Re: Please explain why CG is a static solution and what this means? NYBB, CG is a non-programable ASIC. As far as I know it has one port. You can't upgrade without replacing the chip, and using it in a DSLAM is inefficient with one port. Good for the Consumer Modem that will require a hardware upgrade. Vs a TI C6X which will have multiple ports initially, and more in future versions, and is software upgradeable. The more ports on a chip, the more ports a DSLAM cabinet can handle without increased heat. A primary design goal for Company Office Equipment. JW@KSC

[MOT's 'static' solution] << Please explain why CG is a static solution and what this means? >> as i understand it: CopperGold is a hardwired embodiment of a snapshot of AMTX's DMT ADSL, circa 1995. the algorithms are implemented in silicon. Improvements in AMTX's algorithms since '95 are not reflected in the chips. to add features, change algorithms, or fix bugs, MOT would have to go back and design a new chip and possibly re-license DMT from AMTX. think of it as an Intel processor with Windows 95 hardwired in silicon. If Microsoft added a new feature, Intel would have to design a new chip. The TXN C6x DSP is a general-purpose processor: it's software programmable and can perform a wide range of tasks. AMTX ADSL is implemented on the C6x as software which is executed on the fly by the DSP. it's easier to write software than to design hardwired chips, and that you can correct, improve, and extend the software without changing the chip. This is like how PCs are today: a general-purpose CPU (Intel) running upgradable software (Windows). A Windows update or patch doesn't require Intel to design a new CPU. mark
