As regular readers know, I regard the upgrade of the phone system (aka the “public switched telephone network” or “PSTN”) to an all-IP based network as a majorly huge deal. As I’ve explained at length before, this is a huge deal because of a bunch of decisions the Federal Communications Commission (FCC) has made over the years that have fragmented our various policies and regulations about phones into a crazy-quilt of different rules tied sometimes to the technology (IP v. traditional phone (TDM)) and sometimes to the actual medium of transmission (copper v. fiber v. cable v. wireless). This whacky set of FCC decisions has produced a great deal of confusion about what we are talking about when we talk about the upgrade of the phone network.
As a result, people keep pointing out the same two things to me over and over and over. “AT&T is not switching to fiber to the home! Their upgrade is still copper!” The other is: “Verizon is pulling up all their copper in New York City (and everywhere else in the Sandy zone) and shifting customers from copper to FIOS without getting any permission from anyone!” These observations are usually made with the same fervor as Charlton Heston giving out his recipe for Soylent Green.
Allow me to debunk the Cult of the Copper Snake (with bonus points for recognizing the Biblical reference. And no, it isn’t the Golden Calf. It’s the Copper Snake.) You can have an all IP network that runs on copper, and you can run a traditional TDM-based network over fiber that is treated like a phone service. Both of these are different from a TDM-system that runs on copper. All three are treated differently from each other from a regulatory perspective. I also must point out, in AT&T’s defense, that AT&T never claimed it was upgrading to fiber, and in fact has been quite specific that they are not going FttH (to Wall St.’s great relief and the disappointment of many others paying attention).
If you want to stop here, you can. If you want to find out why this is true, and why people keep confusing them, then you must continue on, delving into the minutiae of the last ten years of regulatory history. While a pain in the patootie to sort through (and I will do what I can to make it less boring where possible), it’s worth it if you want to understand what’s going on and how AT&T can be going on about how this is going to improve broadband and blah blah blah without ever promising to move to fiber to the home.
