1.3.6.1.2.1.34.8.1.6.1
Definition of a single mapping from an SSCP-supplied SLU name to a local SLU name. Note: In certain pathological cases, it is possible that an SSCP will send on an ACTLU for a local LU an SLU name currently represented by an entry in this table that associates it with a different local LU. In these cases the association from the newer ACTLU SHOULD be the one represented in this table.
