This read-only Integer32 (1 to 255) serves as the index for hwDccRuleTable/hwDccRuleEntry, the dialer rule table; the source description for both the object and its table is only the placeholder "Description.", so the value should be read as the numeric identifier of a configured dial rule rather than any richer status. An admin uses it to enumerate and cross-reference which dial rule's protocol type (hwDialProType) and ACL (hwDialAclNumber) apply to a given rule row. As an illustrative example, hwDialRule might return 5 to identify dial rule 5, under which the admin then reads the associated protocol and ACL columns.
