标准简介：This International Standard defines the communications link transmission unit (CLTU) service in conformance
with the transfer services specified in ISO 15396:1998. 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.
This International Standard defines, in an abstract manner, the forward CLTU service in terms of
- the operations necessary to provide the transfer service;
- the parameter data associated with each operation;
- the behaviors that result from the invocation of each operation; and
- the relationship between, and the valid sequence of, the operations and resulting behaviors.
It does not specify
- individual implementations or products;
- the implementation of entities or interfaces within real systems;
- 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;
- the methods or technologies required for communications; or
- the management activities necessary to schedule, configure, and control the forward CLTU service.
The scope and field of application are furthermore detailed in subclause 1.3 of the enclosed CCSDS
publication.
