Default command level
2: System level
Parameters
detect: Enables periodical detection on the interface.
rai: Remote Alarm Indication (RAI).
Usage guidelines
This command is applicable when the framing format used on the interface is ESF.
Examples
# Disable RAI detection on CT1 interface T1 2/0/0.
<Sysname> system-view
[Sysname] controller t1 2/0/0
[Sysname-T1 2/0/0] undo alarm detect rai
alarm-threshold
Use alarm-threshold to set LOS, AIS, or LFA alarm thresholds on the CT1 interface.
Use undo alarm-threshold to restore the default.
Syntax
alarm-threshold { ais { level-1 | level-2 } | lfa { level-1 | level-2 | level-3 | level-4 } | los { pulse-detection
| pulse-recovery } value }
undo alarm-threshold { ais | lfa | los { pulse-detection | pulse-recovery } }

Parameters
ais: Sets the alarm threshold of alarm indication signal (AIS), which can be level-1 and level-2.
• The level-1 keyword specifies generating an AIS alarm when the number of 0s in the bit stream of
an SF or ESF frame is less than or equal to 2.
• The level-2 keyword specifies generating an AIS alarm when the number of 0s is less than or equal
to 3 in the bit stream of an SF frame or less than or equal to 5 in the bit stream of an ESP frame.
Level-1 AIS alarm threshold applies.
lfa: Sets the loss of frame align (LFA) alarm threshold, which can be level-1, level-2, level-3, and level-4.
• The level-1 keyword specifies generating an LFA alarm when two of four frame alignment bits are
lost.
• The level-2 keyword specifies generating an LFA alarm when two of five frame alignment bits are
lost.
