These are very easy to make and will save you a little bit of time and money in the long run.How to perform a Loopback Test with Windows HyperTerminal Remember: A T1 loopback plug is for T1 ports it will not work with Ethernet ports and vice versa. Take slot 1's end and place it into slot 3 and take slot 2's and place it into slot 6. Place a wire end into slot 1 and another into slot 2. The only thing that changes is the pin count. To make an Ethernet Loopback Plug do this:įollow the exact same steps above. I put masking tape on these wires just for easy handling when removing it from the port. So the short description is 1 to 4 and 2 to 5 and you will have about 6 inches of wire hanging out. Insert slot 1's other end into slot 4 and slot 2's into slot 5 and terminate or crimp the end. Insert one wire into slot 1 and the other wire into slot 2. The slots are numbered with the clip facing down towards your feet 1 - 8. I like to use the dark colors just so I can see where they are going in the RJ45 end. Usually it's blue, grey, yellow or green.

They inadvertently crossed the tip and ring set and it was an easy fix.Ĭut about 1 foot cord of twisted pair and strip off the casing that holds all the pairs together. With the cable coming from the jack to the router it was red. I plugged in the loopback plug and the status was green. That was one part of the trouble shooting was to see if the T1 module on the router was operational. Loopback plugs are not only great for loopback tests, but they can save a little bit of time to see if a port is working without consoling in. In doing so I created loopback plugs on the fly to test the ports for connectivity. Well the one T1 was not working and I had to trouble shoot what was going on. There were two T1 lines that needed to be routed before the VLAN's could be configured. The other day I was installing a router and switch that needed to be trunked to a preexisting switch and a new firewall.
