of technological driving forces, notably fiber optics, digital switching, and customer controlled software, seen to be major influences in the evolving network, and relates their effects to network architecture, services, and vulnerabilities. In Chapter 6 the committee analyzes the impact of competition on the public switched network and relates this subject to NSEP issues. It includes a discussion of the providers of local and interexchange services, cellular mobile radio, customer-premises equipment, value-added networks, electronic databases, cable television, and some innovative services. Chapter 7 looks at a number of user needs that derive from what new technology may offer and would be affordable to a wide customer base. The committee discusses integrated voice, data, and image applications that will likely be available to residential, commercial, and institutional subscribers by the year 2000. It also points out how customer demand for more and better services can amplify network vulnerabilities that may result.
