Bit Error Rate Testing
You can use
Aurora Presto
to perform a Bit Error Rate Test
(BERT) to test the quality of the DSL copper pair line. There
are two BER tests: the physical layer BERT and the DSL
ATM BERT.
Software Compatibility
If you are using
Aurora Presto
to test a BERT pattern from
an
Aurora Jazz
