Abstract

PURPOSE:To enable the communication among various terminal units through high quality of transmission error rate for the new service signal, by transmitting the signal in packet multiplexing of the new service signal at the pause of audio signal. CONSTITUTION:The audio input connected to the terminal 1 is converted into digital signal at the analog digital conversion circuit 3 and given to the time sharing multiplex circuit 6 via the gate circuit 4 and the delay line 5. On the other hand, various new service signal inputs connected to the terminal 2 are given to the temporary storage circuit 8 and the output is given to the packet multiplex circuit 9. When the pause of the audio input is detecteed with the pause detection circuit 10 connected to the terminal 1, the new service signal input is in packet multiplexing and transmitted at the pause location of the digital signal of audio signal and transmitted on the transmission line 11 with multiplex at the time sharing multiplex circuit 6.
