Abstract: The present invention is directed to a system and method for implementing an intelligent redial system. A method for storing redial data for a connection between a user phone system and a remote phone system may include establishing a connection with the remote phone system by the user phone system. A timer is started in response to the established connection. At least one digit is dialed by a user and corresponding time data of the timer with the dialed digit is monitored. The monitored digit and corresponding time data is stored. The stored monitored digit and corresponding time data are suitable for performing a redial.

Abstract: In an enhanced 911 (E911) response system, a callback monitor including a microphone and a speaker is connected to a telephone. When a caller dials 911 from the telephone, upon the telephone going on-hook, the callback monitor is activated to allow a 911 operator who calls back to detect sounds from the location of the caller's telephone without that phone ringing or being taken off hook. The callback monitor includes a timer; when the timer expires, the monitoring ends. In alternative embodiments, the timer can be extended.

Abstract: A broad band digital radio receiver for multicarrier signals employs a quadrature demodulator to directly shift the radiofrequency signal in a base band. A local oscillator has frequency f0 placed at the center of the radiofrequency BW band, so channel pairs, symmetric versus f0, are superimposed in the lower base half-band. Base band equivocation is then solved by numeric-type second orthogonal demodulators, which supply pairs of twice-demodulated signals that can be grouped in four equation systems in four unknown values consisting of in-phase and quadrature components of the two channels of each pair. Subsequent reconstruction networks solve the relevant systems and give the two components of each single channel for each pair. One network in the receiver measures amplitude and phase dissymmetries in the two branches of the analog demodulator and supplies four corresponding digital coefficients to the reconstruction network, which can then counterbalance at output the effects of dissymmetry.

Abstract: An IP Telephony Emergency Connections (ITEC) system and method that determines the precise origin of an emergency call and routes the call to the proper Public Service Answering Point (PSAP). A source-based routing mechanism is provided in an IP telephony type network, such as a VoIP or IP over LAN/ATM. Emergency calls are routed to the correct PSAP jurisdiction. Each server/switch may include the mechanism such that the IP Telephony network can identify an E911 connection and egress to a public network at a point closest to the emergency call point of origin. Whenever an emergency number call is made, the call's origin is determined during call setup establishment. Every port or end user jack in the network is assigned a Source Group Index (SGI), which is a number or index representing each PSAP jurisdiction in the network. All ports/jacks within the same PSAP jurisdiction are assigned the same SGI. Users may be in different areas of multiple PSAP jurisdictions.

Abstract: In an isochronous telecommunications system sending packets over two routes in a network, a server of the network compares overall transmission delay between the routes. If the new route is faster, a server buffers cells on the new route until the last cell on the old route is delivered. Then the first cell from the new route is delivered at the old delay and subsequent new route cells are delivered with the same delay. If the old route is faster, a server identifies the type of transmission; if it is voice, a signal is inserted to alert the receiver of delay, and if the transmission is video, the system resends the last frame from the old route until frames from the new route arrive.

Abstract: A telecommunications system includes a network (101); a plurality of endpoints (102a, 102b) operably coupled to the network; a gatekeeper and a database engine, typically located in a gatekeeper server (108), for downloading database information such as a corporate directory, to the endpoints. The gatekeeper server and the endpoints further include load monitors (2002) for monitoring device performance. If the load is higher than a threshold, the gatekeeper will not provide a requested database information. The endpoint then requests the information from another endpoint.

Abstract: A system and method for accessing complex computer based systems initiates a trace and debug session via IP causing the resulting output to be stored in a designated remote server on the Internet which can accept large amounts of information. The trace and debug information subsequently can be accessed from any engineering workstation or personal computer from any other location via the Internet. The invention permits the trace sessions to run independent of any local access and permits several technical people in different locations to access the remote storage server simultaneously or independently.

Abstract: A public health threat surveillance system. Remote sensing devices, each including a sensor collect information related to the presence of hazardous agents, e.g., for detecting a bio-toxin. The sensing devices format collected information in a wireless message protocol, e.g., short message service (SMS) and send formatted information. The remote sensing devices may include any adapted (i.e., with a sensor) typical wireless communications device, e.g., a cell phone, a wireless enabled PDA, notebook computer or tablet computer. A health alert processing center (HAPC) receives wireless protocol messages with the hazardous agent information. The HAPC aggregates data from collected SMS messages and selectively distributes response information, e.g., to a higher level HAPC and/or selected connected wireless devices.

Abstract: A distributed communication system that is capable of providing emergency call diversion during an event such as a power outage, network or sub-network failure, site closure, or the like, allows devices within the system affected by the event to rapidly inform one another that it is necessary to enter a call diversion state or mode during the duration of the outage. In this manner, calls may be diverted from different points within the network, or with different diversion behaviors as necessary.

Abstract: A communications network connected to a plurality of communications lines and method of managing connections to the network. The presence of an interface connection to a communications line is detected and initialized for signaling. First, the interface connection is initialized for a first signaling protocol, e.g., CCS. If initialization is successful, the connection uses that first signaling protocol. If not, the interface connection is initialized using a second signaling protocol, e.g., CAS. If initialization to the second protocol is successful, the connection uses that second signaling protocol. Otherwise an error message is returned.

Abstract: To compensate for polarization mode dispersion (PMD) induced distortion in an optical signal, an optical pulse is split into two orthogonally polarized pulses. A polarization controller selectively aligns the arbitrarily oriented first and second principal states of polarization of the PMD pulses to match fixed orientations of predetermined first and second principal states of polarization of a beam splitter. The PMD pulses are then coupled to a Mach-Zender interferometer that measures the differential delay between them and selectively compensates for the measured differential delay. An optical combiner combines output the compensator PMP pulses to generate a combined output optical signal.
