We've got four TDM400P cards in one PC running without any trouble, since January.Hi Folks,
Does anybody have experiences with plugging 3 TDM400P cards in one PC??
I think about a Asterisk box handling 8 incoming analogue lines and providing 4 lines to an old analogue PBX.
I read a lot about trouble with the TDM400P cards so this idea seams to be not really god, or?
It's not a fair comparison between new cards that come from Digium with support and a second-hand channel bank from Ebay. If an analog phone interface doesn't work, I can figure out if the problem is the card, the wiring, or the phone with a voltmeter, and unless the entire card gets fried, it's just one phone that's out, and even so, unless the entire computer is fried it's only four. If a T1 interface, technology with which I have no experience, fails, the entire system is out, and I don't have a clue how to find out what the problem is, is it the wiring? The channel bank? Is tab A plugged into slot B? Did the channel bank turn up on Ebay because someone else couldn't get it to work either? Lastly, I was told that I would have to bring in a technician to wire up a channel bank, I didn't have to do any wiring with the TDM400P's - I plugged in the cards, took the RJ-11's out of the PBX I was replacing, and plugged them in to the cards.
