Design Principles

Principles of Design and Operation

The RG Group has recommended several basic design principles to guide the development of the RG. They are:

Standards Principles

  • 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.
