Parameter
line-number: T1 line number in the range of 1 to 28.
set-number: The number of the channel-set formed by bundling the timeslots of
T1 line, which is in the range of 0 to 23.
range: The number of the timeslots that are bundled, which is in the range of 1 to
24. When specifying the timeslots to be bundled, you can specify a single timeslot
by specifying a number, a range of timeslots by specifying a range between
number1-number2, or several discrete timeslots by specifying number1,
number2-number3.
speed: Timeslot bundling mode. If 56k is selected, the timeslots will be bundled
into N x 56Kbps. If 64k is selected, the timeslots will be bundled into N x 64 Kbps.
Speed defaults to 64k.
Description
Using the t1 channel-set command, you can bundle the timeslots of a T1 line.
Using the undo t1 channel-set command, you can remove the timeslot bundle.
By default, no timeslots are bundled into channel-sets.
When a T1 line operates at framed (CT1) mode, you can bundle the timeslots on
it. The system will automatically create a serial interface numbered serial number /
line-number:set-number for the channel-set. This interface operates at N x 64
Kbps (or N x 56 Kbps) and has the same logic features of a synchronous serial
interface on which you can make other configurations.
For a related command, see t1 unframed.
Example
Bundle a 128Kbps serial interface on the first T1 line on the interface T3 1/0/0.
