People in urban areas are usually connected to the internet via physical plant consisting of coaxial cable optical fibre and electronic components such as amplifiers, diplexers and directional couplers/taps arranged in such a way as to allow one coaxial cable to be used for both inbound and outbound traffic. This plant connects cable modems and TVs in a subscriber's residence to a cable modem termination system located on the service provider's site. The entire system, including the software that controls it, is referred to as the CATV network. A standard known as DOCSIS, the latest version of which is 3.1., controls the structure of both the software and hardware of the CATV network and specifies the functionality of all the components used in the network.

城市地区的人们通常通过物理设备连接到互联网，该物理设备包括同轴电缆光纤和电子组件，如放大器，双工器和定向耦合器/抽头，其排列方式允许一条同轴电缆用于入站和出站流量。该工厂将用户住宅中的电缆调制解调器和电视连接到位于服务提供商现场的电缆调制解调器终端系统。整个系统，包括控制它的软件，被称为CATV网络。一个被称为DOCSIS的标准，其最新版本是3.1。控制CATV网络的软件和硬件的结构，并指定网络中使用的所有组件的功能。
