Definitions

  • the invention relates to a method for measuring quality-determining parameters of a message transmission link which is permanently connected at least one and has a central measuring system and has a mobile auxiliary device in which the auxiliary device is connected to the message transmission link in the vicinity of a test connection which terminates the fixed end of the message transmission link.
  • a mobile central unit is connected as an auxiliary device to a special line in the form of an at least one-end fixed communication link.
  • the connection of the auxiliary device is carried out near one end of the message transmission link.
  • a central measuring system (measuring system MSy90) is connected to the special line.
  • the auxiliary device is used to measure quality-determining parameters of the communication link.
  • the invention is based on the object of specifying a method with which the quality-determining parameters of a message transmission link can be determined particularly precisely in sections.
  • a method of the type specified at the outset proceeds according to the invention in such a way that a control signal is sent to the test connection and the measuring system with the auxiliary device, and the message transmission link in two in the measuring system after receipt of the control signal Partial routes is separated, the measuring system sends a signal with an identifier over the one partial route and another signal with another identifier over the other partial route, in the auxiliary device after receipt of the one signal generates an acknowledgment signal containing an identifier and for Measuring system is transmitted, is determined in the measuring system by evaluating the identifier in the acknowledgment signal, to which section the auxiliary device is connected, and the parameters of this section of the message transmission link are measured.
  • the advantage of the method according to the invention is that after separating the message transmission link into two sections, the section can be measured particularly precisely with the connected auxiliary device, since signals fed into the other section of the message transmission link cannot impair the measurement of the quality-determining parameters.
  • the parameters are measured with the auxiliary device, since the measured values can then be evaluated immediately on site.
  • the parameters are stem are measured if the measurement results are to be stored centrally or processed further.

  • the control signal arrives likewise to the test completion 10, in which a subscriber (not shown) connected to the test completion is separated from the message transmission link and thus also from the one section 7.
  • the transmitter 16 is then controlled by the control unit 5 in such a way that a signal with an identifier is sent over a section 7.
  • the switching device 3 is actuated again by the control unit 5, specifically in such a way that the one switch S1 and the further switch S2 change their switch positions (see FIG. 3). Now the one input E31 of the switching device 3 is connected to the further output A32 of the switching device 3 and the further input E32 of the switching device 3 to the one output A31 of the switching device 3, whereupon a further signal with a different identifier from the transmitter 16 via the other section 8 is transmitted.

Abstract

L'invention concerne un procédé pour mesurer des paramètres qualitatifs d'un chaînon de transmission de messages à connexion permanente au moins à une extrémité, présentant un système de mesure central (25) et comportant un équipement auxiliaire (12) mobile raccordé au voisinage d'une extrémité du chaînon de transmission de messages. Pour permettre la détermination très précise des paramètres qualitatifs dans un chaînon partiel (7) du chaînon de transmission de messages, un signal de commande est envoyé au système de mesure (25) avec l'équipement auxiliaire (12). A réception de ce signal de commande dans le système de mesure (25), le chaînon de transmission de messages est divisé en deux chaînons partiels (7, 8). On vérifie ensuite dans le système de mesure (25) à quel chaînon partiel est raccordé l'équipement auxiliaire (12), et on mesure les paramètres qualitatifs de ce chaînon partiel (7) du chaînon de transmission de messages.
