Yes, I had a test system with a TDM400P and two FXO modules terminating two BT Featureline Compact lines. However, "had" is the operative word. One of the two FXO modules is now holding the line permanently off-hook - even when the system is powered down. The other module is fine, and the drivers don't see anything wrong with either module. My suspicion is that the one module is dead. I haven't had a chance to pull out the machine and play with it, though. To see if you have a similar problem, connect a phone in parallel with the FXO module. Unplug the module from the line, and check that you get a dial tone with the handset. Hang up, and plug the FXO back in. Then lift the handset again - I get a noisy line with a very quiet dial tone. If you wait long enough, the dial tone will stop and you'll hear the screamer, again very quiet. I've no idea what caused our fault. I don't know of any storms before the failure, and all the other connected equipment is fine.
