  • Patent number: 6714535
    Abstract: A method and system for providing telephony services over a data network is disclosed. According to one embodiment, a service provider enters a service plan with a user. The service plan ensures the user a fixed cost for a substantial long period regardless how long the telephony service is used by the user. Further the service plan requires no purchase of any equipment nor regulates the use of the services in terms of time or distance. The service plan is incorporated in a gatekeeper that is coupled to the data network and administrates all connections over the data network.

  • Patent number: 6393111
    Abstract: A network interface for home networking implemented upon an existing 4-wire (two-pair) phone line system is disclosed. The interface comprises two transmitters, two line isolators and a receiver. The two transmitters transmit data simultaneously to both of the pairs of wires in the phone line system so that all devices coupled to the phone line system, regardless which pair of wires being coupled onto, can receive the data. Because all the pairs carry the data, there is therefore needed one on receiver in the interface to receive the data transmitting over the phone line system. The disclosed interface provides a solution to the home networking which no longer requires the knowledge of the underlying wiring structure in the phone line system.

  • Patent number: 6012951
    Abstract: An improved phone plug comprises a housing having a rear-receiving end and a plugging end, a number of inductors and conductors. The plug-receiving socket is formed in the rear-receiving end and adapted to receive a modular phone plug; the plugging end being so formed that the plugging end can be plugged into a regular phone jack coupled to the phone line system including the data network. The conductors are mounted in the housing and have first ends and second ends; the first ends projecting into the plug-receiving socket for engaging a contact of the modular phone plug when the modular phone plug is inserted into the plug-receiving socket; the second ends coupled respectively to the plugging end through the inductors.
