AS/NZS 8825.1:1998

Specifies the definition of encoding rules that may be applied to values of types defined using the ASN.1 notation. It is implicit in the specification of these encoding rules that they are also to be used for decoding. This Standard is identical with and has been reproduced from ISO/IEC 8825-1:1995 and ISO/IEC 8825-1:1995/Cor.1:1996.

This Recommendation International Standard specifies a set of basic encoding rules that may be used to derive the specification of a transfer syntax for values of types defined using the notation specified in ITU-T Rec. X.680 (1994) ISO/IEC 8824-1:1995, ITU-T Rec. X.681 (1994) ISO/IEC 8824-2:1995, ITU-T Rec. X.682 (1994) ISO/IEC 8824 3:1995, and ITU-T Rec. X.683 (1994) ISO/IEC 8824-4:1995, collectively referred to as Abstract Syntax Notation One or ASN.1. These basic encoding rules are also to be applied for decoding such a transfer syntax in order to identify the data values being transferred. It also specifies a set of canonical and distinguished encoding rules that restrict the encoding of values to just one of the alternatives provided by the basic encoding rules.These encoding rules are used at the time of communication (by the presentation service provider when required by a presentation context).
