HP MSR2000/3000/4000 Router Series Interface Configuration Guide

Step Command Remarks
6. Set the clock mode.
clock { master | slave }
The default is slave, which is line
clock.
7. Set the framing format.
frame-format { sf | esf } The default is ESF.
8. Enable RAI detection on the
interface.
alarm detect rai
By default, RAI detection is
enabled on the interface.
This command is applicable when
the framing format is ESF.
9. Enable user data inversion.
data-coding { normal | inverted }
By default, user data inversion is
disabled.
10. Set the line idle code type.
idlecode { 7e | ff } The default is 0x7E.
11. Set the type of interframe
filling tag.
itf type { 7e | ff } The default is 0x7E.
12. Set the number of interframe
filling tags.
itf number number The default is 4.
13. 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 }
By default:
• For LOS 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 alarm threshold and
LFA
5
alarm threshold are level-1.
14. Set the behavior of the
interface on the FDL in ESF
framing.
fdl { ansi | att | both | none }
The default is none, meaning that
FDL is forbidden.
15. Enable loopback.
loopback { local | payload |
remote }
By default, loopback is disabled.
16. 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 }
By default, no remote loopback
control code is sent.
17. Restore the default settings for
the CT1/PRI interface.
default
N/A
18. (Optional.) Bring up the
CT1/PRI interface.
undo shutdown
By default, a CT1/PRI interface is
up.
19. Enter the view of the
synchronous serial interface
created on the CT1/PRI
interface.
interface serial
interface-number:set-number
or
interface serial
interface-number:23
N/A
20. Set the CRC mode.
crc { 16 | 32 | none } By default, 16-bit CRC is adopted.
