DSS not responding

[bzgal]

I'm working on a legend r6 and the DSS of the DLC operator isn't lighting. She has an MLX 20D phone and I've renumbered the pages of the DSS to 7600-7650 for page 1 and so on. My dial plan is 7600-7799 for extensions. I've tried to test the extensions and the phone lights up but the DSS doesn't. When I connected the DSS itself I used the cable that came with it so I don't understand what it could be. Any suggestions?

You could try testing it with the *00 test function. Press Speaker with an SA key selected, you should hear system dialtone, then press *00 and all the keys should light up on the MLX20L and the DSS. If not you may have a defective DSS or MLX20L set. I have experienced both causing the other to fail. At one point I went thru 3 consoles and 3 DSS sets before I had a working pair. I was told by Avaya support that they have had this happen in the past.

You did note that you used the cable that came with the DSS, because that is a special cable just for the DSS.

I just remembered one more thing. Is the cable feeding the jack at the MLX20L 4-pair? It needs all four pairs to work! the -48VDC is on the Brown pair and that supplies the DSS. So that should be checked, especially if you have NO lites!
