Embodiment Construction

[0025] The system described in Fig. 1 is a system satisfying the DECT standard. Reference 1 denotes a base station BS to which a plurality of handsets HS1, HS2, . . . can be connected via radio channels. The base station 1 comprises in particular: a subscriber line circuit 10, which makes it possible to connect said base station to the switching network via a telephone line 12; and a radio circuit 14, which authorizes communication with the respective handsets HS1 by transmitting and receiving radio waves by means of an antenna 16, HS2, ... dialogue. In order to process all analog-type data during transmission over the basic line, a signal processing element 15 based on a signal processor DSP is provided which processes especially speech signals in order to convert them into digital signals.

[0026] The microprocessor module 20 manages all elements of the basic circuit 1 . In general, said assembly is constituted in particular by: a random access memory 24 (which can be sub...

Abstract

A telephony system is formed by a base station and a plurality of subscriber devices. The telephony system has a callback system for producing callback signals by acting on a sound device, for example, by ringing a sound via the earphone for the users. The callback signals are associated with a message which may be a sound or visualized message. This system is applicable to telephone sets in compliance with the DECT standards.

Description

technical field [0001] The invention relates to a telephone system comprising a base station and at least one subscriber unit for at least one subscriber, said telephone system comprising a callback system for generating a callback signal for at least one of said subscribers. [0002] The invention relates to a method of setting up a callback and a station suitable for such a telephone system. [0003] The invention also relates to a base station suitable for such a telephone system. [0004] The invention further relates to a subscriber unit also suitable for such a telephone system. [0005] The invention has important application in all telephone devices of so-called "cordless" telephones, such as in particular telephone devices complying with the DECT (Digital European Cordless Telephone) standard. Background technique [0006] Such a telephone system is described in Japanese Patent Application No. 5-276230 / 4-101940. Such a telephone system includes a callback system ...
