# NCC.X.ADI_START

The following tables describes NCC.X.ADI_START parameters:

NCC.X.ADI_START
Dependent function: nccStartProtocol
Field | Type | Default | Units | Description
--- | --- | --- | --- | ---
mediamask | DWORD | 0x001F | mask | Controls which functions will be running or reserved when the call enters the connected (conversation) state. (The NOCC protocol enters this state immediately.) Reserved indicates that the DSP MIPS have been committed to the operation before the operation has actually started. The application must reserve DSP resources in advance by using this parameter for DTMF detection, silence detection, cleardown detection, and echo cancellation. A value can be formed by using the OR operator with any of the following bit masks or by using one of the specified constants: NCC_RESERVE_DTMF (0x0001): Reserve DTMF detection (not used for QX boards) NCC_RESERVE_SILENCE (0x0002): Reserve cleardown detector (not used for QX boards) NCC_RESERVE_CLEARDOWN (0x0004): Reserve DTMF detection (not used for QX boards) NCC_AUTO_DTMF (0x0008): Start DTMF detection NCC_AUTO_ECHO (0x0010): Start echo canceller NCC_ALL_MEDIA (0x001F): (NCC_RESV_CLEARDOWN| NCC_RESV_SILENCE| NCC_RESV_DTMF| NCC_RESV_AUTO_DTMF| NCC_RESV_AUTO_ECHO) NCC_ACCEPT_DTMF (0x100): DTMF detection in accept
