DDM-2000 OC-3 M
ULTIPLEXER
inc. (from fiber) DS3
OOF
The system detects a DS3 out-of-frame condition in DEMUX
direction (coming from fiber) for the specified DS3 signal. This
condition is reported only if the DS3 interface is provisioned is VM
or VMR mode. See
set-t3:
or
rtrv-t3:
commands.
Likely causes: An OOF DS3 signal inc. to the DSX-3 at the far
end; or failure of DS3 circuit pack at near or far end; the DS3 signal
is looped at both ends. If no trouble with DSX-3 signal, replace DS3
circuit pack [DLP-523].
inc. EC1 FERF
The system has detected the EC-1 far end receive failure (FERF)
signal in the incoming EC-1 signal.
Likely causes: The other end has detected an incoming signal
failure on the specified EC-1 line. This may be caused by failure of
the STS1E or 3STS1E circuit pack at the near end, the STS1E or
3STS1E circuit pack at the far end, or the transmit cable on the
specified line. Replace STS1E or 3STS1E circuit pack at near end
and/or far end [DLP-523] or repair EC-1 cable.
inc. OC1 FERF
The system detects the OC-1 far end receive failure (FERF) signal
in the incoming OC-1 signal.
Likely causes: The far end has detected an incoming signal
failure on the specified OC-1 line. This may be caused by failure of
the OLIU circuit pack at the near end, the OLIU circuit pack at the
far end, or the transmit fiber on the specified line [TAP-119].
inc. OC3 FERF
The system detects the OC-3 far end receive failure (FERF) signal
in the incoming OC-3 signal.
Likely causes: The far end has detected an incoming signal
failure on the specified OC-3 line. This may be caused by failure of
the OLIU circuit pack at the near end, the OLIU circuit pack at the
far end, or the transmit fiber on the specified line [TAP-111] or
[TAP-119].
inc. OC12 FERF
The system detects the OC-12 far end receive failure (FERF)
signal in the incoming OC-12 signal.
Likely causes: The far end has detected an incoming signal
failure on the specified OC-12 line. This may be caused by failure
of the OLIU circuit pack at the near end, the OLIU circuit pack at
the far end, or the transmit fiber on the specified line [TAP-111] or
[TAP-119].
inc. STS1 yellow
The system detects an incoming STS-1 yellow signal inserted by
the far end path terminating equipment.
Likely causes: Incomplete or incorrect cross-connect provisioning
in the end-to-end network [TAP-120], or unprotected unidirectional
failure of the OLIU circuit pack or fiber at some point in the
end-to-end path.
inc. VT yellow
The far end is detecting VT AIS or VT LOP and inserting VT yellow
in its transmit signal.
Likely causes: Unprotected unidirectional failure of a circuit pack
or fiber at some point in the end-to-end path.
