Eclipse Omega Instruction Manual 3 - 1 3
In all fault cases involving recoverable cable faults or loss of nodes on
one or both rings the remaining nodes may experience audio breaks or
disturbances and temporary loss of crosspoint information or data.
Audio and data from a failed node will not be available to the remaining
nodes for the duration of the failure. When a ring with non-adjacent
failures sub-divides into two sub-rings, audio and data from the failed
nodes will not be available to the nodes in either sub-ring, audio and
data will continue to be available to nodes within the same sub-ring but
data may still be available to all nodes that are still functioning if there
is an intact, independent Ethernet connection to those nodes.
If a Matrix frame, connected as a node of the fiber-optic link is reset,
powered down or failed this will constitute a lost or failed node on both
rings and this node will experience audio breaks or disturbances and
loss of crosspoint information or data for up to 5 seconds after the fault
condition is cleared or repaired.

An example of how a system with multiple matrices would be wired up
is shown below in Figure 3-6.
