In the RG business model, the RG system unit would initially be owned and managed by an access network provider. To permit owner access to the unit it is packaged in a weatherproof enclosure designed to be mounted at the point of entry to the residence, either outside or inside the building. The package consists of a rugged enclosure with lockable hatches permitting the owner, the subscriber, and potentially another service provider access to different sections of the unit. Internally, there are slots or receptacles for NIU adapters and CPI adapters. The unit also includes a high-performance, low-cost bus for communication among the adapters, a controlling microprocessor, and memory.
When mounted externally, the RG will be exposed to a very wide range of environmental factors. Some of this can be avoided (at a cost) by splitting the unit into two units (external and internal), with the internal unit accommodating the CPI adapters.
