My home has phone wiring (on the phone company side) that is state-of-the-art 1950's technology.
To be specific, I an receiving three conductors into a 305A box.

Now, Ive had the line from the box, into the house, cut / trashed any number of times. Accident, malice, animal action ... you name it. This spring I'm looking to re-route the line in a more sheltered path.

Now ... perhaps someone could save me a lot of 'hit and miss' and tell me which wire goes where?
The wire I'll use, and the jacks in the house, will be Panduit "Cat 5", since I carry those on the truck. (Think of the cable as '3 wires and 5 spares [Linked Image])

Which three of the four center wires goes to which screw on the 305A block?
