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 connectio n is requested, the system
checks the username presented for validity, then dials
back the number associated with the username.

entries for your installation:

Router (config-if) # isdn spid2 SPID_no phone_number
