Abstract --- Media transmission link analyzer is created to upgrade the link test strategy decision and test capability simultaneously. The media transmission link analyzer outfits the link network assessment by methods for high and low level firing. By shifting or changing the circuit design, it can test the working of link as indicated by convention. The tester is embraced with a compound socket terminal node, which is appropriate for compound cables with communal lines and the examination output can be accessible simultaneously according to the Probablistic Road Map method (PRM). There are many types of cables for electric power and telecommunication, the interface definition is complex because all each cable differs by the unique physical layer, topology and size of the cable. Usually, people use a multimeter to check the cable fault. In this test analysis, all the leads of the cable should be tested one to one. This method provides various drawback of more testing time, difficult operation procedure and indirect result declaration. So as to improve and normalize the test technique and to advance the test capability, improving the throughput of the links, a simple worked and compact media transmission link analyzer is intended to inspect the status of correspondence interfaces and graphically give the test outcomes simultaneously.
