There was a phone on port 1 when it was defaulted, which is why I thought it was not right that I wasn't able to program from there. I have all the dip switch and jumper settings per the manual, this was a test working CPUP in the Adix. I wanted to test the default/load procedure in the shop since I had time, and to test a few spare CPUPs. When I did the procedure I mentioned it loaded everything without error - I know that's not by the book. When I'm back in the shop later I may swap the phone on port 1, try different CPUPs, etc. Thanks for the reply.

On a different note - last week I moved a ZTD system to a new building!
