2 Shaw Docsis Modems on 1 cable outlet in Shaw http://www.dslreports.com/forum/r15601461 en Sun, 29 Nov 2009 04:24:37 EDT Sun, 29 Nov 2009 04:24:37 EDT Re: 2 Shaw Docsis Modems on 1 cable outlet http://www.dslreports.com/forum/remark,15650007 DRNO22 : Well from what i gather 1 modem could be setup to do it, its more for wow factor having 11 modems than anything. It actually works out well with all the modems as we can tcp stream balance the load across the modems. I dont have traffic graphs in front of me but the bottom end of the graph is in the 2000-2500kb/s range with the peak around 8000 kb/s

Still trying to get a hold of a picture, once i get one i will post it.]]> http://www.dslreports.com/forum/remark,15650007 Thu, 09 Mar 2006 17:22:10 EDT Re: 2 Shaw Docsis Modems on 1 cable outlet http://www.dslreports.com/forum/remark,15646147 Ignite :

This setup from SHAW is not normal. It is setup specifically for our event. I cant go into any details but we have alot more than 30mb bandwidth available.

And you would be surprised how many poeple at a large lan want net access. With games like WOW ect around i dont think you will find many lans that run without it.
Nice set up if you can get it, weird one too though if they set the network up specifically to give you guys more bandwidth but require you to have 11 cable modems.

No need to go into huge detail with it it's fairly self evident how they're doing it, options are a bit limited how to do it :)

Feel privileged though there's a fair bit of equipment supplying your bandwidth :)]]> http://www.dslreports.com/forum/remark,15646147 Thu, 09 Mar 2006 04:15:17 EDT Re: 2 Shaw Docsis Modems on 1 cable outlet http://www.dslreports.com/forum/remark,15646129 Ignite :

A simple 'ooops I was wrong' would have sufficed rather than getting indignant :uhh:

You posted what you believed to be the facts, someone else posted what they actually were, it happens.

Any pissing contest arose from your providing technical explanation of what you considered to be these facts, and a technical argument is best countered with another one.

I'll make a mental note to stay quiet whenever you post if being disagreed with on a discussion forum is that offensive to you.]]> http://www.dslreports.com/forum/remark,15646129 Thu, 09 Mar 2006 04:04:37 EDT Re: 2 Shaw Docsis Modems on 1 cable outlet http://www.dslreports.com/forum/remark,15644913 onk1 : I'll take a dual node with two uncapped modems plz]]> http://www.dslreports.com/forum/remark,15644913 Wed, 08 Mar 2006 22:45:36 EDT Re: 2 Shaw Docsis Modems on 1 cable outlet http://www.dslreports.com/forum/remark,15643975 Mac Write : Come on you gotta spill the beans. :D We want details. :D Get us pictures from this years LAN Party.

Let me get this straight - a node with 1,000+ customers on it only has a max downstream of 30mbps-38mbps? and 30mbps up-stream? Geez that's serious over-selling and 5 people downloading at max speed would kill the node. Please tell me this isn't correct.
Oh it be so sir, and they are quite unlikely to have 30Mbps of upstream available :D

1,000+ customer nodes are unlikely I hope, usual builds now use far smaller homes passed per node. More recent UK overbuilds have been 250 - 350 homes passed per node.

Think about it this way the MSOs offering 15Mbit it only takes 2 people doing full speed and one doing half to max it :D]]> http://www.dslreports.com/forum/remark,15638204 Wed, 08 Mar 2006 02:55:14 EDT Re: 2 Shaw Docsis Modems on 1 cable outlet http://www.dslreports.com/forum/remark,15638201 Ignite :

EuroDOCSIS is based on a 8MHz RF channel hence it's greater downstream capacity. As far as my statement regarding your assessment of a 38Mbps maximum-I'll stand by it. Your assumption of my comment was that there was more available when in fact there is less. Most cable companies while using DOCSIS 2.0 compliant modems are still running a DOCSIS 1.0/1.1 network. Maximum downstream bandwidth in 90% of the nodes would be 27Mbps/30Mbps. Only on a DOCSIS 2.0 platform will you attain 38 Mbps. Hope that clarifies my earlier response and my apologies for the terse post. I can be quite long winded when minus 3 children on my lap.
No sir you are wrong, 256QAM downstreams that deliver 38Mbps have been available and a required part of equipment conforming to the standard from DOCSIS 1.0, DOCSIS 2.0 gives enchancements to upstream bandwidths, not down.

Your belief that DOCSIS 1.1 gives more downstream bandwidth than DOCSIS 1.0 is also incorrect. The main differences between them are security (baseline privacy plus), the *requirement* to support 16QAM upstreams and dynamic service flow addition / modification / deletion and QoS for Packetcable-like services.]]> http://www.dslreports.com/forum/remark,15638187 Wed, 08 Mar 2006 02:46:44 EDT Re: 2 Shaw Docsis Modems on 1 cable outlet http://www.dslreports.com/forum/remark,15637415 perfectstorm : EuroDOCSIS is based on a 8MHz RF channel hence it's greater downstream capacity.

This would make nodes very asymettrical however it would explain the throttling on upstream traffic to an extent, throwing 76Mbps or more at a node downstream and only 20Mbps upstream while offering 7/1 or so will make ya do that...

Anyone who can show the multi-downstreams to be the case please do, I'm interested, especially as it's the only way to get over 38Mbps down each node.

EDIT: Unless you're in PAL land in which case we can stuff 51Mbps per downstream down a node. Have to love EuroDOCSIS.

Maybe there is a reason they told you that. If you're wanting to run 2 modems and pay for 2 internet accounts, then good for you. If you're needing it for 2 computers and you're ok with buying and running a router, then good for you.

Chances are, the first 4 guys were trying to help save you money, and the fifth wanted the commission for selling you a second internet account, if that is what you did.

Too lazy? Possible, but it takes 2 to 3 minutes to create the work order, get the modem serial, and post the work order off. Not too hard.

You be the judge.

The only differene between the coax cable in your house and the distribution cable is size, that's it.
As to the original question, the only thing you have to be concerned about is the amount of signal available at that one particular outlet. Remember when you split it your essentially cutting the signal by 3.5 db and you generally don't want much less than 0db hitting a modem or you could start running into issues. ]]> http://www.dslreports.com/forum/remark,15603709 Fri, 03 Mar 2006 12:31:36 EDT Re: 2 Shaw Docsis Modems on 1 cable outlet http://www.dslreports.com/forum/remark,15602876 perfectstorm :
