16-QAM to 64-QAM Sign of DOCSIS 3? Santa Cruz,CA Area.My internet went out for about 15 minutes. I check on the Modem status page and I've moved from 16-QAM to 64-QAM for the upstream. |

We have 16 QAM on one upload channel and 64 QAM on the other here in Mendocino County. Do you guys have multiple upload channels yet down there? |

Not sure. netcool form PM told me that 2 channel bonding was coming to this area today.
I need to get get a Docsis 3 eMTA to confirm. I just had a hour pointless chat with comcast live chat. Need to wait form them to open. |

Maybe. I had a talk with a supervisor that said I would be changed to have my eMTA replaced because a tech must visit to replace a eMTA. I then had a 40 minute fight with them saying my modem is not Docsis 3 and they kept telling me it is. This speed test is with a DOCSIS 2 Modem

its not a definate sign....64qam return has been VERY common for well over 5 years now.....most places run both 64 and 16 so for all a normal person knows you could have had both, but your modem was just defaulting to the 16.... |

Alright I'm on DOCSIS 3 now with two downstream channels. |
|
RR ConductorRidin' the rails Premium Member join:2002-04-02 Redwood Valley, CA |
Congrats! We only have 2 on the upstream here in the Ukiah area, but 8 on the downstream. |

It's about time.
netcool said 4 Downstream channels will come in time. They have some upgrades in this area or will have to move some stuff off he said. I believe we are still on a 625 MHz system.
I feared Arris form previous experiences but the TM722G Proved me wrong! Great eMTA! |

All my download channels are on 550 to 590 Mhz, the upload channels are 306 and 253. |

I think you mean 30.60 and 25.30 Mhz I wish my 40 Mbps upload burst was permanent but it isn't |

64 qam upstream is technically only proof off D2 upgrade which my area did first about 3 months before a D3 implementation was done. You are moving to D3, but I would not get too excited just yet, equipment setup, tests, and learning curves are ahead for the maintenance team. |
|
1 recommendation |
Yes, just a single 64QAM upstream channel would only prove "at least D2."
In pclover's case, his ARRIS modem is showing both multiple, bonded, downstream 256QAM and upstream 64QAM channels which, AFAIK, definitely indicates DOCSIS 3.0. |

I'm in Santa Cruz area, near UCSC campus and am still on DOCSIS 2 CMTS. I have 2 channel downstream bonding, 1 up, 2 down is 256QAM, 1 up is 64QAM. I'm on the 25 down tier but I can't receive that speed even with a D3 Modem. Internet is highly congested during peak hours at the evening that I get only 1 down 1 up. |

I'm having congestion issues during peak hours as well. I am a Arris C4 CMTS Tho. The tech said that I should be getting more downstream channels soon. Not sure about you. |

A CMTS in D2 mode can't bond any channels so you are definitely on D3. They might not have given you the option for faster speeds to upgrade to but the system is D3 regardless. |

Weird. Comcaststeve told me the reason why I am not getting my max speeds is because my CMTS is D2. My CMTS is a Cisco, not sure what that exactly means. |

PM netcool » netcool with your modem mac address and he will tell you what CMTS your on. A local tech told me that Santa Cruz is going to be upgraded to 5 downstream channels hopefully soon to resolve the congestion issues. He said it's possible at the end of this moth or beginning of next month. BTW are your channels on 579 and 585 MHz for your downstream channels? |

im on docsis 3 and my downstream channels are in the low 515000000 to 530000000 range... sooo |

Interesting mine are at 579 and 585 Mhz I also have 3 upstream channels. |

CMTS=the head end at comcast for your area cisco= a large, network equipment company
A couple of the somewhat isolated areas along the CA coast still have older, non D3 equipment, even the cisco D3 CMTS in other areas is not yet IPv6 compliant, but Comcast is working with to reach IPv6 useability. If they can't reach that standard within a few months ComCast will likely replace cisco CMTS with another vendors equipment. either way, your area will likely have upgrades before the end of the year. |

I just emailed the local tech. If he has anything new to say I will post it here.
I also mentioned to him about the congestion issue. Hopefully that will be speed it up but probably wont. |
