Circuit Discovered, State OSS
The OCHNC circuit is shown under the Circuits tab, but the Status field reports PARTIAL. This
applies to a circuit successfully built-up when the network falls into scenarios a. or b (OSC link fail
or APC disabled), described below.
1.12.3.1 Prerequisites for Successful OCHNC Circuit
One (or more) of the Span OSC links involving the OCHNC circuit has not been properly
established. The WPP application prevents the creation of any circuit passing through the failing
span. Prerequisite condition
has not been met.
a. The APC application is internally disabled due to the presence of a Critical alarm somewhere
in the network. As a consequence, no reliable information about the number of active channels
can be shared among the nodes and the creation of any further OCHNC circuit is prevented until
the faulty condition is fixed. Prerequisite condition
OCHNC Circuit Creation
One (or more) of the intranode connections between two DWDM cards associated with the
b.
circuit have not been properly created. Prerequisite condition
