Parameter e1-number: Number of an E1 channel on the CPOS interface, in the range 1 to 63.

set-number: Channel set number, in the range 0 to 30.

timeslot-listrange: Specifies a list of timeslots assigned to the channel set. The range argument is in the range 1 to 31. While specifying timeslots, you can specify a single timeslot in the form of a number, or timeslots in a range in the form of number1-number2, or multiple timeslots in the form of number1, number2-number3.

Description Use the e1 channel-setcommand to bundle multiple timeslots on an E1 channel into one channel set.

Use the undo e1 channel-setcommand to remove the channel set (also mentioned as a bundle throughout this document).

By default, timeslot bundling is disabled on E1 channels.

When the E1 channel is channelized, its timeslot 0 is used for synchronization and the other 31 timeslots can be bundled to form one or multiple serial interfaces. These serial interfaces are numbered in the form of interface number/channel number:channel set number.

To guarantee the processing capacity of the system, you can have only up to 256 virtual serial interfaces on one CPOS physical interface.
