[0045] In order to integrate more functions into the measuring instrument, the utility model is designed to share one RJ45 port, and to have an electronic circuit that can perform both line search and line alignment functions at the same time. This saves space for product design and time for user measurement. It brings a simpler and faster measurement experience for network installation and maintenance personnel.

[0046] When the utility model is in use, the alignment function is realized by the alignment circuit of the host and the remote circuit of the receiver.

[0047] When realizing the line-finding function, the line-finding transmitting circuit of the host cooperates with the receiver circuit of the receiver. The line-finding circuit of the host outputs a medium frequency (300Hz~3Mhz) modulation signal from MCU-SCAN-S, which is amplified by HC125 and outputs the line-finding signal. MCU-SCAN-C is the output control of the line-finding signal.
[0048] Because the line sequence detection result is indicated by the LED running light, when the line search function and the line alignment function are implemented at the same time, the line sequence detection result LED light indication will be affected by the line search signal, causing the line alignment LED indicator to flash randomly, seriously affecting the indication of the line alignment result. To eliminate the interference of the line search signal on the line alignment indicator, a 100NF~10uf capacitor is connected to each line alignment indicator. Because the capacitor blocks direct current and passes alternating current, it can filter out the influence of the intermediate frequency line search signal and will not form a voltage difference on the line alignment indicator, causing the line alignment indicator to flash randomly, thereby achieving the compatibility of the two functions of line search and line alignment.
