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 can 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,
