Abstract: We describe a universal Ethernet telecommunications service (UETS) that combines the features of the telephone network, local area networks and the Internet in order to offer integrated broadband services by re-using the infrastructure of the telephone and electrical networks. User-network communication extends the Ethernet local network services to the infrastructure of the operator in the “Ethernet domain”, which is distinguished from the Internet “IP domain”. The access device offers packet telephone service, with power supply over the telephone pairs, which guarantees the emergency call through the exchange being provided with a battery and power control for energy saving. Terminals are also defined with a simple supervisor to support the applications used in the Internet, which communicate via the Ethernet domain with the LLC/MAC or TCP/IP protocols and via the IP domain with the TCP/IP protocols.
