Claims

1. In a cellular interface unit for coupling a land-type telephone instrument to a cellular radio system, which interface unit comprises interface means for coupling the land-type telephone instrument to a cellular radio transceiver for providing the capability of using the land-type telephone instrument for making or receiving calls over a cellular radio system, the improvement comprising:

premises land-line wiring connection means for connecting said interface means to premises land-line wiring of a landline telephone network, which premises land-line wiring has a first wireline thereof capable of being connected to the landline telephone network, and a second wireline thereof capable of being connected to the landline telephone network, which premises land-line wiring has tip and ring terminals for each of the first and second wirelines;

said means for connecting comprising means for coupling said interface means to tip and ring terminals of a premises second wireline.

2. In a cellular interface unit for coupling a land-type telephone instrument to a cellular radio system, which interface unit comprises interface means for coupling the land-type telephone instrument to a cellular radio transceiver for providing the capability of using the land-type telephone instrument for making or receiving calls over a cellular radio system, the improvement comprising:

premises land-line wiring of a landline telephone network, said premises land-line wiring having a first wireline thereof capable of being connected to the landline telephone network, and a second wireline thereof capable of being connected to the landline telephone network, each of said first and second wirelines having tip and ring terminals;

said cellular interface unit comprising premises land-line wiring connection means for connecting said interface means to one of said first and second wirelines of said premises land-line wiring;

said premises land-line wiring means comprising means coupling said interface means to said tip and ring terminals of said one of said first and second wirelines of said premises land-line wiring.
