Translation Please: Whats Up In The Upstream? Feb 24, 2009
Upstream, with hyper-vigilant plant maintenance, the very best you can do is 64-QAM as opposed to 256-QAM on all-digital downstream channels. The 64-QAM method maxes at 27 Mbps, compared with 38 ... 8 Mbps for 256-QAM. So, a four-channel upstream bond would yield a raw burst rate of 108 Mbps. (Multichannel News)
