Network Synchronization and Alarm Remoting in The DatarouteT

This concise paper details the synchronization philosophy and instrumentalities adopted in The Dataroute [1], a TransCanada digital data network established in April 1973. The synchronization system discussed is a hierarchical master-slave system with a two-level hierarchy at locations physically distant from one another. A discussion of the alarm transmission in The Dataroute is also presented. Alarms in The Dataroute are displayed locally, and facilities are provided for their transmission to a regional center and a national center for real-time action as well as for management purposes, and report generation on demand.
