Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: ATM inoshanda sechiteshi-based transport layer, uchishandisa virtual circuits (VCs). Ikoku kunobatanidzwa muchirevo chenzira dzomunhu oga (VP) uye nzira dzomunhu oga. Sero rimwe nerimwe reATM rine 8- kana 12-bit virtual path identifier (VPI) uye 16-bit virtual channel identifier (VCI) vaviri vanotsanangurwa mumusoro waro. VCI, pamwe chete neVPI, inoshandiswa kuzivisa nzvimbo inotevera yesero sezvo ichipfuura nemutsara weATM switch munzira yayo kuenda kunzvimbo yayo. Kureba kweVPI kunosiyana zvichienderana nokuti sero rinotumirwa pa user-network interface (kumucheto kwenetwork), kana kuti rinotumirwa pa network-network interface (mukati menetwork).
