Patent ID: 8275094

Claim:
A system for providing a wetting current in a broadband network comprising: an Asymmetric Digital Subscriber Line (ADSL)/Very high speed Digital Subscriber Line (VDSL2) broadband line card configured to communicate with one or more modems via a plurality of subscriber lines, wherein the modems are located in a user side of a broadband network; a line-capturing matrix configured to capture a first one of the subscriber lines and a second one of the subscriber lines; a wetting current circuit located in a network side of the broadband network and configured to provide a wetting current to the first subscriber line and the second subscriber line, wherein the first subscriber line and the second subscriber line only provide digital subscriber line (DSL) services; and a low-pass filtering circuit comprising of a first end and a second end, wherein the first end is connected to the line-capturing matrix and the second end is connected to the wetting current circuit, wherein the line capturing matrix is not directly connected to the wetting current circuit, and wherein the low-pass filtering circuit is configured to perform a low-pass filtering function on the wetting current and send the filtered wetting current over the first subscriber line.
