| 1. | Voice communication system
话音通信系统 |
| 2. | Voice communications is highly sensitive to delays or irregularities in the transmission of voice signal components
话音通信是高度敏感的延误或违规传送声音信号元件 |
| 3. | 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。 |
| 4. | On the other hand the net based on copper - wire is widely used , potential and developmental
遍及我国城乡的铜线网是现今话音通信的物理基础，也是潜力巨大、尚待开发的数据通信用户接入资源。 |
| 5. | With the traditional switches based on circuit switching , voice signals are transmitted at the rate 64 kbits over networks
传统的交换机是基于电路交换技术的,话音通信以64kbits的速率在网络中传输。 |
| 6. | In voice transmission , to compress the signal amplitude into a narrow range be cause the amplifiers are linear over wide ranges
在话音通信中,因放大器的线性范围有限,把信号幅度压缩到一个较小范围的处理。 |
| 7. | 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。 |
| 8. | The goal is to generate additional traffic , but also to build user loyalty by providing customised content in addition to voice communications
目标是产生附加流量，同时在话音通信的基础上提供自定内容来建立用户忠诚度。 |
| 9. | 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。 |
| 10. | Unlike the second generation mobile communications system ( 2g ) , the third mobile communications system ( 3g ) is mainly serviced as satisfying people " s traffic demand at any moment and everywhere
不同于二代系统， 3g主要是为了解决人们随时随地话音通信的需求， 3g具有支持不同媒体业务的能力。 |
