Maintenance Description
9-20 Issue 8.0 July 2002
incoming OC3/OC12 SD A signal degrade (SD) condition has been
detected on an incoming OC-3/OC-12 line.
The line parity error rate threshold setting
has been exceeded (10
-5
through 10
-9
with
an original value of 10
-6
).
Likely causes: Failure of the far end
OC3/OC12 circuit pack or the local
OC3/OC12 circuit pack.
incoming OC3/OC12 SF A signal failure (SF) condition has been
detected on an incoming OC3/OC12 line.
Likely causes: Failure of the far end
OC3/OC12 circuit pack, the incoming
OC-3/OC-12 line (receive fiber), or the local
OC3/OC12 circuit pack.
OC12 mode conflict (equipment) The alarm condition that occurs when the
addressed slot or slot pair is provisioned for
1+1 mode and one or both slots are not in
the "equipped" state.
OC12 mode conflict (quad pair) The alarm condition that occurs when the
addressed slot or slot pair is provisioned for
1+1 mode and the other slot is provisioned
for 0x1 mode (in the same direction).
OC12 mode conflict (x-connect) The alarm condition that occurs when the
addressed slot, of the slot pair, is
provisioned for 1+1 mode and the two slots
are cross-connected to different tributaries.
Inconsistent DCC Values The OC-3 or OC-12 DCC orientation (user
or network) is the same at both ends of the
DCC, but should be different.
OC12 INTFC failure An OC12 circuit pack failure.
OC12 INTFC removed An OC12 circuit pack is missing from a slot.
OC12 auto switch at far-end An automatic switch has occurred at the
far-end.
OC12 auto switch at near-end An automatic switch has occurred at the
near-end.
OC12 forced switch at the far-end A forced switch has been performed on the
far-end.
OC12 forced switch at the near-end A forced switch has been performed at the
near-end.
OC12 inhibit at near-end Line protection switching is disabled at the
near end of the OC-12 line.
