Network Performance Parameters for Dedicated Digital Services for Rates Up to and Including DS3 - Specifications
|Publication Date:||1 December 1999|
Scope and purpose
This standard applies to Dedicated Digital Services operating at nominal rates of 56/64 kbit/s, 1.544 Mbit/s and 44.736 Mbit/s with objectives based on the longest and most complex circuits. Dedicated Digital Services are characterized by established connections (i.e., no access or disengagement functions). The framework for this standard is provided by a companion standard: T1.503-1996 "Network Performance Parameters for Dedicated Digital Services - Definitions and Measurement Methods." The purpose of this standard is to provide values for the parameters defined in T1.503, to apportion these values among the network sections, and to specify procedures for their measurement. While the performance objectives are intended to apply to digital services in aggregate, it is recognized that such objectives may not be readily achieved by all of today's individual service connections.
T1.503 describes the rationale for the list of parameters used in this standard. For a given service, only a subset of these listed parameters will be referenced. This standard provides the specific parameter value limits needed for evaluating service quality and should be considered when designing network systems and equipment.
