| 55 | 55 | To understand how the FEP Simulator works, it helps to understand how the actual FEP works. The actual FEP "polls" field stations, over serial communication lines, for traffic data via RPC. For clarity, "polling" is the act of the FEP requesting traffic data from a field station. When "polled", the field station sends traffic data back to the FEP via RPC. Upon receipt of the traffic data from the field station, the FEP then reformats the data into an fep_reply struct and sends it to the ATMS via RPC. |
