I want to connect two ISDN bri card directly. Is it necessary to use a cross-cable? I use a fritz card in TE mode and a Atlantis Card (zaphfc) in NT mode. Thank's Matteo

If the pin layout of the ISDN cards is in TE mode on both cards, then you do need a crossover cable. Usually the cards are in TE pin layout, except some cards have onboard jumpers for changing the pin-layout to NT mode (like junghanns quadbri). I guess in your case you need a BRI crossover cable. attached is a picture of an ISDN BRI crossover cable (from Diva Server Adapters Installation Guide) regards klaus -------------- next part -------------- A non-text attachment was scrubbed...

Yes, I have read this part of the Diva Server Adapters Installation Guide and I think that it is necessary use a cross cable.
