[asterisk-users] TDM2400: some FXS module fail

[Stefano Corsi]

Hello,

I've installed two Digium TDM2400 cards on my server. One has 24FXS 
and the other has 16 FXS and 4 FXO. They are both connected to power.

Unfortunately some of the FXS module fail to initialize and I find 
following messages in the logs (the rest of the FXS modules work 
well). Could someone give me some advice?
