Abstract

PURPOSE:To transmit and receive a control signal only as required and to improve data transmission reception speed by adopting the constitution such that a data/control identification signal is added to a transmission signal the result is sent as one-channel transmission data or received. CONSTITUTION:A data transmission section 101 adds a data/control identification signal to a transmission data and sends the result to a destination. Thus, the transmission data comprising a data signal and a data identification signal is sent. On the other hand, when no transmission data exists or a control signal is required to be sent, the control signal and the control identification signal are sent under the control of a control section 104. A data reception section 103 receives a data at the reception, the data/control identification signal of the reception signal is checked and whether the received signal is the data signal or the control signal is discriminated. In the case of the data signal, the reception data is sent to a terminal transmission data conversion section 102 and in the case of the control signal, the signal is used for controlling the inside of the said transmitter or controlling a terminal equipment.

The terminal reception data conversion unit 100 receives data from a low-speed terminal (not shown)! 01 is received, and when the designated number of bits is received, it is converted into high-speed data and sent to the data sending unit 101. Data sending section 101 adds a data/control identification signal to the transmission data and sends it to the other party. Therefore, a data identification signal is also sent to the transmission data at the same time as the data signal. On the other hand, if there is no data to send! If it is necessary to send out a control signal or a control signal, a control signal and a control identification signal are sent out under the control of the control unit 104.
