Abstract: An improved data communication technique may be employed with modems through a packet network. The disclosed technique facilitates a virtual end-to-end connection between two modems such that the two modems can effectively behave as if directly connected to each other, unaware of any modifications to the data being transferred or to the protocols configured within the communication connection. Preferably, a data communication system for carrying out the communication technique demodulates data coming from a first modem, transports the demodulated data in packets between two gateways, and then remodulates the data before delivering to a second modem at the other end.

Abstract: In accordance with one aspect of the present invention, the detection of voice signals versus modem signals in a data communication system may be conducted, a determination can be made whether existing VoIP algorithm functions or characteristics may be appropriate for modem communications, and then the VoIP algorithms may be modified to improve operating conditions for a modem connection. Additionally, the existing VoIP algorithm functions and network characteristics within the data communication system that may degrade modem performance can be identified prior to the determination of whether the VoIP algorithm functions are appropriate for modem communications. In accordance with another aspect, the detection between voice signals and modem signals can also comprise the determination as to a particular type of modems signal. Further, control of the adaptive jitter buffer to remove or reduce adaptation during detection of modem signals can be provided.

Abstract: A digitized signal detection system where the bit rate encoding is changed dynamically to provide encoding for different type signals and formats at bit rates optimized to properly reconstruct the input signal whether speech or non-speech and therefore can transfer signals of different character on a frame by frame basis. A change of encoding format can make the system a speech or music recognizer dependent what is to be listened for. Three basic components a recognizer which categorizes the type of input signal, an evaluator which evaluates the category of quality of the reconstructed signal and a recommender which make as recommendation based on the quality to change standards to encode the signals received pursuant to a standard which provides for improved quality. The dynamic signal detector receives the input signal directly and extracts the parameters for evaluation. These parameters are tested and a determination made if a switch of standards are required. To improve the reconstructed signal.
