LS loopback A low-speed receive signal from a
high-speed line is electronically looped back
to the transmit signal for the high-speed line.
Signals coming from the low-speed
cross-connect panel are preempted by the
loopback.
Likely cause: Operate-Loopback has been
executed.
LS manual switch A low-speed slot was switched to protection
with a priority of "manual switch."
LSSW failure Failure of LSSW circuit pack.
LSSW removed LSSW circuit pack is missing from slot.
multiple DS-NEs defined Two or more network elements in a ring
network have their “Directory Server”
(DS-NE) parameter provisioned to “Yes.”
There must be one and only one DS-NE in
theringnetwork.
NE status comm failure The NE is not associated with an AGNE or
the AGNE cannot establish associations
with all of the NEs in the alarm group. If the
AGNE loses power, all NEs in the alarm
group will report this condition; however, the
condition may not be reported for several
minutes.
node ID conflict This normally indicates a transient condition
at the local network element.
non-preemptible protection access The Low Speed Shelf - Complementary is
connected to the protection line during the
switching function and cannot be
preempted by an automatic switch to
protection.
OC3 auto switch at far end An automatic line protection switch is active
at the far end of the OC-3 line.
OC3 auto switch at near end An automatic line protection switch is active
at the near end of the OC-3 line.
OC3 INTFC failure Failure of OC3 circuit pack.
OC3 INTFC removed OC3 circuit pack is missing from slot.
OC3 forced switch at far end An automatic line protection switch is active
with the priority of "forced switch" at the far
end of the OC-3 line.
