Digital Signal Processing (DSP) Management MIB module. The MIB module monitors the DSP resource and status. Acronyms & Terms ================ DTMF - Dual Tone Multi-Frequency. DTMF uses two frequencies, the high frequency omponent and the low frequency component, to generate digit signals. DSPFarm - DSPFarm ia a logical name given to a functionality which groups the DSP resources to provide certain service like transcoding and conferencing using DSP. DSPFarm profile - A DSPFarm profile logically groups the DSP to perform service like transcoding and conferencing. It is uniquely identified by a profile number. MTP - Media Termination Point. RTP packet received by MTP in the incoming call leg will be regenerated and send out through the outgoing call leg. transcode - Translating codec. transcoder is used to do codec translation. If incoming call leg negotiates codec-A and outgoing call leg negotiates codec-B then transcoder will convert received RTP packet from codec-A to codec-B or codec-B to codec-A. MTP hardware session - Media termination functionality with using DSP. MTP software session - Media termination functionality without using DSP. RTP - Real-time Transport protocol. Video Pool - A group of DSP resources dedicated to providing video services.
