Brian suggests that if the high-quality lower frequencies (0-4KHz) normally reserved for voice were used exclusively for data, ‘broadband’ data connections could be made over long distances into rural areas. Voice communications would the be carried over the digital connection using Voice over IP.

With this kind of data connection providing about 115.9kbits/s upstream and 231.3kbits/s downstream, it would be possible to utilize the 20.8kbits/s G.723.1 codec for digital voice communication.
