FIELD: communications engineering. SUBSTANCE: method and switching system 150 are meant for local, dynamically interconnected digital synchronous multiplex or nonmultiplex, or asynchronous service networks used as common service communication facility 220 for three or more switching devices 200, 210. System has long-range service network with at least one central exchange 10 and one or more peripheral stations inside regional sector; mentioned common service life is adaptively shared according to demand curve among mentioned switching devices. According to invention, information is transmitted through mentioned switching system 150 for every combined digital signal 100 subject to transmission through mentioned service network so that mentioned transmission of digital signals 100 individually for each time series corresponds to direct transmission independent of each data series of digital signals 100 transmitted or not through mentioned system. EFFECT: enlarged functional capabilities. 30 cl, 27 dwg
