Unprotected connections

Unprotected configurations consists of end-to-end paths that do not have an
alternate path. In the case of the a fault on the unprotected path, traffic is lost.
Note: The OME6130 supports nodal provisioning. When provisioning an
end-to-end circuit, you must ensure that the traffic protection as well as
cross-connections are performed at the end-points as well as any
passthrough nodes that make up the end-to-end circuit.
