ISDN Configuration
XSR User’s Guide 11-13
Figure 11-2 .PRI Configuration Model
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-group command 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.
XSR(config)#interface dialer 1
XSR(config-if<D0>)#ip address 1.1.1.1 255.255.255.0
XSR(config-if<D0>)#encapsulation ppp
XSR(config-if<D0>)#dialer string 17574231234 class rem node1
XSR(config-if<D0>)#dialer pool 1
XSR(config-if<D0>)#dialer-group 1
XSR(config-if<D0>)#no shutdown
XSR(config)#controller t1 1/0/0
XSR(config-controller<T1-1/0/0>)#pri-group
XSR(config-controller<T1-1/0/0>)#isdn switch-type primary-ni
XSR(config-controller<T1-1/0/0>)#isdn bchan-number-order ascending
XSR(config-controller<T1-1/0/0>)#dialer pool-member 1 priority 100
XSR(config-controller<T1-1/0/0>)#dialer pool-member 2 priority 50
XSR(config-controller<T1-1/0/0>)#no shutdown
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
