Abstract
A communication server maintains profile information on twisted pair lines in a profile table. This profile information may be generated in a training session and then retrieved to train a modem or transceiver unit to communicate data over the associated twisted pair line using XDSL communication techniques.
Claims58
A communication server coupled to a plurality of twisted pair lines, the communication server comprising:
- a plurality of XDSL transceiver units;
- a line profile table having pre-stored profile information that reflects electrical parameters of each of a plurality of twisted pair lines for XDSL service;
- and
- a system controller operable to retrieve profile information for a twisted pair line from the line profile table, the system controller further operable to provide the retrieved profile information to an XDSL transceiver unit coupled to the twisted pair line.
A communication device, comprising:
- an XDSL transceiver unit operable to couple to a twisted pair line;
- a plurality of registers associated with the XDSL transceiver unit;
- and
- a microcontroller coupled to the XDSL transceiver unit and the registers, the microcontroller operable to receive pre-stored profile information that reflects electrical parameters of the twisted pair line for XDSL service from an external device, the microcontroller further operable to store the profile information in the registers in preparation for XDSL communication using the twisted pair line.
A method for communicating using a plurality of XDSL transceiver units and a plurality of twisted pair lines, the method comprising:
- storing profile information that reflects electrical parameters of each of a plurality of twisted pair lines for XDSL service;
- coupling an XDSL transceiver unit to a twisted pair line;
- retrieving the previously stored profile information for the twisted pair line;
- and
- providing the retrieved profile information to the XDSL transceiver unit coupled to the twisted pair line in preparation for XDSL communication.
A method for communicating performed on an XDSL transceiver unit, comprising:
- coupling an XDSL transceiver unit to a twisted pair line;
- receiving pre-stored profile information that reflects electrical parameters of the twisted pair line for XDSL service from an external device;
- and
- storing the received profile information in the XDSL transceiver unit in preparation for XDSL communication using the twisted pair line.
