Abstract: Dynamic Time Metered Delivery (DTMD) is a unique physical layer communication Method. DTMD uses enhanced time-based techniques to enable and control the flow of more data/Hertz through a variety of transmission media including existing and new copper phone lines, coaxial cable, fiber optic, powerline and wireless RF, Optical and Acoustic, to and from a comprehensive, multi-function customer data gateway. The system measures the transmission parameters as viewed from the “end of the line” and then sends these numerics back to the source which alters the shape of the basic signal structure such that when received at the far end, it will have maximum recognition attributes against interferers and noise. The present system and method add the adaptivity to the line conditions and set a maximum allowable data rate within the subscribed levels of performance.
