Two Questions: I am looking for a compendium of PTT impedances for various countries. The specific countries I am interested in are: Australia, China, Hong Kong, Indonesia, India, Korea, Malaysia, Phillipines, Thailand, Taiwan. What is available?
I have also heard that the impedance may be different based on whether you have a voice connection or a data connection (modem). Can anyone confirm or refute this? RCIC - http://www.rcic.com Regulatory Compliance Information Center
