Abstract

1. A switching network with reverse trunking scheme resulting in connection switch through with connection path reversal, wherein the subscriber terminals are connected to inputs of input subsidiary switching networks and wherein further subsidiary switching networks are provided, in particular for telephone exchange systems, characterised in that in each subsidiary switching network the intermediate lines (e.g. 1HA1 ... 16HB32, 1ZA1A ... 16ZB1B ... ZZ) which connect the subsidiary switching networks (1TG1 ... 16TG32, 1HKa ... 16HKb, ZK1a ... ZK4d) including input subsidiary switching networks (1TG1 ... 16TG32) are connected to associated inputs in accordance with a reverse trunking scheme in respect of the subsidiary switching network in question and therefore the connection paths are also reversed within the subsidiary switching networks.
