VDSL on the loop and why it didn't happen. It is simple, as most things are. The complications are built in by the special interest groups, the lobbyists etc, in short the collusions we discussed yesterday, ad nauseam. Primary Cable replaced by OF. You pull fiber in along the primary cable ducts all the way to the PCP ( the box that your terminate your primary cable and crossconnect it to the secondary cable. So the first part of the cable plant would have been OF. Then the last 300m or so, the secondary cable, you leave them as copper an would have run VDSL at 25 Mbit/s which is half of 51 Mbit/s which on third of a STM1 in SONET SDH. Very very simple. The day would have come where we would pull out the secondary cable and would go OF all the way to the building or desktop. It doesn't need a genius to think this. Whoever thought it over should have paid royalties to HFC networks. OF to the neighborhood and then coax all the way to the TV and Cable Modem that I am touching with my feet right now under my table. But that was supposed to be executed by the scavengers cum predator a.k.a ILECs. I don't know, but perhaps SBC supported one of these golf tournaments and between a Jack Daniels and another, the guys thought they would have to implement G.303 open the switch and they decided that it wasn't that good and killed right there. So the C.O will die out when in about 5 years it will be technically obsolete but it will die closed.

Why a network that would had implemented ADSL must have opened the switch. Well you would run T1's or E1's from the switch all the way to that box in the neighborhood. You would be running a 0.3-3.4 kHz analog pair of wires. But an open interface to the switch would have meant a Taiwanese company making the stuff and putting out of this business LU, NT, NEC, SI, Ericy and ALA. So they installed base of switches were at the mercy of the Asian suppliers. So they thought it was better to keep selling analog subscribers' cards to be installed in the switches that they "own" and keep the Taiwanese out of this sweet deal. They did this together with the US WEST's of this world that were more interested in selling a second line so that you would use your dial up for the internet and could still make phone calls. Everybody was happy. That's why I told ADSL is dead. Because I know damn well how those things are made. If anyone dispute this, I would gladly change my mind if persuaded.

Why you could not open the switch: A telephone switch is an accountancy trick the cost is split 80% SW and 20% HW. This because the bean counters put SW as operations expenses and HW as capital expenses. If you had open the switch, you would have SW going from the switch to the network element. So if the Taiwanese would have sold the stuff -since the interface was open- the money would have gone to the Taiwanese and not to the switch makers. And that's why the swicth will die out closed.
