Combined mobile and cordless telephone

摘要

The telephone includes an additional transmitter and receiver in the telephone module of the mobile telephone, along with a change-over switch. The additional receiver receives only the frequency (B) for the mobile telephone and is on constant standby. For an incoming call from the mobile network, this receiver gives a signal to the change-over switch that switches off the transmitter and the amplifier (A) for the radio telephone and switches on the transmitter and the amplifier (B) for the mobile telephone. This changeover is reversed when the conversation ends.
