The ANSI X9.8 PIN - Use stored decimalization tables only access control point may be enabled by itself.

When this access control point is enabled, CSNBPGN, CSNBCPA, CSNBEPG, and CSNBPVR services must supply a decimalization table that matches the active decimalization tables stored in the coprocessors. The decimalization table in the data_array parameter will be compared against the active decimalization tables in the coprocessor and if the supplied table matches a stored table, the request will be processed. If the supplied table doesn't match any of the stored tables or there are no stored tables, the request will fail.

PIN decimalization tables can be stored in the CEX3C coprocessors for use by callable services. Only tables that have been activated can be used. A TKE Workstation is required to manage the tables in the coprocessors.
