Definitions

  • the invention relates to a method for determining the operating state of at least a part of a telecommunications network, in particular the operating state of any subscriber line in a telecommunications network. Furthermore, the invention relates to an arrangement for performing the method.
  • Connection lines in the telecommunications network represent a serious technical problem.
  • a malfunction is often identified by the user of a defective subscriber line, who reports this to the operator of the telecommunications network.
  • so-called “call centers” are often set up, where the staff working there, in collaboration with the person who reports an error, carries out a rough initial analysis, then creates a "trouble ticket" and sends this to the responsible service technician forwards.
  • this process can be supported with the help of voice machines which perform subtasks of this process, such as assigning a caller to certain responsible persons within a call center, or transmitting a spoken repair order to a specific service technician.
  • a system is known from the prior art in which a connection is set up to an automatic test device from a subscriber line and a test of this subscriber line is subsequently initiated.
  • the test result is transmitted using a confirmation tone that contains a good or bad statement.
  • a disadvantage of this system is that the result of the test is not specified, the output is only made to the telecommunications terminal from which the order was sent, and therefore subscriber connections that are already operational can only be tested.
  • the invention is therefore based on the object of specifying a method which enables the operating state of a telecommunications network to be determined in a simple manner.
  • Acoustic and text-based systems are used for the input, that is, the requirement to specify the operating state.
  • An acoustic system can be provided for the processing of tones in accordance with the "Dual Tone Multifrequency Code", or DTMF for short.
  • the 12 keys of a telephone are available. This variant is therefore available for almost all telecommunication terminals, but must the user has knowledge of the functions assigned to the individual keys. The user is therefore advantageously familiarized with the individual functions and the keys to be pressed by a voice machine. It is also conceivable that the language of the user is directly converted into corresponding functions Pressing buttons is usually no longer necessary. This technique is also known as "Interactive Voice Recognition", or IVR for short.

  • HTML has the task of describing the logical components of a document and therefore contains commands for marking typical elements of a document, such as headings, paragraphs of text, lists, tables or graphic references.
  • Another main component of HTML is references to other documents or locations within a document, which are known as "links". HTML has become a decisive standard for the Internet.

  • the knowledge of the addressee must be taken into account again, which is why, for example, for the person familiar with a telecommunications network, this also includes individuals
  • acoustic output for example, texts are used in spoken form, which is done, for example, with the aid of a text / speech converter, or by output of pre-made "samples". An acoustic signal is sampled and the individual samples are saved. This variant is suitable especially for users who are less familiar with the conditions of a telecommunications network.
