在开发 VoIP 系统时，主要考虑的一个方面就是连接到模拟电话的接口。设计人员必须了解 PSTN 中存在的电话接口要求，因为它们必须在 VoIP 系统中得到支持。本文将重点介绍连接到标准 POTS 电话的两种最常用接口：Foreign eXchange Subscriber (FXS) 与 Foreign eXchange Office (FXO)。重点说明了设计人员在为 VoIP 小区网关的模拟电话接口提供支持时可能面临的某些挑战。-In the development of VoIP system, one aspect of the main considerations is connected to the analog telephone interface. Designers must understand the existing PSTN telephone interface requirements, because they are in the VoIP system must be supported. This article will focus on the standard POTS telephone connected to the two most commonly used interface: Foreign eXchange Subscriber (FXS) and Foreign eXchange Office (FXO). Focusing on the design staff in the Residential Gateway for VoIP analog telephone interface may provide support to some of the challenges faced.

这是一个视频传输的c＋＋源程序，通过服务器转发的程序-This is a video transmission of the c source code, transmitted through the server process

MyICQ是一套完全公开源代码的即时通讯软件，包括服务器端和客户端，可以用于互联网或局域网中。可以运行在Windows或Linux(KDE/Qt)操作系统上，这是Windows的客户端。MyICQ完全支持服务器之间的松散连接，这意味着任何人都可以在Internet上架设自己的服务器。群组功能使您能够享受到聊天室和网络游戏所带来的快乐。 --------------- 基本功能特点 --------------- 采用MySQL数据库 日志文件 配置文件 NT服务 数据库查询部分采用多线程 系统管理员(MyICQ# = 10000)可以发送广播消息给所有在线和离线的用户 客户端与服务器的通讯采用DES的加密算法 支持服务器松散连接 群组功能，包括聊天室和游戏大厅-MyICQ is a completely open-source instant messaging software, including server and client, can be used for the Internet or LAN. Can run on Windows or Linux (KDE/Qt) operating systems, This is the Windows client. MyICQ fully support server link between the loose, This means that anyone can set up in their own Internet server. Functional groups so that you can enjoy chat rooms and online games from happiness.--------------- Basic features using My--------------- SQL database log file configuration file NT server database query part of a multi-threaded system administrator (MyIC Q# = 10000) can be sent to all

应用背景这是利用一些数学运算对信号进行相位计算的算法。关键技术CORDIC算法给出正确的相位值，采用一些计算。 ；

此软件可以很顺利的实现网络对话，这样对网络编程的初学者很有帮助的-software can smooth network dialogue, the network programming beginners helpful!

该程序可以用于两个人在LAN/Intranet(或者Internet)上进行视频会议。现在有许多视频会议程序，每个都有各自的性能提升技术。主要的问题是视频会议视频帧的尺寸对于传输来说太大。因此，性能依赖于对帧的编解码。 -the two procedures can be used in LAN/Intranet (or the Internet) for video conferencing. Now there are many video conference proceedings, each have their own performance enhancements. The main problem is video conferencing video frame size too large for transmission. Therefore, the performance depends on the right frame codec.
