Abstract
Various aspects of transmission quality in evolving telephone services are reviewed and summarized from the customer's point of view. The evolution of the public switched telephone network is described. Quality specification methodology is examined, covering transmission standards, the room environment, and quality measures. Transmission quality in mixed analog and digital operation and in advanced telephone services are considered. Future telephone services are discussed.Keywords
