1. A method, comprising:
- sending one or more synchronization parameters from a receiver of a transceiver to a transmitter of another transceiver in a digital subscriber line (DSL) system;
adjusting transmission of synchronization data from the transmitter of the another transceiver to the receiver of the transceiver using the one or more synchronization parameters sent by the receiver of the transceiver; and
determining a need for synchronization data at the receiver of the transceiver by monitoring a quality of non-synchronization data received at the receiver of the transceiver from the transmitter of the another transceiver.

6. An apparatus, comprising:
a first transceiver and a second transceiver, wherein each of the first transceiver and the second transceiver transmits and receives data in a signal over a transmission medium, comprising; a receiver having a synchronization data extraction module; and a transmitter having a synchronization data insertion module; wherein the synchronization data extraction module of the receiver of the first transceiver determines a need for synchronization data, and requests the synchronization data by sending one or more synchronization parameters to the synchronization data insertion module of the transmitter of the second transceiver, and the synchronization data insertion module of the transmitter of the second transceiver transmits the synchronization data to the synchronization data extraction module of the receiver of the first transceiver in response to the request for the synchronization data from the synchronization data extraction module of the receiver of the first transceiver, wherein the synchronization data is used to adjust parameters of a data communication system. - View Dependent Claims (7, 8, 9, 10)

11. A computer accessible medium to store instructions that, when accessed by a computer, cause the computer to perform operations comprising:
-
sending one or more synchronization parameters from a receiver of a transceiver to a transmitter of another transceiver in a digital subscriber line (DSL) system; adjusting transmission of synchronization data from the transmitter of the another transceiver to the receiver of the transceiver using the one or more synchronization parameters sent by the receiver of the transceiver; and determining a need for synchronization data at the receiver of the transceiver by monitoring a quality of non-synchronization data received at the receiver of the transceiver from the transmitter of the another transceiver. - View Dependent Claims (12, 13, 14, 15, 16)
