Enter the B-channel from the keypad
(first press
<Del.>
) or use the cursor
keys to set the B-channel.
The ARGUS will display the B-channel
used and the duration of the leased line
(in h:min:sec).
Alternatively, the connection can be setup via Connection in the Single tests menu.
14.17.2 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 251).
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 250, Parameter settings page 251), however, you need not enter call
numbers or select a service.
In the case of a connection in end-to-end
mode (see page 251 and page 258), it is
also possible to run a BERT in the D-
channel HDLC framing (channel
selection: D-channel).
