I believe the chip is called "ProSLIC" See: http://www.google.com/search?hl=en&ie=UTF-8&q=site%3Alists.digium.com+proslic&btnG=Google+Search The TDM400P card is for ANALOG FXO and FXO lines. > Iʼve spent a frustrating day searching around and come up with > nothing.

As I understand it Digium cards are somewhere between a rock and a turnip when it comes to on board processing power. This is a Good Thing from the standpoint of cost. The smarter the card the more expensive the card will be. Smart telephony/DSP cards can run on very low end equipment. I seem to remember reports on the Asterisk-Dev mailing list about people running four T-1 lines into a 486 machine using Dialogic boards (just for IVR stuff, not using Asterisk). You could never do that with a Digium card. Dialogic boards are MUCH more expensive than Digiumc cards. It really comes down to this: Smart (expensive) DSP cards can be run on slow PCs. Dumb (cheap) DSP cards must be run on fast PCs. > Iʼm looking for a telephony card which does a reasonable amount of > processing on-board so that the PC isnʼt overstretched or interrupted > too often (it will be going in a Via EPIA system, which has one > physical PCI slot with a riser that has to accommodate a WLAN card > too, so it *has* to share an interrupt).

If you want a card that does a lot of processing onboard then don't look at Digium cards. However, most people do not need the card to do the processing on the card. -- Eric Wieling * BTEL Consulting * 504-899-1387 x2111 "In a related story, the IRS has recently ruled that the cost of Windows upgrades can NOT be deducted as a gambling loss." _______________________________________________ Asterisk-Dev mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-dev To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-dev
