CZ382992A3 - arrangement for communication private branch exchanges - Google Patents

Abstract

The call-answering position (ABP) is interfaced to a personal computer (PC) whose monitor (MO) allows presentation of complete conditions including displayed announcements with selectable deg. of enlargement. The computer keyboard (TA) takes over the functions of the call-answering keyboard, and a connection unit (AE) is provided for a Braille terminal (BR) and an horizontal shift device (QU). An audio output connection is available for a loudspeaker or headphone (LS). The enlarged monitor screen display can be varied in colour to suit individual operators' residual vision. ADVANTAGE - Operators with varying deg. of blindness and without knowledge of Braille can handle calls. Errors during learning phase are not recognisable by callers.

Description

The invention relates to an arrangement for communication PBXs, in particular telephone PBXs, with a switching station for blind persons.

BACKGROUND OF THE INVENTION

For blind people, switching stations are known in communication technology and have a separate Braille keypad in addition to the query station operator panel (DE-Z: telcom-report ”4,1981, Hl, pp. 26-28; DE - 29 14 526 A1). These devices are designed for people who have virtually lost sight and who have learned to recognize Braille by touch. For those who have lost sight later, working on these devices means learning Braille, with a teaching period of at least two years.

With residual vision, interrogation stations can also be difficult to recognize, similar to people who have complete vision. For this purpose, the design is known as large-area, whereby optionally one cabinet is provided with these large-area keyboards above the normal keyboards of the interrogation station.

877 A1).

The devices described require a relatively long teaching time.

In addition, it is necessary to learn the layout and operation of the interrogator keypads, while operating errors arising during the learning phase are not kept secret to the calling subscribers.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an arrangement which enables the interrogation station to be operated by persons with varying degrees of vision without Braille knowledge, in which the caller does not detect any operator error during instruction. .

SUMMARY OF THE INVENTION

This object is achieved by an arrangement for communication PBXs, in particular for telephone PBXs, with a switching station for the blind, according to the invention, which is characterized in that the switching station consists of an interrogation station with a display and a personal computer connected to the interrogation station via V- a connection whose assigned monitor allows the display of all states, including the display of the interrogation station display in various selectable sizes, that the personal computer keyboard is redirected to take over the interrogation station keyboard functions and that the personal computer is assigned via another V-interface and a Braille display and horizontal screen shifting device, which has an audio output for connecting a speaker or headphones.

A bi-directional data exchange is performed between the interrogation station and the personal computer, which is carried out by serial interconnection of the personal computer and the V-interconnection of the interrogation station. The magnification of the output characters on the monitor in front of a multicolored background is optional for individual adaptation to residual vision.

According to a preferred embodiment, the computer personnel assigned two banks d? · ¹ · to create internal and external electronic phonebook, whose contents emerge in the form of capital letters, braille letters and / or speech. By using the compact disc memory, additional electronic telephone directories are accessible to the switching station.

Overview of the drawings

The invention will be further elucidated with reference to the accompanying drawing, in which a block diagram of an arrangement according to the invention is shown.

DETAILED DESCRIPTION OF THE INVENTION

An ABP polling record is connected to the KA communication exchange. The ABP polling station is connected to a PC via a V-link, such as a V.24 V-link. The PC is equipped with an MO monitor. and TA keypad. By design, the TA keyboard corresponds essentially to that of known typewriter keyboards, which are also common for people with limited vision. It is also replaceable for one-handed operation.

Another V.24 connection to the PC is connected to the AE connection unit, provided with connections for the QU transverse feed device, the BR Braille line and the audio output for connecting the LS speaker or headphones.

The ABP polling station has an erasable and programmable memory (EPROM) that contains V.24 V-Link Control programs and the ABP polling station. The program controls data exchange between the PC and the ABP interrogation station in both directions. This bi-directional data transfer is performed by serial connection of the PC, while another part of the program is installed in the PC. This gives the possibility to display all states of the ABP interrogation station, including the display on the MO monitor.

Furthermore, the TA keyboard is switched by the program to assume the keyboard functions of the ABP interrogation station. The following is a typical example of key assignment:

Only a small number of ABP polling station keys cannot be replaced by the TA keypad. These are the remaining keys for blocking the internal and external switch, for the authorized switch and for the night circuit.

The size output with the customizable MO monitor is adjustable to several different color backgrounds, so it is the individual residual vision of the operator. For such increased output data, it is adapted to read the lines of the QU transverse feed device, which allows the data to be moved horizontally on the MO monitor.

Two data banks can be accessed through the program part. These data banks are virtually an electronic telephone directory with one internal information (such as name, phone number, department, etc.) and one external information (such as area code, customer phone numbers, etc.) and include a program maintenance department, the ability to print a complete phonebook and security give. The use of compact disc memory will give you additional access to the phone book of your network operator.

The electronic telephone directory can be read using the BR Braille line and can be output via audio output as a synthetic speech using the LS speaker or headphones, especially as an aid to people who have lost sight.

The use of a PC with a TA keypad, the display of the MO monitor from the ABP interrogation display in various sizes, as well as electronic telephone directories allow the teaching of a person with reduced vision in the first phase of text processing on the device. When teaching at the KA communication center itself, the individual operation steps can be checked at the ABP interrogation station so that errors can be corrected and the caller will not detect them.

The ABP polling station can also be operated by a person with no vision at all without being connected.
