I am interested in understanding a little about how Automated Teller Machines communicated "fault alerts" back to central control departments.
What I know so far is that ATM's have senors that can be triggered should say a cash jam occur. So a 'fault message' is first created locally and is then communicated accross the network back to some sort of monitoring software system such as 'Gasper'.
Would such a fault message be coded as XML and then interpreted by the monitoring software. Or would the fault message be stored in a lower level in a IP packet payload, especially if it were a legacy system?
Any info in this area would be of great interest to me. Thanks
