acLogicalDs1ConfigLineStatus 1.3.6.1.4.1.2785.2.4.2.1.1.15

This variable indicates the Line Status of the interface. It contains loopback, failure, received 'alarm' and transmitted 'alarms information. The ds1LineStatus is a bit map represented as a sum, therefore, it can represent multiple failures (alarms) and a LoopbackState simultaneously. ds1NoAlarm must be set if and only if no other flag is set. If the ds1loopbackState bit is set, the loopback in effect can be determined from the ds1loopbackConfig object. The various bit positions are: 1 ds1NoAlarm No alarm present 2 ds1RcvFarEndLOF Far end LOF (a.k.a., Yellow Alarm) 4 ds1XmtFarEndLOF Near end sending LOF Indication 8 ds1RcvAIS Far end sending AIS 16 ds1XmtAIS Near end sending AIS 32 ds1LossOfFrame Near end LOF (a.k.a., Red Alarm) 64 dsLossOfSignal Near end Loss Of Signal 128 ds1LoopbackState Near end is looped 256 ds1RcvFarEndLOMF Far End Sending TS16 LOMF 512 ds1XmtFarEndLOMF Near End Sending TS16 LOMF 1024 ds1RcvTestCode Near End detects a test code 2048 ds1OtherFailure any line status not defined here 4096 ds1UnavailSigState Near End in Unavailable Signal State 16384 ds1NetEquipOOS Carrier Equipment Out of Service
