摘要

基于PON（无源光网络）技术的光纤宽带网络正在快速发展

传统PSTN（公共交换电话网络）语音业务正逐步被基于PON的多业务统一接入替代

如何快速高效地完成PON承载的语音业务故障诊断是服务提供商面临的难题。文章介绍了基于PON的语音业务组网特点和实现流程

分析了语音业务故障诊断的需求

设计了一种利用ONU（光网络单元）模拟语音呼叫信令的技术方案。实际测试表明

该方案能够模拟用户完成语音呼入呼出操作

自动分析语音呼叫故障原因

简化了语音业务故障处理流程

提升了服务效率。

Abstract

Passive Optical Network（PON）technology-based fiber-optic broadband networks are growing rapidly and the traditional PSTN voice services are gradually being replaced by PON-based multi-service bearer.So

fast and efficient implementation of fault diagnosis for PON-based voice service is a problem to service providers.This paper introduces the features and implementation process of the PON-based voice service networking

analyzes the needs for troubleshooting and designs a technical scheme for simulating voice call signaling by using ONU.Test results indicate that this scheme can simulate the operation of user calls

automatically analyze the causes for voice call malfunction

simplify the voice service troubleshooting processes and improve service efficiency.
