Generic approaches to the design of network services circuits

This paper describes recent developments in modeling and analysis tools that are basic to a generic approach to the design of network services circuits for voiceband applications. Providing network services is a major part of the effort to support the tactical needs of telecommunications users. The design of network services circuits is the process of choosing configurations of transmission facilities and equipment for realizing circuits within appropriate performance specifications. Techniques for design have been developed under the general heading of “standard designs” and, until recently, have largely taken their structure from the capabilities of specific equipment.
