The No. 1 ESS must compare favorably with existing switching systems in cost, reliability of operation, space requirements and ease of maintenance.
Companion articles in this issue 1 2 3 discuss the logical organization and diverse responsibilities of the central control (CC) as t h e primary information processing unit of the No.
The No. 1 electronic switching system has a much higher concentration of control than previous telephone systems.
Line and trunk translation data and operating programs for No. 1 ESS are stored in a large semipermanent memory. This memory is provided by modular units known as program stores.
The No.
The purpose of this paper is to give a detailed description of the architecture and circuit design of the No. 10A Remote Switching System (RSS) control complex.
A local Electronic Switching System (ESS) provides the call control for a 10A Remote Switching System (RSS).
The goal of this paper is to provide a general insight into the 10A RSS circuits and units making up the remote unit, with the exception of control which is covered in a separate article.
The physical design objectives of No.
