Interfaces and Adapters
The RG defined by this document is meant to provide a standardized approach to allow the interconnection of networks and devices. Specifically, it is intended to allow the interconnection of various existing (CATV, telephone, etc.) and future (FTTH, HFC, ATM, etc.) external networks to various in-home networks (telephone, coax, etc.) and consumer devices (telephones, TV, computers, etc.). This interconnection is achieved by providing Network Interface Unit (NIU) cards for each external network, which are bussed to Customer Premise Interface (CPI) cards for each in-house network. To be a successful device in the marketplace, the RG must add value to today's home configurations and to future configurations brought about by future proliferation of emerging broadband networks.
While the full list of interfaces (and the associated RG adapters) may be virtually endless, the following sections provide at least a starting point of minimal capability.
