The present invention is directed to a remotely actuated splitter bypass function (RASB) working in conjunction with a test head at the central office for testing and maintaining copper loops in the digital subscriber line environment. The RASB allows a competitive local exchange carrier to test and maintain the xDSL portion of the copper loop with minimal interference and disturbance to/from the plain old telephone system (POTS) service by bypassing the central office splitter. The splitter bypass operation includes the steps of selecting a copper loop pair for testing, actuating a first relay for monitor mode, actuating a second relay for bypass mode, testing the selected copper loop, and resetting the first and second relays back to normal mode. By applying positive and negative voltages from the tip and ring with respect to ground, various relays can be set (actuated) and reset to provide multiple modes of operations. In this manner, relays can be designed to respond in certain voltage levels and polarities.
A method for remotely bypassing a spitter having both a low pass filter and a high pass filter in a line sharing system for testing a copper loop, wherein the low pass filter is coupled to a voice port and the high pass filter is coupled to a xDSL port in a central office, the method comprising:
A method for testing a copper loop connected to a splitter in a central office having a low pass filter and a high pass filter, the low pass filter connected to a voice port and the high pass filter connected to a xDSL port, wherein the voice port and the xDSL port are located in the central office, the method comprising:
A splitter in a central office coupled to a copper loop, the splitter having a low pass filter connected to a voice port and a high pass filter connected to a xDSL port, wherein the voice port and the xDSL port are located in the central office, comprising:
A system for remotely bypassing a splitter having both a low pass filter and a high pass filter for testing a copper loop, the system comprising:
