ABSTRACT
We describe a rely and guarantee method for Timed CSP, by which we specify the behavior of a component belonging to a composite system in terms of what it guarantees to its neighbors and what it relies on from them. We illustrate the method by presenting an overview of our specification of POTS (Plain Old Telephone Service) together with part of a design which provably satisfies this specification. The specification and design deal with safety, liveness, and troublesome race conditions.
