Abstract: The present invention relates to a system for directly connecting two PC modems over dry copper, for the purpose of accessing an outside provider of computational services, substantially as though the connection were provided by the telephone network services. In preferred embodiments, both modems follow the V.90 specification, and are connected through an analog front end which emulates some components of the digital telephone network services. In another preferred embodiment, the present invention enables a group of private users in a contained community of one or more adjacent buildings, each with a PC modem, to share a higher speed digital line, such as an ISDN for example, for the purpose of providing a more economical access to a computational service.
