Record the number of Rx bit errors.
Note: In the example in step 48, the number of bit errors received appears
to the right of Rx bit errors.
50
To inject bit errors, type
>INJERR link_no
and press the Enter key.
where
link_no
is the number of the link you tested in step 39
Example of a MAP response:
51
To display the result of injecting bit errors, type
>QUERY link_no PR
and press the Enter key.
where
link_no
is the number of the link that you want to test (0 to 15)
Example of a MAP response:
If the response is
Do
Link 1: INJECT ERROR
completed
step 51
Link n:Failed - C7BERT is not
active on this link
step 39
anything else
step 78
If the response is
Do

step 52
anything else
step 78
