1. A method for transferring data from a first end terminal to a second end terminal using a first switch and a second switch, selectively by line-switching or packet switching, comprising:

  • a) locating the first switch between the first end terminal and an access point of a packet-switching network, the first switch being part of a line-switching network or having access to a line-switching network;

    b) establishing a connection via the first switch through the line-switching network from the first end terminal to the access point of the packet-switching network;

    c) line-switching transferring of non-packetized data through said connection from the first end terminal to the access point of the packet-switching network;

    d) packeting of the data into data packets and packet-switching transferring of the data packets through the packet-switching network from the access point to the second switch;

    e) checking repeatedly whether a control signal exists for transferring to a line-switching connection to the second switch;

    f) establishing the line-switching connection, during an existing transfer, through the line-switching network from the first switch to the second switch with a presence of the control signal, if the line-switching connection is not yet present; and

    g) changing-over to a line-switching data transfer during the existing transfer and transferring data over the line-switching connection to the second switch and from the second switch to the second end terminal.
