Table 6-40. Alarm Conditions
Condition Description
None Indicates no alarms are currently being received.
RAI Indicates the MX3216 system is receiving a Remote Alarm Indication
(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.
LOS Indicates the MX3216 system has lost the Rx signal.
AIS Indicates the MX3216 system is receiving an Alarm Indication Signal
(AIS) (blue) alarm from the network. AIS alarms occur when
consecutive 1010s are received in the information bits. This indicates
there is a transmission fault located either at the transmitting terminal
or upstream from the transmitting terminal.
OOF Indicates the MX3216 system detects a framing loss from the network.
XCV Indicates the MX3216 system is receiving excessive code violations
from the network, which are exceeding the threshold set by the XCV
Threshold parameter.
IDLE Indicates the MX3216 system detects an idle sequence from the
network. Service is immediately available for use.
FEAC Indicates the MX3216 system is receiving an alarm from the far end
DS3 system.
