Setting up the network input
5. Set the alarm threshold in the loss field.
-3
Typically set to 10e . This value indicates too many bit errors for the signal to be
recovered from the transport stream. An alarm message is sent to ROSA if the
loss threshold is reached. If you have clicked automatic line switching the line
input automatically switches if the BER loss threshold is reached and an A-alarm
is issued.
6. Set the warning threshold in the degraded field.
-4
Typically set to 10e . This value indicates a degradation of the signal, but it can
still be recovered from the transport stream. An alarm message is sent to ROSA
if the degraded threshold is reached. You cannot set the threshold to a higher
value than the one selected for the loss threshold.
