LossOfSignal
The port has experienced a Loss of Signal (
LOS
), or Loss of Carrier. An
LOS
event occurs after 175 contiguous pulse positions with no pulses (10
absent pulses on
E1
ports). An
LOS
failure is cleared after the switch
observes a single pulse.
RcvLOMF
This port is receiving loss of multiframe (
LOMF
) alarms from the far-end
port. When a far-end
E1
port detects an out-of-multiframe condition, it
transmits a frame with the alarm indication bit set (in time slot 16) back to
the local
E1
port. This error is similar to a yellow alarm on
T1
ports.
LocalUA
This port is not available possibly because a cable is not attached.
Loopback
The port is currently in loopback mode. Loopback mode can be config-
ured through the
temod
command or dynamically activated through Facil-
ity Data Link (
ANSI T1.403
and
AT&T 54106
) or through loopback control
codes on a T1 port.
