[Asterisk-Users] Multiple ISDN BRI Units with Asterisk using Bristuff zaphfc in NT mode?

2005-07-16 Thread Carl Andersson
Maybe this is rather a hardware question, but I am posting it on this 
list because the probability of someone else of you having tried this is 
greater here than other places I can think of.


I have an ISDN card that is setup in NT mode using the zaphfc driver in 
bristuff, and I got it working perfectly with one ISDN phone using a 
crossover cable and 100 ohm termination at the end of the cable.


However, if I connect one more ISDN device to the ISDN bus both devices 
stop working, so the question is:


Is it only possible to use one device with a HFC card in NT mode or is 
there something else I need to do first to make it work with two devices?

Hi Carl,
I just started yesterday afternoon with exactly the same setup so you 
are a bit ahead of me.
If anyone answers you directly then please be kind enough to forward 
their comments to me.


I have not even tried to sort out trunks, bristuff or anything yet but 
it might be worth pointing out that my initial problems were that, using 
an old pIII motherboard with pci graphics, network plus 2 HFC bri isdn 
cards, I ran out of IRQs. I had to lock down  exclude the irq for the 
network card before the 2 ISDN cards woke up. I now have the network  1 
ISDN card on their own IRQ and the graphics and 2nd ISDN card sharing an 
IRQ.


Maybe this could be a similar problem for you?

I'm  using this HW with AAH 1.1

Keep in touch,

Cheers,
Zoltan
