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. If these se-
lectors are set to "0,0," the equipment does not detect CNG. If set to other selector values,
the equipment interprets CNG as an effective signal upon detection of CNG signals by the
number of cycles specified by these selectors and then starts FAX reception.
