  • Wiring a loop back cable

    Hi we have a number of 220E1 that will not be connected to an outside line for some time.

    Is there a way of wiring a cat5e plug to fool the switch? Like some kind of loop back?

    Depends on what you have them programmed for. If it is a T1 (US) then you just have to do a crossover on the relevant T1 pairs and this will work like a loop back, I do not think this will work for a PRI but I have never tried it, not sure about an E1 but it should be easy to test. Have you played with the loop-back settings in the quickview page for the E1s?

      You should be able to loop the blue and orange pairs.

          Just put it to type "CAS", this will get rid of the red alarm on a switch that is not connected to a PRI/T1. Thats what I do. The only downfall is the switch needs to be restarted to change it back to type "PRI" or a quick google search will show you how to make a loopback quite easily.

            I've done this before on a T1 PRI with no problems.

              thanks swilliamson, that worked.

              The only poroblem is that Director is still reporting it as down, even though the port on the switch is green?
