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

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 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 (see XCV Threshold on page 3-11)

In/Out Test the DS3 is going in and out of test (applies to the

Active controller card only)
