Figure 3-3: Ring Topology Single Card Set Redundancy
Loss of Single Fiber Connection
If a single fiber connection is lost on one ring and the other ring is intact then the
active ring always attempts to heal itself by reversing the direction of data flow to
bypass the failed connection. If the extent of the failure is such that the active
ring is unable to heal itself then the system will switch to the secondary ring.
The self healing mechanism is performed automatically by the Fiber Linking
Card whereas the switch-over between redundant cards and rings requires
software or operator intervention. Switching to the secondary ring will cause
audio breaks or disturbances and temporary loss of crosspoint data.
If a single fiber connection is lost on both rings the nodes adjacent to the failures
will loop-back their connections to the failed cables healing the rings and the
most intact ring will be used.
The Eclipse Configuration Software (ECS) will report any failures in the fiber
connection system.
