Over the transfer network , which serves as a common transfer platform for different telecommunications services , the growth of services , including voice , data , multimedia , leased lines and broadband service , and the development of the support networks such as the signaling network , the clock transfer network and the nm liaison network have made demand for transmission circuits 传送网作为各种电信业务的公共传送平台，包括话音、数据和多媒体、专线、宽带业务等在内的各类业务的增长，以及信令、时钟传送、网管联络等支撑网的增长，均对传输电路提出需求。
Chongqing expressway networking toll data communication network cotains 2 - ring and 8 - ray network structure based on expressway physical structure , setting up a trasmission trunk layer of sdh stm - 4 ( can be up - graded to stm - 16 ) , and channel protection business entry layer consisting of sdh onu / olt stm - 1 ( can be up - graded to stm - 4 ) . data exchange layer , through ip route exchange network above sdh network , forms 3 - level computer network structure of account settlement center - road section management company - toll station . to ensure obtaining original and reliable toll data from communication network , 2m circuitous chain is established between each toll station , accountsettlement center and road section management company , and also pstn dialing backup chain is set up between toll station and account settlement center . in order to maintain clock synchronization of the whole communication network , a proposal of sub - stage clock sychrononization signal network for differet network construction scale has been put forward in this design . in view of sensitivity and importance of toll data , this design particularly gives considerations of network safety and information safety for external and internel of network . therefore , communication safety , smoothness and reliability of networking toll system can be able to maintained in many ways 重庆高速公路联网收费数据通信网的结构是根据高速公路的物理结构构筑了2环8射的网状结构，建立了以sdhstm - 4 （可升级到stm - 16 ）的传输主干层，以sdhonu / oltstm - 1 （可升级到stm - 4 ）组成的通道保护业务接入层。数据的交换层是在sdh网之上的ip路由交换网，形成了结算中心-路段管理公司-收费站之间的3级计算机网络结构。为从通信网络上保证收费数据的原始性和可靠性，每个收费站和结算中心、路段管理公司之间建立了2m迂回链路，同时在收费站和结算中心之间建立了pstn的拨号备份链路。
Mitogen - activated protein ( map ) kinase signal transduction cascades are routes through which eukaryotic cells deliver extracellular messages to the cytosol and nucleus , and the increasing evidences showed that mapks are involved in aba - , sa - or h2o2 - signaling respectively . in addition , plant guard cells have been a well - developed model system for understanding how components interact within a signaling network in a single cell 本实验在表皮生物分析的基础上，主要利用显微注射技术、膜片钳技术和激光共聚焦显微技术，运用专一性蛋白激酶抑制剂处理，探索蛋白激酶对蚕豆( viciafabal . )气孔保卫细胞中aba和sa诱导的h _ 2o _ 2产生及其信号转导影响机理，结果如下： 1
Due to a & b double flats setting of stp ( signalling transfer point ) in different place , and working on mode of payload - sharing on signalling links ( couple links ) between sp ( signalling point ) and stp , the calling signalling sequence cannot be collected completely from single stp . thus it is difficult to synthesize signalling affair in the signalling supervision system . the first , this thesis illuminateds network architecture of no . 7 signalling network and no . 7 signalling centralized supervision system 由于七号信令网的信令转接点设备stp ( signallingtransferpoint )采用a 、 b双平面异地设置，下一级的信令点设备sp ( signallingpoint )至上一级的一对stp之间的信令路由采用负荷分担方式工作， sp至stp对的负荷分担链路形成耦合链路，导致在一个stp处无法采集到完整的呼叫信令序列，这样就给监测系统核心部分之一的信令事件合成带来了极大的难度。
Also both softswitch system structure and 3g communication system are based on ip - based packet - switch , signaling gateway as a important part in softswitch network , play a role of transfering ss7 signal message from ss7 signaling network to ip - based packet - switch network . firstly this paper introduce the development of telecom network and signaling transfer , and discussing the four layer structure of softswitch network ; based on this , educing the background of signaling gateway in next - generation - network ; also describes the ss7 signalling gateway structure , function and characteristic and protocol module ; then analyse the high availability implementation of signalling gateway 本文首先从电信网络和信令传输发展出发,介绍了下一代网络演进,以及下一代网络的核心-软交换网络结构的四个层次功能特点;从此引申出信令网关产生背景,简单介绍了信令网关结构以及其功能特点;再对信令网关中主要协议模块进行分析,并着重讨论了信令网关高可靠性的几种实现方式。
