Abstract
For synkron overføring mellom to telekommunikasjonsenheter må anord- ningene alltid være synkronisert. Vanligvis er det nødvendig med et referanse- signal for synkronisering. Referansesignalet kan sendes fra en enhet til en annen, innleiret i datasignalet. Hvis dataene overføres via et overføringsnett, modulert på den måte som nettet krever, mottas ikke alltid referansesignalet av mottakeren sammen med datasignalet. Problemet løses gjennom denne oppfinnelsen ved å omforme referansesignalet før det sendes inn i overføringsnettet, til det frekvens- bånd som benyttes for overføring i overføringsnettet.
