Traffic Service Position System No. 1: Remote Trunk Arrangement and Position Subsystem No. 2: Transmission and Signaling Considerations

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. BRUNE, R. J. PIERETH, and A. G. WEYGAND (Manuscript received December 11, 1978) Transmission and signaling implications are important for the successful introduction of the Remote Trunk Arrangement (RTA) and the Position Subsystem (PSS) NO. 2 features into the Traffic Service Position System (TSPS), since both features involve the possibility of substantial distances between the TSPS operators and the customers. Consequently, a new transmission plan including objectives for inserted connection loss (ICL), received noise, balance, and operator sidetone was established and some new transmission equipment was provided. The overall objectives, general and specific considerations, maintenance facilities, signaling implications, and new transmission equipment are described. Emphasis is placed on those aspects that are novel or newly introduced as the result of RTA and PSS No. 2.
