Description: This variable indicates the Line Status of the interface. It contains loopback, failure, re- ceived 'alarm' and transmitted 'alarm' infor- mation.

-- The dsx1LineStatus is a bit map represented as a sum, -- therefore, it can represent multiple failures (alarms) and -- a LoopbackState simultaneously.

-- dsx1NoAlarm should be set if and only if no other flag is -- set.

-- If the dsx1LoopbackState bit is set, the loopback in ef- -- fect can be determined from the dsx1LoopbackConfig object.

-- The various bit positions are: -- 1 dsx1NoAlarm No Alarm Present -- 2 dsx1RcvFarEndLOF Far end LOF (a.k.a. Yellow Alarm) -- 4 dsx1XmtFarEndLOF Near end sending LOF Indication -- 8 dsx1RcvAIS Far end sending AIS -- 16 dsx1XmtAIS Near end sending AIS -- 32 dsx1LossOfFrame Near end LOF (a.k.a.
