SES821 Severely Errored Seconds
The number of seconds in which the bit error rate is
-3
>10
. In one second, 64,000 bits are transferred,
thus BitERror=10

Available Seconds
The number of sequentially adjacent seconds (at

DM
Degraded Minutes
The number of minutes in which the bit error rate is
-6
>10
.
In one minute, 3,840,000 bits are transferred, thus a
-6
BER = 10
corresponds to 3.84 bit errors (3 errors =
NO (no DMs), 4 errors = OK (DM)).
