The [F1] Circuit Identifier lets you assign a name to the circuit if desired.
The [F3] Service Mode setting has two service modes which can select OOS (Out of Service) or IS (In
Service).
The [F3] Clock Source setting permits the use of an External clock source, or the Internal clock.
You can set the polarity of Tx or Rx clock to fit the requirement of different kind of DTEs.
