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.
If two adjacent fiber connections are lost on one ring and the other ring
has a similar failure 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 node healing the ring. The configuration
software will report the failure correctly as two failed cables . If two
non-adjacent fiber connections are lost on one ring and the other ring
has a similar fault the nodes adjacent to the failures will loop-back their
connections to the failed cables 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.
