Abstract

The system may be built around a telephone of conventional type with the aid of a microcomputer, or several micro-computers working in conjunction with each other, and a number of specific functions which e.g. are formed as modules. The computer has a programming unit for automatically switching on and off the modules at different times. This operation with the modules takes place manually when they are not computer-controlled. One module is an activity indicator comprising differently coloured lamps which when ringing occurs, shows the caller which degree of accessibility the rung person has. - The second module is for coded through connection with the function that only persons using a special code may have access to the rung party. The third module contains exchangeable synthetic speech units and one for answering of suitable length with digitally stored sound for the rung person to record in advance a suitable response. The fourth module comprises a memory for the telephone number of the caller, and specific personal and/or business codes.
