3.5.1.5 Line separator
Line separators are electronic switches which isolate the defective part in case of a
short-circuit on the FDnet/C-NET detector line. The rest of the detector line remains
serviceable. On a loop line all FDnet/C-NET devices remain fully functional after a
simple error.
The function of the line separator is integrated in communication transponder
FDCC221S.
