MVD_MSG_SC_MULTI_CONNECT – Multiple Connect Request
Synopsis
Message sent to the board to control the switch to connect multiple paths.
Format
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 32-bit mask representing up to 32 timeslots on the local stream. Bit 0 corresponds to timeslot 0. A 1 in
the mask indicates that the pattern should be output on this timeslot, a 0 indicates that it should be left
unchanged.
•
mode
The mode of operation. The following table shows the permitted values and their meaning.

Value
Description
1
Make a simplex connection between an cross connect switch timeslot and a local
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.
11
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
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.
