Downstream Frequency Space

I typically see downstream DOCSIS channels in the 500-700MHz range and was wondering if this is because of best practice or some other reason? We're considering giving our frequency space a new home, ~200MHz

I believe that analog

I believe that analog channels are typically located below 550MHz, digital above.

Not sure if there is any performance reasons for this. Perhaps it is more related to historical TV channel plans.

CMTSes are probably at the upper end because it could be difficult to find enough contiguous space lower down?

Our CMTSes downstreams use 3xx MHz, and it works fine.

Thanks for the feedback.

Thanks for the feedback.

It didn't look like we'd be violating DOCSIS spec, but I just wanted to see what the community had to say. Thanks again.
