and here's the official version

LCN - Logical Channel Number. The LCN is the digital channel number that is used to select a channel on your box, for example 1 for BBC1 or 80 for BBC News 24. LCNs are constant, just as you might find almost every analogue TV has BBC1 on the first button, BBC on the second and so on. Don't confuse the LCN with the UHF channel; all the channels on a multiplex will have the same UHF channel, but individual LCNs.
And the reciprocal version - identify the transmitter from the channels in use
