Establishing telecommunications call paths in broadband communication networks

In this method is selected, the speech signal in the input network node (10) of the modulated signal stream and inserted into paketizovaného virtual circuit (PVC) with a constant bit rate (CBR), which is transmitted to the output node (10). Between pairs of nodes in the network (10) to provide multiple pairs of packetized virtual circuits (PVC) with a constant bit rate (CBR), in response to the request to establish the connection from the input to the output node (10) for a call, the signal current when first determines whether any packetized virtual circuit (PVC) free channel, subsequently removed signals for said call from the signal stream and inserted into the packet with a constant bit rate (CBR) paketizovaného virtual circuit (PVC) which has a free channel. telecommunication network including access switches (1) and the transmission network (10), which are some of the access switches (1) connected. Access switches (1) contain a device (540) for converting synchronous pulse code modulovanýŕ
