Abstract: A method and system for wireless data communication, including the steps of receiving an input request, filtering data from at least one database to produce filtered data in response to the input request, attaching formatting instructions to the filtered data corresponding to a data format specific to a wireless data terminal to produce a pre-formatted response, sending the pre-formatted response to a wireless transmitter, formatting the pre-formatted response according to the formatting instructions to produce a formatted response, and transmitting the formatted response from the wireless transmitter to the wireless data terminal.

Abstract: Signaling tone detection systems are presented that may allow for reductions in talk-off, cut-through, or both. In one general aspect, a detection system includes an outgoing signaling tone detector responsive to an output from a first station to a communication channel. An incoming signaling tone detector is responsive to an input to the first station from the communication channel. A sensitivity control input of the incoming signaling tone detector is responsive to a detection output of the outgoing signaling tone detector. This and other configurations may allow a system to detect tones more reliably, or they may allow a system with particular computational capabilities to detect more tones with a similar level of accuracy.

Abstract: A network communication system includes a packet translator operatively connected between a tributary network port and a trunk network port. A tributary format is communicated through the tributary network ports and includes tributary packets that each include a header field and a data field. An aggregate format is communicated through the trunk network port, and includes a packet that includes an aggregate header field and the data fields.

Abstract: A method of facilitating telephony communications over a packet-switched network includes detecting signaling tones in an audio stream and blocking them from the stream in response to the detecting. After the blocking, the audio stream is sent over an undependable channel in the packet-switched network. The detected signaling tones can be sent over a dependable channel instead of the undependable audio channel.

Abstract: Aspects of the present invention are directed to communications circuits and method that utilize associative memories for providing telephony switching of data between different time slots in one or more time division multiplexed (TDM) serial data lines or streams. The communications circuit may include a first content-addressable memory block and a second content-addressable memory block each of which receive the same address for independently generating tags for accessing a data memory to provide data to or receive data from TDM data lines.

Abstract: A signal processing system includes a control processor that has a bi-directional port, signal processors that each have a serial port, a bridge that has serial ports each operatively connected to a serial port of one of the signal processors, and a bi-directional port operatively connected to the bi-directional port of the control processor.

Abstract: The present invention involves a system and method for classifying information received by a communications device. A first parameter having a first parameter range and a second parameter range, and a second parameter having a third parameter range and a fourth parameter range, are defined. A first class having one of the first parameter and the second parameter ranges, and one of the third and the fourth parameter ranges, are also defined. A second class having another one of the first parameter and the second parameter ranges, and another one of the third and the fourth parameter ranges, is also defined. Information having a first parameter value and a second parameter value is received. The method determines if the first parameter value is within one of the first and second parameter ranges and if the second parameter value is within one of the third and fourth parameter ranges is made.

Abstract: The present invention relates to a system and method for searching information. The method involves defining a first node having a first range, and a second node having a second range that is either less than or greater than the first range. Each of the first and second ranges has a plurality of range values, and each of the range values has data associated therewith. Information having a value is then received. The method determines if the value is located in the first node, if so, data associated with the value is retrieved. Otherwise, the method determines if the value is located in the second node. Data associated with the value is retrieved if the value is located in the second node.
