Today I had channel 1 on my TDM400 go to sleep, verified by pluggin in known good telco lines in various combinations on channel 1 through 4 - problem is channel 1, not anything external. So after seeing lots of stuff on the list re: TDM400's I power cycled, removed board and let linux say nothing's home, replaced board, told linux to ignore it etc. No OS/asterisk/etc changes made on the box between the it worked stage and it stopped working stage. Any suggestions would be welcome - and it just so happens that a previously RMA'd TDM board should be here tomorrow - so when that one arrives I'll swap modules and see if it follows the module or the board...

No reboot necessary. If that doesn't fix the problem, then you might have a defective module. There was an issue with the first tdm cards shipped (ver e/f) where the first module slot had a problem. Those that received replacement cards found an added jumper wire on them suggesting a printed circuit board trace had been missed (or something like that).

PSU or something similar. I have connected a fan on the same cable where the TDM400P is connected. I will try to remove it Sergio
