[Asterisk-Users] Static on TDM Zaptel FXO
Hello All, I recently put in a zaptel 1fxo/1fxs card. I am experiencing heavy static. Even with the pots line disconnected, if I do a dial I still get static. This way I know it's not the line, but rather something on the card. I tried alternate pci slots. This card has a power connector, does anyone know what the power requirements are? The unit is in a small case with a 2.4ghz p-4 and 512mb ram, on an intel board with 533fsb. All other functions are fine. I am using the latest CVS on Debian 2.6test Anyone experience this? Regards, Greg
Hi can the path format be changed on the server, eg can lookup be ../context/1/2/3/123.gsm kind of like what you would have in order to store email across a filesystem, it makes lookups and scalability much much better/faster Iqbal
Hi Gregory, Have you checked that the card is on its own IRQ? There has been a bit of discussion about this type of thing recently on the list, do a search on the archive to find the various threads. Try running zttest and see what accuracy it is reporting - anything less than 99.99% is supposedly bad. Various 'fixes' (work-arounds) are to make sure the zaptel is on it's own IRQ, disable Hyperthreading and remove RAID controllers or any other high-performance devices that support DMA and other things that are likely to compete with the zaptel. Good luck. D.

[Asterisk-Users] Static on TDM Zaptel FXO
Hello, Yes in the bios I set unused irq's. Zttest is sporadic. This is a non HT cpu, on a standard ide drive. It is basically just a p4-2.4 with a single ide, onboard lan, and that's about it. All other asterisk functions work well. Next step I think I'll try it on another board and see what happens... Or maybe recompile the kernel.

[Asterisk-Users] Static on TDM Zaptel FXO
A kernel recompile managed to give me an average of 99.98%, but I am not certain that this is optimal. It seems that I get some background hiss, although the static is gone.

[Asterisk-Users] Static on TDM Zaptel FXO
On a recompile of the kernel I now get a 99.98 average. Static is gone, although quality so far seems not quite there yet. I am also experiencing an odd local echo. I can hear a slight echo locally, but the other end sounds fine, and the other end does not get echo. Even with the pots disconnected, you can hear it. The static would be on all calls. Hooking up a normal phone was ok. The sip>sip phones are perfect too, it was only happening on the zap channel...

I still need to experiment with it, so I am not sure yet. When I have it I will post the settings. I really don't have a clear understanding yet of the principles for using gain. Are there, for example, specific reasons for different settings. All I want is to be sure I can hear the other party, and they can hear me in the proper volume.
