Gemäß der Erfindung sind die Festteile des schnurlosen Telefons und eines normalen Telefons in einem gemeinsamen Gehäuse 1 integriert. Die elektronischen Schaltungen beider Geräteteile sind im Gehäuse untereinander verdrahtet, so daß nur eine Anschlußschnur 4 als Anschluß an das Fernsprechnetz nach außen geführt werden muß. Das Gehäuse 1 enthält unter anderem eine Ladeschaltung für den batteriebetriebenen Mobilteil 3 des schnurlosen Telefons.According to the invention are the fixed parts of the cordless phone and of a normal telephone integrated in a common housing 1. The electronic Circuits of both parts of the device are wired together in the housing so that only one connecting cord 4 led to the outside as a connection to the telephone network must become. The housing 1 contains, among other things, a charging circuit for the battery-operated Handset 3 of the cordless telephone.

Das Gehäuse 1 dient als Aufgabe für den Hörer 2 des normalen Telefons, der in gewohnter Weise mittels einer Schnur mit dem Gehäuse verbunden ist und als Auflage für den Mobilteil 3 des schnurlosen Teletons im Ladezustand.The housing 1 serves as a task for the handset 2 of the normal telephone, which is connected to the housing in the usual way by means of a cord and as Support for the handset 3 of the cordless Teleton when it is charged.

In der Figur sind auch die Funkantenne 6 des Mobilteils 3 und die Funkantenne 7 des Festteils angedeutet. Die auf dem Gehäuse 1 angedeutete Tastatur kann sich auch auf der Unterseite des Hörers 2 befinden.In the figure are also the radio antenna 6 of the mobile part 3 and the Radio antenna 7 of the fixed part indicated.
