Configuring An E1 Channel - H3C SR6602-X Configuration Manual

Step
8. Configure the SOH and
higher-order path overhead
bytes.
9. Set the physical state
change suppression interval
on the interface.
10. Set the signal degrade (SD)
or signal fail (SF) alarm
threshold for the interface.
11. (Optional.) Configure the
action to take when an RDI,
SD, or SF alarm occurs on
the CPOS interface.
12. (Optional.) Restore the
default settings for the CPOS
interface.
13. Bring up the CPOS interface.

Configuring an E1 channel

The serial interfaces created for E1 channels have the same logical features as a synchronous serial
interface. You can configure these serial interfaces in the same way you configure a standard
synchronous serial interface. For more information about configuring synchronous serial interfaces,
see "Configuring WAN
To configure an E1 channel:
Step
1. Enter system view.
2. Enter CPOS interface view.
3. Set the framing format for the
E1 channel.
4. Set the clock mode for the E1
channel.
5. (Optional.) Enable loopback
on the E1 channel.

Remarks
By default:
•
c2 is 0x02.
•
s1s0 is 0x00 for SONET and
0x02 for SDH.
•
j0 is 0x01 for SONET and a
16-byte empty character
string for SDH.
•
j1 is a 64-byte empty
character string for SONET
and a 16-byte empty
character string for SDH.
By default, the physical state
change suppression interval is 0
seconds.
By default, the SD threshold is
10e to the power of negative 6
–6
(10e ) and the SF threshold is
10e to the power of negative 3
–3
(10e ).
By default, the device does not
take any actions on the interface
when an RDI, SD, or SF alarm
occurs.
N/A
By default, a CPOS interface is
up.
If no cable is connected to a
physical interface, shut down the
interface with the shutdown
command to prevent problems.
Remarks

N/A
The default setting is no-CRC4.
The default setting is slave.
By default, loopback is disabled.
