Abstract

PURPOSE:To respond to a main trunk incoming call without requiring a long time, by making a subscriber of extension response to the call, when the main trunk incoming call is in a waiting conditon for a prescribed time or longer. CONSTITUTION:While the operator processes an advance incoming call, when a timer 11-0 reaches a set time, the timer 11-0 outputs ''1''. In this case, a section 16-0 outputs ''1'' to turn on an AND circuit 12-0 and sets an FF 13-0 for information. As a result the FF 13-0 outputs ''1'', the output energizes an operation coil 18-0 of a relay 18via an OR circuit 14. Thus, a contact 18-1 is closed and the presence of a main trunk 1-0 to which no subscribers 4-0-4-n are responded is informed with a bell 8 through a power supply 19. Thus, when a subscriber, e.g., 14-1 dials a specific number, a controller 5 connects the trunk 1-0 with the subscriber 4-1 to enable to response to the subscriber 4-1.
