APRTOPO
APRTOPO (APR Active - Invalid Topology)
When an LD is used that contains a high-power optical amplifier (>20 dBm), certain ports
within the add/drop node or ILA must be monitored for possible fiber breaks. These
monitored ports check for LOS, and upon detecting LOS, cause an APRNODE condition.
Software checks that a valid topology is in place (including all necessary monitoring
ports) before allowing the LD to turn on. When a topology has been provisioned and
validated by software, the alarm will clear and the optical amplifier in the LD will be
allowed to turn on. When a topology is first being entered, the alarm will be present until
all topological connections that must be monitored have been entered. If the optical
amplifier is on, but a monitored topological connection is deleted, the optical amplifier
will shut down. It will remain off until after a new topology is created and validated by
software.
