ISDN Centrex applications in a large multinational company

Abstract

Six cost-effective and productivity-enhancing ISDN applications for use in office environments are presented. The applications include ISDN multipoint, ISDN host interface for terminal sessions, ISDN telephone call control via data terminal, video conferencing, and ISDN service direct to employees' homes. It is shown that ISDN provides foundations for the applications described. Several applications use off-the-shelf customer premises equipment; others use prototype equipment. Each application addresses a specific communications need.<>
