<p>PURPOSE:To provide a remote system with a voice outputting means at low cost, by providing a center equipment side with a voice synthesizing means and a terminal equipment side with a voice signal amplifying means, and by transmitting and receiving data and voice alternately to and from a communication circuit. CONSTITUTION:The transmission and reception of data between a center equipment 1 and a terminal equipment 5 is performed under the control of the equipment 1 via the route of a transmission-reception controlling part 11, an MODEM 2, a signal switching device 4, a communication circuit L, a branching device 7, an MODEM6, and a transmission-reception controlling part 51. Under a command sent from the equipment 1 through a bus B, a voice output controller 3 synthesizes a voice by a RACOR voice output technique, etc., and while switching the device 4 to a voice signal VI by a switching signal S to send it to the circuit L, permits a speaker 39 to voice. At the terminal side, a voice output controlling circuit 8 receives a voice signal LO' branched by the device 7 and the signal LO' is amplified by a switching signal C1 from the equipment 5 under the command of the equipment 1, thereby driving a speaker 89. If the equipment 1 is impaired, a trouble detection signal F puts the controller 3 in operation to voice the trouble state, recovery state, etc.</p> |
