From: Dick Shultz <[email protected]> Bernard,
The ITU recommendations make up the Q.400 series. Q.440 and Q.441 seem to have the best overview. They identify the protocol and tone frequescies as well. Once you understand the ITU recommendation I believe that you will need to cope with the national implementations to get the approvals.
