Abstract

An asynchronous transfer mode (ATM) based very-high-bit-rate digital subscriber line (VDSL) system for connecting a subscriber between different data service providers includes an ATM network connected to data service providers. A host digital terminal (HDT) is connected to the ATM network by an ATM permanent virtual circuit (PVC). Each of the ATM PVCs is associated with a corresponding one of the data service providers. The ATM PVCs connect the HDT to the data service providers. The HDT and the data service providers communicate data signals on the ATM PVCs through the ATM network. A customer provided equipment (CPE) data device is connected to the HDT by a VDSL PVC. The CPE device and the HDT communicate data signals on the VDSL PVC. A subscriber personal computer is connected to the CPE device for communicating data signals with the CPE device. The personal computer is operable to generate a channel signal corresponding to a selected one of the data service providers. The HDT, in response to the channel signal, connects the ATM PVC associated with the selected data service provider with the DSL PVC to establish a system PVC connecting the selected data service provider with the personal computer. The selected data service provider and the personal computer communicate the data signals on the system PVC.
