Overview

kSIST prES 202 336-5 V1.1.1:2010 addresses the monitoring and control interface for infrastructure equipment in telecommunication networks, with a specific focus on AC diesel back-up generator systems. Developed by SIST (Slovenian Institute for Standardization) and based on ETSI ES 202 336-5, this part of the Environmental Engineering (EE) series provides the data description, XML structures, and information models necessary for AC diesel generator system control, supporting the reliability and fault-tolerance requirements of modern telecommunication installations.

The standard ensures consistent interfaces and data formats for monitoring power, cooling, and building environment systems, contributing to the seamless integration and management of telecommunication infrastructure.

Key Topics

• AC Diesel Generator System Monitoring
  Provides definitions for monitored and controlled generator architectures within telecom sites, specifically covering AC diesel back-up units.

• Essential Data and Information Model
  Specifies the minimum set of information (e.g., alarms, status, measurements) required at the interface, as well as the corresponding XML and DTD structures for data exchange.

• XML-based Data Structures
  Standardizes the representation of generator system components, such as engine, alternator, fuel system, cooling circuits, and control units, using XML to facilitate interoperability and automated data collection.

• Mandatory and Optional Monitoring Functions
  Outlines both mandatory supervision parameters (alarms, fuel levels, voltage, status) and optional/non-mandatory monitoring (maintenance records, performance statistics, test results).

• Integration with Site-Wide Management Systems
  Affirms that generator monitoring data can be integrated into larger site-wide energy management architectures, with compatibility assured by referencing the core generic interface standard (Part 1).

Applications

This standard is essential for:

• Telecommunication Network Operators
  Ensuring the reliable operation of AC diesel back-up generators within network nodes, data centers, and exchange sites, especially during power disruptions.

• Infrastructure Equipment Manufacturers
  Designing generator monitoring and control units (XCU) and data gathering units (DGU) to conform with standardized information models, ensuring compatibility and ease of maintenance.

• Systems Integrators and Maintenance Providers
  Implementing unified monitoring solutions capable of automated alarm management, data logging, and remote diagnostics for critical power infrastructure in telecommunications.

• Facility Managers in Critical Infrastructure
  Using standardized monitoring and test procedures to automate preventive maintenance and streamline compliance with safety and operational regulations.

Practical benefits include:

• Improved fault detection and event notification through uniform alarm structures and status monitoring.
• Enhanced reliability by supporting preventative maintenance scheduling and running tests.
• Streamlined integration of site-wide energy management using standardized XML interfaces.
• Facilitation of remote monitoring, diagnostics, and control operations through interoperable management applications.

4 Back-up generator system control and monitoring
presentation
Some telecom or datacom site (datacenters) are powered by the public AC mains and are often backed-up by one or
several generators when the mains voltage is either interrupted or out of predefined ranges of voltage, frequency or
distortion.
The starting order may also come from the permanent power subsystem when a persistent battery discharge is observed.
The back-up generator described in ES 202 036-1 [1] is generally of diesel

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
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 [5].
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 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 [6]). documents.XML is designed to describe data and focus on what data is. XML must
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 Back-up generator system control and monitoring
presentation
Some telecom or datacom site (datacenters) are powered by the public AC mains and are often backed-up by one or
several generators when the mains voltage is either interrupted or out of predefined ranges of voltage, frequency or
distortion.
The starting order may also come from the permanent power subsystem when a persistent battery discharge is observed.
The back-up generator described in ES 202 036-1 [1] is generally of diesel type and with AC interface output as
