A uniform access layer will emerge , where the new generation multi - service comprehensive access system will replace the existing various access equipments with no uniform management standard 在网络的接入层，新一代的多业务综合接入系统将逐步取代现有的、各种各样的、缺乏统一管理标准的接入设备，形成统一的接入层。
The cdma system that would be used to transfer the multi - traffic and improve the performance with diversity is extensively studied for the multi - media and high speed data development in the paper 本文基于移动通信传输多媒体业务的需要，研究了多业务直扩系统，及用分集技术来提高系统性能。其主要内容和创新之处下： 1
A unified and large - capacity multi - service transport platform should support multiple protocols and transport mixed traffic , thus necessitating marked changes in the traditional sdh technology and equipment 采用统一的、大容量、多业务传送平台来支持多种协议和传送混合业务，这就要求传统的sdh技术和设备要有较大的变化。
In order to satisfy the needs , espacially under a variety of different services and the high data rate requirement , the search of highly efficient channel codes has definitely become highlighted in the b3g - system 为了达到新一代移动通信系统中多业务、高数据率传输的要求,高效信道编译码的研究就成为了学者们关注的对象。
Furthermore , people will benefit from the conveniences effected by internet through easy access to public telephones and public multimedia information terminalsmulti - service terminals found on the streets and in the malls 在街头、商场，人们可以方便地使用公用电话、公用多媒体信息终端多业务终端，感受网络给人们带来的巨大便利。
Along with the rapid development of ethernet , data service has become the main service of telecommunication , and the traditional sdh technology hasn ’ t been able to meet the needs of transmission 为了提高sdh网络大量承载数据业务的性能,多业务传送平台( mstp )技术应运而生。使用mstp技术可以在传统的sdh网络上高效承载多种数据业务。
The multi - service platform ons15454 is characterized by low system cost , compact form factor and support to capacity upgrading . in particular , it can provide circuit interfaces for various bitrates and service categories 多业务平台ons15454系统成本相对较低、体积较小，并能支持容量扩展，尤其是能够提供多种比特率和业务种类的电路接口。
With the multi - service sdh transport platform , especially the dxc - integrated multi - port sdh equipment , the question of service protection may be well resolved by making full use ring protection and meshed recovery capabilities 采用多业务sdh传送平台，尤其是集成了dxc的多端口sdh设备，可以充分利用环形保护和网状恢复能力来解决业务保护问题。
With the rapid growth of the network application , network systems are required to be faster , support multi - media and various protocols . these increase the complexity of the embedded system of modern network devices 随着网络应用的快速增长,用户对通信系统提出了快速、支持多业务、支持多协议的要求,致使现代通信设备中的嵌入式系统十分复杂。
