The goal of this book is to present a framework within which the myriad of office technologies and office systems design techniques can be better understood. There are a number of office books which deal with the social/organizational aspects of office automation or with office equip ment introduction strategies. This book differs from those in that it is written by technical computer people for technical computer people. As such, it assumes a general computer literacy and contains a technical emphasis with a social fiber woven in. Besides the framework, we also present the current state of office primitives, office tools, and office tech nology. We cover relevant work on-going by international standards bod ies, and we discuss the concepts that are emerging (or which we feel will be emerging) from universities and industrial research laboratories. Office technologies and techniques are classified as personal environment aids versus communal environment aids. We now fully realize how difficult it is to write a coherent book within this fuzzy, interdisciplinary, rapidly changing field. Concepts have been stressed wherever possible; there are some sub-areas where the generaliz ing concepts have not yet emerged. We also realize the potential danger of obsolescense. We have tried to combate this somewhat by the presen tation of concepts, generic tool design, and emphasizing our framework. This book is not a substitute for reading of the current periodical litera ture - that is where the most timely information lies.Evolution of PABX industry: PABX started as a centralized solution, containing all the computing power, and the resources (Disks, ...
