Broadband telecommunications system

(130, 140), the signal processing systems connected to them, and the asynchronous data transmission systems connected to each other and to the multiplexers (130, 140) in the form of a virtual interface between multiplexers (130, 140) (130, 140) is configured in a way that generates virtual connections, and during the process, the call signal is generally processed in a signal processing process and processed to select a virtual connection, the multiplexer (130, 140) is transmitted and transmitted from the multiplexer through an opt-in virtual connection. By default, in the signal processing processor, the specified traffic signal cable (180, 181, 182, 182) and the selected virtual connection are generated by a new signal, the new signal being transmitted to the multiplexer (130, 140), the user information for the call being received from the defined traffic signal cable (180,181,182) in the multiplexer (130,140) as a function of the new signal, converting the selected virtual connection to the asynchronous data transmission mode cells and transferring the transmitted synchronous transfer mode cells from the multiplexer (130, 140) through the selected virtual connection. The invention further relates to a telecommunication system for generating a call generated by a specific traffic signal (180) via a virtual connection to a virtual connection, a call signaling function, or a first call signal for a call,
