在数据网络上运行语音所能提供的潜在节约是无可争议的,但是此前由于管理工具和标准的缺乏延缓了帧中继语音的广泛接受。市场研究公司Distributed Networking Associates公司认为:使用语音的帧中继用户比例不足10％。但是帧中继却拥有相当大的用户基础,而且通过在帧中继上实施语音可在(美)国内市场上获得良好的经济效益——帧中继语音一分钟的费用低于一美分,而交换语音的费用为每分钟7.5至15美分。另外FRAD(帧中继访问设备)厂商也认为,不远的将来,语音帧中继的使用很可能会增多,因为目前在他们的销售量中,具有语音功能的型号占据了相当高的比例。例如,在FRAD制造商Memotec公司
The potential savings provided by running voice over data networks are undisputed but have been slow to accept the widespread acceptance of Frame Relay voice due to the lack of management tools and standards. Distributed Networking Associates, a market research firm, said fewer than 10% of Frame Relay users are using voice. However, Frame Relay has a considerable user base and can be economically profitable in the U.S. market by implementing voice over Frame Relay - the cost of a frame-relay voice for less than a penny a minute, The cost of exchanging voice is 7.5 to 15 cents per minute. In addition FRAD (Frame Relay Access Device) manufacturers also believe that in the near future, the use of voice frame relay is likely to increase, because at present their sales, models with voice capabilities occupy a very high proportion. For example, at the FRAD manufacturer Memotec
