Dexman - Moved it to different locations within the office.
dagwoodsystems - Fluorescent lighting is off. I have the processor grounding screw connected to the ground at the electrical outlet. Is this the proper method?
Grim - Tested alternative circuit, swapped out UPS, unplugged laser printer and other appliances.
The click remained.
You guys may kill me for this next part:
Because the click only happens on x10 and x11, I had ruled out a phone line problem. Today I unplugged our main phone line from the processor, connected it to a regular phone, dialed out and heard the clicking. I immediately called Embarq repair service and scheduled a service call - and the customer service rep could hear the clicks on her end.
Could I have spent hours and hours chasing a problem that wasn't there? We'll find out after Embarq visits. I'll let you know.
Thank you again for all of your ideas.
Bart
