ABSTRACT:
Call information is transmitted between broadband switching modules (12) and a broadband services switch (10). Each broadband switching module (12) receives call information from outside the broadband services switch (10) and translates the information into asynchronous transfer mode (ATM) cells. Each broadband switching module (12) also generates a route setup cell and a route teardown cell in order to establish and release a connection path to another broadband switching module (12), respectively. The broadband switching module (12) sends the route setup cell, that includes a virtual circuit identifier identifying the connection path for the calling information ATM cells, along a dedicated VCI to an intermediary broadband switching module (12). The sending broadband switching module (12) then transmits the payload ATM cells containing the calling information immediately after transmitting the route setup cell and before receiving an indication that a connection path has been established. The payload ATM cells are transmitted along a payload VCI determined by the broadband switching module (12) which was placed within the route setup cell.
