PWRADJREQ
PWRADJREQ (Power Adjust Required)
A PWRADJREQ condition is raised when:
• Adding a channel on a non-commissioned network:
For example, a ring network can be commissioned with ASE power adjusts which
require no services to be added to power balance the network. When a service is
added after this type of commissioning is done, the PWRADJREQ alarm will not be
raised.
• Adding a service after an ingress or egress adjust failed because no service was
present or configured at the time:
Once the service has been provisioned, this alarm is raised and an adjustment of the
power is required.
• Reinserting a pack when services are present across the affected topology
• Changing the network EPT parameter values and breaking the line fiber into the
ingress LD
• Clearing a LOS condition on the LD
An ingress adjustment requires an ingress service (drop or through) to complete. An
egress adjustment requires a through service to complete; in the case of a terminal line
only an add path service is required. For a TOADM line both add path and through path
services are required to completely optimize the line; if services are provisioned across
only the add path or through path the PWRADJREQ condition is cleared only for that
path.
Masking of PWRADJREQ: If an event occurs on a network element that would cause
PWRADJREQ to be raised, but there are no channels provisioned at the affected optical
line, the PWRADJREQ condition is masked. The condition will only be raised when a
channel is provisioned that would allow the required SCOT power adjustment to be run to
clear the PWRADJREQ. This means that provisioning of a channel may result in
unmasking of one or more PWRADJREQ conditions.
