Abstract

PURPOSE:To make it possible to transmit simultaneously voice and data and make it possible to eliminate troubles such as economic disadvantage, deterioration of use efficiency and a large delay by inserting data to voice information as required. CONSTITUTION:The output of transmitter 11 is connected to A/D converter 12, and the output is branched and supplied to parallel-series converter 13 and selector 14. Meanwhile, the output of data terminal 15 is stored in buffer memory 17 through interface 16. Memory 17 is controlled by clock pulse generator 18 and gates 19 and 20, and FF circuit 21 is set by the output of memory 17 and is reset by timer 22. FF circuit 21 is connected to not only selector 14 and differentiating circuit 23 but also one input terminal of gate 20 through delay circuit 24. Parallel-series converter 13 and differentiating circuit 23 are connected to unipolar/bipolar converter 25, and the output of converter 25 is transmitted to the subscriber's line.
