1. A system providing a framework for the negotiation of a dual-channel communication protocol between modems connected by a communications link comprising:

  • an initializer for disabling an existing communications protocol;

    a detector for determining conditions allowing for the negotiation of the dual-channel communication protocol;

    a channel builder for establishing the dual-channel communications protocol comprising;

    a data channel of the dual-channel communications protocol enabled for sending and receiving data; and

    a command channel of the dual-channel communications protocol enabled for channel command and status information; and

    a negotiator for selecting a supplemental algorithm for running on the data channel from a plurality of algorithms;

    wherein the initializer, the detector, the channel builder and the negotiator, in total, complete their respective execution in a configureable and finite amount of time and wherein the conditions include error correction being enabled and data compression being disabled between the modems.
