HSIM-W6 Hardware

This section details the HSIM-W6 hardware capabilities.

WAN Connection

The HSIM-W6 supports Point-to-Point Protocol (PPP) including: Link Control Protocol (LCP),
BNCP, IPCP, IPXCP, LQM, Multilink Protocol (MP) and CHAP and PAP, ISDN-BRI and Frame
Relay protocols through one of the following WAN port interface modules (WPIMs):

• The WPIM-T1 provides a T1 interface through a front panel RJ45 port and includes a built-in

Channel Service Unit/Digital Service Unit (CSU/DSU) for direct connection to a T1 line. The
WPIM-T1 provides both Full T1 or Fractional T1 using 56 or 64 Kbps timeslots, with a total
throughput of up to 1.544 Mbps.

HSIM-W6 User’s Guide 5

Chapter 2: About the HSIM-W6

• The WPIM-SY provides a synchronous serial connection of up to 2.048 Mbps to external

communications equipment (e.g., a multiplexer or CSU/DSU). The WPIM-Sync uses a
subminiature 26-pin connector that supports the following electrical signal interfaces (see the

Synchronous WAN Configuration Window section in Chapter 4 for specific cable part

numbers):

• EIA-RS449

• V.35

• EIA-RS232D

• X.21

• EIA-RS530

• EIA-530A

• RS530 AL T A

• RS530A AL T A

• The WPIM-DDS provides a 56 Kbps or 64 Kbps Digital Data Service (DDS) connection. The

WPIM-DDS supports remote CSU diagnostic or 64 Kbps clear channel loopback and
non-latching remote DSU diagnostic loopback.

• The WPIM-E1 provides an E1 interface through a front panel RJ45 port and includes a built-in

CSU/DSU for direct connection to an E1 line. The WPIM-E1 provides both Full E1 or
Fractional E1 using 56 or 64 Kbps timeslots with a total throughput of up to 2 Mbps.

• The WPIM-DI provides a T1 interface through a front panel RJ45 port and includes a built-in

CSU/DSU for direct connection to a T1 line. The WPIM-DI provides both Full T1 or Fractional
T1 using 56 or 64 Kbps timeslots and also provides a second Drop-and-Insert interface, which
allows more than one device to share a single T1 connection.

• The WPIM-S/T provides an Integrated Services Digital Network (ISDN) 128 Kbps Basic Rate

Interface (BRI) for the HSIM-W6. The WPIM-S/T pro vides an ISDN back-up link for a remote
site or branch office when the main WPIM for a frame relay or leased line loses a connection
or becomes disabled. An NT-1 adapter is necessary for this interface in the United States.

• The WPIM-HDSL provides a connection for users in a campus environment, or ha v e access to

local subscriber loops, who want to send their data over their existing telephone lines, that may
run between floors, buildings, or other physical structures, at rates of up to 1.544 Mbps. HDSL
supports line lengths of up to 3, 657 meters (12,000 feet) over 24 AWG (American Wire Gauge)
Unshielded Twisted Pair (UTP) cabling.

6 HSIM-W6 User’s Guide

Chapter 2: About the HSIM-W6

• The WPIM-T1/DDS provides both a T1 and DDS interface that allows you to easily switch

between the two interfaces by changing the physical cabling and reconfiguring QuickSET for
the desired interface. The WPIM-T1/DDS has the capabilities of both the WPIM-T1 and
WPIM-DDS.

Additional Features

FLASH EEPROMs — The HSIM-W6 uses FLASH Electrically Erasable Programmable

Read-Only Memory (EEPROM) that allows the downloading of new and updated firmware in
conjunction with Cabletron Systems QuickSET or any device using BootP or TFTP protocols.

LANVIEW LEDs — Cabletron Systems LANVIEW Status Monitoring and Diagnostics System is

a troubleshooting tool that helps in the diagnosing of power failures, collisions, cable faults, and
link problems. The LANVIEW LEDs are located on the HSIM-W6 front panel.

Remote Management Capabilities

The HSIM-W6 can be remotely managed with any SNMP network management system including
the following:

• Cabletron Systems SPECTRUM

• Cabletron Systems Remote SPECTRUM Portable Management Applications (SPMAs)

• Third party SNMP compliant network management packages

• Cabletron Systems QuickSET

• Cabletron Systems SPECTRUM Element Manager (SPEL)

HSIM-W6 User’s Guide 7

Chapter 2: About the HSIM-W6

Optional Feature

Hardware Data Compression Module (CSX-COMP/ENCR) — The same industry standard

STAC Electronics Stacker LZS Compression algorithm supported by HSIM-W6 software is made
available by an optional hardware data compression module that accelerates data compression for
the HSIM-W6 over PPP and Frame Relay. Depending on the packet type and size, hardware data
compression provides a minimum of 2:1 data compression, giving 3 Mbps throughput on each T-1
WPIM interface. To use the hardware data compression module, compatible equipment (such as
the HSIM-W6, CSX200, and CSX400 or other vendors’ equipment which conforms to the
applicable standards), must be in use at both ends of the WAN link. When the hardware data
compression module is installed on the board, it automatically assumes the compression task from
software. There is no configuration necessary to prioritize hardware over software compression.

HSIM-W6 Firmware Support

The HSIM-W6 firmware supports IEEE 802.1d bridging, and IP and IPX routing, and OSI Layer 2
Inverse Multiplexing (IMUX), which allows both WAN channels to be used as a single, high
bandwidth, WAN channel. Wide Area Networking includes Point-to-Point Protocol (PPP),

Frame Relay, and ISDN. Remote access is via Full or Fractional T1, E1, Synchronous, Digital

Data Service, ISDN BRI, or HDSL connections.
This device supports industry-standard protocols, security features, compression algorithms and

network management tools to ensure interoperability with equipment from other vendors.

WAN Protocols

This device supports the following WAN protocols over the WAN port:

• Point-to-Point Compression Control Protocol (CCP) as defined by RFC 1962

• Point-to-Point Protocol (LCP) as defined by RFC 1661

• Point-to-Point Protocol (BNCP) as defined by RFC 1638

Q.933 Annex A

• Frame Relay Data Encapsulation as defined by RFC 1490

• Frame Relay Data Compression Protocol (DCP) as defined by FRF.9

PPP is a data link layer industry standard WAN protocol for transferring multi-protocol data traffic
over point-to-point connections. With this protocol, options such as security, data compression,
and network protocols can be negotiated over the connection.

Frame Relay is a packet-switching data communications protocol that statistically multiplexes
many data conv ersations o ver a single transmission link. Data compression allows Frame Relay to
negotiate compression over Frame Relay permanent virtual circuits (PVCs)

ISDN BRI is a switched Data Link layer control protocol which uses digital signaling to place a
call into an ISDN network. Once the call is made, PPP is then used to transfer data.

Inverse Multiplexing

NOTE

Cabletron Systems products that support Inverse Multiplexing (IMUX), such as the
HSIM-W6, CSX400, and HSIM-4T1, must exist on both ends of the WAN link for the
IMUX function to work.

Both bridging and routing functions are disabled when using the IMUX function.

Cabletron Systems Inverse Multiplexing (IMUX) feature provides enhanced throughput for users
by doing each of the following:

• The IMUX function evenly distributes a data packet stream from the LAN interface through the

two WAN interfaces on the HSIM-W6. Since the data traffic is equally shared between the tw o
Full T1 interfaces, each with 1.5 Mbps throughput, the total throughput over the logical link is
3 Mbps, or 6 Mbps full-duplex operation with the optional hardware compression module
(CSX-COMP/ENCR) installed in the HSIM-W6.

• The IMUX function passes packet sequence information over the WAN using the Point-to-Point

Protocol (PPP) to support data coherency on both ends of the link.

• Data packet streams received by the WAN interfaces on the other end of the WAN link are then

recombined, ordered, and transmitted to the LAN interface.

• The IMUX function is fully configurable using QuickSET, which is discussed in the Bridging

and Routing Configuration section of Chapter 4 and the MIB Navigator command set

discussed in Chapter 6.

Firmware Data Compression

The STAC Electronics Stacker LZS Compression algorithm provides a minimum of 2:1 firmware
data compression for the HSIM-W6 over PPP and Frame Relay. Firmware data compression is
supported in software on each WAN interface for line speeds of up to 256 Kbps per WPIM, which
is equivalent to four DS0 channels. To use data compression, compatible equipment, (such as the
HSIM-W6, CSX400, and CSX200 or other vendors’ equipment which conforms to the applicable
standards), must be in use at both ends of the WAN link. This firmware method of data
compression is used as the default, if the hardware compression module is not installed.

Chapter 2: About the HSIM-W6

HDLC

Cabletron Systems has provided the High-level Data Link Control (HDLC) protocol which is used
in conjunction with the Inverse Multiplexing (IMUX) feature and the WPIM-HDSL to conserve a
user’s WAN bandwidth between two Cabletron Systems products, over a point-to-point
connection. Cabletron Systems products such as the HSIM-W6, CSX200, and CSX400 must be in
use on both ends of the WAN link for these functions to work. The HDLC (RAW) protocol reduces
the amount of overhead information that needs to be contained within each data packet to direct it
to its destination. This decreased packet overhead provides the IMUX and HDSL functions with
more bandwidth to transfer user data.

DHCP and NAT

The Dynamic Host Configuration Protocol (DHCP) and Network Address Translation (NAT)
method eliminates the expense of purchasing limited public IP addresses for each client on a local
network, and the need to re-configure a client if it is moved to a different network.

The HSIM-W6 acts as a DHCP server that allows individual clients (PCs, network equipment) to
take turns using a range of private IP addresses (often referred to as local IP addresses), and
provides optional secondary setup features for these clients on a per-port basis. The HSIM-W6
distributes these addresses dynamically, assigning a local IP address to an individual client from a
range of 253 available addresses in its table on a first-come-first-served basis. This local IP address
is then “leased” for an predetermined amount of time, which is configured for the particular port.
The Ethernet port provides DHCP services for one Class C subnet and secondary setup features for
individual clients support the use of a default gateway, domain name and WINs server.

On the Wide Area Network (WAN) side, the Network Address Translation (NAT) routing method
is used to enable clients assigned with local IP addresses to use the public IP address(es) of the
HSIM-W6 WAN interface(s) to access the WAN.

NOTE

A private or “local” network is referred to as a sub network that is using private or
“local” IP addresses. An “outside” network refers to a Wide Area Network (WAN)
commonly known as an Internet where registered public IP addresses are required.

HSIM-W6 User’s Guide 11

Chapter 2: About the HSIM-W6

The NAT method allows several DHCP clients on a sub network to connect to WAN clients by
allowing the DHCP clients to share a single public IP address. When the HSIM-W6 uses NAT, the
NAT method modifies the IP headers and addresses, and the selected fields in upper layer protocol
headers. This is done to replace the hidden local IP addresses from the sub network with one or
more public InterNic assigned IP addresses that can be sent over the outside network on the
HSIM-W6 WAN interfaces. Once the HSIM-W6 is assigned at least one public IP address, over
250 IP clients can share this address simultaneously using NAT. This public IP address is assigned
statically by the Internet Service Provider (ISP).

Point-to-Point Protocol

PPP is a data link layer industry standard WAN protocol for transferring multi-protocol data traffic
over point-to-point connections. It is suitable for both high-speed synchronous ports as well as
lower speed asynchronous dial-up ports. With this protocol, options such as security and network
protocols can be negotiated over the connection.

This device supports synchronous PPP over the ISDN port. In Single Link Mode, PPP uses one
ISDN B channel for data transmission. PPP runs over each ISDN B channel for two separate
conversations (split B-channel). In Multi-Link Protocol Mode, PPP simultaneously sends and
receives data over two ISDN B-channels on the same connection to optimize bandwidth usage.

The STAC Electronics Stacker LZS Compression Protocol is supported over PPP providing up to
4:1 data compression.

PAP and CHAP Security

The HSIM-W6 supports the Password Authentication Protocol (PAP) and Challenge Handshake
Authentication Protocol (CHAP) under PPP.

PAP provides verification of passwords between devices using a 2-way handshake. One device
(peer) sends the system name and password to the other device (authenticator). Then the
authenticator checks the peer’s password against the configured remote peer’s password and
returns acknowledgment.

CHAP is more secure than PAP as unencrypted passwords are not sent across the network. CHAP
uses a 3-way handshake and supports full or half-duplex operation.

12 HSIM-W6 User’s Guide

Chapter 2: About the HSIM-W6

In half-duplex operation, the authenticator device challenges the peer device by generating a
CHAP challenge, and the challenge contains an MD5 algorithm with a random number that has
your encrypted password and system name. The peer device then applies a one-way hash
algorithm to the random number and returns this encrypted information along with the system
name in the CHAP response. The authenticator then runs the same algorithm and compares the
result with the expected value. This authentication method depends upon a password or secret,
known only to both ends locally.

Full-duplex operation places an additional step to the half-duplex operation that mirrors the
operation discussed above for a peer to validate the authenticator. The peer device challenges the
authenticator by generating a CHAP challenge, and the authenticator returns a CHAP response.

The peer device challenges the authenticator device by generating a CHAP challenge, and the
challenge contains an MD5 algorithm with a random number that has your encrypted password
and system name. The authenticator device then applies a one-way hash algorithm to the random
number and returns this encrypted information along with the system name in the CHAP response.
The peer device then runs the same algorithm and compares the result with the expected value.
This authentication method depends upon a password or secret, known only to both ends locally.

LQM

Link Quality Monitoring (LQM) is a link control mechanism used with PPP to determine when
and how often a link is dropping data in units of packets and octets. Link Quality Monitoring
accomplishes this by providing Link-Quality-Reports to determine if the quality of the link is
adequate for operation. Link Quality Monitoring provides separate measurements for both
incoming and outgoing packets that are communicated to both ends of the link. The PPP LQM
mechanism carefully defines the Link-Quality-Report packet formats, and specifies reference
points for all data transmission and reception measurements. The LQM implementation maintains
successfully received packet and octet counts, and periodically transmits this information to its
peer using Link-Quality-Report packets.

Multilink Protocol

Multilink Protocol (MP) is an extension of PPP that controls the way frames are transferred across
several links whenever a single link is not sufficient to meet the requirements of your present
traffic load. Multilink Protocol establishes sev eral simultaneous links between two end points o v er
switched circuits (dial-up lines) in an ISDN network, and dynamically adjusts the bandwidth
demands between available links to maintain an effective data transfer.

ISDN

ISDN provides an inexpensive switched digital access to remote sites. The ISDN BRI standard
provides for two high speed 64 Kbps bearer (B) channels used for voice or data connections and
one 16 Kbps signaling data (D) channel used for call setup, signaling and other information. ISDN
allows all types of information to be transmitted including voice, data, fax and video. Multiple
devices can be linked to a single ISDN connection, each having their own telephone number. Two
or more channels can be combined into a single larger transmission pipe offering variable
transmission speeds.

The HSIM-W6 supports one ISDN BRI line and either or both of the B channels for transferring
data. If the two B channels are used for separate connections, each provides up to 64 Kbps transfer
rates. Both channels can be used together to provide uncompressed data transfer at up to 128 Kbps.
The HSIM-W6 can also transfer compressed data at up to 512 Kbps.

A Network Terminator device (NT1) provides the interface between ISDN terminal (router)
equipment and the ISDN service provider. In the U.S., the NT1 is provided by the customer;
outside the U.S., the NT1 is provided by the ISDN service provider. The HSIM-W6 supports the
WPIM-S/T that provides an S/T interface requiring an external NT1.

Telephone Switch Support

The following telephone switch types are supported within the U.S.:

• National ISDN 1 (NI-1)

• AT&T 5ESS w/Custom Software

ISDN Back-up

The ISDN back-up feature provides a back-up link for a remote site or branch office when one or
more primary WAN interfaces for a frame relay circuit or a nailed-up PPP connection fails. The
WPIM-S/T serves as the backup medium for this primary connection. The WPIM-S/T uses the
ISDN interfaces to back-up any primary interfaces which hav e been configured for ISDN back-up.

Time to Connect, Time to Disconnect, Connect Retries, Back-up Override, Input Idle Time-out
and Output Idle Time-out, are the six back-up parameters used to manage the ISDN Back-up
feature on the HSIM-W6, and are described as follows:

Time to Connect — Time to Connect allo ws you to configure the amount of seconds the primary

interface can be in a failed state, before attempting to switch over to the back-up interface.

Time to Disconnect — Time to Disconnect allows you to configure the amount of seconds the

restored primary interface must remain connected, before attempting to switch over from the
back-up interface.

Connect Retries — Connect Retries allows you to configure the number of tries to restore the

back-up interface, before giving up.

Backup Override — Backup Override forces the back-up interface to remain connected, and

does not allow the back-up interface to switch back to the primary interface, even if the primary
interface is restored.

Input Idle Time-out — Input Idle Time-out allows you to determine the amount of time necessary

for data packets to be received, before the interface is automatically disconnected.

Output Idle Time-out — Output Idle Time-out allows you to determine the amount of time

necessary for data packets to be transmitted, before the interface is automatically disconnected.

HSIM-W6 User’s Guide 15

HDSL

High-bit rate Digital Subscriber Line (HDSL) technology uses existing copper twisted pair cables
designed for conventional analog voice transmission from a telephone carrier servicing area as a
low-cost alternative to the quality and speed of fiber optic cables, and provides high-speed
full-duplex digital transmission links of up to 1.544 Mbps. The WPIM-HDSL is easy to install in
your network over existing telephone lines, and it is a portable investment if a business, or
individual user plans to relocate.

HDSL is a direct connection technology that allows connections to be made for distances of up to
12,000 feet over 24 American Wire Gauge (AWG) unconditioned Twisted Pair wire. To obtain the
Full T1 line Rate of 1.544 Mbps, two wire pairs are necessary (four wires). If one pair of wires is
used (two wires), then data rates of 772 Kbps are supported, which is equivalent to one-half of a
T1 line.

Bridging and Routing

Bridging — Bridging connects two or more separate networks together. The bridge examines a

portion of each network frame called the header. This header contains control information for the
frame. The bridge compares the destination address of the frame to a table of source addresses
(bridges dynamically learn the physical location of devices by logging the source addresses of
each frame and the bridge port the frame was received on in the source address table). In
transparent bridging, the decision to forward the frame is based on this comparison. If the address
indicates that the sending station and the destination station are on the same side of the bridge, the
frame is not forwarded across the bridge. If the addresses do not indicate that, the bridge forwards
the broadcast frame across the bridge to the other network(s).

Bridging allows frames to be sent to all destinations regardless of the network protocols used. It
also allows protocols that cannot be routed (such as NETBIOS) to be forwarded, and optimizes
internetwork capacity by localizing traffic on LAN segments. A bridge extends the physical reach
of networks beyond the limits of each LAN segment. Filters can be used to increase network
security in bridged networks, and restrict message forwarding by using user-built address
tables (non-transparent bridging).

16 HSIM-W6 User’s Guide

Chapter 2: About the HSIM-W6

Routing — Routing provides a way to transfer user data from source to destination over different

LAN and WAN links using one or more network protocol formats. Routing relies on routing
address tables to determine the best path for each packet. Routing tables can be seeded (i.e.,
addresses for remote destinations are placed in the table along with network address masks and a
metric for path latency). Routing tables are also built dynamically (i.e., the location of remote
stations, hosts and networks are updated through inter-router protocols). Routing helps to increase
network capacity by localizing traffic on LAN segments and broadcasts that would result from
bridged traffic. It also provides security by isolating traffic on segmented LANs. Routing extends
the world-wide reach of networks.

HSIM-W6 Bridging and Routing — The HSIM-W6 can operate as a bridge, a router, or both.

The HSIM-W6 operates as a router for network protocols that are supported when routing is
enabled and operates as a bridge when bridging is enabled. When both bridging and routing are
enabled, routing takes precedence over bridging (i.e., the HSIM-W6 uses the protocol address
information of the packet to route the packet to the correct destination, and if the protocol is not
supported, the device uses the MAC address information to bridge the packet).

Operation of the HSIM-W6 is influenced by routing and bridging controls and filters set during
HSIM-W6 configuration. General IP routing, and routing or bridging from specific remote routers
are controls set during the configuration process.

IEEE 802.1d Bridging — The HSIM-W6 supports the IEEE 802.1d standard for LAN to LAN

bridging. This bridging algorithm learns the low-level MAC addresses of each LAN constituent
and uses this information to decide whether to transmit the packet to another LAN via a WAN
connection, or keep it local. Part of the bridging standard used, called Spanning Tree Protocol,
supports multiple, redundant paths for LAN to LAN bridging, yet prevents data loops and
duplication. This adds fault tolerance to a system of LANs, since, if one WAN data path fails,
another may be substituted automatically.

IP Routing — IP routing support provides the ability to process TCP/IP frames at the network

layer for routing. IP routing support includes the Routing Information Protocol (RIP) that allows
the exchange of routing information on a TCP/IP network. The HSIM-W6 recei ves and broadcasts
RIP messages to adjacent routers and workstations.

IPX Routing — Internet Packet Exchange (IPX) routing support provides the ability to process

Novell proprietary frames at the network layer for routing. IPX routing support includes the
Routing Information Protocol (RIP) that allows the exchange of routing information on a Novell
NetWare network.

Chapter 2: About the HSIM-W6

Bridging and Routing Protocol Filtering

Filtering is used to allow efficient usage of network resources and provide security for your
network and hosts.

IP Internet Firewall — The HSIM-W6 supports IP Internet Firewall filtering to prevent

unauthorized access to your system and network resources from the Internet or a corporate
Intranet. Security can be configured to permit or deny IP traffic. The security is established by
configuring IP access filters, which are based on source IP address, source mask, destination IP
address, destination mask, protocol type, and application port identifiers for both the Transmission
Control Protocol (TCP) and User Datagram Protocol (UDP). These IP access filters allow
individual IP source and destination pair filtering as well as IP address ranges and wild carding to
match any IP address. These Firewall filters can be defined to allow inbound only, outbound only,
or bi-directional IP communication up to the UDP and TCP application port level. Firewall access
filters provide a lot of flexibility to establish a powerful IP security barrier.

The HSIM-W6 supports the IP Access Control (from the ctip-mib) Internet Firewall Filter.

Bridge Filtering — Bridge filtering allows a network administrator to control the flow of pack ets

across the HSIM-W6. Bridge filtering can be used to “deny” or “allow” packets based on a
“matched pattern” using a specified position and hexadecimal content within the packet. This
enables restricting or forwarding of messages based on address, protocol, or data content.
Common uses include preventing access to remote networks, controlling unauthorized access to
the local network, and limiting unnecessary traffic.

The HSIM-W6 supports the following Bridge Filters:

• dot1d.Static Filters (IETF RFC1493)

• Ethernet Special Filtering Database (from the ctbridge-mib)

System Passwords

System passwords allow you to control access to the HSIM-W6 by establishing three passwords.
Each password provides varying levels of access to the HSIM-W6. The default password for each
access level is preset to public.

The following definitions explain each of the three levels of access:

read-only — This access level allows reading of device parameters not including system

passwords.

18 HSIM-W6 User’s Guide

Chapter 2: About the HSIM-W6

read-write — This access level allows editing of some device configuration parameters not

including changing system passwords.

super-user — This access level allows full management privileges, allowing you access to

QuickSET.

Simple Network Management Protocol (SNMP)

The HSIM-W6 provides SNMP agent support for the following: standard and Enterprise Specific
Management Information Bases (MIBs), and support for standard and Enterprise Specific SNMP
Traps. SNMP is also used internally for configuration of the HSIM-W6. The active SNMP agent
within the HSIM-W6 accepts SNMP requests for status, statistics and configuration updates.
Communication with the SNMP agent occurs over the LAN or WAN connection. Any
management application using SNMP over UDP/IP has access to the local SNMP agent.

SNMP MIB Support

SNMP MIBs are databases of objects used for managing and determining the status and
configuration of an SNMP compliant device.

The following SNMP MIBs are supported by the HSIM-W6:

• MIB IIRFC1213

information. It contains the following sections:

• Arranging ISDN Service

• Telephone Switch Support

• ISDN BRI Line Configuration

• SPIDs, Directory Numbers and Telephone Numbers

• Telephone Switch Parameters

Read the first section in this chapter for an overview of the steps required to order ISDN service
from your service provider (telephone company). The rest of the chapter details the information
that the service provider needs to give you, and which you need to give to the service provider.

ISDN Line Ordering and Configuration

Arranging ISDN Service

The service provider requires certain information about the capabilities of the HSIM-W6. You
must give the service provider the required switch settings (parameters) for the provider’s central
office switch. Consult with your service provider at least two months before you require the
installation and use of the ISDN service.

Complete the following steps to arrange your ISDN service:

1. Contact the service provider and determine what type of ISDN central office switches are

available (see Telephone Switch Support in this chapter).

2. Supply the service provider with the provisioning information for their switch type to enable

proper configuration of the ISDN line (see Telephone Switch Parameters in this chapter).

3. Once the ISDN line is installed, ensure that the service provider supplies you with the following

information:

• ISDN telephone numbers

• ISDN Service Profile Identifier numbers (SPIDs) and/or Directory Numbers (DNs) (see

SPIDs, Directory Numbers and Telephone Numbers in this chapter).

HSIM-W6 User’s Guide 23

Chapter 3: ISDN Line Ordering and Configuration

Telephone Switch Support

Your telephone company may offer a variety of ISDN switch types. You must contact your service
provider and find out which type of ISDN service is available.

The following switch types are currently supported by the HSIM-W6 within the U.S.:

• National ISDN 1 (NI-1)

• AT&T 5ESS with Custom Software

• DMS-100

Outside of the U.S. the following switch types are currently supported:

• NET3 (European ISDN)

• NET3SW (European Swiss-variant)

• NTT (Nippon Telegraph and Telephone)

• KDD (Kokusai Denshin Denwa Co., Ltd.)

• French Delta (VN4) switches

ISDN BRI Line Configuration

You need to order one Basic Rate Interface (BRI) ISDN line from your service provider. The Basic
Rate Interface ISDN line provides two full duplex 64 (Kbps) B channels used for voice, data, fax,
etc. and one full duplex 16 Kbps channel used for signaling. Each B channel can be used for a call;
i.e., two calls can occur at the same time. Services vary from individual service providers.

NOTE

The service provider requires some information from you about your configuration. You must
provide your service provider with the required switch settings for the provider’s telephone switch
(see Telephone Switch Parameters in this chapter). Consult with your service provider at least
two months before requiring the installation and use of the ISDN service.

24 HSIM-W6 User’s Guide

Full 64 Kbps for each channel (called clear channel) may not be available across the
entire communications link. Today, many providers still use in-band signaling
(the 8 Kbps signaling is taken from the B channel bandwidth) so that you may only
achieve a 56 Kbps channel speed.

Chapter 3: ISDN Line Ordering and Configuration

In the U.S. and Canada, Network Terminator equipment (NT1) is required to provide an interface
between the HSIM-W6 and the ISDN line. The NT1 offers conversion between the two-wire
twisted pair (U-loop interface) used by telephone companies and the four-wire terminal equipment
(S/T Interface) as well as line-testing capabilities. External Network Terminator equipment comes
with a power supply (built-in or external).

In Europe and Japan, the telephone company provides the NT1 and offers end-users the S/T
interface. The S refers to a connection between customer equipment in some ISDN configurations
when a PBX is present. The T refers to the connection between the NT1 de vice and the HSIM-W6.

The ISDN pairs are the same wires that exist for analog telephone service. In most cases, the same
wires can be used for the ISDN line. The EIA/TIA standard for wiring is Unshielded Twisted Pair
(UTP) cable, Category 3 or above, 24 AWG (American Wire Gauge). The standard also
recommends using 8-position RJ45 jacks for new ISDN service installation. No special
conditioning is required; in some cases, conditioning must be removed.

ISDN BRI Configurations

ISDN BRI lines can be configured in point-to-point and multi-point configurations. With a
point-to-point configuration, only one device is connected to the ISDN line. With a multi-point
configuration, it is possible to have up to 8 devices (telephones, faxes, routers, etc.) connected to
the line.

Since the ISDN BRI line is used for a high speed LAN-to-LAN link, you must ensure that
additional devices connected to the S/T interface allow sufficient access for the bandwidth
requirements of the HSIM-W6.

SPIDs, Directory Numbers and Telephone Numbers

The service provider gives you up to three sets of numbers for identifying the ISDN line and
devices. You may be assigned none, one or two Service Profile Identifier numbers (SPIDs) or
Directory Numbers (DNs) depending on the service provider and country.

Phone Numbers

Numbers used for others to dial into the ISDN B channels on your ISDN line (similar to analog
line phone numbers).

Directory Numbers

Address assigned by the ISDN service provider for each device operating on the line. This number
can be similar to the phone number. The Directory Number is not generally implemented outside
the U.S.

HSIM-W6 User’s Guide 25

Chapter 3: ISDN Line Ordering and Configuration

Service Profile Identifiers

SPIDs, also assigned by the ISDN service provider, identify the services and features that the
telephone company switch provides to the ISDN device. Commonly implemented in the U.S. and
Canada, the SPID is often derived from the directory number, combined in a series with other

Planning for HSIM-W6 ISDN Configuration

This chapter explains the HSIM-W6 ISDN-BRI configuration process and terminology. It also
describes the information that is required for configuration.

Configuration Process and Terminology

During configuration, you specify information identifying the HSIM-W6 and define the LAN and
WAN connections of the HSIM-W6. All of the remote routers to which this device may connect
are added to a database called the remote router database that resides in the HSIM-W6. Each
remote router entry in the database defines the connection parameters, security features, route
addressing and bridging function for the remote router (see the example in Figure 2). Routing and
bridging are controlled by specific remote router entry information as well as general controls that
are set after all other information is configured.

Chapter 4: Planning for HSIM-W6 ISDN Configuration

Collect Network Information

Before you begin, you need to obtain information about the network to which you are adding the
HSIM-W6. Some of the information is obtained from your central site or remote site network
administrator. Other information is obtained from your ISDN service provider.

You must define the name and security password of the HSIM-W6, ISDN line information and the
Ethernet LAN IP and/or IPX address. You need to identify all of the remote routers and their
routing and bridging capability, ISDN phone numbers, addressing and security information. You
also need to decide whether you will use Internet Firewall Filtering if you are using IP routing. The
following sections contain diagrams and tables to help you gather and organize the information.

Names and Passwords

You must choose a name for the HSIM-W6 and the authentication password, both of which are
used by a remote site to authenticate the target router. For each remote router, you must have the
router name and its authentication password which is used by the HSIM-W6 to authenticate the
remote router. The name and password are used in both PAP and CHAP authentication. Figure 3
shows how this information is used.

Chapter 4: Planning for HSIM-W6 ISDN Configuration

ISDN Line Information

You need to know the telephone switch type and phone numbers associated with the ISDN line.
The telephone switch types supported are listed in Telephone Switch Support. The service
provider gives you up to three sets of numbers for identifying the ISDN line and attached devices.
You may be assigned none, one or two SPIDs or DNs and this varies by service provider and
country.

Phone Numbers — Numbers used for others to dial into the ISDN B channels on your ISDN line

(similar to analog line phone numbers).

Directory Numbers — Address assigned by the ISDN service provider for each device operating

on the line. This number can be similar to the phone number. The Directory Number is not
generally implemented outside the U.S.

Service Profile Identifications — SPIDs, also assigned by the ISDN service provider, identify

the services and features that the switch provides to the ISDN device. Commonly implemented in
the U.S. and Canada, the SPID is often derived from the directory number, combined in a series
with other digits as shown in the example in Figure 4. SPIDs are not generally implemented
outside of the U.S. and Canada.

Network Information Diagrams

It is helpful to draw a diagram including all locations, addresses, router names, etc. This section
includes diagrams needed to configure the HSIM-W6. You may need different addressing
information depending on whether you are configuring IP routing and/or NetWare IPX routing.

NOTE

to configure both ends of the WAN link, you should label all information for the network.

TCP/IP Routing — An IP address and subnet mask are required for the Ethernet LAN for the

router connection. Each remote router ISDN WAN link may have local and remote IP addresses
and subnet masks depending on the type of IP addressing as shown in Figure 5. The IP routing
table in the HSIM-W6 can be “seeded” with addressing information for networks/stations beyond
the remote router.

Chapter 4: Planning for HSIM-W6 ISDN Configuration

TCP/IP Route Addresses — If the HSIM-W6 is to direct traffic to networks or stations beyond

the remote router, the routing table in the HSIM-W6 can be “seeded” with static IP routes. An IP
route includes an IP address, subnet mask and metric. The metric is a number representing the
perceived cost in reaching the remote network or station.

The HSIM-W6 routing table must be seeded statically so that it dials out to the appropriate remote
router when IP traffic is targeted to networks and stations be yond that remote router. After the link
is established, RIP update packets are dynamically added to the routing table. Seeding the routing
table is not necessary when the HSIM-W6 never dials out; it discovers remote networks and
stations beyond the calling router as soon as RIP updates arrive (provided the remote router
supports RIP and RIP packets are allowed to flow on the WAN link).

TCP/IP Default Route — One default route should be designated in the routing table for all

traffic that cannot be directed to other specific routes. You need to define the default route for a
remote router if the HSIM-W6 will be placing calls to that remote router.

Source (Target) and Remote WAN IP Addresses — You may need to specify a Source WAN IP

address and/or a Remote WAN IP address for the WAN connection to the remote router depending
on IP address negotiation under PPP. Check with your system administrator for details on whether
the router must communicate in numbered or unnumbered mode and what addresses are required.

In unnumbered mode, neither IP address is defined on the link. In numbered mode, one IP address
is defined on each end of the WAN link. These addresses may or may not belong to the same
subnetwork. They may also be determined automatically, negotiated, or forced by the network
administrator.

The HSIM-W6 automatically determines whether to run in unnumbered mode or numbered mode.
If unnumbered mode negotiation fails, numbered mode is attempted using the Ethernet LAN IP
address as a default. If you have specified a Source WAN IP address, unnumbered mode
negotiation is not performed; i.e., the operating mode is numbered. If a Source WAN IP address is
explicitly defined, the router will not, as a rule, accept another local address from the remote end.
In numbered mode without an explicit Source WAN IP address, this address can be negotiated to a
different value by the remote end.

HSIM-W6 User’s Guide 33

Chapter 4: Planning for HSIM-W6 ISDN Configuration

If the remote router supports unnumbered mode, neither address needs to be specified. Figure 6
provides a simple example of an unnumbered mode configuration.

For numbered mode, consider the capabilities of the remote router as well as your requirements.
Specify a Source WAN IP address if the HSIM-W6 must be on the same subnetwork as the remote
router. Figure 7 is an example of a Class B IP network (128.1).

NetWare IPX Routing — An Ethernet LAN IPX network number is required for the HSIM-W6

local Ethernet LAN connection. The ISDN WAN link to each remote router must hav e an assigned
IPX network number. IPX Routes and IPX SAPs for each remote router are also required for the
configuration process. Figure 9 provides an example of the network layout for IPX routing.

Chapter 4: Planning for HSIM-W6 ISDN Configuration

IPX Routes — If the HSIM-W6 is to direct traffic to network segments and servers beyond the

remote router, the routing table in the HSIM-W6 can be “seeded” with static IPX routes. An IPX
route includes a network number, hop count and ticks. The hop count is the number of routers
through which traffic must pass to reach the remote network segment or server. Ticks represent
how much time the packet takes to reach the destination in roughly 1/18th of a second increments.

The HSIM-W6 routing information table must be seeded statically so that it dials out to the
appropriate remote router when IPX traffic is targeted to network segments or servers beyond that
remote router. After the link is established, RIP update packets dynamically add to the routing
information table in the HSIM-W6. Seeding the routing table is not necessary when a HSIM-W6
never dials out; it will discover routes beyond the calling router as soon as RIP updates arrive
(provided the remote router supports RIP).

IPX SAPs — If the HSIM-W6 is to obtain services beyond the remote router, the HSIM-W6 SAP

services table must be seeded statically. A SAP service is identified by a server name and
corresponding server type, network number, node number and socket. The socket number
represents the service (application) within the server node.

The HSIM-W6 SAP services table must be seeded statically so that the device can direct traffic to
the appropriate remote router when a service is requested from a server beyond that remote router.
After the link is established, SAP broadcast packets dynamically add to the target router services
table. Seeding the table is not necessary when a HSIM-W6 never dials out; it will discover remote
services beyond the calling router as soon as SAP broadcasts arrive (provided the remote router
supports IPX).

IPX Network Numbers — IPX network numbers are assigned to LAN network segments as well

as servers. These numbers should be unique for all IPX networks on the Internetwork.
IPX external network numbers refer to the physical LAN network segments to which servers and

routers are connected. The WAN link network number is an external IPX netw ork number. This is
a unique number that you choose (or are given by the network administrator) to represent the WAN
link between the HSIM-W6 and remote router. The local Ethernet IPX network number is also an
external network number.

Servers are identified with internal network numbers. This is a logical network number that
identifies the individual server. For a local router to access a server beyond the remote router, you
specify a route using the internal network number of a server. To seed the routing table to access a
network segment, you specify the external network number of the LAN segment. The network
number in the SAP table is the internal network number of the server.

HSIM-W6 User’s Guide 37

Chapter 4: Planning for HSIM-W6 ISDN Configuration

Node Numbers — Servers can have internal and external node numbers. The internal node

number is a logical number assigned by the system administrator to the server. The external node
number is the MAC address of the server. When adding SAP services to the SAP table, internal
node numbers are used.

Network Information Tables

The following tables list the items you need to define or obtain to configure the router. This
information is illustrated in the network information diagrams and described in the previous
sections. Worksheets are provided in Appendix C, so that you can enter details about your
HSIM-W6 and remote routers. Table 4 provides information for configuring your system settings,

Table 5 explains the Remote Router Database configuration settings and Table 6 details bridging

and routing configuration.

NOTE

Names and Passwords Example

In the sample configuration provided in Table 11, a small office FP2 communicates with a central
site FP3 and an Internet Service Provider ISP. As indicated in this example, router FP2 has a
system password “FP2passwd”. This password is used when FP2 dials out to site FP3 for
authentication by that site, and at any time when FP3 challenges FP2. FP3 has a system password
“FP3passwd” which is, likewise, used when FP3 dials out to site FP2 for authentication by FP2,
and at any time FP2 challenges FP3. The ISP site has a system password “ISPpasswd” used for the
same purpose.

Each router includes the remote router password in the definition of any remote site to which it
communicates. The router will use the remote password to authenticate the remote site when the
remote router dials in or is challenged by the local site. For example, FP2 has remote router entries
for FP3 and ISP, and defined in each entry are the respective remote router password.

The following table shows the names and passwords for each router that must be defined for
authentication to be performed correctly. (This assumes that all three systems use some form of
authentication protocol.)

you click on the Next>> button in the (T1, E1, or DI) Wide Area configuration window and Frame
Relay is chosen as the WAN Protocol.

Figure 28 Wide Area Frame Relay Time Slot Configuration Window

The following section defines the field in the Wide Area Frame Relay Time Slot configuration
window.

Time Slots — A full line consists of 24 Time Slots (T1, D1) or 31 Time Slots (E1), each capable

of up to 64 Kbps throughput. If you are leasing an entire line from your service provider, you may
select all of the Time Slots by clicking on each one. A “check mark” displays in the selected box.

82 HSIM-W6 User’s Guide

Chapter 6: HSIM-W6 Configuration with QuickSET

If you have leased a portion of a fractional line (T1 or E1), the service provider tells you which
Time Slots are allocated for your use. In this case select only those Time Slots.

NOTE

If you are configuring a WPIM-DI Time Slot table, any available Time Slots that are not
checked are mapped to the DI Interface. In other words, if you lease an entire T1 line,
any Time Slots that are not selected in the Time Slot configuration window are used by
the device connected to the DI interface.

Once the Frame Relay Time Slot configuration is complete, click on Next>> in the Frame Relay
Time Slot configuration window and proceed to the Bridging and Routing Configuration
section.

The following section defines the field in the Wide Area PPP Time Slot configuration window.

Time Slots — A full line consists of 24 Time Slots (T1, D1) or 31 Time Slots (E1), each capable

of up to 64 Kbps throughput. Using the PPP Protocol, up to 24 interfaces (T1, D1) or 31 interfaces
(E1) can be assigned to the WAN link. Using the pull-down menu to the right of each Time Slot
field, select the interface number that you wish to assign to the Time Slot.

NOTE

NOTE

If you are configuring a WPIM-DI Time Slot table, any available Time Slots that are not
set to “0” will be mapped to the DI Interface. In other words, If you lease an entire T1
line, any Time Slots that are not used in the Time Slot configuration window are used
by the device connected to the DI interface.

The interface numbers available in the pull-down menu are assigned in the WAN (T1,
E1, DI) configuration window. Selecting the Add Interface button or the Delete
Interface button allows you to add or delete available interface numbers from each
pull-down menu.

Once the PPP Time Slot configuration is complete, click on Next>> in the PPP Time Slot
configuration window and proceed to the Bridging and Routing Configuration section.
