Abstract

PURPOSE:To attain efficient incoming response control by setting an optimum call time to each communication terminal equipment in responding to the installation environment and applying callout control based on the setting time so as to an undesired long time call or undesired waiting of the caller. CONSTITUTION:In receiving the detection notice of a call signal from a trunk circuit 36, a central controller 31 controls a voice interface 34 to send a call signal to a pushbutton telephone set 1 of the 1st extension. When the telephone set 1 is hooked off within the setting time of a timer 14 and a response comes, a switch circuit 35 is controlled to generate a DC loop to an external line having a call for the reply and the loop is connected to the 1st extension to form a channel. On the other hand, when a timeout is informed from the telephone set 1, the call to the telephone set 1 is stopped and a call signal is sent to the next button telephone set 2 being the end extension newly to apply the similar operation. When a timeout is informed also from the telephone set 2, the transmission of the call signal to the telephone set 2 is stopped. Thus, the external line incoming control of the floating in-line system is executed.
