# Creating a Clear Channel

To create an MSPP clear channel, use MSP_CHANNEL_ADDR and any channel-specific parameter structures to specify parameters.

For more information, refer to the Dialogic® NaturalAccess™ Media Stream Protocol Processing API Developer’s Manual.

Specify the channelType field in the MSP_CHANNEL_ADDR structure with one of the following values:

Value | Description
ClearFullDuplex | Full duplex transparent data flow between two endpoints.
ClearEncodeSimplex | Simplex transparent data flow from the Left endpoint (usually DS0) to Right endpoint (usually RTP).
ClearDecodeSimplex | Simplex transparent data flow from the Left endpoint (usually RTP) to Right endpoint (usually DS0).
