A LOS alarm (red alarm) will be detected if the incoming data stream
has no transitions for a programmable number T consecutive pulse
positions. The number T is programmable via the PCD register and
can be calculated as follows:
T= 16(N+1) ; with 0 =< N =< 255.
The maximum time is: 256
pulse will reset the internal pulse counter. The counter will be clocked
with the receive clock RCLK.
A LOS alarm (red alarm) will be cleared if a pulse density is detected
in the received bit stream.The number of pulses M which must occur
in the predefined PCD time interval is programmable via the PCR
register and can be calculated as follows:
M = N+1 ; with 0 =< N =< 255.
The time interval starts with the first detected pulse transition. With
every received pulse a counter will be incremented and the actual
counter is compared with the contents of PCR register. If the pulse
number >= the PCR value the LOS alarm will be reset otherwise the
alarm will still be active. In this case the next detected pulse transition
will start a new time interval.
Additional Loss of Signal recovery conditions may be selected by
register LIM2.LOS2/1.
