Abstract: American National Standard X3.102 defines a set of 21 standard parameters that provide a uniform means of specifying the performance of data communication systems and services as seen by users. This report is basically an explanation and elaboration of that standard. The report first outlines the benefits of using the standard from the viewpoint of the end user, the communication provider, and the communication manager. The report then summarizes the standard's overall approach and content in informal, non-technical terms. Finally, the report examines the meaning and importance of each standard parameter in a series of tutorial parameter descriptions. Typical parameter values are presented and their design implications are discussed.
