Abstract

A communication system including a first transceiver adapted to communicate with a first network; a second transceiver adapted to communicate with a second network; and an interface to a third network a switching network is included for routing signals between the first transceiver and the interface in a first mode of operation and for routing signals between the first transceiver and the second transceiver in a second mode of operation. A central processing unit is included for switching the controller between the first mode and the second mode in response to an input signal. In the illustrative embodiment, the first network is a cordless telephone network, the second network is a wireless cellular network and the third network is a public switched telephone network. In the illustrative application, the inventive system is implemented as a dual mode base station adapted for routing signals between a cordless transceiver and a public switched telephone network in a first mode of operation and routing signals between said cordless transceiver and a wireless cellular network in a second mode of operation. In the illustrative embodiment, the inventive dual mode base station includes a cordless transceiver; a wireless transceiver; an interface to a public switched telephone network; a switching network for routing signals between said cordless transceiver and said interface in a first mode of operation and between said cordless transceiver and said wireless transceiver in a second mode of operation; and a central processing unit for switching the controller between the first mode and the second mode in response to an input signal.

Claims
