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