Step
6.
Set the overhead bytes for E1.
7.
Configure the E1 operating
mode.
8.
Shut down the specified E1
channel.
9.
Configure the bundling mode
of the serial interface formed
by bundling the timeslots of
the E1 channel.
NOTE:
E1 configuration is supported on the CPOS (E) interface module.

Remarks
Optional.
By default, C2 is set to
hexadecimal 02 and J2 is cyclic
null.
Use either method.
The default setting is:
•
E1 operates in framed mode.
•
An E1 channel is not
channelized.
Optional.
Up by default.
Optional.
By default, the hardware bundling
mode is adopted.
The HIM-CL1P and HIM-CL2P
interface modules do not support
cross-port hardware MP bundling.
On these interface modules, you
can use software bundling to meet
cross-port MP requirements.
