System Release 6.1 cPCI for Windows Release Guide — May 2006 40
Enhancement to dx_reciottdata( )
Two new modes have been added.
• Voice activity detector (VAD) with event notification (RM_VADNOTIFY).
• Initial silence compression (RM_ISCR)
Enhancements to SIT Templates
Improvements include the following:
• Broader default SIT sequence definitions to allow greater coverage for SIT
sequences detected in the field.
• New SIT sequence definitions in the SIT tone set for DM3 boards:
TID_SIT_NO_CIRCUIT_INTERLATA (or TID_SIT_NC_INTERLATA),
TID_SIT_REORDER_TONE_INTERLATA (or TID_SIT_RO_INTERLATA), and
TID_SIT_INEFFECTIVE_OTHER (or TID_SIT_IO).
• New catch-all SIT sequence definition to cover SIT sequences that fall outside the
range of the defined SIT sequences (TID_SIT_ANY).
• Support for the ATDX_CRTNID( ) function to allow retrieval of the SIT IDs.
Note: In this release, the new SIT sequences are not supported by the
dx_querytone( ), dx_deletetone( ), and dx_createtone( ) functions.
Support for TF_SETINIT flag in DV_TPT structure
This termination flag, used by DX_MAXSIL termination condition only, is now
supported on DM3 boards (on standard play/record functions). This flag was
previously supported on Springware boards only.
Support for speed control using 6 KHz coders
Users can adjust speed via DTMF or programmatically using dx_adjsv( ). The
following coders are now supported for speed control:
• 24 kbps OKI ADPCM (6 kHz 4-bit)
• 48 kbps G.711 A-law PCM (6 kHz 8-bit)
• 48 kbps G.711 mu-law PCM (6 kHz 8-bit)
Improved accuracy for call progress analysis
Qualification templates for positive answering machine detection (PAMD) and positive
voice detection (PVD) have been updated to accomplish higher successful PAMD and
PVD rates on DM3 boards. These new templates are incorporated in the firmware.
For more information, see the [sigDet] section of the DM3 Configuration Guide.
