Table B – RTRV-ALM Message Descriptions
Description
Alarm
Level Meaning
–48V power/fuse FA|FB failed
MN A –48 volt power feeder or a fuse on the user panel
has failed. (
FA
or
FB
LED identifies failure.)
AC power failed
PMN The AC power supply to a remote terminal cabinet
has failed.
ACO active
Status The parallel telemetry outputs and audible office
alarms normally active due to the alarm conditions
in the system are being suppressed. (See the
opr-aco
command.)
AGNE communication failure
MJ A remote network element (NE) cannot establish
and NE status association with an alarm gateway
network element (AGNE). The alarm is also
declared by an AGNE that can not establish an NE
status association with one or more NEs in its
alarm group.
Likely cause:
The AGNE has not been assigned in
an alarm group. The AGNE and NEs are assigned
different alarm group numbers.
APS - automatic lock
MN The service associated with a
DS1
,
DS1PM
, or
T1EXT
circuit pack has been automatically
switched and locked onto the protection
DS1
,
DS1PM
, or
T1EXT
circuit pack. The automatic
protection switching (APS) lock will remain active
until midnight.
Likely cause:
Four automatic switches of a single
DS1
,
DS1PM
, or
T1EXT
circuit pack in 10 minutes,
probably because of an intermittent failure of the
DS1
,
DS1PM
, or
T1EXT
circuit pack.
APS channel failed
MN The SONET Automatic Protection Switching (APS)
channel on the protection OC-3 line has failed.
Likely cause:
Failure of the
OLIU
circuit pack on
the protection line (
MAIN-2(P)
at the far end or
failure of the
OLIU
circuit pack on the protection
line (
MAIN-2(P)
) at the near end.
