Abstract:
1. An Ethernet extension device for extending Ethernet over twisted pair comprising: an Ethernet port for providing an Ethernet interface for receiving Ethernet signals from and transmitting Ethernet signals to an Ethernet cable connected thereto; a twisted pair port for providing an interface to tip and ring outside-plant conductors of a telephone network for receiving telephone network signals from and transmitting telephone network signals to a single twisted pair of the telephone network; a twisted pair transceiver for receiving telephone network signals from the twisted pair port; an Ethernet transceiver for receiving Ethernet signals from the Ethernet port, each of the twisted pair transceiver and the Ethernet transceiver being provided with communication interface for communicating with each other having a compatible signal converting device for processing, respectively, the telephone network signals and the Ethernet signals into a compatible signal format used by both of the twisted pair transceiver and the Ethernet transceiver and for transmitting their respective processed signals to the Ethernet port and the twisted pair port; and telephone network protection circuitry connected to the twisted pair port for providing protection against lightning surges and alternating current power faults required by the telephone network.
