alarm relay on the 3000 Series Carrier. The alarm deactivates if the condition(s) causing it
is corrected. An Alarm Cut-Off issued from the SDCP (or PC Emulation program) for a
particular carrier-mounted DSU/CSU also deactivates the alarm. The carrier-mounted
DSU/CSU does not reactivate the alarm relay until all alarm conditions for the unit are
cleared.
The following alarm conditions activate the alarm relay if this configuration option is
enabled:
Continuous Loss of Signal (LOS) or Out of Frame (OOF) at the network or DTE
Drop/Insert (DSX-1) interface.
Continuous Out of Frame (OOF) at any synchronous data port that has the Embedded
Data Link enabled.
Alarm Indication Signal (AIS) received at either the network or DTE Drop/Insert
(DSX-1) interface.

interface.
