ISO 22669:2007 defines the space link extension (SLE) return-all-frames (RAF) service in conformance with ISO 15396:1998. The RAF service is an SLE transfer service that delivers to a mission user all telemetry frames from one space link physical channel. ISO 22669:2007 defines, in an abstract manner, the RAF service in terms of the operations necessary to provide the 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 acquire telemetry frames from signals received from a spacecraft; the methods or technologies required to provide a suitable environment for communications; or the management activities required to schedule, configure, and control the RAF service.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
This second edition cancels and replaces the first edition (ISO 22669:2003), which has been technically
revised.
ISO 22669 was prepared by the Consultative Committee for Space Data Systems (CCSDS) (as
CCSDS 911.1-B-2, November 2004) and was adopted (without modifications except those stated in Clause 2
of this International Standard) by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee
SC 13, Space data and information transfer systems.

CCSDS RECOMMENDATION FOR SLE RETURN ALL FRAMES SERVICE
STATEMENT OF INTENT
The Consultative Committee for Space Data Systems (CCSDS) is an organization officially
established by the management of member space Agencies. The Committee meets
periodically to address data systems problems that are common to all participants, and to
formulate sound technical solutions to these problems. Inasmuch as participation in the
CCSDS is completely voluntary, the results of Committee actions are termed
Recommendations and are not considered binding on any Agency.
This Recommendation is issued by, and represents the consensus of, the CCSDS Plenary
body. Agency endorsement of this Recommendation is entirely voluntary. Endorsement,
however, indicates the following understandings:
o Whenever an Agency establishes a CCSDS-related standard, this standard will be in
accord with the relevant Recommendation. Establishing such a standard does not
preclude other provisions which an Agency may develop.
o Whenever an Agency establishes a CCSDS-related standard, the Agency will provide
other CCSDS member Agencies with the following information:
-- The standard itself.
-- The anticipated date of initial operational capability.
-- The anticipated duration of operational service.
o Specific service arrangements shall be made via memoranda of agreement. Neither this
Recommendation nor any ensuing standard is a substitute for a memorandum of
agreement.
No later than five years from its date of issuance, this Recommendation will be reviewed by
the CCSDS to determine whether it should: (1) remain in effect without change; (2) be
changed to reflect the impact of new technologies, new requirements, or new directions; or,
(3) be retired or canceled.
In those instances when a new version of a Recommendation is issued, existing CCSDS-
related Agency standards and implementations are not negated or deemed to be non-CCSDS
compatible. It is the responsibility of each Agency to determine when such standards or
implementations are to be modified. Each Agency is, however, strongly encouraged to direct
planning for its new standards and implementations towards the later version of the
Recommendation.

CCSDS RECOMMENDATION FOR SLE RETURN ALL FRAMES SERVICE
FOREWORD
This document is a technical Recommendation for use in developing ground systems for
space missions and has been prepared by the Consultative Committee for Space Data
Systems (CCSDS). The Space Link Extension Return All Frames Service described herein
is intended for missions that are cross-supported between Agencies of the CCSDS.
This Recommendation specifies a data service that extends certain of the space-to-ground
communications services previously defined by CCSDS (references [2], [3], and [4]) within
the framework established by the CCSDS Space Link Extension Reference Model (reference
[1]). It allows implementing organizations within each Agency to proceed with the
development of compatible, derived Standards for the ground systems that are within their
cognizance. Derived Agency Standards may implement only a subset of the optional
features allowed by the Recommendation and may incorporate features not addressed by the
Recommendation.
Through the process of normal evolution, it is expected that expansion, deletion or
modification to this document may occur. This Recommendation is therefore subject to
CCSDS document management and change control procedures, as defined in the Procedures
Manual for the Consultative Committee for Space Data Systems. Current versions of
CCSDS documents are maintained at the CCSDS Web site:
http://www.ccsds.org/
Questions relating to the contents or status of this document should be addressed to the
CCSDS Secretariat at the address indicated on page i.

CCSDS RECOMMENDATION FOR SLE RETURN ALL FRAMES SERVICE
1 INTRODUCTION
1.1 PURPOSE OF THIS RECOMMENDATION
The purpose of this Recommendation is to define the Space Link Extension (SLE) Return All
Frames (RAF) service in conformance with the SLE Reference Model (reference [1]). The
RAF service is an SLE transfer service that delivers to a mission user all telemetry frames
from one space link physical channel.
1.2 SCOPE
This Recommendation defines, in an abstract manner, the RAF service in terms of:
a) the operations necessary to provide the 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 acquire telemetry frames from signals
received from a spacecraft;
d) the methods or technologies required to provide a suitable environment for
communications; or
e) the management activities required to schedule, configure, and control the RAF service.
1.3 APPLICABILITY
1.3.1 APPLICABILITY OF THIS RECOMMENDATION
This Recommendation provides a basis for the development of real systems that implement
the RAF service. Implementation of the RAF service in a real system additionally requires
the availability of a communications service to convey invocations and returns of RAF
service operations between RAF service users and providers. This Recommendation requires
that such a communications service must ensure that invocations and returns of operations
are transferred:
a) in sequence;
CCSDS 911.1-B-2 Page 1-1 November 2004
© ISO 2007 – All rights reserved 13
---------------------- Page: 16 ----------------------
ISO 22669:2007(E)
CCSDS RECOMMENDATION FOR SLE RETURN ALL FRAMES SERVICE
b) completely and with integrity;
c) without duplication;
d) with flow control that notifies the application layer in the event of congestion; and
e) with notification to the application layer in the event that communications between
the RAF service user and the RAF service provider are disrupted, possibly resulting
in a loss of data.
It is the specific intent of this Recommendation to define the RAF service in a manner that is
independent of any particular communications services, protocols, or technologies.
1.3.2 LIMITS OF APPLICABILITY
1.3.2.1 Relationship to Real Systems
This Recommendation specifies the RAF service that may be provided by an SLE Complex
for inter-Agency cross support. It is neither a specification of, nor a design for, real systems
that may be implemented for the control and monitoring of existing or future missions.
1.3.2.2 RAF Service and Telemetry Channel Coding
Telemetry channel coding on the space link is specified by reference [2]. This specification
is more restrictive with respect to telemetry channel coding than is reference [2]. In
particular, the provision of RAF service requires that Reed-Solomon coding must be present
or absent on all frames of a physical channel. RAF service is not supported where there is a
concurrent mix, on one physical channel, of some frames with Reed-Solomon coding and
some frames without.
1.4 RATIONALE
The goal of this Recommendation is to create a standard for interoperability between the
tracking stations or ground data handling systems of various Agencies and the consumers of
spacecraft telemetry.
1.5 DOCUMENT STRUCTURE
1.5.1 ORGANIZATION
This document is organized as follows:
a) section 1 presents the purpose, scope, applicability and rationale of this
Recommendation and lists the definitions, conventions, and references used
throughout the Recommendation;

ISO 22669:2007(E)
CCSDS RECOMMENDATION FOR SLE RETURN ALL FRAMES SERVICE
b) section 2 provides an overview of the RAF service including a functional description,
the service management context, and protocol considerations;
c) section 3 specifies the operations of the RAF service;
d) section 4 specifies the dynamic behavior of the RAF service in terms of the state
transitions of the RAF service provider;
e) annex A provides a formal specification of RAF service data types using Abstract
Syntax Notation One (ASN.1);
f) annex B lists all terms used in this Recommendation and identifies where they are
defined;
g) annex C lists all acronyms used within this document;
h) annex D provides a conformance matrix that defines what capabilities must be
provided for an implementation to be considered compliant with this
Recommendation;
i) annex E provides a list of informative references.
1.5.2 SLE SERVICES DOCUMENTATION TREE
This Recommendation is based on the cross support model defined in the SLE Reference
Model (reference [1]). It expands upon the concept of an SLE transfer service as an
interaction between an SLE Mission User Entity (MUE) and an SLE transfer service
provider for the purpose of providing the RAF transfer service.
This Recommendation is part of a suite of documents specifying the SLE services. The SLE
services constitute one of the three types of Cross Support Services:
a) Part 1: SLE Services;
b) Part 2: Ground Domain Services;
c) Part 3: Ground Communications Services.
The basic organization of the SLE services documentation is shown in figure 1-1. The
various documents are described in the following subsections.
