FIELD: electrical communications. SUBSTANCE: transport of circuit emulation data at low speed of bit transmission in asynchronous transmission mode is improved by stacking data in short bursts according to stacking sync signal that arrives depending on sync signal for shaping asynchronous transmission mode pulse train. Short bursts are multiplexed, conveyed to receiving module wherein they are separated and passed to respective circuit emulation connection at respective service frequency which is recovered basing on characteristics of asynchronous transmission mode connection. EFFECT: improved use of frequency band in conveying circuit emulation data for asynchronous transmission mode. 52 cl, 10 dwg
