Abstract

Ifølge oppfinnelsen blir ved deteksjon av det samme DTMF-signal ved senderenden, suksessive DTMF-rammer vedrørende dette signalet etablert. Disse rammene er modifiserte SlD-rammer, og individuell forbindelses- informasjon (rekkefølge, start, varighet) blir tilføyd hver ramme i tillegg lil informasjon om DTMF-signalfrekvenspar, Denne forbindelsesinformasjon indikerer varigheten av DTMF-signalet fra den første deteksjonstids-periode av den første modifiserte SlD-ramme til vedkommende ramme, innbefattet rammen. Den individuelle forbindelsesinforma- sjon forbinder således med hverandre suksessive DTMF- rammer (ramme 1-4) som vedrører det samme DTMF- signal, Ved mottakerenden blir, når den individuelle forbindelsesinfomnasjon for en mottatt ramme ved mot- takelse indikerer at varigheten av DTMF-signalet er lenger enn terskelverdien, for eksempel 40 millisekunder, det DTMF-signal som indikeres ved frekvenspar-informasjonen til de mottatte rammer, generert til en abonnentstasjon. Under venteperioden blir det generert bakgrunnsstøy.
