    • A network interface device includes a base, a cover and a circuit board secured in the base. The circuit board includes terminations for input and output communication lines. Each pair of input and output communication lines corresponds to a single standard telephone line, a high speed data line or other type of line. The communication line terminations may be implemented as insulation displacement connectors, and the cover may include projections on its inner surface such that closing the cover also closes the insulation displacement connectors on the circuit board. For each communication line, the circuit board may include a subscriber bridge which establishes a breakable connection between the input and output line terminations via traces in the circuit board. In fixed wireless, fiber-to-the-home (FITI) and other similar applications, the circuit board may also include terminations for input and output power lines, and the base and cover may be extended to accommodate an uninterruptible power supply. The power supply supplies the input power line to the corresponding termination on the circuit board, and the output power line is supplied to a power input of a remote unit in a fixed wireless system or other electronic unit external to the network interface device. The circuit board may also include power protection circuitry for protecting against surges on the input and output communication and power lines. The network interface device may further include a battery back-up associated with the power supply.
    • 网络接口设备包括底座,盖子和固定在基座中的电路板。 电路板包括用于输入和输出通信线路的终端。 每对输入和输出通信线对应于单个标准电话线,高速数据线或其他类型的线。 通信线路终端可以被实现为绝缘位移连接器,并且盖可以在其内表面上包括突起,使得关闭盖也封闭电路板上的绝缘位移连接器。 对于每个通信线路,电路板可以包括用户桥,其通过电路板中的迹线建立输入和输出线路终端之间的可断连接。 在固定无线,光纤到家庭(FITI)和其他类似应用中,电路板还可以包括用于输入和输出电力线的终端,并且基座和盖可以被扩展以适应不间断的电源。 电源将输入电源线提供给电路板上的相应终端,输出电源线被提供给固定无线系统或网络接口设备外部的其他电子单元的远程单元的电源输入。 电路板还可以包括用于防止输入和输出通信和电力线上的浪涌的电力保护电路。 网络接口设备还可以包括与电源相关联的电池备份。
