Claim Text:
1. Method for providing an xDSL broadband transmission service between a central office and a customer premises equipment via a local loop, the method comprising: initiating a handshaking procedure between the central office and the customer premises equipment, determining an xDSL transmission standard with a specified transmission rate during the handshaking procedure for providing the xDSL broadband transmission service, utilizing a non-standard information field during the handshaking procedure to indicate a support of a non-standard mode between the central office and the customer premises equipment, initiating the non-standard mode, in case no synchronization is established between the central office and the customer premises equipment after the handshaking procedure, and reducing the transmission rate below a lowest transmission rate as defined in said xDSL standard and trying again to establish synchronization for said broadband transmission service, and in case synchronization is subsequently established, providing a non-standard transmission with reduced transmission rate for feeding diagnostic information about the local loop back to the central office.
