Re: Xfinity and Increased Bandwidth Being Low Prioritysaid by randy:Ah, ok. But DAA can't really be deployed until the stuff in the field is also upgraded. It's great to hear that the head end is/has been upgraded, but the field is a lot of stuff. Watch your SNR on your Modem you will know when you are upgraded. I am almost 42db SNR on all 33 downstream channels and I am on a Node + 0 node |

said by uct_4:One person says 5%, you say "nearly all". There is a big difference between the hubs "nearly all" being DAA capable and 5% of nodes being DAA. The hub work is actually the bigger project and absolutely needs to be done first. |

I don't know what Comcast has done here but things are way better than they were even a year ago and things were never all that bad here in the 6 years I've lived here anyway. |

You have been upgraded to either RPHY or a Node+0 or Node +2 for sure. They have reduced the number of AMP's between the Node and your House Tap. I was upgraded 3 years ago and I have ZERO issues since then. Rock solid service.

We traditionally were never one of the first markets to get new speed tiers and we were always way down the list for new equipment when I worked there. |

You’re able to tell whether someone is on a N+? based on a screenshot of their signals? What would someone be able to determine from mine? It was running for over 20 days while I was away and when I returned I still had zero correctable and uncorrectables. I’m in a new area so I don’t have a reference to what’s as previously installed compared to anything new. My modem reports the CMTS as Cadant. |

Or you are very close too the node. You must be on a very small node of users to have such good correctable numbers (ie 0) |

Thank you for replying. It’s an apartment complex. There’s maybe four or five green pedestal boxes sprinkled on the property.
What does it mean for my chances of seeing mid-split and OFDMA? |

Ok cool. Let’s hope Comcast engineering agrees with you and doesn’t make us wait a decade to do it lol. Hopefully we’ll see OFDMA too. |

Well mid/high split is done at the headend, you're likely already on mid-high split capable equipment.. it'll just go on for everyone in your area when they're ready to do it. |
|

You mean when the E6000 is switched over to vCMTS? Isn’t Remote PHY and DAA needed though? |

You are thinking of Analog CMTS. Comcast Mid/High split will occur at the RPHY Node as it is all Ethernet back to the vCMTS. |

Right.. but Comcast likes uniform service offerings.. so likely the equipment will long be deployed before it's "enabled" They're not going to skip Mike's apartment complex and enable mid/high split on all the streets around it... that's just not typically how they do things. Charter on the other hand has no shame lighting up a single city with an upgrade.. Comcast likes to only deploy when a full division is ready. |

And at that point is when we’ll see the CMTS MAC change to something else and not report back as CADANT right? |
