This document defines the Communications Link Transmission Unit (CLTU) service in conformance with the transfer services specified in reference [1], Cross Support Reference Model\u2014Part 1: SLE Services<\/em>.\u00a0 The Forward CLTU service is a Space Link Extension (SLE) transfer service that enables a mission to send Communications Link Transmission Units (CLTUs) to a spacecraft.<\/p>\n

This document defines, in an abstract manner, the Forward CLTU service in terms of:<\/p>\n

    \n
  1. the operations necessary to provide the transfer service;<\/li>\n
  2. the parameter data associated with each operation;<\/li>\n
  3. the behaviors that result from the invocation of each operation; and<\/li>\n
  4. the relationship between, and the valid sequence of, the operations and resulting behaviors.<\/li>\n<\/ol>\n

    It does not specify:<\/p>\n

      \n
    1. individual implementations or products;<\/li>\n
    2. the implementation of entities or interfaces within real systems;<\/li>\n
    3. the methods or technologies required to radiate data to a spacecraft and to acquire telemetry frames from the signals received from that spacecraft for extraction of the Operational Control Field;<\/li>\n
    4. the methods or technologies required for communications; or<\/li>\n
    5. the management activities necessary to schedule, configure, and control the Forward CLTU service.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
