Abstract: A system, method, apparatus, means, and computer program code for determining a location of a device connected to a network. According to some embodiments of the present invention, a device, such as an IP enabled or compliant telephone, may receive, detect, or otherwise actively or passively determine a location identifier. The location identifier may be associated with a geographic location of the device. The device may then provide data indicative of the location identifier to another device, such as a network manager device, server, computer, etc. In some embodiments, the device may determine its geographic location after receiving a request for data indicative of its geographic location. In other embodiments, the device may provide data indicative of its geographic location each time it receives, detects or otherwise determines its geographic location.

Abstract: A method, apparatus and communication system for efficiently and economically supporting a multipoint videoconference call is described. The multimedia conference unit determines which communication unit is a dominant communication unit, with the other communication units being thus determined to be subordinate communication units. The multimedia conference unit then commands the subordinate communication units to suppress a video portion of their respective signals, such that the digital signal processing analysis by the multimedia conference unit required to support the multipoint conference is reduced and network bandwidth used is minimized.

Abstract: The present method for predictive caching operation determines a time-based pattern of a high-access period for a web page, and pre-fetches the web page into a cache before the high access period begins. A table is generated where the table comprises a URL, a time of last access and a time stamp of the pre-fetched web page. When a request for a web page is made, the requested web page's URL and time stamp are checked with the URL and time stamp listed in the table to determine whether any modification has been made. The web page which has been modified is downloaded into the cache.

Abstract: A bandwidth adjustment server (BWAS) (109) is provided which monitors system bandwidth usage, sends requests to terminals (102A, 102B and/or 106), to identify their coding capabilities, and directs each of the terminals to adjust their coding algorithms based on system bandwidth usage. If system bandwidth usage is high, the BWAS (109) requires the terminals to employ a less bandwidth intensive coding algorithm; similarly, when system bandwidth usage is low, the BWAS (109) will allow the terminals to employ higher bandwidth use coding algorithms.

Abstract: An improved system and method for loading and linking a dynamic link library (DLL) for use of its entities by an application program. During design, implementation, and production implicit linkage is assumed. Upon load and execution by the computer operating system, explicit linking is assumed resulting in unresolved external references. During execution, the application program invokes DLL loading and linking routines to resolve these external references within the application program's memory space. The application program continues execution and seamlessly invokes DLL entities.

Abstract: A Carrier Identification Code (CIC) aware private communications network. International calls are placed with a CIC from a station at an originating server and routed over a private network to a connected public network gateway switch located in another country for a far-end hop-off. The public network gateway switch includes a CIC cross reference table with corresponding local CICs. The public network gateway switch replaces the original CIC with a corresponding local CIC from the cross reference table. Then, the call egresses from the public network gateway switch to a corresponding selected carrier network and connects to the called party on the public communications network.

Abstract: Within a network environment, redundant capabilities for exchanging call-processing signals enhance reliability of telephony support for telephony endpoint devices. A data network, such as a telephony-over-local area network, provides primary support for the telephony endpoint devices, which may be telephony-enabled computers or Internet Protocol telephones. A second network has a first mode in which it is inactive with respect to telephony traffic to the telephony endpoint devices, but has a second mode in which call-processing signals are routed through the second network in response to a determination that the data network is disabled. As a result, telephone features such as call deflection may be continued when the primary support is disabled.

Abstract: A jitter buffer controller (110) allows the depth of the jitter buffer (113) to be adjusted dynamically according to the varying jitter of the current sequence. The jitter buffer controller (110) maintains a cache (109) of previous jitter values. This cache contains exponentially averaged values that represent the long-term behavior of specific destination's jitter characteristics, i.e., a jitter characteristic memory. These values are used to initialize the jitter buffer's depth. The jitter cache prevents the buffer's depth from being initialized with an arbitrary value that disregards the specific destination's jitter characteristics.

The apparatus of the invention detects an emergency number, assigns the call priority, and uses the port/device number to determine the ELIN/callback number and properly transmit the ELIN/callback number over a private network for far-end hop-off to the public network PSAP.

Abstract: A display format for a distributed system and method using a catalog definition language (CDL) based integrated trace analysis (iTAS) application for decoding telecommunication tracer information originating from any telecommunication network element and utilizing any Industry standard or proprietary telecommunication protocol using a browser-based graphical user interface (GUI). The display format of the browser-based graphical user interface (GUI) includes a common display page having three panes in which to display a tree view of trace events, a view of the decoded trace data, and a view of the original trace. The view within all three panes can be synchronized based on the selection of an event from the tree view pane. Additional panes on the common display page are provided for controlling the display, searching and filtering the contents of the three panes, and displaying the progress of decoding.

Abstract: A virtual private communications network (VPCN) and method of managing calls on the network. Communications devices are networked together over a private communications network. Each VPCN communications device has a unique private network identification (ID) code and can be contacted by dialing its respective ID. At least one of the VPCN communications devices is a wireless communications device, e.g., a cell phone, connected through a public wireless network to the private communications network. Calls to and from each such wireless device pass through the private communications network.

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 telecommunications server (12) includes a timed recall request unit (202) coupled to a timer (200). The timed recall request unit (202) interfaces to the call park service (100) and/or the call hold service (101). When a request for a call park or call hold is made, the user is given the option of electing timed recall or no recall. If a timed recall is desired, the timed recall request unit (202) is accessed to permit the user to either accept a default length of time or to input a desired length of time. If the user manually retrieves the held or parked call prior to expiration of the timer, the timer (200) is reset.
