Dial Line

The following T1 example configures the interface for ISDN PRI operation, adds a dialer pool and group, and one dialer string to the node’s Dialer 1 port. The ISDN PRI interface belongs to two prioritized pool members. You can add map class, dialer list and ACL commands not shown.

The pri-groupcommand enables ISDN and configures all timeslots to map to channel groups on the PRI NIM card: for a T1 NIM, 23 B and one D channel, for an E1 NIM, 30 B and one D channel.

Optionally, the following E1 commands set the Central Office switch type and add prioritized pool members to E1 1/0/0:15 D-channel sub-interface:

XSR(config)#controller e1 1/0 XSR(config-controller<E1-1/0>)#isdn switch-type primary-net5 XSR(config-controller<E1-1/0>)#isdn bchan-number-order ascending XSR(config-controller<E1-1/0>)#no shutdown XSR(config-controller<S1-1/0>)#dialer pool-member 1 priority 100 XSR(config-controller<S1-1/0>)#dialer pool-member 2 priority 50
