LIU CT bus Initialization Request
Synopsis:
This message is sent to the board at initialization time to set up a static
switch path through the board between the Line Interface Unit (LIU) and the
CT bus. It connects selected incoming voice timeslots from a T1/E1 LIU to a
sequential block of channels on the CT bus and prepares the outgoing
timeslots for subsequent use by the MVD_MSG_SC_LISTEN message.
Note:
When using s7_mgt, this message is generated by s7_mgt as a result of the
LIU_SC_DRIVE command. It therefore does not need be generated by the user.
