Abstract

PURPOSE:To make convenient for the manufacture and use, by separating a coding/ decoding means and error control means circuitally and switching the use and no use of error control function by a switch. CONSTITUTION:When an error control function is not used, switches 16, 18 at the transmission side are selected to the contact (b). Further, when the error control function is used, the switches 16, 18 are selected to the contact (a). After the output of an encoder 14 is written in a transmission first-in and first-out memory 15 to some extent, a step control section gives a transmission instruction to a frame transmission section through the arrow A. On the other hand, if no error control function is used at the reception side, switches 24, 26 are selected to the contact (b). When the error control function is used, the switches 24, 26 are selected to the contact (a). When a demodulator 20 detects the reception signal, a reception instruction is given from the step control section, not shown, to a frame reception section 25 through the arrow B.
