The BBC and the commercial broadcasters use a common TII numbering scheme. The British practice is for each site to have a unique TII, applying to all transmissions from that site. While the United Kingdom possesses the world's largest network of DAB transmitters, there has been no re-use of TII values, to date, as is the case in some other countries.
Changes were made to the TII codes for certain transmitter sites during 2001. The changes are designed to optimise TII usage and apply to both BBC and commercial sites. Sites affected are Hannington, Waltham, Oxford, Bow Brickhill, Sutton Coldfield, Winter Hill, Turners Hill and Zouches Farm. Both sets of numbering are included here for reference.
