VN4 is Version Number 4, and ETSI is the European standards-adopting organization for telecoms. So you might want to check for "E1 support" (ISDN in Europe, basically) if you want to connect a PRI-capable equipment - I assume that's what you are looking for since you mentioned the TE220. If you read French, you might want to look at this page also: http://blog.nicolargo.com/2008/01/installation-dune-carte-digium-avec-asterisk.html I found it very useful when I installed recently a TE220 card. Good luck, Laurent -------------- next part -------------- -- Laurent Steffan Consultant VOIP Web: http://VOIP.nc
