Error performance in evolving digital networks including ISDNs

摘要

Some recent developments on error performance design methodology and the status of international standardization activities on network performance objectives are discussed. The effects of errors in various services and common error performance parameters are outlined, and a fundamental strategy for ISDN (integrated-services digital network) performance design methodology is presented. Error performance under real operating conditions and in-service monitoring of error performance are described. The status of CCITT Recommendations G.821 and M.550 is examined, and the areas that must be addressed by future studies are identified.
