Traffic Service Position System No. 1B: Switching Control Center System interface

Over the years, the centralization of the maintenance and operation of Stored Program Control Systems (SPCS) has proved to be an economically attractive and effective methodology. At the core of the centralized maintenance plan is the Switching Control Center (SCC), which has responsibility for the surveillance and control of a number of SPCS. This center is supported by the Switching Control Center System (SCCS), which is a minicomputer-based system that provides automation of, or mechanized support for, the functions of the SCC. Since SCCS support for the Traffic Service Position System No. 1 (TSPS No. 1) was already available, these capabilities needed to be carried forward to support the operation and maintenance of TSPS No. 1B. In addition, the use of the new 3B20D Processor with a new craftperson interface allowed for a number of improvements and extensions. The SCCS interface to TSPS No. 1B has made use of new technology and techniques by incorporating microprocessors, video terminal interfaces, and BX.25 protocol in the design. The result is a flexible interface with software-driven craft displays.
