This procedure is used to clear the

safe levels if an incoming loss of signal is detected. The
condition is generated when the Raman co- and/or counter-pump
line
powers have been reduced to safe levels as a result of SUPV and/or
DWDM loss of signal detection in OA and RP circuit packs. This
condition will be present as long as OTS LOS and/or OSC LOS
(opposite direction to optical channels) are present. The loss of
DWDM and SUPV signals is caused by a fiber cut in the outside
plant.
It is necessary to look at the upstream nodes to determine whether the
reported APR condition is caused by a problem in the local node or if
it has propagated to to this node from a problem further upstream.
Once you have identified the node furthest upstream that is reporting
an

source of the problem located between the second and third
downstream nodes. See
cut" (3-5).
When the incoming loss of signal is repaired, LambdaXtreme
Transport will resume normal operation and the APR active condition
will clear.
