Step Command Remarks
6. Set the line code format.
ft1 code { ami | b8zs } The default is B8ZS.
7. Set the clock mode.
ft1 clock { master | slave }
The default is slave, which is line
clock.
8. Set the framing format.
ft1 frame-format { esf | sf } The default is esf.
9. (Optional.) Enable RAI
detection on the interface.
ft1 alarm detect rai
By default, RAI detection is
enabled on the interface.
This command is applicable when
the framing format is ESF.
10. (Optional.) Enable user data
inversion.
ft1 data-coding { inverted |
normal }
By default, user data inversion is
disabled.
11. Set the type of line idle code.
ft1 idlecode { 7e | ff } The default is 0x7E.
12. Set the type of interframe
filling tag.
ft1 itf type { 7e | ff } The default is 0x7E.
13. Set the number of interframe
filling tags.
ft1 itf number number The default is 4.
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.
