 http://broadband.motorola.com/consumers/support/default.asp?supportSection=DiscontinuedProducts> Interesting point about the underlying encoding or delivery technology driving what "modems" will continue to work on a given ISP. Same could maybe be said for DSL at some point. But all the smart folks hang out here - and we learn so much together :) | |||||||||||||

Please log in for more thread options That's already happening with AT&T DSL. The new and improved setup script tends to only work on DSL modems that have the PPPoE login and password stored in the DSL modem or in the computah, but not where it's stored in an "unsupported" router. I ranted on the topic recently in ba.internet. Short version... some older Speedstream/Siemens 5100 modems don't quite work for initial setup or reconfiguration. <https://pbells.broadjump.com/registration> Fortunately, I have a partially tested workaround. If you want to try the above URL, be sure to have the computah audio turned on for the full multimedia installation experience. There are also issues with ancient DSL modems such as the Alcatel 1000. There's no way for the DSLAM to query this modem for statistics and quality info. Same problem when the ISP uses AT&T line tools. These modems are justifiably banned. Legacy modems are a more serious problem in cable modems. With DSL, there's no real security in the transport system. DSL has a dedicated line to the DSLAM at the CO. Short of wiretap protection, there's no security needed. However, cable is mostly a bus or ring topology, where everyone is on shared connections. Security is paramount and is imbedded in the modem with BPI+. The modem also needs to be remotely managed. This is available for DSL modems with SNMP, but the various DSL ISP's seem reluctant to use it. In general, when there's an upgrade to the cable service, there's also an upgrade to the privacy and management features, making maintaining legacy modems a problem. I'm not very smart. However, I'm very sneaky and sometimes evil. I'm also into Learn By Destroying. -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 | |||||||||||||
