Explanation
You can use the keypad to enter measurement times ranging
from 1 minute to 99 hours and 59 minutes (= 99:59).
If the time is set to 00:00 (=BERT with unlimited
measurement time), the BERT will not stop
automatically. In this case, the BERT must be
terminated manually by pressing the
Default setting: 1 minute
This function is used to select the bit pattern to be sent
cyclically by the ARGUS to perform a BERT on a PRI access
(see "Bit patt. BRI/U").

-1= default setting).
This is the level used to evaluate whether the BERT had an
"acceptable" bit error rate.
If the BERT has a bit error rate, which exceeds this error level,
the ARGUS will display a "NO" as the test result.
Using the keypad, this parameter can be set to any value from
-01
01 (= 10
) to 99 (= 10
The default threshold (error level) is 10

evaluated as OK.
