Executive summary
The present document will describe the generic monitoring and control interface for infrastructure equipment. The
present document should follow a two-stage approach:
a) protocol-independent information modelling;
b) protocol-specific data modelling e.g. in YAML/JSON.
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; also the monitoring energy and
environmental parameters for Information Communication Technology (ICT) equipment in telecommunications sites or
datacenter or customer premises are considered.
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 (the present document) and several specific parts for
equipment category.
The present document defines:
• The site equipment maps and its division in functional subsets e.g. DC system which introduces part 2 and
following parts of this multi-part deliverable.
• The generic set of exchanged information required at the interface of equipment, which is instanced for each
equipment subset in part 2 and following parts of this multi-part deliverable.
• The minimum requirement for network architecture allowing some compatibility with old existing interface
and the mechanism to exchange data between network elements.
• 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 a 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.
• The Measurement accuracy of Power, Energy and Environmental parameters (PEE).
An architecture for monitoring Power, Energy and Environmental parameters (PEE) for data originated by different
types of site infrastructure equipment is defined.
Introduction
The present document was developed jointly by ETSI TC EE and ITU-T Study Group 5. It is published respectively by
ITU and ETSI as Recommendation ITU-T L.MCI Gen [i.33] and ETSI ES 202 336-1 (the present document), which are
technically equivalent.

3.1 Terms
For the purposes of the present document, the following terms apply:
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 can be understood by itself by an operator and have at least one severity qualification or
codification (colour, level, 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.)
client post: any device (laptop, PDA, console, etc.) connected to servers via the operation system networks to perform
maintenance or supervision operations
NOTE: It is independent of object class and object properties. The most common functions are GET and SET,
equivalent to monitor and cont

Executive summary
The present document will describe the generic monitoring and control interface for infrastructure equipment. The
present document should follow a two-stage approach:
a) protocol-independent information modelling;
b) protocol-specific data modelling e.g. in YAML/JSON.
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; also the monitoring energy and
environmental parameters for Information Communication Technology (ICT) equipment in telecommunications sites or
datacenter or customer premises are considered.
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 (the present document) and several specific parts for
equipment category.
The present document defines:
• The site equipment maps and its division in functional subsets e.g. DC system which introduces part 2 and
following parts of this multi-part deliverable.
• The generic set of exchanged information required at the interface of equipment, which is instanced for each
equipment subset in part 2 and following parts of this multi-part deliverable.
• The minimum requirement for network architecture allowing some compatibility with old existing interface
and the mechanism to exchange data between network elements.
• 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 a 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.
• The Measurement accuracy of Power, Energy and Environmental parameters (PEE).
An architecture for monitoring Power, Energy and Environmental parameters (PEE) for data originated by different
types of site infrastructure equipment is defined.
Introduction
The present document was developed jointly by ETSI TC EE and ITU-T Study Group 5. It is published respectively by
ITU and ETSI as Recommendation ITU-T L.MCI Gen [i.33] and ETSI ES 202 336-1 (the present document), which are
technically equivalent.
