As to why, the CPU was best value at the time and 533 FSB had just been introduced. The other components all seem to be solid performers in their classes. I will soon add a second drive - software RAID1. Personally I would not be deploying these for commercial use, as I feel the uptime is still not there.

I have two identical P4 2.4 boxes with Intel 845 chipsets running updated, stripped down Redhat 7.3 and custom compiled kernels containing nothing more than is required for asterisk in a headless, ssh access only situation. All onboard sound, USB etc. is disabled in the BIOS. One box has 3 x TDM400P - 2 x FXO and 8 x FXS (latest rev) all on individual IRQs. Until a couple of months ago it had 2 x X100P and 8 x TDM400 FXS and required driver reloads about every couple of months over a 1 year period. I replaced the 2 X100s with the TDM FXOs for a few reasons including a hoped for improvement in reliability. In the 2 months since, I have had to reload the drivers once - the logs showed 4 error mesages, "Ouch, part reset, restoring reality" for each of the ports on one of the FXS cards. The second box has a single TDM with 4 x FXO which is IAX2 trunked to the first. It originally had 2 x X100Ps and gave no problems at all for a year. In the 2 months since replacing with the single TDM, the drivers have needed reloading once, with no sign of any errors in logs. Apart from the above, I have been very happy the system and have had no echo problems.

What you have to be aware of is that Digium Zapata cards do not have a buffer on them to handle interupt misses. Zap cards generate an interupt 1000 times per second. At the point you are installing 12 ports, don't go with TDM cards. You are at a point where you will have trouble with power and you don't have an easy expansion plan. You would be better off with a T100P and an appropriate channel bank. At that point you are ready for expansion . -- Steven Critchfield <[EMAIL PROTECTED]> ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

The actual number of cards supported in any pc is related to a lot of other unquantified parameters besides card types. Interrupt latency, PCI bus, etc, have had a major impact on some motherboards with only a single card installed, while other systems seem not to be impacted and can have multiple cards installed. Interrupt sharing can be accomidated, however which cards (and their associated workloads) are important. The topic cannot be discussed in generic yes/no terms. I'd have to guess that somewhere near 80% of the * user-list folks are small soho implementations where the answers to your questions are unknown. Of the remaining users, I'd also have to guess there are very few that actually have the technical knowledge/experience to accurately answer your questions since it seems part of the answer is related to specific motherboards. The only way to get accurate answers is set up a test system and try it, knowing there is a high probability you'll need to try several different systems or motherboards to find the combination that works in your case. ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

That is why there is a power plug on the card to get more power into the card to support the phone signalling. You may have had a small power brown out and it caused your power supply to drop below what the card was happy with. Make sure you have a quality power supply in the computer that has plenty of surplus wattage. Then make sure your machine is on a UPS to make sure the power supply has enough clean power to serve your needs. -- Steven Critchfield <[EMAIL PROTECTED]> ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
[Asterisk-Users] system reboot often?
I just deployed * on my home system last Sunday. 2x since then the Zap hardware seems to have malfunctioned on some way. One time it would just screech out one FXS, even though it would ring. The other time * would bridge to my FXO but it never got out on the line. I have a new TDM400 with 3 FXS and 1 FXO. Both times I tried unloading the zaptel drivers (which worked) and reloading them, which failed. A reboot of the system brought everything back. Is this common? Are there ways to minimize this? Would a different PCI slot possibly make a difference? Or a different system? Is this just a chronic problem with the Digium hardware?
