Communication infrastructure and method for exchanging plurality of bidirectional signals with terminals of a building

摘要

Circuits and method for connecting a communication terminal to at least one end of a twist pair of a building infrastructure and to a complimentary circuit terminating the other end of the twist pair for propagating distinctly modulated higher carrier frequency and lower carrier frequency for propagating simultaneously two modulated information signals comprising higher speed data and lower speed data via at least one twist pair, the higher speed data is used for upgrading and loading data into a memory of the communication terminal and the lower speed data controls and directs the higher speed data through I/O ports of each of the CPUs included in the two circuits terminating the twist pair, the communication terminal uses the stored data to select items of service and merchandise for shopping in a closed circuit e-commerce by propagating a completed order to a server of the building.
