Claim One:
1. A digital subscriber line ‘XDSL’ communication system for provisioning multi-tone modulated communications over a subscriber line, and the communication system comprising: a digital subscriber line access multiplexer (DSLAM) for distributing a near end crosstalk (NEXT) model of anticipated disturbance from neighboring disturber subscriber lines; and at least one modem having shared and discrete components forming a transmit path and a receive path and the at least one modem coupled to the DSLAM and responsive to the distributed NEXT model there from to adjust a dynamic range of an analog portion of the receive path to accommodate the anticipated disturbance modeled in the distributed NEXT model, whereby the adjusted range is large enough to substantially avoid clipping of a received signal and at the same time not so large as to result in significant excess dynamic range.
