1. A method for communication between at least a first unit and a second unit via a time division multiplexed communciation channel, comprising the steps of:

  • (a) transmitting an information signal from said first unit to at least said second unit in a first slot encoded at a first rate allocated to said first unit, said first slot having a first duration;

    (b) detecting by said first unit an information signal from said second unit in a second slot encoded at a second rate allocated to said second unit, said second rate being slower than said first rate, and said second slot having a second duration smaller than said first duration;

    (c) exchanging slot rate allocation for converting said first slot to said second duration to accommodate information encoded at said second rate re-allocated to said first unit in response to detecting activity of said second unit;

    (d) exchanging slot rate allocation for adapting said second slot to said first duration to accommodate information encoded at said first rate re-allocated to said second unit; and

    (e) operating, thereafter, to receive an information signal from said second unit in said second slot encoded at said first rate re-allocated to said second unit.
