Abstract
A device of the DECT type is disclosed which includes a base station connected to the telephone network transmitting an identification information signal which defines a calling user. This station is formed by a processor assembly, a memory containing an execution program and a random-access memory. The device also includes at least one handset formed by, inter alia, a display, a processor assembly notably intended to control said display. For transmitting the identification information, broadcasting means are provided for broadcasting to all the handsets by using message transmission means for transmitting messages of the service provided by said DECT standard.
Claims19
A telephony device comprising:
- a base station connected to a telephone network, said base station receiving a communication signal and an identification signal of a caller from said telephone network;
- a plurality of handsets which are connectable to said base station via radio links for receiving said communication signal and said identification signal, wherein said communication signal is provided on a first one of said radio links and said identification signal is provided on a second one of said radio links;
- said second one of said radio links being different than said first one of said radio links so that transmission of said identification signal does not affect availability of said first one of said radio links for transmission of said communication signal;
- wherein said base station broadcasts said identification signal to all of said plurality of handsets.
A telephony device comprising:
- a base station connected to a telephone network, said base station receiving communication signals and identification signals from said telephone network;
