SURVEY OF TINING/SYNCHRONIZATION OF OPERATING WIDERAND DIGITAL OPAMUNICATIONS NETWORKS

RONALD L. MITCHELL

Abstract:	In order to benefit from experience gained from the synchronization of operational wideband digital networks, a survey was made of three such systems: Data Transmission Company, Western Union Telegraph Company, and the Computer Communications Group of the Trans-Canada Telephone System. Additional information was obtained from AT&T relative to their Switched Digital Network, The focus of the survey was on deployment and operational experience from a practical (86 opposed to theoretical) viewpoint. The objective was to provide a report on the results of deployment-how the systems performed and wherein the performance differed from that predicted or intended in the design. It also attempted to determine how the various system designers would use the benefit of hindsight if they could design those same systems today. No conclusions or evaluations of the network performance are provided in the report. However, some of the differences in requirements between the commercial networks surveyed and those of strategic, survivable networks, such as the Defense Communications System, are noted.
