SDI Redundancy Topology (N+M , all nodes linked to the same matrix)
This topology consists of nominal nodes, redundant nodes and one
matrix.
 Matrix crosspoints between SDI sources and nominal nodes must be
static.
 Matrix crosspoints between SDI sources and redundant nodes must
be dynamic.
Figure 3-100. SDI topology: SDI redundancy - N + M, all nodes linked to the same matrix
SDI Redundancy Topology (1+1)
This topology consists of nodes with identical SDI sources.
 The nominal node is the node with the lower node Id.
 Additional unique SDI sources can be connected directly to nominal
node but in this case job using these sources will not be SDI
redundant job.
Figure 3-101. SDI topologies: SDI redundancy - 1+1
This topology is used to manage redundant SDI sources. The main
source is connected to the main node, the backup source is
connected to the backup node.
