19 Operation on an ISDN Access
ARGUS 152

The BERT can be performed in three different ways:
BERT Parameter Configuration
ARGUS - Main Menu
The procedure for configuring a parameter
will be illustrated with a single example.
The default settings can be restored at any
time (see page 361).
1.
BERT in an extended call to oneself
A remote number is not needed, since the ARGUS sets up the ISDN connection to
itself. In this case, the ARGUS requires two B channels for the test.
2.
BERT with a loopbox
A loopbox (e.g. another member of the ARGUS family of testers at the remote end)
is required. The test uses one B channel.
3.
BERT end-to-end
This test requires a waiting remote tester (e.g. a second ARGUS in the "BERT wait"
mode)(see page 224, BERT wait)
A bit pattern is sent to this remote tester.
Independent of the bit pattern received, the remote tester will use the same
algorithm to generate the bit pattern that it sends back. Therefore, both directions
are tested independently.
The ARGUS sets the value
entered as the default BERT time
and returns to the next higher
menu.
