[Asterisk-Users] static noise with this hardware any advice

[Jonathan k. Creasy]

The power supply could definitely be the problem. You tried a difference
TDM04B right?

Hi

We have static noise problem on our asterisk server. latest stable
release.
The card is a new TDM04B

We have it installed on the following hardware

Motherboard Intel SE7520BD2SCSI
2x POWER SUPPLY 730W INTEL

I will not mention the other hardware because we have
desactivated/changed 
all the other items
The only 2 items that we have not changed is the mobo and the power
supply.

At first it was on scsi drives but we re-installed using a IDE drive
We deactivated the two onboard nic and tried two different brand.
We have deactivated hyper-treading
We have deactivated USB
We have deactivated SATA
We have tried a noise-cancelling power-bar
We have tried two different phones lines
We have tried several IP phones, Cisco, Snom, Gnet
(There is no noise for a call between two phones)
The phone is connected directly in the nic card so there is no network 
problem possible.
We have tried several TDM Card

Anybody knows if the motherboard or the power-supply could be the
problem ?
