Abstract

PURPOSE:To simplify the additional provision of a terminal device to a telephone terminal device by providing a means identifying the presence of the terminal device provided additionally to the telephone terminal device, transmitting and receiving a transmitted and received data to the terminal device when the additional provision of the terminal device is detected and processing the transmitted and received data when the additional provision of the terminal device is not detected. CONSTITUTION:An interface circuit 19 supervises whether or not a terminal device 3 is connected and informs the result of the said supervision to a processor 130. When the non-connection of the terminal device 3 from the interface circuit 19 is informed to the processor 130, the processor 130 transmits a data set to a shift register 131 to a modulation and demodulation circuit 17 and after the processor 130 stores the data transmitted from the modulation and demodulation circuit 17 to the shift register 131, the processor 130 applies required processing to the said data. On the other hand, when the connection of the terminal device 30 is informed from the interface circuit 19, after the processor 130 stores once the data transmitted from the modulation and demodulation circuit 17 to the shift register 131, the processor 130 transmits the data to the terminal device 3 via the interface circuit 19.

After the data transmitted from the shift register 131 is accumulated, the data is subjected to necessary processing. For example, when a line release signal is received, an instruction to open the loop for the telephone line 2 is transmitted to the telephone circuit 11, and when a retransmission request signal is received, the data accumulated in the storage circuit 16 is transferred to the modulation/demodulation circuit. 17
If the received data is to be displayed, it is transmitted to the display circuit 18, and processing based on the analysis is executed. On the other hand, interface circuit 1
9 that the terminal device 3 is connected, the processor 130 first supplies the data transmitted from the modulation/demodulation circuit 17 to the shift register 131, and then transmits the data to the terminal device 3 via the interface circuit 9. , and terminal device 3
The post-modification/reconstruction circuit 1 temporarily stores the data transmitted from the interface circuit 19 in the shift register 131.
7. During this time, the processor L30 does not perform any analysis or processing on the data stored in the shift register 131. In such a state, the terminal device 3 is able to send and receive large amounts of data as if it were directly connected to the telephone line 2, and all line opening and other processing can be deciphered by the device 3 and performed as necessary. For example, a request is made to operate the telephone terminal IO.
