Bit Error Rate Test
There are a number of variants of the bit error rate test: In the simplest case, a B channel
loop will be set up at the remote end; for information on parameter settings, see page 217.
After selection of the channel to be tested (B channel or D channel), the ARGUS will send
the test pattern, receive it back and evaluate it accordingly.
The displays and operation are, in largest part, similar to those of a BERT on a dial-up
connection (see page 216, Parameter settings, page 218), however, you need not enter
call numbers or select a service.
In the case of a BRI in end-to-end mode
(see page 217 and page 224), it is also
possible to run a BERT in the D channel
with HDLC framing (channel selection:
D channel).
