Abstract

PURPOSE:To increase the rate of call achievement at emergency call, by providing a means which stops callout through additional dialing without hook-on of a handset by the caller, at non-response of a called party, and a means calling out a subscriber designated by the additional dialing. CONSTITUTION:When a caller A hooks up a handset and dials the number of a called party B, a marker MKR is started to make relay line call connection for the sender. The number of the called party is reproduced by the sender and the number is transmitted to an incoming register IR consisting of a relay line folding in the station. The register IR starts the marker MKR to discriminate an emergency call and connects an LD incoming trunk LDICT to the called party B while holding the register IR. If the called party B has not responded, when the caller A additionally dials a called party C, relaying is made with an LD outgoing trunk LDOGT, and the trunk LDICT releases the ring of the called party B and the connection to the called party C is made.
