Trouble locating and clearing procedures (continued)
To start the C7BERT, type
>START link_no
and press Enter.
where
link_no
is the number of the link you want to test (0 to 15)
If the response
is Link n: C7BERT started
is Link n:Failed - Link state is
invalid for C7BERTLink must
be ManB and DAct (or LFS)
is other than listed here
To display the test results of the C7BERT, type
>QUERY link_no
and press Enter.
where
link_no
is the number of the tested link (0 to 15)
Example of a MAP response:
query 1
Link 1: C7BERT query

Rx Frames
Rx Bit Errors:
Bit Err Rate : 0 x 10–15
If the response
is a display of C7BERT statistics step 81

Determine if any transmitted Tx frames exist.
Note: The number of frames transmitted appears to the right of the Tx
Frames header of the MAP display. In the example in step 31, the number
of frames transmitted is 19 016 .
If Transmitted Tx Frames
are present
