Require DOCSIS 3 modem?

We are on DOCSIS 1.1 and ONLY 30/5 and 50/5 needs the DOCSIS 3 modem. So, TWC is going to tell Oceanic to throw away all the modems in the field because almost none of them can be flashed to support DOCSIS 3? That's nuts. Why would 15/1 (we don't have 20/2), or 20/2 need DOCSIS 3 modems? 15/1 is fine currently on DOCSIS 1.5. Not only the ridiculously high price tag, but being forced to give up a modem you love will deter many from upgrading beyond 10/1. I have a Surfboard 5100 that is over 7 years old now but I don't want another modem because Oceanic has no Surfboards currently and they won't let me buy my own, so, for this reason, and the outrageous price, I will just stay with the Standard tier. I wanted 15/2 for the reasonable $10 more but 15/1 is not worth $10 more and $20 a month more for 20/2 is getting too expensive.

I don't care what pitiful name TWC decides to call RR now. It will always be Road Runner to me. You'd think TWC could least show a tiny bit of creativity and come up with a decent name since they have decided to show what cheapskates they really are by ditching the Road Runner moniker just because it was costing them a bit of money to have a bit of class. Maybe Oceanic will grace Hawaii with a decent name. We did fight and win against TWC corporate when it tried to force the deletion of "Oceanic" from the legal name of TWC here in Hawaii. So, maybe we can have a contest or something to come up with a nice name to replace the Road Runner name. (Actually, it is simply "Oceanic" to most everyone in Hawaii...we'd like to forget that TWC owns Oceanic cable).

Since D1.x only allows 4 mbit upload on the node giving people 2mbit on Turbo I can see their point. Though, if they replace the modem I'm not sure that would be a huge deal.

I'm in central NY and they said if I wanted to bounce to Turbo (I'm on Extreme now) I'd need to swap modems. I don't need the 5*30 and 2*20 would be my sweet spot but for me its only a few dollars less. So I stay on D3 and have no contention issues like I suspect I would have on the only non bonded D1 channel

They might require DOCSIS 3 to bond channels. This might help them improve network utilization. Depending on usage patterns, it might be better to have 300 folks share a single, fatter chunk of bandwidth vs. two groups of 150 share smaller but separate chunks of bandwidth -- especially as the package's top speed approaches the theoretical maximum of earlier DOCSIS, single-channel capabilities.

I just switched the TWCBC because of all of this mess with TWC residentiall; no static IP, one public IP, having to constantly renew promos. I talked them into a Teleworker plan for a lower speed at a lower price-no contract and no setup fee. I had extream 30/5 with the Ubee DW3611. They just switched the IP remotely to use same moden on TWCBC with only 7/768k service. Speeds are much more consistant on Business Class since the routing is different.

I asked residential if I switched down, could I keep the modem. They said yes when before they had told me I need to change modems. They are slowly allowing you to keep a DOCSIS 3 modem in markets where they have enough installed. I'm sure they are having to recycle them until they can buy enough to replace the older ones like I had before the upgrade.

This story doesn't mention that they are now charging a modem rental fee if you don't have a promo. They are also allowing you to use your own modem in some markets as well. Again, probably a slow change to match what companies like Comcast are doing.

It all comes down to better use of bandwidth on the node. DOCSIS 3 allows for a cable modem to bond or connect on multiple data channels so if they need to add more bandwidth to a node to handle more customers, they can just add more data channels instead of having to split the node which can be very expensive and time consuming. So it really comes down to the fact that DOCSIS 3 allows for much more efficient use of bandwidth on the cable.

Quit spreading misinformation again mele. Your Moto 5100 modem is DOCSIS 2.0 and it's connected to a DOCSIS 3.0 CMTS (otherwise Wideband wouldn't be available in your area) and there is no DOCSIS 1.5. None of the older non-DOCSIS 3 modems can be ever flashed to DOCSIS 3 because it's more than just a code upgrade. It's a hardware change since more physical RF tuners are needed to handle the multiple channels and older modems only had single tuners for single channels use.

The DOCSIS 3 requirement is to better utilize the multiple data channels available due to the DOCSIS 3 CMTSs installed and allow for quicker roll out of IPv6. Continuing to allow new installation of non-DOCSIS 3 modem will just slow down upgrades.

Charter, Comcast, and others are aggressively changing out older modems for DOCSIS 3 models, TWC is somewhat late to do this. A couple months ago, Charter sent me a brand new Moto 6121 to replace my owned Moto 5101. No charge, no monthly rental.

Cablevision didnt need docsis 3 to roll out 30/5 package when they first came out with that package. For 30/5 speeds only docsis 2 was needed.

Sure DOCSIS 2 could support it with a limited number of customers like when it "first came out", but it's much more efficient and scalable to a larger number of customers with DOCSIS 3.

I have concrete proof that we are on DOCSIS 1.1 except for those who have 30/5 and 50/5.

I don't have permission to post the email. I know the Oceanic management person well, it is his job in Oceanic management to know these things, and if this is what he says then that is how it is and I have no reason to go further with it. He is not a poorly trained CSR giving out erroneous information where I might feel it necessary to seek someone higher in the chain to answer questions.

The bootfile can be changed to Oceanic's liking even if the modem is not rated for that DOCSIS version although I don't see how a modem rated for DOCSIS 1.1 could have the bootfile changed to DOCSIS 3 but it could to DOCSIS 2. It might need a firmware upgrade though first. Modems such as mine have the firmware upgrade already but are RUNNING AS DOCSIS 1.1. The firmware upgrade is so that my modem will be able to do IPv6 when that is implemented. Only modems that cannot support DOCSIS 2, after a firmware upgrade, (or the customer subscribes to 30/5 or 50/5) will be swapped out by Oceanic is what I was told by management. Currently, the CMTS is on DOCSIS 1.1 whether you want to believe that or not. Being that a crappy TWC owns Oceanic this could all change in an instant with no courtesy to Oceanic management as to informing them ahead of time. Oceanic is bitterly aware of this but already got punished for bucking TWC corporate a few years ago and won't try to do that again. My point being that as of CURRENTLY what I have stated is correct but that could all change quickly if TWC decides to not allow Oceanic any ability to run its system as it best sees fit. So, you could be right in the future but currently, and in the past when you have erroneously attacked me, you were then and are now wrong.

I know what Comcast is doing and you have mentioned Charter before and getting a DOCSIS 3 modem sent to you. TWC is NOT either of those companies. I won't accept any of the crap shit modems Oceanic is currently giving out. They don't have any Surfboards except the 5100's that are still in operation. I don't know if they are getting any in the near future or ever. I see no reason why my modem would need replacing (as long as it is working ok-Oceanic just corrected speed issues and I now have better modem stats than I have ever had before and Sam Knows reports SUSTAINED -non burst- speeds at or above the cap now) unless I were to subscribe to 30/5 or 50/5 neither of which I can afford or will ever be able to afford. Even 20/2 does not need a DOCSIS 3 modem but even $20 a month more is out of my range, besides, I don't need that much speed on download. I could do the $10 a month more but with the upload so low it was not worth the extra monthly fee. If prices go up in Hawaii then I may have to start doing what so many do on the Mainland and switch back and forth every six months between RR and Earthlink to get perpetual promo deals. Or subscribe to RR Lite.

Edited to correct the two three places where I typed DOCSIS 1.5 when I meant 1.1.

There is no DOCSIS version 1.5, that is... not according to the official DOCSIS worldwide standard set forth by CableLabs, the group behind the DOCSIS worldwide standard.

»www.cablelabs.com/cablemodem/spe···dex.html

According to that page, there is only versions 1.0, 1.1, 2.0, and 3.0. That's it, no version 1.5.

Ah...I keep typing 1.5 when I mean 1.1. This is sadly NOT the first time I've done this and probably won't be the last. Getting old is so much fun.

I did have it typed correctly one time in my post but typed incorrectly twice. I'll edit the post.

From a pure bandwidth requirement, the 20/2 service doesn't need DOCSIS 3 but from an efficient bandwidth utilization standpoint, it would be in the cable company's best interest to make people who have the 20/2 service to be on DOCSIS 3 modems. That way no one person can monopolize a data channel.

It all comes down to more efficient use of bandwidth on the cable.

I wouldn't trust most managers to know how the DOCSIS 3 CMTS installed is actually configured. Now if it was the CMTS Engineer who configured the CMTS or headend tech who knows how it's configured, that's a different story. The only "concrete proof" would be a copy of a config file sent to your modem and/or the CMTS configs your modem is attached to, an email from some anonymous manager isn't either.

CMTS configurations are much more complicated than just DOCSIS 1 on or off, DOCSIS 2 on or off, or DOCSIS 3 on or off. The CMTS can run multiple channels with multiple configurations and dynamically switch between them. A modem can be switched on the fly from DOCSIS 1 to DOCSIS 2 to DOCSIS 3 depending on what the CMTS negotiates with the modem and the capabilities of the modem.

The CMTS may be running 6.4 Mhz upstream channels, 32QAM or 64QAM upstream channels, ATDMA or SCDMA upstream modulation, advanced upstream equalization, or some of the other features allowed by DOCSIS 2 protocols. Some of those features are visible to end users through the modem diagnostic pages (such as upstream channel characteristics), while others aren't.

My modem in TWC land switches between DOCSIS 1 channels and wider DOCSIS 2 channels as the CMTS tells it and I wouldn't know unless I saw it in the diagnostic pages. When I connect a DOCSIS 3 modem, it bonds a few of those channels and goes into DOCSIS 3 mode. If I connect a DOCSIS 1.1 modem, the DOCSIS 3 CMTS is still there and the modem only connects to the DOCSIS 1 upstream channels, but I still get some benefit from the DOCSIS 3 CMTS such as multiple channels the modem can switch between.

Companies (TWC or otherwise) don't normally install multiple $150k+ specialized routers only to turn off all the features that were paid for in the upgrade over the model it replaced.

TWC also doesn't seem to normally push config files that handicap modem features to less than what the CMTS tells it is available and can use, it makes configuring it on the CMTS pretty useless. I've never heard or read TWC pushing config files that instruct DOCSIS 2 modems to ignore DOCSIS 2 channels being offered by the CMTS. Modem bootfiles also can't enable non-existent features on a modem. A modem config file trying to enable DOCSIS 2 features will be ignored on a DOCSIS 1 modem, same for DOCSIS 3 features on lesser modems. The same goes for higher level DOCSIS protocol messages sent from the CMTS to lower level modems.

Anyway, you still have a DOCSIS 2 modem with DOCSIS 2 firmware connected to a DOCSIS 3 CMTS and there never was a DOCSIS 1.5. You're getting benefits from that DOCSIS 3 CMTS whether you realize it or not.

DOCSIS 3.0 is needed for anything above 10 Megabits because of lack of capacity under DOCSIS 1.0. There is no such thing as DOCSIS 1.5. DOCSIS 3.0 has channel bonding, and in most DOCSIS 3 markets TW uses 4x1 Channel bonding configurations allowing for a maximum potential of 152 Megabit/s downstream per node and 27 Megabit/s upstream per channel which gets shared by the number of customers on the node actively using their connection at any given time. TW usually deploys more than two upstream channels but they're not bonded. You can't flash modems to DOCSIS 3, DOCSIS 3 requires a different tuner that can connect to 4 or 8 channels simultaneously. You can buy your own surfboard modem and use it on TW's network look into the SB6141 it provides amazing performance and stability. Please keep your unintelligible comments to yourself.

I'm not saying that it can't be done, you can run 20/2 on DOCSIS 2 but... it's a waste of bandwidth on the cable. All it takes is someone to saturate their connection for a long period of time and that data channel is as good as gone for the rest of the people using the same data channel.

That is why DOCSIS 3 is so good, you can connect on multiple data channels and spread the data across multiple data channels thus reducing the demand on one channel and potentially slowing down other customers on the same node.

Again, it all comes down to the fact that DOCSIS 3 allows for more efficient use of bandwidth on the cable.

I made a typo and I apologized and corrected it. So, how come you are such a SHIT? We are on DOCSIS 1.1 not 1.0 or 1.5 that I mistakenly typed in my post where I ALSO typed 1.1 and then later corrected the mistake I made when typing 1.5. I suppose you are perfect and have never made a typo in your entire life. How nice.

You are the one who should keep your unintelligible remarks to yourself:

A: I am on Standard RR which 10/1. DOCSIS 3 is NOT needed! I will not be upgrading. I plan to stay on 10/1.

B: What does DOCSIS 1.0 have to do with this discussion? Nothing. Why did you bring it up?

C: I never said anything about flashing modems to DOCSIS 3. I think you can't read. I said that Oceanic told me that DOCSIS 1.1 modems can be flashed to DOCSIS 2 so that IPv6 will work with them.

D: Oceanic TWC has NEVER allowed us to purchase our modems. So, why are you saying I should do something that we not allowed to do?

You are the one making the "unintelligible" remarks.

I fully trust the persons (more than one...more than one position at Oceanic both here in Hilo and on Oahu - plant head, technical head, etc several of whom I have personally known (and been friends with) for as long as 37 years (since we first got cable in my building). I don't believe for one minute that they are lying and you, who don't even live in Hawaii, know more about Oceanic than they do.

Well, with the recent changes that TWC has been trying to push it seems that they are trying to consolidate their Internet plans on a nationwide basis, at least in all the territories that they operate including your Oceanic group. If TWC has a hand in it, like the Oceanic group as you say, they will most likely end up being pressed into changes that TWC has been pushing to other territories that they run. This will include standardizing the hardware and configurations used in all of their footprints including all the headend equipment, CMTS, and node hardware in the field.

What does this mean for you as an Oceanic customer? Probably a more consistent service lineup that is more inline with the rest of the TWC company. Other territories are starting to allow users to own their own cable modems minus support for them. Most likely you will see the same option to do so in the future with the consolidation that they are trying to do across their markets.

I've tried to stay civil in this conversation and maintain my posts with facts, nothing else.

Pay attention to your modem's data channels, I'm sure you'll find them changing occasionally. When it does make a note of the channel ID, frequencies, modulation type, and symbol rate.

Look for upstream modulations of 8, 32, or 64 QAM; symbol rates of 5120, and/or ATDMA or SCDMA modulation. Any of that is a sure sign of DOCSIS 2 being used.

BTW, I never said the people you were talking to were lying, I said I wouldn't trust them to know.
