Issue 1, June 2002
This is the signal power transmitted for the specified optical channel.
This parameter is measured by the OMON at the outside plant-facing
OA at every NE in the OLS. The SPT-C parameter has an associated
baseline value and user-provisionable performance thresholds.
Performance parameter thresholds are set to show degraded
performance by generating a defined notification from changes in
parameter values. The thresholds are set relative to the baseline value.
The baseline value can be established automatically or manually with
an externally initiated user command. The baseline value is displayed
in the PM report, next to the currently measured value, in dBm.
Re-baselining
If thre are fewer than eight channels present on a line, then all the
channels on a line are automatically re-baselined when a new channel
is added. If a ninth channel is added, then only the new channel is
re-baselined.
Upon deletion of an optical channel, if there are fewer than eight
channels remaining, then all the optical channels are automatically
baselined. Re-baselining can be initiated manually by an external user
command.
CAUTION
When an attempt to update the baseline SPT-C value is
made, any optical channel that is in a defect (LOS) state will
not be baselined.
This is the amount of per-channel optical power that is being received,
as measured by the OMON at the RP circuit pack in every NE of the
OLS. The SPR-C parameter has an associated baseline value and
user-provisionable performance thresholds. Performance parameter
thresholds are set to show degraded performance by generating a
defined notification from changes in parameter values. The thresholds
are set relative to the baseline value. The baseline value can be
established automatically or manually via externally initiated user
command. The baseline value is displayed in the PM report, next to
the currently measured value, in dBm.
