Circuit arrangement for ancillary dialling devices of telephone subscribers

摘要

The invention relates to a circuit arrangement for ancillary dialling devices of telephone subscribers, in particular for subscribers on a telephone PBX system, with a main keyboard for entering alphanumeric characters into a memory unit and a display device (main display) for displaying the input and output of the alphanumeric characters and a dialling information transmitting device. Telephone number identifiers and the corresponding name identifiers of subscribers are assigned to speed dialling keys with the aid of the main keyboard (AT) and the process controller (AS), and are transferred to the semipermanent memory area (SSP) of the memory device (SP). The name identifier is furthermore transmitted by the process controller (AS) to the individual displays (ED...) of the corresponding speed dialling keys (ZT...) where it is visually displayed. The input information is displayed on the central main display (AD) for monitoring purposes. Ancillary dialling devices of this type are provided for telephone subscribers, in particular for telephone subscribers on a telephone PBX system. Original abstract incomplete. <IMAGE>
