[Asterisk-Users] TDM400 - channel out to lunch?

[Steven P. Donegan]

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...
