2.1. Voice Driver
The Voice Driver communicates with and controls the voice hardware. Voice hardware consists of voice store-and-forward boards which include the following boards:
For SCbus-based applications:
The D/41ESC, D/160SC-LS, D/240SC, D/320SC, D/240SC-T1, and D300SC-E1 boards support a range of Voice Processing features such as:
The DTI/241SC, DTI/301SC, LSI/81SC, and LSI/161SC boards support the following Voice Processing features:
User-defined tones are CST events, but detection for these events is enabled using dx_addtone( ) or dx_enbtone( ). See the Voice Software Reference: Voice Features Guide for information on Global Tone Detection functions.
Boards are treated as board devices and channels are treated as channel devices or board subdevices by the Voice Driver.
The SCbus is a real-time, high speed, time division multiplexed (TDM) communications bus connecting Signal Computing System Architecture (SCSA) voice, telephone network interface and other technology resource boards together. SCbus boards are treated as board devices with on-board voice and/or telephone network interface devices that are identified by a board and channel (time slot for digital network channels) designation, such as a voice channel, analog channel or digital channel.
For more information on the SCbus and SCbus routing, refer to the SCbus Routing Guide and the SCbus Routing Software Reference.
