Definitions

  • This invention relates to data and voice communication devices, and in particular to a unit which is adapted to both send and receive communications in the form of analog signals such as voice, as well as digitally coded information such as facsimile and computer encoded messages.
  • the present invention seeks to provide a unit which combines a number of the above functions, in such a way as to "free-up" other equipment so that it is not required to be permanently connected to a telephone line, or left waiting in a "host mode".
  • the present invention provides a data communication device, including means for connection to a communication line, and at least one connection means for external analog or digital message input and output; means for converting analog messages to digital form, buffer storage means for storing incoming and/or outgoing messages, and control means adapted to control the storage and forwarding of the said messages in both directions.
  • the device may incorporate means for encryption/decryption of messages so as to enable source communication links to be established.
  • the device incorporates a conventional telephone function, including a key pad and display, and a hand set to enable direct handling of voice messages.
  • a conventional telephone function including a key pad and display, and a hand set to enable direct handling of voice messages.
  • the device incorporates a socket into which a conventional telephone can be connected.
  • connection for communications comprises a standard telephone line connection
  • connection means for other devices include serial and/or parallel ports for connection of devices such as a fax machine and a computer.
  • the message storage means preferably comprises a RAM memory and may also include magnetic tape or other mechanical storage devices, in order to expand its capacity.
  • analog to digital conversio means
  • the functions of the device in the case of the present invention preferably include the functions of determining what type of connection is being made using the standard "dual tone multi-frequency" signalling system, and converting voice waveforms to digital signals (codec) .
  • the type of connection to be made is determined by DTMF transmission and detection.
  • DTMF Transmission and detection
  • the aim is to make multiple use of the phone acceptable even without the benefit of ISDN (Integrated Service Data Network) support, though the provision of ISDN makes it no less useful because of its storage and switchin functions.
  • ISDN Integrated Service Data Network
  • control means for the device includes a microprocessor and a "ROM" program memory.
  • microprocessor 18 controls the overall control of the device.
  • ROM 20 read only memory
  • the component (2) marked "D/A converter” has thre particular functions which operate bidirectionally:
  • the device When the device answers an incoming call (either on user pickup or after a specified number of rings) it will regularly issue a single DTMF code via the modem clip (6) (probably chosen from the ABCD group of tones) whether the telephone user picks up the phone or it is answered automatically by the device. It then listens to the line to detect if there is a data transmission coming in. If it is on auto-answer it transmits a regular answerphone-like message.
  • A) that establish the type of transmission required using a non-negotiable offer and acceptance or rejection. (This is necessary because the range of possible modes cannot be inferred simply from a carrier in a reasonable length of time) .
  • the device will then instruct the modem (6) to generate tones of the appropriate standard (Fax group 3, v32.bis, v21 etc) b.
  • a fax, modem or telex machine is calling which does not understand the system. In this case the modem can be preset to recognise one of several standard tones and respond in a less reliable way but one which allows the user to receive the regular messages they expect.
  • a person is calling to leave a voice or other message, and is in possession of a touch-tone phone. They can shortcircuit the.
  • a person is calling who is not aware of the system. In this case it acts like a standard answerphone.
  • a short message using DTMF tones or a control function is received. This may be for instance a call-back request, a request for a certain type of information, a "bleeper" message or a message to a home remote control system.
  • the machine may continue to listen for recognised tones. If it detects them it will request the user to replace the handset (via the display (8) and/or a tone) and continue as above.
  • incoming messages there is in general no need for incoming messages to have any known identification or routing information.
  • the message might contain such information, to provide distribution capability on to internal computer networks for example, but any such routin will normally be done outside of the device.
  • the device may optionally incorporate some method of encrypting and decrpting messages to improve the security of the message transfer.
  • Outgoing messages placed in the memory (10) of th machine paired with the phone number or numbers to which they are to be sent, entered via keypad 12, may be sent immediately or at some preset time.
  • the device attempts to place the call in the normal fashion (respecting relevant statutes for redialling delays etc.) and when it has finished dialling it listens t the line to detect the call completion. What happens then depends both on the type of message and the response.
  • the device has a fax or modem message and is answered by a conventional fax or modem device, then transmission is sent as far as is possible using the standard protocols.
  • the device has a modem message and is answered by a conventional fax machine. It converts the modem message into a raster image (this may be done in advance and stored) and transmits the message or fax message.
  • the other part of the device is the local communication which is generally desynchronised (though the size of buffer and period of delay may both be almost reduced to zero) .
  • the aim of the device is to make it a general purpose device that can be connected to a number of different input and output devices that are in common use, so that the user can obtain the required utilility in an economical fashion.
  • the device therefore typically contains at least two serial or parallel ports 14, 16, and a telephone handset or equivalent for voice messages.
  • a number of input devices may be linked to the device to generate outgoing messages.
  • a microphone for input of voice messages generally through a conventional telephone handset (including the provision of suitable identification) .
  • the inbuilt keypad (12) which can be used to enter telephone numbers and also short messages for transmission.
  • c. A fax-type scanner which can convert a page into a series of greyscale pixels. (A conventional fax machine may be used if it has a suitable interface.)
  • a conventional keyboard connected via a serial or parallel line.
  • a computer (or any other device) which transmits complete messages to the device using a serial or parallel interface.
  • the format of these messages is not determined by the device except inasfar as it is necessary to determine (1) the destination of the message (2) the length or ending of the message. It can therefore include any digitally encoded information.
  • the start of the message conforms to the X400 standard for electronic messages, then the header will be scanned to detect the destination of the message, which will be either a telephone number or possibly a name whose telephone number is already stored in the device's memory, and perhaps a transmission time.
  • Outgoing messages may be labelled or unlabelled. The label consist of the form of the message, a telephone number and a time delay, together with a identification number. Messages are held until they are properly labelled.
  • the following output devices are envisaged: a. An inbuilt speaker which can transmit voice messages and possibly text messages via a synthesiser. b. A small display which is used for displaying the labels of received messages and also for showing the first lines and perhaps the whole of text, graphic or fax messages. c. A conventional printer. Generally suitable messages may be sent to a printer as soon as they are available. Subsequently the message may or may not be deleted from the device's storage. d. A computer connected to one of the serial or parallel ports. When the device is connected and has information to send, it may transmit regular signals to the computer until it responds to say that it is ready to receive data. It then transmits one or more messages, using a conventional format such as that stipulated by the X.400 protocol.
  • the messages may be text, graphics or sounds. In the case of received messages that already have X.400 headers these are transmitted faithfully, though the device may not itself have any dispatch functions for internal networks. e. Some secondary storage device. f. A home control system than can activate floodlights, turn on the central heating etc.
  • the despatch of messages in both directions is automatic.
  • the message can be deleted if storage space is required for other purposes.
  • the transmission and reception lists can also be changed directly using the device's keypad (with suitable security provisions) .
  • the device can also have a number of ancillary functions, such as identification, the storage of telephone directories, maintenance of transmission and receipt records, accounting of telephone charges and archiving of messages.
  • ancillary functions such as identification, the storage of telephone directories, maintenance of transmission and receipt records, accounting of telephone charges and archiving of messages.
  • the preferred form of device can perform the following functions: a. Store messages in both incoming and outgoing directions; b. Handle voice, fax and other digitally coded messages; and c. Work with conventional telephone exchanges as well as ISDN exchanges.
  • header information identifying the type of message may of course be carried on that line.
  • a version of the header information may also be carried with the data on the data channel.
  • the header information may also carry an indication of this.
  • the dual tones are referred to using the conventional 1-9,0,*,#.A-D for the 16 possible tones. It will be noted that all codes are terminated by # to provide expansion capability without need for any delay.
  • a Messenger is ready and waiting for a signal.
  • the messenger will respond within a short time period to indicate its readiness to accept a message.
  • the response of the Messenger is to generate the appropriate modulation tone and sign-on signal for that class of fax.

Abstract

On décrit un dispositif autonome de transmission de données destiné à recevoir et à transmettre des messages analogiques ou numériques incluant des signaux vocaux, des données de télécopieur et/ou numériques et comprenant un microprocesseur de commande (18), une mémoire vive (10) pour le stockage en mémoire tampon, une connexion externe (4) pour ligne téléphonique et des connexions locales (14, 16) pour télécopieur et ordinateur. Lors de la réception d'un message, le dispositif identifie la nature du message arrivant en provenance d'un en-tête relié par l'intermédiaire d'un dispositif similaire en train de transmettre (ou bien par l'absence de cet en-tête) et il se commute alors lui-même en mode approprié dans lequel il peut stocker le message sous forme numérique, en convertissant tout d'abord sa forme analogique si nécessaire.
