Abstract:
A method of establishing data signal connections between data terminals connected to a circuit-switched switching center, and/or between the data terminals and a separate data network connected to the circuit-switched switching center via one or more connecting nodes, which comprises:defining a normal transmission capacity in a circuit-switched switching center available for normal data signal connections; defining a first traffic load threshold and a second traffic load threshold in the switching center; if a traffic load in the circuit-switched switching center or a network including the switching center lies below the first traffic load threshold, providing additional transmission capacity for the data signal connections to be established in the switching center, in addition to the normal transmission capacity available in the switching center for the normal connections; if the traffic load exceeds the first traffic load threshold, providing only transmission capacity currently available for normal data signal connection for the data signal connections to be established; and after the traffic load undershoots the second traffic load threshold, providing additional transmission capacity in addition to the normal transmission capacity previously provided for data signal connections form at least some existing connections available for the normal connections for the data signal connections to be established; if the traffic load occurs in the network including the circuit-switched switching center exceeds a third traffic load threshold, removing the additional transmission capacity.
