电话网上非话业务微机监测系统的研究

Study on the Microcomputer-Based NVTS Monitoring System for Telephone Networks

随着我国电话网内用户传真、电传和计算机通信等非话业务（Ｎｏｎ－ｖｏｉｃｅＴｒａｎｓｍｉｓｓｉｏｎＳｅｒｖｉｃｅｓ，ＮＶＴＳ）的飞速发展，如何控制未注册用户的入网电平和统计其ＮＶＴＳ话务流量，已成为电信网网路管理的迫切研究课题。本文论述一种基于微机的ＮＶＴＳ监测系统的设计与实现方法。该研究课题，将随机过程最佳检测，模式识别和数字信号处理等理论，应用于ＮＶＴＳ微机监测系统设计，提出了ＴＭＲ模式匹配分析算法和ＳＴＳ容错测试算法，有效地解决了强干扰电话信道上ＮＶＴＳ特征频谱模式的提取、分析及其可靠性问题，在现场运行中得到了准确的测试结果，并已在电信和铁路通信系统获得了实际应用。

Non-voice transmission services(NVTSs), such as telefax, telex and computer communications,have been a major repidly-growing communication services or telephone networks in the last decade. This paper deals with the design and implementation of a microcomputer-based NVTS monitoring system. In the research, theories of random processing detection, pattern recognition and digital signal processing(DSP) are applied to creat two algorithms tor spectrum pattern analysis and fuslt-tolerant detection. The system has shown high accuracy and reliability in site operation, and has been awarded a first prize of computer applications of Gansu Province.
