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 Sec-
tion (within Channel_n) is currently declaring the LOS defect condition.
The Receive Section (of Channel_n) will declare the LOS defect condi-
tion, 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
declaring the LOS Defect Condition.
1 - Indicates that the Receive Section of Channel_n is currently declar-
ing the LOS Defect condition.
0
Transmit DMO
Condition Declared
R/O
Transmit DMO (Drive Monitor Output) Condition Declared:
This READ-ONLY bit-field indicates whether or not the Transmit Sec-
tion 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 Transmit Section were to detect no bipolar for 128 con-
secutive bit-periods, then it will declare the Transmit DMO Alarm condi-
tion. 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.
