Description: This variable indicates the Line Status of the interface. It contains loopback state information and failure state information. The ds3LineStatus is a bit map represented as a sum, therefore, it can represent multiple failures and a loopback (see acDs3LoopbackConfig object for the type of loopback) simultaneously. The ds3NoAlarm must be set if and only if no other flag is set.

If the ds3loopbackState bit is set, the loopback in effect can be determined from the ds3loopbackConfig object. The various bit positions are: 1 ds3NoAlarm No alarm present 2 ds3RcvRAIFailure Receiving Yellow/Remote Alarm Indication 4 ds3XmitRAIAlarm Transmitting Yellow/Remote Alarm Indication 8 ds3RcvAIS Receiving AIS failure state 16 ds3XmitAIS Transmitting AIS 32 ds3LOF Receiving LOF failure state 64 ds3LOS Receiving LOS failure state 128 ds3LoopbackState Looping the received signal 256 ds3RcvTestCode Receiving a Test Pattern 512 ds3OtherFailure any line status not defined here 1024 ds3UnavailSigState Near End in Unavailable Signal State 2048 ds3NetEquipOOS Carrier Equipment Out of Service
