Can anyone clue me in about these T400 T1 cards I see advertised? I hear they are Digium Clones. Is there some reason to avoid these? How do they compare to TE410P's for example. Bart
They are based on the open source zapata telephony tormenta II cards. They work but offload quite a bit to the server from what I understand. The new boards are not open source and take quite a bit of load off of the server. That is my understanding anyways.

This was the single biggest change between the TE400/TE410. The other is the expansion interface for the voice processing module. I also believe that the TE410 has significant improvements for PCI compatibility. -A.
Little personal preferance here (and hopefully some payback for some help you gave me a while back). My experience has been that unless you have echo cancelation on the hardware, the hardware isnt worth purchasing. This holds for the TDM and T cards right from Digium. If I am going to do a T1 install, I insist on the high end quad port card because it is the only one with hardware echo cancelation. Other good cards to look at are the Sangoma and the Rhino of which I have had good results from as well. But the low-end Digium and so far, any clone card, aren't worth the PCB they are printed on.

Personally I have found them to be a little touchy. I have worked on a few and they needed their own version of the Zaptel driver rather then the stock one. The genuine Digium items come working right out of the box for me. Had some issues with newer machines too, though none with older. Overall they seem to work, its just when you start using them heavily they seem to flake out and drop calls, cause line noise and all manner of little annoying things. My 410's have never done that. That said I never connect them to a public system, they (both 400 and 410) are used as interfaces to traditional PBXs so echo isnt usually an issue. -Jonathan -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Bart Fisher Sent: Tuesday, May 23, 2006 10:49 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: [Asterisk-Users] What about T400 T1 cards?
