A new subsystem, Station Signaling and Announcement Subsystem (ssas), was added to tsps to provide automated coin toll service. Presented here are descriptions of how this new subsystem generates announcements from digitally stored speech samples, how it responds to coin deposit signals from coin stations, how the announcement circuits and coin tone detection circuits are automatically tested, and how the subsystem is physically packaged.

The Traffic Service Position System No. 1B (TSPS No. 1B) was developed by replacing the Stored Program Control No. 1A (SPC 1A) with the SPC 1B, consisting of a 3B20 Duplex Processor (3B20D) and a Peripheral System Interface (PSI). The PSI was designed to interface the 3B20D Processor technology with the existing TSPS peripheral system. This article describes the differences in technologies between the SPC 1A and SPC 1B, the hardware design required to overcome these differences, and the fault recovery and diagnostic software development required to integrate the new hardware into the maintenance structure of the TSPS No. 1B.

Traffic Service Position System (TSPS) No. 1 is designed to make toll customer service and operator call handling more efficient. This equipment is designed to give improved and dependable service. Connectorization is added to permit more efficient shop testing, installation simplification and a ready means to effect quick growth in a working environment. The switchroom equipment and operator facilities are specially designed for pleasing proportion and harmonious color schemes.
