Warranty

Carrier Access warrants to BUYER that Product Hardware will be free from substantial defect in
material and workmanship under normal use in accordance with its Documentation and given proper
installation and maintenance for period of five years from the date of shipment by Carrier Access.

Carrier Access warrants that the Licensed Software, when used as permitted under its License Terms
and in accordance with the instructions and configurations described in the Documentation (including
use on Carrier Access product or a computer hardware and operating system platform supported by
Carrier Access), will operate substantially as described in the Documentation for a period of ninety
(90) days after date of shipment of the Licensed Software to BUYER.

This warranty shall not apply to Products or Software that have been either resold or transferred from
BUYER to any other party. Any such transfer voids the above warranty and related licenses. Carrier

component therein, or workmanship found to be defective so that the Product
hardware operates substantially in accordance with Carrier Access Documentation;
or

Preface

With respect to a warranty defect in the Licensed Software reported to Carrier Access by BUYER
during the 90-day software warranty period, Carrier Access, at its own expense and as its sole
obligation and BUYER's exclusive remedy for any breach of the software warranty, will use
commercially reasonable efforts to, at its option,

a. correct any reproducible error in the Licensed Software, or

b. replace the defective Licensed Software, as follows:

Should a Severity 1 or 2 warranty defect with the Software occur during the 90-day
warranty period, Carrier Access will provide, in its sole determination, either

1. software to resolve the defect to be downloaded into the affected units by the
BUYER or

2. a documented workaround to address the issue.

Severity 1 issues are failures of the Licensed Software to comply with the Carrier Access
software specifications and that completely or severely affect the Carrier Access Product and its
traffic or service capacity, or maintenance or monitoring capabilities.

Severity 2 issues are failures of the Licensed Software to comply with the Carrier Access
software specifications and that result in a major degradation of the Carrier Access Product so
as to impact its system or service performance, or significant impairments to network operator
control or effectiveness. Should a Severity 3 warranty defect with the Licensed Software occur
during the 90-day warranty period, Carrier Access will provide assistance to Buyer to determine
if a solution or workaround will be provided in a subsequent software release following the
reported issue.

Severity 3 issues are defined as failures of the Licensed Software to comply with the Carrier
Access software specifications but that do not significantly impair the function or service of the
Carrier Access Product or the system.

Determination of Severity 1, 2 or 3 shall be made solely by Carrier Access following receipt of
the reported problem. Refurbished material may be used to repair or replace the Product.
BUYER shall bear the risk of loss for Products or Software returned to Carrier Access for repair,
replacement, or service, and the same must be shipped pre-paid by BUYER.

business hours. Normal business hours for Carrier Access Customer Support Center are 7:00 a.m. to

Introduction

Overview

Overview

This manual covers the Router menu-driven user interface only, all other information
for the Router can be found in the Adit 600 User Manual.

The Router can be configured using CLI via telnet, through the Router Menu-driven
software.

The CMG Router has the following versions:

 CMG Service card

 CMG-01 Service card

 CMG-02 Service card

 CMG/CMG-02 Service card with G.729

Windows displaying the G.729 feature will be clearly noted in this manual.

Installation

The Router card can be installed into any of the service card slots (1-6) of the Adit 600
chassis. This card is hot-swappable, therefore the card can be removed and replaced
without bringing down the system or with or without power to the unit.

Install a Router Card

1. Slide the Router card into a service card slot of the chassis.

2. Press firmly into slot to engage, until card is seated completely.

3. Card has completed bootup when a solid Red CRD light (an LED) is displayed.

Install Country Specific Ringer Tones

The CMG Router card ships with a set of call progress tone files that allow call progress
tone definitions for a number of other countries to be used.The tones are played to a
VoIP endpoint at the direction of an external MGCP call agent. By default the call
progress are defined to match the United States standard call progress tones.

Tones are loaded via TFTP directly to the CMG Router card. All supported country
tones are provided on the software CD with the CMG Router. For more information see
the Adit 600 User Manual.

1-2 CMG Router - Release 2.7

Introduction

Maneuvering in the System

NOTE: Use of ringer tones requires an Adit 600 Controller with release 5.0 or
higher and CMG Router release 1.1 or higher.

Syntax: load {cmg_card-addr} tftp {"tone_file"}
Example: load 2 tftp "us.tdb"

Once a tone file is loaded into a CMG Router card it will remain in effect until replaced
by another. It is not removed when the CMG Router card is set back to its default
settings.

 CMG G.729A feature must be enabled, with a software key

 Specified voice channel has Fax configured as T38reserved or T38

 G.729A codec is enabled

<none> - Fax calls to/from the voice channel are handled as normal voice calls. Note: G711mu is
the only codec that will result in good fax and modem calls. In this mode echo cancellation must
be OFF for modem calls, and ON for fax calls.

<bypass> - Fax calls to/from the voice channel are handled using the fax bypass procedure (Gateway-

controlled fax bypass using NSEs). After a call is connected to the channel in voice mode, if a fax
tone is detected on the channel, the CMG will transmit NSEs to the remote gateway to tell it to switch
to a G.711 codec and then it will switch to a G.711 codec itself for that channel and disable silence
suppression. For the switchover to be successful, the remote gateway must also switchover to G.711.
The form of G.711 (mu-law or A-law) to which the codec is switched will be the form which has the
highest priority in the negotiated codec list. Note: Either G711mu or G711a must be on the

algorithm preference list for Fax Bypass to work.

<T38> - Fax calls to/from the voice channel are handled using T.38 method (Gateway-controlled

T.38 fax relay using NSEs) if DSP resources are available. When no DSP resources are available
(6 active T.38 fax calls) the card will reject the T.38 connect request and revert the channel to fax
bypass mode using the G.711 codec.

<bypass> - Modem calls to/from the voice channel are handled using the modem bypass procedure

(Gateway-controlled modem bypass using NSEs). After a call is connected to the channel in voice
mode, if a modem tone is detected on the channel, the CMG will transmit NSEs to the remote gateway
to tell it to switch to a G.711 codec and then it will switch to a G.711 codec itself for that channel and
disable silence suppression. For the switchover to be successful, the remote gateway must also
switchover to G.711. The form of G.711 (mu-law or A-law) to which the codec is switched will be
the form which has the highest priority in the negotiated codec list, or the one offered by the far end
gateway. Note: for modem calls (not fax calls), the gateway that initiated the bypass

(terminating gateway) then sends a "Disable echo cancellation" NSEs (193). After this both
gateways should turn off echo cancellation.

Signaling Type

<FXS LS> - FXS Loop Start. Default.
<FXS GS> - FXS Ground Start.

Short Inter Digit - Configures the short interdigit user dialing timeout on a voice channel. This

is the time allowed between dialed digits when the T or I address template specification is in effect.
For example, if the address specification is "xxxxT", and 4 digits have been dialed, this short timeout
is in effect. If the timer expires, the call will be routed to the destination. If another digit is dialed
before the timer expires, address processing will continue, using the long interdigit timeout. The
range is 1-10 seconds, with a default of 4.

Long Inter Digit - Configures the short interdigit user dialing timeout on a voice channel. This

is the total time allowed between dialed digits after the first, unless short timing is in effect. If the
originator does not dial the next digit in this time period, the call is torn down. The range is 1-60
seconds, with a default of 16.

Echo Cancellation - Enables/disables echo cancellation as the default for voice calls for a voice

channel.

<Disabled> - Disable echo cancellation as the default for voice calls.
<Enabled> - Enables echo cancellation as the default for voice calls. Default.

Echo Tail (ms) - Defines the maximum round-trip delay expected in the voice path between the

CMG and the phone, including acoustical delay at the phone. Options are: <8>, <16>, <24>, <32>
and <64>. Default is <16> milliseconds.

Voice Channels

VOIP Algorithm Preference Order - Defines the order preference of voice coding

algorithms for VoIP calls, on the specified voice channel(s). Up to 6 algorithms can be listed, in order
of preference. This list limits the acceptable codecs for a particular voice channel to those specified.
This can be used to limit voice channels that have a modem or fax machine attached to use only

G.711. Default settings list all algorithms, selections can be changed to none.

Repeat Count

Set the number of initial RTP message repeats at the time of signal transition. Range is 0-10
repeats. Default is 2.
Note: a repeat of 2 times, in essence is a message, followed by 2 repeats.

Repeat Interval

Set the interval of RTP messages at the time of transition in milliseconds. Range is 1-50
milliseconds, with a default of 5.

Refresh Interval

Set the periodic refresh interval of RTP signaling states. Range is 500-4000 milliseconds, with

LAN (Local) Profile Setup

LAN (Local) Profile Setup

The LAN Profile is the largest, most detailed portion of the Router software. The fields
on this screen allow definition of how data transmission will occur on the unit’s LAN
port. This includes defining the protocol(s) that it will use to send and receive data,
defining security protocols, specifying which LAN servers and networks will be
advertised to WAN units, and establishing specific data filtering options.

The LAN profile is used in conjunction with the WAN profiles. The WAN profiles
identify which remote units the local unit can communicate with, as well as the data
transmission requirements of each remote.

In addition to the fields on this screen, there are several other areas that directly relate
to the communication abilities of the Adit unit. You may use the fields at the bottom of
this screen to access the following areas:

 Defining static addresses at the local unit

 Establishing static networks

 Establishing Remote (WAN) advertising

 Establishing DHCP Server/BOOTP Relay Agent parameters

 Defining data filters

The Router can accommodate a maximum of 500 filters, such as those created when
establishing static routes or data filters. The following entries consume a filter:

 Configured address, custom and protocol filters

 Static IP networks and static IPX networks

 Enabling any learned items listed on the Advertise Network/Server screen or

Filter Network/Server screen

 Static IP and MAC Addresses

 Firewall filters

In a large network, it is necessary to selectively use of each of these options so that the
number of configured filters is within the maximum allowed.

The Local Profile is used to define the Local (LAN) port parameters for the unit at the
present location.

The (LocalUnit) is the default name for this unit and will be used during the authentication
process to ensure this unit’s identity. This name can easily by changed by simply typing over
the "LocalUnit" and saving when closing this window. This name can be up to 11 characters.

Protocol

This column includes three protocol options, IP, IPX and Other. These protocols are used to
define Frame Types and LAN Network Updates to be used by this Adit unit.

Frame Types

Define the frame type of the packets that are sent and received by the Adit. If a packet is received
formatted in a frame type that has not been enabled, the Adit will not accept the data.

NOTE: Multiple frame types may be supported simultaneously for IPX and
Other protocols.

802.2

When selected (X) this Adit may send and receive packets that match the 802.2 format. The 802.2
format complies with IEEE specifications.

Eth II

When selected (X) this Adit may send and receive packets that match the Ethernet II format. Note
that the IP protocol commonly uses this format.

SNAP

When selected (X) this Adit may send and receive packets that match the SNAP (Subnet Network
Address Protocol) format.

802.3

When selected (X) this Adit may send and receive packets that match Novell’s X802.3 format.

LAN Network Updates

Use the LAN Network Updates field to determine whether the Local (LAN) unit will learn, via
RIP and SAP packets, which networks and services are attached to the local LAN, and whether

Remote (WAN) networks and services will be advertised to the LAN. If this information is
learned, it may be advertised to remote devices if advertising is established. Use the

[SPACEBAR] to select from the following options: <Both>, <Neither>, <Send> and

<Receive>.

LAN IP:

IP Address

This is the IP Address of this Adit, used to uniquely identify the device on the internetwork. The
default for this IP Address is 10.0.0.1

Subnet Mask

A subnet mask determines which bits in the IP address are used to identify the network number.
The default for the Subnet Mask is 255.0.0.0.

Default Router

This is an optional entry depending on your network configuration. Use this field to identify a
router that is physically connected to your LAN. If the Adit receives a packet which contains a
network that is not known, the packet will be sent to the router identified in this field.

If there are other routers and networks behind the Default Router add Static Network IP

information with the Default Router as the Default Gateway.

If you are communicating with different network domains, you will need to enter the IP Address
of your Adit as the default router on each workstation or make sure that the local router will
redirect to the Adit when appropriate, so that they may use the Adit to reach the remote site.

LAN IPX:

These fields enable the Adit to route IPX to Remote (WAN) networks, even if an IPX server
does not exist on the local LAN. Typically, the Adit will learn its external network number.
However, if the local LAN does not have a server or if the LAN NETWORK UPDATES field
(see above) is set to <Neither>, and you wish to route IPX to Remote (WAN) networks, the
external network number must be defined using these fields.

If you are not using IPX on your LAN, these fields will not apply. Please note that these
are all hexadecimal entries. For the following see you network administrator for the
appropriate numbers. If the frame type is unsupported leave the field set to 0s.

802.2 Ext. Network

Enter the corresponding IPX external network number.

Ethernet II Ext. Network

Enter the corresponding IPX external network number.

SNAP

packets will be forwarded to/from the LAN. See Filters on page 4-18, for more information.

<Advertise Networks/Server >

Enables the unit to advertise all networks and services to all remote units, or to advertise to no
remotes. See Advertise Network/Server on page 4-25, for more information.

<DHCP Server/BOOTP Relay >

Establish the Adit as a DHCP Server or BOOTP Relay Agent. See DHCP Server/Client/Relay on
page 4-30, for more information.

<LAN Collision Threshold >

Adjust the threshold at which excessive LAN collisions trigger an alarm. See LAN Collision
Threshold on page 4-36, for more information.

<Secondary IP Address >

Add a secondary IP address and subnet to the specified LAN interface. The router will then be capable
of routing between subnets on the LAN interface or between the LAN subnets and any WAN subnet.
A maximum of 8 secondary IP addresses can be added to the LAN interface. See Secondary IP
Address on page 4-42 for more information.

<Link Speed >

Sets the ethernet PHY mode and speed for the Router.

NOTE: It is highly recommended that this setting be left at auto-negotiation.

Static Networks

Static Networks

Static networks allow fixed, or pre-determined routes, which increases the control over
routing choices within your network. Although Adit units are able to dynamically learn
routing information through RIP packets, you may wish to disable this feature and
manually enter fixed routes. (Disable Learning by choosing the <Neither> option in
the LAN Network Updates field on the Local (LAN) Profile Setup screen.) Static
routing may be preferred if:

 Routers within a network are not configured to advertise, thereby escaping the

automatic learning capabilities of the Adit unit

 Advertising is disabled so that access to certain networks may be restricted for

security purposes or, to decrease traffic on the LAN and across the WAN

 You wish to keep routing tables small in order to increase LAN/WAN

performance

Static routing may also be preferable when managing large networks. Often times it is
easier to disable the learning mode and manually enter routes, rather than review each
routing table entry and determine its advertising status.

As a static routing example, let’s assume that we have three networks, A, B and C.
Network B, is connected to Network C via a router, and to Network A via a remote
Adit. Network B may not learn of Network A’s existence if advertising was disabled
on Router 1. Therefore, if you wish to establish an entry in the routing table indicating
a route between Network B and Network C, you can define a static route on Network B.

Static Networks

To continue with this example, if Network B is not configured to advertise Network C
to Network A, then Network A will not dynamically learn of Network C’s existence. If
you wish to establish a route on Network A to Network C, you must define a static route
on Network A that indicates that Network C may be accessed through remote Adit B.

To set up a static route, you must define the following routing information:

 The address of the network you wish to reach;

 How far away from the local LAN the network is located (in terms of metric

measurement or hops, depending on the protocol)

 Whether the network can be reached on the local LAN (via the LAN port) or

through a remote unit.

If you are using the local LAN, you will also need to define the address (either IP or
MAC, depending on the protocol) of the first gateway (i.e. Adit or router) you will use
to reach the network you are defining.

It is important to note that if the static network is reached via a remote unit, it must be
defined by choosing the SETUP <Static Networks> option on the corresponding
Remote (WAN) Profile Setup screen. Static networks that are reached via the local
LAN must be defined by choosing the SETUP <Static Networks> option on the Local
(LAN) Profile Setup screen.

NOTE: All static routes are considered filters and will be applied toward the
maximum allowable number of 500 filters.

Static Networks

Subnet Mask

A subnet mask determines which bits in the IP address are used to identify the network number.
It is also a method of extending the IP Network Address so that a site may use one network
address for several different networks.

Metric

A numeric value indicating the distance from a local network to the destination network.
Originally this measured by the number of gateways between the two networks, the number may
be modified, either higher or lower, to indicate a desired priority. To ensure a route is considered
primary, the value must be less than that of a secondary route. This field is only used on IP
networks. Range 1 to 15. (Please note that a value of 1 usually indicates a direct network.)

Hops

See Metric, above. When defining the number of hops in a given route, remember to increment
the actual number by 1, since your locally attached unit is counted as “1”. This field is only used
on IPX networks. Range 1 to 15.

Ticks

Indicates the distance between two networks as measured in time increments
(1/18th of a second). Only IPX Networks use this information. Like hops, ticks may be used to
designate primary and secondary routes to the same network. Although both the hops and ticks
values are considered when determining routing priority, for Novell networks, the tick value is
considered first. To designate routing priority between two routes, the preferred tick value will
be lower. Range 1 to 15.

Next Gateway

Enter the IP Address of the first gateway (Adit or router) that the data will use to reach the
destination network. Referring back to Example 1, Network B would enter the IP Address of
Router 1, since that is the first gateway on the route to Network C. This field is only used on IP
Networks.

Next IPX Router

Enter the MAC Address of the next gateway (Adit or router) on the route that the data will use
to reach the destination network. Referring back to Example 1, Network B would enter the
MAC Address of Router 1, since that is the next gateway on the route to Network C. This field
is only used on IPX networks.
