You could tap out the local dialling code to an adjacent exchange, and
from there you could tap out, it's local dialling code to an adjacent
exchange ... USW, USW, USW.

IE Leeds Cleckheaton Brighouse Huddersfield Slaithwaite
Marsden Oldham Chadderton Manchester {Local Number]

I wonder what would have happened if one were to dial the codes back and forth
or in a circle back to the starting exchange.
