    • A network interface device includes an enclosure that houses active electronics for accommodating twisted-pair telephone wires and coaxial cable. The housing has a base that connects to a building wall. A shield locates within the housing, the shield having a platform and a perimeter wall that extends around the platform. A printed circuit board mounts within the shield between the base and the platform. The shield is hinged to the base so that it may be readily removed with the printed circuit board if repair is needed. A subscriber bridge module mounts on the platform. The subscriber bridge module has subscriber line termination points on one side that electrically connect with the subscriber lines. The subscriber bridge module also has telephone jacks electrically connected between the subscriber termination points and the provider line. This provides a demarcation between the subscriber lines and the provider line. An inner cover encloses a provider line port, any voltage protecting devices mounted on the platform, and power terminals on the subscriber bridge module.
    • 网络接口设备包括容纳用于容纳双绞线电话线和同轴电缆的有源电子装置的外壳。 外壳具有连接到建筑物墙壁的基座。 护罩位于外壳内,护罩具有平台和围绕平台延伸的周边壁。 印刷电路板安装在基座和平台之间的屏蔽层内。 屏蔽件铰接到基座上,以便如果需要维修,可以很容易地与印刷电路板一起移除。 用户桥模块安装在平台上。 用户桥模块在一侧具有与用户线路电连接的用户线路终端点。 用户桥模块还具有电连接在用户终端点和提供商线路之间的电话插孔。 这提供了用户线路和提供商线路之间的划分。 内盖包括提供商线路端口,安装在平台上的任何电压保护设备以及用户桥接模块上的电源端子。
