1. An interface for alternately coupling at least one land-type telephone or telephone-like instrument to a first land-line connected to a telephone central office of a land-line telephone system at a premises, and to a second land-line that is not directly connected to the telephone central office of a land-line telephone system at the same premises, comprising:
- switching means for alternately connecting at least one land-type telephone or telephone-like instrument to one of a first land-line and a second land-line;
said switching means connecting at least one land-type telephone or telephone-like instrument to a first land-line when at least one of an incoming call and an outgoing call is to be established over the land-line telephone system;
radio-coupling means for coupling at least one land-type telephone or telephone-like instrument to a radio transceiver so that the at least one land-type telephone or telephone-like instrument may communicate using a radio system;
said radio-coupling means being connected to a second land-line, said switching means connecting the at least one land-type telephone or telephone-like instrument to the second land-line when at least one of an incoming call and an outgoing call is to be established over the land-line telephone system; and
testing means for testing the first and second land-lines to ensure that the first land-line is actively and directly connected to a telephone central office of a land-line telephone system, and that the second land-line is not directly connected to the telephone central office of a land-line telephone system.
