Abstract:
In a mobile satellite system, a mobile communication system includes a user interface system, an antenna system, a transceiver system, a logic and signaling system. The logic and signaling system provides a roam function permitting the mobile communication system to roam between the mobile satellite system and a terrestrial based communication system responsive to the user selection of a primary service and an alternate service. The mobile communication system also includes a digital terminal equipment unit initiating setup and release for a data call, and a facsimile interface unit initiating setup and release for a facsimile call. The facsimile interface unit generates a line control packet responsive to a line state transition indicating transmission of information associated with a new line state over a communication channel. The facsimile interface unit includes a look ahead buffer to perform early line control packet detection by looking ahead a predetermined time interval into a received satellite data stream and identifying a valid idle line control packet.
