Abstract: A method of using a controlled interface for managing data communicated between a first device and a second device. The method includes storing a first low-level protocol address and a second low-level protocol address in the controlled interface, receiving from the first device a first signal at a first part of the controlled interface, the first signal having first high-level addressing data, stripping the high-level addressing data to yield a first payload, associating the low-level protocol address with the first payload, transmitting the low-level addressed payload to a second part of the controlled interface, stripping, at the second part of the controlled interface, the low-level protocol address associated with the low-level addressed payload, associating a second high-level addressing data to the payload and transmitting the high-level addressed payload from the second part of the controlled interface to the second device.

Abstract: A controlled interface includes a first component communicating with a first device via a network connection, a first media converter having a first media converter disabled transmit port and a first media converter receive port, the first media converter connected via a connection to the first component, a second media converter having a second media converter transmit port and a second media converter receive port, the second media converter connected via a third network connection to the first component. A second component communicates with the second device via a connection. A third media converter has a third media converter transmit port and a third media converter receive port. The third media converter communicates with the second component via a connection. A fourth media converter has a fourth media converter disabled transmit port and a fourth media converter receive port.
