摘要： A number of narrow band networks are interconnected via a broad band network having a signaling protocol different from that or those of the narrow band networks. Calls between terminals associated with first and second narrow band networks are set up by the selection by a call server of a phantom trunk between the networks. This phantom trunk is used to relay the addresses of the two terminals to be connected. By recognising that two connection requests have been received at opposite ends of the same phantom trunk, a processor in the second network determines that a connection between the terminals via the broad band network is required. Selection of the phantom trunk and sending of address messages is effected via a selected one of a number of identical connection brokers coupled to the call server. The workload of the cal server is shared among the connection brokers coupled thereto.

摘要： Methods and systems for building and distributing audio packages include a database storing audio files to be played to end users in a telecommunications network. An audio package builder/export tool generates audio packages including audio segments files and index files. Audio segments files include audio segments to be played by gateways in the telecommunications network. Index files include information used by gateways to located audio segments in audio segments files. The audio packages are distributed to gateways in the telecommunications network to enable the gateways to play audio to end users.

摘要： A bit line selector switch is serially connected with a data sink for detecting high speed data transmissions, typically in the gigabit-per-second range, and a backplane having a plurality of data lines. The selector switch incorporates a selector circuit that operates in one of two modes, a first "selected", or ON, mode and a second "not selected", or OFF, mode. The selector circuit includes one, preferably differential, input. In one embodiment, a selector switch has a plurality of selector circuits thus allowing the switch to operate in both modes simultaneously. Data coupled to a differential input of the selector circuit will, when operating in the "selected" or ON mode, transmit the data to the data sink which be, for example, a memory device, processor, or the like. In the "not selected" or OFF mode, the selector circuit will pass any data received to a positive supply rail. Regardless of the mode of operation, the selector circuit presents to the coupled data lines an impedance which matches that of the data path coupling the selector circuit to the data line. The selector switch, which typically is comprised of four or less differential inputs, and thus a corresponding number of selector circuits, may be combined with other similar switches to form a multistage switch.

摘要： To estimate test coverage of procedure testing with functional specification of a procedure, predicates in functional branches in the procedure are described as logic expressions. The logic expressions of predicates are added to logic expressions of pre-condition of the procedure. Based on the logic expressions, functions of the functional specification of the procedure are generated and coverage during the procedure testing is estimated. In an embodiment, Disjunct Normal Form (DNF) is generated using short logic which omits calculation of an operand when another operand defines the result of the calculation. In another embodiment, Full Disjunct Normal Form (FDNF) is generated using three-sign logic.

摘要： A smart card terminal (910, 920, 930, 940) receives a first smart card and deducts value from the smart card. The value to be deducted is determined by a smart card holder and is relayed to a smart card terminal (910, 920, 930, 940) via a user interface on the smart card terminal. If a single slot smart card terminal is utilized for a transfer between smart cards, then the terminal deducts the value from the first smart card that is then removed from the slot. The transaction is completed when a second smart card is inserted into the slot and the value deducted from the first card is written onto the second card. If a multiple slot smart card terminal is utilized then the first smart card is inserted into a first slot and the second smart card is inserted into a second slot. A user interface guides the smart card holder(s) through the process of deducting value from the first smart card and writing it onto the second smart card. Long distance or remote transfers of value between smart cards can also be performed. A remote transfer implies two smart card terminals communicating with one another. Such communication can be telephone based or computer based and can utilize telephone networks 950 or computer data networks 960 . Smart card transfers can also be effected in a non-real-time basis meaning a first smart card can have value deducted and stored in a data network smart card server 970 for later retrieval by a second smart card.

摘要： A fiber optic switch (400) includes a fiber optic switching module (100) that receives and fixes ends (104) of optical fibers (106). The module (100) includes numerous reflective light beam deflectors (172) arranged in a V-shape which may be selected as pairs for coupling a beam of light (108) between a pair of optical fibers (106). The module (100) also produces orientation signals from each deflector (172) which indicate its orientation. A portcard (406) supplies drive signals to the module (100) for orienting at least one deflector (172). The portcard (406) also receives the orientation signals produced by that deflector (172) together with coordinates that specify an orientation for the deflector (172). The portcard (406) compares the received coordinates with the orientation signals and adjusts the drive signals supplied to the module (100) to reduce any difference between the received coordinates and the orientation signals. The switch (400) also employs optical alignment to precisely orient pairs deflectors (172) coupling a beam of light (108) between optical fibers (106).

摘要： A registration method facilitates registration of a plug-in for a Lightweight Directory Access Protocol (LDAP) directory server accessible by a client. A generic interface is provided to mediate interaction between the client and the directory server. Information is obtained concerning one or more directory entries of interest to the plug-in. This information is recorded by the generic interface in a registry such that the generic interface is enabled to call at least one method of the plug-in upon receipt of a message from the client concerning at least one respective directory entry of interest. Directory entries of interest may be identified by either their object class or distinguished name (DN). In the latter case, a wildcard syntax may be used to enable the plug-in record an interest in one or more related directory entries.

摘要： A system, device, and method for sending keep-alive messages in a communication network involves determining a reliability factor for communicating with a neighbor and setting the frequency for sending keep-alive messages to the neighbor based upon the reliability factor. The reliability factor is determined based upon the reliability of the neighbor as well as the reliability of the communication link to the neighbor. The frequency for sending keep-alive messages to the neighbor is relatively high if the reliability factor is low. The frequency for sending keep-alive messages to the neighbor is relatively low if the reliability factor is high. The frequency for sending keep-alive messages to the neighbor is dynamically adjusted based upon an updated reliability factor.

摘要： In a technique for priority forwarding, an upper layer protocol that requires priority forwarding includes a priority function that is invoked by a lower layer protocol in order to obtain the priority for a message. The upper layer protocol provides the priority function to the lower layer protocol when the upper layer protocol is installed in the protocol stack. The lower layer protocol invokes the priority function before passing a message to the upper layer protocol in order to determine a priority for the message. The lower layer protocol places the message in the appropriate queue based upon the priority indicator obtained from the upper layer protocol's priority function.
