Configuring a T1 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 T1.
t1 t1-number set frame-format { esf
| sf }
Optional.
ESF by default.
4. Set the clock mode for T1.
t1 t1-number set clock { master |
slave }
Optional.
Slave by default.
5. Set the loopback mode for T1.
t1 t1-number set loopback { local |
payload | remote }
Optional.
Disabled by default.
6. Set the overhead bytes for T1.
t1 t1-number set flag c2 c2-value
t1 t1-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 T1 operating
mode.
• Method 1:
Configure T1 to operate in
unframed mode:
t1 t1-number unframed
• Method 2:
Configure T1 to operate in
framed mode, and set timeslot
bundling:
a. (Optional) undo t1
t1-number unframed
b. t1 t1-number channel-set
set-number timeslot-list
range [ speed { 56k |
64k } ]
Use either method.
By default:
• T1 operates in framed mode.
• A T1 channel is not
channelized.
8. Shut down the specified T1
channel.
t1 t1-number shutdown
Optional.
By default, a T1 channel is up.
9. Configure the bundling mode
of the serial interface formed
by bundling the timeslots of
the T1 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:
T1 configuration is supported on the CPOS (T) interface module.
