The dialer map command is used with CHAP authentication to place the initial call to the remote router when interesting traffic is forwarded to the BRI interface. After the connection is active, the dialer idle-timeout command determines how long it will remain active. A dialer map statement is required for each ISDN phone number that will be called. Be aware though, that two dialer map statements pointing to the same location might activate both B channels when you may only want to use one channel.
Note: The command parameters for this example are:
172.16.20.1 = the IP address of the remote router's BRI interface. To determine this address, type show interface bri 0 at the remote router's console prompt.
name C2503 = the hostname of the remote router. The name is case sensitive and should match the name configured for the username command above.
speed 56 = sets the dialer speed to 56k for ISDN circuits that are not 64k end-to-end, and should be included in both routers' dialer map statements. Most installations in North America must be configured for 56K.
broadcast = allows the forwarding of broadcast packets. Unless broadcast packets are specified as interesting packets by the dialer-list command, they will only be forwarded when the ISDN link is active.
14085554321
14085559876 = the remote router's ISDN telephone numbers.
