An Operations System for Centralized Digital Transmission Network Maintenance

摘要

An operations system for centralized digital transmission network maintenance is described.This new system expands the scope of centralized maintenance from the traditional alarm monitoring and control functions to include sophisticated performance monitoring and fault location. For several years, the Telecommunications Alarm Surveillance and Control (TASC)system provided the traditional alarm and control functions for transmission networks and associated equipment. To meet the needs for digital transmission performance monitoring and fault location new feature sets for TASC along with the latest technology in minicomputer design have been used. Also, microprocessors are used in a distributed processor remote to provide data collection, data analysis and control capability. This new remote office unit is called an Advanced Telemetry Processor (ATP).We begin this paper by presenting an overview of the system and describing its architecture.We then describe the ATP: its overall functions, its interface to monitored transmission equipment, and its commnunications with the TASC central. We then conclude with a description of the TASC central. Particular emphasis is placed on the reports available to the user for performance monitoring and remote fault location.
