6.4 mhz upstreams are pretty common. Anytime you see 5120 Ksym/sec channels they are 6.4 mhz. 2560 Ksym/sec are 3.2 mhz wide.

I am guessing they are doing it on a node by node basis? I am on a legacy SG2000 node but where I was a little while ago has nothing but the newer NC4000SG Aurora nodes so that might the holdup for the newer frequencies in my area? Maybe the SG2000 can only do 5-40MHz upstream? |

join:2002-03-06 | My guess would be your node is not congested on the upstream. The original modem might be on a more modem rich node or more upstream utilized node. |

| I don't know but what I have has been the standard for the TWC North Texas upstream plan for all nodes now they are moving to 2 3.2MHz wide and 2 6.4MHz wide. I think my node will be done soon because I have had problems getting 5Mbps up recently on bonded upstream. Also I personally think it has something to do with the nodes as some of the older nodes can only do 5-40MHz upstream and maybe TWC is having to replace nodes in my area before the change it to the top configuration plus I am on a different hub than the original post modem as I am on a hub 34 node while they are on a hub 33 node and it looks like the CMTSs are different for that area so maybe my CMTS is next? I know that my internet wentout last night and rebooted after midnight and no changes on the downstream or upstream occurred neither did the primary channels so I think they are doing it CMTS by CMTS for upgrade and mine might be tonight or very soon said by Jabbu:My guess would be your node is not congested on the upstream.

It's less the bandwidth of the diplex filter (a difference of 2 Mhz isn't a cause to hold this up) and more the type of laser in the node that may restrict upstream channel usage.
FP (Fabry Perot) lasers are more prone to issues with more bandwidth and power being send through them. DFB (Distributed Feed Back) lasers are newer and can handle multiple upstream channels better. The SG2000 node has both types available on its accessory chart.

Beyond the that it just may be a CMTS config change, with no issues at the node holding it up. Or it could be something else is in the way like a upstream carrier for MDU analog channels or city PEG channels on a T8 or T9 channel modulator to get back to the headend for wider distribution.

yeah I was wondering why this all of a sudden but I am thinking it is a config issue and maybe TWC is rolling out slowly But it could be the SG2000 as I have seen several of the SG2000's being replaced by auroras that are on the overhead lines in my area so maybe they need to upgrade the nodes in my area to NC4000SG nodes to handle it. |

| reply to DrDrew
hmm now that you mention it my city is to lose 2 PEG channels soon 95, 96 and both are digital only and they look grainy which I am thinking means TWC is using the return path for sending back to the headend and maybe TWC is shutting them down to reclaim T8 and T9 for upstream use? It would make sense as I am fed out of the distribution hub/headend in my area directly and my aunt may be on a different transport setup in the headend/primary hub. said by DrDrew:It's less the bandwidth of the diplex filter (a difference of 2 Mhz isn't a cause to hold this up) and more the type of laser in the node that may restrict upstream channel usage.

| Well for my area, this is the first time I've ever seen the upload symbol rate at 5.12Msym. It is weird though that my upload frequencies are all over the place, but also that screenshot shows the highest upload freq I've ever seen at 37MHz, so I expect their hardware can't go above 40MHz like you were guessing.

In SoCal we don't have bonding, but I've been on an ATDMA 5120 Ksym/sec upstream since pretty much the beginning.
There was a few months recently where I was dealt a TDMA 2560 KSymc/sec channel shortly after they added 8 downstream bonding, but I'm back to ATDMA / 5120 now. |

North Texas the first market to bond 3 64QAM 6.4MHz wide channels? |
|
| I checked my signals again yesterday and the upload is now the same as your screenshot. I wonder if they are keeping 16QAM on 19MHz for a reason? I also suspect that the use of 64QAM on everything else, assuming the customer's lines are clean and can support, does indicate they may be prepping to increase upload capacity sometime.
