    摘要： A current limiter in one exemplary embodiment of the present disclosure has a protection element that protects a current limiting element from excessive power dissipation. The protection element senses a parameter that is indicative of an amount of power being dissipated by the current limiting element. The protection element controls the current limiting element based on the sensed parameter such that power dissipation for the current limiting element is reduced to a safe level during a fault condition thereby protecting the current limiting element from damage during the fault condition.

    摘要： A communication system has a network access device (NAD) that is designed to deliver Plain Old Telephone Service (POTS) along with high-speed data to Customer Premises Equipment (CPE). The NAD is backpowered by the CPE across a subscriber line. When backpower is provided from the CPE, circuitry (referred to as a “POTS signaling element”) within the network access device converts POTS control signaling to digital data for transmission to the CPE. The band vacated by the POTS control signaling is used for the power signal on the subscriber line. In the absence of backpower, components of the network access device are bypassed, thereby providing POTS in the event of a power failure. The NAD receives advance warning of the backpowering so that it can disable the bypassing in order to prevent the power signal from leaking through the NAD to the network.

    摘要翻译： 通信系统具有网络接入设备（NAD），其被设计成将普通老式电话服务（POTS）以及高速数据传送到客户端设备（CPE）。 NAD在用户线路上由CPE支持。 当从CPE提供反向功率时，网络接入设备内的电路（称为POTS信令元件）将POTS控制信令转换为数字数据，以传输到CPE。 由POTS控制信令腾出的频带用于用户线上的功率信号。 在没有反向功率的情况下，网络接入设备的组件被旁路，从而在电源故障的情况下提供POTS。 NAD接收到反向强制的提前警告，以便它可以禁止旁路，以防止电源信号通过NAD泄漏到网络。

    摘要： A telecommunication system has a telecommunication line for communicating a combined signal and a splitter that is coupled to the telecommunication line. The splitter has a high-pass filter, a low-pass filter, and a current limiter. The high-pass filter is configured to transmit a first component signal of the combined signal, and the low-pass filter is configured to transmit a second component signal of the combined signal. The current limiter is configured to limit a current of the second component signal thereby preventing at least one inductor in the low-pass filter from saturating.

    摘要： A combination of algorithms and circuits are used to combine POTS, high-speed bi-directional data, and back-powering onto the drop connection for fiber to the distribution point architectures. A telephone adapter device can be utilized to prevent damage from back-powering occurring at POTS telephones connected to the drop connection. In addition, circuits are used to prevent damage from back-powering occurring at POTS telephones directly connected to the drop connection. A circuit is used to provide more consistent power to the electronics at the distribution point even when the input back-power to the distribution point may fluctuate.
