ABSTRACT:
A method, and apparatus in an ISDN system form a setup message at a source ISDN terminal where the setup message includes a resource coordination message containing the communication attributes of the source terminal. The ISDN source terminal sends the setup message to an ISDN switch, where the ISDN switch implements a central resource coordination mechanism that extracts the source terminal attribute information. The ISDN switch sends an inquiry message over a D channel to a destination terminal so as to ascertain the communication attributes of the destination terminal, which are reported to the ISDN switch in a reply message. In light of the communication attributes of the source terminal and destination terminal, the ISDN switch and central resource coordination mechanism therein, compares and allocates ISDN communication resources and identifies common attributes. Based on the common attributes, the ISDN allocates a B channel, or at least a portion of a B channel, so that a most efficient, and highest capacity communication link may be established between the source terminal and destination terminal.
