Pulse Count Detection
A ’Loss of Signal’ alarm will be detected, if the incoming data stream has
zero octets for a programmable number T of consecutive octets. The
number T is programmable via the PCD register and can be calculated
as follows:
T = 8*(PCD+1), 1
E.g. PCD = 21 sets loss of signal threshold to 176 (=(21+1)*8) zeros.
Note: For T1 mode time detection interval has cumulative uncertainty
