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-list range: 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.

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

Use the undo e1 channel-set command 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.

T1 framer(2-1-1): 

Presents how the T1 channel is multiplexed. 2-1-1 
represents in order VC-3 number, TUG-2 number, and 
TUG-11 number for the T1 channel.

For its calculation principle, refer to the accompanied 
operation manual.
