ABSTRACT:
A switching apparatus is proposed which automatically switches between a telephone set connected to a telephone line and a terminal device for data communication in accordance with a signal sent through the telephone line. When an incoming call signal is detected, the telephone lines are engaged with the telephone set, and a response signal is sent out onto the telephone line. Thereafter, when a control signal or the like is received by the switching apparatus, the terminal device is automatically engaged with the telephone line. When the control signal is not sent to the switching apparatus, the called party can communicate with the calling party when the telephone set is set in the off-hook state.
