Loss of signal  
Ch1  
O
Loss Of Signal (LOS) indication for each  
channel, as determined by insufficient pulse  
density. Signal loss detected when RLOS =  
1. An LOS will be asserted when 175 ±75 0s  
occur in a row and deasserted when the  
pulse density is between 28% and 33%  
(DS3/STS-1) (i.e., a 1s density).
