Typically G4-machines include hardware and software for interworking with G3. This will remain true for many years to support the huge installed number of G3-machines. Technically this is done by a G3-modem and a codec for PCM<->analog conversion, and some software, of course ;-) Some countries even require a G4-machine to be G3-compatible to get the PTT-approval. -- oeschi@netmbx.UUCP | Johann Deutinger voice +49 30 396 50 21 | Ferrari electronic GmbH (.. no, we don't sell cars) fax +49 30 396 80 20 | Beusselstr. 27 - 1000 Berlin 21 - FRG
