BTW, this only refers to upstream, because all the channels that are available to you on the downstream are usually bonded. Each area has a different amount of channels, which is why some people are on 6 7 or 8, some may still be on 4 or 5.
The reason there is only 1 upstream channel is because upstream isn't yet bonded, hence the channel hopping to find the least congested channel. An area will usually have at least two channels.
Channel ID's are just ID's, they aren't an indication to how many channels are available to you.
Your IP and route through the network remains the same, it's just the channel which serves bandwidth which is different. There are differing amounts of users on each channel available to you, so one can be more congested than another.
Power level wise, you are fine, though you are on the upper end of fine. Any higher than +7 dBmV on the downstream and that's classed as out of spec.

Very informative and helpful post. Thankyou kindly. Rep given.
So to extend my understanding of this, can you tell me what "bonded" actually means? I assume when the downstream channels are "bonded" this means they are locked permanently during installation by said engineer to ones superhub? Where as upload channel as you say is possible to change to different ones. Why is the upload not bonded? Why do we have more than one channel for download at all? Do we need them? What does additional channels do? Why also only one for upload? Are they looking to improve the upload by adding channels?
Finally, is there anywhere else I can read about what all of the signal to noise ratio, power levels and modulation stuff all mean? Not that I can affect it, just interested really.
Thanks a lot
