must be nailed.

Configuring routing and bridging across the WAN

Routing and bridging configurations enable the MAX to forward packets between the local
network and the WAN and also between WAN connections.

Enabling protocol-independent packet bridging

The MAX can operate as a link-level bridge, forwarding packets from the Ethernet network to
a WAN connection (and vice versa) on the basis of the destination hardware address in each
packet. Unlike a router, a bridge does not examine packets at the network layer. It simply
forwards packets to another network segment if the address does not reside on the local
segment.

MAX 6000/3000 Network Configuration Guide 2-5

Configuration Concepts and Profiles

Overview of MAX configuration

Using IPX routing (NetWare 3.11 or later)

The MAX can operate as an IPX router, linking remote NetWare LANs with the local NetWare
LAN on the Ethernet netw ork. IPX routing has its own set of concerns related to the
client-server model and user logins. For example, users should remain logged in for some
period even if the connection has been brought down to save connection costs.

IP routing

IP routing is the most widespread use of the MAX, and it has a wide variety of configurable
options. IP routing is the required protocol for Internet-related services such as IP multicast
support, OSPF, and cross-Internet tunneling for Virtual Private Networks (VPNs). Most sites
create static IP routes to enable the MAX to reliably bring up a connection to certain
destinations or to change global metrics or preferences settings.

Configuring Internet services

All Internet services and routing methods require that the MAX function as an IP router, so an
IP routing configuration is a necessary precondition.

Multicast

The Multicast Backbone (MBONE) is a virtual network layered on top of the Internet to
support IP multicast routing across point-to-poin t lin ks . It is often used for transmitting audio
and video on the Internet in real time, because multicasting is a much cheaper and faster way to
communicate the same information to multiple hosts.

OSPF routing

Open Shortest Path First (OSPF) is the next generation Internet routing protocol. The MAX
can be configured to communicate with other OSPF routers within an Autonomous System
(AS). To enable this routing function, you must configure the OSPF options on the Eth ernet
interface and for each WAN connection that supports remote OSPF routers.

OSPF can import routes from RIP as well. Y o u can control how these imported external routes
are handled by adjusting systemwide routing options such as route preferences and ASE-type
metrics.

Virtual Private Networks

Many sites use the Internet to connect corporate sites or to enable mobile nodes to log in to a
corporate backbone. Such Virtual Private Networks (VPNs) use cross-Internet tunneling to
maintain security or to enable the Internet to transport packets that it would otherwise drop,
such as IPX packets. To implement VPNs, the MAX supports both Ascend Tunnel
Management Protocol (ATMP), which is a Lucent proprietary tunneling mechanism, and
Point-to-Point Tunneling Protocol (PPTP).

ATMP enables the MAX unit to create and tear down a tunnel to another unit. In effect, the
tunnel collapses the Internet cloud and provides direct access to a home network. Packets
received through the tunnel must be routed, so ATMP currently applies only to IP or IPX
networks.

2-6 MAX 6000/3000 Network Configuration Guide

A PPTP session occurs between the MAX and a Windows NT server over a special TCP
control channel. Either end might initiate a PPTP session and open the TCP control channel.
Note that opening a PP TP session does not mean that a call is active. It simply means that a call
can be placed and received.

A profile is a group of related parameters and always appears as a menu item in the VT100
interface. Many profiles contain subprofiles which are, essentially, submenus within a profile.
Whether a profile is called a profile or a subprofile depend s on th e contex t because almo st an y
profile can be considered a subprofile in some sense.

To access a profile, you must have the necessary privileges. To activate a profile so that its
settings take effect, you need further privileges.

Obtaining privileges to use the profiles

As explained in the Installation and Basic Configuration Guide, privileges are often required
for changing settings in MAX profiles. To activate a profile, for example, you need full
privileges. Unless you have a personal profile that grants full privileges, you must activate the
Full Access profile. Proceed as follows:

1 At the Main Edit Menu, press Ctrl-D.

The Main Edit Menu’s DO menu appears.

2 Select P (Password).
3 Press Enter or the Right Arrow key.

The Security menu appears, displaying a list of Security profiles.

4 Select Full Access.
5 Press Enter or the Right Arrow key.

A password-entry field appears.

6 Enter your password within the brackets.
7 Press Enter or the Right Arrow key.

If your password is accepted, you have Full Access privileges.

8 Press Enter.

The Main Edit Menu reappears.

Activating a profile

When you have full privileges, you can make a profile active. Proceed as follows:

1 Open the profile that you want to make current.
2 Press Ctrl-D.

The profile’s DO menu appears.

3 Select L (Load).

The Load profile....? menu appears.

Saving a profile

When you exit a profile after changing any of the settings, you are prompted to accept or
discard the changes. You must select the accept option if you want to retain the new settings.
For example, to create a new Line Config profile, complete each of the following steps:

1 Open Net/T1 > Line Config and select an unconfigured profile.
2 Press the Right Arrow key and enter a descriptive name as the setting for the Name

parameter.

3 Continue setting the parameters that are relevant for your environment.
4 When you have set all the relevant parameters, press the Back Arrow key to exit the

profile. The following message appears:

EXIT?

0=ESC (Don’t exit)
1=Exit and discard
2=Exit and accept

5 Select the number that reflects the action you want to take.

Using RADIUS

You can use RADIUS to externally authenticate connections answered by the MAX unit.
External authentication centralizes the management of WAN connections, and concentrates
user profiles into a single text file. The use of RADIUS also enables token-card authentication
for secure networks, or authentication based on a UNIX password database. For details about
obtaining and installing the Ascend RADIUS daemon and dictionary, and for a sample users
file, see the TAOS Radius Guide and Reference.

RADIUS profiles are composed of three parts:

User-Name Check-Items
Reply-Items

The User-Name must be left justified. It is typically the name of the caller (or calling device),
but it may also be a phone number (for CLID or DNIS authentication), a special string
indicating a pseudo-user profile, or the string
details about pseudo-user profiles, see the TAOS Radius Guide and Reference.

Check-Items must be on the same line as the User-Name, and must be separated by white
space (space or tab) from the User-Name. Check-Items includes zero or more attribute-value
pairs that must match the attributes that are present in the Access-Request for the user to be
authenticated. Check-Items typically include the password for the entry.

Reply-Items must be indented and separated from the User-Name and Check-Items by a
newline. (If a Reply-Item is not indented, it is interpreted as the User-Name of a new entry.)
Reply-Items includes zero or more attribute-value pairs that are returned in Access-Accept
messages to authorize services for the user.

Both RADIUS and TACACS+ enable administrators to keep track of connection statistics,
usually for billing purposes. For details on session accounting see the T AOS Radius Guide and
Reference.

A MAX unit supports up to four T1- or E1-line connections. It also has a serial WAN port,
which typically connects to a Frame Relay switch, and six slots for expan sion cards. Ex pansion
cards can provide other types of WAN connections. Digital-modem cards and V.110-modem
cards provide communications with analog modem users and V.110 Terminal Adapter users,
respectively. In Japan, MAX units support Personal Handyphone System (PHS). You can
install and configure an ISDN BRI card if yo ur conn ections do not warrant the expense o f a T1
or E1 line. With the Host/BRI module, the unit emulates a telco switch providing ISDN BRI

lines to local hosts. The BRI/LT card supports Lucent’s ISDN Digital Subscriber Line (IDSL)
standard for voice and data transmissions. To provide the bandwidth needed for video
teleconferencing, Host/AIM6 and Host/Dual cards support two types of inverse multiplexing:
Bandwidth ON Demand Interoperability Group (BONDING) and Ascend Inverse
Multiplexing (AIM). If your unit connects only to ISDN lines and supports o nly
digital-modem cards, call routing is preconfigured . You must configure it, howe ver, if you
have a mixtu re of cards or if the WAN lines do not support ISDN signaling.

Introduction to WAN configuration

Introduction to WAN configuration

To configure a MAX unit, you set parameters in the VT100 menus. (For a description of
navigating the interface, see the Installation and Basic Configuration Guide for your MAX.)
Many of the menus and submenus include profiles, which are groups of related parameters. To
begin setting the parameters, you must understand how the VT100 menus relate to slots and
ports. You must also understand telephone number assignments and how a MAX unit routes
inbound and outbound calls.

How the VT100 menus relate to slots and ports on the MAX 6000

The menus in the VT100 interface are numbered to correspond to slots in the MAX 600 0 unit.
A slot can be an actual expansion slot or virtual slot on the unit’s motherboar d. Virtual slots

include the System slot, two T1 or E1 slots, the Ethernet slot, the Etherdata slot, and the Serial
WAN slot.

T1 or E1 slots

The built-in T1 or E1 connections are slot 1 and slot 2 (menus 10-000 and 20-000,
respectively). Each of these slots accommodates two T1 or E1 lines. The menus for
configuring and testing the lines are organized as follows:

Expansion slots

The six expansion slots are slots 3–8 (menus 30-000 through 80-000), numbered as shown in
Figure 3-1. (Before installing an expansion card, be sure to read any instructions that might be
packaged with the card.)

Ethernet and WAN slots

Slot 9 is the Ethernet slot (menu 90-000). The Ethernet menu contains submenus and profiles
related to the local network, routing and bridging, and WAN connectio ns. Slot A, Etherdata
(menu A0-000), is a virtual slot that provides support for 32 Ethernet sessions (to supplement
those supported by the Ethernet card). The serial WAN port is slot B (menu B0-000)

Note: There are no parameters associated with the Etherdata card. T here is no submenu und er
Etherdata on the Main menu. The Ethernet card and Etherdata card are the same type of card.
The Ethernet card allows 64 simultaneous Ethernet sessions. You configure the Ethernet
interface by means of parameters in Ethernet submenus. Each Etherdata card allows an
additional 32 Ethernet sessions.

Configuring WAN Access

Introduction to WAN configuration

How the VT100 menus relate to slots and ports on the MAX 3000

Depending on the model, a MAX 3000 unit has six BRI ports, two T1 or E1 ports, a T1 or E1
drop and insert port, and a serial port for WAN access. It also has two expansion slots. For the
purpose of organizing the menus in the VT100 interface, ev ery po rt o n the u nit is as signed to a
slot. Except for two expansion sots, the slots are virtual. That is, they exist only for the sake of
organizing the menus to correspond to the physical ports.

The Ethernet port is slot 4 (menu 40-000). The Ethernet menu contains submenus and profiles
related to the local network, routing and bridging, and WAN conn ections.

The Etherdata slot is slot 5 (menu 50-000), representing Ether Data HDLC channels. The
Etherdata card gives the MAX 32 extra use r Ether net ses sions. Without the Etherdata card, the
MAX supports only 64 simultaneous Ethernet sessions. With two Etherdata cards, the unit can
support 128. Etherdata data cards are no longer available as expansion cards. MAX units
configured for T1 units have 1 virtual Etherdata card built onto the motherboard, and MAX
units configured for E1 units have 2 virtual Etherdata cards built onto the motherboard.

The serial port is slot 6 (menu 60 -00 0). It is use d fo r the s erial WAN connection or a nailed-up

3-4 MAX 6000/3000 Network Configuration Guide

Assigning telephone numbers

A MAX unit receives calls on telephone numbers assigned to its T1 or E1 and (if applicable)
Net/BRI channels. Each number has a limit of 24 characters, which can include the following:

1234567890()[]!z-*#|

T o ass ign the numb ers, yo u must und erstan d add-o n numb ers, hu nt grou ps, and Servi ce Profi le
Identifiers (SPIDs).

Add-on numbers

You build multichannel calls (MP, MP+, AIM, or BONDING) by specifying add-on numbers.
A multichannel call begins as a single-channel connection to one telephone number. The
calling unit can then request and store additional numbers that it dials to connect additional
channels. To add channels to the call, the calling unit must integrate the add-on numbers with
the number it dialed initially. The parameters you set to specify add-on numbers depend on the
type of line you are configuring. For a T1 or E1 line, set the Ch N# parameters. For a BRI line,
set the Pri Num parameter. For some BRI lines, (that is, for multipoint mode) you must also set
the Sec Num parameter.

Configuring WAN Access

Introduction to WAN configuration

The group of channels used for a multichannel call is called a bundle. A 10-chan nel bun dle, in
which each channel is 64Kbps, provides a 640 Kbps connection. Typically, the telephone
numbers assigned to a bundle share a group of leading digits. Enter only the unique digits
identifying each number, as follows:

• If the add-on number in the called unit is shorter than the telephone number dialed by the
calling unit, the MAX unit replaces only the rightmost digits. For example, suppose you
dial 777-3330 to reach channel 1 of line 1, and dial 777-3331 through 777-3348 to reach
other channels (on the same line or a different line). In this case, set Ch1# to 30, and set
the Ch N# parameter for each of the other channels to 31, 32, and so forth.

• If the add-on number is longer than the number dialed, the unit discards the extra digits.
For example:

– Ch1#=510-655-1212
– Dial#=655-1212
– Derived number for channel 1=655-1212

• If there is no add-on number, the derived number equals the dialed number. For example:
– Ch1#=(null)
– Dial#=555-1213
– Derived number for channel 1=555-1213

Note: The most common reason multichannel calls fail to connect beyond the initial
connection is that the answering unit sends the calling unit add-on numbers it cannot use to dial
the other channels. For example, AIM and BONDING call bund les shou ld n ot span d ial plans.
If you are receiving AIM or BONDING calls and have multiple dial plans, set up each dial
plan as a separate trunk group. This also prevents MP and MP+ call bundles from spanning
dial plans. If you have, for example, two PRI lines fr om different service providers, you might
set the ChN Trnk Grp parameters for the first line to 9 and for the second line to 8. For more
information about trunk groups, see “Enabling trunk groups” on page 3-68.

MAX 6000/3000 Network Configuration Guide 3-5

Configuring WAN Access

Introduction to WAN configuration

Hunt groups

A hunt group is a group of channels to which the carrier assigns a single telephone number.
When a call comes in on that number, the Central Office switch delivers the call to the first
available channel. Because channels in a hunt group share a common telephone number, the
add-on numbers in the profile are the same.

Note: If all of a line’s channels have the same add-on number, you can leave the telephone
number assignment blank.

SPIDS (for Net/BRI lines)

The Service Profile Identifiers (SPIDs) assigned to a BRI line operating in multipoint mode are
numbers used at the Central Office switch to identify services provisioned for your ISDN line.
Your carrier bases the SPIDs on the telephone numbers assigned to your BRI lines, and tells
you the SPIDs when it installs the lines.

Most, but not all telephone companies include a suffix on their SPIDs. When receiving SPIDs
from your telephone company, ask whether or not suffixes are included. The following SPID
formats have been agreed upon by most telephone companies.

For an AT&T switch in multipoint mode , SPI Ds have one of the following formats:

01

nnnnnnn

01

nnnnnnn

0
00

In the AT&T SPID formats, nnnnnnn is the 7 digit telephone number (not including the area
code). For example, if the telephone number is 555-1212, the SPID is 0155512120 or

01555121200. For a Northern Telecom switch, SPIDs have one of the following formats:

aaannnnnnnSS
aaannnnnnnSS

00

In the Northern Telecom SPID formats, aaannnnnnn is the 10-digit telephone number
(including the area code). SS is an optional suffix. If included, the suffix is a 1 or 2 digit
number differentiating the channels. For example, if the telephone numbers are 212-555-1212
and 212-555-1213, the SPIDs might be:

21255512121
21255512132

or:

212555121201
212555121302

In some cases, the suffix is followed by 00 (for example, 21255512130200).

How a MAX unit routes inbound and outbound calls

When a MAX unit receives a call on one of its WAN interfaces, it routes that call internally to
one of its slots or ports. When a digital modem, AIM port, or a host on the local Ethernet port
originates a dial-out connection, the unit routes that call internally to an available WAN
channel to place the call. The channel configuration of a WAN line determines how the

3-6 MAX 6000/3000 Network Configuration Guide

channel routes inbound calls and places outbound calls. For details, see “Configuring call
routing” on page 3-58.

Configuring T1 lines

A MAX 6000 unit that supports T1 lines has two T1 slots, each of which supports two T1
lines. Configure a Line Config profile for each of the two slots. You can also configure
additional Line Config profiles, but only one can be active for a given slot at a given time. For
a MAX 3000 unit, only one Line Config profile can be active at a given time. In addition to a
few general parameters, a Line Config profile contains a subprofile for each line connected to
the slot. Each subprofile provides parameters for configuring the line’s connection to the
Central Office switch. You can customize the settings for monitoring line quality and
supporting PBX connections. Other parameters apply to carrier-specific services. Also, you
can enable the MAXDAX feature, which routes incoming calls from inbound T1 or PRI lines
to specific outgoing channels on the same or different T1 (inband) or PRI lines. Each of the
two subprofiles also includes parameters for configuring individual channels within the line.

Setting the general parameters

Configuring WAN Access

Configuring T1 lines

To create a new T1-line configuration, open the Net/T1 > Line Config menu and display an
available profile:

Net/T1

Line Config

Line Config profile

Name=
1st Line=
2nd Line=
Line 1...
Line 2...

Set the Name parameter to assign a descriptive name to the configuration. (You can configure
multiple profiles for the same slot and activate a profile when it is needed. To activate a profile,
see “Activating a profile” on page 2-7.)

You can set 1st Line and 2nd Line to Trunk (indicating a standard T1 interface with signaling
information), Quiesced, or Disabled. For the second line connected to a MAX 6000 E1 slot,
you can also specify D&I (Drop-and-Insert) service. (A MAX 3000 unit has no D&I setting for
the 2nd Line parameter. Instead, line 3 can be used for D&I only.) Drop-and-Insert on the
second line specifies that some of the first line’s channels transparently move to the second
line. A device such as a PBX connected to the second line is not aware that the channels
actually pass through the MAX unit. For more information about each parameter , see the MAX
Reference.

Configuring WAN Access

Configuring T1 lines

Connecting to the Central Office switch

T o conf igure a line’s connection to the Central Office switch, open the Net/T1 > Line Config >
Line Config profile > Line N subprofile for the line and set the following parameters:

Parameter Specifies

Sig Mode The signaling type for the line.
NFAS ID Num An interface ID number for a line using Non-Facility Associated

Signaling (NFAS). Each NFAS line must have a different ID number.

Rob Ctl The robbed-bit call-control mechanism that the MAX unit uses for

inband signaling.
Switch Type Type of switch (carrier specific) providing the ISDN service.
Framing Mode Physical-layer frame format of the T1 line.
Front End Type of interface used on the T1/PRI port. Select CSU (the default) if

you plan to use the MAX unit’s internal CSU, or select DSX if you

plan to connect the port to other equipment that provides the interface

to the WAN, (an external CSU, for example), and disable the internal

CSU.
Encoding Type of encoding that the line uses at the physical-link layer.
Length The distance between the CSU and the MAX unit. Applies to a MAX

using external CSUs only.
Buildout Amount of attenuation, in decibels, to apply to the internal CSU.

Consider specifying a value if the MAX is using an internal CSU too

near a repeater. For additional information, consult your carrier.
Clock Source That the line can (Yes) or cannot (No) be used as the clock source for

timing synchronous transmission s between the sending and the

receiving device. A MAX unit only has one clock source. The firs t line

that comes up is the clock source for all the lines. If you set this

parameter to No, the MAX uses its internal clock.
Collect DNIS/ANI That DNIS and CLID information from the switch are (Yes) or are not

(No) available for authentication and accounting. Applies to inband

signaling only. With the Yes setting, the Digital Signal Processor

(DSP) decodes the calling and called DTMF digits.
Send Disc Number of seconds the MAX unit waits, from the time the call is

presented, before clearing the call.

For detailed information about each parameter, see the MAX Reference.

Signaling mod e

You must configure the signaling type (Sig Mode) for each T1 line.
If you set Sig Mode to ISDN_NFAS, you can also establish an interface ID or NFAS ID

number for this type of signaling. You must specify a different interface ID for each NFAS
line.

3-8 MAX 6000/3000 Network Configuration Guide

If you set Sig Mode to Inband signaling (also called robbed-bit signaling), you must set the
Rob Ctl parameter to specify a call-control mechanism. For additional information, consult
your carrier.

Switch-specific settings

Set the Switch Type parameter to specify the network switch providing ISDN service on the
T1/PRI line. The carrier supplies the setting. You must also specify the physical layer frame
format for the T1 line by setting the Framing Mode parameter.

Front-end settings

The Front End parameter specifies the type of Channel Service Unit (CSU) used for the T1
line. Your carrier can assist you in setting the Encoding parameter. This parameter specifies the
Layer-1 line encoding used for physical links, which affects the way the digital signals on the
line represent data. Set the Length parameter if you are using an external CSU. If using the
internal CSU, ask your carrier about a value, if any, for the Buildout parameter.

Monitoring line quality

Configuring WAN Access

Configuring T1 lines

The telephone company uses a Facilities Data Link (FDL) protocol to monitor the quality and

performance of T1 lines. In a line’s subprofile, set the FDL parameter to specify the protocol.
If you are not sure which FDL protocol to specify, your telephone carrier can tell you.

Supporting PBX connections

In a MAX 3000 unit’s T1 slot, or in either T1 slot of a MAX 6000, you can connect line 2 to a
PBX. The unit can act as a switch, moving an incoming call from line 1 to line 2. You can
assign the PBX a number for dialing out through the MAX unit. If the second line’s signaling
mode is PBX T1, you can route calls to the PBX. For all calls received by the PBX, you can
specify a sample count to provide accurate tone detection and decoding. To support PBX
connections, you set the following parameters in the Net/T1 > Line Config > Line Config
profile > Line N subprofile:

Parameter Specifies

PBX Type The type of signaling to be used with the PBX on line 2.
Delete Digits The number of digits to be deleted from the beginning of the dialed

number to allow a PBX on line 2 can dial out through the MAX unit.

Add Number A series of digits to be added to the beginning of the dial-out telephone

number after the digits specified by Delete Digits have been removed.

Ans # A telephone number to be used for routing calls received on the first T1

line to the device terminating the second T1 line when the second line’s
signaling mode is PBX T1. The answer number is one of the unit’s
telephone numbers. (For more information, see “Configuring call
routing” on page 3-58.”)

Ans Service A data service (voice, for example). Any call that uses the specified data

service will be routed to line 2,. This parameter can be used as an
alternative to Ans # when the second line’s signaling mode is PBX T1.
(For more information, see “Configuring call routing” on page 3-58.)

Input Sample
Count

For detailed information about each parameter, see the MAX Reference.

Allows the PRI-T1 conversion process to use number (one or two) of sets
of Goertzel samples the PRI-T1 conversion process is to use for DTMF
tone detection. By default, the MAX uses only one sample to decode
signals from robbed-bit PBXs, because some PBX devices have a tone
duration of less than 50ms, which does not provide enough time to
compute two sets of Goertzel samples. The PRI-T1 convers ion proces s is
more accurate when the MAX can use two samples. Using two samples is
recommended when the tone duration is longer than 70ms.

Configuring carrier-specific services

To enable the MAX to communicate with your carrier’s switch, and vice versa, obtain values
for the Call-by-Call, T1-PRI:PRI # Type, and T1-PRI:NumPlanID parameters from your
service provider . The v alue specified for the Call-by-Call parameter sets th e signaling value for
routing calls. The T1-PRI:PRI # Type and T1-PRI:NumPlanID parameters specify values that
the MAX unit applies to outbound calls on PRI lines so that the switch can properly interpret

To configure carrier-specific services, open the Net/T1 > Line Config profile > Line N
subprofile for the line you are configuring and set the following parameters:

Parameter Specifies

Call-by-Call Service provider’s call-by-call signaling value for routing calls from a

local device to the carrier’s network through the MAX unit.

T1-PRI:NumPlanID NumberPlanID field in the called party’s information element.

For detailed information about each parameter, see the MAX Reference.

Using MAXDAX

MAXDAX enables you to route incoming calls from T1 or PRI lines to specific outgoing
channels on the same or different T1 or PRI lines. To implement MAXDAX, you must set
parameters in the Net2Net Incoming Calls and Net2Net ChanGroup ID profiles. In the
Net2Net Incoming Calls profile, you define parameters used in configuring channels on which
the MAX unit receives incoming calls. In the Net2Net ChanGroup ID profile, you define
parameters used in configuring channels for outbound calls.

For complete information about MAXDAX, see “Configuring MAXDAX” on page 3-73. Or,
for detailed information about each parameter, see the MAX Reference.

Following are the parameters you set in the Net/T1 > Line Config profile > Line N > Net2Net

to Switched.

Each built-in T1 line provides 24 channels, each of which can support one single-channel
connection. Depending on the signaling mode used on the line, all 24 chann els are available for
user data, or 23 channels are available for data and the 24th channel is reserved for signaling.
Each channel can be either switched or nailed. You can assign a switched channel to a slot/port
combination. To make a nailed channel available, you assign the channel to a group, and then
assign that group number to the Connections or call profile.

Following are the relevant parameters, which are in each Net/T1 > Line Config > Line Config
profile > Line N subprofile. (In the parameter names, N represents a number distinguishing an
individual parameter from other parameters of the same type.)

Parameter Specifies

Ch N Type of connection that supports the channel.
Ch N # Any add-on telephone number as sociated with a switched channel

only .

Ch N Slot A slot number for switched calls to be routed to and from this

channel.

Ch N Prt/Grp For switched calls, a port number to be used with the Ch N Slot

parameter for call routing purposes. For nailed channels, the
group number of the nailed channels used for the connection.

Ch N Trnk/Grp Trunk group to which a nailed channel is assigned to make it

available for outbound calls.

Hunt-N # A hunt-group number (a telephone number) associated with the

T1 line in a specific Line N profile. Your carrier assigns the hunt-
group number.

For detailed information about each parameter, see the MAX Reference.

MAX 6000/3000 Network Configuration Guide 3-11

Configuring WAN Access

Configuring T1 lines

The Ch N parameters are repeated for each channel in the line. (There are 23 channels if you
use PRI signaling and 24 channels if you use robbed-bit signaling.)

The Ch N # parameter is an add-on number associated with each switched channel (as

described in “Add-on numbers” on page 3-5).

Associating a c hannel with a slot/ port in the MAX unit

With the Ch N Slot and Ch N Prt/Grp parameters, you can assign a switched channel to a slot or
slot/port combination for a digital modem, AIM port, or Ethernet network. This configuration
affects both inbound call routing and outbound calls. In effect, it reserves the channel for calls
to and from the specified slot or port. (For details, see “Configuring call routing” on
page 3-58.)

Assigning nailed channels to groups

If the channel is nailed, Ch N Prt/Grp specifies a group number to which the channel belongs.
To make use of this nailed connection, a Connection or call profile references the group
number. (You use a call profile to configure a Host interface. A call profile is analogous to a
Connection profile. A call profile is associated with a video-conferencing host. There can be
only one video call up at one time, so there is only one active call profile. The call profiles are
located in Host/Dual (or Host/AIM6) > PortN menu > Directory > any call profile.)

Assigning channels to tr unk groups

You can assign trunk-group numbers 4–9 to channels to make them available for outbound
calls. (For details, see “Routing outbound calls” on page 3-68.)

Assigning channels to hunt groups

If your carrier provides hunt-group server, you must set the Hunt-N# parameter to specify the
hunt group number that the carrier has configured on the CO switch. When dial-in clients
require additional bandwidth, the MAX forwards the hunt group number to the client. This
process is built into the bandwidth allocation protocols.

You can assign a hunt-group number (a telephone number) associated with the T1 line in a
specific Line N profile. Assign this value to the Hunt-N # parameter.

Typical T1 configurations, with examples

Typical T1-line configurations for MAX units include configurations for ISDN PRI services,
robbed-bit signaling, NFAS signaling, PRI-to-T1 conversion for a T1 PBX, and assigning
bandwidth to a nailed link.

Configuring a line for ISDN PRI service

When configuring ISDN PRI service for a MAX unit, you must configure ISDN signaling for
the line. Optionally, you can configure the unit to send either ISDN code 16 (Normal call
clearing) or code 17 (User busy) when the PRI switch servicing the unit triggers the T310
timer. Also, you can configure overlap receiving if you want the unit to obtain complete
called-number information from the network switch.

Configuring WAN Access

Configuring T1 lines

Configuring ISDN signaling

T o conf igure a T1 line for ISDN signaling, proceed as follows:
1 Open a Net/T1 > Line Config > Line Config profile and, depending on which line you are

configuring, set the 1st Line or 2nd Line parameter to Trunk. For example:

Net/T1

Line Config

Line Config profile

Name=
1st Line=Trunk
2nd Line=Disabled

2 Open the subprofile for the line you have set to trunk service, and set the signaling mode

to ISDN. For example, if you set 1st Line to trunk, set the Sig Mode parameter in the Line
1 subprofile:

Line 1...

Sig Mode=ISDN

3 In the same subprofile, specify the framing and encoding values. For example:

Framing Mode=ESF
Encoding=B8ZS

4 Exit the Line Config profile and, exit the profile, at the exit prompt, select the exit and

accept option.

If the profile you have configured is not the active profile, activate it as described in

“Activating a profile” on page 2-7.

Configuring the Pre-T310 timer

The ISDN Pre-T310 timer feature enables users calling into a MAX unit to get better
clarification of the reasons for call disconnects during the initial setup of the call. If a call is
presented to the unit, and there is an extended period of delay while the call is being set up (for
example, heavy local Ethernet traffic is slowing down RADIUS requests or DNS lookups),
you might want your users to get a disconnect indication other than the generic Normal call
clearing.

In compliance with CCITT Specification Q.931, the unit sends a Call Proceeding message to
the network switch for every call it accepts.

The network switch sets its T310 timer as it awaits further messages from the MAX unit. The
switch tears down the call if the T310 timer expires. In this event, the switch reports ISDN
code 16 (Normal call clearing) to the calling device.

To use the MAX ISDN Pre-T310 timer, it must be set to a time period less than that of the
T310 timer on the switch. Then, after the MAX unit’s Pre-T310 timer expires but before the
switch’s T310 timer expires, the MAX sends ISDN code 17 (User busy) and clears the call.

Note: Only calls presented on T1/PRI lines support the Pre-T310 timer feature.

T o conf igure the Pre-T310 timer, proceed as follows:

1 Open a Net/T1 > Line Config > Line Config profile > Line N subprofile.
2 Set the Send Disc parameter to a value of from 0 to 60 seconds.

MAX 6000/3000 Network Configuration Guide 3-13

Configuring WAN Access

Configuring T1 lines

The parameter must be set to a value less than that of the switch’s T310 timer value, so
that it expires before the T310 timer.

3 Open the Ethernet > Mod Config > Auth subprofile.
4 Set the Timeout Busy parameter to Yes if you would like User Bu sy sent when the Send

Disc timer expires. Set Timeout Busy to No if you would like Normal call clearing sent.
Note: The Timeout Busy parameter replaces the CLID Timeout Busy parameter.

If the profile you have configured is not the active profile, activate it as described in
“Activating a profile” on page 2-7.

Overlap receiving for the MAX unit

Overlap receiving affects the incoming-call-establishment procedure at the MAX unit.
According to ITU’s Q.931 specifications, the receiving unit can use either the en-bloc
receiving procedure or the overlap receiving procedure to handle the incoming call. If en-bloc
receiving is in use, the Setup message contains all the information required by the called user
for processing the call. But if the carrier supports overlap receiving, the received Setup
message might contain incomplete called-number information. After the network receives the
Setup Acknowledge message, it sends the remainder of the call information (if any) in one or
more Information messages. In this case, you must set the Overlap Receiv ing parameter to Yes
so that the unit can gather the complete called-number from the network switch, thus enabling
the use of features such as called-number authentication.

proceed as follows:

1 Open a Net/T1 > Line Config > Line Config profile and, depending on whi ch line you are

configuring, set the 1st Line or 2nd Line parameter to Trunk.

2 Open the subprofile for the line you have set to Trunk, and set Sig Mode to Inband.
3 In the same profile, specify the Rob Ctl parameter to specify the robbed-bit call-control

mechanism required by your carrier.

4 Set the Framing Mode parameter to specify the physical-layer frame format of the T1 line.

Enabling a robbed-bit PBX with PRI access lines (PRI-to-T1 conversion)

If your WAN uses ISDN PRI signaling on its T1 lines, a MAX unit can convert the signaling to
standard T1 for use with a PBX. With this configuration, the MAX emulates a WAN switch,
such as a Lucent 5ESS, connected to the PBX.

Note: In most cases, you cannot use this feature in combination with digital modems. Also,
the PBX must use two-state inband with DTMF signaling and must support Senderized (en
bloc) digital transmission, because the MAX unit has a preset time limit on received dialing
digits. In addition, the called number should be available from the switch. That is, you need
Dialed Number Identification Service (DNIS) or a called number information element.

On a MAX 6000 unit, T1 PBX must connect to line 2 of the unit’s second slot. That is, you
must configure line 2 in a profile in the 20-000 Net/T1 > Line Config menu. To configure the
Line Config profile that will support the PBX, set the 2nd Line parameter to Trunk. T hen, open
the subprofile for second line connected to the PBX and set the following parameters:

Configuring T1 lines

Parameter Specifies

Sig Mode The signaling mode. Select PBX T1.
Rob Ctrl The robbed-bit call-control mechanism.
T1-Pri:PRI # Type Type of calls placed by the PBX. Ask your PRI provider about

which settings are available to you.

T1-PRI:NumPlanID NumberPlanID, needed by the carrier’s switch to properly

interpret a dialed number. Ask your PRI provider about which
settings are available to you.

PBX Type The type of service the PBX expects on its T1 line. In most

installations the PBX expects voice-service calls with call
progress tones. The Data setting does not supply call progress
tones or information messages to the user.

Ans Service The type(s) of call(s) that should be converted from PRI to

robbed-bit T1 signaling. Most installations select Voice. With this
setting, the unit converts voice-service calls arriving on the PRI
line to T1 voice calls for the PBX. Data-service calls undergo
normal incoming-call routing. They are not converted and sent to
the PBX.
Note that with Ans Service set to Voice, you cannot configure the
line for both PBX T1 support and digital modem operation,
because the voice-service modem calls are diverted to the PBX
and never r each the digit al modems.

Ans # A telephone number to be used for routing incoming calls from

the first T1 line to the second T1 line. Most installations leave this
setting blank. If specified, it can be an add-on number.

For more information about each parameter, see the MAX Reference.

Other considerations for PRI-to-T1 conversion

On a MAX unit with multiple lines configured for ISDN (PRI), each outgoing call from the
PBX uses the first channel available on any PRI line. To specify a PRI line for outgoing calls,
the PBX must preface its dialed numbers with the dialing prefix specified by the Ch N
TrnkGrp parameter in the Line N profile for the line used by the PBX. Also, you must enable

trunk groups by setting the Sys Config profile’s Use Trunk Grps parameter to Yes.
For incoming calls, note that the MAX unit does not forward the called number to the PBX.

Example of PRI-to-T1 configuration

Following is an example of a configuration for PRI-to-T1 conversion. Only the relevant
parameters are shown. In this example, line 2 is connected to the PBX, and line 1 is configur ed

Assigning bandwidth to a nailed link

A nailed link is always active. Both ends of the link must assign the same number of channels
to the link. However, channel assignments do not have to match. For example, a nailed link
that uses a single channel might have channel 1nailed at the local end and channel 12 nailed at
the remote end.

To designate channels for a nailed line, open Net/T1 > Line Config > Line Config profile and
make sure that the line whose channels you are designating is set to Trunk (that is, 1st Line or
2nd Line must be set to Trunk). Then open the subprofile (Line 1 or Line 2) for that line, and
configure the nailed channels. For each channel that is to be nailed, set the Ch N parameter to

3-18 MAX 6000/3000 Network Configuration Guide

Configuring WAN Access

Configuring E1 lines

Nailed, and set the Ch N Prt/Grp parameter to specify the channel’s group number. For
example:

Ch 2=Nailed
Ch 2 Prt/Grp=3
Ch 3=Nailed
Ch 3 Prt/Grp=3
Ch 4=Nailed
Ch 4 Prt/Grp=3
Ch 5=Nailed
Ch 5 Prt/Grp=3

In a Connection profile, you can use this permanent link by setting the Group parameter to
specify the nailed channels’ group number. In a Frame Relay profile, you can use a permanent
nailed link by setting the Nailed Group parameter to specify the group number.

If the profile you have configured is not the active profile, activate it as described in
“Activating a profile” on page 2-7.

Performing T1 line diagnostics

A MAX unit’s software provides the following T1 diagnostic commands:

Net/T1

Line Diag

Line LB1
Line LB2
Switch D Chan
Clr Err1
Clr Perf1
Clr Err2
Clr Perf2

Y o u can use these comman ds to test the line conf iguration. For detailed info rmation about each
command, see the MAX Reference.

Configuring E1 lines

A MAX 6000 unit that supports E1 lines has two E1 slots, each of which supports two E1
lines. Configure a Line Config profile for each of the two slots. You can also configure
additional Line Config profiles, but only one can be active for a given slot at a given time. For
a MAX 3000 unit, only one Line Config profile can be active at a given time. A Line Config
profile contains a few general parameters and two subprofiles, one for each line connected to
the slot. Each subprofile provides parameters for configuring the line’s connection to the
Central Office switch. You can customize the settings for call setup and DPNSS or DASS 2
switches. Other parameters apply to timing and telephone numbers. Each of the two
subprofiles also includes parameters for configur ing individual channels within the line.

Setting the general parameters

To begin creating a new E1-line configuration, open the Net/E1 > Line Config menu and
display an available profile:

Line Config

Line Config profile

Name=
1st Line=
2nd Line=

Line 3...

Set the Name parameter to assign a descriptive name to the configuration. (You can configure
multiple profiles for the same slot and activate a profile when it is needed. To activate a profile,

see “Activating a profile” on page 2-7.)

You can set 1st Line and 2nd Line to Trunk (indicating a standard E1 interface with signaling
information), Quiesced, or Disabled. For the second line connected to a MAX 6000 E1 slot,
you can also specify D&I (Drop-and-Insert) service. (A MAX 3000 unit has no D&I setting for
the 2nd Line parameter. Instead, line 3 can be used for D&I only.) Drop-and-Insert on the
second line specifies that some of the first line’s channels transparently move to the second
line. A device such as a PBX connected to the second line is not aware that the channels
actually pass through the MAX unit.

You can set the back-to-back parameter to configure DASS-2 and DPNSS lines in a
back-to-back connection. A crossover cable connects an E1 port of one MAX to an E1 port of
another MAX. No switch is required, an d the connection is entirely local. One MAX shou ld be
set up for DTE operation, and the other for DCE operation.

For more information about each parameter, see the MAX Reference.

Connecting to the Central Office switch

To configure a line’s connection to the Central Office switch, open the line’s subprofile in the
Line Config profile and set the following parameters:

Parameter Specifies

Sig Mode The signaling type for the line.
Switch Type Type of switch (carrier specific) providing the ISDN service.
Framing Mode Physical-layer frame format of the E1 line.

For detailed information about each parameter, see the MAX Reference.

Signaling mod e

You must configure the signaling type (Sig Mode) for each E1 line.

3-20 MAX 6000/3000 Network Configuration Guide

Configuring WAN Access

If you set Sig Mode to ISDN_NFAS, you can also establish an interface ID or NFAS ID
number for this type of signaling. You must specify a different interface ID for each NFAS
line.

If you set Sig Mode to Inband signaling (also called robbed-bit signaling), you must set the
Rob Ctl parameter to specify a call-control mechanism.

Switch-specific settings

Set the Switch Type parameter to specify the network switch providing ISDN service on the
E1/PRI line. The carrier supplies the setting. You must also specify the physical-layer frame
format for the E1 line by setting the Framing Mode parameter.

Defining settings for DPNSS or DASS 2 switches

If you are connecting a MAX unit to a standard DPNSS or DASS2 switch, you do not have to
change the DPNSS/DASS2 settings. But connection to a nonstandard switch could require
changes in these settings. Also, if you connect two units back-to-back, you have to change
settings for the unit that acts as the network (PBX) side. Following are the relevant parameters,
which are in each Net/E1 > Line Config > Line Config profile > Line N profile

Parameter Specifies

connected back-to-back, specify CCITT Layer 2 by setting the L2 End parameter to specify
which of the PBX devices will send.

When the E1 line connects to a DPNSS or a DASS-2 switch, you must set the NL Value
parameter to specify the maximum number of retransmissions that can be sent on the line. Set
the LoopA voidance parameter to s pecify the maximum number of transit PBX devices through
which a call can be routed.

Enabling a line for Clock Source use

To specify which lines can provide Clock SOurce, set the following parameter located in
Net/E1 > Line Config > Line Config profile > Line N subprofile:

Parameter Specifies

Clock Source That the line can (Yes) or cannot (No) be used as the clock source for

timing synchronous transmission s between the sending and the
receiving device. A MAX unit only has one clock source. The firs t line
that comes up is the clock source for all the lines. If you set this
parameter to No, the MAX uses its internal clock.

For detailed information about each parameter, see the MAX Reference.

Setting triggers for call-completed information

If you enable the overlap receiving feature, your MAX unit can gather the complete called
number from the network switch through a series of information messages, and can therefore
support features such as called-number authentication. Provide information about the called
number itself by setting PRI Prefix # and Trailing Digits. Once the MAX receives the called
number, the PRI Prefix # value determines the number of digits the MAX matches as the prefix
to the number. Th e Trailing Digits number indicates the number of digits the MAX requires to
indicate the end of a called number. Open Net/E1 > Line Config > Line Config profile > Line N
profile and set the following parameters:

Configuring channels

Each built-in E1 connection supports 32 channels, each of which can support one
single-channel connection. Depending on the signaling mode used on the line, all 32 channels

For detailed information about each parameter, see the MAX Reference.

Associating a c hannel with a slot/ port in the MAX unit

With the Ch N Slot and Ch N Prt/Grp parameters, you can assign a switched channel to a slot or
slot/port combination for a digital modem, AIM port, or Ethernet network. This configuration
affects both inbound call routing and outbound calls. In effect, it reserves the channel for calls

to and from the specified slot or port. (For details, see “Configuring call routing” on
page 3-58.)

Assigning nailed channels to groups

If the channel is nailed, Ch N Prt/Grp specifies a group number. To make use of this nailed
connection, a Connection or call profile references the group number.

You can assign trunk-group numbers 4–9 to channels to make them available for outbound
calls. (For details, see “Routing outbound calls” on page 3-68.)

Assigning channels to hunt groups

You can assign a hunt-group number (a telephone number) associated with the E1 line in a
specific Line N profile. Assign this value to the Hunt-N # parameter.

Typical E1 configurations, with examples

Typical E1-line configurations for MAX units include configurations for ISDN signaling,
DPNSS signaling, and nailed connections.

Using ISDN signaling

To configure an E1/PRI line for ISDN signaling in Belgium, the Netherl ands, Switzerland,
Sweden, Denmark, or Singapore:

1 Open the Net/E1 > Line Config > Line Config profile > Line N subprofile for the line you

are configuring, and set the Sig Mode parameter to ISDN. For example:

Net/E1

Line Config

Line Config profile

Line 1...

Sig Mode=ISDN

2 Set the Switch Type parameter to Net 5 (the standard used in these countries):

Switch Type=Net 5

3 Specify G.703 framing (the standard used by most E1 ISDN providers):

Framing Mode=G.703

Configuring WAN Access

Configuring E1 lines

Note: If you select G.703, the MAX unit provides C RC-4 check ing. If you s elect 2 DS, it
does not.

4 Exit the profile and, at the exit prompt, select the exit and accept option.
If the profile you have configured is not the active profile, activate it as described in

“Activating a profile” on page 2-7.

Using DPNSS signaling

To configure an E1 line for DPNSS signaling:
1 Open the Net/E1 > Line Config > Line Config profile > Line N subprofile for the line you

are configuring.

2 Set the DPNS S signaling mode and a compatible switch type. For example:

Net/E1

Mercury is a variant of DPNSS.

3 Set the framing mode. For example:

Most E1 DPNSS providers in the U.K. require 2DS, which is a variant of G.703. If you
select G.703, the unit provides CRC-4 checking. If you select 2DS, it does not.

4 Make sure th at the fo llowing parameters are set to their default values, as shown:

5 Exit the profile and, at the exit prompt, select the exit and accept option.
If the profile you have configured is not the active profile, activate it as described in

“Activating a profile” on page 2-7.

Setting up a nailed connection

The number of nailed channels must be the same at both ends of the connection, but the
channel assignments do not have to match. For exampl e, if there are five nailed chann els at the
local end, there must be five nailed channels at the remote end, but channel 1 could be
switched at the local end and nailed at the remote end.

To use nailed channels, a Connection or call profile references the group number specified by
each channel’s Prt/Grp parameter. A total of 64 nailed connections can be defined.

To configure nailed channels on line 1 of an E1 slot:
1 Open the Net/E1 > Line Config > Line Config profile > Line 1 subprofile:

channels 1–5 to the same nailed connection:

Ch 1=Nailed
Ch 1 Prt/Grp=3
Ch 2=Nailed
Ch 2 Prt/Grp=3
Ch 3=Nailed
Ch 3 Prt/Grp=3
Ch 4=Nailed

Ch 5=Nailed
Ch 5 Prt/Grp=3

3 Exit the profile and, at the exit prompt, select the exit and accept option.
If the profile you have configured is not the active profile, activate it as described in

Network Terminating (NT) support for European ISDN PRI

You can configure MAX units as Network Terminating (NT) devices for European ISDN
E1/PRI connections. To configure the MAX for NT mode, you set the ISDN TE/NT Mode
parameter to NT.

ISDN call information

Configuring E1 lines

If the E1/PRI line switch type is German 1TR6 or Japan NTT, you can display information
about ISDN calls by invoking the terminal-server command line and entering the Show Calls
command. For example:

ascend% show calls

The command displays statistics about current calls. For example:

Call ID Called Party ID Calling Party ID InOctets OutOctets
3 5104563434 4191234567 0 0

4 4197654321 5108888888 888888 99999

The Call ID column contains an index number specific to the call.
Called Party ID and Calling Party ID show the telephone number of the answering device and

calling device, respectively.
InOctets and OutOctets show the number of bytes received by the answering device and

transmitted by the calling device, respectively.
When an ISDN call disconnects from either a German 1TR6 switch or a Japan NTT switch, th e

switch sends call billing information to the call originator as part of the call tear-down process.
This information is written to the eventCallCharge (eventEntry 17) SNMP object in the
Ascend Enterprise MIB events group (10). An SNMP manager can then read this object to
determine the cost of the call. The eventCallCharge object is a read-only integer and is
applicable only if eventType is callCleared (3). Otherwise, 0 is returned.

Configuring WAN Access

Configur ing the serial WAN port

Configuring the serial WAN port

A MAX unit has a built-in V.35 serial WAN DB-44 port. A serial WAN port provides a
V.35/RS-449 WAN interface that typically connects to a Frame Relay switch. To configure the
serial WAN port, open the Serial WAN > Mod Config profile and set the following parameters:

Parameter Specifies

Module Name A descriptive name for the interface. (This parameter is optional.

Functionality is not affected if you do not enter a value.)

Nailed Grp The group number that supports the serial WAN connection. Because a

serial WAN connection is nailed, you must assign a group number to each
nailed channel. More than one nailed channel can use the same group
number.

Activation The signal or signals the system uses to indicate that the Data

Circuit-terminating Equipment (DCE) is ready to connect.

Ext. Clock * 1K Maximum bandwidth that the unit uses for the nailed portion of a

Nailed/MP+ call. The externally generated clocking speed you specify is
multiplied by 1024 to calculate the bandwidth.

For detailed information about each parameter, see the MAX Reference.

Configuring a serial WAN connection

To configure the serial WAN interface to connect to a Frame Relay switch that uses static data
flow, proceed as follows:

1 Open a Net/T1 > Line Config > Line Config profile > Line N subprofile.
2 Make sure at least one Ch N Prt/Grp parameter has been set to specify a nailed gro up.
3 Exit the profile and, at the exit prompt, select the exit and accept option.
4 If the profile you have configured is not the active profile, activate it as described in

“Activating a profile” on page 2-7.

5 Open Serial WAN > Mod Config.
6 Assign a module name and a nailed group number.
7 Set the Activation parameter to Static to specify that the MAX unit will not use flow

control signals, because the DCE is always connected:

8 Exit the profile and, at the exit prompt, select the exit and accept option.
9 Configure a Frame Relay profile and specify the Nailed Grp number assigned to this port.

For more information about Frame Relay, see Chapter 5, “Configuring Frame Relay.”

Configuring digital modems

A digital modem is a device that connects to a digital line (such as an ISDN line) and
communicates with a modem that is connected to an analog line at the other end of the
connection.

Configuring WAN Access

Configuring digital mod ems

A digital modem accepts an incoming call as a Pulse Coded Modulation (PCM) encoded
digital stream that is a digitized version of the waveform sent by an analog modem. The digital
modem also sends outgoing data as a PCM-encoded digital stream for transmission across the
WAN to an analog modem.

T o configure digital modems, you can assign telephone numbers to specify routing to available

modems. When the MAX receives a modem call on a PRI line, the call’s ISDN call setup
message notifies the unit that the call is a modem call. Inband calls have no setup mess age, so
you must assign telephone numbers to route modem calls correctly. To shut the T1/PRI lines
down without disconnecting callers, you can quiesce digital-modem slot cards.

56K modem numbering

The digital modems on a K56Flex modem card are numbered for identification, but the
numbering is not in a continuous sequence. The numbering sequence for an 8-MOD modem
card does not use the number 4, 5, 8, or 9, and the sequence for a 12-MOD card does not use
number 10 or 11.

Note: 56K modem nu mbering onl y applies to units that support 8-MOD or 12-MOD cards.

8-MOD modem numbering

Modems in the 8-MOD modem card are numbered 0, 1, 2, 3, 6, 7, 10, 11.

For example, if you have an 8-MOD modem card in slot 8 in a MAX 6000 and all eight
modems are idle, the terminal-server Show Modems command displays the following output:

ascend% show modems

8:10 7 idle
8:11 8 idle

12-MOD modem numbering

Modems in the 12-MOD K56Flex modem card are numbered 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 12, 13.
For example, if you have a 12-MOD K56Flex modem card in slot 8 in a MAX 6000 and all

eight modems are idle, the terminal-server Show Modems command displays the following
output:

ascend% show modems
slot:item modem status

8:0 1 idle
8:1 2 idle
8:2 3 idle
8:3 4 idle
8:4 5 idle

8:6 7 idle
8:7 8 idle
8:8 9 idle
8:9 10 idle
8:12 11 idle
8:13 12 idle

Parameters for configuring digital modems

The name(s) of the profile(s) that contain(s) the parameters for configuring your digital
modems depend(s) on which modem card(s) you have installed. The Main Edit Menu lists the
profile for the card you have installed.

If you have V.32bis (on a MAX 6000 only) modems inst alled in y our un it, t he Main Ed it Menu
shows the profile as LAN Modem. If you have K56 mo dems instal led, depending on the
number of modems installed per modem slot card, the Main Edit Menu shows the profile as
K56 Modem-8, K56 Modem-12, or K56 Modem-16.

Following are the parameters that appear for most of the cards available on the MAX unit:

Parameter Specifies

Module Name Your descriptive name for the Mod Config subprofile. (This param eter is

optional. Functionality is not affected if you do not enter a value.)

Modem # N Enable/disable an individual slot for modem use. (If th e card installed has

eight modems per modem slot card, there will be eight entries for this

parameter. If the card installed has 30 modems per modem slot card, there

will be 30 entries for this parameter.)

For detailed information about each parameter, see the MAX Reference.

Quiescing digital modems and returning them to service

If you set a Net/T1 or Net/E1 > Line Config > 1st Line or 2nd Line parameter to Quiesced, the
MAX disables all modems on the line without disrupting existing connections. W hen an active
call disconnects, that modem is added to the disabled modem list and is not available for use. If
all modems are on the disabled list, incoming callers receive a busy signal until the modems
have been restored for service. When you reenable a quiesced modem, a delay of up to 20
seconds might occur before the modem becomes available for service.

Note: Booting the MAX restores all quiesced lines, slots, and ports to service.
For more information about quiescing digital modems, see the 1st Line and 2nd Line

parameters, in the MAX Reference.

Sample configuration

Following is an example of configuring a V.90 S56 III Modem-30 module, (This modem card
contains 30 modems, but it is otherwise the same as a V.90 S56 III Modem-18 or V.90 S56 III

Configuring WAN Access

Configuring V.110 modems

Configuring V.110 modems

A V.110 card provides eight V.110 modems that each enable the MAX unit to communicate
with an asynchronous device over synchronous digital lines. An asynchronous device such as
an ISDN modem encapsulates its data in a V.110 protocol. A V.110 modem removes the V.110
encapsulation and enables an asynchronous session (a terminal-server session).

To configure a V.110 card, you assign answer numbers to the card, so that the MAX unit can

route calls to the card’s modem. The answer numbers can be add-on numbers as signed to some
of the MAX unit’s WAN lines. (For more information, see “Add-on numbe rs” on page 3-5.)

The V.110 modem processes the call and sends it to the MAX unit’s terminal-server software.
If the call does not contain PPP encapsulation, it is handled as a login call that can be routed
transparently to a Telnet host on the local network. PPP-encapsulated modem calls are passed
to the bridge/router as regular PPP connections.

Note: V.110 terminal adapters make asynchronous calls with CCITT V.110 encapsulation.
These calls require V.110 modem processing.

Routing calls to the V.110 modems

To configure V.110 modems, proceed as follows:

1 Open V.110 > Mod Config.
2 Optionally, specify a descriptive name for Module Name. (Functionality is not affected if

you do not enter a value.)

3 Set the V.110 module’s Ans N# parameters to specify the dial-in telephone numbers from

which incoming calls are to be routed to the module as terminal-server calls.

4 Exit the profile and, at the exit prompt, select the exit and accept option.

Configuring Personal Handyphone System (PHS)

Configuring Personal Handyphone System (PHS)

Personal Handyphone System (PHS) is a mobile telephone service currently offered in Japan
and other Asian countries only. In addition to voice communication, PHS offers data
communication at a bandwidth of 32 Kbps, and can thus provide Internet access as well as
voice service.

A MAX unit supports PHS through PHS slot cards, each of which supports 8 or 16 concurrent
PHS users. The unit supports up to two cards.

Y o u need to enable the software fu nctionality on the MAX through a has h code upgrade. When
you have installed this hash code, the System Options menu displays PHS Installed.
Otherwise, the System Options menu displays PHS Not Installed. Contact your Lucent
sales representative for details about enabling PHS support.

No further configuration is necessary. For example, when you boot up a MAX 3000 with a
PHS card in slot 2 or 3 and the unit software enabled, the following menu appears:

Main Edit Menu

00-000 System
10-000 Net/T1

30-000 PIAFS-8
40-000 Ethernet
50-000 Ether Data
60-000 Serial WAN
70-000 V.90 S56 III Modem

Personal Internet Access Forum Standard (PIAFS) is a protocol designed to support
connection negotiation, data transfers, and error correction. In the exam ple, the -8 refers to the

slot card’s support of eight concurrent PHS users. A card that supports 16 concurrent PHS
users is also available. That card appears as PIAFS-16 in the Main Edit Menu.

Note: MAX 6000 units support PIAFS protocol version 2.1 for PHS service. This PIAFS
version has an enhanced link-level protocol that supports dyn amic switching of data rates.
Depending on bandwidth availability, the protocol will select a 64 Kbps or 32 Kbps
transmission rate. Support for PIAFS protocol version 2.1 is controlled with a hashcode.
(MAX 3000 units currently support up to 32 Kbps. However, the next release of the MAX
3000 software will support PIAFS version 2.1, with 64 Kbps capability.)

Configuring ISDN BRI network cards

An ISDN Basic Rate Interface (BRI) network interface card supports eight BRI lines. These
lines can provide lower-cost connections to sites that do not require or have access to the
higher-bandwidth T1 or E1 lines. There are two types of BRI network cards: the U and the S
cards. Functionally, they are the same.

You can create multiple, alternative configurations for an ISDN BRI network card, storing
each configuration in a separate Net/BRI > Line Config profile. Only one such profile can be
active at a given time for a given Net/BRI slot. To activate a profile, see “Activating a profile”
on page 2-7. To create a Net/BRI configuration, open a Net/BRI > Line Config profile. You
have to assign a profile name and set a couple of other parameters that apply to the entire

profile, but most parameters are specific to a single line. You have to open each Line N
subprofile and set a few basic operational parameters, parameters for configuring the B
channels, and parameters for configuring add-on numbers and SPIDs.

Specifying a name and other settings for the profile

To begin configuring an ISDN BRI network card, open one of the Net/BRI > Line Config
profiles and set the following parameters:

Parameter Specifies

Name Descriptive name for the profile. You can configu re several pro f iles in a

Net/BRI slot and activate a profile when it is needed. (This parameter is

optional. Functionality is not affected if you do not enter a value.)
Switch Type Type of switch (carrier-specific) that provides the ISDN service for the

MAX.
BRI Analog

Encode

Support for user-selectable analog encoding for the BRI interface. If you

are going to receive modem calls, you can set this parameter to specify

the encoding type.

Setting a line’s basic operational parameters

When you are ready to begin configuring a specific ISDN BRI line, open the line’s Line N
subprofile and set the following parameters:

Parameter Specifies

Enabled Availability of an ISDN BRI line. If you set the Enabled parameter to No,

the line is not available for use.
Clock Source That the line can (Yes) or cannot (No) be used as the clock source for

timing synchronous transmissions between the send ing an d the receiving

device. A MAX unit only has one clock source. The first line that comes

up is the clock source for all the lines. If you set this parameter to No, the

MAX uses its internal clock.
Link Type Wheth e r the lin e is operating in point-to-point or multipoint mode.

In point-to-point mode, the MAX requires one telephone number and no

Service Profile Identifiers (SPIDS). In multipoint mode, the MAX

requires two telephone numbers and two SPIDS. All international switch

types except DBP Telecom, and all U.S. switch types except AT&T

5ESS, operate in multipoint mode.

For detailed information about each parameter, see the MAX Reference.

For detailed information about each parameter, see the MAX Reference.

BN Slot and BN Prt/Grp parameters

With the BN Slot and BN Prt/Grp parameters, you can assign a switched channel to a slot or
slot/port combination for a digital modem, AIM ports, or the Ethernet port. The slot/port
combination configuration affects both inbound call routing and outbound calls. In effect, it
reserves the channel for calls to and from the specified slot or port. For details, see
“Configuring call routing” on page 3-58.

Note: You cannot control whether an incoming call rings on the first or second B channel, so
set both BN Slot parameters to the same value.

If the channel is nailed, BN Prt/Grp is a Group number. T o make use of this nailed connection,
the Group number is referenced in a Connection or call profile.

BN Trnk Grp parameter

You can set the BN Trnk Gr p parameter t o configure trunk-group dialing for outgoing cal ls on
BRI lines supported by the ISDN BRI card. You can assign trunk-group numbers 4–9 to
channels to make them available for outbound calls. You cannot combine PRI channels with
BRI channels in the same trunk group. For details, see “Routing outbound calls” on page 3-68.

Configuring add-on numbers and SPIDs

The Pri Num and Sec Num parameters define additional telephone numbers for multichannel
calls, and SPIDs identify services provisioned for your ISDN line. For m ore det a ils about

add-on numbers and SPIDs, see “Assigning telephone numbers” on page 3-5.

To configure add-on numbers and SPIDs for your ISDN BRI line, open a Net/BRI line > Line
Config > Line Config profile, then open the line’s Line N subprofile and set the following
parameters:

Parameter Specifies

Pri Num Primary add-on number for the ISDN BRI line. If you configure the line

for point-to-point service, this is the only number associated with the line.
Pri SPID Primary Service Profile Identifier (SPID) for ISDN BRI line.
Sec Num Secondary add-on number for the ISDN BRI line. If you configure the

line for point-to-point service, Sec Num is not applicable.
Sec SPID SPID (Service Profile Identifier) associated with the secondary telephone

number for the ISDN BRI line.

For detailed information about each parameter, see the MAX Reference. For more information
about SPIDs, see “SPIDS (for Net/BRI lines)” on page 3-6.

Note: After you have configured the line, you might need to configure the card for outbound
calls (as described in “Configuring the Net/BRI line for outbound calls” on page 3-37).

Typical Net/BRI configurations, with examples

Typical Net/BRI line configurations for MAX units include configurations for incoming
switched connections and for outbound calls.

Configuring incoming switched connections

The following procedure assumes that the MAX BRI lines connect to a NI-1 switch running in
multipoint mode:

1 Open a Net/BRI > Line Config profile.
2 Set the Name parameter to assign a name to the profile.
3 Set the Switch Type parameter to specify the carrier switch type.
4 Set the BRI Analog Encode parameter to specify analog encoding for modem calls.
5 Open the Line 1 su bpr ofile, and set Enable to Yes to enable the line.
6 Set the Link Type parameter to specify multipoint mode.
7 Configure the B channels for switched usage and for routing to the local network.
8 Specify the primary and secondary add-on numbers and their associated SPIDs.
9 Close the Line 1 subprofile and proceed to configure the other seven lines, repeating

Configuring the Net/BRI line for outbound calls

To configure a Net/BRI line for outbound calls, you must assign the line to a trunk group. To
enable an outbound caller to use the line, specify the trunk group in the caller’s Connection
profile.

Assigning lines to trunk groups

T o enable local users to use BRI lines to initiate outbound connections, the MAX unit must be
configured for trunk groups. Proceed as follows:

1 Open the System > Sys Config profiles and set the Trunk Grps parameter to Yes to enable

trunk groups systemwide.

2 Exit the profile and, at the exit prompt, select the exit and accept option.
3 Open Ethernet > Mo d Config > WAN Options profile, and set the Dial Plan parameter to

Trunk Grp to specify that the digits following the first digit constitute an ordinary
telephone number.

By setting Dial Plan to Trunk Grp, you direct the MAX unit to use lines configured with
trunk groups for outbound calls.

4 Exit the profile and, at the exit prompt, select the exit and accept option.
5 Open the Net/BRI > Line Config > Line Config profile > Line 1 subprofile.

6 Set the B1 Trnk Grp and B2 Trnk Grp parameters to assign both of the line’s channels to

trunk group N.

7 Repeat this trunk-group setting for the remaining BR I lines (lines 2–8), so that all BRI

lines are in the same trunk group.

8 Exit the profile and, at the exit prompt, select the exit and accept option.

Specifying a trunk group in a Connection profile

To configure a Connection profile to specify the trunk group you have assigned to the BRI
lines, proceed as follows:

1 Open the Connection profile (in the Ethernet > Connections menu).
2 Includ e the Net/BRI trunk-group number in the setting for the Dial # parameter. For

example, the following setting specifies trunk group 6:

Ethernet

Connections

Connections profile

Dial #=6-555-1212

When the first digit of the Dial # setting is a trunk-group number, the MAX unit uses the
channels in that trunk group to place the call.

3 Open the Telco Options subprofile and set the AnsOrig parameter to Call Only , or to Both,

to enable outbound dialing.

4 Exit the profile and, at the exit prompt, select the exit and accept option.

Note there are other ways to configure outbound calls. Other features that support outbound
calls are: immediate modem services and port-to-port dialing.

For a way to use Destination profiles to specify lines as backup channels if all WAN channels
are busy, see “Routing outbound calls” on page 3-68. Instead of explicitly entering the dial
number in the Connection profile, you can reference a Destination profile that can specify up
to six different dial-out paths to a particular destination.

Displaying information about BRI calls

If the BRI line switch type is German 1TR6, yo u can display in formation about ISDN calls
from the terminal-server command line by entering the Show Calls command. For example:

ascend% show calls

The command displays statistics about current calls. For example:

Call ID Called Party ID Calling Party ID InOctets OutOctets
3 5104563434 4191234567 0 0
4 4197654321 5108888888 888888 99999

The Call ID column contains an index number specific to the call. Called Party ID and Calling
Party ID show the telephone number of the answering device and calling device, respectively.

InOctets and OutOctets show the number of bytes received by the answering device and
transmitted by the calling device, respectively.

Note: When an ISDN call disconnects in Germany, the ISDN switch sends call billing
information to the call originator as part of the call tear-down process. For lines that use the

3-38 MAX 6000/3000 Network Configuration Guide

German 1TR6 switch type, you can access ISDN call charges in the Ascend Enterprise MIB
through SNMP management utilities.

Configuring Host/BRI lines

The Host/BRI module provides up to eight local ISDN BRI lines. A line terminating one of
these local ISDN BRI lines might be a MAX unit (or any BRI device) on its own local Ethernet
segment, or a Desktop video device with its own BRI line and built-in terminal adapter. When
a MAX unit is connected to a Host/BRI line, it appears to be an AT&T switch.

Terminal Equipment devices on Host/BRI lines can call each other, making local
net-to-Net/BRI calls. These local calls never go out to the WAN. They make use of the BRI
bandwidth internally. They can also send and receive calls from the WAN. To the actual WAN

switch, the MAX unit appears as the call’s end point. Routing to the Host/BRI line is handled
internally.

Note: TAOS supports the European ISDN protocol for the eight- port Host/B RI card on MAX
units that are configured as Network Terminating (NT) devices (see ISDN TE/NT Mode
parameter in the MAX Reference). You can select this carrier switch type by setting the Switch
Type parameter to NET3.

Configuring Host/BRI lines

Typical Host/BRI configurations, with examples

Ally has a personal computer connected to a Pipeline 85™ unit. The Pipeline 85 connects to a
port on a MAX unit’s Host/BRI card. The unit connects to an external site by way of a PRI
line. Users external to Ally’s site need to access resources on her computer, so you must
configure the MAX to accept incoming calls and route them to the Pipeline 85 connected to
Ally’s computer. Jim requires a similar configuration, but he also needs access to the Internet,
so he must enable outbound calls. Sheila must share data with a user who is connected to one
of the other BRI lines attached to the MAX unit, so you must configure the unit for local
BRI-to-BRI calls.

Routing inbound calls to the terminating device

To route inbound calls to the terminating device:
1 Open a Host/BRI > Line Config profile and set the Name parameter to assign a name to

the profile.

2 Open the Line 1 or Line 2 subprofile.
3 Set Enabled to Yes to enable the line.
4 Set at leas t one Ans N# parameter to specify an answer number. This can be an add-on

number, as descr ibed in “Add-on numbers” on page 3-5.

5 To configure the other Host/BRI modules, or to create alternative configurations for the

same module, repeat step 2 through step 4.

6 Exit the profile and, at the exit prompt, select the exit and accept option.
If the profile you have configured is not the active profile, activate it as described in

“Activating a profile” on page 2-7.

Example of routing inbound calls

With the following configuration, the MAX unit routes inbound WAN calls to the device
terminating the Host/BRI line. That device does not make outbound calls to the WAN. The
inbound caller dials 555-1212, and the MAX unit connects the caller to the equipment that
terminates BRI line 1.

BN Slot and BN Prt/Grp parameters

With the BN Slot and BN Prt/Grp parameters, you can assign a channel to a slot or slot/port
combination for a digital modem, AIM port, or the Ethernet port. The slot/port combination
configuration affects both inbound call routing and outbound calls. In effect, it reserves the

channel for calls to and from the specified slot or port. For details, see “Configuring call
routing” on page 3-58.

Note: You cannot control whether an incoming call rings on the first or second B channel, so
set the BN Slot parameters to identical values.

With a nailed channel, BN Prt/Grp is a Group number. To make use of this nailed connection,
the Group number is referenced in a Connections or call profile.

Configuring IDSL voice-call support

The IDSL card supports incoming and outgoing voice calls. To support outgoing voice calls,
the connected Terminal Equipment (TE) must send digits to the MAX unit by means of Q.931
en-bloc dialing, that is, it sends all dialed digits to the unit in one block, the ISDN Call Setup
message, rather than one digit at a time.

The unit receives outgoing call requests from the device connected to the IDSL card and routes
voice calls to the Public Switched Telephone Network (PSTN) over a T1 line or ISDN PRI
line. The unit receives incoming voice calls on any attached T1 or PRI line, and uses Dialed
Number Identification Service (DNIS) to route the calls to devices connected to IDSL cards.

To configure IDSL voice-call support, open the System > Sys Config profile and set the
following parameters in each Line N Subprofile:

groups are not used, the call request terminates at the unit and is not forwarded to the
PSTN.

4 to 9.

Configuring the MAX to route incoming voice calls to the IDSL card

You can use one of two different methods or a combination of both to configure the MAX unit
to accept voice calls from the PSTN and route them to devices connected to an IDSL card. You
can instruct the unit to route calls to an IDSL card on the basis of either the called number or
the T1 channel on which the unit receives calls.

To instruct the unit to route calls to the IDSL card on the basis of the called number:

1 Open a BRI/LT > Line Config > Line Config profile > Line N subprofile.
2 Set Ans 1#, Ans 2#, or both to the called number that is dialed to reach the end user’s TE.

The Central Office (CO) switch must support DNIS, because the unit matches the DNIS
number of the incoming call to numbers specified by Ans N# parameters.

3 Repeat step 1and step 2 for each line that can receive calls that should be routed to the

IDSL card.

Performing loopback diagnostics for IDSL

The MAX unit supports loopback tests from the unit to any device on the IDSL connection.
For example, you can loop back the signal from the IDSL card to the remote device, or from
the IDSL card to any intermediate repeater. For example, with the connection shown in
Figure 3-3, you could set up a loopback test from th e unit to any of the ISDN repeaters, or from
the unit all the way to the remote device at the end of the connection. This ability enables you
to isolate trouble anywhere in the connection.

want to loop back.

2 Set the EOC Address parameter to one of the following values to specify the EOC

Address of the device that is the terminating point for the loopback test:
– 0—The remote TE or MAX unit
– 1—The repeater nearest the MAX unit
– 2–6—Subsequent repeaters. The next repeater after 1 is 2, and so on.
– 7—All devices

3 Select Line LoopBack command and press Enter.
4 In the confirmation dialog box that appears, select 1=Line N LB.

While the line loops back, normal data transfer is disrupted.

5 Press Escape to cancel the loopback.

In a local loopback test, data originating at the local site loops back to its originating port
without going out over the WAN. It is as though a data mirror were held up to the data at the
WAN interface, and the data reflected back to the originator. The WAN interface is the port on
the MAX unit that connects to a WAN line.

Configuring Host/AIM6 and Host/Dual ports

You can connect a videoconferencing codec (coder/decoder) to a port supporting inverse
multiplexing to communicate over a point-to-point link. The MAX supports two types of
Inverse Multiplexing: Bandwidth ON Demand Interoperability Group (BONDING) and
Ascend Inverse Multiplexing (AIM). Both types are supported by V.35, RS-449, or X.21 port
on the MAX unit. Ty pically, inverse-multiplexed calls are between video codecs and other
devices that might need high bandwidth serial data over the WAN.

Inverse multiplexing uses pins for controlling the data flow through the port. A device sends a
signal through a pin and over the line to another device. The signal indicates the control-line
state. For example, when a device sends a signal indicating that it has data to send, the
control-line state is RTS (R eques t to Send). If the other device s ends a signal to indicate that it
is ready to receive data, its control-line state is DTR (Data Transmit Ready). The process of
sending these synchronization signals between Inverse Multiplexing ports is called
handshaking.

You can install two types of inverse multiplexing cards on a MAX unit: Host/AIM6 and
Host/Dual. The Host/AIM6 card supports six ports and the Host/Dual card supports two ports.
Both cards support of the same dialing protocols: AIM/Bonding, RS-366, V.25 bis, and X.21.

Note: When you install a Host/AIM6 or Host/Dual card on the MAX unit, the card’s ports
become the default route for inbound data calls, taking precedence over the bridge/router
software. Make sure that your call-routing configuration accommodates calls destined for the
local Ethernet network. (For details, see “Configuring call routing” on page 3- 58.)

An AIM port requires three levels of configuration:

• Configure the AIM port itself

• Configure the interface to the codec

• Configure the WAN connections on the port

Pairing ports for dual-port calls

In a dual-port call, the codec performs its own inverse multiplexing on two channels so that a
call can achieve twice the bandwidth of a single channel. A pair of inverse multiplexing ports
on the MAX unit connects to the codec. The pair includes a primary and a secondary port.
Because the unit places the two calls in tandem and clears the calls in tandem, it considers
them a single call.

Creating a dual-port configuration does not prevent you from dialing any other type of call
from the primary host port of the pair, or from using either port for receiving any type of call.
Pairing ports does not disable RS-366 dialing at the secondary port.

Enabling dual-port cal ls

If you are configuring the interface to an older model codec that does not support inverse
multiplexing, you can pair two inverse multiplexing ports to provide double the bandwidth for
the videoconferencing call. A dual-port call requires a dual interface on the codec. The
following configuration pairs the first two inverse multi plexin g ports in a Host/AIM6 card:

1 Open Host/AIM6 > Mod Config.
2 Ass ign a name (optional).

Configuring Host/AIM6 and Host/Dual ports

Configuring WAN connections between serial hosts

To configure WAN connections between serial hosts, you not only set parameters that are

defined in the specifications you receive from the service provider’s Central Office (CO), but
you also set parameters on the basis of the condition of the line. To set the parameters for a
WAN connection, open a Host/AIM6 ( Hos t/Du a l) > PortN Menu > Directory > Directory
profile (the profiles in the Directory menu are referred to as call profiles), and set the following
parameters:

Parameter Specifies

Name Descriptive name for the profile. The value of the Name parameter

should be descriptiv e of the port.

Dial # Number used to dial out on this connection. Defines the far-end

number and can specify the method of placing the call.

Call Type Type of connection, such as switched or nailed, between the local and

remote codecs.

Call Mgm The way that the MAX manages calls at an inverse multiplexing port

when AIM, FT1-AIM, FT1-B&O, or BONDING is the value for the
Call Type parameter.

Data Svc The type of data service the link uses, such as 56K, 56KR, or 64K. The

Data Svc parameter affects how much bandwidth is available for a
particular session, and how channels can be allocated to the call.

Force 56 Whether the MAX uses only the 56-Kbps portion of a channel, even

when all 64-Kbps appear to be available. If you receive calls from
Europe or the Pacific Rim, use this parameter when the complete path
cannot distinguish between the Switched-56 and Switched-64 data
services.

Call-by-Call PRI service to use when using a Dial Plan, Connections or call profiles

to place a call. To set this parameter, contact your service provider,
who will supply you with the correct services information.

Bill # Telephone number to be used either as a billing suffix or the calling

party number.

Auto-BERT That an automatic Bit Error Rate Test (Auto-BERT) begins as soon as

a call connects and runs for the number of seconds you specify. MAX
status windows display the results.

Bit Inversion Whether or not the MAX performs bit inversion when it sends or

receives data over the WAN. Bit Inversion applies only to calls
between codecs. It turns data 1s into 0s and data 0s into 1s. In some
connections, you need to invert the data to avoid transmitting a pattern
that the connection cannot handle.

Fail Action The action that the MAX unit takes when it cannot establish the base

channels of a codec connection. When it cannot establish a call with
the number of channels specified by the Base Ch Count parameter , the
MAX unit can disconnect, reduce the bandwidth request, or establish a
lower bandwidth call and retry for the additional bandwidth.

PRI # Type The type of telephone number , such as National, Intl, or Local, that the

MAX unit dials for the outgoing call.

3-52 MAX 6000/3000 Network Configuration Guide

Parameter Specifies

NumPlanID A value supplied by the provider of your PR I line so that th e switch

can properly interpret the telephone number dialed.

Transit # A dialing prefix the MAX uses when making an outbound call. You

can specify a string for use in the transit network IE for PRI calling
when the call goes through an InterExchange Carrier (IEC). Transit #
does not apply to outbound calls on inband T1 lines.

Group The group number of a group of nailed channels assigned to the

connection. (A channel is assigned to a group in a Line N profile.)

FT1 Caller Whether the local codec initiates an FT1-AIM, FT1-B&O, or

Nailed/MPP call, or whether it waits for the remote end to initiate
these types of calls.

For detailed information about each parameter, see the MAX Reference.

Configuring bandwidth parameters

A MAX unit can allocate WAN bandwidth dynamically. When establishing a connection, the
unit opens the number of channels you specify as the base number of channels. It can add or
remove channels as required by the amount of traffic. You specify the increment by which the
unit adds channels and the decrement by which it removes channels. You need to further
fine-tune the channel allocation routine to avoid keeping channels active unnecessarily but also
avoid closing them too quickly. (Typically, you incur a minimum charge for opening a new
channel.) You can choose the algorithm to use for dynamic channel allocation. Also, each of
the available algorithms is based on the Average Line Utilization (ALU), and you can set
parameters that affect the calculation of ALU.

Configuring WAN Access

Configuring Host/AIM6 and Host/Dual ports

To configure bandwidth parameters for a WAN connection, open a call profile in the
Host/AIM6 (Host/Dual) > PortN Menu > Directory menu, and set the following parameters:

Parameter Specifies

Base Ch Count Base number of channels to open when setting up the call. After the

base channels have been opened for an AIM, BONDING, or
multichannel PPP call, the channel count can be augmented.

Inc Ch Count Number of channels the MAX unit adds as a bundle when bandwidth

changes either manually or automatically during a call. The unit adds
one bundle at a time.

Dec Ch Count Number of channels the MAX units closes as a bundle when

bandwidth changes either manually or automatically during a call. The
unit removes one bundle at a time. You cannot clear a call by
decrementing channels.

Dyn Alg The algorithm to use for calculating Average Line Utilization (ALU)

over the number of seconds specified by the Sec History parameter.
Sec History A time period, in seconds, that serves as the basis for calculating ALU.
Add Pers The time, in seconds, for which the ALU must exceed the value

Call Password and Flag Idle parameters

A call profile includes a Call Password and a Flag Idle parameter. The Call Password
parameter specifies the password for outgoing AIM and BONDING calls. The Flag Idle
parameter specifies the bit pattern that a dynamic call to an AIM port uses as the idle indicator.
Select the Yes setti ng to specify th e flag patt ern or the No se tting to specify the mark pattern.
Both patterns include enough 1 bits to maintain clock synchronization with the remote unit.
Both ends must use the same pattern. Receipt of the specified pattern indicates to the local unit
that the remote unit is not sending data.

For detailed information about each parameter, see the MAX Reference.

Configuring an AIM call

To configure an AIM call that uses dynamic bandwidth allocation to manage the call
dynamically:

1 Open a Host/AI M 6 (Host/Dual) > PortN Menu > Directory > call profile.
2 Set the Dial # to specify the remote device, and set Call Type to AIM.
3 Set C all Mgm to Dynamic.
4 Set Base Ch Count to specify the base number of channels and set Inc Ch Count and Dec

Ch Count to specify the number of channels to be added or subtracted, respectively, when
bandwidth requirements change.

5 Set the bandwidth parameters, as described in “Configuring bandwidth parameters” on

page 3-53.

Configuring the FT1-B&O call

While FT1 calls use nailed channels, FT1-AIM and FT1-B&O calls can combine switched
channels with nailed channels. For FT1-B&O calls, you must also set the B&O Restore
parameter. This parameter specifies automatic backup and overflow protection of nailed-up
circuits. It actually specifies how many seconds the MAX waits before restoring a nailed-up
channel to an FT1-B&O call.

Note: For FT1-AIM or FT1-B&O calls, you must set the Idle and Dial parameters in the Port
Config profile at both the local end and the remote end of the call. For the MAX unit to
connect the switched channels when you turn it on, set Idle to Call and Dial to Terminal. For
the unit to connect the switched channels when the host equipment at both ends activates DTR,
set Idle to None and Dial to DTR. In this latter configuration, the hosts at both ends of the
connection must activate DTR to make the unit connect the switched channels.

T o conf igure an FT1-B&O call:

1 Open the call’s profile in the Host/AIM6 > PortN Menu > Directory menu.
2 Set the call type to FT1-B&O.
3 Set call management to Dynamic. This setting is required in the device that initiates the

FT1-B&O call.

4 Specify the Group number for the nailed channels.
5 Set the FT1 Caller parameter to Yes to specify that the MAX unit initiates the call.

If the other end of the link initiates the call, set this parameter to No. Only one side of the
link can initiate the call for FT1 -A IM or FT1-B&O calls.

Configuring a dual-port call

In a dual-port call, two inverse multiplexing ports on the MAX unit connect the call to the
serial host. The two ports are a primary p ort and a secon dary port. Howev er , the unit places the
two calls in tandem and clears the calls in tandem, and considers them a single call. The
following restrictions apply to dual-port connections:

• The selected data service must be available end-to-end.

• The dialing method cannot be V.25 bis.

• The answer number must be the same for both ports.

• If trunk groups are in use, both channels of the call must be in the same trunk group.

Configuring WAN Access

Configuring Host/AIM6 and Host/Dual ports

In the following example, the Host interface profile must enable port pairing for dual-port

Configuring call routing

This section describes how to configure incoming and outgoing call routing on the MAX unit.
If you have a mixture of incoming calls, such as modem and digital, this section answers your
questions about routing those calls to the proper modules on the unit. This section also includes
a state diagram illustrating incoming call routing. The last part of the section describes how the
unit handles outbound calls.

Routing inbound calls

When the MAX unit receives a call on a WAN line, it performs CLID or DNIS authentication
(if available and configured), answers the call, and determines which slot should receive the
call. It then authenticates the call, builds a session, and passes the data stream to the
appropriate module or host. If a call is routed to the Ethernet port, the bridge/router software
forwards it to a host or hosts according to packet addresses.

Setting up ISDN subaddressing

When you use ISDN subaddressing in routing mode, incoming calls include a subaddress
number as part of the telephone number . When routing a call, the MAX unit first checks for the
ISDN subaddress. If the unit finds one, it uses the subaddress to route the call. If not, it goes on
to the next comparison.

To set up ISDN subaddressing:

1 Open the System > Sys Config profile.
2 Set the Ser ial, LAN, DM , and V.110 parameters to single-digit settings.
3 Exit the profile and, at the exit prompt, select the exit and accept option.

Example of ISDN subaddressing configuration

With the configuration in this example, the caller would dial 510-555-1212,3 to reach the
digital mo dems. The su baddress (3) follows the dialed number and is separated from it by a
comma.

Specifying answer numbers for destination host ports

If the MAX unit does not find an ISDN subaddressing, it checks for answer-number
specifications. If it finds a matching answer number, it uses that number to route the call. If
not, the unit goes on to the next comparison.

Each host port can specify one or more answer numbers. When the MAX unit receives an
inbound call and no subaddress is in use, it match es the called number to these answer numbers
and routes the call to the port with the matching number. Following are the related parameters

Configuring call routing

Specifying host ports’ slot and port numbers in WAN channel configurations

A MAX unit checks for slot and port number specifications. If the unit finds a matching slot
number, it uses it to rou te the call. (If the uni t also finds a port num ber, it routes to that specific
port on the slot number.) If not, the unit goes on to the next comparison.

In the configuration of WAN lines, you can assign one or more channels to a slot card. In the
case of an AIM slot card, you can assign channels to a port on the card. This channel
configuration affects both inbound call routing and the placement of calls. In effect, the
configuration reserves the channel for calls to and from the specified slot or port.

Configure slot and port routing only when answer number and ISDN subaddress routing are
not specified. Following are the related parameters (shown with sample settings):

When a MAX unit receives an inbound call and no subaddress is in use or no matching answer
number is found, it evaluates the slot and port specifications and ro utes the call to the specif ied
destination. For example, for the MAX 6000 shown in Figure 3-1 on page 3-2:

• 0 (zero, the default) specifies that this parameter is not used to route incoming calls.

• 1 and 2 are invalid settings, because they represent the built-in slots for T1 or E1 lines.

• 3–8 represent expansion slots. When looking at the back panel of the unit, slot 3 is the
bottom slot in the left bank of slots, followed by 4 and 5 in ascending order. Slot 6 is the
bottom right slot, foll owed by 7 and 8 i n ascending order.

• 9 represents the LAN. The unit routes calls to the bridge/router module.

Note: When a unit has more than one digital modem slot card installed, the cards and
modems form a pool, and any modem can answer a call routed to any digital modem slot.
