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.

Dependent claims

An electrical splitter that splits upstream input to two or more downstream outputs, the splitter comprising:

a VDSL and PSTN input connector;
a diplexer downstream of the input that discriminates a VDSL signal input from a PSTN signal input and directs each signal to a respective output;
a VDSL output port;
a voltage blocker between the diplexer and the VDSL output, wherein the blocker inhibits DC and ring voltage from reaching the VDSL output;
a balun between the voltage blocker and the VDSL output to match input impedance to output impedance;
and
a PSTN output port downstream of the diplexer.
