Vol. 58, No. 6, July-August 1979 Printed in U.S.A. Traffic Service Position System No. 1: Remote Trunk Arrangement and Position Subsystem No. 2: Transmission and Signaling Considerations By W. L.
Early in the RTA planning process, it was recognized that controlling trunks, networks, and test circuits remotely was a task similar to controlling operator positions, voice path circuits, and tes
The Traffic Service Position System No. 1 ( T S P S ) helps the operator more efficiently handle toll calls such as collect, credit card, charge to third number, and coin toll calls.
This paper describes the tools of TSPS software generation and testing in the following environments: (i) The facilities provided via a general-purpose IBM processor for the production of testable
The new functions needed in TSPS for Automated Coin Toll Service are provided by the newly designed Station Signaling and Announcement Subsystem (SSAS).
A significant part of the effort required for any switching system development involves determining whether the system performs properly. The ultimate judge of system performance is the user.
One of the development objectives of the Traffic Service Position System No. IB (TSPS No. IB) was to improve the call-handling capacity of the TSPS No.
The 3B20 Duplex Processor (3B20D) was developed as a generalpurpose processor with a set of common system peripherals to support a wide range of applications and an instruction set optimized for a
The first Traffic Service Position System No. IB (TSPS No. IB) was placed in service in Fresno, California, on November 20,1981.
The planning of Traffic Service Position System (TSPS) installations and growth is rather different from that usually encountered in engineering central office equipment.1 One of the reasons for th
