  • Test unit for use at a network interface device
    Patent number: 6912269
    Abstract: A test unit provides testing capability at a network interface device (NID). The test unit may be remotely activated so that testing is initiated upon activation from a remote site. In one embodiment, a characteristic signal is sent over a telephone line toward the NID. A characteristic signal is detected and the testing unit is activated. The testing unit may perform multiple types of tests, including tests for detecting line loss, line noise and latency. The test may be implemented using electronic circuitry or using an intelligent computer system.
    Type: Grant

  • Low-rate encoding/digital speech interpolation system
    Patent number: 5226044
    Abstract: A low-rate encoding/digital speech interpolation (LRE/DSI) system architecture is organized to eliminate the LRE mistracking problem normally associated with DSI-induced speech clipping, to reduce the number of LRE codes required and to provide a mechanism for gradually introducing overload.
