Well if the house is built in the 70's the cable is old 2 pair wire, meaning that there are 4 coloured wires (red, green, yellow, black).
If you cut the sheathing off (Carefully without cutting the cables) you can see the colours of the cables.
The first pair of wires to use are the Red and Green.
The second pair of wires to use are the Yellow and Black.
If you hook up the red/ green wires to a voice jack, these cables might possibly be hooked up to the main telephone terminal (usually found downstairs) and you will have telephone service to the jack.
But not knowing where the cables are attached to this is hard to say.
Might be alot easier if you call in your telco provider to get them to install this jack.
Good Luck.
