Loss of Signal
DS3/STS-1
AK2504A detects the loss of signal by analog and digital methods. Loss of Signal function in DS3/STS-1 mode is
as follows.
Analog Loss of Signal(ALOS)
Analog loss detector operates as follows.
-
Analog loss detector monitors the peak level of the incoming signal.
-
If the peak level falls below Alarm set threshold as shown in Table 14, output pins status is shown in the
diagram below.

Notes:
-
Set Alarm Level is 0.5dB lower than Clear Alarm Level.
Digital Loss of Signal(DLOS)
Digital loss detector operates as follows.
-
A digital loss detector monitors consecutive 0s and 1s density in recovered data.
-
RLOS is set high if 175
±
5 consecutive 0s is detected.
-
RPDATA,RNDATA are set low if ALOS is detected.
-
RLOS is set low if 33% 1s density (58 1s in 175 consecutive bits) and no consecutive 100 0s are detected.
