1 Scope
The present document applies to monitoring and control of Infrastructure Environment i.e. power, cooling and building
environment systems for telecommunication centres and access network locations.
Interoperability of heterogeneous management interfaces and systems with multi-vendor equipment is the key issue.
The present document gives a general approach from equipment to management system.
The multi-part deliverable is composed of a generic core part (part 1) and several specific parts for equipment category
(part 2 and following).
The core document defines:
• The site equipment map and its division in functional subsets e.g. DC system which introduces part 2 and
following.
• The generic set of exchanged information required at the interface of equipment, which is instanced for each
equipment subset in part 2 and following.
• The minimum requirement for network architecture allowing some compatibility with old existing interface
and the mechanism to exchange data between network element.
• The data interface protocol for remote or local site management (Machine to Machine Interface MMI) and
Human Machine Interface HMI for monitoring and controlling.
• Recommendations for sure management network such as dependability, data back-up, data coherence and
synchronization all along the management network, response time, fault detection and partial service in case of
failure.
2 References
References are either specific (identified by date of publication and/or edition number or version number) or
non-specific.
• For a specific reference, subsequent revisions do not apply.
• Non-specific reference may be made only to a complete document or a part thereof and only in the following
cases:
- if it is accepted that it will be possible to use all future changes of the referenced document for the
purposes of the referring document;
- for informative references.
Referenced documents which are not found to be publicly available in the expected location might be found at
http://docbox.etsi.org/Reference.
For online referenced documents, information sufficient to identify and locate the source shall be provided. Preferably,
the primary source of the referenced document should be cited, in order to ensure traceability. Furthermore, the
reference should, as far as possible, remain valid for the expected life of the document. The reference shall include the
method of access to the referenced document and the full network address, with the same punctuation and use of upper
case and lower case letters.
NOTE: While any hyperlinks included in this clause were valid at the time of publication ETSI cannot guarantee
their long term validity.
