Switching and Signalling

Abstract

At the outset of the WIS System Design study it become apparent that the WIS switching subsystem must satisfy communications requirements arising from the functions of its individual users in war and peacetime conditions as well as in periods of crises. The switching system concept was therefore developed by taking into consideration the operational and performance requirements of the WIS network and services. The WIS network is conceived to be based on a common user, basically circuit switched, area grid network, providing situation oriented, low delay, voice and non-voice services, supporting packet and message switches, and capable of accommodating evolutionary trends in services.
