Display of other characteristic values (in
accordance with ITU-T G.821)
All values are relative and given in
percentages.
The ARGUS evaluates whether the test
results satisfy the limits specified in the
CCITT G.821 with consideration of the
reference connection HRX (displaying OK
or NO).

-
The evaluation of the results depends on
the error threshold (in this example OK),
see page 252.

Transferred data
(K = 1024 bits, k = 1000 bits)
-
sync.time in h:min:sec
(The time in which the ARGUS can
synchronize to the bit pattern)
-
No. LOS (counter)
Synchronization is lost at error rates
greater than or equal to 20 % within a
period of a second.
The absolute number of synchronization
losses will be shown.
-
LOS time: Duration of the BERT minus
the synchronization time
(The time in which the ARGUS could not
synchronize to the bit pattern after it had
been in sync at least once)
-
abs. err.: The number of bit errors
-
rel. err:: The bit error rate
(e.g. 9.7E-07 = 9.7·10
-7
= 0.00000097)
