適用范圍：This part specifies the Virtual Terminal Protocol requirements for the support of the Virtual Terminal Functional Standard A/4113.1.1 Conformity principlesPart 1 of this Functional Standard states VT service requirements upon systems for the purpose of achieving interworking. Part 3 of this Functional Standard states ACSE, Presentation, syntax and Session requirements upon systems for the purpose of achieving interworking.This part of this Functional Standard states requirements on the Virtual Terminal Protocol for the purpose of achieving interworking. Section 1.2 states the relationship between these requirements and those of the base standard. In addition, any supplier claiming conformity shall make available a statement of support or non-support of each recommendation identified in the Functional Standard.1.2 Relationship With Base StandardTo conform to the VT Protocol used in this Functional Standard, implementations shall implement all the supported (s) features identified in the tables of clauses 3-5 of this part of this Functional Standard and shall state which optionally supported (os) features are implemented.Claims of conformity shall be defined in terms of clause 13 of ISO 9041.1.3 Relationship to the VT PICS ProformaThe tables in this part of this Functional Standard are based upon the tables of the VT PICS proforma (ISO 9041 -2). To aid cross reference with that document, the table numbering is the same. Since not all VTPDUs are supported some tables contained in the PICS proforma are missing from this part of this Functional Standard.NOTE - this document is based on the version of tie ISO VT PICS Proforma current at the time. An update is likely to be necessary when the ISO work reaches full IS status.
