Configurable software for advanced telephony applications

The term configurable software refers to a concept in which part of the software in a system can be dynamically added or removed as dictated by the needs of the system. The authors describe the GTD-5 EAX, a large class-4/5 digital switching system that uses distributed architecture, and explain the reasons behind its implementation of configurable software. Configurable software helps minimize architectural changes needed to accommodate any additional software needed for system evolution. Also, configurable software provides a foundation and capability for feature packaging. This allows the system to be offered in a variety of packages assigned to meet diversified customer needs.<>
