Definitions

  • the present invention provides a method for assessing how susceptible a TMP connection within a binder is to the effects of crosstalk, relative to the other TMP connections within that binder.
  • the present invention provides a metric indicative of the susceptibility of a TMP connection within a binder to the effects of crosstalk, relative to the other TMP connections within that binder.
  • ⁇ . . , , L , and ⁇ are variables
  • the present invention provides a method of operating a communication system, the communication system comprising a transmitter device connected to a plurality of wire connections, the transmitter device being operable to transmit signals onto the wire connections over a plurality of different channels, the method comprising: for each channel: measuring, for each of the other channels, an electromagnetic coupling between that channel and that other channel; and determining, using the measured electromagnetic coupling measurements for that channel, a score, the score being indicative of how well that channel performs as a direct or an indirect coupling between the transmitter device and the one or more receivers; and operating the communication system in dependence upon the determined scores.
  • the PC-MOP module 1690 may use data reported back to it from the end user modems 51 , 52, 53.
  • the processes and procedures for achieving this are largely conventional and well known to persons skilled in the art and so they are not discussed in great detail herein except to note that it may utilise a backward path from the user modems 51 , 52, 53 to the AN 16.
  • This may be achieved in practice in that the user modems 51 , 52, 53 are transceivers capable of receiving and transmitting signals over the TMPs 21 , 22, 23 as is the AN 16.
  • the PC-MOP module 1690 specifies that those first, second, and third TMP connections 21 , 22, 23 are to be used as direct channels from the transmitter 16 to the modems 51 , 52, 53 respectively.
  • the PC-MOP module 1690 allocates, based on the determined metric values, the first, second, and third TMP connections 21 , 22, 23 respectively to the three modems 51 , 52, 53.
  • the TMP connections 21 , 22, 23 are then connected or attached to the modems 51 , 52, 53 respectively, according to the allocation.

Abstract

L'invention concerne un procédé et un appareil permettant d'exploiter un système de communication, le système de communication comprenant un dispositif émetteur connecté à une pluralité de connexions filaires, le dispositif émetteur pouvant être exploité pour transmettre des signaux sur les connexions filaires sur une pluralité de canaux différents, le procédé consistant à : pour chaque canal, mesurer, pour chacun des autres canaux, un couplage électromagnétique entre ce canal et cet autre canal ; pour chaque canal, déterminer, à l'aide des mesures de couplage électromagnétique mesurées pour ce canal, un score, le score étant indicatif soit de l'intensité avec laquelle le canal affecte les autres canaux par l'intermédiaire d'une interférence de diaphonie provenant de ce canal, soit de la sensibilité de ce canal à la réception d'une interférence de diaphonie provenant des autres canaux ; et exploiter le système de communication en fonction des scores déterminés.
