Cough, if Shannons system is anything similar to the one I am familiar with, having logged on with ATN and then logged off, it will not let you log back on again with any system as it assumes there was an error, so prohibits the log on so any stale message doesn't find it's way through. Try using ATN with EGTT and when you get transfer to Shannon, use FANS to log on to them and see if it connects, is the system simple enough to manage that????
