Abstract

PURPOSE:To make a signal decision of high reliability by eliminating an error decision due to a noise similar to an information signal by connecting a receiving circuit to a channel only in minimum required time during information-signal reception. CONSTITUTION:After the existence of a coin is detected by inverting the polarity of a charging pulse, whether a loop is formed at the side of telephone set TEL is discrminated in a certain-time elapse at the point in time of TM-relay release; when the loop is formed, signal reception is made ready and when not, the loop is broken at the point in time of the release of relay TM without connecting a receiver. Then, relay A is not in operation, relay RECC never operates, and relay RL operates, so that the following processing operation will start. Since relay RECC will not operate, the connection of the receiver to the channel is prevented and the possibility that a similar signal is misjudged as a coin-receipt end signal is eliminated perfectly.
