# Enabling MSPP connections

MSPP channels are disabled when they are created. After the application establishes a connection by joining MSPP endpoints with an MSPP channel, the application can enable the connection with mspEnableChannel. mspEnableChannel opens the channel so that data flows between the connected endpoints. When invoking mspEnableChannel, specify the channel handle (chnhd) of the connected channel. As soon as the application transfers data to one of the connection's endpoints, the connection channel processes the data and passes it on to the endpoint at the opposite end of the connection.
