Configuring an E1 channel
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter CPOS interface view.
controller cpos cpos-number N/A
3. Set the framing format for E1.
e1 e1-number set frame-format
{ crc4 | no-crc4 }
Optional.
no-CRC4 by default.
4. Set the clock mode for E1.
e1 e1-number set clock { master |
slave }
Optional.
Slave by default.
5. Set the loopback mode for E1.
e1 e1-number set loopback { local
| payload | remote }
Optional.
Disabled by default.
6. Set the overhead bytes for E1.
e1 e1-number set flag c2 c2-value
e1 e1-number set flag j2 { sdh |
sonet } j2-string
Optional.
By default, C2 is set to
hexadecimal 02 and J2 is cyclic
null.
7. Configure the E1 operating
mode.
• Method 1:
Configure E1 to operate in
unframed mode:
e1 e1-number unframed
• Method 2:
Configure E1 to operate in
framed mode and set timeslot
bundling:
a. (Optional) undo e1
e1-number unframed
b. e1 e1-number channel-set
set-number timeslot-list
range
Use either method.
The default setting is:
• E1 operates in framed mode.
• An E1 channel is not
channelized.
8. Shut down the specified E1
channel.
e1 e1-number shutdown
Optional.
Up by default.
9. Configure the bundling mode
of the serial interface formed
by bundling the timeslots of
the E1 channel.
ppp mp soft-binding
undo ppp mp soft-binding
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.
NOTE:
E1 configuration is supported on the CPOS (E) interface module.
