This variable indicates the
Line Status of the interface.
It contains loopback state information
and failure state information.
The dsx3LineStatus is a bit map represented
as a sum, therefore,
it can represent multiple failures
and a loopback (see dsx3LoopbackConfig object
for the type of loopback)
simultaneously.
The dsx3NoAlarm should be set if and only if
no other flag is set.
The various bit positions are:
1 dsx3NoAlarm No alarm present
2 dsx3RcvRAIFailure Receiving Yellow/Remote
Alarm Indication
4 dsx3XmitRAIAlarm Transmitting Yellow/Remote
Alarm Indication
dsx3RcvAIS Receiving AIS failure state
16 dsx3XmitAIS Transmitting AIS
32 dsx3LOF Receiving LOF failure state
64 dsx3LOS Receiving LOS failure state
128 dsx3LoopbackState Looping the received signal
256 dsx3RcvTestCode Receiving a Test Pattern
512 dsx3OtherFailure any line status not defined
