Bit Error Rate Test - Intec ARGUS Manual

4 Operation on a PRI Access

4.13.2 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. Parameter settings (see page 25).
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, you simply need not enter call numbers or select a service.


In the case of a PRI access in end-to-end
mode (see page 59), a BERT can be run: 
- in the D-channel
- in a B-channel
(Select channel: B-channel (64k))
- in two B-channels 
(Select channel: B-channel (128k))
- MegaBERT framed 
(optional: in all B-channels and in the
D-channel)
- MegaBERT unframed 
(optional: all B-channels, the D-channel
and time slot 0).
