Eclipse Median Instruction Manual 3 - 1 3
In all fault cases involving recoverable cable faults or loss of nodes on
one or both 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.
