eoc排故经验（eoc排故经验） EOC exclusion experience (1) - order of arrangement Hello, I hope to use this platform to share experiences with you. Here according to the personal experience to write some basic EOC judgment process, if have the wrong place please correct the master. Preparation materials: 1 、 equipment and tools needed for maintenance Field strength instrument, connector and tool, MOCA tester (optional), mobile phone or computer with routing (optional) 2. Install Speedtest (speed measurement) and WIFI analyzer (signal analysis) on mobile phone or computer Investigation procedure: One, enter the door three see The terminal indicator, whether there is routing and how to link the incoming line If the terminal cat doesnt have a light, it proves that the link is blocked. It is necessary to check the optical node, whether the EOC device is added, whether the link interface is correct, that there is an inappropriate model (such as overcurrent) in the intermediate link, amplifier and link device. When you have a router, you can no longer dial it through your computer. You need to unplug the route, link directly to the users computer, or bring your own device to detect the network When a link is present, it is necessary to check whether the link line specifications are appropriate and whether the joint links are standard and so on. Put an end to barbaric wiring and tandem connection. Two test signal The frequency field 610MHZ and 714MHZ frequency are tested by field strength tester to ensure that the corresponding values of level, MER and BER are within the range. (select) use MOCA tester to test the MOCA terminal signal value in the line, and observe the attenuation, uplink and downlink bandwidth and modulation system. Three, according to the fault phenomenon to determine the fault point 1, first ensure that the above indicators are normal, and use the computer dial-up (or test accounts) to observe the link status and speed delay indicators. If dialing 651 or 678, go to
