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 acDs3NoAlarm must be set if and only if no
other flag is set.
If the acDs3ConfigloopbackState bit is set, the loopback in effect can
be determined from the acDs3loopbackConfig 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
