This entry is used to model a unidirectional or
bidirectional patch between two interfaces on the same
network element.
An entry is created when the network element is provisioned to
indicate that two interfaces on the network element have been
patched together using an optical patch cord.
Prior to creating an entry in the table, the manager should
obtain a unique value of cOPatchIndex by reading the
cOPatchIndexNext object. When an entry in the table is
created, the cOPatchIntfPatchId values in the corresponding
cOPatchIntfTable rows are filled in by the agent.
