How can any cable company call this a godsend for upstream when they don't bother taking advantage of it on any DOCSIS version?
True... in docsis 1 they had 1-way modems in 1.1 they had kilobits & 1-2 megabits up.. in 2.0 they splurged and did up to 5 up.. now it's 8-15 up with docsis 3.0 and channel bonding is FISRT getting to customers THIS year.
Technically, docsis 3.1 was SUPPOSED to be a mere technical FIRMWAREish upgrade.. not replacing cmts/node equip, scrubbing the outside plant for line noise and other expensive plant tasks... but that's what it's turning out to be... much to the annoyance of cablecos. Luckily it isn't as bad as individual line conditioning on copper twist pairs or you'd never see such a quick upgrade.
