An industrial experience on LOTOS-based prototyping for switching systems design

This paper summarizes the experience obtained in the definition of a LOTOS based development methodology and its pragmatic introduction in common industrial practice.
The work has been done within a technology transfer model where the development of medium-to-large size case studies plays a predominant role. A case study, development of a gateway between DSS1 and SS7 ISDN signalling systems, was chosen as a representative example of industrial product in the switching application domain. The case study was developed by automatic code generation from a LOTOS specification. Later, its functionality was enhanced to provide demo facilities in order to evaluate the development approach.
From this experience a practical methodology to combine LOTOS with conventional techniques has been defined.
