ABSTRACT:
A method of operating in a point-to-multipoint communication system with a base station and a plurality of remote stations, wherein the communication system enables transmission of data in a multicast mode with different Quadrature Amplitude Modulation (QAM) levels, carries switched point-to-point traffic without compromising the switched nature of the traffic in a broadcast environment, contains circuits for evaluating the Remote Station Identifier (RSI) and switch field tag portions of received Asynchronous Transfer Mode (ATM) cells using a series of registers to match the RSI and the unique remote address, and embeds multicast address data capable of identifying intended remote stations at varying QAM levels.
