Re: [Asterisk-Users] DS3000P - 20 E1 capacity on single card
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.

And with a latency-sensitive product like voice, bus contention is not something you want to add to! :) 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 am not in position to reveal the company name at this stage unless MN wants to speak up :) 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... -A. ___ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

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. -A. ___ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

like it says, the equivalent of 20 E1's or 28 T1's and I guess you know how many channels a E1 or T1 PRI is On Sat, 9 Apr 2005, izo wrote: I just checked digium's site.
