    If I understand correctly it’s not intrinsic to the DOCSIS standards, it’s just how more or less every cable company chooses to allocate channels. Think like a cable company has 100 channels they may be able to use on a given line, and they choose to put 90 of them on download and 10 on upload (numbers are made up to convey idea). Now they have only a small amount of available upload bandwidth and lots of download, but they could have set it up to be 50/50 to have it be equal.

      DOCSIS 3.0 and 3.1 allocated much less frequency for upload bandwidth than for download bandwidth,and yes it is written in to the spec. I believe 4.0 allows the ISP to change which parts of the spectrum are used for upload and download. Comcast has just this month started their first DOCSIS 4.0 deployments, and they are offering 1000/1000 on those plans
