I suspect that James was referring to the ISDN signalling channel, which can be intercepted by wire tapping into the client copper line. This is not SS7.

The ones I have experience with are the Adtran Atlas and Newbridge 3600 Mainstreet. http://portal.adtran.com/web/page/portal/Adtran/group/42 http://www.datacomproducts.com/pdf_files/MainstreetProducts/ms3645.pdf -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
