Definitions

  • a broadband communication system for example a local data network LAN
  • a local data network LAN is installed in many areas today.
  • Such a local data network can also be constructed, for example, in the form of an emulated LAN based on an ATM network. Regardless of the structure of individual local data
  • an ATM network is often installed in order to connect several local data networks.
  • FIG. 3 shows a transmission link between the subscriber line device and the switching termination device according to ITU-T G.960, including a transmission system according to the invention in the region of the Vi reference point.
  • the two conversion devices IWF shown each serve for the conversion time multiplex data in ATM cell data and ATM cell data in time multiplex data and each contain a channel multiplexer / demultiplexer CM / DM in order to distribute the digital signals of the individual time multiplex channels to the respectively assigned ATM cells or from the ATM cells recover and distribute in the assigned time-division multiplex channels.
  • the structure of the ATM network is insignificant for the invention, so that it is not explained in detail here.
  • the device IFW for converting time-division multiplex data and ATM cells can be implemented both as an independent device between the line termination LT and the assigned user interface UNI of the ATM network ATMN, and as an input arrangement for the user interface UNI or as an output arrangement for the line termination LT . Accordingly, it can also be implemented as an output arrangement of a switching termination device ET or as an intermediate arrangement.
  • ATMN user interfaces UNI are shown directly at the switching node ATM hub or at the ATM add / drop multiplexer ATM-DMX, this has no effect on the actual form of implementation of the ATM network, but merely shows the arrangement of the individual elements in relation to an information flow.
  • the subscriber line devices SQ shown in FIG. 2 are each coupled to the user interfaces UNI via a line termination LT and a device IWF for converting time-division multiplex data and ATM cell data.

Abstract

Système de transmission destiné à la transmission de signaux numériques se présentant sous forme de canaux de multiplexage temporel, entre un terminal de commutation (ET) et une terminaison de ligne (LT). Aussi bien le terminal de commutation (ET) que la terminaison de ligne (LT) sont connectés sur une interface d'abonné (UNI) d'un réseau ATM (ATMN), via un dispositif (IWF) pour la conversion des données de multiplexage temporel dans des cellules ATM, ou des cellules ATM en données de multiplexage temporel, de sorte que grâce au dispositif précité, un canal ATM virtuel est associé à chaque canal de multiplexage temporel.
