Understanding the test results
During the test, aurora
Sonata
displays the error count (see
Performing BERT using a connected call earlier in this
section). If the call fails during the test, the test stops and
aurora
Sonata displays the Cause Code. When the test is complete,
aurora Sonata displays the final results.
BERT on the D channel
To test a Basic Rate fixed link you have the option to perform
BERT on the D channel as well as the standard B channel test.
Notes:
• Do not attempt to perform D channel BERT on a live
signalling line, as this could damage the operation of the
switch and put the line out of service.
• For fixed link testing you must set
L2 protocol
in the
Emulation Setup
menu to
No D Chan
. See Setting the
emulation mode in Chapter 3 section 1.
