This Recommendation International Standard makes use of the enhanced message store defined in ITU-T Rec. X.413 ISO/IEC 10021-5. It also includes body part definitions for voice, reports and notifications. The ASN.1 is aligned with new ITU-T Rec. X.680 ISO/IEC 8824-1 and ITU-T Rec. X.880 ISO/IEC 13712-1, while retaining complete compatibility with the 1988 and 1992 IPM protocols. Numerous defect corrections are incorporated. This revision includes definitions for an extended set of ASN.1 integer values for IPM security error diagnostic codes.
