OPERATION
When bit errors are not detected, BIT ERR and
ERR SEC results remain at zero and SYNC SEC
indicates the number of seconds the synchronized
pattern was received and monitored for errors. Each
synchronized pattern is monitored for 175 seconds
during each cycle of the MULTIPAT test.
The BIT ERR result equals the sum of the five
MULTIPAT test pattern bit errors. The ASYN E
SEC result equals the sum of the five MULTIPAT
test pattern errored seconds. If pattern synchroniza-
tion is lost, SYNC SEC results are not counted.
