本文介绍的就是7号信令在西门子移动d 900交换机的应用。
This thesis is about the CCS7 applications at Siemens D900 switch mobile.
西门子移动d 900交换机是基于传统2g网络的交换机，符合7号信令规范，在我国有着非常广泛的应用。
Siemens Mobile Switch D900 is based on traditional 2g networks, accord to CCS7 standards, has a very wide range of applications in our country.
因特网的网络控制装置(可以是一个分开的路由器或交换机)，一般都用于七号信令网络和多个网络接入交换机之间。
An Internet network control device, which could be a separate router or switch, is typically used between the SS7 network and multiple net access switches.
此路由器或交换机不只是一个为网络接入交换机转换七号信号报文的网关。
The switch or router is more than just a gateway to translate SS7 messages for the network access switch.
然后介绍了西门子移动d 900交换机的硬件和7号信令如何在西门子移动d 900交换机上实现。
Then introduces the Siemens Mobile Switch D900 hardware and how CCS7 comply at the Siemens Mobile Switch D900 platform.
电话公司也对部署具有七号信令功能的接入交换机感兴趣，以提供新的服务和把因特网拨号通话从话音网络中解脱出来。
Telephone companies are interested in deploying SS7-capable access switches to offer new services and to off-load the Internet dial-up calls from the voice network.
文章详细介绍了七号信令方式的结构、信令点、以及如何在HARRIS交换机数据库中修改七号信令中的目的信令点编码（DPC）。
In order to solve this, problem a common channel signalling No. 7 system appears. The paper introduces how to modify DPC in HARRIS Switcher′s database in detail.
