Circuit for common controlled telephone exchanges, especially private telephone exchanges and special private telephone exchanges, with at least one operator position and an information handling device attached to this position

摘要

The information processing unit (IVE) is operator position-oriented and exhibits several microcomputers (MC...), the first microcomputer (MC1) controlling the voice information detection and conversion whilst the second microcomputer (MC2) handles the control functions for the indicating means (L...) and the keys (DA...). Such circuit arrangements are used, in particular, in air traffic control systems. IMAGE
