INTRODUCTION The MAGIC ISDN Telephone Hybrid system enables the forwarding of telephone calls to analogue or optional digital AES/EBU audio-interfaces. Since the system is based on a modular construction it is possible to expand it as desired. The Basic system supports the simultaneous Hybrid-function up to three or four callers, as well as call forwarding to a selected number. In contrast to previous systems, great emphasis was put on using as little external wiring as possible.
