Hi, folks, First of all, I'd like to extend my hearty thanks to Soekris Engineering for producing an excellent product line. I've deployed net4501- and net4801- based firewall/VPN endpoints (mostly running m0n0wall[1]) for a number of clients, and the results have been truly excellent. Sturdy, reliable, and powerful enough to do the job.
So, in the process of experimenting with VOIP I'm getting my hands dirty with various distributions of Asterisk on various hardware configurations. For my own home office PBX, the Soekris net5501 seems to be the best fit - it makes no noise whatsoever, is physically small, consumes very little power, seems to be powerful enough for my needs, and has room for an FXS/FXO[2] adapter card. Best of all, AskoziaPBX[3] is rapidly shaping up to be an excellent Asterisk implementation well-suited to the net5501, much in the same way that m0n0wall is an excellent firewall/VPN endpoint. Here's my question: Will the Digium TDM400P[4] (with 2ea S110M FXS [5] and X100M FXO[6] modules) work in my net5501? If so, will I need a supplemental power supply such as the Digium PWR2400B[7]? If so, any suggestions on how I'd shoe-horn it into the case after installing the TDM400P? I saw the April 2006 thread on this list about the TDM400P on a net4801, in which Kevin Fleming wrote[8] that "the ringing generators on the FXS modules require more current on the 12V power supply than the PCI spec allows." This sounds plausible, but can someone confirm? On a related note, I currently (heh heh) have the 1.5A power supply for my net5501. So far it's been sufficient for the experimentation I've done. However, I'm happy to pick up the 2.5A supply if adding the TDM400P (+ modules) and a 2.5" hard drive will require me to do so. FWIW, I'm confused about the power requirements after having done some homework and come up with this: The Digium web site says that the TDM400P is a PCI 2.2 card[4]. The Soekris web site says that the PCI slot on the net5501 is 3.3v only. I'm not clear after skimming Wikipedia article[9] on PCI as to whether PCI 2.2 is 3.3v- only or if it's just that 3.3v is a commonly used implementation. Obviously, I'm not an expert in such things. Any advice/feedback would be appreciated. thanks, Graham Freeman General Manager, Cernio Technology Cooperative Email/Jabber: [EMAIL PROTECTED] +1 415 462 2991 home office (0900 to 2100 San Francisco time) www.cernio.com [1] m0n0wall - http://m0n0.ch/wall/ [2] FXS = the port you'd plug an analog phone into.
