A New Software Architecture for Switching Systems

Electronic switching systems were introduced in the mid1960´s, and have since undergone constant modifications to provide new features, expand into new applications, and adapt to new hardware technologies. The increasing costs of software development have led to the need to reexamine the design concepts of present systems and define more cost-effective architectures. The specifications and derivation of a new modular switching system architecture which addresses the problems of constant change are discussed.
