Abstract:
A method for exchange of control and signaling messages over a communications network having a common controller and at least one station, said common controller operable to transmit and receive both asynchronous transfer mode (ATM) messages and asynchronous variable length (VL) messages, said common controller synchronized with a station attempting to establish a data link, said method comprising the steps of:transmitting a signon request from said common controller to said at least one station;transmitting a signon response from said station attempting to establish a data link to said common controller, said signon response including identifying information pertaining to said station;performing a comparison of said identifying information to a database at said common controller;selecting an ATM transmission mode for said control and signaling messages between said common controller and said station if said comparison determines said station to be ATM manageable only; andselecting a VL transmission mode for said control and signaling messages between said common controller and said station if said comparison determines said station to be VL manageable only.
