Description
This message is sent to the DSI SPCI Board to configure the operating mode a line
interface unit. All configuration parameters must be supplied in the message (it is not
possible to modify individual operating parameters in isolation). On receipt of the
message the board first verifies that the fitted hardware options support the requested
operating mode and then initializes (or re-initializes) the line interface unit.
The confirmation message (if requested) indicates success by status of zero.
Parameters
