To add a V.25bis address, enter the add v25-bis-addresscommand at the Config> prompt. For example:

Assign address name [1-23] chars []? remote-site-baltimore

Assign network dial address [1-30 digits][]? 19095551234

Con®guring the V.25bis Interface

This section explains how to con®gure the V.25bis interface. To con®gure, do the following:

1.To set up a serial line interface for V.25bis, set the data-link protocol for the serial line interface. From the Config> prompt, use the set data-link v25bis command. For example:

Config>set data-link v25bis

Interface Number [0]? 2

2.Display the V.25bis Config> prompt by entering the network command followed by the number of the interface. For example:

Config>network 2

V.25bis Data Link Configuration

V25bis Config>

You can use the list devices command at the Config> prompt to display a list of interface numbers con®gured on the router.

3.Use the set local-addresscommand to specify the network address name of the local port. You must enter one of the address names you de®ned using the add v25bis-addresscommand. For example:

V25bis Config>set local-address

Local network address name []? remote-site-baltimore

 

Note: You must restart the router for con®guration changes to take effect.

 

Optional V.25bis Parameters

 

The following are optional V.25bis parameters you can set. For a complete

 

description of these commands, see ªV.25bis Con®guration Commandsº on

 

page 583 .

 

v You can limit the number of successive calls to an address that is inaccessible or

that refuses those calls. To do so, use the set retries-no-answerand the set

 

timeout-no-answer commands.

 

v The set disconnect-timeoutcommand controls the amount of time the router

 

waits to initiate a call after dropping a signal from the previous call.

 

v The set command-delay-timeoutcommand speci®es the amount of time the

 

router waits to initiate or answer a call after it turns on DTR.
