Abstract
A communications device according to the invention comprises a telephone set (7), which has a first control device (9) and a main data memory (8) for storing first data, and at least one data input unit (1) which can be connected to the telephone set (7) and has a second control device (3) and an auxiliary data memory (2) for storing second data which represent a part of the first data and via which the first data can be accessed. Both control devices (9, 3) are designed such that, in the event of a data change in one of the data memories, they allow a corresponding change to be made to the data assigned to them in the other data memory.
