Will etherSPLIT work with PBX and European telephone systems?
Yes. The splitter design passes the telephone line straight through with some filtering that does not affect the telephone system operation. This system has been tested with numerous line conditions and works will in all situations. Some PBX and Key phone systems require four wires. The splitters have been designed to allow for four wire telephone systems, but will require six wires (or three-pair) to allow for Ethernet AND four-wire phone systems to operate.
