ABSTRACT:
A communication terminal connection system couples at least one source terminals to a destination terminal via a line, and comprises a channel switch connected to the terminals, at least one multiplexer coupled to the channel switch which is coupled between the terminals and the multiplexer, and a control part coupled to the channel switch for switching and controlling a connection of the channel switch. The control part includes a first detection part for detecting a request-to-use information which is received from a source terminal and requests use of the multiplexer, a second detection part for detecting an identification number to which the multiplexer is coupled via the line when the first detection part detects the request-to-use information, and a connection part for detecting a destination identification number of the destination terminal which is received from the source terminal following the request-to-use information and for controlling the channel switch to couple the source terminal to the multiplexer when the destination identification number matches the identification number detected by the second detection part, thereby coupling the source terminal to the destination terminal via the line.
