<p>PURPOSE:To provide a private branch exchange not requiring any complicated operation from a terminal equipment which is simultaneously communicated with plural communication opposite parties. CONSTITUTION:A central control section 107 receives a call request packet from a packet terminal equipment 104 via an ISDN extension interface 109 and a packet handler module 106 to analyze an incoming address to plural communication parties coded in the dial request packet. Then the call request packet to each communication party is generated in response to the result of analysis and sent to the ISD network 101 via an ISDN external line interface 102 to attain simultaneous communication to the plural communication parties.</p> |
