ABSTRACT: Reliability and System Architecture Testing (RSAT) is a method for assessing the reliability characteristics of a switching system. These characteristics include fault tolerance, fault detection, and system recovery, and the effects of these actions on call processing, billing, etc.

This Special Report (SR) describes RSAT as performed for circuit switching systems by Telcordia. The document also provides an overview of the types of RSAT tests, the necessary pretest activities, and the equipment and test conditions typically needed to perform such tests.
