Abstract

PURPOSE:To perform rapid connection operation and also to stop an error signal by performing the connection operation at the point in time when a multifrequency signal is received and discriminated or when the end of the multifrequency signal is detected. CONSTITUTION:Extension telephone set 1 is connected to multifrequency receiver 5 by way of subscriber's circuit 2 and channel 4A in channel switch 3. When push buttons for dialing are depressed, a corresponding multifrequency signal is sent out and at the point in time when the start or ceasing of the multifrequency signal, multifrequency receiver 5 sends an actuation signal to central controller 6. For an mutual extension connection, the connection operation is performed without making sure of signal ceasing information on the dial digit of the dial signal and for main- wire origination, the signal ceasing information is confirmed to close the channel.
