Analog LOS Defect
Declared
R/O
0
Analog LOS Defect Declared:
This READ-ONLY bit-field indicates whether or not the
Analog LOS (Loss of Signal) detector is declaring the LOS
Defect condition.
For DS3 and STS-1 applications, the Analog LOS Detector
will declare the LOS Defect condition whenever it deter-
mines that the amplitude of the pulses (within the incoming
DS3/STS-1 line signal) drops below a certain Analog LOS
Defect Declaration threshold level.
Conversely, (again for DS3 and STS-1 applications) the
Analog LOS Detector will clear the LOS Defect condition
whenever it determines that the amplitude of the pulses
(within the incoming DS3/STS-1 line signal) has risen
above a certain Analog LOS Defect Clearance threshold
level.
It should be noted that, in order to prevent "chattering"
within the Analog LOS Detector output, there is some built-
in hysteresis between the Analog LOS Defect Declaration
and the Analog LOS Defect Clearance threshold levels.
0 - Indicates that the Analog LOS Detector is NOT declar-
ing the LOS Defect Condition.
1 - Indicates that the Analog LOS Detector is currently
declaring the LOS Defect condition.

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.
