Hi GOM,
That's actually quite simple !
The following is an extract of a local (for me) document but which is probably from generic EEC documentation.
Further, there are European Community defined black, white and grey areas to distinguish between areas where no broadband infrastructure exists or is unlikely to be developed in the near term (white areas), areas where only one broadband network operator is present (grey areas) and areas where at least two or more broadband network providers are present (black areas).
PM me for more info if you want.
Kind regards,
Walter
