Bit Error Set Up fields. These sections are display-only fields that

 

 

 

 

 

are only displayed when the line code setting is INTERNAL. The

 

 

 

 

 

Status field always shows the current status if the line code is

 

 

 

 

 

INTERNAL, but the Error Counts and Elapsed Time fields only

 

 

 

 

 

show a value when a measurement is being made.
