365-575-783R1.1
Issue 1, June 2002
Use this procedure to clear the following alarm conditions:
•
OMS LOS: 0GHz and 100GHz offset at OA (preamp)
•
OMS LOS: 50GHz and 150GHz offset at OA (preamp)
These alarms are raised at the OA(Preamp) circuit pack when there is
a total loss of signal at it's IN_SIG port. This indicates an Optical
Multiplex Section (OMS) loss of signal (LOS) between the OUT ports
of the RP circuit pack and the IN_SIG port of the associated
OA(Preamp).
OMS LOS: 0GHz and 100GHz offset at OA (preamp)
when a LOS is detected at the IN_SIG port of the OA(Preamp)
associated with the 0/100 GHz channels at 10G and 40G End
Terminals.
OMS LOS: 50GHz and 150GHz offset at OA (preamp)
when a LOS is detected at the IN_SIG port of the OA(Preamp)
associated with the 50/150 GHz channels in the 10G End Terminal.
