Hello you out there in the world !

I really need help about the implementation of CELP used in Zyxel
modems. The only thing I know about it is that there are two TMS320C25
built in running at 40.16 MHz, and the "output data rate" is 9600 bps...
(not 4800 as in USFS 1016).
I want to write a program that is able to convert the CELP coded data
into an 8-bit linear (not mu-law or something like that !) representation
of the signal and vice versa (no, must not be realtime)...
Anybody who can help me ? Many people here are interested in this.

Thanks in advance - Kolja

(I'm also reachable in FidoNet as 2:241/2101.27, per snail mail via
 "Kolja Waschk, Oevelgoenne 23, W-2000 Hamburg 52, Germany" and last
but not least by a normal voice phone call : +49 -40 8804056 !)
