Canada First To Get Pre-Cert DOCSIS 3.0 Speeds > Yeah

said by odog:

Considering most upstreams are only running in D1.1 3.2MHz QAM16 and thus limited to 10Mbps using a D2.0 6.4MHz 64QAM upstream and a 4 X 256QAM downstream you'd have 160Mbps down/30Mbps up shared among 500-600 users. Upstream channel bonding is definitely going to be killer but traffic is still asymmetrical to the net so downstream is MUCH more important.
