摘要： An automated telephone calling system receives a group of telephone numbers from a host computer. For each telephone number there is a corresponding record of unique information. The host computer is connected to drive a plurality of operator display terminals. Each number is automatically called and equipment provides detection of rings, busy signals, recordings and voice answers. When a party answers a call, the called line is connected to a non-busy one of a group of operations. At the same time a report is sent from a central controller to the host computer reporting which number has been successfully called and which operator has been selected for the audio connection. The host computer then calls up the record for the called number and transmits at least a portion of the record to the display for the selected operator. The operator is thus provided with an audio connection to the called party as well as a screen display of relevant information for that party. When all the operators are busy the called parties are placed on hold until an operator is free. The operators are thus provided with a continuous sequence of answered calls for optimum utilization of the operators' s time.

摘要： A method and apparatus are disclosed for recording digital data on magnetic tape with an audio recorder. A logic circuit receives the data to be recorded and outputs two sequences of high and low levels: one sequence directly corresponds to the data and the other inversely corresponds to the data. One sequence is first inverted with respect to the other and the two sequences are then combined and recorded. After a data sequence, the two logic circuit outputs are placed at the same level, and the subsequent inversion of one output level relative to the other causes the combined levels to reach an intermediate, third level.

摘要： A telecommunication system is arranged between a trusted automated interactive system and a non-secure agent. The trusted automated interactive portion is operable for bidirectional communications with a caller. The agent portion is arranged to be bridged onto a communication connection between the caller (or network chat user) and the trusted interactive system under certain conditions. Sensitive data transmitted between the system and a calling user may be blocked from being communicated to the agent even while the agent is bridged onto the connection. In one embodiment, information (such as a verification of authenticity of the caller) pertaining to the sensitive data (but not the sensitive data itself) is communicated to the agent.

摘要： A system and method for a packet Voice Response Unit (VRU) which directly utilize packet network protocols, such as those of the H.323 standard, to provide enhanced services via a packet network. The packet VRU generally operates within the packet network and is not required to provide data format translation or multiple device-type access. The packet VRU may be built entirely in software running on a network server with a standard packet network connection such as Ethernet or token-ring. In a preferred embodiment of the present invention, the packet VRU redirects the media stream from a source so that it is sent directly to a destination, instead of passing through the packet VRU. Alternatively, if the packet VRU must perform processing on the message contents, the packets may be sent to both the destination and to the packet VRU. The packet VRU may still retain call control over the media streams by maintaining the signaling and user input components of the call. In another preferred embodiment of the present invention, a gateway may convert user input indication signals received from a party connected via the gateway into user input indication messages in an out-of-band channel to be read by the packet VRU, separate from the redirected media streams. The packet VRU may generally provide the existing enhanced services of a synchronous VRU but in a packet network environment, and in addition provide enhanced services for multimedia communications.

摘要： An interval timer for timing multiple repetitive timing intervals. A single large clock register increments ticks of a high-speed clock. Successive previously-stored timing values are loaded into a single compare register which is preferably of equivalent length to the clock register. A comparator monitors the clock register's current value and compares it with the timing value currently loaded in the compare register. As the clock register's value reaches the current timing value in the compare register, an alert signal is generated and sent out to activate a particular timed operation identified by an event ID (“EID”) associated with the timing value in the compare register. The current timing value in the compare register is then discarded, and the next timing value in sequence is retrieved into the compare register. A repeat flag is carried with each timing value and associated EID. If the flag is set, the system recognizes the corresponding timing value as a repetitive interval timing value. Upon recognizing the repeat flag as set, the inventive mechanism refers to a separate repeat value lookup table indexed by EID. The mechanism retrieves the repeat value associated with the EID of the timing value just reached, adds this repeat value to the timing value just reached, and then inserts the resulting sum into the stack as a new timing value associated with the repeated EID.

摘要： A switchless Automatic Call Distribution (“ACD”) system distributing incoming calls to call agents networked via a low-cost data network such as an ethernet. Standard POTS calls are received from the Public Switched Telephone Network (“PSTN”), whereupon a POTS/packet gateway digitizes the signal (if necessary) and compresses it, advantageously from &mgr;-law format (64 Kbps) down to approximately 5-6 Kbps. The POTS/packet gateway then converts the signal into a packetized format. Responsive to a call distribution algorithm identifying the next available agent by IP address, the caller's packetized voice signals are distributed to the agent over the ethernet. At the same time, Web-enabled database tools generate “documents,” advantageously in html, containing database information regarding the caller. These documents are then distributed to the agent over the ethernet. The agent may then converse with the caller using a headset connected to a standard desktop computer running CODEC software to transmit and receive packetized voice signals. At the same time, the computer runs browser software to allow the agent to receive html documents and send back updated information while talking to the caller. As a result, the ACD system has been optimized into a switchless ethernet connecting agents operating standard desktop computers running low-cost CODEC and browser software.

摘要： A tool for scheduling the delivery of media objects within varying constraints of available bandwidth. In a preferred embodiment in which the invention is enabled by software executable on a general purpose multimedia grade computer, a system designer orchestrates the playback of a series of media objects on a playback "score" analogous to a musical score. The system designer can also see the results of his or her work by playing back the playback score in real time on a corresponding runtime view. The media objects are represented on the playback score as playback icons. Responsive to the designer's manipulation of playback icons on the playback score, the present invention further creates and displays a corresponding download score, also viewable by the system designer, in which download icons (corresponding to playback icons on the playback score) are automatically deployed and arranged to fill up a displayed "pipe" of available bandwidth. The topographical area of the download icons, as displayed, corresponds to the data size of the media objects. The download icons are displayed as rectangular or square-cornered polygonal shapes. As the playback score becomes more information-rich, the pipe tends to fill to capacity with download icons. Eventually, as more information is added, delivery tends towards an error condition where download can no longer keep up with demand (i.e. the pipe is full). When this happens, the invention highlights this condition to the designer. The designer must then take action to correct the error condition so that delivery of media objects is once again compatible with playback. Alternatively, in a second embodiment, the system automatically degrades the content of media objects according to preselected sequences and conditions. The corresponding reduction in data-richness of degraded media objects causes the delivery thereof to again be compatible with playback.

摘要： A system and method is disclosed for linking remote telecommunications ports connected to remote nodes wherein the functionality of a centralized switching system is distributed among the remote nodes. A multichannel bus couples the remote nodes to each other. In a preferred embodiment, the transmit channels of selected remote ports are permanently assigned to specified channels within the bus while the receive channels of the remote ports are permitted to float between all of the bus channels. In this distributed architecture, each node may receive a request from an associated port for a connection to another port. Each node is capable of performing the switching connections locally resulting in less message protocol being passed between nodes.
