IP 电话向数据中心网络的迁移已经开始。电信公司报告说早在1997年中,公共语音网络上的数据流量超过了语音流量。主要的在建网络都使用了数据基础设施,同时采用了电缆和 xDSLMODEM 等永久的高速 IP 连接。在今后的两年中,这一建造效果将相当明显。中心办公室设备将迁移到混合的数字结构以应付这种新的数据流量变化。随着数据包语音的实现,任何能够应用于网络的程序将都能够承载语音。一个 IP 电话包含下列组件:用户接口、语音接口、网络接口、处理器核心以及相关的逻辑部分。用户接口提供电话的传统用户接口
IP telephony migration to the data center network has begun. Telecom companies report that as early as mid-1997, data traffic on public voice networks exceeded voice traffic. The main network under construction uses a data infrastructure with permanent high-speed IP connectivity such as cables and xDSLMODEM. In the next two years, this construction effect will be quite obvious. Central office equipment will be migrated to a hybrid digital structure to cope with this new data traffic change. With the implementation of packet voice, any program that can be applied to the network will be able to carry voice. An IP phone contains the following components: a user interface, a voice interface, a network interface, a processor core, and related logic. User Interface Provides the traditional user interface for the phone
