Abstract
A digital loop system with a distributed architecture that provides telephone services with high reliability and quality and is cost-effective to install. The system is central office powered and uses a trunk unit interface to interface with a wide range of mechanical and electronic switches. The trunk unit interface connects to remote terminals via digital transmission lines. The remote terminals drive a large number of subscriber circuits through short subscriber loops. The distributed digital loop system employs sealed and environmentally hardened packaging for flexible outdoor installation. The electronic circuitry used by the remote terminals is divided into modules for flexible, incremental deployment of the system.
