- Hmmm... well, after weeks of debate of whether one can turn an E into an E+
- I have this to say:
-
- 1- OK, it may or may not be possible to "upgrade" an E into an E+ through
- various hardware "fixes" etc.. but from what I've heard on the net and
- by looking inside my E, it seems to me that the two TMS320C25's do most
- of the work... One SHOULD be able to do CELP and maybe a non-optimal
- 19.2 and maybe even a few more "E+" functions on the "E" model. If you
- need more memory, the memory board is "piggyback" so you can replace it.
- All that really needs to be done is to program some EPROMs to do these
- things.. which leads me to my second point:
-
- 2- (I'm not accusing anybody here, least of all Tyrone- he HAS been extremely
- helpful and attentive to the questions of all of us net-people- BUT), his
- remark that "There is no way possible that you can turn the E into an E+"
- just sounds a lot like something the marketing droids would say- "NO,
- you can't do that with the normal model, you have to spend another $$$$$
- and get the "enhanced" model instead". I looked at quite a few modems
- before I bought my 1496E and while I'm happy with my choice, words like
- this tend to make me lose all respect for the company. When you say
- there is no way that we can "upgrade" the product, are you really saying:
- "Yes, we could offer an upgrade, but its too much bother for us and
- marketing/management wouldn't approve because they want you to spend
- more $$$ on the "enhanced" product rather than less $$ on an upgrade"?????
-
- 3- OK, if its too much bother for you, how about you let some of us, your
- customers do it? Many of us are more than qualified, and many would
- probably be willing (including myself) to sign a non-disclosure agreement
- or whatever in order to gain access to documentation on the innards of
- the modem (- which brings up again the issue of a "Developer's Kit")
-
- So, in summary: Is it REALLY not possible to upgrade (or at least add some of
- the E+ features onto the E)? Or is it just economics/marketing? From looking
- at the innards of the modems, it seems to me that even if its not possible to
- upgrade, one SHOULD be able to add some E+ features to an E modem. If a
- "developer's kit" is made available, someone out here in netland could
- probably do this job and save you a whole lot of time and money (you could
- sell the developer's kit with an upgraded DSP memory piggyback board, and
- then once someone has written code for whatever feature, you could package
- EPROMS with DSP boards and sell those as upgrades... possibilities are
- endless..)
-
- Oh well.. I've had my say- I hope somebody takes the time to listen and maybe
- act on some of my suggestions..
