asterisk users - Sep 2004 - Multiple MD 3200 (Intel 537) cards on a single system.

Has anyone been able to sucessfully use 2-4 X101P clones with Asterisk on a 
single system ?

I'm using one Encore MD 3200 modem sucessfully, alongside a TDM400P (3 FXS,
1
FXO) and would like to be able to use up to 4 X101P on a single system. In 
most cases I'll have 2 or 3 instead.

I understand all the issues with interrupt sharing and PC motherboard quality. 
Just need to know if any one was sucessfull with that.

I would love to use a TDM400P, but in order to import one, here in Brasil 
we're hit with 150% total import taxes for this kind of equipment (getting 
the final price to over US$ 700), while we can purchase Encore modems at US$ 
15 after all taxes, so it's kind of hard to use digium cards here.

I have used four X100P clones in a PIII with Intel motherboard. It
worked fine. Also I had it with an ASRock mobo and Athlon processor,
it worked, but not so great.  I had allways one card sharing an
interrupt. There were sometimes artifacts in the sound, faxes did not
work, and data calls: forget it.

I'm running four now on a Powermac 9600, I'm planning to add another
one in the next few days. It works perfect. I can fax, I can make
modem calls. Life is good.

Get yourself an old PowerMac from the junk yard. Asterisk and Zaptel
works perfectly on those with LinuxPPC, for example Yellow Dog Linux.
There are no interrupt issues on Macs.

The pre-G3 PowerMac 9xxx series all have PCI bus and some of them have
a PCI based VGA in a sixth slot, so you could remove that and run six
X10nP in a single machine. The PM 9xxx series are vintage 1996-1998,
they're too old to support MacOSX and therefore they are available
second hand at real bargain prices. The going price at a typical
second hand store here in Tokyo is 50 USD with 90 days warranty for
such a machine. In some other places you may pay as much as 200 USD -
still a bargain.
