Unified alignment of isdn‐relevant information communications services/applications through a cubic framework
Nobuhiko Shimasaki · International Journal of Satellite Communications · 1991
Abstract A cubic (three‐dimensional) framework is proposed for mapping various information communications services. The framework implies the important aspect of information technology (IT), or C&C (integration of computers and communications) technology as follows. The first axis is based upon the service classification made for BISDN‐relevant services by the CCITT. This ‘communications’ axis covers not only the simple communication, or ‘space‐wise information transfer’, but also messaging, retrieval etc. as ‘the combined space/time‐wise information transfer’. The second axis represents ‘the multiplicity of media use’ in the human interface of information handling systems. The third axis represents the extent of ‘information processing/conversion’ or the level of computer technology penetration. In the latter part of this paper, the important interrelations between computer communications services and ISDN deployment are discussed using the scope of the above‐proposed cubic map. The penetration of PMI (personal machine intelligence) to the same level as telephone set and television set, and the corresponding computer communications services requirements are identified as a fundamental driving force of (N)ISDN deployment.
