e1 channel-set
Use e1 channel-set to bundle timeslots on an E1 line.
Use undo e1 channel-set to remove a timeslot bundle.
Syntax
e1 line-number channel-set set-number timeslot-list list
undo e1 line-number channel-set set-number
Default
No timeslots are bundled into channel sets.
Views
CE3 interface view
Default command level
2: System level
Parameters
line-number: E1 line number in the range of 1 to 16.
set-number: Number of the channel set formed by a timeslot bundle on the E1 line. It is in the range of
0 to 30.
timeslot-list list: Specifies the timeslots to be bundled. The list argument can contain multiple timeslot
numbers, each of in the range of 1 to 31. You can specify a single timeslot by specifying a timeslot
number, a range of timeslots by providing this argument in the form of { number1-number2 }, or multiple
timeslots by providing this argument in the form of { number1, number2-number3 }.
Usage guidelines
A CE3 interface can be channelized into 64 kbps lines and the timeslots on each E1 line can be bundled
into up to 31 channels.
When an E1 line operates in framed (CE1) mode, you can bundle timeslots on it into channel sets. For
each channel set, the system automatically creates a serial interface numbered serial
number/line-number:set-number. For example, the serial interface formed by channel set 0 on the first E1
line on E3 1/0 is numbered 1/0/1:0. This interface can operate at N × 64 kbps, and is logically
equivalent to a synchronous serial interface on which you can make other configurations.
Examples
# Create a 128 kbps serial interface on the first E1 channel on interface E3 2/0.
