Description
dsx1LoopbackConfig
(dsx1ConfigEntry 9 )
Specifies the loopback
state of the T1 interfaces.
Supports only the following
values:
dsx1NoLoop(1) – The T1/
DSX interface is not in a
loopback state.
dsx1PayloadLoop(2) – A
payload loopback (PLB) is
active for this T1/DSX
interface.
dsx1LineLoop(3) – A line
loopback (LLB) is active for
this T1/DSX interface.
dsx1OtherLoop(4) – A
repeater loopback (RLB) is
active for this T1/DSX
interface.
dsx1LineStatus
(dsx1ConfigEntry 10 )
Specifies the line (alarm)
status of the T1 interfaces.
More than one value can be
active at the same time.
When this is the case, the
value returned will be the
sum of the conditions.
Supports only the following
values:
dsx1NoAlarm(1) – No alarm
present.
dsx1RcvFarEndLOF(2) – A
yellow alarm signal is being
received.
dsx1RcvAIS(8) – An alarm
indication signal (AIS) is being
received.
dsx1LossOfFrame(32) – An
out of frame condition persists
for more than 2.5 seconds
(i.e., Red alarm).
dsx1LossOfSignal(64) – A
loss of signal condition
persists for more than
2.5 seconds (i.e., Red alarm).
dsx1LoopbackState(128) –
The near end of the T1
interfaces is in a loopback
state.
dsx1OtherFailure(4096) – An
excessive error rate (EER) is
detected on the network T1
interface.
dsx1SignalMode
(dsx1ConfigEntry 11 )
Supported as read-only.
Specifies whether Robbed
Bit Signaling (RBS) is in
use.
Supports only the following
values:
none(1) – No signaling is in
use on this interface.
robbedBit(2) – Robbed bit
signaling is being used on at
least one DS0 on this T1
interface.
