Neil, I assume you are considering connecting an FXS VIC port to a key system. In that case you would connect to an FXO port on the key system. This would qualify as a "trunk" circuit connecting the two telephone switching devices. You are correct that this is not the best of possible connections. Dialtone is intended to be used as a signal between a machine, (a telephone switch) and a human listening to the telephone handset. It does not do well from machine to machine. In the analog world the best scenario for telephone trunk circuits is the E&M interface. But, your key system nay not support that. Good luck with the FXS/FXO trunking. (Pay close attention to any calls that get refused, as it could indicate that digits are getting lost between the two systems). Bruce
