Battery Low
Battery backup has reached an energy point insufficient to supply the unit with power.
Temperature High
The power supply card is getting too hot.
Temperature Critical
The power supply card temperature is so high that it may suffer damage.
DS3 Alarm Traps (Near-End Active and Standby Cards)
LOS
The controller card has lost the network Rx signal.
OOF
The controller card detects a framing loss from the network.
AIS
The controller card is receiving an AIS (blue) alarm condition from the network. AIS
alarms occur when consecutive 1010s are received in the information bits. This indicates
that
The controller card is receiving an AIS (blue) alarm condition from the network. This
alarm occurs when consecutive 1010s are received in the information bits, indicating
there is a transmission fault located either at or upstream from the transmitting terminal.
RAI
The controller card is receiving an RAI (yellow) alarm from the network. This alarm is a
signal sent back toward the source of a failed transmit circuit. The X-bits (X1 and X2) are
set to zero.
IDLE
The controller card detects an idle sequence from the network.
TX LOS
The controller card’s transmitter has failed.
XCV
The controller card is receiving excessive code violations, exceeding the threshold set by
the user. For more information, refer to
In/Out Test
The DS3 is going in and out of test (applies to the Active controller card only).
DS3 Alarm Traps (Far-End Active Cards)
LOS
The remote unit’s active controller card has lost the network Rx signal.
OOF
The remote unit’s active controller card detects a framing loss from the network.
AIS
The remote unit’s active controller card is receiving an AIS (blue) alarm condition from
the network.
RAI
The remote unit’s active controller card is receiving an RAI (yellow) alarm from the net-
work. This alarm is a signal sent back toward the source of a failed transmit circuit. The
X-bits (X1 and X2) are set to zero.
IDLE
The remote unit’s active controller card detects an idle sequence from the network.
DS3 Eqpt Fail SA
The remote unit’s active controller card is receiving a service-affecting equipment failure
message from the network.
DS3 Eqpt Fail NSA
The remote unit’s active controller card is receiving a non-service-affecting equipment
failure message from the network.
