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.

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.
