it depends on your setup, if using abm for cable only then if you have an 'all channels' bouquet they should be numbered correctly but the other bouquets will be wrong, ie bbc1 in all channels will be 101, but bbc1 in entertainment wont be. If you disable 'Create main bouquet' in abm providers, then you will lose the 'All channels' bouquet but then the numbering in the other bouquets will be correct.
