True enough, but you still need to marshall the data going between PCI busses

do add to the fun of getting a low latency VOIP system together.

Absolutely. The DS3000P will definitely support PCI-X, and probably bus 
speeds of 100MHz or higher, so at least if your system has that you will 
have plenty of bus capacity. Many servers nowadays actually have their 
NICs on a separate PCI bus as well, so the TDM and NIC cards won't be 
contending for the same resources.

Very true; realistically, modern PC hardware has more than enough 
bandwidth to do what is required. The real issue is timing, based on 
contention for resources, and how that impacts latency. The existing 
boxes out there (not PCs) that handle DS3 have far lower performance 
metrics than a 3GHz P4 or similar system :-)

Well yes, but they're not a general computing platform either and their I/O

It means something to me. 

Kevin

I am far from needing one of these yet but I am interested in them. I
think that clearing up who does the transcoding would help some
people. I wonder if someone will use this for large scale network
needs. Image Stream is just down the Highway from me and I know that
they are using ~1 gigahertz processors on their T3 routing systems
with multiple NICs.

What would be a real example of use. EG: A Tyan Transport TX46 and
this card could handle what ever you could put on it. What is the
realistic low end of system that could support this card.

 It only 'doubles the bandwidth required' when compared to a single-board 

 solution, which does not exist.

My statement was not meant as a criticism:  only a description as to the 
difference beween putting the coprocessor on the DS3 board versus putting 
it on the PCI bus.  As someone who has no need for a DS3 board, I am not 
familiar with whether there is a card that does everything on a single 
board.  I was just describing the difference in response to a question.

 When compared to doing the transcoding 
 and echo can in the host CPU, it would be a major win :-)

Ah, the magic of DSP's!  :)  There's no question that you would be 
challenged to do a DS3-worth of transcoding and echo cancelling with a 
general-purpose CPU (or even several).

 Also, keep in mind that a DS3 is _only_ 45 megabits per second. Any PCI 
 bus (even lowly 33MHz 32-bit PCI) can easily handle 90 megabits per 
 second of traffic. People looking a DS3 cards are also likely to deploy 
 them in servers with multiple independent PCI buses, which would then 
 allow for even more bandwidth.

There is no question about this.  Base PCI can handle a theoretical 
maximum of 132MB (That's *bytes*) per second.  A DS3 with separate 
co-processor board is a tiny part of that:  about equivilent to that of a 
100Mbit Ethernet controller.  Old hat.  The only issue is latency.  Either 
you transfer information in big chunks efficiently, or small pieces 
inefficiently.  Given that there will be at least three devices 
participating on the bus (the CPU, the DS3 card and that theoretical 
co-processor), that means bus contention.  If you're talking 33MHz 32-bit 
PCI (which, from the picture, seems to be what we're talking about here), 
you may run into problems when you add in the Ethernet controller, disk 
controller, etc.

Of course, high-end hardware makes this less of an issue:  if you can 
dedicate a PCI bus to the two cards, then go crazy!  And if you actually 
*need* to manage 672 channels, you can afford a decent server with dual 
PCI busses!  :) 

 The mind boggles at the possibilities!

My mind boggles at the need for a DS3 in the first place.  I thought I was 
pretty cool the day I got my first T1!  :)  Some of us have to slum it for 
a living...  :)

That's not the point.  The point is that you have to transfer voice data 
twice:  once from the DS3 card to the co-processor, and once from there to 
the eventual destination (probably system RAM).  If the co-processor is 
integrated into the DS3 card that first transfer is handled and

That is correct; the DS3000P will support full access to every channel 
on the DS-3 (or E-3), however it is provisioned. In a T1-RBS signaling 
mode, that means 672 voice channels. In a T1-PRI signaling mode, it 
could be as many as 670 or as few as 644, depending on how many 
D-channels are provisioned.

The same logic applies to E-3 mode: since an E-3 is the equivalent of 16 
E-1, the channel capacity will vary from 496 to 480, depending on 
signaling mode.

Kevin,
Can you confirm if there will be some sort of DSP daughther card add on 
of some sort for the DS3000 so that we can run G729 transcoding?  I 
don't see how the DS3 interface would be usefull unless we could offload 
transcoding stuff to onboard DSPs.  Or is Digium only going to recommend 
this card for G711 only uses?

Thanks,

Oh god, you've got to be kidding if this is only for G711.
You'd have to have a 2nd DS3 worth of bandwidth to handle all those calls.

What about on board echo canceling? Software-based echo cancel on 670 would
put quite a load on any system.

G711 only; if you want transcode do that on a cluster of boxes feeding the box 
with this card in it.

Or wait another 10 generations of Pentium Processors to catch up with 
DS3 G729 requirements  :)

Come June/July an USB/PCI DSP cost effective solution should be available
to address this issues. It will transcode nearly all codec's.
I am not in position to reveal the company name
at this stage unless MN wants to speak up  :)

Put me on the mailing list for the PCI DSP card,  I'll beta test if you 
want.   Make the cPCI and you have yourself a product!

secondary card for DSP functions is very inefficient of the PCI bus.  I'd be 
curious to know if the Digium cards can even do PCI-PCI DMA.

And USB?  I would be *very* curious to see what these products can actually do 
to help.  There's a very good reason why any TDM boards that do off-CPU 
processing do it on the same card or over a separate bus...

 I have a TE405P and mine shows up as Xilinx but a lvl 2 tech a digium says
it still uses the TigerJet chipset. That's why it won't work in my Dell.

I'll paypal you US$100 if you can find a TJ320 chip on either the TE410P or 
TE405P.  It doesn't exist.

Now they MAY have incorporated the TJ320 chip logic in the Xilinx Spartan II 
FPGA but I would be **VERY** surprised if they did that.  Just my opinion, 
but I think that level 2 digium tech is full of shit.

I don't think they will; their quad T1/E1/J1 have no such POS on them.

Which specific Digium card does not use the TigerJet chip (as shown in

I sit corrected.  The 4-port T-1/E-1 cards do use the Xilinx.  The 
1-port cards and 4-port TDM cards do not.
