Gary, Thanks for the reply. > >Is anyone working on a driver for the Ascend NetWarp 128 ISDN Terminal > >Adapter? > > Which chipset does the card use ? There might be a driver for a card with > the same chipset that you could start with. There are drivers for a > number of passive cards which use the Siemens chips (ISAC and HSCX). Here's what I know: 1) It is a passive TA based on the Network Interface model rather than the Comm Interface model. This makes it an excellent choice to avoid the latency hit involved in Sync<->Async translation as well as the UART speed ceiling. 2) The card is PnP and based on the Siemens 2086/2091/82525 chipset. In fact, these are about the only chips on the card at all. 3) It claims to support National ISDN NI-1, AT&T 5ESS, NORTEL DMS-100, EDSI and INS-64 signaling protocols. > You might also check out whether Linux already supports the card. It currently doesn't, but I've checked out isdn4linux and the HiSax drivers and things look promising... So far as I can tell, from bisdn and HiSax, the isdn (B channel) driver should be ok as-is, but disdn (D channel) driver will need additions to support the US signaling protocols. Does that sound reasonable? As far as the actual card support goes, I'm not sure which european cards are closest to it. I've read the Niccy is ISAC/HCSX based, as well as the Teles. Is this the case? > If you get a driver working send a mail to isdn-dev@hcs.de.

I've been in contact with Ascend and am waiting for more information from the Systems Engineers. I'll let you know what progress I make.
