ITU-T / IEEE Standards FAQ
So, you have read the standards documents and the summary documents and the Calnex test guides but you still have questions...
The articles below might help. These are our answers to questions that we have been asked before. We will keep adding to this list as time goes on. If you still have a question that isn't answered here, then feel free to contact us at support@calnexsol.com. By the way, if your question is not strictly about the standards but more about how to test using Calnex equipment, you might want to take a look at our Product FAQ.
