ADSL2+ uses frequency division duplexing (FDD), ~9:1 ratio (50/448 bins). DOCSIS up to 3.1 is also FDD. Typical EuroDOCSIS 3.0 modem deployments work in 8/4 (max 400/100 Mbit) or 16/8 (max 800/200 Mbit) channel configurations.

Finally 'full duplex' DOCSIS 3.1, renamed to 4.0, promises up to 10Gbps symmetric transfers thanks to echo cancellation (V.34 dialup modem says hi). Of course we barely switched to 3.1 and its unlikely cable networks will jump on the 4.0 bandwagon any time soon.

4:1 is a reasonable ratio for consumer connections, at least. I'm sitting here on a DOCSIS 3.0 modem but it's set up as 10:1. And going up a tier doesn't increase upload speed at all.
