Digital LOS Defect
Declared
R/O
0
Digital LOS Defect Declared:
This READ-ONLY bit-field indicates whether or not the
Digital LOS (Loss of Signal) detector is declaring the LOS
Defect condition.
For DS3 and STS-1 applications, the Digital LOS Detector
will declare the LOS Defect condition whenever it detects
an absence of pulses (within the incoming DS3 or STS-1
data-stream) for 160 consecutive bit-periods.
Further, (again for DS3 and STS-1 applications) the Digital
LOS Detector will clear the LOS Defect condition when-
ever it determines that the pulse density (within the incom-
ing DS3 or STS-1 signal) is at least 33%.
0 - Indicates that the Digital LOS Detector is NOT declaring
the LOS Defect Condition.
1 - Indicates that the Digital LOS Detector is currently
declaring the LOS Defect condition.
NOTES:
1.
LOS Detection (within each channel of the
XRT75R03) is performed by both an Analog LOS
Detector and a Digital LOS Detector. The LOS
state of a given Channel is simply a WIRED-OR
of the LOS Defect Declare states of these two
detectors.
2.
The current LOS Defect Condition (for the
channel) can be determined by reading out the
contents of Bit 1 (Receive LOS Defect Declared)
within this register.
