Note that in this instance the two sub-rings will be dependent on their Ethernet
connections for configuration and data transmission but there will be no audio
path between them.
Figure 3-4: Ring Topology Dual Card Set Redundancy
Loss of Two Nodes
If two adjacent nodes are lost on the ring this will be handled as for the loss of
a single node where the nodes adjacent to the failed node will loop-back their
connections to the failed nodes healing the ring. The configuration software will
report the failure correctly as two failed nodes . If two non-adjacent nodes are lost
on the ring the nodes adjacent to the failures will loop-back their connections to
the failed nodes healing the ring into 2 separate smaller rings. The configuration
software will report the failure. Note that in this instance the two sub-rings will
be dependent on their Ethernet connections for configuration and data
transmission but there will be no audio path between them
Switching to the secondary ring will cause audio breaks or disturbances and
temporary loss of crosspoint data. The self healing mechanism is performed
autonomously by the fiber linking card whereas the switch-over between
redundant cards and rings requires software or operator intervention.
