Channel-Group Command for DS0 Time Slots and T1s
Figure 4-1
You create a logical channel group using the following command:
[no] t1 t1-number channel-group channel-group-number timeslots list-of-timeslots [speed
{56 | 64}]
Where:
• t1-number is T1 interface number 1 to 28.
• channel-group channel-group-number identifies the channel group with any number from 0 to 23.
• timeslots list-of-timeslots can be 1 to 24 or a combination of subranges within 1 to 24. You can
indicate a range using a hyphen, commas, or a combination of both. One time slot equals one DS0.
Refer to the examples below.
speed {56 | 64} is an optional argument that specifies the speed of a time slot as either 56 or 64 kbps.
•
The default is 64. (The 56-kbps time slots are generally used with older T1 equipment that does not
support B8ZS and are associated with SF framing.)
Use the no form of the command to remove a logical channel group.
The following examples show how to use the t1 channel-group command:
In this example, T1 interface 3 includes channel group 20 and consists of nine channelized time

slots:
Router(config)# controller t3 1/0/0
Router(config-controller)# t1 3 channel-group 20 timeslots 1-8, 10
To enter interface configuration mode for this channel group, enter the following:
Router(config)# interface serial 1/0/0/3:20
In the following example, T1 interface 4 includes channel group 18 and consists of all 24 time slots,

creating a full T1 interface:
Router(config)# controller t3 1/0/0
Router(config-controller)# t1 4 channel-group 18 timeslots 1-24
To enter interface configuration mode for this channel group, you enter the following:
Router(config)# interface serial 1/0/0/4:18
In the following example, T1 interface number 5 is divided into three channel groups, which total

11 time slots:
Router(config)# controller t3 1/0/0
Router(config-controller)# t1 5 channel-group 19 timeslots 1-6
Router(config-controller)# t1 5 channel-group 20 timeslots 10
Router(config-controller)# t1 5 channel-group 21 timeslots 7-9, 24
In the following example, channel group 20 is removed:
•
Router(config)# controller T3 1/0/0
Router(config-controller)# no t1 1 channel-group 20
