Abstract
Abstract In a wireless terminal adapted to operate according to more than one air interface protocol, processing circuits are provided to process signals received by the terminal or to be transmitted by the terminal according to the respective protocol. One of the processing circuits is chosen to be connected to user interface equipment of the terminal to communicate with that equipment also on behalf of the other processing circuits according to a user interface equipment signal format. The other processing circuits communicate with that one processing circuit via a bus according to a bus signal format. The one processing circuit converts the bus signal format to the user interface equipment signal format and vice versa when the terminal is operating according to the protocol of any of the other processing circuits (2-4).
