Receive LOS Defect
Condition Declared
R/O
Receive LOS (Loss of Signal) Defect Condition Declared:
This READ-ONLY bit-field indicates whether or not the Receive Section
(within Channel_n) is currently declaring the LOS defect condition.
The Receive Section (of Channel_n) will declare the LOS defect condition, if
any one of the following conditions is met.
If the Digital LOS Detector declares the LOS defect condition (for DS3 or
STS-1 applications)
If the Analog LOS Detector declares the LOS defect condition (for DS3 or
STS-1 applications)
If the ITU-T G.775 LOS Detector declares the LOS defect condition (for
E3 applications).
0 - Indicates that the Receive Section of Channel_n is NOT currently declar-
ing the LOS Defect Condition.
1 - Indicates that the Receive Section of Channel_n is currently declaring
the LOS Defect condition.
0
Transmit DMO Con-
dition Declared
R/O
Transmit DMO (Drive Monitor Output) Condition Declared:
This READ-ONLY bit-field indicates whether or not the Transmit Section of
Channel_n is currently declaring the DMO Alarm condition.
As configured, the Transmit Section will either internally (via the TTIP_n
and TRING_n ) or externally (via the MTIP_n and MRING_n) check the
Transmit Output DS3/E3/STS-1 Line signal for bipolar pulses. If the Trans-
mit Section were to detect no bipolar for 128 consecutive bit-periods, then it
will declare the Transmit DMO Alarm condition. This particular alarm can be
used to check for fault conditions on the Transmit Output Line Signal path.
The Transmit Section will clear the Transmit DMO Alarm condition upon
detecting bipolar activity on the Transmit Output Line signal.
0 - Indicates that the Transmit Section of Channel_n is NOT currently
declaring the Transmit DMO Alarm condition.
1 - Indicates that the Transmit Section of Channel_n is currently declaring
the Transmit DMO Alarm condition.
