摘要： An unbundling demarcation device (UDD) is disclosed for disconnecting the equipment of a local exchange carrier (LEC) from a subscriber in order to permit a competing local exchange carrier (CLEC) to provide local service to the subscriber. The unbundling demarcation device (UDD) and related CLEC equipment may be positioned at any point in the subscriber loop, between the LEC switch and the subscriber equipment. The unbundling demarcation device (UDD) is an electro-mechanical or electro-optical coupling device, such as a sensitive relay, a latching relay, a switching mechanism or a solid state device that simulates a relay. The unbundling demarcation device (UDD) connects the LEC equipment to the CLEC equipment when a voltage or other trigger signal is applied to the subscriber loop by the LEC. When the voltage is removed from the subscriber loop, or when a deactivating signal is sent, the unbundling demarcation device (UDD) will open circuit or decouple, preventing the LEC from accessing the subscriber equipment and allowing the CLEC to access the subscriber. The unbundling demarcation device (UDD) can be utilized to determine whether there is a fault in the subscriber loop up to and beyond the unbundling demarcation device (UDD). With no voltage applied, the unbundling demarcation device (UDD) disconnects the CLEC equipment, and the LEC can evaluate the subscriber loop all the way to the unbundling demarcation device (UDD). With the voltage applied, the LEC can evaluate the CLEC loop and customer equipment for faults as well. Unlike electronic MTUs, the unbundling demarcation device (UDD) does not present a lossy device when deactivated.
摘要翻译： 公开了一种用于从用户断开本地交换运营商（LEC）的设备以便允许竞争的本地交换运营商（CLEC）向用户提供本地服务的非绑定分界设备（UDD）。 非绑定分界设备（UDD）和相关的CLEC设备可以位于用户环路中的任何点，LEC交换机和用户设备之间。 非绑定分界装置（UDD）是一种机电或电光耦合装置，例如敏感继电器，闭锁继电器，开关机构或模拟继电器的固态装置。 当LEC将电压或其他触发信号施加到用户回路时，非绑定分界设备（UDD）将LEC设备连接到CLEC设备。 当从用户环路中移除电压时，或者当去激活信号被发送时，非绑定分界设备（UDD）将打开电路或解耦，防止LEC访问用户设备并允许CLEC接入用户。 非绑定分界设备（UDD）可以用于确定用户环路中是否存在直到并超过非绑定分界设备（UDD）的故障。 在没有施加电压的情况下，非绑定分界装置（UDD）断开CLEC设备，LEC可以将用户回路一直评估到非绑定分界设备（UDD）。 随着施加电压，LEC也可以评估CLEC回路和客户设备的故障。 与电子MTU不同，非绑定分界设备（UDD）在停用时不显示有损设备。

摘要： A surge protector for an electrical line is disclosed. The surge protector includes a pair of conductive pins respectively connectable to electrical lines. A first pin is soldered to a lead from a gas tube surge arrester. The lead is further fixed adjacent to the first pin and then attached to the second pin. A ground bracket having an opening is positioned between and connected with the other side of the surge arrester. As an electrical surge travels through the lines, the gas tube surge arrester begins to spark over, shunting overload conditions to the ground bracket. As the temperature begins to build, the solder flows, causing an open condition in which the surge arrester disconnects from the first pin, thereby eliminating the destructive effects of a prolonged electrical surge on the lines.

摘要： The invention is a surge protector which can provide voltage and current protection in coaxial cable systems. The protector includes a central conductor which is coupled in series with a variable resistance, and a voltage surge arrestor which is coupled between the conductor and the housing of the protector. A capacitor may also be coupled in parallel with the resistor. The protector provides both an ac and dc signal path.
