    • A telephone network interface device utilizing network termination modules for interconnecting telephone company wiring to the wiring of respective subscribers incorporates an improved organization of elements to reduce the cost of such elements; to facilitate their use; and to improve the flexibility and compactness of the organization. The device incorporates an improved hinge arrangement for use with the internal security closure that permits ready removal of the closure to facilitate servicing the installed equipment. A novel ground bus organization comprising an assemblage of bus sections of uniform length arranged to accommodate the length of stack of network termination modules housed in the device reduces the variety of ground buses required to accommodate module stacks of various size. Moreover, an improved connection between the respective modules and the ground bus sections insures correct positioning of the modules within the device and reduces the danger of inadvertent disconnection of the modules from ground. A particular form of network termination module is utilized which permits ready transfer of subscriber wiring between available network interface jacks in the device. The subscriber wiring is connected via a detachable terminal strip secured by a releasable latch which is concealed beneath a dedicated closure cover that is mounted for movement with the terminal strip. Transfer of terminal strips between interface jacks is enhanced by a wire routing arrangement including wire guides of particular design that enable access of all terminal strips with every interface jack without need for wiring disassembly.
    • 使用网络终端模块的电话网络接口设备用于将电话公司布线互连到相应用户的布线,结合了改进的元件组合以降低这些元件的成本; 方便他们使用; 并提高组织的灵活性和紧凑性。 该装置包括改进的铰链装置,用于与内部安全闭合件一起使用,其允许准备移除封闭件以方便维修所安装的设备。 一种新颖的地面总线组织,其包括具有均匀长度的总线部分的集合,其布置成适应容纳在该装置中的网络终端模块的堆叠的长度,减少了容纳各种尺寸的模块堆栈所需的各种接地总线。 此外,各个模块和接地总线部分之间的改进的连接确保了模块在设备内的正确定位,并且减少了模块与地面意外断开的危险。 使用特定形式的网络终端模块,其允许在设备中的可用网络接口插孔之间准备好传送用户布线。 订户线路通过可拆卸的端子条连接,该可拆卸的端子条被可释放的闩锁固定,隐藏在专用的封闭盖下面,该封闭盖安装成与端子板一起移动。 通过电线布线布置来增加接口插座之间的端子排的传输,该布线布置包括具有特定设计的导线器,其能够使所有接线端子板与每个接口插座接入而不需要布线拆卸。
