Hi Arthur,
Thanks for the help.... To answer your questions.
I hear tones, they sound correct, but CBDT and this only happens on the 4 lines, intercom line work fine.
This phone is a WECO 2564 and I have swapped phones and other phones work fine.
Will check the voltage and current this weekend.
I don't have a butt set but I did rig up a regular phone and tested the lines at the KSU and it work just fine.
The spade lugs are attached to the connector board, I have attached a photo.
Thanks Brian
