HP MSR Router Series Configuration Guide

Step Command Remarks
14. Set alarm thresholds.
ft1 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 alarm threshold are level-1.
15. Set the behavior of the
interface on the FDL in ESF
framing.
ft1 fdl { ansi | att | both | none }
By default, FDL is disabled.
16. (Optional.) Enable loopback
and set the loopback mode.
ft1 loopback { local | payload |
remote }
By default, loopback is disabled.
17. (Optional.) Send remote
control loopback code.
ft1 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 control code
is sent.
18. Set the CRC mode.
crc { 16 | 32 | none } By default, 16-bit CRC is adopted.
19. Set the MTU for the BRI
interface.
mtu size The default is 1500 bytes.
20. Set the keepalive transmission
interval.
timer-hold seconds The default is 10 seconds.
21. (Optional.) Set the intended
bandwidth for the T1-F
interface.
bandwidth bandwidth-value
By default, the expected
bandwidth (in kbps) is the interface
baud rate divided by 1000.
22. (Optional.) Restore the default
settings for the T1-F interface.
default N/A
23. Bring up the T1-F interface.
undo shutdown By default, a T1-F interface is up.
Starting a BERT test on a T1-F interface
BERT operates as follows:
1. The local end sends out a pattern, which is looped over on the line and sent back to the local end.
2. The local end checks the received pattern for the bit error rate to help determine the line condition.
You must configure loopback to allow the transmitted pattern to loop back from a specific point on the
line. For example, enable far-end loopback on the remote interface.
To start/terminate a BERT test on a T1-F interface:
