CROSS SUPPORT TRANSFER SERVICES—MONITORED DATA SERVICE
1 INTRODUCTION
1.1 PURPOSE OF THIS RECOMMENDED STANDARD
This Recommended Standard defines the Monitored Data Cross Support Transfer Service
(CSTS), in conformance with the Cross Support Transfer Services Specification Framework
Recommended Standard (reference [1]). The Monitored Data CSTS (MD-CSTS) is a service
that allows a spaceflight mission to receive cyclic reports on, and to query the current values
of, the parameters that are pertinent to Cross Support Services being provided by a Cross
Support Complex. The Monitored Data service also allows a spaceflight mission to receive
notifications of the occurrence of events of interest associated with the services that are being
provided by a Cross Support Complex.
NOTE – The term ‘Cross Support Complex’, as used throughout this document,
corresponds to the Earth Space Link Terminal (ESLT) defined in the Space
Communications Cross Support Architecture Description Document
(reference [G9]).
1.2 SCOPE
This Recommended Standard defines the Monitored Data service in terms of:
a) the CSTS procedures that constitute the service;
b) the extensions and refinements of the behavior of those CSTS procedures necessary
to provide the transfer service;
c) the extensions and refinements of standard CSTS operations associated with each of
the procedures;
d) the relationships among the procedures that constitute the service.
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 measure the values of monitored parameters
and to detect the occurrence of events of interest;
d) the methods or technologies required for communication;
e) the management activities necessary to schedule, configure, and control the MD-
CSTS;
f) the specific parameters that are to be reported and events that are to be notified by the
MD-CSTS.

CROSS SUPPORT TRANSFER SERVICES—MONITORED DATA SERVICE
1.3 APPLICABILITY
1.3.1 GENERAL
The applicability and limits of applicability of Cross Support Transfer Services in general, as
described in reference [1], pertain to the Monitored Data service, with the addition of the
conditions described in 1.3.2, below.
1.3.2 APPLICABILITY OF THIS RECOMMENDED STANDARD
This Recommended Standard is applicable to the implementation of real systems that
monitor provision and production of space communication Cross Support Services for the
purposes of generating cyclic status reports, generating notifications of changes in status in
real time, and responding to queries of current values of operational parameters.
1.4 RATIONALE
The goal of this Recommended Standard is to create a standard for interoperability for the
exchange of cross support service-related status information between the cross support
elements of various space Agencies and the users of the Cross Support Services that they
provide.
1.5 DOCUMENT ORGANIZATION
Section 2 describes the Monitored Data Cross Support Transfer Service in terms of:
– the role of Service Management with respect to the MD-CSTS;
– the allocation of production and provision of the MD-CSTS to Functional Resources;
– the cross support view of the MD-CSTS;
– the functional description of the production and provision of the service; and
– an operational scenario that illustrates some of the more significant aspects of the
service.
Section 3 specifies the composition of the MD-CSTS. The service type identifier is declared,
the procedures that constitute the service are identified, and the CSTS state machine that
applies to the MD-CSTS is specified. Because the MD-CSTS is composed of procedures that
are directly adopted from the CSTS Framework without extension, no further specification of
the MD-CSTS is required.
Section 4 specifies the On-Change-Option Cyclic Report procedure, which is an extension
and refinement of the Framework Cyclic Report Procedure.
Section 5 specifies the refinements of the Information Query procedure.

ISO 23104:2020(E)
CROSS SUPPORT TRANSFER SERVICES—MONITORED DATA SERVICE
Section 6 specifies the refinements of the Notification procedure.
Section 7 specifies how the procedure configuration parameters are to be set for the MD-
CSTS.
Section 8 specifies the Monitored Data Service-specific versions of the service-generic
parameter and events that are defined in Cross Support Transfer Service—Specification
Framework (reference [1]).
Section 9 specifies the refinements of the definitions of Framework parameters, events, and
directives for the purposes of making them applicable to the MD-CSTS.
Annex A is the Implementation Conformance Statement Proforma for the MD-CSTS.
Annex B provides the formal specification of the ASN.1 Object Identifiers module for the
Monitored Data transfer service.
Annex C provides the formal specification of the ASN.1 Protocol Data Unit module for the
On-Change-Option Cyclic Report procedure of the Monitored Data transfer service.
Annex D defines the monitored data production process. In particular, it specifies how
monitored data values are to be labeled so that, when transferred by MD-CSTS instances, the
sources of the measurements are unambiguous.
Annex E addresses the security, Space Assigned Numbers Authority (SANA), and patent
considerations associated with the MD-CSTS.
Annex F describes an example set of monitored parameters, notifiable events, and their
associated Functional Resource Types. These examples are modeled on the contents of the
SANA Functional Resource Registry (reference [3]).
NOTE – The SANA Functional Resource Registry is the normative repository of all such
definitions. The example entries in annex F are included to illustrate the concepts
of the use of Functional Resources by the MD service. Any real implementation
of the MD service must use the Functional Resource specifications found in the
SANA Functional Resource Registry.
Annex G provides the list of informative references.
Annex H lists the acronyms used in this document.
Annex I identifies the specific reference-[1] sections that are cross referenced by the MD-
CSTS Recommended Standard, and the sections of the MD-CSTS Recommended Standard
that reference each of those sections or subsections in reference [1]. This annex is included
for maintainability of this Recommended Standard through future changes in reference [1].

The CSTS Documentation is:
a) Cross Support Concept—Part 1: Space Link Extension Services (reference [G1]): a
Report introducing the concepts of cross support and the Space Link Extension (SLE)
services. Many of the concepts for the SLE transfer services have been adopted for
the CSTSes (see h) below);
b) Cross Support Reference Model—Part 1: Space Link Extension Services
(reference [2]): a Recommended Standard that defines the framework and

terminology for the specification of SLE services. Much of the framework and
terminology of this reference model has been adopted or adapted for CSTSes (see
1.7.2 and 2.2).
c) Space Communication Cross Support Service Management suite (informative
references [G6], [G7], and [G8]): Recommended Standards that specify the Service
Management Information Entities that are used to configure and schedule CSTSes;
d) The SLE Transfer Services suite: The SLE Transfer Services comprise a set of Cross
Support Transfer Services that are used to transfer specific telecommand and
telemetry protocol data units. The SLE Transfer Services are closely related to the
CSTS suite in that they collectively define the set of operations that are the basis for
the CSTS Specification Framework. However, because of history (the SLE Transfer
Services were already specified and implemented prior to development of the CSTS
Framework) the SLE Transfer Services are separated from CSTSes;
e) Space Link Extension - Internet Protocol for Transfer Services (reference [G2]): a
Recommended Standard that defines a protocol for transfer of Protocol Data Units
(PDUs) defined in the Cross Support Transfer Services. This Recommended Standard
was originally developed to support SLE transfer services (hence the title), but it is
also applicable to (and specified for) use by Cross Support Transfer Services.
The documents specific to Cross Support Transfer Services are:
f) Cross Support Transfer Services Specification Framework (reference [1]): a
Recommended Standard that defines basic building blocks for the specification of
Cross Support Transfer Service procedures;
g) Guideline for Specification of Cross-Support Transfer Services: a Recommended
Practice that, when published, will define the guidelines for construction of a Cross
Support Transfer Service based on the CSTS Specification Framework;
NOTE – As of the publication of this Recommended Standard, the Guidelines
Magenta Book is in-progress. It is not required to understand this
Recommended Standard.
h) Cross Support Transfer Services Specification Framework Concepts (reference [G3]):
A Report that provides tutorial material on the objectives and concepts of the CSTS
Specification Framework;
i) Cross Support Transfer Services Suite: The set of specifications for actual CSTSes
built from the procedures in the CSTS Specification Framework and in accordance
with the CSTS Guidelines.
