Abstract
En analog elektronisk krets er plassert mellom det. sentrale kontoret til en telekommunikasjonsleverandør og kundestedutstyret i et digitalt abonnentlinjesystem hvor det benyttes uskjermede tvunnede trådpar (UTP). Den elektroniske kretsen skiller nedforbindelsessignalene fra oppforbindelsessignalene med et første blandetrinn. Talesignaler, hvis de forekommer, rutes umodifisert rundt den elektroniske kretsen. Nedforbindelsessignalene forsterkes, filtreres, forsterkes igjen med én eller flere spissutligningsforsterkere, og forsterkes så med drivere som tilveiebringer kraften for driving av nedforbindelsessignalet gjennom et andre blandetrinn og til UTP-linjene til kundestedutstyret.Den elektroniske kretsen skiller oppforbindelsessignalene fra nedforbindelsessignalene med det andre blandetrinnet. Oppforbindelsessignalene forsterkes, filtreres og forsterkes igjen, og drives så til UTP som er forbundet med det sentrale kontor via det første blandetrinnet.
