Abstract

A method for transferring data from a first switch to a second switch selectively by line-switching or by packet-switching as well as to a switch for carrying out the method. Data packets are thereby first transferred packet-switched through a packet-switching network to the second switch. With the presence of a corresponding control signal a line-switching connection is established from the first switch to the second switch and the data are then transferred through this connection. Where applicable a renewed changeover to a packet-switching transfer is carried out. A flexible packet-switching or line-switching data transfer linked with dynamic costs between the junctions of a telecommunications network is enabled.

Claims

1. A data switch apparatus, comprising:

a data input;

a packet switch having a connection to a packet-switching network;

a line switch having a connection to a line-switching network; and

a controller that receives data from said data input and sends said data to either said packet switch or to said line switch in response to a control signal that is developed as a result of monitoring quality of service of said packet switching network with respect to an existing transfer of data from a first end terminal connected to said data input through said packet-switching network to a second end terminal.
