This topic lists the DSP files needed for particular ADI service functions. Specify the files to be loaded in the board keyword file. Use the OAM API to load DSP files onto boards. For more information, refer to the board installation and developer's manual.
DSP files ending in .dsp have mu-law and A-law versions. The names shown here are for the mu-law version. The A-law files have _a appended to the file name. For example, the A-law version of voice.dsp is voice_a.dsp. Some DSP files have versions with _j appended to the file name. For example, the V.23 version of adsir.dsp is adsir_j.dsp.
Note: DSP files CG 6565/C and CG 6060/C boards use an .f41 file extension.

Description |
|---|---|---|
|
adsir(_j).m54 |
adsir(_j).fxx |
Contains the caller ID function that decodes the modem burst occurring between the first and second rings on a loop start line. This file also contains the FSK data receiver. Use adsir.xxx if one of the loop start protocols is used and the parameter adilps.cidsupport is set to 1. Use this file for adiStartReceivingFSK. (_j) is the V.23 variant. |
|
adsix(_j).m54 |
adsix(_j).fxx |
Contains the FSK data transmitter. Use this file for adiStartSendingFSK. (_j) is the V.23 variant. |
|
callp.m54 |
callp.fxx |
Contains voice and tone detectors used for call progress detection and for general tone detection. Use callp.xxx if any outgoing or two-way trunk protocol is in use and for adiStartCallProgress. |
|
dtmf.m54 |
dtmf.fxx |
Contains the DTMF receiver and the energy/silence detector. Use dtmf.xxx for DTMF detection. The energy/silence detector is used by the record functions and by adiStartEnergyDetector. |
|
dtmfe.m54 |
dtmfe.fxx |
Is a variation of dtmf.xxx, optimized for use with the echo canceller (echo.xxx). dtmfe.xxx yields better talk-off resistance but requires the echo canceller to achieve the best cut through performance. |
|
echo.m54 |
echo.fxx |
Contains the echo cancellation function. The echo canceller removes reflected energy from the incoming signal, which improves DTMF detection and voice recognition while playing. Use echo.xxx if echo cancellation is enabled. See adiStartProtocol and the ADISTART_PARMS category. Note: Substitute dtmfe.xxx for dtmf.xxx when using the echo canceller. |
|
echo_v3.m54 |
echo_v3.fxx |
Provides higher performance and support for longer echo tails. Requires more resources than echo.x54 and can decrease the number of ports. |
|
echo_v4.m54 |
echo_v4.fxx |
Contains the echo cancellation functions available in echo_v3.x54, as well as comfort noise generation and tone disabling features. |
|
None |
g723.fxx |
CG boards only. Contains ITU G.723.1 play and record functions for both 5.3 kbit/s and 6.3 kbit/s rates. The codec data is output as raw bytes of the encoded 30 ms frames. |
|
g726.m54 |
g726.fxx |
Contains ITU G.726 ADPCM play and record functions. G.726 is a standard for 32 kbit/s speech coding. Note: These functions require more DSP processing time than the functions in voice.xxx. You cannot run as many actively playing or recording contexts as you can with other speech encodings. |
|
None |
g729.fxx |
CG boards only. Contains ITU G.729A play and record functions. The 8 kbit/s codec data is output as raw bytes of the encoded 10 ms frames. |
|
gsm_ms.m54 |
gsm_ms.fxx |
Contains play and record functions for MS-GSM speech encoding at 13 kbit/s. |
|
gsm_mspl.m54 |
gsm_mspl.fxx |
Similar in operation to gsm_ms.m54, except that maximum output of the play function is limited. |
|
ima.m54 |
ima.fxx |
Contains play and record functions for IMA ADPCM speech encoding, at 24 kbit/s or 32 kbit/s. |
|
mf.m54 |
mf.fxx |
Contains the multi-frequency receiver function. Required for any trunk protocol that uses MF signaling and also by adiStartMFDetector. |
|
oki.m54 |
oki.fxx |
Contains play and record functions for OKI ADPCM speech encoding, at 24 kbit/s or 32 kbit/s. |
|
ptf.m54 |
ptf.fxx |
Contains precise tone filters. On AG boards, loop start protocols use ptf.xxx for the cleardown detector. On AG and CG boards, use ptf.xxx for adiStartToneDetector and adiStartCallProgress. |
|
rvoice.m54 |
rvoice.fxx |
Contains PCM play and record functions. rvoice.xxx is required to play or record with an encoding of ADI_ENCODE_MULAW, ADI_ENCODE_ALAW, or ADI_ENCODE_PCM8M16. |
|
rvoice_vad.m54 |
rvoice_vad.fxx |
Contains PCM play and record functions. Record functions can enable voice activity detection. rvoice_vad.xxx is required to play or record with an encoding of ADI_ENCODE_MULAW, ADI_ENCODE_ALAW, or ADI_ENCODE_PCM8M16. |
|
signal.m54 |
qtsignal.f54, 8tsignal.f54, (not required for CG 6565/C and CG 6060/C boards) |
Contains signaling, ring detector, and pulse functions. These are out-of-band functions that typically operate on the MVIP signaling stream. Required for any trunk protocol except NOCC. Also required for adiStartSignalDetector, adiQuerySignalState, and adiStartPulse. |
|
tone.m54 |
tone.fxx |
Contains the tone generation function. Required for all trunk protocols except NOCC. Also required for adiStartTones, adiStartDTMF and adiStartDial, and for any record function to generate the beep. |
|
voice.m54 |
voice.fxx |
Contains NMS Communications ADPCM play and record functions. The compressed speech is in a framed format with 20 milliseconds of data per frame. Speech is compressed to 16, 24, or 32 kbit/s, or it is stored as uncompressed mu-law or A-law (64 kbit/s). This file is required to play or record with encoding values of ADI_ENCODE_NMS_16, ADI_ENCODE_NMS_24, ADI_ENCODE_NMS_32, or ADI_ENCODE_NMS_64. |
|
None |
None |
Substitute these files for voice.dsp to apply speed up to NMS Communications ADPCM encoded speech. |
|
wave.m54 |
wave.fxx |
Contains play and record functions for PCM speech in formats commonly used in WAVE files, including 8 and 16 bit, 11 kilo-samples per second sampling. |
