您要查找的是不是：
- Another problem with HDSL is that it doesn't easily accommodate conventional voice traffic (POTS). HDSL的另一个问题是它不易适应常规的话音信息流（POTS，即普通的老式电话服务）。
- Each of these makes SVC an attractive alternative,especially when voice traffic is being added to an existing network. 这些优点使SVC成为一种很有吸引力的替代方式，尤其是话音通信加到已有的网络上时更是如此。
- Voice traffic,because of its sensitivity to delay,can provide a challenge for most network topologies. 由于话音通信对滞后敏感，所以它对大多数网络拓朴结构都是一种挑战。
- Although frame relay lessens the overhead of link retransmission, frame relay still requires that the voice traffic cross many physical paths. 虽然帧中继减少了链路重发传输的开销，但帧中继仍需要话音通信穿过多个物理通道。
- But if voice traffic must be routed over the network as part of the application, in universal messaging, for example, bandwidth is of paramount importance. 但是，如若声音话务是作为应用的一部分必须在网络上传输，例如在通用传信中，带宽具有头等的重要性。
- You can further mitigate the risk of simultaneous failures by using different vendors for data and voice traffic. 更进一步，你还可以通过数据和语音使用不同的运营商来转移风险。
- Voice traffic, because of its sensitivity to delay, can provide a challenge for most network topologies. 由于话音通信对滞后敏感，所以它对大多数网络拓朴结构都是一种挑战。
- One of the problems with using PVCs for voice traffic is the level of use often does not make this economical. 把PVC用于话音通信的问题之一就是，其使用水平经常达不到经济的程度。
- Each of these makes SVC an attractive alternative, especially when voice traffic is being added to an existing network. 这些优点使svc成为一种很有吸引力的替代方式，尤其是话音通信加到已有的网络上时更是如此。
- In many cases, voice traffic is sporadic and does not transmit between the same pair of endpoints, making PVC use ineffective and costly. 在很多情况下，话音通信是零散的，常常在同一对端点之间不进行传输，使得PVC的使用低效率、高成本。
- Although frame relay lessens the overhead of link retransmission,frame relay still requires that the voice traffic cross many physical paths. 虽然帧中继减少了链路重发传输的开销，但帧中继仍需要话音通信穿过多个物理通道。
- IP marketplace is currently focused on using Internet to pirate consumer voice traffic from traditional carriers by offering significantly lower prices. IP市场目前正利用因特网，以很低的得价格从传统的运营商那里挖走客户语音业务。
- In many cases,voice traffic is sporadic and does not transmit between the same pair of endpoints,making PVC use ineffective and costly. 在很多情况下，话音通信是零散的，常常在同一对端点之间不进行传输，使得PVC的使用低效率、高成本。
- What, no text messaging?No wonder mobiles now outnumber fixed phones, and that voice traffic is migrating from fixed to mobile networks. 难怪现在移动用户已经大大超过固定电话用户，并且通话业务也正在更多地从固定电话那里转移到移动网络。
- But if voice traffic must be routed over the network as part of the application,in universal messaging,for example,bandwidth is of paramount importance. 但是，如若声音话务是作为应用的一部分必须在网络上传输，例如在通用传信中，带宽具有头等的重要性。
- Besides bandwidth and latency, what other parameter is needed to give a good characterization of the quality of service offered by a network used for digitized voice traffic? 数字化的语音所经过的网络，除了对带宽和延迟有要求之外，还有什么参数影响它的服务质量?
- Telecommunication companies, computer hardware and software companies, and cable operators converge to compete for voice traffic, data traffic, and integration of networks. （电信业者、脑软硬体业者及有线电视业者等逐渐汇流至语音、料传输及网路整合业务上相互竞争。
- However,the concern is that voice traffic in frame environments built with permanent virtual circuits (PVC) will not be as cost-effective as frame nets built with switched virtual circuits (SVC). 但问题是，用永久虚拟电路（PVC）建立起来的帧环境中的话音通信的性能价格比不如用交换虚拟电路（SVC）建立起来的帧网络。
- In case the logic doesn't persuade you, Kelly piles on page after page of thought-provoking factoids. like this sci-fi sounding statistic: the current total volume of voice traffic on the global phone system is 1,000 times that of data. 如果这种逻辑不能使你信服，凯利还有一篇发人深思的说服文章。听起来像科幻小说的统计数据：当前全球电话系统的声音传送总量是其他信息量的一千倍。
- The rush hour traffic is murder. 交通高峰时间真是难以忍受之事
