Re: [HSI] 2 modems? Most likely the CMAC is the cable MAC ID.
EMAC would be the Ethernet MAC ID if it was being used for dual purpose.
MTA MAC is the connection that receives the IP address in the phone modem. The Multimedia Terminal Adapter (MTA).
As far as the bandwidth they are provisioned for, it is 384/128. It runs on a separate network within Charter, so it won't be visible to a cable modem- or at least it shouldn't be. |

Example, you run P2P, clients are eating up your upload. There goes chopping VOIP. I can see the logic in all. It's just another 7db on the splitter and creating more signal noise on the line. Look at this way that 2 modems for every customer who has internet/voip. Wouldn't what be more overhead on the UBR? -- Star Fleet HDQ / SFO - Admiral Ross »www.stb575.com |

| You make good points with the extra equipment when the technology is most certainly here to utilize one modem to handle both duties. Separating the VOIP and HSI through QOS techniques. Yes adding any other device is going to add a bit more attenuation to your signal if you don't happen to already have an extra port on your current setup.
Though, generally, if your signals are good at the time of implementation it shouldn't have a negative effect on the other devices you utilize. If you are already borderline in areas, I can see the potential concern.
As for overhead on the Universal Broadband Router -- The Telephony is operating on a separate network, and this is pure guess work -- But I would imagine that several configurations can exist among that network.
Possibly utilizing another uBR for the telephony portion of the network, as not to create overload for a pre-designed uBR for HSI. Or, which I believe is more common, to upgrade the existing uBR to handle the load of both Telephony and HSI Data.
Also, with packet techniques, I have *heard* VOIP traffic gets priority over your standard HSI.
Though, I don't believe there is a unanimous standard across the board for all KMA's .. It is probably more of a case by case basis, and how the markets load currently is.
In regards to chopping VOIP -- that is , partially, the reason for the secondary device. I would imagine with a data device dedicated soley to your Telephony,.. it would not only be easier to provision and keep track of in the databases of the MSO.. but also being on a separate network path, not be effected by the local CPE, such as your HSI CM. IE: P2P load, cutting into your bandwidth for Telephony. That Telephony bandwidth remains untouched regardless of how much you max your Cable modem for HSI.
I'm not sure if you were insinuating that the splitter itself was preventing the two to interact but the splitter is just a means to create another path for the new device to receive and send data on. It does not change the dynamics of traffic flow. (I am not saying this is what you meant for sure, just clarifying in case).
Again, I don't think the MSO intends for the Customer to monitor the traffic/signals etc of the Telephony system.. But with a bit of determination, that you have, I wouldn't put it past you to figure out how to tap into the "read-only" data.  -- Life is not a problem to be solved, but a reality to be experienced. |

 rloconeHonor Our Heros, Our Armed ForcesPremium join:2002-04-10 Kokomo, IN | thanks for clearing some things up. As you point out read only data. I have no wish to manipulate the data just monitor it. I'm aware that the EQUIPMENT belongs to Charter unless I purchase my own. However, their EQUIPMENT is encompassed in MY network. So, I feel I have the right to be able to monitor it. If an when I get around to it, I'll setup a system to let me know when it goes down and recovers(Alerts, Port triggers, IDS, IPS) If any service or device fails 3 consecutive times an admin alert is generated to my cell phone. This stands for servers, workstation and routers.
I'm already working on installing a Network tap and integrate it into my network. The tap will be used to monitor downstream/upstream within the confines of my network.

 stivvyTechnonerd join:2002-05-08 | Actually the equipment exists on CHarter's network. It does not interact with your network in any way, shape or form. The ARRIS modem reports to a completely different UBR and does not have a public IP address. Instead it has a network address that exists solely on Charter's network.
There is no activity that you should be able to monitor. It has no connection to the Internet, only to Charter's network.
Integrating it into your network may cause issues with both sides of the operation, especially if you end up bridging two networks that are meant, by design, to remain separate. In fact you may even open yourself up to more of a security risk by doing what you propose.
The only thing that Charter's EQUIPMENT does is take up space in your home. It never touches, nor ist it meant to, touch YOUR network- unless you make it do that, of course. |
|
 rloconeHonor Our Heros, Our Armed ForcesPremium join:2002-04-10 Kokomo, IN | Maybe you misunderstood me. The tap was to be integrated into my network my own equipment which lays on the LAN side not the WAN side. So the Arris would have like a 10.xxx. My ultimate goal is to learn how all of these devices/services work and interact. Being an educated consumer is a better consumer. |

How exactly is this on your network? Is it connected using ethernet? Because if you are speking of it as being connected to your network simply because they sharer a coax connection on a cable tv line then that is an incorrect assumption.

Does Charter Telephone service work the same way as traditional phone service? Inside the customers home, the only difference is that Charter Telephone does not work with rotary phones. Outside the customers home, we take advantage of state-of-the-art broadband technology and, in most areas, Voice over Internet Protocol (VoIP) technology. This allows us to deliver crystal-clear calls and advanced calling features.
« Back to Top
Are Charter Telephone calls routed across the Internet? No. Charter keeps the calls on our private broadband network until our switch delivers the call on the PSTN (public switched telephone network). Calls are just as secure with Charter as with any other telephone provider. |

 rloconeHonor Our Heros, Our Armed ForcesPremium join:2002-04-10 Kokomo, IN | I see it this way the EQUIPMENT is generating traffic that comes into to my network (HSI). Traffic is also generated inside my network and leaves over the WAN. I feel I'm responsible for any and all traffic that is WITH the boundaries of my network. As most of you pointed out the VOIP doesn't cross into my network. I can live with that.
Here is an example. If you run and share WIFI in your neighborhood and all of your buddies are sharing off the connection from you. Later a stranger parks his car on the side of the road and uses your connection. This dude downloads child porn, does a lil hacking, steals credit card numbers. The courts will hold you responsible for this "dude's" actions. Why? Because it happened within the confines of your network.
Also, I want to know what my step son is up too. There are way too many sexual predators out there looking for innocent kids to pray upon. I don't want my son to be a statistic. Also, my fiance always have family over and company. The PUBLIC computer is in the living room. I need to know who and why and what they are doing.
With WIFI becoming more and more popular everyone is getting one. Many people leave the defaults on. No such security there. Wardriving is another area of increased activity. So setting up IDS, IPS, SPI all work in your favor. -- Star Fleet HDQ / SFO - Admiral Ross »www.stb575.com |
