ABSTRACT:
A personal communications unit facilitates both wired and wireless communications with a wired intercom. The personal communications unit has a headset, an intercom connection cable placeable in electrical communication with the wired headset and also placeable in electrical communication with the wired intercom, a radio transceiver which is placeable in electrical communication with the headset, and a switching circuit which is configured to place the intercom connection cable in electrical communication with the headset when the intercom connection cable is in electrical communication with the wired intercom and which is configured to place the radio transceiver in electrical communication with the headset when the intercom connection cable is not in electrical communication with the headset. Wired communications with the wire intercom are facilitated when the intercom connection cable is connected to the wired intercom and wireless communications with the wired intercom are facilitated when the intercom connection cable is disconnected from the wired intercom.
