Definitions

  • Different telephone private branch exchanges which, in addition to the actual switching control, are also capable of controlling or realizing additional control processes which go beyond the actual switching process.
  • additional functions are generally referred to as performance features, a large number of different performance features being known, in particular for the "voice" communication service.
  • Such features include automatic callback when busy or in free fall.
  • a subscriber finds a busy attempt to connect to an internal subscriber station (extension), he can activate an automatic callback request and end the connection. If the desired subscriber position becomes available, the subscriber who activated the callback order will automatically receive a call (callback). After receiving the call, the desired subscriber position is called.
  • the automatic free call back feature provides that a subscriber who calls an internal subscriber station to whom no one answers can activate an automatic callback request. If the desired subscriber is present again and has made a call, the subscriber who initiated the callback request receives a call (callback) after this call has ended.
  • the Siemens product brochure "System Hicom 600” order no. A19100-K3161-G430-01 (esp. Pages 36 and 37) and from the 'Special edition telco report and Siemens magazine COM', "ISDN in the office", ISBN 3-8009-3846-4 is already a program-controlled telephone private branch exchange known with such features.
  • the convenient extension terminals usually connected to the private branch exchange have a special callback button. Pressing this callback button is only evaluated in the known private branch exchanges if the callback is intended to establish a connection between two 'internal subscribers'. Due to the lack of signaling options in the public network, the callback button is not evaluated if an unsuccessful connection setup from an 'internal subscriber' to an 'external subscriber'.
  • the method according to the invention can be implemented in program-controlled private branch exchanges by supplementing and adapting corresponding control programs.
  • program-technical verification of the method and the integration of the same into the existing program structure is a task which is incurred in the normal course of his work.
  • the subscriber terminals connected to a private branch exchange - ie internal - are one
  • Activate callback wherein the same key can equally be used to activate the method implemented in the secondary unit according to the present invention.
  • the control of the private branch exchange - initially evaluating the entered dialing information - does the following determines whether the target participant is to be treated as an internal or external participant. Since the method according to the invention is only intended to be activated when a connection to an external subscriber is to be initiated, the case of establishing a connection to an internal subscriber can also be disregarded.
  • the intended connection does not come about in the course of establishing the connection because e.g. If the external target subscriber currently maintains a connection to another subscriber, or the external target subscriber cannot be reached, even though he is being called by his terminal, the internal subscriber intending to set up the connection can press the 'automatic callback' function key on his terminal and then the unsuccessful connection establishment, e.g. end by hanging up the handset.
  • the control of the private branch exchange stores the dialing information entered by the internal subscriber on the terminal when the destination subscriber is identified, in a redial memory and the connection number assigned to the internal subscriber terminal in a callback memory assigned to the redial player deposited. In addition, a waiting time, e.g. 2 minutes, set.
  • the controller will try to help itself, i.e. without any incentive from a participant the dialing information stored in the redial memory to establish a connection to the external subscriber.
  • the controller recognizes that the connection to the desired destination subscriber is busy or within a call time, e.g. of 30 seconds has not responded, the connection is broken off again and the timer device is started again with the waiting time. After the waiting time has elapsed, another attempt is made in an analogous manner to establish a connection with the target subscriber. Further attempts with the goal of successfully establishing a connection follow after each waiting time.
  • a call time e.g. of 30 seconds
  • voice information is transmitted to this target subscriber from the private branch exchange, e.g. can read as follows: "Please wait, we pass on”.
  • the internal subscriber whose connection number is stored in the callback memory is called.
  • the internal participant e.g. has answered by lifting the handset, a connection from the internal subscriber to the waiting external subscriber is switched in the private branch exchange.
  • the controller can provide a counter which is used whenever the connection is unsuccessful as part of the callback. is sluggishly switched on and after five repetitions, for example, the controller is prompted to delete the recall order.
  • the internal subscriber is called and a message, for example a voice message, is sent to them, which may also contain information relating to the callback request about the repetitions made. For example, a voice message may read: "The requested subscriber cannot be reached at the moment, your callback request has been deactivated".

Abstract

Lorsqu'un abonné interne effectue une demande d'établissement de connexion avec un abonné externe et que l'abonné interne identifie cette demande de connexion comme étant infructueuse, il peut activer une opération de rappel. Des tentatives en vue d'établir la communication avec l'abonné externe sont entreprises à certains intervalles depuis l'installation de poste téléphonique supplémentaire. Lorsque la communication est établie, l'abonné externe transmet un message sonore et l'abonné interne qui a activé l'opération de rappel est appelé. Après avoir répondu, l'abonné interne est mis en communication avec l'abonné externe en attente.
