Note
For consistency throughout the following configuration examples and whenever possible, the port
addresses 1/0/0 and 1/0/0/1:1 are used for Cisco 7500 series routers and 1/0 and 1/0/1:1 for Cisco 7200
series routers.
Your PA-MC-2T3+ port addressing might be different depending on the Cisco 7200 series router chassis
slot or the interface processor slot in which your VIP is installed and the VIP port adapter slot in which
your PA-MC-2T3+ is installed.
Creating a Logical Channel Group on a T1 Line
You can create a logical channel group on a T1 line using the following controller command:
t1
t1-line-number
channel-group
channel-group-number
timeslots
list-of-timeslots
[
speed
{56 | 64}]
where:
•
t1-line-number
is 1–28.
•
channel-group
defines a logical channel group.
•
channel-group-number
is 0–23.
•
timeslots
list-of-timeslots
can be 1–24 or a combination of subranges within 1–24 (each subrange
is a list of timeslots of the T1 line).
•
speed
{56 | 64} is an optional argument that specifies the speed of a time slot to be either 56 kbps or
64 kbps.
Configure logical channel group 20 on T1 line 1 and assign channelized timeslots 1 to 5 and 20 to 23.
The example that follows is for a port adapter on a VIP in interface processor slot 1:
Router(config)#
controller T3 1/0/0
Router(config-controller)#
t1 1 channel-group 20 timeslots 1-5, 20-23
