For example, if the crypto resync level "time-out-period" is 2
20
(1,048,576 bit
times) and the bit rate is 1.2-Kbps (1,200 bits per second or 8.3 microseconds per
bit) then the time out period equals 874 seconds. In this extreme example the
VersaMux-4000 resync pulse would expire before the time out period and the
resync would not occur.
At a 128 kbps rate and using 2
20
bit times, the time out period would be 8
seconds (too long for the resync to occur). Using 2
10
bit times the time out period
is 8 milliseconds which may or may not be long enough to initiate the resync.
NOTE:
To ensure that the VersaMux-4000 resync pulse is long enough for all bit rates, we
recommend that you set (strap) the crypto to the 2
0
(one bit time) resync level
"time-out-period".
