Indeed it is .. we once used around three miles of phone cable overhead

very quiet indeed..

I was once told that the cables on telephone posts are arranged to
form a twisted pair. (I.e. the cables move from insulator to
insulator so that they twist around each other.)

Well they are twisted to stop crosstalk like the wires in a CAT 5
cable..

Pardon my ignorance, but what is an RSL?


Sorry .. Restricted Service Licence a form of short term broadcast
licence usually for FM radio normally issued for some event or other.

In this instance with was used to link two studios together...
Thanks,
