Description:

This message is sent to the DSI SPCI Board to establish a connection from the CT bus to an outgoing timeslot on the T1/E1 Line Interface Unit (LIU). It is issued by the application and is typically used at the start of each call although it may also be issued during a call to connect to a different resource.

Correct operation of this message is dependent upon the use, at initialization time, of the MVD_MSG_SC_DRIVE_LIU message (or the LIU_SC_DRIVE command in config.txt when using s7_mgt).

When a new call arrives the application uses this message to connect the appropriate resource from the CT bus out to the network. When the call finishes, the application uses the MVD_MSG_SC_FIXDATA message to generate the appropriate IDLE pattern on the LIU.

The MVD_MSG_SC_LISTEN message can also be generated at configuration time using s7_mgt as a result of the SCBUS_LISTEN command in the config.txt file. However, this only sets up a static configuration and still requires the user application to control any dynamic connections.
