Definitions
- the user data transmitted on the twenty transmission channels of a channel bundle 30 are processed in the compression unit 28a.
- the compression unit 28a carries out data compression for the useful data which are transmitted in the channel bundle 30 in the direction of the transport route 22.
- the compression ratio is 4: 1, so that the compression unit 28a on the side of the transport path 22 is only connected to five transmission channels. If, on the other hand, user data are transmitted from the transport route 22 to the network 10 on these five transmission channels, the compression unit 28a decompresses the user data in a ratio of 1: 4. Twenty decompressed transmission channels, which are connected to the time multiplex unit 26a, are required for the useful data transmitted on the five compressed transmission channels.
- distribution unit 14 In addition to distributing the transmission channels on line 24 to transmission channels on line 22, distribution unit 14 thus also has the function of performing compression or decompression for specific transmission channels. In addition, by the distribution unit 14 Signaling channel D3 selected from the channel bundle transmitted on line 24 or integrated into this channel bundle.
- the transport route 22 has a length of 10 km, for example, and possibly contains several sections in the network 10. Because of the compression, only transmission capacities for the transmission of fifteen transmission channels in the network 10 have to be made available for the transmission of thirty transmission channels for user data. Thus, the network 10 is only half as burdened by the rented transport route 22 as would be the case if thirty transmission channels for useful data had to be transmitted on the line 22. This results in cost savings for the operator of the network 12.
- the time multiplex unit 114 connects signaling channels D1 ′′, D3 ′′ on the side of the transport route 104 and the signaling channel D2 ′′ on the side of the switching center 20 ′′ to the signaling channels of the same name on the side of the switching computer 18 ′′.
- the switching computer 18 ′′ thus has access to the signaling channels D1 ′′, D2 ′′ and D3 ′′.
- the switching computer 18 ′′ assigns one of the ten transmission channels of the channel bundle 110 for connections of a subscriber Tlnl ′′ on the telecommunications system 50 ′′ to the traditional network 10. In this case, the switching power and the transmission power of the network 12 are only used slightly.
- the transmission channels of channel bundle 110 are thus used for connections by the Switching center 11 '' to the telecommunications system 50 '' and from the telecommunications system 50 '' to the switching center 11 ''.

Abstract
L'invention concerne un procédé et une installation de traitement de données pour effectuer une commutation entre des abonnés (Tln1'') d'un système de télécommunication (10, 12). Selon ce procédé, une demande d'établissement de communication entre les abonnés (Tln1'') est transmise par une unité de commutation (11'') à une unité de commande (18''). Cette dernière sélectionne une voie de transmission (110, 112) en fonction de la demande d'établissement de communication et signalise, par l'attribution d'un signe, la voie de transmission sélectionnée (110, 112) aux unités de commutation (11'', 20'', 50'') connectées à la voie de transmission sélectionnée (110, 112) qui sert ensuite à la transmission des données utilisateur.
