purpose of channel-group in T1 controller configuration
Posted on 2008-10-02
I have 2 aging Cisco MC3810 concentrators. I am trying to reconfigure T1 connectivity on them and running into problem with channel-group statement.
I have a private T1 with both 3810 routers configured in the bridge mode. Here is the part of config file that shows configuration of T1 controller:
controller T1 0
clock source internal
channel-group 3 timeslots 7-24 speed 64
tdm-group 0 timeslots 1-6
When I change channel-group statement to: "channel-group 3 timeslots 1-24 speed 64" and remove
"tdm-group 0 timeslots 1-6" statement, I loose communication via T1.
I ultimately need to reconfigure the router so I have full T1 for IP traffic. I used to have digital PBX on it and that's why I think there is this separation of timeslots.
Thanks in advance,
