Abstract

PURPOSE:To increase the rate of call achievement at emergency call, by providing a means which stops the callout automatically without hooking on of a handset by a caller at non-response of a called party, and a means which makes call out sequentially and automatically until one of a called party group responds. CONSTITUTION:When a caller A dials a called party B, the caller A and the called party B are connected via a special intra-office trunk SIOT. In this case, no restoration information is transferred from the marker MKR to an outgoing register OR, which is held. If the called party B does not respond, a relay TM is activated with a non-response monitor timer circuit, and a restoration information is given from the register OR to the trunk SIOT and an advance relay ADV1 and the marker MKR are started. Thus, the caller A and a called party C are connected via the trunk SIOT, allowing to call out the called party C, until the caller A is restored, the called party C responds or the non-monitor timer circuit is activated.
