Standing Conditions
T-CDC-HT (CD Compensation-High)
The corresponding SNMP name for this condition is “dispersionCompensationTooHigh”.
AIDTYPE Default
Severity
Probable
Cause
Suggested Corrective Action
CH MN The chromatic
dispersion
compensation
adjustment
exceeds the
provisioned
threshold
value.
1 Verify that the facility is properly
configured and that it has been properly
set-up. If initial set-up has not yet been
completed, perform the facility set-up
process.
2 Verify that the threshold level is
provisioned correctly. Once the
threshold value is set correctly, perform
a manual chromatic dispersion
compensation adjustment operation on
the facility to reset the compensation
level.
3 Verify that the incoming cable is the
correct cable and that the transmit and
receive ports are connected to their
proper respective portions of the cable
(i.e. that the fibers are not swapped
between transmit and receive).
4 Verify that the incoming optical fiber is
firmly connected to the receive port
associated with the facility and that the
connector is not physically impaired by
obstructions, dirt or component damage.
Clean the connector or replace the cable
or plug, as appropriate, depending upon
the cause determined from the physical
examination.
5 Verify that a signal is present at the
incoming signal cable termination and
that the signal conforms to the required
specifications (e.g. minimum and
maximum power levels, span
attenuation/loss, fiber type, chromatic
dispersion, PMD). If the signal meets
the required specifications proceed to
the next step below, otherwise locate
the source of the signal problem
upstream and repair the problem.
6 Replace the module supporting the
facility.
