Method and devices for providing wetting current

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 line testing device that is connected to the line-capturing matrix and, wherein the line test device is configured to test the first subscriber line and the second subscriber line, wherein the wetting current circuit is not located between the ADSL/VDSL2 broadband line card and the subscriber line, and wherein the wetting current circuit and the line test device share a test bus.

• wherein the first subscriber line and the second subscriber line only provide digital subscriber line (DSL) services;
• and
• a splitter card comprising:
• the line-grabbing matrix;
• the wetting current circuit;
• a splitter comprising a first end and a second end, wherein the first end is connected to the subscriber line, and wherein the second end is connected to a plain old telephone service (POTS);
• and
• a low-pass filtering circuit comprising a first end and a second end, wherein the first end is connected to the line-capturing matrix, and wherein the second end is connected to the wetting current circuit.

A network device configured to:

• capture a first subscriber line that provides only digital subscriber line (DSL) services;
• provide a wetting current over the first subscriber line;
• capture a second subscriber line that provides only DSL services;
• provide the wetting current over the second subscriber line;
• and
• perform a low pass filtering function on the wetting current and send the filtered wetting current over the first subscriber line and the second subscriber line,
• wherein the network device is located on the network side of the broadband network.

A splitter card in a broadband network comprising:

• a line-capturing matrix configured to capture a first one of a plurality of subscriber lines and a second one of the plurality of subscriber lines, wherein the subscriber lines are used by an Asymmetric Digital Subscriber Line (ADSL)/Very high speed Digital Subscriber Line (VDSL2) broadband line card to communicate with one or more modems located in a user side of the broadband network;
• a wetting current circuit configured to provide a wetting current to the first subscriber line and the second subscriber line;
• and
• a low-pass filtering circuit configured to perform a low-pass filtering function on the wetting current and subsequently, send the wetting current over the first subscriber line and the second subscriber line,
• wherein the first subscriber line and the second provider line only provides digital subscriber line (DSL) services, and
• wherein the splitter card is located in a network side of the broadband network.

A method for providing a wetting current in a broadband network, the method comprising:

• capturing a first one of a plurality of subscriber lines used by an Asymmetric Digital Subscriber Line (ADSL)/Very high speed Digital Subscriber Line (VDSL2) broadband line card to communicate with one or more modems located in a user side of the broadband network;
• sending, by a wetting current circuit, the wetting current over the first subscriber line;
• capturing a second one of the plurality of subscriber lines;
• and
• sending, by a wetting current circuit, the wetting current over the second subscriber line,
• wherein the first subscriber line and the second subscriber line only provides digital subscriber line (DSL) services,
• wherein the wetting current circuit is located in a network side of the broadband network, and
• wherein a low-pass filtering function is performed on the wetting current before sending the wetting current over the first subscriber line and the second subscriber line.
