Springfield, IL | Something interesting I was routed through elmhurst at my old house and according to beach boy, people who live in the area around me that have service based out of RT's are through the chicago redback because it is considered SBCIS, instead of ASI....Wierd eh?

It's still confusing, just the way the redbacks and how people are routed. Wouldn't it make sense to put someone on a redback to where they are closest at?

C.O. based DSLAM's are DS3 sized pipes that traverse across the ATM cloud, and eventually will aggregate with other DS3 connections to an OC3 port that feeds a particular RedBack at ASI.
The RT's, being field based, are Telco owned and operated. The circuits will eventually terminate on an ASI RedBack, but must first traverse the Telco network. This includes originally terminating on an OCD device, which concentrates the circuits of several individual RT's, then terminates as 1 logical pipe to the OC3 port of the ASI RedBack.
If the ASI RedBack has say 10 pvc's terminating on it's OC3 ingress port, 7 may be individual DSLAM pvc's, and the 3 remaining may be Telco RT pvc's, which in turn may conatain several RT circuits within each connection.
Where ASI sends the traffic to SBCIS, or any other ISP, from that point depends on customer density, aggregated pvc count on the ISP end, proper traffic balancing, or any number of other factors. Once in the ATM cloud, the distance between the Chicago POP or the Elmhurst POP, and any RedBack router within the respective POP's, is irrelevant.
Remember the RBAK you see in your trace route is the ISP RBAK, not the ASI RBAK. This is because it is the first point at which you are at Layer3. Look to your Enternet300 properties( or whatever PPPOE client you are using), and you will see another RedBack name - that is actually the ASI RedBack...the PPPOE server.

That's the single best behind the scenes looks I've seen. That picture should be in a FAQ or something. I don't think it even needs "sprucing up" a little description of the encoding at various points would be a help. I think everyone understands ATM, but L2TP and the encoding between the home could use a little more explanation. |

Thanks for the visual core network! That is similar to the way I had imagined it was designed. Nice and clean so that ASI can handoff the ATM PVC's to any provider anywhere who plugs into their ATM backbone.

Excellent stuff core network 
A better pic would be awesome if you have the time 
The PPPoE... I was thinking that was used between the computer and modem...and from the modem on it was ATM???

It is ATM from the modem to the DSLAM, but the authentication and control, which is PPPoE, is encapsulated within the ATM cells.
What further would you like to see. I'll detail as much as I can within the rules of SBC disclosure. |

This info is good to have "as is"
Thanks for posting!!!

| Good Idea,
Now that it's my wallpaper I don't have to look for it later when I have more time. |
