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 Configuration Requirements
You need to consider the following when you configure PPP or Frame Relay with
ISDN:
v The ISDN interface will not enforce transmit delay counters that you set in the
PPP configurations.
v Do not enable psuedo-serial-ethernet on the dial circuit.
Before You Begin
Before you configure ISDN, you need the following information:
v Telephone number of the local ISDN port.
v Destination telephone numbers, including any telephone extensions.
v Type of switch to which the ISDN interface is connected. See “Switches/Services
Supported” 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.
Configuration Procedures
This section describes how to configure your ISDN interface and its associated dial
circuits. Specifically, the tasks you need to perform are:
1. Adding ISDN addresses
2. Configuring ISDN parameters
3. Configuring the ISDN Interface (PRI only)
4. Adding dial circuits
5. Configuring dial circuits
Note: You must restart the router for configuration 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:
v
Address Name
. The address name is a description of the address. You can use
any string of up to 23 printable ASCII characters.
v
Network 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.
