Test methodology for the level two subsystem of an X25 procedure for data terminal equipment
Abstract
A communication network test methodology in accordance with the Italian public network protocol is discussed. The general principles are not valid for subsystems of order greater than two. The basic approach is an analysis by states, classifying the several states by criteria such as accessibility, observability and excitability. This method is capable of in depth verification of the system, although there may be problems concerning the complexity of the test.
