[Asterisk-Users] some EICON Diva 4BRI questions

[Klaus Darilion]

Hi Armin!

Thanks for the detailed answers and isdn for Linux basics.  I will take
the opportunity to ask some more questions :-)

Why do I need a cable with 100Ohm termination? Shouldn't be the
termination inside the DIVA Server? Until now (with quadbri and other isdn
card) I only used CAT5 cables with BRI-crossover PIN layout. No resistors.
Can you please explain this a little bit more or give me links to the
wiring basics?

This means all kind of B-channel data (human voice, modem, fax, data ...)
can be handled in pass-through also with the V-4BRI card?

On the Eicon homepage I find to source packages: version 7.7 (they call
ist stable) and version 8.0 (they call it beta). To which one of these do
you refer with "v3"? Or is there another version somewhere hidden on the
homepage?

What is meant with "newer firmware"? Is there a new firmware available
which must be flashed into the cards?

Is the new v3 ready to use in production environment?

thanks
