1. An asynchronous transfer mode (ATM) based very-high-bit-rate digital subscriber line (VDSL) communication system for connecting a subscriber between different data service providers, the ATM based VDSL communication system comprising:

  • an ATM network connected to a plurality of data service providers;

    a host digital terminal connected to the ATM network by one of a plurality of ATM permanent virtual circuits, each of the ATM permanent virtual circuits associated with a corresponding one of the plurality of data service providers and being supported on a fiber optics link, wherein the plurality of ATM permanent virtual circuits connect the host digital terminal to the plurality of data service providers, the host digital terminal and the plurality of data service providers communicating data signals on the plurality of ATM permanent virtual circuits through the ATM network;

    an optical network unit connected to the host digital terminal by a fiber optics link;

    a customer provided equipment (CPE) data device connected through the optical network unit to the host digital terminal by a well known VDSL permanent virtual circuit, the well known VDSL permanent virtual circuit being supported on a fiber optics link between the host digital terminal and the optical network unit and a twisted pair drop between the optical network unit and the CPE data device, the CPE data device and the host digital terminal communicating data signals on the well known VDSL permanent virtual circuit; and

    a subscriber personal computer connected to the CPE data device for communicating data signals with the CPE data device, wherein the subscriber personal computer is operable to generate a channel change signal corresponding to a selected one of the plurality of data service providers;

    wherein the host digital terminal, in response to the channel change signal, connects the ATM permanent virtual circuit associated with the selected one of the data service providers with the well known VDSL permanent virtual circuit to establish a system PVC connecting the selected one of the data service providers with the subscriber personal computer, wherein the selected one of the data service providers and the subscriber personal computer communicate the data signals on the system PVC.
