We describe the application of model checking tools to
analyze a realtime software challenge in the design of
Lucent Technologies' 5ESS telephone switching system.
We use two tools: COSPAN for checking realtime prop
erties, and TPWB for checking probabilistic specifica
tions. We report on the feedback given by the tools, and
based on our experience, discuss the advantages and the
limitations of the approach used.
