Command Remarks
9. Enable RAI detection on the
interface.
alarm detect rai
Optional.
Enabled by default.
This command is applicable when
the framing format is ESF.
10. Enable user data inversion.
data-coding { normal | inverted }
Optional.
Disabled by default.
11. Set the line idle code type.
idlecode { 7e | ff }
Optional.
The default is 0x7E.
12. Set the type of interframe
filling tag.
itf type { 7e | ff }
Optional.
The default is 0x7E.
13. Set the number of interframe
filling tags.
itf number number
Optional.
The default is 4.
14. Set alarm thresholds.
alarm-threshold { ais { level-1 |
level-2 } | lfa { level-1 | level-2 |
level-3 | level-4 } | los
{ pulse-detection | pulse-recovery }
value }
Optional.
By default:
• For LOS
3
alarm, the threshold of
pulse-detection is 176 and the
threshold of pulse-recovery is
22. If the number of the pulses
detected during the total length
of 176 pulse detection intervals
is smaller than 22, the
pulse-recovery threshold, a
LOS alarm occurs.
• Both AIS
4
alarm threshold and
LFA
5
alarm threshold are level-1.
15. Set the behavior of the
interface on the FDL in ESF
framing.
fdl { ansi | att | both | none }
Optional.
The default is none, meaning that
FDL is forbidden.
16. Enable loopback.
loopback { local | payload |
remote }
Optional.
Disabled by default.
17. Send remote loopback control
code.
sendloopcode { fdl-ansi-llb-down |
fdl-ansi-llb-up | fdl-ansi-plb-down
| fdl-ansi-plb-up |
fdl-att-plb-down | fdl-att-plb-up |
inband-llb-down | inband-llb-up }
Optional.
No remote loopback control code
is sent by default.
18. Set the intended bandwidth
for the CT1 interface.
bandwidth bandwidth-value Optional.
19. Shut down the CT1/PRI
interface.
shutdown
Optional.
A CT1 interface is up by default.
20. Return to system view
quit N/A
21. Enter the view of the
synchronous serial interface
created on the CT1 interface.
