Description
This message is sent to the board in order to control the configuration of the cross connect switch for more complex configurations.
Parameters
The MVD_MSG_SC_MULTI_CONNECT message includes the following parameters:
•local_stream
The logical reference of the local stream that the message relates to, that is, 0 to one less than the number LIUs corresponding to the liu_id.
•timeslot_mask
A
•mode
The mode of operation. The following table shows the permitted values and their meaning.
Value | Description | |
|
| |
| Make a simplex connection between an cross connect switch timeslot and a local | |
1 | LIU stream. Use the local_stream and timeslot_mask to specify the target | |
| destination on the CPU local bus. The source_st and source_ts. | |
|
| |
| Make a simplex connection between two CPU local bus stream timeslots. The | |
| source_st and source_ts parameters specify the source of the signal in terms of | |
11 | liu_id or CPU local bus stream reference and timeslots, respectively. The | |
local_stream relates to the outgoing liu_id stream and cannot reference a CPU local | ||
| ||
| bus stream. The timeslot_mask parameters specify the outgoing timeslots to which | |
| the source will be connected. | |
