Principles of Design and Operation
The RG Group has recommended several basic design principles to guide the development of the RG. They are:
The RG will be fully compliant with FCC Regulations;
The RG supports the relevant industry standards to offer the
proposed range of services; and
The primary function of the RG is to provide a standard network interface unit for communication signals, as opposed to information processing.
Reliability and Redundancy Principles
There should be the option for redundancy in the adapters providing higher availability, if desired;
The RG should follow and reinforce the telephone companies excellent reputation for availability (e.g., support uninterruptible power); and
The basic function of the RG is to deliver information from the access network via the NIU adapters to the CPI adapters and vice versa. This must be a high availability function and must not require continual intervention by the RG controlling microprocessor. This function should also survive the failure of the control microprocessor or any individual CPI adapter.
