Description
PATENTKRAV 1. Forstærkerkobling, der er indkoblet mellem en fastnettelefon og et hovedsæt, kendetegnet ved, at forstærkerkoblingen er udformet med brugerspecifikke overføringskarakteristikker. 2. Forstærkerkobling ifølge krav 1, kendetegnet ved, at den brugerspecifikke overføringskarakteristik er Telstra Specifikation TT4. 3. Forstærkerkobling ifølge krav 1, kendetegnet ved, at den brugerspecifikke overføringskarakteristik dæmper signaler over ca. 1 kHz. 4. Forstærkerkobling ifølge krav 1, kendetegnet ved, at den brugerspecifikke overføringskarakteristik dæmper signaler i frekvensområdet ca. 1-1,5 KHz, medens signalerne forstærkes over ca. 2 kHz. 5. Forstærkerkobling ifølge krav 1-4, kendetegnet ved, at den indeholder en automatisk forstærkningsregulering af signaler, der tilføres hovedsættet, idet forstærkningen indstilles på grundlag af et fra fastnettelefonen detekteret signal. 6. Forstærkerkobling ifølge krav 1 - 5, kendetegnet ved, at de brugerspecifikke overføringskarakteristikker indeholder en maksimal tilladelig amplitude af det til hovedsættet overførte signal i hele det overførte frekvensspektrum. 7. Forstærkerkobling ifølge krav 1 - 6, kendetegnet ved, at fastnettelefonen og forstærkerkoblingen er sammenkoblet med to ledninger, og at der mellem ledningerne er indkoblet en afbryder, såsom en bypass kobling. 8. Forstærkerkobling ifølge krav 1 - 7, kendetegnet ved, at de brugerspecifikke overføringskarakteristikker er udformet i forstærkerkoblingen som faste kredsløb, hvor hvert kredsløb kan indkobles ved hjælp af switche. 9. Forstærkerkobling ifølge krav 1 - 8, kendetegnet ved, at der til forstærkerkoblingen er tilkoblet en PC, der er indrettet til at overføre de brugerspecifikke overføringskarakteristikker. 10. Forstærkerkobling ifølge krav 9, kendetegnet ved, at tilkoblingen af PC'en sker via en USB port. 11. Forstærkerkobling ifølge krav 9, kendetegnet ved, at tilkoblingen af PC'en til forstærkerkoblingen er trådløs.
