ALS Mode
Allows you to provision the automatic laser shutdown:
Disable—ALS is off; the laser is not automatically shut down when traffic outages (loss of signal [LOS]) occur.
Auto Restart—ALS is on; the laser automatically shuts down when traffic outages (LOS) occur. It automatically restarts when the conditions that caused the outage are resolved.
Manual Restart—ALS is on; the laser automatically shuts down when traffic outages (LOS) occur. However, the laser must be manually restarted when conditions that caused the outage are resolved.
Manual Restart for Test—Manually restarts the laser for testing.

Recovery Pulse Interval (sec)

Currently Shutdown
Indicates whether the laser is currently shut down, either On or Off.
Request Laser Restart
