There was a recent notification of work in my area from Virgin Media Business. I asked my contact in VMB what the work actually was and was told it was to upgrade the area to a 32 downstream channels and is one of the first areas to receive that change.

I thought it odd, since current CPE only supports 24, and wondered if he was mistaken.

Prior to the upgrade the Hitron device I have shows the full 24 downstream channels (and 3 up). THe Hitron has slots 1-24 and also the channels IDs were previously 1-24. However I now see that after some reboots slot 2 will list channel id 5 and the channel numbers go up to 28 currently, at a higher frequency than I have seen before, this would seem to support a channel group of larger than 24....
