kSIST prES 202 336-6 V1.1.1:2012 is the SIST version of ETSI ES 202 336-6, part of the Environmental Engineering (EE) series for monitoring and control interfaces for infrastructure equipment. It specifies the information model for air conditioning system control and monitoring in telecommunication networks, including the data to exchange, the XML structure, and the distinction between systems with and without chillers. It is aimed at people who design, integrate, supervise, or procure telecommunication support systems.
What does kSIST prES 202 336-6 V1.1.1:2012 specify?
kSIST prES 202 336-6 V1.1.1:2012 specifies the monitoring and control information model for air conditioning systems used with telecommunication equipment. The document focuses on the data needed at the interface, how that data is grouped, and how it is encoded in XML.
The scope covers air conditioning systems for telecommunication installations and equipment. Field bus is outside the scope of this multi-part deliverable.
The document is organized into a short main body and four annexes:
| Annex | What it covers |
|---|---|
| Annex A | Mandatory monitoring and supervision information and functions |
| Annex B | Non-mandatory monitoring and supervision information and functions |
| Annex C | Mandatory XML structure and elements |
| Annex D | Bibliography |
The main clauses set out the scope, references, definitions and abbreviations, and the description of air conditioning system types. The annexes then turn that description into tables and XML structures that can be used in implementation.
What are the key requirements of kSIST prES 202 336-6 V1.1.1:2012?
kSIST prES 202 336-6 V1.1.1:2012 defines what information an air conditioning system shall or should provide for remote supervision, and it separates the mandatory information from the additional information. In practice, that means a designer or integrator can use the document to decide what must be reported, what may be added, and how the result is structured in XML.
The document defines two monitored system families
Clause 4 describes air conditioning systems without chillers and with chillers. The “without chillers” family includes variants such as direct cooling, thermoelectric cooler, heat exchanger, and membrane cooling.
This matters because the monitoring points differ by system type. A purchaser or integrator needs to know whether the installation includes compressors, condensers, pumps, cooling coils, or only fan and temperature-control functions.
Mandatory information is listed in Annex A
Annex A gives the mandatory monitoring and supervision information for both system families. It organizes the data into alarm, event, data, data record, config, and control information.
In practice, Annex A is the minimum set that should be supported for remote monitoring. It includes items such as fan failure, temperature sensor failure, high temperature, electrical circuit protective device failure, runtime counters, energy consumption, threshold parameters, and remote control functions.
Optional information is listed separately in Annex B
Annex B provides non-mandatory information that adds value beyond the minimum set. It includes extra alarms, data items, records, configuration items, and controls for both system families.
This helps when a site needs richer diagnostics or better trend analysis. For example, the additional items include low temperature, low and high humidity, power failure, differential pressure, fan speed, and estimated autonomy.
The document distinguishes alarms, events, data, config, and control
The tables in Annex A and Annex B use several functional categories. Alarms cover abnormal states, events cover state changes that are not alarms, data covers measured values and counters, config covers setpoints and thresholds, and control covers remote actions.
This structure is important because it tells implementers how each item should behave in the management interface. For example, a threshold belongs in config, a measured room temperature belongs in data, and a scheduled heating or cooling command belongs in control.
The source of information is defined
Annex A states that the information shall be provided by the Control Unit (XCU). If there is no XCU, the Data Gathering Unit (DGU) should provide the data.
That matters for system architecture and procurement. It tells the buyer which unit is expected to expose the monitoring data and which unit may need to store measurements and log files.
The XML model is standardized in Annex C
Annex C defines the mandatory XML structure and elements for an air conditioning system. The air conditioning system appears as a child of a site energy system in the site DGU XML structure, and the XCU generates an air_conditioning_system.xml file that can be embedded in site.xml.
This is the practical output of the standard. It lets software developers and integrators build interoperable XML files for supervision systems and for embedding equipment data into site-level documents.
Environmental limits and generic identifiers come from the companion framework
The document uses the generic interface in ETSI ES 202 336-1 and refers to ETSI EN 300 019 for environmental conditions and tests. The annex tables also point to the identifiers and XML parameters defined in ES 202 336-1.
This means the air conditioning model is not standalone. It follows the generic monitoring structure and uses the same naming and parameter concepts as the wider ETSI monitoring framework.
What terms does kSIST prES 202 336-6 V1.1.1:2012 define?
- Air conditioner - An encased assembly designed to deliver conditioned air to an enclosed space, and it may cool, dehumidify, heat, circulate, clean, or humidify the air.
- Alarm - Information that signals an abnormal state such as a hardware fault, software fault, or environmental condition outside normal values.
- Control Unit (CU) - An integrated unit in equipment that monitors and controls the equipment through sensors and actuators.
- Data Gathering Unit (DGU) - A unit that collects data, can send commands, and mediates between equipment interfaces and management protocols.
- eXtensible Mark-up Language (XML) - A restricted form of SGML used here to describe the air conditioning monitoring data in a structured file.
- XCU - A CU enabled to communicate using the XML interface defined in this document.
- XML Schema Definition (XSD) - A more detailed XML description method than DTD, mentioned as a related XML concept in the definitions.
- Miniature Circuit Breaker (MCB) - An abbreviation used in the tables for a protective device whose trip or failure can be monitored.
Who uses kSIST prES 202 336-6 V1.1.1:2012?
kSIST prES 202 336-6 V1.1.1:2012 is used by people who specify, build, integrate, or operate monitoring for telecom site cooling systems. That includes equipment manufacturers, control-unit and DGU implementers, telecom infrastructure operators, and maintainers of remote management systems.
It is particularly relevant for work on:
- telecommunication equipment rooms and cabinets
- power and cooling infrastructure at telecom sites
- remote supervision applications
- XML-based management interfaces
- alarm, event, and measurement integration
It also helps quality and procurement teams define what information a cooling system must provide before acceptance or deployment.
Which standards are used with kSIST prES 202 336-6 V1.1.1:2012?
- ETSI ES 202 336-1 - Provides the generic monitoring and control interface framework, including the common terms, identifiers, and XML parameter concepts used by this part.
- ETSI EN 300 019 (all parts) - Provides the environmental conditions and environmental tests used when the tables refer to ETSI absolute maximum ranges.
- ETSI TR 102 336 - Gives guidance on power and cooling system control and monitoring, and is cited as a companion reference for the air conditioning system subset.
- IEEE 802.1 to 802.11 - Supports the definition of Ethernet in the document’s terminology.
- ISO/IEC 8879 - Supports the definition of SGML, which underlies XML in the terminology section.
What does the kSIST prES 202 336-6 V1.1.1:2012 document contain?
The document contains text tables, XML structure definitions, and annexes that map air conditioning supervision needs into machine-readable data. The tables in Annex A and Annex B separate alarms, events, data, data records, configuration items, and control items for both system families.
It also contains a structural XML example in Annex C showing where the air conditioning system sits inside the site-level XML hierarchy. That structure is used for DGU and XCU implementation, file embedding, and system integration.
Figures 1 and 2 show the two main air conditioning system arrangements, without chillers and with chillers. The clause text around those figures explains the components involved, such as fans, sensors, pumps, compressors, condensers, cooling coils, and water or fluid circuits.
The document further includes definitions, abbreviations, a bibliography, and history information. Together, these parts support design, implementation, supervision, and documentation of telecom cooling monitoring interfaces.

For the purposes of the present document, the following terms and definitions apply:
air conditioner: encased assembly or assemblies designed as an appliance to provide delivery of conditioned air to an
enclosed space, room or zone
NOTE: It includes an electrically operated refrigeration system for cooling and possibly dehumidifying the air. It
may have means for heating, circulating, cleaning and humidifying the air.
alarm: any information signalling abnormal state, i.e. different to specified normal state of hardware, software,
environment condition (temperature, humidity, etc.)
NOTE: The alarm signal should be understood by itself by an operator and should always have at least one
severity qualification or codification (colour, level, etc.). Example: fan failure, temperature low, …).
alarm loop: electrical loop which open or closed state correspond to alarm start (set) or end (clear) state
alarm message: text parts of the alarm structure
alarm structure: organized set of information fields in an alarm data frame (time stamp, set/clear, text, etc.)

actuators
Control form Style Sheet (CSS): simple mechanism for adding style (e.g. fonts, colours, spacing) to Web documents
EXAMPLE: Tutorials, books, mailing lists for users, etc.
Data Gathering Unit (DGU): functional unit used for several functions:
• collect serial, digital, and analogue data from several equipment;
• option to send (output) serial or digital commands;
• forward/receive information to/from the Local/Remote Management Application via agreed protocols;
• mediation between interfaces and protocols.
NOTE: This function may be integrated as part of specific equipment.
Dynamic Host Control Protocol (DHCP): protocol used for self configuration of TCP/IP parameters of a workstation
assigning IP address and a sub network mask

severity qualification or codification (colour, level, etc.). It should be transmitted in a formatted structure
with text message and other fields like for alarm, e.g. an event can be coded as an alarm with severity "0".
ETSI
7 Final draft ETSI ES 202 336-6 V1.1.1 (2012-07)
eXtensible Mark-up Language (XML): application profile or restricted form of SGML
NOTE: By construction, XML documents are conforming SGML the Standard Generalized Markup Language
(ISO/IEC 8879 [i.3]). XML is designed to describe data and focus on what data is. XML is discerned
from the well known Hypertext Transfer Mark-up Language (HTML) which was designed to display data
and to focus on how data looks.
eXtensible Style sheet Language (XSL): language for expressing style sheets
NOTE: It consists of two parts, a language for transforming XML documents, and an XML vocabulary for
specifying formatting semantics. An XSL style sheet specifies the presentation of a class of XML
documents by describing how an instance of the class is transformed into an XML document that uses the
formatting vocabulary.
infrastructure equipment: power, cooling and building environment systems used in telecommunications centres and
Access Networks locations
NOTE: Examples of the infrastructure equipment are cabinets, shelters, underground locations, etc.

NOTE: Selection is normally made by a keyboard, a pointing device, a mouse or directly by finger on a sensitive
screen.
object: class description of items that accept a set of properties or functions
NOTE: Generic objects can include more specific items and inherit from their properties. If correctly structured,
object programming can allow the system to evolve, i.e. be more future-proof. The code should
intrinsically be open and structured.
Hypertext Preprocessor (PHP): powerful tool for making dynamic and interactive Web pages
pop-up: information or command screen that appears when a menu choice is selected
NOTE: For example this may be a pop-up menu when the pointer is on a title button.

Simple Object Access Protocol (SOAP): way to communicate between applications running on different operating
systems, with different technologies and programming languages
NOTE: SOAP communicates over HTTP, because HTTP is supported by all Internet browsers and servers, SOAP
traffic is not blocked by firewalls and proxy servers (see W3C).
Systems Management Function (SMF): object properties or classes with projection on CMIS application context
communication
NOTE: Set of ISO system management functions according to ISO/IEC 10164 [i.2].
warning: low severity alarm
web: common name for the Internet or Intranet

Figure 1: Air conditioning system (without chillers)
Figure 2: Air conditioning system (with chillers)
NOTE: The Cooling coil shown in figure 2 may be part of a Direct Expansion chiller circuit (as shown) or could
be supplied with chilled water from a remotely sited centralized cooling plant.
The main function of air conditioning systems is to use the temperature control system (such as fans, compressor
chillers or water-cooling device) to control the telecom system environment (including the equipment room and
equipment cabinets) at the appropriate humidity and temperature.
Air conditioning systems without chillers as depicted in figure 1 usually include the following main components:
• System controller unit e.g. XCU
• Cooling fan(s)

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
air conditioner: encased assembly or assemblies designed as an appliance to provide delivery of conditioned air to an
enclosed space, room or zone
NOTE: It includes an electrically operated refrigeration system for cooling and possibly dehumidifying the air. It
may have means for heating, circulating, cleaning and humidifying the air.
alarm: any information signalling abnormal state, i.e. different to specified normal state of hardware, software,
environment condition (temperature, humidity, etc.)
NOTE: The alarm signal should be understood by itself by an operator and should always have at least one
severity qualification or codification (colour, level, etc.). Example: fan failure, temperature low, …).
alarm loop: electrical loop which open or closed state correspond to alarm start (set) or end (clear) state
alarm message: text parts of the alarm structure
alarm structure: organized set of information fields in an alarm data frame (time stamp, set/clear, text, etc.)
Control form Style Sheet (CSS): simple mechanism for adding style (e.g. fonts, colours, spacing) to Web documents
EXAMPLE: Tutorials, books, mailing lists for users, etc.
Control Unit (CU): integrated unit in an equipment to monitor and control this equipment through sensors and
actuators
Data Gathering Unit (DGU): functional unit used for several functions:
• collect serial, digital, and analogue data from several equipment;
• option to send (output) serial or digital commands;
• forward/receive information to/from the Local/Remote Management Application via agreed protocols;
• mediation between interfaces and protocols.
NOTE: This function may be integrated as part of specific equipment.
Ethernet: LAN protocol
NOTE: Equivalent to IEEE 802.1 to 11 [i.1].
event: any information signalling a change of state which is not an alarm: e.g. battery test, change of state of battery
charge
NOTE: The event signal should be understood by itself by an operator and should always have at least one
severity qualification or codification (colour, level, etc.). It should be transmitted in a formatted structure
with text message and other fields like for alarm, e.g. an event can be coded as an alarm with severity "0".
eXtensible Mark-up Language (XML): application profile or restricted form of SGML
NOTE: By construction, XML documents are conforming SGML the Standard Generalized Markup Language
(ISO/IEC 8879 [i.2]). XML is designed to describe data and focus on what data is. XML is discerned
from the well known Hypertext Transfer Mark-up Language (HTML) which was designed to display data
and to focus on how data looks.
ETSI
7 ETSI ES 202 336-6 V1.1.1 (2012-09)
eXtensible Style sheet Language (XSL): language for expressing style sheets
NOTE: It consists of two parts, a language for transforming XML documents, and an XML vocabulary for
specifying formatting semantics. An XSL style sheet specifies the presentation of a class of XML
documents by describing how an instance of the class is transformed into an XML document that uses the
formatting vocabulary.
infrastructure equipment: power, cooling and building environment systems used in telecommunications centres and
Access Networks locations
NOTE: Examples of the infrastructure equipment are cabinets, shelters, underground locations, etc.
intranet: internal company network generally using Ethernet protocol and extended IP addresses
menu: list of possible input command choices that may be presented in different ways on a display
NOTE: Selection is normally made by a keyboard, a pointing device, a mouse or directly by finger on a sensitive
screen.
object: class description of items that accept a set of properties or functions
NOTE: Generic objects can include more specific items and inherit from their properties. If correctly structured,
object programming can allow the system to evolve, i.e. be more future-proof. The code should
intrinsically be open and structured.
Simple Object Access Protocol (SOAP): way to communicate between applications running on different operating
systems, with different technologies and programming languages
NOTE: SOAP communicates over HTTP, because HTTP is supported by all Internet browsers and servers, SOAP
traffic is not blocked by firewalls and proxy servers (see W3C).
warning: low severity alarm
web: common name for the Internet or Intranet
World Wide Web Consortium (W3C): consortium founded in October 1994 to develop common interoperable
protocols and promote World Wide Web
NOTE: See http://www.w3c.org.
XCU: CU enabled to communicate using XML interface as defined in the present document
XML Schema Definition (XSD): new more detailed XML description compared to the previous one, the DTD

4 Air conditioning systems
The Air conditioning system subset is described in ES 202 336-1 [1] and TR 102 336 [i.3].
The Air conditioning systems addressed by the present document are depicted in figures 1 and 2. One single control unit
XCU can monitor and control several air conditioning systems through field bus. Field bus is outside the scope of this
multi-part deliverable.

NOTE: The Cooling coil shown in figure 2 may be part of a Direct Expansion chiller circuit (as shown) or could
be supplied with chilled water from a remotely sited centralized cooling plant.
The main function of air conditioning systems is to use the temperature control system (such as fans, compressor
chillers or water-cooling device) to control the telecom system environment (including the equipment room and
equipment cabinets) at the appropriate humidity and temperature.
Air conditioning systems without chillers as depicted in figure 1 usually include the following main components:
• System controller unit e.g. XCU
• Cooling fan(s)
• Fan monitoring unit
• Thermoelectric cooler
• Sensors
• Fresh/return air recirculation damper or actuator
Thermoelectric cooler, heat exchanger, direct Cooling and membrane cooling are four different types of air conditioning
system without chillers. All systems have a controller, cooling fan(s) and temperature/humidity sensors. Air filters,
fresh/return air recirculation damper or actuator and electric or water heat transmission medium are also normally
included. The elements of each key component are detailed below.
A fan monitoring unit includes the following elements:
• Temperature sensors
• Filters
• Control unit
A heat exchanger includes the following elements:
• Fans
• Temperature sensors
• Heat exchange core
• Control unit
• Heater
A membrane cooling system includes the following elements:
