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? Ciao Joerg -- _____________________ Don't PANIC

Well lets do the math: 1 * TDM40B: TDM400P + 4 PORT FXS Bundle = $305.00 http://store.yahoo.com/asteriskpbx/witd4pofxsbu.html 2 * TDM04B: TDM400P + 4 PORT FXO Bundle = $674.00 ($337.00 ea) http://store.yahoo.com/asteriskpbx/newitd4pofxo.html Total = $979.00 Vs this: 1 * Wildcard TE110P = $595 http://store.yahoo.com/asteriskpbx/wildcarde100p.html 1 * CAC Adit 600 (new) with 3 FXS and 1 FXO = $955 Buy it now option http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=51271&item=5771094378&rd=1 Total = $1550 and for that you get 24 FXS (well only total of 24 ports is usaable since you only have a single span T1), and 8 FXO What you really need is only 1 FXS card and 1 FXO card with the Adit 600. If you really go shopping on ebay you shoud be able to get it all for around $500.00 which makes a total of $1095.00. Do your self a favor and go this route. You will save your self tons of trouble.

I just setup one Dell SC420 with just one SATA drive and 512mg Ram ($ 404.00) with 2 TDM04B in it that is 8 FXO ports. And a second system for another customer with 3 TDM 2 TDM40B 8 FXS ports and one TDM01B for 4 FXO's. Both systems are working just fine. -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Joerg Wleklik Sent: Friday, May 06, 2005 8:03 AM To: asterisk-users@lists.digium.com Subject: [Asterisk-Users] 3 x TDM400P in one PC ??

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.
