Re: DOCSIS?
said by pipdipchip  :What version of DOCSIS are they using? DOCSIS doesn't.exist.yet? I highly, highly doubt anyone will be getting 20Mbps download speeds. DOCSIS does exists. DOCSIS 3.0 doesn't

for 20/2 operation.
Presently OOL is using DOCSIS V1.1 headends. Which are
10/1 devices.
DOCSIS V3.0 is a cable modem pipe dream. Nice on paper
but notbody has it yet. |

| Uhm, my 2.5 year old Motorola SurfBoard 4200 is a DOCSIS 1.1 device capable of 24/10 Mbps. Don't understand why would then OOL need to upgrade the network and cable modems to provide 20/2 Mbps? From the cited letter, no device upgrade was mentioned. |

The SB4200 is V2.0 capable (I think) I know the SB5100
is, it's the one I got. Would love to get an invite. |

| The SB4200 is a DOCSIS 1.1 device. »www.cablemodem.com/specifications/ gives the specs of DOCSIS and it appears that the speed promised by OOL is achievable with DOCSIS 1.1. Of course 2.0 is better and backwards compatible so even people with 1.1 devices will probably see speed improvement. |

|  SB 3100 = DOCSIS 1.0 max of 3.0 Gbps down 512kbps up
SB 4100 = DOCSIS 1.1 max of 15 Gbps down 1.5Mbps up
SB 5100/5120 = DOCSIS 2.0 max of 30 Gbps down 3.0Mbps up
SB XXXX = DOCSIS 3.0 max of 150 Gbps down 15.0 up due out in 2007 according to Motorola. WAY ahead of comcast!
The whitepaper did not address caps or burst speeds. |
