North York, ON | Re: 2 Shaw Docsis Modems on 1 cable outlet that would be literally impossible. you would need to connect an outlet to a modem. you would need 2 outlets to connect 2 modems. | |

1 edit | Re: 2 Shaw Docsis Modems on 1 cable outlet said by RagingTurkey  :Two modems cannot communicate with the same node on the same wire at the same time, or so I've been led to believe. Of course they can, while actually they can't but the Time divisions, hence A-TDMA(advanced time division muliple access technology), allows several modems to communicate simultaneoulsy on the same wire and the same RF channel...or so it seems. | |

| Re: 2 Shaw Docsis Modems on 1 cable outlet Hundreds of modems communicate on the same distribution line all the time, if they couldn't there would have to be a different coax line for every single house to the node!! 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. | |

| Re: 2 Shaw Docsis Modems on 1 cable outlet Right.
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.

@204.209.x.x | This is %100 possible. As long as the RF is good enough you can run a ton of modems. | |

| That picture actually came from a local lan we put in Calgary,Alberta called Lanageddon. So yes it is possible as the previous users posted above. The box pictured there was running linux at the time, but we currently use an openbsd box now that works much better. The connection works great and is very fast. I will post a picture of the current setup once we finish the event(which is running right now). | |

| 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. | |

It's all internal network, no need for 11 modems. | |

| 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. | |

| 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. | |

| 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. | |
