Abstract:

A combination VDSL Splitter/Balun, Low pass filter converts a copper pair containing VDSL signals and PSTN service to be compatible with home coaxial and twisted pair wiring. A device of the invention performs the following functions: accepts VDSL and PSTN service in on a single twisted pair; provides front end voltage spike protection and test resistance circuit; and splits off the PSTN service to a connector compatible with a twisted copper pair; prevents signals above the voice spectrum from entering back through the twisted copper pair by filtering it to an RF level below the VDSL signal. The VDSL signal continues through the device and through a voltage blocker preventing the line and ring voltage from continuing. The impedance of the twisted pair is matched, through a balun, to a coaxial output on the device.
