Abstract: Method for setting up telephone-to-telephone calls using telephones connected to a PSTN/ISDN access network and using a separate packet-switched network as a by-pass network, wherein telephone gateways (GW) provide bridges between the access network and the by-pass network, and connections are established between a calling party (A) telephone and a first gateway (GWa) and between a second gateway (GWb) and a called party (B) telephone.

Abstract: The present invention relates to a method for supporting traffic analysis, especially in an ATM (Asynchronous Transfer Mode) network, in which a transmission procedure is based on asynchronous time division multiplexing using fixed-length data packets or cells, and for the purpose of providing a method which allows for handling on-line traffic analysis procedures in a more flexible manner, allowing fast updating, and rendering only one explicit notion of time, and without any risk of inaccuracies. Used in combination are a data accumulator (DA) and a chronometer scheduler (CHR), said data accumulator (DA) including a channel data table (CDT) which is continuously updated by the traffic data (CAm) to be analyzed, and said chronometer scheduler (CHR) including a scheduler table (CST) which is continuously and sequentially (SW1-SWn) selecting the next traffic analysis job (CAn) to be executed.
