Abstract

Oppfinnelsen vedrører en fremgangsmåte og innretning for de- finering av kvaliteten på transmisjon i et transmisjonssy- stem, hvilken innretning omfatter en anordning (504) for overføring av gjenkjennelig prøveinformasjon via en overfø- ringsvei. For å oppnå et pålitelig estimat av transmisjons- kvaliteten, omfatter innretningen en anordning (510) for å foreta informasjonsmålinger av den mottatte prøveinformasjon, hvilke målinger viser om informasjonen gjenkjennes"eller ikke, og en anordning (510) for å definere transmisjonskvali- teten på det tidspunkt på grunnlag av målingene som foretas i løpet av et forutbestemt tidsintervall.The invention relates to a method and apparatus for defining the quality of transmission in a transmission system, which means comprises a device (504) for transmitting recognizable sample information via a transmission path. In order to obtain a reliable estimate of the transmission quality, the device comprises a device (510) for making information measurements of the received sample information, which measurements indicate whether the information is recognized or not, and a device (510) for defining the transmission quality of the time on the basis of the measurements made during a predetermined time interval.
