This paper describes the software development process used in generating Electronic Tandem Service (ETS) features for the DIMENSION 2000 PBX. ETS provides the corporate customer with a uniform numbering plan for all locations (unique 7 digit number for each station on the network), network cost control features (routing, queuing, and authorization privileges), and methods for admin istering and controlling network performance. The paper is organized into four sections. Section 2 describes the DIMENSION 2000 PBX design structure and software development environment. Section 3 covers the methods used for requirements, design, testing, personnel organization, and tracking. Lastly, Section 4 discusses the results in terms of trouble rates and productivity figures.
