Selectors 1 and 5: CNG detection when sharing a modular wall socket with a telephone
These selectors determine whether or not the equipment detects a CNG signal when a line is
connected to a telephone sharing a modular wall socket with the equipment. Upon detection of
CNG signals by the number of cycles specified by these selectors, the equipment interprets CNG
as an effective signal and then starts FAX reception.
