Hello Group!
I will most likely find the answer to this when I return to the problem on Monday,but I wanted to see if this is a known issue....On Satuday,I relocated a VM PC from one location to another within the same building...tested fine after relocation...then cleaned up some very bad wiring in the area where the Comdial common equipment was located.This included remounting 2 ATI-D boxes that were falling off the wall and rewiring their RJ's..I was already late for another job so I didn't re-test the system..later,I called the site.....no answer....(that's not a good sign,I thought)....I stopped back today(Sunday) to re-check my work. Everything was
fine except I had crimped both ATI-D input RJ plugs wrong.Pair 1 had reverse +/- from the correct pair 2 in both plugs...OOPS!...after correcting that...the output side RJ's have good voltage to the VM PC on all four ports...but when a buttset is bridged across them there is no touch-tone burst answer from the ATI-D as it had been doing when it was working.....are the ATI's shot??

A reversal on your tip and ring wont destroy the unit but the system will not reognize it as what it is. Using procom if you go to print outs and do a system print out you will see that the ports were the ati-d are at are not recognized. Reversing the pair should bring it back.

Good Luck!!

Also a system reboot may not hurt it. Remember that and ATI-d must start with an even port first! Hope fully the ports did not get damaged. Try pluggin in digital phone if you think that may of happen!
