  • Voice compression system having robust in-band tone signaling and related method
    Patent number: 5913189
    Abstract: A communication system, and related method, for reliably transmitting DTMF code signals through a low-bit rate channel employing a VSELP speech compression algorithm. The system adds relatively low-level noise to the analog DTMF signals before encoding by the compression algorithm. By adding the low-level noise to the DTMF signals, the tones associated with the DTMF signals can be reliably detected on the receiving end.
