1. A bandwidth allocation system for a twisted pair telephone wire local loop system, comprising: a subscriber digital filter system connected to the twisted pair telephone wire; a subscriber controller sending a control signal to the subscriber digital filter system; an office digital filter system connected to the twisted pair telephone wire; and an office controller sending a control signal to the office digital filter system, wherein the office controller receives a bandwidth allocation request and calculates a digital filter coefficients necessary to realize a digital filter to satisfy the bandwidth allocation request. 2. The bandwidth allocation system of claim 1, further including a splitter connected to the twisted pair telephone wire and having a low pass output connected to a POTS telephone and a high pass output connected to the subscriber digital filter system. 3. The bandwidth allocation system of claim 2, wherein the splitter has an analog low pass filter and an analog high pass filter. 4. The bandwidth allocation system of claim 1, further including a link quality testing system connected to the twisted pair telephone wire. 5. The bandwidth allocation system of claim 1, further including a subscriber transceiver coupled to the subscriber controller and the subscriber filter system. 6. A method of operating a bandwidth allocation system for a twisted pair telephone wire local loop system, comprising the steps of: (a) receiving a bandwidth allocation request at an office controller; (b) determining if a frequency band is available on a selected twisted pair telephone wire including, (b1) selecting an unused section of frequency; (b2) determining if the unused section of frequency has sufficient bandwidth; (b3) when the unused section of frequency has sufficient bandwidth, performing a link quality analysis; (b4) when the link quality analysis is greater than a predetermined minimum, defining the unused section of frequency as available; (c) when the frequency band is available, determining a filter scheme and a frequency translation scheme; (d) transmitting the filter scheme and the frequency translation scheme to a subscriber controller over a control channel; and (e) sending a bandwidth allocation available message by the office controller.
