Development and application of the 188-220 protocol test tool (PTT)

The 188-220 protocol test tool (PTT) was developed by the US Army CECOM Software Engineering Center. It combines software and hardware to monitor, decode, display, and analyze MIL-STD-188-220 traffic on the combat net radio (CNR) network. It operates under the Microsoft Windows NT operating system on a Pentium-class personal computer. This paper describes the functionality, capabilities, development process, and application of the PTT.
