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。
With the rapid development of Non-voice Transmission Services (NVTS) such as fax, telex and computer communication in China’s telephone network, how to control the network access level and statistics of NVTS traffic flow of unregistered users has become a hot issue in the telecommunications network Road management urgent research topic. This article discusses a computer-based NVTS monitoring system design and implementation. The research topic, the best detection of stochastic processes, pattern recognition and digital signal processing theory used in NVTS microcomputer monitoring system design, TMR pattern matching analysis algorithm and fault tolerant test algorithm STS, effectively solve the strong interference on the telephone channel The extraction, analysis and reliability of NVTS feature spectral patterns have obtained accurate test results in field operation and have gained practical application in telecom and railway communication systems.
