标准摘要
[中文适用范围]： 该国际标准是指定机载子网提供的 SOIS 兼容服务的一系列文档之一。 本国际标准定义了 SOIS 子网测试服务提供的服务和服务接口。 其范围仅指定服务，而不指定通过各种机载数据链路提供服务的方法。 本国际标准符合航天器机载接口服务绿皮书规定的原则，并拟与其一起应用。 提供此服务的协议将针对各个链接进行记录，并且根据未来的情况，这可能属于各个任务、机构或 CCSDS1 的权限。 所附 CCSDS 出版物的第 1.2 条进一步详细说明了应用范围和领域。 [外文原描述]： ISO 18438:2013 is one of a family of documents specifying the SOIS-compliant services to be provided by onboard subnetworks. ISO 18438:2013 defines services and service interfaces provided by the SOIS Subnetwork Test Service. Its scope is to specify the service only and not to specify methods of providing the service over a variety of onboard data links. ISO 18438:2013 conforms to the principles set out in the Spacecraft Onboard Interface Services Green Book and is intended to be applied together with it. The protocols which provide this service are to be documented for individual links, and this may be in the purview of individual missions, agencies, or CCSDS, depending on future circumstance.
