Abstract: A terminal adapter, along with a value added network, is disclosed that interworks a plurality of terminals with a processing host to accomplish transaction processing. The terminals can use different protocols and typically incorporate card readers for completing financial or other types of transactions typically involving credit, debit, ATM or similar cards. The terminal adapter provides reliable and secure communication using a network based in part on the Internet as a primary form of communication. The terminal adapter also provides a secondary communication path in the event of a failure of the primary communication path, as well as automatic recognition of different terminal protocols, various security functions, error detection, and other network administration functions to ensure a flexible system and efficient transaction processing system.

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: Methods for accurate transmission of ELIN/callback number from an emergency caller calling from behind a PBX/MLTS include assigning a port equipment number to each device/trunk of the PBX/MLTS and associating ports/devices with ELINs and callback numbers. 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.

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.

The categories may be arranged as a list or as thumbnails and typically includes a length of time for each category; a time during the conference when the associated clip was recorded; and a media type. The categories are clickable and allow the associated clip to be played or displayed as recorded. In addition, in certain embodiments, a voice recognition transcription of audio clips may be provided.

Abstract: A telecommunication system includes a source private branch exchange (12) that transmits telephone calls from a source to a destination private branch exchange (26) over a public switched telephone network (18). As an alternative to transmitting the calls over the public switched telephone network, the private branch exchange is coupled to a telephony Internet server 30 that can transmit telephone calls over a global wide area computer network such as the Internet (32). The private branch exchange (12) queries the destination private branch exchange (26) to determine if it similarly coupled to a telephony Internet server. If so, the bandwidth used by the telephony Internet server will allow the transmission of the telephone call, the call is routed over the Internet (32) to the intended recipient.

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.

Abstract: A variable length frame transmission method making it possible to accurately and easily establish synchronism at the receiver side without redundancy of system under an environment in which a code error easily occurs. In a transmitter, a variable length frame division section 1 divides a variable length frame f into code strings f1 and f2 having a length ratio of 1:1. A first synchronization flag addition section 3-1 adds a synchronization flag S1 to the head of the code string f1 and a second synchronization flag addition section 3-2 adds a synchronization flag S2 to the head of the code string f2. The synchronization flags have contents different from each other, but they have the same length. Code strings having synchronization flags are multiplexed by a changeover switch 4 and formed into a variable length frame. A series of variable length frames obtained from the changeover switch 4 are transmitted to a receiver as serial data.

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 base station 422 of a second system performs communication using a frequency adjacent to a frequency employed by communication between a base station 412 and a mobile station 414 of a first system. When the mobile station 414 is close to the base station 422, the communication of the base station 422 undergoes interference by the leakage power of the mobile station 414. To avoid the interference, the transmission is halted of the mobile station 414 of the first system, which provides the interference by the leakage power.

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: An SIP-H.323 gateway (210) is provided, which functions as a multi-alias H.323 endpoint (204) with one alias representing one SIP agent (206). The SIP-H.323 gateway (210) processes the call signaling conversions and stores and passes media port information to the signaling parties, so that the existence of SIP agents (206) is transparent to the H.323 endpoints (204) and the features are transparently available to the H.323 endpoints.

Abstract: An exclusive OR of outputs from a plurality of shift stages of an M-series generator is formed, thereby obtaining an M-series which has a desired delay, which in an example is a three bit delay with respect to the output code from the generator. Similarly, outputs from a plurality of shift stages are combined and an exclusive OR thereof is formed to provide another delayed M-series. An exclusive OR of each output from the simultaneously delayed code generator and an output from another M-series generator is formed, thus simultaneously obtaining a plurality of Gold code series.

Abstract: An H.323 client terminal (102) according to an embodiment of the invention employs primary and secondary H.323 control units or state machines (110a, 110b). The primary control unit (110a) sends signaling messages to a primary gatekeeper (108a) and triggers the secondary control unit (110b) to send a message with an appropriate correlation identifier directly to a second client terminal. The primary control unit (110a) establishes a call per standard H.323 protocols. The secondary control unit (110b) also establishes a direct signaling connection to the second client terminal as back up. However, no media channels are established for this backup signaling. The secondary control unit (110b) checks the status of the call with the primary control unit (110a). If the call signaling on the primary control unit (110a) is proceeding normally, no further action is taken.

Abstract: A fiber-optic cable includes a conductive coating formed around an optical fiber. The conductive coating may be in the shape of a band or ring located at a terminal end of the fiber, or may extend along the entire length of the fiber or a portion thereof. For protection purposes, the fiber is covered with a buffer made from a plastic or polymer. The fiber-optic cable may be attached to a plug or receptacle of a connector. Preferably, the cable is attached to the plug. Under these circumstances, the receptacle would be equipped with a verification circuit for confirming that the plug has been properly installed into the receptacle housing. An electronic device may be used to alert a user as to whether proper installation has occurred. In addition to providing an indication that an optical connection has been made, the conductive coating may be adapted to carry electrical signals. In this way, the fiber-optic cable would operate as an electrical transmission line and an optical transmission line.

Abstract: A partial emulation technique in which only the answers to poll frames and uplink information frames, or the slave part of the protocol, are emulated. All messages from the processor are passed down-link, and emulation is dependent upon the contents of an attendant list (452). In operation, the attendant list (452) is built by detecting responses to poll frames from the main controller (401). Once entries are made in the attendant list, partial emulation of responses to down link poll frames and up link information frames for each entry is allowed. No emulation of down link information frames occurs.
