Performance Parameters for Digital and Analog Service Modes

Martin Nesenbergs; William J. Hartman; Robert F. Linfield

Abstract: As with many technologies, the evolution of telecommunication systems is shaped by two driving forces – performance and cost. There is a real need to bridge the gap between 'performance' as perceived by the user in accomplishing a mission and 'performance' as perceived by the supplier to minimize costs of implementation and operations. The interrelationships between user–oriented performance parameters, engineering–oriented parameters, and cost parameters ultimately define the permissible tradeoffs. This report covers one phase of a multiple phase project to relate the performance needs of military network users with the performance provided by a particular telecommunications service and to seek least cost systems that would offer such service. In this first phase, the parameters describing the performance of two services, one analog and one digital, are defined and specific values assigned for the related service offerings. The interrelationship between the user–oriented parameters and values and the technical or engineering–oriented parameters and values was planned as the subject of a subsequent phase.
