Agreed. I was just pointing out what I saw. DSL is moving along with speeds and distances increase and prices becoming not only desirable but down right disruptive to t1 and T3 (see snip below). Cable rollout have been ramping up and most of my collegues that have cable access like it. Wireless does look very interesting (and out of favor with the street at this point) and even cell phone speeds could exceed 300 kbps in 2 to 3 years. Everything from MMDS to the home to some sort of LMDS, MMDS, Optic wireless mix that provides weather sensitive speeds for fixed wireless. I have to wonder if anyone trying to provide an access service that offers access to a combined say LMDS and IR P-MP networks as well as to fiber direct (or with GbE Copper hops) that offers subscribers a way to switch networks on the fly (hey it migh be possible in some larger buildings to offer clients the required transcievers, lan switches etc). Perhaps its a service with AirFiber and foggy day 56 kbs access. You mention FTTH and I have been reading a bit about PONs and the varies schemes (Quantum Bridge, TeraWave..). I believe there will be some interesting ways to provide optic speeds to the home user, but I am not sure which will have the cost advantage. Most of these designs are usefull in places where there is some but very limited access to fiber cable (and HFC I believe). I wonder how successful these rationing schemes will be vis a vis DMDM all the way. I believe LU was working on a dual fq laser approach that obviated the need for an end user to buy a transciever. And at least one company is playing with interleavers and "nonlinear interferometry" (I am still trying to quess at the physics here) to provide Fiber to the desk tops. So perhaps I'll keep my 56 kbps a will longer to see just which service is best for me (with a test of portablility from at 9.6 kbps access with a Jornada over a Motorala phone).
Netopia bonds DSL lines for faster connections

ALAMEDA, CALIF. - Netopia has an easier way for service providers to give DSL customers a fast link to the Internet and corporate intranets.
The company is introducing multilink PPP (MLPPP) support for its customer-site DSL routers, making it possible to turn up to four individual DSL lines into a single, logical connection.
The feature is available now for ISDN-based DSL (IDSL) connections, giving customers the ability to create a single 576K bit/sec link. A single IDSL line can handle 144K bit/sec.
This new capability makes it easier for ISPs and other carriers to deliver higher bandwidth DSL services to end users, says Harold Anthony, product marketing manager for Florida Digital, an Orlando-based ISP that has tested and plans to use the MLPPP feature to support new services.
Rather than calling for a DSL access multiplexer (DSLAM) that can bond two DSL lines together between the customer site and the carrier network, MLPPP bonds them at the customer site and any MLPPP-enabled router. For example, an ISP such as Florida Digital can install an MLPPP DSL router at a customer site, connect multiple DSL lines to it and bond them together at a Florida Digital point of presence. |
