The first version of it appeared in parts of Sutton Coldfield in 1976,
but some places still had the old tone into the 1990s. The modern one is
of a slightly higher pitch than the 1976 version. Much of Europe uses a
similar tone. The "secondary" dial tone in France (that followed use of
19 when that was the International prefix) was quite similar too.

The 1976 version of the tone came to Hednesford in 1985 - we had only
lived there for a few months and my mother thought something had gone
wrong.
