The BERT can be performed in three different ways:
1.
BERT in an extended self call
A remote number is not needed, since the ARGUS sets up the PRI 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 32 BERT wait) A bit pattern is sent to this remote tester.
Independent of the received bit pattern, the remote tester uses the same algorithm
to generate the bit-pattern that it sends back. Therefore, both directions are tested
independently.
