Thanks to previous help from this group, i have now bought a TDM11B and try to run astlinux .
The FXO installs, but not the FXS. It seems to die on the calibration issue.
yes, I have powered the card’s power connector; and I use FXS signalling for FXO module, and vice versa.
I moved the FXS module to different “slots” on the TDM400: to no avail.
I Googled a lot to find similar failures and fixes, but all I found at this stage is to change the FXS module (Unfortunately I have only one).
I am reluctant to conclude that the module is bad (assuming some quality control at Digium), even if some infant mortality occasionally happens.
I am looking for suggestions, ideas, … solutions!?
I don’t even know really, what additional info to give you: maybe you can suggest what part of dmesg screens or other, would be useful
Thanks for the push.
