Description
Using the channel-set command, you can bundle some timeslots of a CE1/PRI
interface into a channel-set. Using the undo channel-set command, you can
remove the specified timeslot bundle.
By default, no timeslots are bundled into channel-sets.
A CE1/PRI interface in CE1/PRI mode is physically divided into 32 timeslots
numbered from 0 through 31.
In actual applications, all the timeslots except timeslot 0 can be bundled into
multiple channel-sets and the system will automatically create a serial interface for
each set. This serial interface has the same logic features of synchronous serial
interface.
The serial interface is numbered in the form of serial interface-number
:set-number. The interface-number starts from the maximum serial interface
number plus 1, and the set-number is the number of the channel-set.
Only one timeslot bundling mode can be supported on one CE1/PRI interface
during a time period. In other words, this command cannot be used together with
the pri-set command.
For related command, see pri-set.
Example
Bundle the timeslots 1, 2, 5, 10-15, and 18 of the CE1/PRI interface into
channel-set 0.
[3com-E1 3/0/0]channel-set 0 timeslot-list 1,2,5,10-15,18
Make the same configuration on the CE1/PRI interface on the remote router.
[3com-E1 3/0/0]channel-set 0 timeslot-list 1,2,5,10-15,18
