1. A method for transmitting information within a communication system comprising an application node, a base transceiver node and a field transceiver node;

  • said method comprising the steps of;

    transmitting information between said field transceiver node and said base transceiver node at a variable data rate via a first fixed bandwidth information channel, wherein said variable data rate is a function of the transmission quality afforded by said first fixed bandwidth information channel, and wherein, prior to the transmission of said information between said field transceiver node and said base transceiver node, the effective rate of said variable data rate information is elevated via bitstuffing or reduced via buffering to match the transmission rate supported by said first fixed bandwidth information channel;

    transmitting, from said base transceiver node to said application node, a signal indicative of the present variable data rate at which information is being transmitted between said field transceiver node and said base transceiver node via said first fixed bandwidth information channel; and

    varying the data rate at which information is transmitted between said application node and said base transceiver node via a second fixed bandwidth information channel as a function of said received signal indicative of said variable data rate of transmission between said field transceiver node and said base transceiver node, wherein, prior to the transmission of said information between said application node and said base transceiver node, the effective rate of said variable data rate information is elevated via bitstuffing or reduced via buffering to match the transmission rate supported by said second fixed bandwidth information channel.
