Abstract:
A method of implementing a digital communications link connecting a digital controller section of an xDSL modem, located on a system motherboard of a computing system, to a separate analog section of the xDSL mode adapted to be substantially free of electronic noise from other electronic components on the motherboard which could significantly affect the overall operation of such xpSL modem, said method comprising the steps of:(a) providing a plurality of receive signal lines for communicating data from a remote xDSL modem; (b) providing a plurality of transmit signal lines for communicating data to the remote xDSL modem; (c) providing a bit clock signal line separate from said plurality of receive signal lines and said plurality of transmit signal lines for carrying a bit clock signal, which bit clock signal is generated by scaling a separate clock signal useable by the xDSL modem, such that said bit clock is variable to accommodate a plurality of different xDSL transmission protocols.
