Remote operations: from a generic model to the OSI and ITU SS7 realizations

This article gives an overview of the concept of remote operations and its use in OSI and telecommunications signalling networks. It builds upon the latest results of the ITU/ISO collaborative standardization work on that subject, where a clear distinction has been introduced between the remote operation service (ROS) model and its OSI realization, known as the remote operation service element (ROSE). The article shows that the transaction capabilities of signalling system number 7 can be viewed as a specific realization of the ROS model
