Abstract

PURPOSE:To carry out an effective multi-address communication by controlling both the outgoing and incoming the connecting trunk circuits via the CPU, monitoring the connection state for both the originating and terminating subscribers and then sending out the command for the call connection plus the confirming information to both the outgoing and incoming trunks. CONSTITUTION:Originating subscriber TLX1 and terminating subscribers TLX2- TLX5 are connected together by multi-address unit 14 through converter 11 and via outgoing connecting trunk circuit 21 and incoming connecting trunk circuits 22-15 respectively. Here, unit 14 receives the selection signals which are transmitted to TLX2-TLX5 through circuits 22-25, and then transmits these signals via circuits 22-25. And the connection is controlled by CPU15 between circuit 21 and 22-25, thus monitoring the connection state between TLX1 and TLX2-TLX5. Thus, both the command for the call connection plus the confirmation information are transmitted to circuit 21 and 22-25. As a result, an effective multi-address communication becomes possible.
