摘要： An arrangement for providing synchronization between a number of overlapping area access points within a wireless LAN utilizes an Ethernet cable connection to transmit synchronization signals from a centralized hub/switch to each of the access points connected to the cable. The synchronization signal takes the form of a direct sequence spread spectrum (DS-SS) signal. At each access point, a filter is used to recover the synchronization signal, allowing for the group of access points to share a common beacon signal and allowing frequency re-use among the access points.

摘要： A method and apparatus for increasing the data rate and providing antenna diversity using multiple transmit antennas is disclosed. A set of bits of a digital signal are used to generate a codeword. Codewords are provided according to a channel code. Delay elements may be provided in antenna output channels, or with suitable code construction delay may be omitted. n signals represent n symbols of a codeword are transmitted with n different transmit antennas. At the receiver MSLE or other decoding is used to decode the noisy received sequence. The parallel transmission and channel coding enables an increase the data rate over previous techniques, and recovery even under fading conditions. The channel coding may be concatenated with error correction codes under appropriate conditions.

摘要： A method and apparatus for enabling providers of PSTN toll free services to stagger simultaneous transmission of call setup signaling messages into an IP based teleconference bridge, supported by a VoIP network, by suspending a subset of calls and placing them on hold while placing other calls to be connected to the conference bridge are disclosed. The PSTN network can stagger calls by limiting the number of call setup signaling messages to be sent to the VoIP network within a predefined period of time interval and spread all the calls over multiple of such predefined periods. Prerecorded announcements or music can be played while the calls that have been placed on hold are in queue.

摘要： The invention describes a method for hardening a security mechanism against physical intrusion and substitution attacks. A user establishes a connection between a network peripheral device and a network via a security mechanism. The security mechanism includes read only memory (ROM) that contains code that initiates operation of the mechanism and performs authentication functions. A persistent memory contains configuration information. A volatile memory stores user and device identification information that remains valid only for a given session and is erased thereafter to prevent a future security breach. A tamper-evident enclosure surrounds the memory elements, which if breached, becomes readily apparent to the user.

摘要： A telephone network voting system receives telephone ballots cast by voters by dialing a telephone number. The telephone number is dialed by voters spread over a large geographic area. The voting calls are routed to points of presence local to or otherwise identified with the caller by using the caller's ANI or other originating number identification. The points of presence then accumulate votes and periodically forward tallies to a centralized location over a data network. Instructions may be transmitted from the centralized location to the points of presence.

摘要： A method and apparatus for collecting and processing line performance data transmitted over cables, e.g., Y-cables, is disclosed. The present invention applies a method based on specific performance measurements, specific measurement time intervals, and compare results from different measurement time intervals to produce a “signature” that indicates deteriorating performance of a particular Y-cable. Once a “signature” is detected, the method will proactively and automatically generate a trouble ticket to trigger the dispatch maintenance staffs to service the cable, e.g., to perform the replacement of the Y-cable in question, thus completing the predictive maintenance process. A trouble ticket is a record used to report and manage the resolution of network related problems.

摘要： A method allows access to a set of secure databases and database applications over an untrusted network without replicating the secure database. The method involves authenticating a user using a first authentication application. When the user is verified, then the user's credentials are directed to a second authentication application associated with a secure database based on a first set of user settings retrieved for the user. The second authentication application, based on a second set of user settings, grants the user access to the secure database and database applications associated with the secure database.

摘要： A “customized” caller ID service platform is utilized within a telecommunications network (which may be the PSTN, an IP network, or any other network for supporting voice communication) to allow for the caller ID information transmitted to a called party to be tailored to the specific called party. A database within the platform is configured to store a listing of registered subscribers and a set of “pre-defined called numbers” associated with each subscriber. For each listed number, the subscriber provides the specific customized information (for example, an account number) that is to be transmitted to that specific called number as the caller ID information. A registered subscriber is able to gain access to the platform and modify the entries as need be.
