T1 Bert - HP 6600 Command Reference Manual

Default command level
2: System level
Parameters
line-number: T1 line number, in the range of 1 to 28.
detect: Enables/disables periodical alarm signal detection.
generate: Sends alarm signals, AIS or RAI, for line state test. ais: Alarm indication signal.
rai: Remote alarm indication signal.
Usage guidelines
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.
