NO!

A & B Battery stay as they are.

Signal ground becomes 10VAC.

Signal Battery is Ground.

In the new normal condition 10VAC is always present on one side of the buzzer. When you dial a digit, the DICM sends ground.

This is much easier. That Ground now can buzz a buzzer, trip a relay, do whatever...

Sorry for taking so long. I've been offline for a few days.
