Pigboy: You have some great questions! Taking one step back, the Westell DSLAM will support xDSL.
....SuperVision architecture is modular to support multiple interfaces and multiplexing functions, and has the capability to support CAP Rate Adaptive Digital Subscriber Line, DMT Rate Adaptive Digital Subscriber Line, HDSL line modules and fiber modules, giving network operators the flexibility to configure their SuperVision shelf according to their customers' needs and network service requirements. I'm guessing version 1 will support CAP RADSL only...
The Westell DSLAM will support the TI DMT line card, MOT DMT line card, Globespan CAP line card, HDSL 2B1Q line card and a fiber card.
The second paper from AMD talks about standard T1E1.4 DMT "256 tones". G.Lite/G.DMT "ex. 64 tones" will NOT use those higher frequency tones. The paper also talks about rate adapting in 32kbps increments, ie:
32Kbps * 256 tones = ~8Mbps for T1E1.4 or ADSL-heavy
32Kbps * 64 tones = ~2Mbps for one version of G.Lite
As you know the TI/AMTM solution is software based. If an RBOC wants to support G.Lite they download one algorithm that supports 64 tones. If the customer wants higher bandwidths the RBOC installs a POTS-splitter and downloads an algorithm that supports 256 tones. I remember AMTX was working on reduced power implementations in their DSLAM device which supported 1.5Mbps with extended ranges.
I'll assume the TI/AMTX solution will require less power with extended reach for their version of G.Lite:
...Lowering the maximum throughput will provide lowered processing requirements for algorithms, reduced analog sample rates, and reduced gate counts. These all provide opportunities for reduced complexity, higher degree of silicon integration, denser equipment configurations, and power savings....

Eventually.... but not in the near term.. until later. |
