摘要： One or more keys (101, 102, 103) can be integrally formed of a card cage and positioned to extend into the card-receiving openings of the card slots that comprise the card cage. The cards can then have key-receiving openings (112, 114, 116) that accommodate such keys. By matching the keys to particular physical and electrical functionality and compatibility attributes of a given card slot, such key-receiving openings can be similarly shaped and sized to assure that such cards cannot be inadvertently (or purposely) placed in an inappropriate card slot. In varying embodiments, such keys can be formed of a cable trough, a front panel, and a card guide seating surface.

摘要： Power supply current, sufficient to power a remote network device, is transmitted concurrently with a network data signal over a transmission line. A power-sourcing network device that can include a coupling circuit provides power and data to the remote network device. The remote network device (which can be a wireless access point) can separate the power signal from the data signal and use the power supply current to further process or retransmit the data signal. The power signal may be a low frequency relative to the frequency of the data signal, or it may be DC.

摘要： A conventional computer is coupled to an analog telephone transmission link by means of an analog/digital conversion interface adapter. Modem transmission is accomplished by performing the modulation and demodulation functions digitally in the computer's existing processor which executes programs which transfer data between the computer's memory and the interface adapter. Using the same interface adapter and existing processor, the arrangement may be used to send and receive images in the form of standard V.29 format facsimile data, to send and receive data operating as a synchronous IBM 3270 compatible terminal device, or to record and play back conventional voice transmissions rather than data to implement a telephone answering, voice message handling, and telemarketing systems.

摘要： A method and apparatus for providing roaming and hand-off support for prepaid billing for wireless prepaid services on a data network may be provided by a first-network-access device carrying on session activity of a wireless communication session with a wireless-mobile node within a first coverage area. The first-network-access device receives blocks of credits drawn from a user account having a cache of available credits for the prepaid-services. The first-network-access device periodically measures usage of the session activity in terms of a first of a plurality of measurement-method parameters. The first-network-access device debits the usage of the session activity from the blocks of credits. After entering its coverage area, the second-network-access device establishes connectivity with the wireless-mobile node. The first-network-access device tunnels to the second-network-access device the session activity and any unused credits. The second-network-access device periodically measures usage of the tunneled session activity in terms of tunneled measurement-method parameters. The second-network-access device debits the usage of the tunneled session activity from the tunneled unused credits. The second-network-access device then establishes independent network access for the session activity. The second-network-access device receives blocks of credits. The second-network-access device periodically measures the usage of the session activity in terms of another of the plurality of measurement-method parameters. The second-network-access device debits the usage of the session activity from the blocks of credits it receives. After hand-off, the first-network-access device may receive from indications to terminate session activity, to stop debiting the usage of the session activity, and/or to return unused credits.

摘要： A tool for replacing a code image in an embedded device including a control program for issuing device commands in order to replace a code image within the embedded device. A monitoring program, operating asynchronously with respect to the control program, generates event indications in response to detecting a change in an attribute associated with the embedded device. The disclosed monitoring program issues device commands and receives event indications. Separate threads of control are used for monitoring and controlling the device being upgraded, and each step of the upgrade process is abstracted as a device independent command. The disclosed system further uses a state machine to keep track of where the device is in the upgrade process.

摘要： A system and methods are shown for providing packet data serving node (PDSN) load balancing and fault tolerance. One exemplary method includes providing an access node with a plurality of packet data serving nodes and at least one system manager, receiving from a radio node on a first packet data serving node a registration request, determining that the first packet data serving node is unable to serve the registration request, and sending a packet data serving node selection request from the first packet data serving node to the system manager. The method further includes determining at the system manager a second packet data serving node to serve the registration request, and providing an address of the second packet data serving node to the first packet data serving node. The method further includes sending a registration reply message from the first packet data serving node to the radio node, where the registration reply message includes the address of the second packet data serving node.

摘要： A method and system are shown for handing off a communication stream between a mobile node and a communication endpoint from a first connection initiator to a second connection initiator while maintaining call state for the communication stream. The first connection initiator establishes a first connection to the communication endpoint in response to receiving a first connection request from the mobile node that includes a client identifier value for the mobile node. When the first connection initiator detects loss of communication with the mobile node, it sends a call-disconnect-notify (CDN) message having a cause code set to a handoff value to the connection endpoint. The connection endpoint, in response to the CDN message, stores call information for the first connection along with the mobile node's client identifier value. The first connection initiator also broadcasts a user-moved message that includes the mobile node's client identifier value and the first connection initiator's call information for the first connection. The second connection initiator, upon receiving the user-moved message, stores the first connection initiator's call information from the message along with the mobile node's client identifier value. When the second connection initiator receives a second connection request from the mobile node having the mobile node's client identifier value, it retrieves the call information from the user-moved message using the client identifier value and sends a tunnel-handoff-request message, which includes the client identifier value, to the connection endpoint. The connection endpoint retrieves its call information for the first connection using the client identifier value and sends a tunnel-handoff-response message to the second connection initiator. The second connection initiator and the connection endpoint then resume the communication stream using the call information for the first connection.

摘要： Multiple home agents for a home agent service provider network are implemented in a single computing platform in software as multiple virtual home agents. Each home agent is assigned or dedicated to a single virtual private network. Any number of home agents can be realized in the computing platform by multiple instantiations of a home agent program or code, and by providing unique IP addresses for each instantiation. Each home agent runs independently, and is independently configured and managed by the subscriber of the virtual private network service, freeing the service provider of having to manage and supervise low level processing tasks and customization features that the subscribers may want. In a representative embodiment, the computing platform comprises a router having a general purpose-computing platform.

摘要： A chip component assembly is provided that includes a plurality of chip components each having respective first and second terminal elements, the first terminal elements being joined to corresponding solder pads on a printed circuit board, the solder pads being in communication with electronic circuitry of the printed circuit board, and the second terminal elements being joined together by an array ground plane of a grounding device. The grounding device additionally includes a ground path structure which physically and electrically connects the array ground plane, and thus the chip components, to a ground pad located on the printed circuit board so as to provide a ground path from the chip components. Preferably, the array ground plane additionally includes a plurality of resilient contact elements which provide for substantial and continuous contact between the array ground plane and an ancillary ground plane, such as the top cover of a PC card. The grounding device serves to foreclose electrostatic discharge or EMI by the chip components and in some applications further serves to direct undesirable noise to ground. The relatively small size of the grounding device permits the use of a relatively smaller ground pad on the printed circuit board, thereby conserving valuable printed circuit board surface area. Finally, the ground path structure is configured for automated attachment to the chip components, and the chip component assembly thus formed is well suited for installation on the printed circuit board by pick-and-place manufacturing techniques.
