IPC: H04Q1/32
Filed: 1990-07-27
Abstract: PURPOSE:To perform detection and reception with high accuracy by deciding whether or not two waveforms are set line symmetrically, and identifying the reception of a dial pulse with a dial pulse discrimination circuit. CONSTITUTION:When the dial pulse is sent from a terminal on one side to the one on the other side after the speech state of the terminals is set via an exchange, a transmission waveform is inverted at the break start/end point of the dial pulse at the terminal on the other side at a reception side, and line symmetric data is inputted to the dial pulse discrimination circuit 11. The dial pulse discrimination circuit 11 confirms the reception of the dial pulse after receiving the two output of a break timer 7 and a comparator 10, and performs the count operation of a counter 4. Thereby, it is possible to reduce erroneous recognition to the extent that the dial pulse can be handled as communication information.
