This simple technical argument should make it clear: both the TERN and Com21 proprietary modems use their own customized MAC and PHY in the downstream channel which is hard coded into the modem ASICs of each company's products. Mark: (1) What does MAC stand for? Media access channel or something else? (2) Must the MAC (whatever it is) & PHY be hard-coded into the gates of the modem chipset? Isn't it possible today to rely upon non-volatile flash memory to soft-code the modems whereby it would be possible to "migrate" from proprietary to a DOCSIS protocol? If so, isn't it possible that TERN's modems (or any other manufacturer's for that matter) could take advantage of this type of reprogrammability to make that migration possible with today's proprietary protocols? TIA for your commments.
