ALS


The ALS subtab allows you to provision the automatic laser shutdown (ALS).

Port

The port number.

ALS Mode

Allows you to provision the automatic laser shutdown:

  • Disable: ALS is off; the laser is not automatically shut down when traffic outages (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 Duration (sec)

Sets the recovery laser pulse duration, in seconds, for the initial, recovery optical power pulse following a laser shut down.

Recovery Pulse Interval (sec)

Sets the recovery laser pulse interval, in seconds. This is the period of time that must past before the recover pulse is repeated.

Currently Shutdown

Indicates whether the laser is currently shut down, either On or Off.

Request Laser Restart

If ALS Mode is set to Manual Restart or Manual Restart for Test, the check box is available after a laser shut down so you can restart it.

Note: Restarting a laser might be traffic-affecting.
