D410E: low dahdi_test results, background intermittent noise

Hello,

I'm having issues with an OpenVox D410E: low dahdi_test results, background intermittent noise.

I've already make sure that the card is not sharing an IRQ with any other device, tried to boot with "acpi=off noapic" but the problem remains.

I see some errors like this on CLI (about 2 per minute):

chan_dahdi.c: PRI got event: HDLC Abort (6) on Primary D-channel of span 3


Please advise what else can I try.


My config/relevant info is the following:


OpenVox D410E

CentOS 6.2 x86_64
Asterisk 1.4.44
DAHDI 2.6.1

Motherboard Supermicro X8SIL-F

what is the version of firmware on D410E? Pls paste me the demsg info to figure it out:
# dmesg | grep Reg
The dahdi-2.6.1 is not fit for old version of D410E.You need to install an older version of the dahdi driver, try dahdi-2.4.1.2. OpenVox will release the latest version of DAHDI to fix the problem.
BTW, are you sure the crc4 is necessary for you e1 line? if not, disable it in the file system.conf.

Thanks.
Switched to dahdi 2.4.1.2, and disabled crc4, and the problem with the background noise during bridged calls disappeared.

But still getting low dahdi_test results:

Should I be worried with this (the voice quality seems ok)?

Hello

I think the dahdi_test is ok,you do not need to worry about it.
