Configuring

ISDN

If you have an ISDN BRI WAN module, configure the BRI port for ISDN. This section explains typical ISDN configurations for one or two B channels. In the examples, the BRI port is configured for IP routing and Point-to-Point Protocol (PPP) encapsulation.

Complete these steps to configure the router for a basic ISDN PPP connection on a single B channel or two B channels, substituting th correct address and host names as appropriate for your network.

1. Enter enable mode:

Router> enable

Password: enable password

2. Enter the configure terminal command.

Router# config term

3.If you have not already done so, enter the isdn switch-typecommand to configure the ISDN switch type:

router (config) # ISDN switth-type switch-type

4.Enter the BRI interface, encapsulation method (PPP), authentica tion type, target router’s IP address and ISDN number to dial, and the dialer group number:

Router (config) # interface bri 0 Router (config-if) # encapsulation ppp Router (config-if) #ppp authentication chap

Router (config-if) # dial map ip targetrouter_ipaddress targetrouter_phonenumber Router (config-if) # dialer-group groupnumber

Do not use periods or hyphens when you are entering dialing num-

bers.
Note:	The ISDN/BRI interface provides dial backup for the
	AI2524 card. When a connection is requested, the system
	checks the username presented for validity, then dials
	back the number associated with the username.
