Re: [Asterisk-Users] HDLC errors on PRI
The blanket statement that it's a motherbord or card problem is thrown around far too readily IMO. This is often just another way of saying that I have two (or more) pieces of hardware that don't play partucilarly nicely together in their default configuration, but I'm too lazy/busy/scared (I'm not accusing anyone here!) to sort it out. Linux offers a great deal of fine-tuning of the PCI bus and the interrupt subsystem, and you can get asterisk/zaptel to work well on most hardware with a little effort. Over the last six months, I have been through this extensively, and lost a lot of sleep in the process. I now have systems that I'd call solid. Start with digium's recommendations with regard to IDE tuning (HDPARM), framebuffer support, ACPI, and APIC. There is a document on their website about optimising your system to support their hardware. Then, look into SMP IRQ Affinity (if you have an SMP system, and wish to leave APIC enabled). You can also search for PCI latency, and see if this helps. Also, different versions of asterisk and zaptel can make a HUGE difference. I have had most success with 1.2Beta2 on my PSTN gateways, whilst still running STABLE on my IVR and VOIP servers. If you have a card that can be upgraded to the new firmware, do it. I've had all 3 of my 405P cards upgraded, and have noticed dramatic improvements in both performance and reliability. Use zttest every time you make a change, and also make sure that you unload/reload zaptel, the card drivers and asterisk each time you make a change. == Rod Bacon Empowered Communications Ground Floor, 102 York St. South Melbourne Victoria, Australia. 3205 Phone: +613 99401600Fax: +613 99401650 FWD: 512237 ICQ: 5662270 == Eric "ManxPower" Wieling wrote: Matthew Fredrickson wrote: Yeah, post your relevant portions of zaptel.conf.

Yeah, post your relevant portions of zaptel.conf. Usually it's a timing problem if you have HDLC abort errors.
