The automatic power reduction mode has been invoked on the optical line. The APRLINE
condition is reported against the egress amplifier when a LOS is detected on the ingress
amplifier, or as a result of OSC failure, when the span is equipped with an RA2P. The
APRLINE condition is raised against the output port of the egress amplifier. If the egress
is a unidirectional amplifier (AM2125A, AM2125B), the condition is raised against the
Line port. If the egress is a bidirectional amplifier, the condition is raised against the Sig
port.

Service affecting? Yes
Applicability ALPHG, AHPHG, AHPLG, ALPFGT, AM2017B, AM2125A,
AM2125B, AM2325B, RA2P
At the end of each step wait to see if the fault clears. If not, continue with the next step.

1
Determine the ingress amplifier that is connected to the egress amplifier reporting the
APR condition.

3
Check that the OSCs at both ends of the span are set to OC3.

4
Proceed to “LOS” (p. 2-148) to clear the LOS condition.

5
The APRLINE condition will automatically clear up to 100 seconds after the ingress LOS
condition has been cleared.
