Abstract

Bei dem erfindungsgemässen Fernsprechgerät werden Fernsprech-Betriebssignale (Klingelsignal, Gebühreneinheitensignale und Anrufer-Kennungen) und Audiosignale gemeinsam durch einen integrierten Schaltkreis (8) verarbeitet. Dazu ist es notwendig, eine Signalpegelanpassung der einzelnen Signale durchzuführen. Da die Fernsprechsignale gemeinsam durch einen Chip, vorzugsweise durch einen digitalen Signalprozessor (DSP), verarbeitet werden, kann der bisher erforderliche Aufwand an diskreten Bauelementen reduziert werden.
