摘要
VoFR电话是基于帧中继的话音业务,其基本原理与VoIP类似,针对Passport 7480设备,探讨了经卫通链路VoFR电话断续问题的原因及解决对策,提出了VoFR语音测试的方法,进行了详细的数据测试以及比较分析,为VoFR业务的应用提供了理论依据,测试结果对VoIP有着很好的参考价值。
VoFR provides voice service on Frame Relay system,principle of which is similar with VoIP.Discusses the reason for the intermittence problem of VoFR which employs the Passport 7480 equipment,puts forward a solution for the problem and analyzes the testing data after several simulative experiments,at last brings forward the theoretical reference for the application of the VoFR system,which is also applicable for the VoIP system.
