Hi,
I would like to find some way for hardware coding instead software
(using the Host CPU). Are there any PCI boards just with codecs (DSP)
or other way?

Heard good things about this card from some of my associates. quite
expensive though

A wild idea, why not use the graphics card GPU to do the compression? I
understand there're some work on using the GPU to do SIMD. Supposed to
be faster than the P4 an
Ouch. The 64-port Ai-Logix board goes for (!) $3559 USD. Who is
_paying_ for this stuff?!?
That's >5x multiplier on what I pay for Asterisk, including the $10
per channel G.729 license.
I will say that I'm looking for a good, dense DSP card that can be
bodged into Asterisk. I have a lin

Quite a lot of people. I know of at least 1 brand of voice logger that
use these boards for real-time compression. It was pretty much necessary
considering that some of those loggers were built on

I think you are way-over ambitious for a 1RU space. Heat, noise, all the
bad things computers do get worse in confined spaces. Perhaps Cray, or
someone will come out with a 1RU supercomputer soon. But I'd not hold my

In software, naturally. A physical DS0 needn't exist.

But even at that rate, that box is going to be mighty busy...
Why would you do something that crazy? You could put 8 high-end DSPs on a
half-height PCI card and have each one handle a DS2's worth of channels (up
to 96) and then have the 8th do general housekeeping of the entire DS3 and
PCI interf

My thoughts on a DS3 * box:
Forget PCI. Forget x86.
There are very good bsd and linux ports for the powerpc.
There are ppc's with very good TDM interfaces.
All these framers and dsps speak TDM. Very simple clean design.
If you do not want to build any hardware, you can probably find

You could always just do TDMoE to an x86 running *... I bet TDMoE would be a
LOT easier to port than all of *. :-)

If I recall correctly, * and zaptel compiles on the powerpc chip... no
porting needed.

There have been discussions here on this list already on the
availability of boards like SBEI's channelized DS-3 card (they've been
a reasonably approachable vendor.)
Do they make such a thing? The DS3 cards on their site appear to be HDLC
data only.
