[Asterisk-Users] static noise TDM400P+T100P+Adtran Channel bank(TA750)

[jong suk Lee]

I just added TDM400P with 4 FXO module card to the
mahcine running T100P with channel bank setup.

I am running redhat 9 on Intel Xeon Server Board
SE7505VB2 with 1G ram.
Process speed is 2.4ghz.

When I get dialtone, I am hearing regular 5sec static
noise.
I tried to disable all the unused devices and make
sure that it is not sharing any irq. I can not get rid
of this static noise.

I saw several posts regarding TDM400P having static
noise problem.
I tried suggestions but none of them seems to solve
issue.

Any help or recommendation would be appreciated.

does card itself have design issue?
