1 Scope
The present document applies to monitoring and control of AC distribution power systems for telecommunication or
IT equipment in telecommunications or datacenter.
The control and monitoring interface is covering:
• AC distribution boards inputs and outputs;
• AC generators (Diesel, fuel cell, renewable energy generator, etc.) outputs;
• inverter or UPS inputs and outputs.
The present document defines:
• The monitored and controlled AC distribution power system architectures.
• The minimum set of exchanged information required at the interface, described in "natural language" in text
tables.
• The XML files with tags and variables corresponding to the data in the tables.

3 Definitions and abbreviations
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 ETS 300 132-1 [2], EN 300 132-3 [3] for ac and dc interface and EN 302 099 [4] for access
network equipment powering.
AC distribution power system: device or system that distribute AC voltage or convert DC voltage to AC voltage and
provides electrical power without interruption in the event that commercial power drops to an unacceptable voltage
level
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.
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.)
battery: complete arrangement of battery cells or blocks in one string or more in parallel
battery block: battery cell (e.g. 2V for lead-acid) connected and placed in the same container (forming 4V, 6V or 12V
blocks)
battery cell: basic electrochemical element (e.g. a 2 V nominal cell for a high capacity lead acid battery)
battery string: number of serially interconnected battery blocks or cells
client post: any device (laptop, PDA, console, etc.) connected to servers via the operation system networks to perform
maintenance or supervision operations
ETSI
7 Final draft ETSI ES 202 336-4 V1.1.0 (2013-01)
Control form Style Sheet (CSS): simple mechanism for adding style (e.g. fonts, colours, spacing) to Web documents,
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 analog 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 subnetwork mask
NOTE: DHCP may also configure DNS.
Dynamic Name Server (DNS): associates a single domain name to an IP address
dynamic synoptic: dynamic display of geographical maps, networks, installations and equipment
ethernet: LAN protocol
NOTE: Equivalent to IEEE 802.1 to 802.11 [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.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.
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
EXAMPLE: Cabinets, shelters, underground locations, etc.
intranet: internal company network generally using Ethernet protocol and extended IP addresses
logbook: chronological file that contains alarm and event messages may be paper or electronic
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
ETSI

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
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
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
Windows: virtual area on the display that corresponds to a specific application
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
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 browsers (see W3C)
XML Schema Definition (XSD): new more detailed XML description compared to the previous one, the DTD
