home network). In most circumstances (ISDN, T1, and other low- and medium-speed data services) this requirement could be met with the normal telephony prewire in many homes. This would again require a separate card, believed to be relatively simple.

A further expansion of this concept would be to add the capability of home stereo-type functions. This will require some very complex and expensive modules, and the currently available alternatives are very expensive and inflexible. It would be relatively easy to extend the concepts wherein to include pre-amp type functions in a card that would have direct access to all of the connected networks, and that could drive amps and speakers. This type of functionality would provide for advanced multi-media delivery services to a number of home devices.

The above description may at first reading, suggest that the RG is a complicating device rather than a simplifying one. But, in reality, the RG will hide the complexity for the consumer of the multiple sources to multiple (and incompatible) receivers. Herein lies the need for a common interface. The RG also greatly simplifies the design of network and CPE devices by the standardization of interfaces, while still leaving the opportunity for functional innovation for competitive differentiation. The development of new services will no longer require that network and CPE developments take place at the same pace. New and innovative consumer services will be achieved by the design of new CPE, and where necessary, by the design of new RG interface modules. The addition of MPEG, ADSL, ATM, and other technology standards will be accommodated by simply adding a network card of the appropriate type. With the approach outlined, the full capability of those technology standards will be available to a wide variety of
