    • The present invention provides two subscriber line testing systems, three broadband/narrowband telecommunication systems and a broadband line card. In the subscriber line testing systems of the present invention, a test module is configured in the CO broadband device, reducing the complexity and the cost of the subscriber line testing systems. In the broadband line card provided by the present invention, line capturing relays are configured in the broadband line card so that the LPF card can be designed as a passive device to reduce corresponding costs, thus using this broadband line card helps reduce the complexity of the CO broadband device and the subscriber cost thereof. In the three broadband/narrowband telecommunication systems provided by the present invention, by using the subscriber line testing systems and the broadband line card, the complexity of broadband/narrowband telecommunication systems and subscriber cost thereof are also reduced. In the third broadband/narrowband telecommunication system provided by the present invention, both the broadband line card without line capturing relay and the broadband line card with line capturing relay can be incorporated so that a better compatibility is provided.
    • 本发明提供两个用户线路测试系统,三个宽带/窄带电信系统和宽带线路卡。 在本发明的用户线测试系统中,在CO宽带设备中配置测试模块,降低了用户线测试系统的复杂性和成本。 在本发明提供的宽带线路卡中,在宽带线路卡中配置线路捕获中继,使得LPF卡可以被设计为无源设备以降低相应的成本,因此使用该宽带线卡有助于降低 CO宽带设备及其用户成本。 在本发明提供的三个宽带/窄带电信系统中,通过使用用户线路测试系统和宽带线路卡,宽带/窄带电信系统的复杂度和用户成本也降低。 在本发明提供的第三宽带/窄带电信系统中,可以并入具有线路捕获中继的宽带线路卡和具有线路捕获中继的宽带线路卡,从而提供更好的兼容性。

    • A printed circuit board (PCB) has a single sided “U” shape circuit soldered with a light emitting diode (LED), a conducting spring soldered to an open end on the reverse side. PCB based LED mounted inside a conducting shell to emit light toward a light guide tube by magnetic attraction realized by a conducting member having a conducting pole; a refill fits through the light guide tube, and a magnet mounted inside a cap member. One lead of the LED electrically connected to an anode of batteries, the other lead electrically connected to the conducting shell. But the batteries are insulated from the conducting shell; a cathode of the batteries electrically connected to the conducting pole, which is insulated from the conducting shell, as the magnet attracts to the conducting pole and conducting shell by magnetic attraction to conduct an electric current, the LED is lit up for illumination.
