NBN ISO 22671:2022

This Recommended Standard defines, in an abstract manner, the Forward CLTU service in
terms of:
a) the operations necessary to provide the transfer service;
b) the parameter data associated with each operation;
c) the behaviors that result from the invocation of each operation; and
d) the relationship between, and the valid sequence of, the operations and resulting
behaviors.
It does not specify:
a) individual implementations or products;
b) the implementation of entities or interfaces within real systems;
c) 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;
d) the methods or technologies required for communications; or
e) the management activities necessary to schedule, configure, and control the Forward
CLTU service.
