DE3307169A1 - Telephone set, in particular added-feature telephone - Google Patents

Abstract

An interchangeable module is provided for a telephone set for output of announcements or instructions in the absence of the terminal owner. For this purpose, an externally accessible, socket-like receptacle is disposed in the housing of the telephone set, into which modules with correspondingly different specifications can be inserted. The module and the receptacle are provided with mating contacts. The module contains a solid-state memory for storing speech in digital form, while a control logic with an evaluation circuit is disposed inside the housing.

Description

Telephone, especially

special comfort device The invention relates to a telephone set, in particular comfort apparatus, with additional functional elements, with associated Circuits and components through the formation of independent assemblies in Form of plug-in modules, the combined interfaces as connection elements have, can be used in recordings and received by the housing.

Devices of this type are known, with loudspeaker devices, memory, Hands-free equipment and also answering machines are included in the housing.

Through this answering machine it is possible in a known manner for one absent Record subscriber messages. In order to enable integration in the housing, speech memories are used for transmission a short message of 10 to 20 seconds. Allow these arrangements the direct recording like on a tape recorder. Here the language is through a delta-modulated coder stored in freely programmable memories. Further solutions are known in which speech synthesis circuits in the telephone set and fixed language texts are generated from read-only memories (ROMs). In addition, there are external answering machines that can be connected to the telephone known with magnetic recording of large dimensions and cassette drive, the lack of wear and tear by the mechanical drives and a relative have high power requirements, i.e. a feed from the telephone network is disconnected the end.

The aforementioned delta modulation encoders with storage in freely programmable Memories (RAM) require considerable storage capacities and thus a considerable amount Space requirements. Speech synthesis circuits (LPC coders) come with relatively small storage capacities off, but their voice quality is too poor for everyday telephone use. With however, an improvement in the voice quality results in an increase in the memory requirement accompanied.

In summary, electronic storage media with high Voice quality and low power consumption, as for the supply from a subscriber line is necessary, a relatively large amount of space, so that either only short Texts or texts with poor speech quality can be saved.

The object of the invention is to take into account telephone sets a simple arrangement with an automatic notification device or to create an announcement device that takes up little space and yet versatility enables as well as safe commissioning by the User guaranteed.

This object is achieved according to the invention in that the Housing an externally accessible socket-like receptacle for a replaceable Usable announcement or notification module has a solid-state memory for Has voice storage in digital form and the announcement or notification module as well the inclusion of corresponding contacts to form an interface have, the interface with a control logic inside the housing and evaluation circuit is connected. This has the advantage that by a simple design from a large number of predefined announcement and notification modules an announcement or a note for a caller can be selected as required and can be entered. The replaceable module has a relatively small one Size, as all circuit and functional elements beyond the read-only memory are arranged in the housing of the telephone set. This separation is also the module that can be placed on the outside of the housing is not disturbing. Another benefit is that Power saving in the telephone set, since only the text memory is required must be supplied with power.

Further advantageous refinements of the invention are provided by the Characterized features of the subclaims.

Exemplary embodiments of the invention are shown schematically in the drawings shown. 1 shows a telephone set with a receptacle in FIG Side wall, Fig. 2 shows a telephone set with an overhead receptacle, Fig. 3 is a block diagram of an arrangement.

The telephone set consists of a housing 1, wherein according to FIG. 1, a socket-like receptacle 2 in a side wall 3 and according to FIG 2 is arranged in the cover plate 4 with the functional elements 5. In the Socket-like receptacle 2, an announcement or notification module 6 can be used interchangeably. The recording 2 and the announcement or notification module 6 have not shown in detail Corresponding contacts, so that this creates an interface. It is thus possible, announcement or notification modules 6 with different texts accordingly to meet the requirements and make them functional.

According to the block diagram it is shown that the housing 1 for implementation the required function a caller ID 7, speech circuit 8, control logic 9 and has a digital-to-analog randomizer 10, while the insertable module 6 has a Has solid-state memory 11 for storing speech in digital form.
