After much fiddling around with the intercom, I can safely dsay I am an expert at wiring up TD series AIphone units!
Of course, Newell, in its infinite wisdom, decided to use non-standard wiring practices.
In the closet, attached to the DE-UR unit they have a double sided terminal strip. This connects the handsets and the door bell unit to the main system component and power. Instead of wiring each handset as the instructions show, they used the terminal strip to swap the "C" line for each unit.
In other word, each handset unit is wired identically (Thanks Michael!) and the main unit swaps the handset number an C wires.
My issue with an intermittent door bell button/chime was traced back to the IF doorbell itself. Water had gotten in (common!) and destroyed the wiring/board. A new unit was installed and the little green LED now lights and the doorbell rings the handset units for a short time when pressed. 2-way communication between each unit and the door intercom is working as well.
My original door intercom cover is body color, the new one is brushed stainless steel. I put back on the old one, but may swap... aesthetics, you know...
If anyone else needs help, let me know.
