The Maintenance > ALS subtab allows you to provision the automatic laser shutdown (ALS) on the
OPT-BST, OPT-BST-L, OPT-PRE, OPT-AMP-L, and OPT-AMP-C cards. ALS parameters control the circumstances when the OPT-BST, OPT-BST-L, OPT-PRE, OPT-AMP-L, OPT-AMP-C, and OPT-AMP-17-C lasers are turned off and turned back on.

|
Allows you to turn the OPT-BST or OPT-PRE laser on or off. When optical safety remote interlock (OSRI) is set to On, the laser is turned off. If OSRI is set to OFF, the laser can be turned on according to the 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. |
