DS3 Alarm Traps (Near-End Active and Standby Cards)
Trap
If enabled, the unit issues a trap when...
LOS
the controller card has lost the network Rx sig-
nal.
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 there is
a transmission fault located either at or up-
stream 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. Service is immediately avail-
able for use.
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 (see
XCV Threshold on page 3-4).
In/Out Test
the DS3 is going in and out of test (applies to
the Active Controller Card only).
