Its catchment area covers 15 square kilometers , and it flows northward from lin tong mei through hang tau tai po and kwu tung to join the river indus at ho sheung heung 双鱼河的集水区有15平方公里，源头位于莲塘尾，向北流经坑头大布和古洞，于河上乡处汇接梧桐河。
The stm - 1 interface will first be led in through tandem points where large volume of traffic is assembled , then gradually applied to large nodes that require over 30 2mbits trunks 交换机的stm - 1接口首先会在话务量集中的汇接节点引入，然后逐步在需要30多条2mbits中继电路以上的大型节点推广应用。
Beijing mobile will also introduce in 2002 stm - 1 interfaces in mscs and gmscs for the first time , and put into operation 130 155 mbits paths , equivalent to 8000 e1 paths 我们的同行北京移动也将在2002年的发展中，在移动交换机msc和汇接局gmsc中首次在国内引入stm 1接口，并将开通130条155mbits通路，相当于8000条e1通路。
If other end offices have rapid increase in the suburban traffic volume , this suggestion can be used with some adjustment , and the new added switching system also be transferred into city network based on incoming and outgoing calls 在以后的运行中，如果其他端局市郊话务量增长较快时，也照此方案进行调整，并且以后新开的交换系统也需按来去话汇接方式入网。
The development of information service industry is very fast , so the city was designated as a city on trail of information popularity in the country , one of the three big junction stations of long distance call of guangdong , one of the four big cores of the internet 江门市信息服务业发展迅速，被国家定为全国信息化试点城市，是广东省三大长途汇接中心之一，互联网四大核心节点之一，视讯宽带信息网络中心成为省的三大枢纽站之一。
To accommodate information data flow ( voice , visual and graphic ) from various communication sub - systems , to choose appropriate means of building sdh networks and sdh transmission modules constitute the keys to the application of communication technology in city ' s trail transportation 城市轨道交通通信技术的应用，应围绕sdh传输技术这一主线，汇接容纳各通信子系统的信息数据流(话音、视频、图像) ，选择合理的sdh传输组网方式和sdh传输形式。
Later it analyses the network applications and function requirements of scst as a c4 and service - providing platform , designs the total software architecture of scst , and introduces the function of different sub modules . then it gives the design scheme of the multi - protocol access module and media - controlling module . after that , the dissertation shows the 文章接着分析了软交换中继呼叫服务器作为汇接平台及业务提供平台的组网应用及功能需求,在此基础上提出了软交换中继呼叫服务器的总体软件构架,并介绍了各软件模块的功能。
Owning to the network structure of the transactions from the outgoing calls to incoming calls , we therefore suggested that to transfer these 5 bureaus to the city network , i . e . 6975 and 6977 bureau be merged into t21 , t23 , t24 , t12 and t6 , 8049 bureau be merged into t42 , t43 , t44 , t32 and t5 , 8959 and 6957 bureau be merged into t42 , t43 , t44 , t32 and t5 . these direct trunking lines are used only for the tandem of the suburban traffic of this end office and its inter - network calls , while the long distance calls are dealt with by the auxiliary tandem office 由于整个北京电话网的网络结构要由去话汇接方式向来去话汇接方式过渡，所以我们建议该5个局以来去话方式入大网，即6975 、 6977局入t21 、 t23 、 t24 、 t12 、 t6 ， 8049局入t42 、 t43 、 t44 、 t32 、 t5 ， 8959 、 6957局入t42 、 t43 、 t44 、 t32 、 t5 ，这些直达中继只汇接本端局的市郊话务量和该端局的网间呼叫，长途呼叫仍由原辅助汇接局汇接。
According to the statistical analysis , it is suggested that we should add 5 direct trunk lines from the end offices ( 6975 , 6977 , 8049 , 8959 and 6957 ) to the urban tandem offices to relay the voice traffic . this will help to reduce the pressure of the auxiliary tandem offices 根据统计和分析，我们认为应该增开6975 、 6977 、 8049 、 8959 、 6957等5个端局到市内汇接局的直达中继，用以汇接市郊话务量，以缓解辅助汇接局的压力，特别能够缓解辅助汇接局中继模块紧张的状况。
The whole project focuses on how to design and realize the scst ( softswitch call server trunk ) . the scst can provide the class 4 switch function for various access networks . also , as a service - providing platform , it works with service control point or application server to provide network users with the value - added services 本课题研究的就是如何设计和实现软交换中继呼叫服务器,使其能够汇接多种接入网络,并能作为统一的业务提供平台,结合业务控制节点或者应用服务器为融合网络用户提供智能业务及新型增值业务。
