ABSTRACT:
A device for supporting multiple line configurations in a Fixed Wireless Loop (FWL) application includes a hand-held transceiver supporting wireless communications. The device also includes a cradle disposed on or in the building for receiving the hand-held transceiver and terminating a primary telecommunications line having at least one primary telephone connected thereto. The cradle further terminates a secondary telecommunications line, different from the primary telecommunications line, having at least one secondary telephone connected thereto. Still further, the cradle includes a spring-loaded switch integrally formed therein, wherein when the hand-held transceiver is in the cradle, the switch is biased to break contact between the primary telecommunications line and the secondary telecommunications line. When the hand-held transceiver is removed from the cradle, the switch is biased to connect the primary telecommunications line with the secondary telecommunications line so as to permit users of the primary telecommunications line to continue to receive and place calls when the hand-held transceiver is removed from the cradle.
