Abstract: A telephone handset has a flat satellite antenna mounted thereon, the antenna being movable between a first position, in which the antenna is parallel to and contacting a main portion of the handset, and a second position, in which the satellite antenna faces in generally the same direction as a top surface of the main portion. A cover portion is mounted on a side of the main portion opposite to the satellite antenna and movable between an open position and a closed position to provide, with the satellite antenna, a compact three-fold configuration.

Abstract: A multi-media network bus (MMN-Bus) and Controller (MMNC) serve as a distribution medium between a single high-speed network and multiple user network interfaces (UNIs). The MMNC allocates multiple isochronous channels and packet channels for distribution to the users over the MMN-Bus. The MMNC sends information in standard time segments or master cycles. Following transmission of a start signal, a series of control blocks is sent. The first type of control block is used for communication from the MMNC to each UNI. The second type of control block is used for transmissions from each UNI to the MMNC. Both types of control blocks are used for call setup, call acknowledgement, channel allocation, call end and packet data request. Following transmission of both sets of control blocks, a signal is sent to indicate the beginning of a sequence of isochronous transfers. Each UNI tracks the number of signals, identifying those signals which it should either receive or transmit.

Abstract: A method and system for call set-up and channel resource allocation between a plurality of parties in a multi-media conference call that consists of receiving notice that a Sender (the initiator of the conference) wants to commence a video conference. At that point, the number of channels required by the proposed call is determined. Subsequently, each requested participant is identified as available, busy, or no answer. If the receiver is available and sufficient channels are available, the call is set-up and the present members of the conference are notified of what channel each should transmit on and what channel(s) to listen to for the other participants. As each receiver is added, the Sender may conference with the present Receiver. If it is decided at this point, that the receiver will not participate in the conference, the call to that receiver may be terminated, and the procedure continues for other receivers until the full conference is set up. Individuals may leave the conference at any time.

Abstract: The invention discloses a single competitor arbitration code for determining if only one communications module is contending for a communication data bus and gives that module access within two bus clock cycles. An aggregate code is generated by using the true and complement of the module ID. A check code for each bit is determined by adding the aggregate code for the bit and its adjacent bit. If the check code contains any zeros, then more than one module is contending for the bus. The 10-bit single arbitration scheme allows for error detection and correction on a 32-bit data bus.
