View CT3 interface view

Parameter line-number: T1 line number, in the range 1 to 28.

detect: Enables/disables periodical alarm signal detection. By default, periodical alarm detection is enabled.

generate: Sends alarm signals, AIS or RAI, for line state test. By default, alarm signal sending is disabled.

ais: Alarm indication signal.

rai: Remote alarm indication signal.

Description Use the t1 alarm command to enable the specified T1 line on the CT3 interface to detect/send alarm signals.

Use the undo t1 alarm command to remove the alarm signal detection/sending setting.

At the startup of the router, periodical alarm signal detection is enabled on all T1 lines on the CT3 interface. When a T1 line detects LOS, LOF, or AIS signals, it sends RAI signals to its peer. Alarm state report for the interface is real time; you may view that with the display controller t3 command.

The supported alarm signals, LOS, LOF, AIS, RAI, FEBE, and idle, are ANSI T1.403 compliant.

You can configure a T1 line to send only a type of alarm signal. To have the channel send another type of signal, use the undo t1 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 T1 line cannot send another type of signal. To do that, use the undo t1 alarm detect command to disable the T1 line to send the RAI signal generated after detecting an alarm first.
