1

This guide is intended to aid the configuration of a unit in a number
of common circumstances. It assumes that the reader is familiar with
basic networking terminology and techniques and has read the
Internetworking Concepts Guide.

Requirements

Before attempting any configuration of the unit, the IP address (and
subnet mask) of the local area network and the ISDN number of the
unit must be known.

The unit must be powered-up and connected to a correctly functioning
ISDN line, using the supplied cable, following the instructions given in
the unit’s Installation Guide.

Management System Commands

The commands in this guide are always shown in upper-case letters
(for clarity) but they can be entered in either upper- or lower-case
with the exception of passwords and unit names. These are
case-sensitive and must be entered correctly. The default password
for a unit in factory standard configuration (PASSWORD)
entered in upper-case letters only.

Unit Naming Convention

Throughout this guide the text uses the convention of “central site
unit” to represent a unit situated on a network at a larger branch or
regional office, to which a number of units may connect using
dial-up ISDN links. The text refers to these latter units as “remote site
units”, which are likely to be situated in smaller offices.

“One-to-one” Configuration

In situations where a very simple connection is required between two
units only, it is recommended that one unit is nominated as the
“central site” (configured first) and the other as the “remote site”
(configured second), following the relevant sequence for each.

Leased Lines

It is good practise that the WAN port of an existing installation which
has already been configured for bridging or routing, and has an
additional fixed-link serial line (sometimes called a “Kilostream” line)
connected to the WAN port, should be disabled prior to the new
configuration.

Take a note of the current WAN port configuration parameters
before disabling the port and keep it in a safe, accessible place

1

Enter CO PO to display the Port Configuration screen.

2

Select the WAN port using the Arrow keys.

3

Enter TY NO to disable the WAN port

4

Enter

SAVE

to save the new configuration.

New installations and those units which have been reset to the
factory default configuration have their WAN ports disabled.

Configuration by Telephone

It is possible to connect a standard telephone handset to units which
are fitted with a Voice port. This is a useful configuration aid for units
which have been correctly installed and connected to a functioning
ISDN line. A telephone connected to a central site unit Voice port can
dial the ISDN number of the remote site unit and connect to a
telephone plugged into the remote site unit Voice port. This
connection allows an experienced technician to guide a
less-experienced technician through the configuration steps of the
remote site unit.

This chapter shows how to configure units to operate as bridges,
using the Internet Protocol (IP) data packets between two networks
for management and control only.

Configuration steps are given for:

■ Manual configuration of the central site unit.

■ Quick Configuration of the remote unit.

■ Remote configuration of the remote unit from the central site.

Bridging and IP

It is essential to remember that a bridged network using IP for
management only, even if it consists of several segments, always has
the same IP network address for each segment. If any segment of the
network has a different IP network address, then data must be
routed to and from that network segment.

Configuration Options

When configuring a unit to bridge IP packets using a dial-up ISDN
link between a central site and one or more remote sites, it is
recommended that the central site should be configured manually
first.

The central site unit cannot be automatically configured using the
Quick Configuration facility of the unit because this facility requires a
ready-configured unit to act as a reference point.

The Quick Configuration facility should only be used at a remote site.

Outline of Configuration Procedure

The steps below are intended as an outline of the sequence for
configuring a unit for bridging and IP. They are for guidance only and
must be used in conjunction with the full description given in the
following pages.

There are five basic steps for manual configuration of a unit for
bridging and IP. The sequence for remote configuration of a unit
necessitates a similar sequence with additional steps. The additional
steps are given in “Configuring a Remote Unit from the Central Site”
on page 2-8. The Quick Configuration facility has three steps.

The five basic steps for manual configuration are:

■

Assign a unique name to the unit.

■

Configure a unique IP address for the unit.

■

Configure the ISDN network type, if required.

) of the central site unit.

It is very important to assign a unique name and IP address to each unit.

■

Set up the ISDN Numbers table to associate a remote unit name
with an ISDN number.

■

Make an entry in ISDN Autocall table to associate a unit IP address
with a remote unit name.

The three Quick Configuration steps are:

■

Assign the unit name, configure the unit IP address and the ISDN
network type (if required).

■

Specify the ISDN number of the central site unit.

■

Make a manual call to the central site unit, if required.

Quick Configuration of the remote router.

■

Remote configuration of the remote router from the central site.

Routing IP

If data is required to be shared or transferred between IP networks
with different network numbers or subnets, the IP protocol cannot
be bridged and has to be routed.

Configuration Options

IP

When configuring a unit to route IP packets using a dial-up ISDN link
between a central site and one or more remote sites, it is
recommended that the central site should be configured manually first.

The central site unit cannot be automatically configured using the
Quick Configuration facility, because this facility requires a
ready-configured unit to act as a reference point.

The Quick Configuration facility should only be used at a remote site.

Alternatively, the remote site unit can be configured by utilizing the
remote configuration facility (REM) of the central site unit.

Outline of Configuration Procedure

The steps below are intended as an outline of the sequence for
configuring a unit for bridging and IP. They are for guidance only and
must be used in conjunction with the full description given in the
following pages.

There are seven basic steps required for manual configuration of a
unit for routing IP. The sequence for remote configuration of a unit
necessitates a similar sequence with additional steps. The additional
steps are given in “Configuring a Remote Unit from the Central Site”
on page 3-9. The Quick Configuration facility has three steps.

The seven basic steps are:

■

Assign a unique name to the unit.

■

Configure the IP address and subnet mask for the unit.

It is very important to assign a unique name and IP address to each unit.

■

Configure the ISDN network type, if required.

■

Set up the ISDN Numbers table to associate a remote unit name
with an ISDN number.

■

Set up the ISDN Autocall table to associate a unit IP address with
a remote unit name.

■

Set up the IP Routing table to associate an IP route with a unit
name.

■

Enable IP routing.

The three Quick Configuration steps are:

■

Assign the unit name, configure the IP address, a valid network
subnet mask and the ISDN network type (if required).

■

Specify the ISDN number of the central site router.

■

Make a manual call to the central site router.

■

Unit name (see page 3-4).

■

A valid IP address, subnet mask and hop count (see page 3-4).

■

The correct ISDN network type (see page 3-4).

Novell IPX Bridging

Novell Netware® has a software router built into the Novell server
that leads to an internal network which links the file server and other
services. The presence of this internal software router means that a
Novell Netware network can never be an entirely bridged network,

The five basic steps are:

■

Assign a unique name to the unit.

■

Configure a unique, valid IP address for the unit.

It is very important to assign a unique name and IP address to each unit.

■

It is good practise to configure a valid subnet mask for the unit.
Although this step is not absolutely necessary, it is recommended.

Set up the ISDN Numbers table to associate a remote unit name
with an ISDN number.

The Quick Configuration steps are:

Configuring a Remote Unit from the Central Site

A unit at a remote site can be remotely configured for IPX and bridging.
The remote management and configuration capability allows the unit to
be configured from the central site, without the need for a technician to
travel to a remote site.

It is good practise to have ensured that the remote unit was restored
to the factory default settings before being despatched to the
remote site.

Prior to Despatch

Power on the unit and follow the sequence of steps for resetting the
unit to the factory default configuration, as described in

“Configuring a Central Site Unit for Routing IPX” on page 5-2.

Configure the ISDN network type to the correct setting for the
remote site, following the sequence of steps described in “Configure

the ISDN Network Type” on page 5-4.

When the unit is received at the remote site, ensure that it is
powered on and that the ISDN Port is connected to a correctly
functioning ISDN line, using the supplied ISDN cable.

Configuring the Central Site Unit

The central site unit must be correctly configured with the following
parameters:

■

Unit name (see page 5-3).

■

A valid IP address and subnet mask (see page 5-4).

■

The IPX network number (see page 5-4).

■

The IPX frame type (see page 5-4).

This chapter gives the basic steps for configuring a simple
Point-to-Point Protocol (PPP) connection to an Internet Service
Provider (ISP). Configuring a PPP connection using numbered links is
a complex procedure and should only be attempted by experienced
networking technicians. The configuration is not covered in this
guide.

Requirements

In order to establish a PPP connection, the unit must have been
configured with a unit name and a valid IP address and subnet mask.
The ISDN network type must be configured correctly to match the
ISDN service.

To configure these parameters:

1

Enter QC NA to display the Unit Parameters screen.

2

Type the unique name for the unit in the Unit Name field. It can have
up to twelve characters. Do not include spaces in the unit name.

3

Type a valid IP address for the unit in the Unit LAN IP Address field.

4

Toggle the Network Type field to the correct ISDN network type using
the Spacebar, if required.

5

Press [Ctrl]+[E] to submit the new setting and then enter SAVE

C

A number of essential parameters have to be supplied by the Internet
Service Provider before configuration can be completed.

The parameters which have to be supplied by the ISP are:

■ The Internet Service Provider’s name.

■ The ISDN number to call at the ISP.

The Password Authentication Protocol (PAP) or Challenge

Handshake Authentication Protocol (CHAP) passwords required
to login to the ISP router. It is essential that the ISP specifies which
of these are used by their router.

Configuring a PPP Connection

A PPP connection can be most easily configured using the Quick
Configuration facility of the unit.

1

Enter QC IN to display the Connect To Another PPP IP Router screen.

2

Type the name supplied by the ISP in the Name of your Internet
Provider or remote site field. This field is for reference only.

3

Type the ISDN number for the ISP the ISDN number of the remote
unit you want to call field.

4

Toggle the Call Type field using the Spacebar to match the ISDN call
type specified by the ISP.

5

If the unit LAN port has already been configured, then the IP Address
of this unit’s LAN port field will contain that address.

■

If the LAN port has not been configured, please refer to Chapter

3 for details on how to configure the unit as an IP router.

6

If the unit LAN port has already been configured, then the IP Mask of
this unit’s LAN port field will contain the subnet mask.

■

If the LAN port has not been configured, please refer to Chapter

3 for details on how to configure the unit as an IP router.

ONNECTIONS

It is good practise to configure the PPP connection over ISDN to use

unnumbered

links because this makes best use of available IP

addresses and is simple to configure.

7

To configure the PPP connection to the ISP to use unnumbered links,
leave the following three fields set to

■

IP Address of this end of the ISDN link.

■

IP Address of the remote end of the ISDN link.

■

IP Mask of the ISDN link.

ID exactly as given because this field is case-sensitive.

The authentication protocol specified by the ISP determines which
one of password fields needs to be set. Occasionally, both a PAP and
a CHAP password are supplied. In this case, both fields must be
completed correctly.

12

If the ISP has supplied a PAP password, type the password in the PAP
Password to log into remote site field. Note that the password must
be entered exactly as given because this field is case-sensitive.

13

If the ISP has supplied a CHAP password, type the password in the CHAP
Password to log into remote site field. Note that the password must be
entered exactly as given because this field is case-sensitive.

Internet Service Providers may use either, or both, forms of user
authentication. No successful connection to the ISP will be possible
unless these parameters are configured correctly.

Press [Ctrl]+[E] to submit the new settings and then enter SAVE

If the ISP has already established an account then the PPP connection
can be tested by using “Ping” to send test IP packets to an Internet
site.
