Hi, All Please forgive me if this posting should be in another newsgroup.
I am reading about the ITU V.32 and V.34 recommendations. While I have been able to find descriptions of the signal constellations and coding schemes, I have had a tough time finding out information on the communications protocol. Specifically, I want to know how the calling and answering modem keep the dial-up connection alive when neither party has any data to communicate.
If anyone has any info on this (or knows which forum would be a better fit than .design), please let me know.
Thanks.
