Abstract:
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:connecting a test head to the xDSL port in the central office; applying a first voltage to the splitter to set a first relay therein for monitoring a voice path in the central office, wherein the spitter is located in the central office; and applying a second voltage to the splitter to set a second relay therein during the period when the first relay is set for isolating both the low pass filter and the high pass filter, thereby connecting the test head to the xDSL port to enable testing of the copper loop.
