251 Line Status (dsx1LineStatus)
dsx1LineStatus OBJECT-TYPE
SYNTAX INTEGER (1..8191)
ACCESS read-only
STATUS mandatory
DESCRIPTION: This variable indicates the Line Status of the interface. It contains loopback, failure,
received ‘alarm’ and transmitted ‘alarm’ information.
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 effect 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

256 dsx1T16AIS E1 TS16 AIS
512 dsx1RcvFarEndLOMF Far End Sending TS16 LOMF
1024 dsx1XmtFarEndLOMF Near End Sending TS16 LOMF
