Abstract

A telephone subscriber's instrument (T) is provided with the usual digit-sending buttons (1 to 0) for sending wanted numbers, and a set of function buttons (A to E). There is also a display device (DS), preferably a semiconductor display of the dot matrix type. The function buttons are located adjacent to the display device, and in the rest state the display can indicate alongside each function button its purpose. The instrument includes a microprocessor which controls operations in accordance with the button operations and the current status of the telephone set. Some at least of the function buttons can have different functions on successive push-button operations, with information relevant to those functions displayed by the display device. <IMAGE>

Description

SPECIFICATION Telephone subscriber's apparatus This invention relates to a telephone subscriber's instrument.

According to the invention there is provided a telephone subscriber's instrument, which includes a display device on which alphanumeric and other information can be displayed, a first set of push-buttons for the transmission of wanted number data, a second set of pushbuttons for the control of subscriber functions, and processing means associated with the push-buttons whereby the current condition of the instrument may be displayed on the display device, wherein at least one of the second set of push-buttons has more than one function interpretation, the interpretation to be accorded to the operation of such a pushbutton depending on the current state of the telephone set, so that successive operations of a said push-button can cause the implementation of different functions, and wherein the display is modified in accordance with the interpretations appropriate to the operated push-buttons.

It is known that a small display screen can be constructed, e.g. based on a semiconductor slice, to be compatible in size and in driving requirements with a telephone instrument. This display can be point-or characteraddressible, and the information to be displayed can be read from memory circuits under the control of a microprocessor. Such a display is more versatile than, for example, a multi-segment liquid crystal display, in which a fixed pattern of elements is illuminated to form complete characters or symbols in preset locations. In the display considered here a dot matrix representation of characters allows nonstandard patterns to be generated, including graphical elements so that varied information, possibly including that known as a Viewdata or Prestel page, can be displayed.

In the present arrangement, a display, preferably of the above character, is used in a telephone instrument in such a manner that the function of the display, as well as the information displayed, is varied under the control of a microprocessor in response to user commands. Thus a more simple and useful interface is provided to the user, to enable a range of telephonic or data services, to be accessed or controlled.

Further, the user commands are interpreted by the microprocessor according to the function of the display at the time of the command, and also according to the current state of the telephone instrument. The microprocessor action in response to the command is determined by a stored program. The possible actions include (a) a change to a part of the display, (b) a change to the whole display, (c) a change of the function of the display, (d) a change of the telephone status (e.g. on hook/off hook, dialling or MF tone pulsing, generation of tones into the telephone receiver), and (e) changes involving reception or transmission of data, either over the telephone connection or over a separate connection, such as a signalling or data transfer circuit.

The transmission of voice, tone and data signals may use analogue or digital means.

A point- or character-addressable display is located on the front face of a telephone. Digit sending from the telephone is by loop break or multi-frequency (MF) pulsing, is controlled by push buttons. The push-buttons control a microprocessor which causes the digit sending pulses to be generated within the telephone circuitry.

The significance of these buttons may be altered in response to (a) the status of the telephone, (b) the status of the display, and/or (c) the status of other buttons on the telephone, so that the response of the microprocessor may differ from the usual digit sending. To simplify, the digit sending buttons, and the additional buttons, are placed in a simple physical relationship to the display screen, simplest being to have buttons at the sides, bottom, or top of a square or rectangular screen. With such a button layout, the display screen information can include symbols or pointers adjacent to specific buttons identifying potential commands which the user can use. The symbols can be amongst those known to be used for telephony functions.

With any button layout, potential commands are identified by assigning designations, such as the characters 'A', 'B' etc. to specific buttons, and indicating on the display screen the potential commands then associated with those buttons. The repertoire of commands can be extended by using two, or more, depressions of the same or different buttons to signify a specific command. In particular, the repertoire can be extended enough to allow representation of the alphabet, so that a series of letters may be commanded, e.g. to spell out a name on the display. Alternatively, or in addition, a keyboard representation of the alphabet may be provided, either laid out in a well-known 'QWERTY' format, or in other formats, such as a rectangular matrix.

In addition to buttons of variable function, buttons of fixed function can be provided. The potential use of these functions can be identified on the display screen, or can be omitted, for example because the user will remain aware of the fixed functions potential at appropriate moments.

An embodiment of the invention will now be described with reference to the accompanying drawing, in which Fig. 1 is a perspective view of a telephone instrument embodying the invention, while Fig. 2 is a block diagram of the "works" of the instrument, with optional items shown by broken lines.

The telephone set T, Fig. 1, has a set of digit-sending push buttons, 1 to O, a display screen, DS, and a number of function pushbuttons, A to E. The layout of the buttons is in this case positionally-related to the screen, with the function buttons along one side of the screen, and the digit-sending buttons below the screen. There may be more or less buttons, e.g. for MF pulsing there may be additional digit sending buttons. Also the buttons may be differently located.

In the idle state the display screen may be blank; or may display information, such as time, date, telephone number, or information received over data or signalling channels such as message waiting information from a PBX or other switching system. It may also indicate an 'idle' function allocation for certain buttons, such as 'A: Voicemail, B: Diary, C: Repertory Dial List, D: Prestel'; or may contain patterns, possibly changing with time, or combinations of the above in different parts of the screen.

In the block diagram, Fig. 2 we see a microprocessor MP which controls the information on the display screen DS via a display contents store DCS and display drivers DD.

The microprocessor monitors the status of pushbuttons 1 to 0 and A to E, as well as the telephone status, such as loop and line conditions, via a status monitor TSM. The microprocessor controls telephonic conditions, such as outpulsing, ringing and connection of the handset to the exchange line EL via a telephone status driver TSD, which in its simplest form is a set of relays or contacts. In some cases, the microprocessor connects a modem M, or other form of signal receiver, either to the exchange line, e.g. as in Prestel operation, or to a separate signalling channel S, e.g. as in some types of PBX.Another option is a real time clock RTC which may be used by the microprocessor to display date and time; to activate preset reminder signals or displayed messages such as appointments; or, in combination with recognition of digits sent and a data table in a tariff data store, TD to display call charging information. Alternatively, information related to the real time clock and tariff dat may be received via the signalling channels S and the modem M.

Operation is controlled by the microprocessor MP in response to the telephone status and the push-button commands. Because of the flexibility of the microprocess programming, the complete range of potential actions of the equipment and the sequence of such actions are not described in detail.

An example of the use of multi-function buttons in conjunction with the display will now be described but this is only one of many potential applications. When the telephone set is idle, the display indicates the 'idle' function allocations for buttons A to E. In the example, the function allocations for buttons A to D are Voicemail, Diary, Repertory Dial Information, and Prestel, and these words or equivalent abbreviations appear on the display screen aligned with the buttons. If the user presses button C for repertory dialling, the display changes to show alternative function allocations for the buttons A to E. There are, for these buttons letter groups indicating the names of the subscribers in the repertory dial list.Thus for letters A to E these groups could be A to E, F to J, K to O, P to T and U to Z, and these letter groups now replace what was previously on the screen. If the user now presses button C for names in the range K to 0, the display changes once more to show specific names previously entered by the user.

The user may now press one or more of the buttons to identify one of the names displayed, according to the display instructions.

In response to this command, the microprocessor causes the exchange line to be seized and the digits needed for the named party to be pulsed to line. These digits and the name of the wanted party now appear on the screen.

The names and associated telephone numbers for this function will have previously been entered by the user, using the function buttons and digit-sending buttons in accordance with the instructions for the user of the telephone.
