  • Digital voice recording and reproduction and telephone network signalling using direct storage in RAM of PCM encoded data
    Patent number: 4829514
    Abstract: A digital voice recording and reproducing device, preferably connected to a telephone network uses a storage RAM to store voice messages and digital signals. An internal processor connected to the storage RAM processes digital signals to and from the storage RAM. A high speed RAM connected to the internal processor receives and transmits digital signals to and from the internal processor. Encoders and decoders encode voice signals into pulse code modulated (PCM) signals to be delivered into the high speed RAM, and decode digital PCM signals from the high speed RAM. A high speed processor (HSP) connected to the high speed RAM delivers signals from a switch to the high speed RAM.
