- Annex A Test Notation
-
- A.1 Introduction
-
- This annex is an integral part of this Recommendation and describes
- the notation used in the test suite manuals.
-
- The test notation described here is based on the test notation
- called Tree and Tabular Combined Notation (TTCN) that has been
- developed jointly by ISO and CCITT.
-
- The notation described in this Recommendation is derived from an
- early form of TTCN and has been developed specifically for use in
- the MHS conformance testing specifications.
-
- Each of the MHS test suites is specified in five parts:
-
- - Declaration Part
- - Dynamic Part
- - Constraints Part
- - Test Case Identification
- - Cross-References
-
- A.2 Declaration Part
-
- The Declaration Part declares the environment and objects used in
- the test suites and is composed of 7 sections:
-
- - Test Configurations
- - Test Suite Parameters (TSPs)
- - Service Access Points (SAPs)
- - Abstract Service Primitives (ASPs)
- - Protocol Data Units (PDUs)
- - Timers
- - Abbreviations
-
- A.2.1 Test Configurations
-
- The points of control and observation are declared in this section.
-
- A.2.2 Test Suite Parameters
-
- Every MHS Test Suite has a set of parameters whose values are fixed
- prior to testing and which are used to define a specific testing
- environment.
-
- TSPs are declared in tabular form as shown in Figure A-1/X.403.
-
-
-
-
-
-
-
-
-
-
-
- Figure A-1/X.403 Test Suite Parameters.
-
-
-
-
-
-
-
-
-
-
-
-
- By convention the name of each Test Suite Parameter in the MHS test
- suites is of the form:
-
- TSP_<name>
-
-
- A.2.3 Service Access Points (SAPs)
-
- Service Access Points are used as points of control and observation
- in the MHS Test Suites and are declared in tabular form as shown in
- Figure A-2/X.403.
-
-
-
-
-
-
-
-
-
-
- Figure A-2/X.403 Service Access Points.
-
-
- By convention the name of a SAP in the MHS Test Suites is generally
- one capital letter, such as T, U, V (for tester SAPs) or I, J, K
- (for IUT SAPs).
-
- A.2.4 Abstract Service Primitives
-
- Each ASP type and its associated parameters used in a test suite is
- declared in tabular form as shown in Figure A-3/X.403.
-
-
-
-
-
-
-
-
-
-
- Figure A-3/X.403 Abstract Service Primitives.
-
-
- The name of the ASP is specified in the "ASP" field and is derived
- from the corresponding name in the X.400 Series of Recommendations.
- The SAP at which the ASP occurs is specified in the "SAP" field.
- The parameters of the ASP are declared in the "NAME" column
- together with information in "RANGE OF VALUES OR TYPE", "COMMENTS"
- and "Conditional/Mandatory" columns.
-
- Since there are no IPMS(P2) ASPs defined in the Recommendations, in
- order to describe conformance tests it has been necessary to
- construct hypothetical ASPs at the upper boundary of the User Agent
- Layer. This does not imply, however that manufacturers are required
- to implement these ASPs within their systems. It serves only to
- formalize the requirements for observation and invocation of IPMS
-
-
-
-
-
-
- service elements by the use of these new ASPs. The relation between
- IPMS service elements and the actual behaviour of the IUT has to be
- specified in the implementation-dependent PIXIT.
-
- A.2.5 Protocol Data Units
-
- The PDU types used in test suites are declared in the form of
- tables as shown in Figure A-4/X.403. These PDUs are not defined
- explicitly in the test suite, but are given a precise reference to
- the full definition in the X.400 Recommendations, in the type name
- section of the table.

-
- A.2.6 Timers
-
- This section declares the timers to be used. Timer values are
- expressions in terms of Test Suite Parameters, and are fixed for
- the whole test suite. Timer values are declared in tabular form as
- shown in figure A-5/X.403.

-
- Abbreviations used in the Test Suite are defined in the form of a
- table as shown in Figure A-6/X.403.

- A.3 Dynamic Part
-
- The Dynamic Part defines the test cases of a test suite in terms of
- trees of behaviour.
-
- Sections A.3.1 and A.3.2 describe generally how trees of behaviour
- are defined.
-
- Section A.3.3 describes the content and use of Defaults Library.
-
- Section A.3.4 describes the content and use of Test Step Library.
-
- Section A.3.5 describes how each test case in the main body of a
- test suite is specified.
-
- A.3.1 Proforma table for Test Behaviours

- Figure A-7/X.403 Behaviour Description.
-
-
- <title> BEHAVIOUR:
-
- Title of the behaviour: DEFAULT for the Default Library;
- DYNAMIC for the Test Step Library and test cases.
-
- IDENTIFIER:
-
- This provides a unique identifier for the behaviour
- description.
-
- DEFAULTS:
-
- This lists the identifiers of default behaviour descriptions
- which are to be used in conjunction with the Dynamic behaviour
- shown in the "BEHAVIOUR DESCRIPTION" part.
-
- BEHAVIOUR DESCRIPTION:
-
- Test behaviour is defined using a tree notation as described
- in A.3.2.
-
-
-
-
-
-
-
- LABEL:
-
- The LABELS column may be used to identify events. Branches
- between events (i.e. "GO TO") are specified by " > Label" in
- the behaviour tree.
-
- CONSTRAINTS REFERENCE:
-
- For each ASP event of a behaviour tree line, this column gives
- the reference to the specific ASP value defined in the
- Constraints Part.
-
- COMMENTS:
-
- This column provides comments which ease understanding of the
- events. Additional comments may be given in the "Extended
- Comments" area. This column can also be used to identify test
- PDUs associated with test events.
-
- RESULT:
-
- This column indicates which test events generate test verdicts.
- Values of test verdicts are:
-
- - pass: no misbehaviour of the IUT is detected.
- - fail: misbehaviour of the IUT is detected.
- - inconclusive: the observed behaviour does not allow the
- assignment of a pass or fail verdict.
-
- A.3.2 Tree notation for test behaviours.
-
- Trees of behaviour are defined in terms of events which are
- generally of the form
-
- <SAP>!<event>
-
- or of the form
-
- <SAP>?<event>
-
- The <SAP> is the point of control and observation at which the
- <event> occurs. The SAPs used are those declared in the Declaration
- Part.
-
- The "!" symbol indicates that the event is sent from the SAP and
- "?" indicates that the event is received at the SAP.
-
- The <event> can be
-
- - an ASP event
- - a timer event
- - a OTHERWISE pseudo-event.
-
- A.3.2.1 Single ASP events.
-
- If the <event> is an ASP event then the names for the ASPs are
- those specified in the Declaration Part (the value is specified as
- a reference in the CONSTRAINTS REFERENCE column).
-
-
-
-
-
-
-
-
-
-
-
-
- Example line for an ASP event:
-
- I?DELind
-
- This means that a Deliver Indication is received at
- the IUT's SAP I.
-
- A.3.2.2 Single Timer events.
-
- If <event> is a timer event then it is of the form
-
- <operation> <parameters>
-
- The "start" operation can take one of two forms:
-
- Start <timer type>
- Start (<timer type>,<timer id>)
-
- Where <timer type> is defined in the Declaration Part and has a
- fixed value associated with it defined in terms of TSPs. The <timer
- id> allows a name to be attached to an instance of a timer type.
-
- The other operations are:
-
- Cancel: cancels a running or suspended timer
- Suspend: suspends a running timer
- Resume: resumes a suspended timer
- Timeout: expiration of a running timer
-
- These operations take one of two forms:
-
- <operation> <timer type>
- <operation> <timer id>
-
- where <operation> denotes the operation. When the timer was started
- using the form "Start <timer type>", the form "<operation> <timer
- type>" must be used; when the timer was started using the form
- "Start <timer id>", the form "<operation> <timer id>" must be used.
-
- Example:
-
- I!Start T/I-timer_1
-
- means that at the IUT's SAP I the T/I-timer_1 (e.g. for a
- transmission time for a UAPDU to be transferred from the tester
- to the IUT's user) is started.
-
- I?Timeout T/I-timer_1
-
- means that at the IUT's SAP I the timeout of the above timer is
- received.
-
- A.3.2.3 Single OTHERWISE events.
-
- If <event> is the OTHERWISE pseudo-event, this indicates an
- unspecified event.
-
- Example:
-
-
-
-
-
-
-
- T?OTHERWISE
-
- Means that at the tester's SAP T an unspecified event
- is received.
-
- A.3.2.4 Trees of behaviour
-
- Trees of behaviour combine events in two ways:
-
- - as sequences of events
- - as alternative events
-
- The two combination kinds are distinguished by indented and
- vertical alignment respectively.
-
- Example of a sequence of events:
-
- I!SUBreq
- I?SUBcon
- T?TRNind
-
- This means that first at the SAP I a Submission Request is
- sent, then at the same SAP a Submission Confirmation is
- received, after which a Transfer Indication is received at the
- tester's SAP T.
-
- Example of alternative events:
-
- T?DELind
- T?Timeout I/T-timer
-
- This means that at SAP T either a Deliver Indication is
- received or alternatively the timeout is received there.
-
- To build up a complex behaviour tree, the two kinds of combination
- can be mixed.
-
- Example:
-
-
-
-
-
-
- This means that after sending a Submission Request at I, either
- a Submission Confirmation is received at I, followed by the
- receipt of a Transfer Indication at T, or a Disconnect
- Indication is received at T.
-
- A.3.3 Defaults Library
-
- General default behaviours which are used by several test cases are
- defined in the Defaults Library using the format shown in figure
- A-8/X.403. The name of the default is of the form:
-
- LIB_<name>
- or
- LIB_<name> [X]
-
-
-
-
-
-
-
-
-
-
-
-
- where X is a place holder which is replaced by an actual SAP when
- applying the default element in a particular Test Case.
-
- Note:
-
- Where particular default behaviour applies to a single test case
- only the behaviour table is associated with that test case and the
- identifier is not prefixed with "LIB_".

-
-
- A.3.4 Test Step Library
-
- Where a sequence of test steps is of use in several test cases they
- can be included in the Test Step Library and given a name of the
- form:
-
- LIB_<name>
-
- Note:
-
- Where a test step applies to a single test case the behaviour table
- is associated with that test case and the identifier is not
- prefixed with "LIB_".

-
-
-
-
-
-
-
- A.3.5 Test Case
-
- Each test case in the main body of the test suite is described in
- terms of three headings (a) - (c), and a behaviour tree (d)
-
- (a) Test Reference and Test Identifier
-
- These elements give a unique reference and identifier for each
- test case and are described fully in section A.5.
-
- (b) Summary
-
- A brief overview of the purpose of the test is provided.
-
- (c) Test Description (optional)
-
- This provides an informal description of the actions and events
- that should take place during the test and an informal verdict
- criteria.
-
- (d) Behaviour Tree
-
- Dynamic behaviour is described using the tree notation defined
- in section A.3.2.

-
-
- Note 1: In this field all Default Library Identifiers used are
- inserted. Where necessary, the SAP at which they are applied
- is also identified. If for example the field contains the
- entry:
-
- LIB_unexpected [T]
-
- it means that the subtree associated with this Default
- Behaviour is considered to be associated with the SAP T.
-
- Note 2: Test Step Library behaviour is included in the behaviour
- tree using the following notation:
-
- + <Test Step Library Identifier>
-
- Note 3: The behaviour tree of every Test Case provides the
- verdicts pass, fail, and where appropriate inconclusive.
-
-
-
-
-
-
-
-
-
-
-
-
- Note 4: When using Default Library elements it is possible
- that some of the verdict alternatives are "hidden" in the
- Default Library element.
-
- A.4 Constraints Part
-
- The Constraints Part of a Test Suite specifies the values and their
- encoding of all instances of ASPs, Test PDUs, Base PDUs and Library
- Components. The Constraints Parts is divided into the following
- sections:
-
- - Introduction to Constraints Part
- - ASP Constraints
- - Test PDU Constraints
- - Base PDU Constraints
- - Components Library
-
-
-

-
- Figure A-11/X.403 The structure of the Constraints Part.
-
- A.4.1 ASP Constraints
-
- Values of ASPs are defined as specific instances of a generic ASP.
-
- A.4.1.1 Specification of a "Generic" ASP
-
- A generic ASP is defined using the format shown in Figure A-12/X.403.
-
-
-
-
-

-
-
-
- Figure A-12/X.403 Generic ASP specification.
-
- The "FIELDS" column is used to list all the parameters of the ASP.
-
- The "VALUE or REFERENCE" column is used to specify a value for each
- parameter and this can be done in four ways:
-
- (a) As a reference which can be a TSP name or a library component
- name.
-
- (b) As an explicit value.
-
- (c) As "-" to indicate that this parameter may be omitted in
- specific instances of this ASP.
-
- (d) As "?" to indicate that for "request" ASP's this parameter must
- have a value defined in a specific instance if it is a component
- of interest.
-
- A.4.1.2 Specification of ASP Instances
-
- Specific values of ASPs are defined using the tabular format shown
- in Figure A-13/X.403.
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- Figure A-13/X.403 Specific ASP value.
-
-
- The "INSTANCE NAME" column is used to identify specific instances
- of the ASP used in the test suite.
-
- The "MODIFIED PARAMETER" column identifies, for "request" ASP's
- those parameters whose values are to be modified from the generic
- ASP specification, and for "notification" ASP's those parameters
- whose values are to be checked.
-
- The "VALUE or REFERENCE" column can contain either specific values
-
-
-
-
-
-
-
-
-
-
-
- or references to library components ASPs or test PDUs.
-
- A.4.2 Specifying PDU values
-
- The MHS test suite contains a large number of test PDU values. Each
- PDU is defined in terms of modifications to one of the small number
- of "base" PDUs.
-
- For convenience commonly used PDU components are defined in a
- library and are referenced by test PDUs and base PDUs.
-
- A.4.3 Base PDUs
-
- A.4.3.1 Base PDU specification
-
- Base PDUs are not themselves used as test PDUs but they serve as a
- basis from which to derive the test PDUs. Usually only a few Base
- PDUs need to be specified.
-
- The name of a Base PDU is of the form:
-
- BASE_<PDUtypename>_<number>
-
- An example of a Base PDU is shown below.
-
- Example:
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- The value or value reference of each element of the structure is
- specified within square brackets ("[" and "]") under the VALUE or
- REFERENCE heading.
-
- When specifying the encoding of a PDU for encoding/decoding
- tests,two additional columns are used to specify the ID Code [ID]
- and Length Indicator [LI] of each element of the PDU. The format
- for doing this is shown in the example below.
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- The values of ID and LI can be specified explicitly to allow
- invalid and various forms of valid codings to be defined. The
- mnemonic "LI" is used to indicate that any valid encoding of length
- is allowed.
-
- A.4.3.2 Identifying the components to be modified
-
- A component which is to be replaced in a PDU is identified by a
- path through the declaration of the PDU. The path is written as a
- list of elements, each separated from the next by a ".". The
- elements in the list can be labels which appear in a BASE PDU,
- components which appear in the left-hand side of a labeled
- declaration, or components which appear in the left-hand side of
- the expansion of a library reference in the right-hand side of a
- declaration.
-
- For example, consider the following definitions:
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- In order to reference "a", the path would be instance_1.a.
- In order to reference "e", the path would be instance_1.b.d.e.
-
- A.4.4 Test PDUs
-
- Test PDUs are defined in terms of operations on Base PDU's. These
- operations refer to Library Components, TSPs or specific values.
-
- There are two kinds of test PDU:
-
- - PDUs sent by the tester (IUT as recipient)
-
-
-
-
-
-
-
-
-
-
-
-
- By convention the names of these PDUs are of the form
-
- <PDU name>_x_<number>
-
- where x is the number of the base PDU from which the test PDU is
- derived.
-
- - PDUs received by the tester (IUT as originator)
-
- By convention the names of these PDUs are of the form
-
- <PDU name>_0_<number>
-
- where "0" indicates that these test PDUs are not derived from a
- base PDU.
-
- A.4.4.1 Test PDUs sent by the tester
-
- A test PDU sent by the tester to the IUT is normally constructed
- from a Base PDU by means of the REPLACE operation.
-
- The specification has the form:
-
-
-
-
-
-
-
-
-
-
-
-
- For the conventions of value assignments see section A.4.6.
-
- Example:
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- To construct invalid components in test PDUs to be sent by the
- tester, the abstract REDEFINE operation is sometimes used. It is
- used together with the REPLACE operation in the following form:
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- The scope of the newly defined type is restricted to the PDU
- definition containing the REDEFINE operation.
-
- Note that if the <value> is a reference to an element defined
- elsewhere (i.e. a TSP or a Library Component), then the new type
- definition does not affect the referenced element itself but only
- its usage in the actual PDU.
-
- Example:
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- The error to be constructed here is the wrong tag of the ORName
- type (the correct tag would be [APPLICATION 0]). The scope of the
- erroneous type-definition constructed by "REDEFINE" is restricted
- to all occurrences of ORName in the definition of IM_UAPDU_1_3.
- This means that L_ORDescriptor_1 is used here with the modified
- ORName type, whereas the usage of this library component in other
- PDUs or components remains unaltered.
-
- A.4.4.2 Test PDUs received by the tester
-
- For received PDUs normally only a portion of the PDU relates to the
- purpose of the test.
-
- A component of interest is identified and its value assigned using
- the techniques described in A.4.3.
-
- The specification scheme has the following form:
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- Example:
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- A.4.5 Component Library
-
- Components of PDUs are defined in the library and are referenced in
- Base PDU specifications, Test PDU specifications and by other
- library components.
-
- The name of a Library Component is of the form:
-
- L_<ASN.1 type name>_<number>
-
- and is specified using the techniques described in A.4.3.
-
- Example:
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- A.4.6 Value Conventions
-
- The following conventions are used when defining values or value
- references for PDU components.
- Value references identify components defined either within the
- Component Library or within the Test Suite Parameters section.
- CharacterString Values can specified within double-quotes (eg
- "abc"); Bit String Values are specified within single-quotes (eg
- '0A'H or '0001'B; hexadecimal or binary notation); Integer Values
- are specified as numeric characters (eg 2); sets and sequences of
- values are specified within curly brackets separated by comma (eg
- {"abc",'0A'H}).
-
- For PDU's sent by the tester :
-
- [ ? ] indicates that the value has no influence on the test and
- may be anything that is legal according to the relevant
- service or protocol standard.
-
- [ - ] indicates that the parameter shall be absent.
-
- [ * ] indicates that the value is to be inserted by the tester
- before test execution.
-
- For PDU's received by the tester :
-
- [ ? ] indicates that the tester need make no verification of the
- value of the parameter .
-
- [ - ] indicates that the tester shall check that the parameter
- is absent.
-
- Note that the "?" and "-" symbols in value assignments of PDU
- components have got other meanings than "?" and "-" in generic ASP
- schedules.
-
- A.5 Test Case Identification
-
- Test cases are completely identified using four components:
-
- - a test group identifier.
- - a subgroup identifier.
- - a validity identifier.
- - a test number.
-
- These four components are specified in two equivalent ways:
-
- - As a Test Reference where the four components are textual and
- descriptive.
-
- Example:
- OriginalEncodedInfoTypeIndication/Recipient/Valid/2
-
- - As a Test Identifier where the four components are numeric and
-
-
-
-
-
-
-
-
-
-
-
- concise.
-
- Example:
- 307.2.1.2
- A.5.1 IPMS(P2) and MTS(P1) identification
-
- A.5.1.1 Test Groups
-
- Number ranges have been allocated for the test groups as shown
- below:
-
- Initial Tests 001 - 099
- X.409 Tests 100 - 199
- Protocol Elements Tests 200 - 299
- (for frequently occurring Elements)
- X.400 Service Elements Tests 300 - 399
- Additional Tests 400 - 499
-
- A.5.1.2 Subgroups
-
- Numeric identifiers have been allocated to the test subgroups as
- shown below:
-
- Originator 1
- Recipient 2
- encode 1
- decode 2
- Relay 3
- Relaying-Recipient 4
- Relaying-Originator 5
-
- A.5.1.3 Validity identifiers
-
- Test cases which exercise valid behaviour are distinguished from
- those which exercise the IUT's reaction to invalid behaviour using
- the numeric identifiers shown below:
-
- Valid 1
- Invalid 2
-

- A.6 Cross Referencing
-
- A.6.1 Cross Reference Numbering
-
- The MTS(P1) and IPMS(P2) test suites contain a cross referencing
- system for the ASPs, test PDUs and library components. The cross
- referencing appears in the left and right margins of the test suite
- as shown in Figure A-14/X.403.
-
-
-
-
-
-
-
-
-
-
-
-
-
- Figure A-14/X.403 Cross referencing.
-
- Numbers in the left hand margin of the test suite are in sequential
- order and are "place identifiers". They occur whenever an ASP, test
- PDU or library component occurs in the test suite.
-
- Whenever an ASP, test PDU or library component occurs, numbers are
- also placed in the right hand margin. These numbers are forward and
- backward references to the place identifiers of the other
- occurrences of the ASP, test PDU or library component.
-
- Where a forward or backward reference can not be found then a dot
- (".") is printed in the right hand margin. This should not occur in
- fully defined test suites.
-
- Where a line in the test suite contains more than one ASP, test PDU
- or library component, the cross references for each item in the
- line are separated by vertical bars (" ") in the right hand margin
- as shown in Figure A-15/X.403.

- A.6.2 Cross Reference Listing
-
- At the end of MTS(P1) and IPMS(P2) test suites there is a separate
- cross reference listing of all the ASPs, test PDUs and library
- components together with the place identifiers of all their
- occurrences in the test suite.
-
- Example:
- :
- :
- IM_UAPDU_1_14 586 1467
- IM_UAPDU_1_15 587 1470
- :
- :
-
- The numbers on the right side indicate the places where the item
- occurs in the test suite.

- Annex B IPMS(P2) PICS Proformas
-
- B.1 General
-
- As a prerequisite to conformance testing the supplier of an
- IPMS(P2) implementation must provide a Protocol Implementation
- Conformance Statement (PICS).
-
- The proforma IPMS(P2) PICS contained in this Annex specifies the
- information to be supplied.
-
- This information is needed for test case selection. Suppliers
- should note that tests will be performed to check that services
- shown as not supported are in fact not present rather than
- improperly implemented.
-
- The IPMS(P2) PICS is in two parts:
-
- - a part requesting information concerning the support of service
- elements,
-
- - a part requesting information concerning the support of
- protocol elements.
-
- Information on service element support is requested in tabular form
- where, for each service element,
-
- - the status of the service element is indicated as mandatory
- (M), optional (O) or not applicable (-) in columns labelled
- "STD",
-
-
-
-
-
-
-
- - the actual support of the service element by the implementation
- on origination and reception is indicated by the supplier in
- columns labelled "IMP".
-
- Information on protocol element support is requested in tabular
- form where, for each protocol element,
-
- - the status of the protocol element on origination and reception
- is indicated as mandatory (M) or optional (O) in columns
- labelled "STD",
-
- - any implementation constraints are indicated in the column
- labelled "CONST STD" where constraints are interpreted as a
- minimum for reception and a maximum for origination,
-
- - the actual support of the protocol element by the
- implementation on origination and on reception is indicated by
- the supplier in the column labelled "STATUS IMP",
-
- - the actual constraints of the implementation on origination and
- on reception is indicated by the supplier in the columns
- labelled "CONST IMP".
-
- Constraints may be expressed as a length or size (octets,
- bits,...), a value (32k-1) or a number of occurrences (4)
- depending on the element being constrained.
-
- B.2 IPMS(P2) PICS Service Elements Proforma
-
- The requirements of the X.400 Recommendations are shown in the STD
- columns of the proforma using the following keys:
-
- M : Mandatory element (X.401 Basic or Essential Optional)
- O : Optional element (X.401 Additional Optional)
- - : Not applicable service element
-
- Suppliers of an implementation should use the IMP columns in the
- proforma to specify information concerning the support of service
- elements. For convenience it is suggested that suppliers need only
- indicate with an "X" those service elements that are not supported.

- B.3 IPMS(P2) PICS Protocol Elements Proformas
-
- The requirements of the X.400 Recommendations are shown in the
- STATUS STD columns of the proformas in Tables B-2/X.403 to
- B-4/X.403 using the following keys:
-
- M : Mandatory element (X.401 Basic or Essential Optional)
- O : Optional element (X.401 Additional Optional)
-
- Protocol elements which correspond directly to service elements are
- indicated as mandatory if their corresponding service elements are
- shown in X.401 (1984) as Basic or Essential Optional, and as
- optional if their corresponding service elements are shown in X.401
- (1984) as Additional Optional. Other protocol elements are
- indicated as mandatory or optional according to their designation
- in the UAPDU definitions in X.420 (1984).
-
- The pragmatic constraints of the X.400 Implementor's Guide are
- shown in the CONST STD columns of the proformas in Tables B-2/X.403
- to B-4/X.403.
-
- Suppliers of an implementation should use:
-
- - the STATUS IMP columns in each proforma to specify information
- concerning the support of protocol elements. For convenience it
- is suggested that suppliers need only indicate with an "X" those
- protocol elements that are not supported.
-
- - the CONST IMP columns in each proforma to specify the actual
- constraints of the implementation.
