Note that Catena's approach doesn't provide a place for voice over DSL. Catena executives I spoke with this week at the ComNet trade show think users want to keep their regular phone lines and get DSL for data, not a bad way to look at it especially since VoDSL right now loses some key lifeline functions. But you can probably see some other limitations of the initial Catena offering: It only provides ADSL, and it only works in communities where a telco once installed a digital loop carrier system from Lucent (or AT&T in olden days).
But don't worry, this start-up with $105 million of funding iis more ambitious than that. Which brings us back to that roadmap, which envisions a complete overhaul of the old digital loop carrier architecture with a fully packetized, voice/data approach Catena calls "broadband loop carrier." That'll be the subject of another newsletter, so stay tuned. Or for a sneak peak, head to Catena's Web site at www.catena.com.
