Channel-Group Command for DS0 Timeslots and T1s
Each channelized T3 consists of 28 T1s, each of which is divided into 24 timeslots (or DS0s). To create
an interface that supports subscriber traffic, you must combine the timeslots into channel groups. Use
the t1 channel-group command to create a channel group.
Channel groups have these characteristics:

A channel group is an interface.
A channel group can be one timeslot to 24 timeslots in size.
A channel group that consists of 24 timeslots is a T1 interface.
–
A channel group that consists of fewer than 24 timeslots can be described as a fractional T1
–
interface.
Each group of 24 timeslots can be divided into multiple fractional T1 interfaces.
A channel group cannot be part of more than one T1.
