付费计量系统的标准化框架（下）

1.4 系统实体和接口 System entities and interfaces

1.4.1 概述（General）

        See Clause 13 for a more complete description and definition of system entities and
interfaces.
        见第 13 条有更完整的系统实体和接口的描述和定义。

1.4.2 CIS 客户信息系统 CIS: （Customer_Information_System）

        See 13.1 for a more complete description and definition of the customer information systems.Customer information systems should be defined in terms of data elements, functions,
processes and interfaces within the context of the system as defined in this framework.
        见图13.1有更完整的CIS的描述和定义CIS应该根据框架中整个系统的数据单元、功能、过程和接口进行定义。 

1.4.3 CIS和POS接口 （CIS_to_POS_Interface）

        See 13.2 for a more complete description and definition of this interface.
Interfaces should be defined in terms of data elements, functions and processes within the
context of the system as defined in this framework.
It should be structured as an application layer and a physical layer in terms of the OSI
reference model with optionally one or more intermediate layers. Functions and data formats
are defined in each of the layers.
        见图13.2有更完整的接口描述和定义，接口应该根据框架中整个系统的数据单元、功能和过程来定义。应该根据OSI标准模块中任意一个或多个中间层来构造应用层和物理层。应该在每层中定义功能和数据格式。 

1.4.4 POS：销售点 （POS: Point_Of_Sale）

        See 13.3 for a more complete description and definition of point of sale infrastructure.
A point of sale should be defined in terms of data elements, functions, processes and
interfaces within the context of the system as defined in this framework.
        见图13.3有POS更完整的描述和定义，销售点应该根据框架中整个系统的数据单元、功能、过程和接口进行定义 。

1.4.5 POS与TOKEN载体接口（POS_to_Token_Carrier_Interface）

        See 13.4 for a more complete description and definition of this interface.Interfaces should be defined in terms of data elements, functions and processes within the context of the system as defined in this framework.It should be structured as an application layer and a physical layer in terms of the OSI reference model with optionally one or more intermediate layers. Functions and data formats are defined in each of the layers.
        见图13.4有关于该接口更完整的接口描述和定义，接口应该根据框架中整个系统的数据单元、功能和过程定义，应该根据OSI标准模块中任意一个或多个中间层来构造应用层和物理层。应该在每层中定义功能和数据格式。

1.4.6 TOKEN载体 （Token_Carrier）

        See 13.5 for a more complete description and definition of token carriers.A token carrier should be defined as the medium in the physical layer of the POS_to_Token_Carrier_Interface and the Token_Carrier_to_Meter_Interface within the context of the system as defined in this framework.
        NOTE In some two-way virtual token carrier based systems, there may be also a CIS_to_Token_Carrier_Interface for the remote communication services involved.
        见图13.5有关于TOKEN载体更完整的描述和定义
TOKEN载体在框架中的整个系统中，应该定义为在POS和TOKEN载体接口和TOKEN载体和表
计接口之间的的物理层中的媒介。 

1.4.7 TOKEN载体与表计接口（Token_Carrier_to_Meter_Interface）

        See 13.6 for a more complete description and definition of this interface.
Interfaces should be defined in terms of data elements, functions and processes within the
context of the system as defined in this framework.
It should be structured as an application layer and a physical layer in terms of the OSI
reference model with optionally one or more intermediate layers. Functions and data formats
are defined in each of the layers.
        见图13.6有更完整的接口描述和定义，接口应该根据框架中整个系统的数据单元、功能和过程定义应该根据OSI标准模块中任意一个或多个中间层来构造应用层和物理层。应该在每层中定义功能和数据格式。

1.4.8 付费表计（Payment_Meter）

        See 13.7 for a more complete description and definition of payment meters.
Payment meters should be defined in terms of data elements, functions, processes and
interfaces within the context of the system as defined in this framework.
        见图 13.7 有更完整的付费表计的定义和描述，付费表计应该根据应该根据框架中整个系统的数据单元、功能、过程和接口来定义的。
