Table B – RTRV-ALM Message Descriptions
Description
Alarm
Level Meaning
2nd CP required for BBF3/BBF8 CR or MN The BBF3/BBF3B DS1PM and BBF8 HDSL circuit
pack requires both corresponding FUNCTION
UNITS slots in the group to be equipped with
MXRVO or STS1E circuit packs. A second
MXRVO or STS1E circuit pack should be inserted
in the companion FUNCTION UNITS slot.
2nd CP reqd for BBF6/BBF9 CR or MN The BBF6 T1EXT and IMA LAN circuit pack
requires both corresponding FUNCTION UNITS
slots in the group to be equipped with MXRVO
circuit packs. A second MXRVO circuit pack
should be inserted in the companion FUNCTION
UNITS slot.
–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 circuit
pack has been automatically switched and locked
onto the protection DS1/DS1PM circuit pack. The
automatic protection switching (APS) lock will
remain active until midnight.
Likely cause: Four automatic switches of a single
DS1/DS1PM circuit pack in 10 minutes, probably
because of an intermittent failure of the
DS1/DS1PM circuit pack.
