R3102-R3103-HP 6600/HSR6600 Routers Interface Command Reference

162
Default command level
2: System level
Parameters
detect: Enables/disables periodical alarm signal detection.
generate: Sends alarm signals, which can be AIS, RAI, idle, or FEBE for line state test. ais: Alarm
indication signal.
febe: Far end block error signal.
idle: Idle signal.
rai: Remote alarm indication signal.
Usage guidelines
At the startup of your device, periodical alarm signal detection is enabled on the CT3 interface. When
detecting LOS, LOF, or AIS signals, the interface sends RAI signals to its peer. Alarm state report for the
interface is real time; you may view that by performing the display controller t3 command.
The supported alarm signals, LOS, LOF, AIS, RAI, FEBE, and idle, are ANSI T1.107-1995 compliant.
You can only configure the CT3 interface to send a type of alarm signal. To have the interface send
another type of signal, use the undo alarm command to remove the previous setting first. In addition,
when the RAI signal generated upon detection of the LOS, LOF, or AIS signal is present, the CT3 interface
cannot send another type of signal. To do that, use the undo alarm detect command to disable the CT3
interface from sending the RAI signal generated upon detecting an alarm first.
You may view the alarm state information by using the display controller t3 command.
Examples
# Enable periodical alarm signal detection on CT3 interface T3 2/0/0.
<Sysname> system-view
[Sysname] controller t3 2/0/0
[Sysname-T3 2/0/0] alarm detect
# Enable CT3 interface T3 2/0/0 to send AIS alarm signals.
<Sysname> system-view
[Sysname] controller t3 2/0/0
[Sysname-T3 2/0/0] alarm generate ais
bert (CT3 interface)
Use bert to start a BERT test on the CT3 interface.
Use undo bert to stop the BERT test running on the CT3 interface.
