Charter Spectrum → Re: [HSI] Charter speed increases.

Your graphic seemed to show 16, not 24 channels.

He has a 16 channel modem, thus only allowing him to connect to 16 of the 24 channels. But if you look at the Channel ID column, you'll see the actual channel connected to.

Well, the channel ids seem to go past 16.

Finger Lakes in Western NY has 24 Dowstreams and D3.1 active between channels 38 and 53

Channel ID numbers do not indicate the number of active DOCSIS channels.

My cable plant is running 16x4 and the channel ID numbers range anywhere between 49-64.

It has some merit, over in Maine when we went to 16 channels and 24 channels, DCIDs reflected it great. Now, for a while we had only 12 channels and the DCIDs ranged 1 to 12, some had 9 to 16, but that was resolved days after. Of course if you see DCID 64 you probably don't have 64 channels lol, they likely just have them numbered sequentially by the downstream card on the CMTS. In most areas if you see a downstream channel ID of 16, you probably have 16; it's really all someone with a 8ch modem can do. Well, besides keeping rebooting and trying to find them all.

Prior to the recent digital change, BOTH columns showed 1-16. It was after the change that I started seeing different channels.

His modem is only able to use 16 channels but there are 24 channels available in the system.

The first channel is at 531 MHz and channel 24 which is not being used by the modem is at 669 MHz.

Whelp you need a new CMTS your on a legacy Cisco 10012 UBR CMTS which I don't think is DOCSIS 3.1 compatible and the CBR8 and CASA and ARRIS E6000 use ids 1-24 or 9-32 in each bonding group while the 10012 ubr uses a set of up to 16 or 24 channels per group so one group is 1-24 , 25-48 etc

It is not.

And depending on the particular CMTS, the channel ID numbers can be arbitrarily assigned by the operator, so one should always treat the numbers as opaque random numbers and not automatically presume they have meaning.

It is a Cisco CMTS according to the MAC Address lookup info, but I don't know which model or series.

I made the call this afternoon. I have been on Spectrum Ultra for a while and have had 300x20 with my Netgear CM600.

I was informed that the CM600 will handle up to 500Mbps and they upgraded me to the 400Mbps. I will also see a $15 price decrease.

I am at work but when I get home I will reboot the modem and see!

yes but the only CMTS I know that does numbers by MAC domain in groups of how many are bonded and adds from 1-x then, x-16 etc is the legacy 7200 VXR and 10012 UBR from Cisco and those are EOL and as a matter of fact need to be replaced this year if your provider wants to offer more than 16 maybe 24 downstreams as Cisco EOL'd them this year to replace them with the CBR8 my area used to have VXR7200 and UBR10012 my CMTS was a UBR10012 in 2010 when I switched to TWC for DOCSIS 3.0 when it was a single downstream at 783MHz and it got changed to a configuration of 783MHz to 801MHz when DOCSIS 3.0 went live with 30/5 and 50/5 tiers offered about a year later they changed to a ARRIS C4 CMTS and in 2015 it got changed to a E6000 CMTS when they went to 16x4 bonding.

so we could have a case of areas stuck on 16x4 bonding could still be on legacy CMTS gear and Charter can't do an upgrade until they do a CMTS swap.

Thanks for the info. In Brighton, it appears we are now 24 channels as well, if I am interpreting this correctly.

Those signals are pretty bad.
