3 Connect the other end(s) of the adaptor cable to the test access point.
You have finished connecting the cables.
Performing a bit error rate test (BERT) involves configuring the test settings,
including logic error insertion; connecting the E1/Datacom Tester to the a
circuit; starting the test and inserting logic errors; and observing the results.
To do a bit error rate test
1 Set the test mode to DTE or DCE Emulation. See
mode" on page 53.
2 Select a pattern. See
3 Specify the other settings on the Configuration menu, as needed.

– Bit Error Multi Insert — inserts multiple bit errors with each press
(appears only if the Rate Type is set to "Multiple").
– Bit Error Insert — inserts one bit error with each press (appears only if
the Rate Type is set to "Single").
