Abstract

PURPOSE:To enable switching a connection mode from an origination side to a termination side by sending out an enciphering mode switching request signal and switching the mode automatically when information showing that the current connection mode of the termination side is an undesirable mode is received. CONSTITUTION:When an opposite station originates and an incoming call detection circuit 2 confirms incoming, a control part 10 makes a connection between A and C through a switching circuit 7. At this time, when the termination side is facsimile mode, that is reported through a mode information sending circuit 4. When the origination side requests for a telephone call mode, a code consisting of three predetermined numeric digits is inputted as a mode switching request signal, so a connection between A and D is made and a code discriminating circuit 5 checks its validity, when the code is normal, the origination side is informed of switching to the telephone call mode and then a connection between A and F is made. If a signal other than the normal code is inputted three times, a connection between A and B is made and the line is disconnected on the termination side. Switching from the telephone call mode to facsimile mode is performed under nearly the same operation control.
