+Defines interesting packets to trigger dial out

XSR(config-if<D1>)#dialer idle-timeout 20

+Terminates call to Toronto if the line is idle for 20 seconds

XSR(config-if<D1>)#no shutdown

The following commands add a dial pool member and set the Central Office switch type on BRI interface 1/0:

XSR(config)#interface bri 1/0

XSR(config-if<BRI-1/0>)#isdn switch-type basic-net3

XSR(config-if<BRI-1/0>)#dialer pool-member 1

XSR(config-if<BRI-1/0>)#no shutdown

The following command maps ACL 101 to dialer group 1:

XSR(config)#dialer-list 1 protocol ip list 101

The following command defines interesting packets for the dial out trigger by configuring access list 101 to pass all Type 8 source and destination ICMP traffic up to 20 idle seconds:

XSR(config)#access-list 101 permit icmp any any 8
