I am not very familiar with analog cards and DAHDI.
Yesterday my FreePBX system smelled funny for a few minutes and after that my two FXS ports (used for fax machines) on my TDM400P do not work anymore. (The two FXO ports on the same card still work.)
I have an identical card as a backup on my shelf.
Do these cards have some kind of MAC? Anything I need to change in the config when I exchange the card? Or can I just replace it?
I could also replace the FXS module, but I am too scared the card might be defective and destroy the module.
Thanks for your help! I need to be up and running by Monday morning 8 am
