ARGUS 3u plus/3u NT
SES821 Severely Errored Seconds
The number of seconds in which the bit error rate is
>10
-3
. In one second, 64,000 bits are transferred,
thus BitERror=10
-3
equates to 64 bit errors.
US Unavailable Seconds
The number of sequentially adjacent seconds (at
least 9 sec) in which BER>10
-3
.
AS Available Seconds
The number of sequentially adjacent seconds (at
least 9 sec) in which BER<10
-3
.
DM Degraded Minutes
The number of minutes in which the bit error rate is
>10
-6
.
In one minute, 3,840,000 bits are transferred, thus a
BER = 10
-6
corresponds to 3.84 bit errors (3 errors =
NO (no DMs), 4 errors = OK (DM)).
LOS Loss of Synchronisation
Synchronisation is lost at an error rate > or = 20%
within a second. The absolute number of
synchronisation losses will be shown.
