Abstract
A connection control equipment can connect a plurality of calls originating from a terminal to a private side terminal by identifying the calling terminal. Each of the user terminals sets a calling number and a calling sub-address or a user-to-user information for identifying the terminal in a call-setting message. A switching system of the connection control equipment receives the call-setting message and stores the calling number and the calling sub-address or the user-to-user information of the message, and connects the call to a private side terminal with which the same user terminal issuing the just received call is communicating. The switching system can connect calls from the same user terminal to the same private terminal, allowing for any user terminal to freely transmit a plurality of calls without considering how to access a host computer.
