I don't see it either, but twisted pair has been used almost exclusively for POTS since 1900.I know, it should be twisted pair, but I can't see the twists in the pic .
Yea, it's an audio range twist not digital UTP or RF. Good audio cables still work up to the MHz range with proper signal equalization. We had several linking the major comm stations I worked at all terminated on wire punch-down blocks.I know, it should be twisted pair, but I can't see the twists in the pic ... maybe the twisting pitch is too long to be noticeable in such a short segment?
