Controller configuration:
Default
cas
Example
This configuration instructs the XSR to terminate timeslots 1, 2, 3, 4, 5, 6 and 7 of controller T1 0/1/
0 into a PPP channel and bypass the rest of the timeslots from T1 controller 0/1/0 to controller T1 0/
1/1. controller port T0/1/0 is connected to the Central Office and controller port T0/1/1 is connected
the the PBX down stream. Note that setting the clock source to internal is mandatory.

show controller
For Drop & Insert NIM only
This command, useful for debugging, lists the bypassed time slots between the two T1 controllers
on the NIM and associated CASABCD signaling bits received. The Rx ABCD row displays the hex
value of the CAS signaling bits received by the controller. Timeslots terminated in the XSR are
marked with an asterisk (*). Those timeslots are used for data on ports 1 and/or 0. The bypass
timeslot table will display only if the configuration is correct, that is, D&I is enabled on both ports
and one of the ports employs internal clocking.This command may help debugging CAS voice
calls.
Syntax
show controller t1 {slot | card | 0/1}
Example
This example shows port 0 using timeslot 10 for data and port 1 using timeslots 1 ‐ 6 for data:
T1 0/1/0 is Admin Up and Oper Up.
T1 with CSU Interface.
