PURPOSE:To prevent the imcomplete connection during switching, by the connection and switching of the succeeding dial with minimum pause at the condition when the dial number signal after reception is finished for playback. CONSTITUTION:The dial number D produced from the outgoing subscriber 1 enters the outgoing register trunk 3 via the communication network 2 and it stored in the memory section M of the central control device 8 via the scanning circuit 4. The number D is reproduced at the outgoing sender trunk 9 via the information reception distributor 7 and the signal distributor 10. At the same time when the reproduction is finished, the end signal (e) is fed to the device 8 to be stored in the memory section M. With this state, when the device 8 receives the succeeding dial number, the dial number reproduced before ia transmitted to the channel via the outgoing trunk 5 through the terminals (c) and (d). |
