Standing Conditions
LOM-LP (Path LO-Loss Multiframe)
The corresponding SNMP name for this condition is “lossofMultiframeLowerOrderPath”.
AIDTYPE Default
Severity
Probable Cause Suggested Corrective Action
VC3 CR The receiver is unable to verify
a correct sequence of values
in the multi-frame alignment
signal for the path
demultiplexed from the
incoming (network side)
signal.
The most likely causes of this
condition are a degraded signal
or a failure of the upstream
equipment originating the
signal.
1 Verify that both the near-end and far-end
facilities are provisioned correctly and are in-
service normal (“In Service”), and that the far-
end associated client facility is provisioned
correctly and is in-service normal (“In
Service”).
2 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).
3 Verify that the incoming 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, plug or module, as
appropriate, depending upon the cause
determined from the physical examination.
4 Verify that a signal is present at the cable
termination and that the signal conforms to the
required specifications (e.g. minimum and
maximum power levels). 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.
5 Replace the near-end plug supporting the
facility.
6 Replace the far-end plug supporting the
facility.
7 Replace the near-end module supporting the
facility.
8 Replace the far-end module supporting the
facility.
