A system is provided that includes a network entity, such as a packet data switching node (PDSN), and a terminal capable of establishing a data-link connection with the network entity, such as after setting up a physical-layer connection with the network entity. After the data-link connection is established, the network entity and the terminal can configure a network-layer protocol such that data formatted in accordance with the network-layer protocol can thereafter be sent between the terminal and the network entity over the data-link connection. Then, during configuration of the network-layer protocol, the terminal can discover at least one service available to the terminal by receiving, from the network entity, a listing of the at least one available service. The listing of each available service includes an address of a provider of the available service and a port number and/or pathname for accessing the service at the provider.

Methods and systems are provided for performing protocol conversions in an environment including a work machine having one or more modules coupled to one or more data links. Such methods and systems may leverage one or more gateways to perform tunneling, translating, and bridging operations. Tunneling processes may include receiving a message from a source module in a first protocol, encapsulating the message within transmission units of a second protocol, and transmitting the encapsulated message via the second protocol. Translating processes may include receiving, by the gateway, a message in a first data link protocol including a parameter identifier. The gateway may match the parameter identifier with a parameter identifier included in a translation table and scale associated parameter data using a scale factor corresponding to a second data link protocol. The gateway may then provide the scaled parameter data to a module using the second data link protocol.

A test apparatus having a base which performs a plurality of tests for different analytes in body fluids. A portable tester, such as a glucose meter, is detachably mounted to the base and provides a convenient and ergonomic hand-held instrument which a diabetic may carry to frequently monitor blood glucose levels. When mounted or docked to the base, the portable tester is data linked to the base. The invention provides a communications network among the base, the portable tester and another device such as a PC.

A bus permits the number of active serial data lanes of a data link to be re-negotiated in response to changes in bus bandwidth requirements. In one embodiment, one of the bus interfaces triggers a re-negotiation of link width and places a constraint on link width during the re-negotiation.

The invention increases performance of HTTP over long-latency links by pre-fetching objects concurrently via aggregated and flow-controlled channels. An agent and gateway together assist a Web browser in fetching HTTP contents faster from Internet Web sites over long-latency data links. The gateway and the agent coordinate the fetching of selective embedded objects in such a way that an object is ready and available on a host platform before the resident browser requires it. The seemingly instantaneous availability of objects to a browser enables it to complete processing the object to request the next object without much wait. Without this instantaneous availability of an embedded object, a browser waits for its request and the corresponding response to traverse a long delay link.

A method and apparatus provides OFDM signal compression for transfer over serial data links in a base transceiver system (BTS) of a wireless communication network. For the uplink, an RF unit of the BTS applies OFDM cyclic prefix removal and OFDM frequency transformation of the baseband signal samples followed by frequency domain compression of the baseband signal samples, resulting from analog to digital conversion of received analog signals followed by digital downconversion, forming compressed coefficients. After transfer over the serial data link, the baseband processor applies frequency domain decompression to the compressed coefficients prior to further signal processing. For the downlink, the RF unit performs frequency domain decompression of the compressed coefficients and applies OFDM inverse frequency transformation of the decompressed coefficients and OFDM cyclic prefix insertion prior to digital upconversion and digital to analog conversion, generating the analog signal for transmission over the antenna.

A method for processing a financial transaction using an interchange network computer coupled to a database is described.

The method includes receiving, at the interchange network computer, a linked account data file for the first transaction card. The data file includes data associating the first card with a first secondary account and data linking the first secondary account to a first primary account. The method also includes storing the data file within the database and receiving a first authorization request message for the first transaction. The method also includes determining, based on data included within the first authorization request message, that the first card is associated with the first secondary account and processing the first authorization request message by applying at least one processing code associated with the first primary account to the first transaction.

Two data storage systems are interconnected by a data link for remote mirroring of data. Each volume of data is configured as local, primary in a remotely mirrored volume pair, or secondary in a remotely mirrored volume pair. Normally, a host computer directly accesses either a local or a primary volume, and data written to a primary volume is automatically sent over the link to a corresponding secondary volume. Each remotely mirrored volume pair can operate in a selected synchronization mode including synchronous, semi-synchronous, adaptive copy-remote write pending, and adaptive copy-disk. Direct write access to a secondary volume is denied if a “sync required” attribute is set for the volume and the volume is not synchronized.

Transmitters, receivers, and coding schemes to increase data rate and decrease bit error rate of an optical data link are disclosed. Data is transmitted across the link with a less than nominal bit error rate (BER), by encoding the data using a forward error correction (FEC) code or by requesting retransmission of transmitted packets in error. Data is transmitted at a speed that introduces errors at a rate that is in excess of the nominal BER but that may be corrected using the FEC code or retransmission so that the data may be received with less than the nominal BER. The data rate is increased as the link operating speed is increased beyond the overhead required by the FEC codes or retransmission. High speed FEC encoders and decoders facilitating such transmission are disclosed.

A method and apparatus provide signal compression for transfer over serial data links in a base transceiver system (BTS) of a wireless communication network. For the uplink, an RF unit of the BTS applies frequency domain compression of baseband signal samples, resulting from analog to digital conversion of received analog signals followed by digital downconversion, forming compressed coefficients. After transfer over the serial data link, the baseband processor then applies frequency domain decompression to the compressed coefficients prior to normal signal processing. For the downlink, the baseband processor applies frequency domain compression of baseband signal samples and transfers the compressed coefficients to the RF unit. The RF unit applies frequency domain decompression to the compressed coefficients prior to digital upconversion and digital to analog conversion, generating the analog signal for transmission over the antenna.
