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

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

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.

Configuring a Remote Unit from the Central Site

A unit at a remote site can be remotely configured as an IP bridge. 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.
CAUTION:

Configuration steps are given for:
Manual configuration of the central site router.
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.
