A method, a system and equipment are described for expanding a home LAN (12) which comprises a home single telephone line (10) and supports a number of terminal devices (14, 16, 18, 19, 20) including a basic group of analog terminal devices (14, 16). The expanded home LAN (22, 56) can support at least one additional group of analog terminal devices (48, 66) without providing additional telephone line. The system comprises an RU module (26, 70) adapted to communicate with an access network (24, 54) via at least one telecommunication path (28, 72, 74) and utilizing a packetized data protocol, the RU module performing functions of MUX/DEMUX to transmit signals between the access network and the LAN (22, 56) in a form comprising packetized data. The system also comprises one or more NT modules (50, 68), operative to connect all analog terminal devices of the additional group(s) to the home single telephone line (36, 58), wherein each of the NT modules serves as an adapter between a packetized data protocol utilized by the RU module and a protocol of POTS interface used by the analog terminal devices connected to said NT module. The home LAN, being thus expanded, enables concurrent connection of any combination of its terminal devices to the access network.
