I am guessing it is not 2-way because of its type and information given on the BeoWorld site: http://www.beoworld.org/prod_details.asp?pid=393
It also writes that 2616 is definitely 2-way, like you said AT.
That's too bad, I don't have the proper type for what I want to do. Sometimes you have to update your system if you want to use "advanced" options...
Thanks.
