Thanks for your helpful reply.

The reason I asked was when I was researching this to better understand things, I came across this on the Wikipedia page:

https://en.wikipedia.org/wiki/DOCSIS

Quote:
Throughput

The first three versions of the DOCSIS standard support a downstream throughput with 256-QAM of up to 42.88 Mbit/s per 6 MHz channel (approximately 38 Mbit/s after overhead), or 55.62 Mbit/s per 8 MHz channel for EuroDOCSIS (approximately 50 Mbit/s after overhead). The upstream throughput possible is 30.72 Mbit/s per 6.4 MHz channel (approximately 27 Mbit/s after overhead), or 10.24 Mbit/s per 3.2 MHz channel (approximately 9 Mbit/s after overhead).
so I was curious if the 2 channels we have now can, in the real world, be pushed to get nearer these theoretical limits (2 channels ==> 54Mbps). The only reason I went to 350/20 is for the upload and so if our CMTS is stuck on 2 channels for the time being, would this preclude higher uploads even though, on first reading, the DOCSIS page hints at more.
