dx1LineStatus { dsx1Config
Entry 10 } read-only “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
8 dsx1RcvAIS
Far end sending AIS
16 dsx1XmtAIS
Near end sending AIS
32 dsx1LossOfFrame
Near end LOF (a.k.a.,
Red Alarm)
64 dsx1LossOfSignal
Near end Loss Of Signal
128 dsx1LoopbackState
Near end is looped
256 dsx1T16AIS
E1 TS16 AIS

Near End Sending TS16
LOMF
2048 dsx1RcvTestCode
Near End detects a test
code
4096 dsx1OtherFailure
any line status not
defined here”
Returns a sum of the
following
dsx1NoAlarm(1) - the unit
has no alarms.
dsx1RcvFarEndLOF(2) -
the unit is receiving a
yellow alarm from the far
end.
dsx1XmtFarEndLOF(4) -
unit is transmitting a
yellow alarm.
dsx1RcvAIS(8) - the unit
is receiving AIS from the
far end.
dsx1XmtAIS(16) - not
applicable.
dsx1LossOfFrame(32) -
unit is currently in an OOF
condition.
dsx1LossOfSignal(64) -
the unit is currently in a
LOS condition.
dsx1LoopbackState(128) -
the unit has a loop active
dsx1T16AIS(256) - not
applicable.
dsx1RcvFarEndLOMF
(512) - not applicable.
dsx1XmtFarEndLOMF
(1024) - not applicable.
dsx1RcvTestCode(2048) -
not applicable.
dsx1OtherFailure(4096) -
not applicable.
