Swapped cables at boxes. Moved the phone from Cab 2, Slot 2, Channel 14 to Cab , Slot 10, Channel 10. The light works appropriately. Then, I did an MMC 315 and swapped the extensions so the person got their appropriate extension back. Still working properly.

So, do you think I have a bad 16DLI2 card or could having the 16DLI2 in the extension cabinet causing trouble?
