ETSI ES 202 336-2 V1.1.1 (2009-03) - Environmental Engineering (EE); Monitoring and control interface for infrastructure equipment (Power, Cooling and environment systems used in telecommunication networks); Part 2: DC power system control and monitoring information model
SIST ES 202 336-2 V1.1.1:2009 is the Slovenian adoption of ETSI ES 202 336-2 V1.1.1. It specifies the monitoring and control information model for DC power supply systems used in telecommunication equipment, including the data tables and XML structure used at the interface. It is meant for people who need a common way to supervise rectifiers, batteries, alarms, measurements, configuration, and control actions.
What does SIST ES 202 336-2 V1.1.1:2009 specify?
SIST ES 202 336-2 V1.1.1:2009 covers monitoring and control of DC power supply systems for telecommunication equipment. It defines the DC power system architectures that are covered, the minimum information exchanged at the interface, and the XML files that carry that information.
The document is organized around a short core and a set of annexes. Clause 1 gives the scope, clause 2 lists references, clause 3 defines terms and abbreviations, and clause 4 describes the DC power supply system model. The annexes separate mandatory content, optional content, and XML coding guidance.
| 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 | Examples of XML elements for a DC power supply system |
| Annex E | Bibliography |
What are the key requirements of SIST ES 202 336-2 V1.1.1:2009?
Clause 4 defines the DC system model and its place in the wider interface
SIST ES 202 336-2 V1.1.1:2009 treats the DC system as part of the Environmental Engineering interface family defined in Part 1. The DC system converts AC input to DC output for telecommunication sites, and it may include rectifiers, batteries, protection and distribution, and a system monitoring and control unit called the XCU. In practice, this tells implementers what equipment states, measurements, and commands must be exposed to remote supervision.
Clause 4 also notes that one XCU can monitor several power cabinets through a field bus, but the field bus itself is outside the scope of this part. That matters when designing the boundary between the local equipment and the management interface.
Annex A defines the mandatory information to be provided
Annex A is the mandatory set. For a DC power supply system without back-up, the required information includes a device description, at least one rectifier failure alarm, and a partial network failure indication, together with control functions such as program download with fallback to the previous release and reset to safe defaults.
For a DC power supply system with back-up, Annex A expands the mandatory set to cover protective devices, battery discharge, battery test failure, output low voltage, battery over-temperature, rectifier failures, mains failure, XCU reset, configuration changes, operating mode changes, measured DC voltage and currents, battery temperature, time-stamped data records, and control functions. In practice, this means the interface must support both fault reporting and the values needed to understand battery and load behavior.
Annex B adds optional information that improves supervision
Annex B lists non-mandatory data that may be provided in addition to the mandatory set. For systems without back-up, this includes dying gasp, DC bus voltage, load current, input energy consumption, power capacity management, and additive records for energy and power.
For systems with back-up, Annex B adds items such as unbalanced charge and discharge currents, unbalanced cell voltage, battery asymmetry, output overload, high output voltage, low voltage disconnect status, over-charge, mains outside input limits, battery replacement need, float voltage out of limits, earth leakage detection, battery age, estimated remaining autonomy, and battery capacity. In practice, these items support deeper diagnostics, battery health tracking, and energy reporting.
Annex B also separates data, data records, config, and control for the rectifier module. That helps vendors and operators decide which values are live measurements, which are historical records, and which are adjustable settings.
Annex C standardizes the XML structure
Annex C defines the XML organization for DC power supply data. A DC system appears as a child of a site energy system, and the XML structure groups information into tables for alarms, events, data, data records, config, control, and rectifiers. The annex also shows how a DC system can be delivered as a dc_system.xml document and then embedded in site.xml.
This matters because different products can still exchange data in a consistent way. The annex also introduces the specific element for detailed rectifier information.
Annex D gives examples of how the XML elements are used
Annex D shows example XML fragments for the main element types. It illustrates description elements for manufacturer and serial information, alarm and event elements with timestamps and severity, data elements for values such as bus voltage and load current, config elements for thresholds and operating settings, and control elements for actions such as starting battery test or switching modes.
These examples are practical guidance for software and integration work. They show how to encode the model, not just what the model contains.
What terms does SIST ES 202 336-2 V1.1.1:2009 define?
- Control Unit (CU) - An integrated unit that monitors and controls equipment through sensors and actuators.
- Data Gathering Unit (DGU) - A functional unit that collects serial, digital, and analog data and can forward information to management applications.
- XCU - An XML-enabled Control Unit that communicates through the XML interface defined in this document.
- Remote Management Application (RMA) - The supervisory application that receives the monitoring information and uses it for remote management.
- alarm - Information that signals an abnormal state, such as a hardware, software, or environmental fault.
- event - Information that signals a state change that is not an alarm, such as a battery test or charge-state change.
- data record - A logged measurement entry, used for history, trends, and records such as voltage or temperature over time.
- DTD - Document Type Definition, the XML description method used here for structuring the data model.
Who uses SIST ES 202 336-2 V1.1.1:2009?
This standard is used by telecommunication equipment manufacturers, DC power system suppliers, software developers for network management, and system integrators who need to exchange site data in a consistent XML form. It is also relevant to network operators, maintenance teams, and quality or procurement staff responsible for specifying how DC power systems are monitored and controlled.
The standard applies to telecommunication centres and access network locations that use power, cooling, and building environment systems. In practice, it supports remote supervision of rectifiers, batteries, protection devices, power measurements, alarms, and control commands.
Which standards are used with SIST ES 202 336-2 V1.1.1:2009?
- ETSI ES 202 336-1 - Provides the generic interface framework, the shared element types, and the parameter model used by this part.
- ETSI EN 300 132-2 - Defines the dc power supply interface at the input to telecommunications equipment.
- ETSI EN 300 132-3 - Defines the power supply interface for rectified current source, alternating current source, or direct current source up to 400 V.
- ETSI EN 302 099 - Covers powering of equipment in access networks.
- ETSI ES 202 336-3 to ETSI ES 202 336-7 - Give the same interface approach for AC UPS, AC distribution, diesel back-up generator, air conditioning, and other utilities systems.
What does the SIST ES 202 336-2 V1.1.1:2009 document contain?
The document contains two system figures showing a simple DC power supply system without battery back-up and a modular DC power supply system with battery back-up. It then provides text tables for mandatory and optional information sets, organized by system type and by element type such as description, alarm, event, data, data record, config, and control.
It also contains XML structure guidance for the site, energy system, DC system, and rectifier elements. Annex D adds example XML fragments for system-level and rectifier-level monitoring, settings, alarms, events, and controls.
For implementers, this means the document is useful for defining the data model, mapping measurements and alarms into XML, and checking what a DC power supervision interface should expose to a remote management system.

The main elements of DC power supply systems are:
- rectifier (one or more) that converts AC voltage to DC voltage (i.e. 230 VAC to DC voltage)
NOTE: Other alternative energy sources may be used to provide DC power e.g. Photovoltaic, wind turbine, etc.
- battery (one or more strings of cells) that stores energy and can power the loads when AC interrupts or
rectifiers fail. There can be test and permanent battery monitoring system to reduce the failure detection time
and the MTTR
- protection and distribution (DC bus, breaker …) to power different user loads and discriminate faults
- a system monitoring and control unit (XCU) to monitor voltage, current, power, temperature, etc., extend
alarms and provide system control functionality
Several measurements are possible: rectifier states, rectifier voltage and current, battery voltage, current and
temperature, user load currents …
Several controls are possible to adjust rectifier voltage and current, to optimize the load between rectifiers for energy
saving and higher reliability, to start a battery test procedure.
Table TP1 (Table Power in annex A) corresponds to mandatory data that shall be provided for a minimal DC system
without back-up, and TP1x (see annex B) includes data that should be provided in addition to mandatory one.
Table TP2 (see annex B) corresponds to mandatory data that shall be provided for a common rectifier/battery DC
system with back-up, and TP2x (see annex B) includes data that should be provided in addition to mandatory one.
Annex C standardizes XML coding structures for these data.

4 DC power supply system
The DC system subset described in ES 202 336-1 [1] transforms AC interface from mains or AC back-up engine
defined in EN 300 132-3 [3], in DC voltage on interface A defined in EN 300 132-2 [2] or EN 300 132-3 [3] for
telecom centre or defined for local or remote power supply of access network equipment in EN 302 099 [4].
The DC power systems addressed by the present document are depicted in figures 1 and 2. One single control unit XCU
can monitor and control several power cabinets through field bus. Field bus is outside the scope of the present
document.
Mandatory monitoring/ supervision information and functions are given in annex A.
Non-mandatory (optional) monitoring/ supervision information and functions are given in annex B.

The main elements of DC power supply systems are:
- Rectifier (one or more) that converts AC voltage to DC voltage (i.e. 230 VAC to DC voltage).
NOTE: Other alternative energy sources may be used to provide DC power e.g. Photovoltaic, wind turbine, etc.
- Battery (one or more strings of cells) that stores energy and can power the loads when AC interrupts or
rectifiers fail. There can be test and permanent battery monitoring system to reduce the failure detection time
and the MTTR.
- Protection and distribution (DC bus, breaker, etc.) to power different user loads and discriminate faults
- A system monitoring and control unit (XCU) to monitor voltage, current, power, temperature, etc., extend
alarms and provide system control functionality.
Several measurements are possible: rectifier states, rectifier voltage and current, battery voltage, current and
temperature, user load currents, etc.
Several controls are possible to adjust rectifier voltage and current, to optimize the load between rectifiers for energy
saving and higher reliability, to start a battery test procedure.
Table TP1 (Table Power in annex A) corresponds to mandatory data that shall be provided for a minimal DC system
without back-up, and TP1x (see annex B) includes data that should be provided in addition to mandatory one.
Table TP2 (see annex B) corresponds to mandatory data that shall be provided for a common rectifier/battery DC
system with back-up, and TP2x (see annex B) includes data that should be provided in addition to mandatory one.
Annex C standardizes XML coding structures for these data.

supplies. It specifies the mandatory requirements that must be provided in all cases.
NOTE 1: These tables do not specify the power equipment by itself. These tables refer to subsets or devices that are
not necessarily present in each equipment configuration. As a matter of fact, one alarm and its class apply
only in case of the presence of this subset or device.

3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
NOTE: Terms referring to energy interface, equipment and distribution are described in power distribution
standards EN 300 132-2 [2], EN 300 132-3 [3] for ac and dc interface and EN 302 099 [4] for access
network equipment powering.
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: rectifier failure, battery low voltage,
etc.).

Management Information Base (MIB): dynamic data base that gathers all objects and should evolve to include
automatic and manual configuration tools with self coherence tests
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.
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.
REpresentational State Transfer (REST): way to build an application for distributed system as www
ETSI
9 ETSI ES 202 336-2 V1.1.1 (2009-03)
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
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.
Windows: virtual area on the display that corresponds to a specific application
web: common name for the Internet or Intranet
XCU: CU enabled to communicate using XML interface as defined in the present document
XHTML: stricter and cleaner version of HTML. XHTML consists of all the elements in HTML 4.01 combined with
the syntax of XML. It can be read by all XML browser (see W3C)
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]). documents.XML is designed to describe data and focus on what data is. XML
should be discerned from the well known Hypertext Transfer Mark-up Language (HTML) which was
designed to display data and to focus on how data looks.
XML Schema Definition (XSD): new more detailed XML description compared to the previous one, the DTD
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.

4 DC power supply system
The DC system subset described in ES 202 336-1 [1] transforms AC interface from mains or AC back-up engine
defined in EN 300 132-3 [3], in DC voltage on interface A defined in EN 300 132-2 [2] or EN 300 132-3 [3] for
telecom centre or defined for local or remote power supply of access network equipment in EN 302 099 [4].
The DC power systems addressed by the present document are depicted in figures 1 and 2. One single control unit XCU
can monitor and control several power cabinets through field bus. Field bus is outside the scope of the present
document.
Mandatory monitoring/ supervision information and functions are given in annex A.
Non-mandatory (optional) monitoring/ supervision information and functions are given in annex B.

The main elements of DC power supply systems are:
- Rectifier (one or more) that converts AC voltage to DC voltage (i.e. 230 VAC to DC voltage).
NOTE: Other alternative energy sources may be used to provide DC power e.g. Photovoltaic, wind turbine, etc.
- Battery (one or more strings of cells) that stores energy and can power the loads when AC interrupts or
rectifiers fail. There can be test and permanent battery monitoring system to reduce the failure detection time
and the MTTR.
- Protection and distribution (DC bus, breaker, etc.) to power different user loads and discriminate faults
- A system monitoring and control unit (XCU) to monitor voltage, current, power, temperature, etc., extend
alarms and provide system control functionality.
Several measurements are possible: rectifier states, rectifier voltage and current, battery voltage, current and
temperature, user load currents, etc.
Several controls are possible to adjust rectifier voltage and current, to optimize the load between rectifiers for energy
saving and higher reliability, to start a battery test procedure.
Table TP1 (Table Power in annex A) corresponds to mandatory data that shall be provided for a minimal DC system
without back-up, and TP1x (see annex B) includes data that should be provided in addition to mandatory one.
Table TP2 (see annex B) corresponds to mandatory data that shall be provided for a common rectifier/battery DC
system with back-up, and TP2x (see annex B) includes data that should be provided in addition to mandatory one.
Annex C standardizes XML coding structures for these data.
