Abstract
A remote XDSL transceiver unit (16) includes an XDSL transceiver (19) and a control block (18). The XDSL transceiver (19) is operable to establish and communicate across an XDSL physical layer. The control block (18) is coupled to the XDSL transceiver (19) and operates to transmit a request for service to a loop termination point. The control block (18) also operates to identify a signal received from the loop termination point (14) and respond based upon a current context of the remote XDSL transceiver unit (16). Further, the control block (18) operates to control power-up and training of the XDSL transceiver (19) such that the XDSL physical layer can be dynamically brought up and down. In one embodiment, the control block (18) operates to store profile information for an established XDSL physical layer to use for future re-establishing of the XDSL physical layer.
