本推荐标准的目的是根据SLE参考模型（参考文献[1]）定义空间链路扩展（SLE）返回操作控制场（ROCF）服务。ROCF服务是一种SLE传输服务，从一个主通道或一个虚拟通道向任务用户提供所有操作控制字段。交叉引用:CCSDS 911.5-B-2CCSDS 910.4-B-2CCSDS 131.0-B-1CCSDS 132.0-B-1CCSDS 232.0-B-1CCSDS 732.0-B-2CCSDS 133.0-B-1CCSDS 301。 0-B-3ISO/IEC 8824-1:2002CCSDS 202.0-B-3CCSDS 913.1-B-1CCSDS A00。0-Y-9CCSDS 910.3-G-3CCSDS 101.0-B-6-SCCSDS 102.0-B-5-SCCSDS 202.0-B-3-SCCSDS 701.0-B-3-SCCSDS 913.1-B-1购买本文件时提供的所有当前修改件均包含在购买本文件中。

The purpose of this Recommended Standard is to define the Space Link Extension (SLE) Return Operational Control Fields (ROCF) service in conformance with the SLE Reference Model (reference [1]). The ROCF service is an SLE transfer service that delivers to a mission user all operational control fields from one master channel or one virtual channel.Cross References:CCSDS 911.5-B-2CCSDS 910.4-B-2CCSDS 131.0-B-1CCSDS 132.0-B-1CCSDS 232.0-B-1CCSDS 732.0-B-2CCSDS 133.0-B-1CCSDS 301.0-B-3ISO/IEC 8824-1:2002CCSDS 202.0-B-3CCSDS 913.1-B-1CCSDS A00.0-Y-9CCSDS 910.3-G-3CCSDS 101.0-B-6-SCCSDS 102.0-B-5-SCCSDS 202.0-B-3-SCCSDS 701.0-B-3-SCCSDS 913.1-B-1All current amendments available at time of purchase are included with the purchase of this document.
