| Re: 9 mbit might be in out future?! you're wrong. 2.0 conversion won't come until next year. 1.1 is coming this year. Which means they will have to replace my 1.0 modem.

"In fact Comcast has encountered some "good" surprises, according to Fellows — such as the old Tele-Communications Inc. plant that actually had been rebuilt to 750 Megahertz, but had been mislabeled as less than that.
The typical Comcast plant is rebuilt for 860 MHz with 860-home nodes, he said.
Even a 750-MHz plant can offer 84 analog channels, 216 digital channels and eight channels for HDTV, Fellows said.
Across a 1,000 home neighborhood, that 750-MHz plant could handle VOD for 400 digital subscribers, 400 high-speed-data homes and 300 telephone subscribers, with three 6-MHz slots still left over.
"If we need more capacity, we can split up nodes four ways" and provision the forward and reverse path separately, depending on the capacity required, said Fellows.
Comcast is upgrading all of its DOCSIS 1.0 plant to DOCSIS 1.1 this year, he said. "We have DOCSIS 2.0 in our back pocket, which would give us five times the speed upstream."
Voice-compression advancements are also on tap in the circuit-switch telephony operations Comcast inherited from AT&T. Technology exists to take the voice compression from 64 kilobits to 16 kilobits, allowing Comcast to carry four times as many phone calls on a single line.
Fellows also talked about Comcast's digital transition plans. Comcast could go to 100% digital for its cable network carriage and keep must-carry and retransmission-consent channels in the analog domain, he said.
Such a transition would give Fellows 60 to 80 6 MHz slots to use for other services.
