ISDN Interface Restrictions

v You cannot boot or dump the router over an ISDN interface.

v Except for BRI, which allows you to use the D-channel for X.25 packet data, you

cannot use the D-channel for data traffic. Normally the D-channel is used only for

setting up and taking down B-channel connections.

Dial Circuit Con®guration Requirements

You need to consider the following when you con®gure PPP or Frame Relay with

ISDN:

vThe ISDN interface will not enforce transmit delay counters that you set in the PPP con®gurations.

vDo not enable psuedo-serial-ethernet on the dial circuit.

Before You Begin

Before you con®gure ISDN, you need the following information:

vTelephone number of the local ISDN port.

vDestination telephone numbers, including any telephone extensions.

vType of switch to which the ISDN interface is connected. See ªSwitches/Services Supportedº on page 618 for the list of switches.

Note: Additional parameters, such as TEI and SPID may be required based on your Switch Type and your service provider.

Con®guration Procedures

This section describes how to con®gure your ISDN interface and its associated dial circuits. Speci®cally, the tasks you need to perform are:

1.Adding ISDN addresses

2.Con®guring ISDN parameters

3.Con®guring the ISDN Interface (PRI only)

4.Adding dial circuits

5.Con®guring dial circuits

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

Adding ISDN Addresses

You need to add an ISDN address for each ISDN interface as well as for each destination. The ISDN address includes:

vAddress Name. The address name is a description of the address. You can use any string of up to 23 printable ASCII characters.

vNetwork Dial Address. Telephone number of the local or destination port. You can enter up to 25 numbers as well as 6 characters, including punctuation. The router uses only the numbers.
