said by wilburyan  :There is one problem with your "Jitter" idea... how do you target Skype specificly? What if the provider is delivering there own VOIP or multimedia service through the same connection? Comcast, Charter, others??, don't use std VOIP like Skype or Vonage does. They actually use a separate RF frequency on the cable(one not shared with the cable modem) to provide voice services. So their voice services don't share that std data internet channel. They use a private, separate path until they hand a voice call off to the POTS provider at a gateway. Therefore, anything they do to the data channel won't affect their voice services.

| Wrong, wrong and wrong. More lies and FUD from the corporate drone.
Packetcable 1.0 (and 1.5) specs use EXACTLY the same frequencies as regular IP traffic. In fact, when you make a voice call over your comcast phone, you are giving up some of your bandwidth to make that call. It's hard to see downstream, but VERY easy to prove upstream. Start an FTP upload to a site, let the speed stabilize. Then make a comcast call. BOOM, you've lost about 7KB/sec transfer speed while the call is in progress.
Lie #2: The cable modem itself, being docsis compliant, uses EXACTLY the same pathway to the CMTS. If your CMTS is overwhelmed, or sucks, your digital voice will suck too. However, they have the OPTION to offload the traffic destined for the POTS network, by creating a separate Voice Path to the Media Gateway. Now we all know that comcrap isn't going to run a separate circuit to each CMTS just to give their voice a clean path, so they grab some channels from the uBRxxxx at the CMTS, and take it AWAY from your paid for bandwidth. This is a mini 2nd tier network, which they work very hard to keep quiet. It's EXACTLY the same thing they want to do with the 2nd tier for ANY traffic they can extort from providers. Pull off some channels, and give it a dedicated pathway, without actually 'building' a better internet to provide 'better' service. Steal from the poor, to pay to the rich, that's their motto.
Asking Retire Rich to explain a TECHNICAL answer to corporate extortion is like asking a fish how to ride a bike.

| In charter areas, we use an entire diffrent channel (frequency). Granted, it could be done in the same channel as voice, but the design was to use an entire diffrent channel.
Also, in most, but not all Charter Markets, an entire diffrent CMTS is used for voice. In east TN, we are using seperate CMTS's and seperate channels. | |
