Every time we got a suspect line into or out of Toll A,
we would pass it down to Toll Test, who would wait half an hour and pass
it back to us as RWT or FNF (right when tested or fault not found to the
uninitiated). Sometimes it became a game of pass-the-buck between the
two floors until someone found the fault. Many's the time I would call a
circuit through and Pat O'Hara (POH) would bounce it back. To break the
monotony, I would sometimes take the fault down by hand and watch them
test it, which normally involved inserting a damp finger into the air or
flipping a coin (heads it's FNF, tails it's a distant end fault). You
will have guessed by now that this is my attempt at humour. Failed again
!
