想必每个人都已熟悉办公室墙壁上分别为电话线和五类网线提供的 RJ-11和RJ-45接口,现代的办公环境已形成这样的典型模式:一个以小型 PBX 为核心的电话网,和一个以交换或路由设备为核心,由网卡和 PC 机连接组成的局域网。两个网络完全独立,分别布线互不干扰。有没有人想过把两种网络合一呢?一定有的,有过布线经验的人更会这样想。谁都不喜欢脚下堆着杂乱的线缆,并且一旦实现双网合一又为语音和数据融合提供了物理条件。由此,网络电话(Networked Telephony)解决方案应运而生——在一个数据网上同时支持语音和数据传输,改变了以往电话网和数据网单独设计单独布线的惯例,使企业内部网也向全 IP 的方向发展。
Presumably everyone is familiar with the RJ-11 and RJ-45 interfaces provided on the office wall for telephone lines and CAT5 cable respectively. The modern office environment has become such a model that a telephone network centered around a small PBX and A switching or routing device as the core, by the network card and PC connected LAN. Two networks completely independent, respectively, wiring without disturbing each other. Has anyone ever thought of merging two networks together? Someone who has experience of cabling would think so. No one likes clutter of cables at the feet, and provides the physical conditions for voice and data convergence once dual-network integration is achieved. As a result, Networked Telephony solutions emerge as the times require - supporting both voice and data transmission over a single data network, changing the convention of separate wireline and data network design for individual cabling, enabling intranet to provide full IP The direction of development.
