Abstract:
An apparatus in an integrated services digital network computer-based system that identifies common communication attributes of a destination terminal and a source terminal, prior to establishing an asynchronous communication link between the source terminal and destination terminal, said apparatus comprising:the source terminal, having, a source processor, a source memory accessible to the source processor, said source memory configured to hold a source terminal program that when executed by the source processor forms an ISDN setup message having a coordination resource message contained therein, said source memory being configured to hold source terminal communication attributes for inclusion in said coordination resource message, and a source terminal interface configured to be coupled to an ISDN switch using an asynchronous protocol and adapted to send said coordination resource message to said ISDN switch, wherein said coordination resource message provides said ISDN switch with said source terminal communication attributes so that said ISDN switch is informed of the source terminal communication attributes for comparison with the destination terminal communication attributes prior to establishing said communications link.
