AT&T Migrating Phone Network to IP

Posted by CowboyNeal on from the keeping-up-with-the-jones dept.

prostoalex writes "Following the lead of Sprint and Telus, who are moving their telephone networks to IP, AT&T will spend $3 billion to migrate to an IP-based network. By the end of 2005 about 270 legacy systems will be retired." The article also notes how the current ratio of packet traffic to voice is already 8:1.

    The problem with POTS systems is that you have to have the entire country wired with copper. A place that doesn't have the same huge investment in infrastructure that the US has is probably better off buying a used cell phone system and just running fiber between the towers. We may think of cell phones as being a luxury but that's only because we have 70 years of investment into copper to every home.

    you didn't live through networking 'revolutions' like ATM. at that time we were told repeatedly that IP may have been a nice playground, but the telcos, who really know how to run a service, were going to take over now. IP and TCP were never going to be suitable for large scale business deployment.

    'at&t moves voice service to ip' would have been a hilarious gag article 10 years ago, now no one even blinks.
