Table 6-41. Remote System Conditions
Condition Description
Normal Indicates the far end MX3216 system is not reporting any conditions.
DS3 RAI Indicates the far end unit 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.
DS3 LOS Indicates the far end unit has lost the Rx signal.
DS3 AIS Indicates the far end unit is receiving an Alarm Indication Signal (AIS)
(blue) alarm condition 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.
DS3 LOF Indicates the far end unit detects a framing loss, Loss of Frame (LOF),
from the network.
DS3 Idle Indicates the far end unit detects an idle sequence from the network.
DS3 Eqpt Fail (SA) Indicates the far end unit or network is reporting a service-affecting
(SA) DS3 equipment failure.
DS3 Eqpt Fail (NSA) Indicates the far end unit or network is reporting a non-service-
affecting (NSA) DS3 equipment failure.
Common Eqpt Fail Indicates the far end unit or network is reporting a non-service-
affecting common equipment failure.
Multiple DS1 LOS Indicates the far end unit is experiencing a loss of signal on multiple
DS1s.
Single DS1 LOS Indicates the far end unit is experiencing a loss of signal on a single
DS1.
DS1 Eqpt Fail (SA) Indicates the far end unit is experiencing a service-affecting DS1
equipment failure.
DS1 Eqpt Fail (NSA) Indicates the far end unit is experiencing a non-service-affecting DS1
equipment failure.
Unknown Indicates the unit is unable to discern the status of the far end unit.
(Normal state for M13 framing.)
