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 declaring the LOS Defect Condition.
1 - Indicates that the Receive Section of Channel_n is cur-
rently declaring the LOS Defect condition.

Condition Declared

0
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.
If configured accordingly, the Transmit Section will either
internally or externally check the Transmit Output DS3/E3/
STS-1 Line signal for bipolar pulses via the TTIP_n and
TRING_n output signals. If the Transmit Section were to
detect no bipolar for 128 consecutive bit-periods, then it
will declare the Transmit DMO Alarm condition. This par-
ticular 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 the instant that it detects some 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 condi-
tion.
1 - Indicates that the Transmit Section of Channel_n is cur-
rently declaring the Transmit DMO Alarm condition.
