O/R Address Attributes and Forms In order for MHS users to address other MHS users, the X.400 standard specifies an address convention referred to as an Originator/Recipient address (O/R address). It is constructed by using a combination of the following fields: * Country * Administration management domain * Private management domain * Organization name * Organization unit names * Personal name * UA unique numeric identifier * X.121 address * Telematic terminal identifier * Domain defined attributes * Physical delivery attributes (1988 X.400 only) Forms of the 1988 X.400 Standard There are no defined forms of O/R addresses in the 1988 X.400 standard. Any combination of the O/R address attributes can be used. Forms and Variants of the 1984 X.400 Standard There are two defined forms of O/R address in the 1984 X.400 standard Within the first form, there are three variants. 1984 X.400 systems may not be able to handle undefined forms of O/R addresses. Form 1 Variant 1. Country (required) Administrative management domain (required) Domain defined attributes (optional; up to four occurrences) Plus one or more of the following: Private management domain Personal name Organization name Organization unit names (up to four occurrences) Form 1 Variant 2. Country (required) Administrative management domain (required) UA unique numeric identifier (required) Domain-defined attributes (optional) Form 1 Variant 3. Country (required) Administrative management domain (required) X.121 address (required) Domain-defined attributes (optional) The first variant consists of one or more attributes such as personal name, organization name, organizational unit names, and private domain names. The second variant consists of an identifier that distinguishes the user's UA from other UAs controlled by the same authority. Terminals with numeric keypads can use this form to enter O/R addresses. The third variant consists of an X.121 address. The escape digit defined for telex may be used to identify store-and-forward telexes. An originator may use only one of these representations per recipient. Form 2. X.121 address (required) Telematic terminal identifier (optional) Form 2 consists of an X.121 address. It specifies the originator or recipient of a message by identifying the telematic terminal.
