This dialog between wiredog and Michael Allard is painful. Allard is not only correct, with each attempt to prove himself right by describing the details of installing a set-top box (which appears to be his job), Wiredog is proving that he knows very little of the moving pieces of the entire process of connecting or termination of on net and off-net calls.
Beyond this, Mr. Allard is exceptionally accomplished and familiar in ways that few of here could begin to imagine with all the components of these networks and this technology.
Only his polite demeanor and self confidence have prevented him from embarrassing this other person in ways that were it I, would be so humbling and humiliating that I would probably leave the board.
Wiredog, please, for your sake, just stop. Describing in minutia the process of plugging things into a set top box that might channelize the various signals or IP traffic until it reaches the edge of Comcast's core network is irrelevant. Unless the call is going ONLY to another Comcast customer, and thus can stay channelized it HAS to go either to twisted pair or to the Internet. In the second case, if there is no QOS the call quality would be very poor.
I asked you earlier about this and you gave the same erroneous answer. Your three day classes clearly covered only how to set up Ms. Jones. it didn't cover network engineering or peering and you obviously haven't graduated to that level so do us all a favor and stick with what you know.
