Title
Characteristics of transport equipment – Description methodology and generic functionality
International Telecommunication Union/ITU Telcommunication Sector
Publication Date:
Jan 1, 2009
Scope:
This Recommendation specifies a methodology to describe
equipment for transport networks based on the transport processing
functions and architectural entities defined in [ITU-T G.805]. It
defines the set of generic atomic and compound functions and the
set of rules for how to combine them. The detailed characteristics
of equipment functional blocks of specific transport networks
(e.g., SDH, OTN) will be defined in follow-up Recommendations based
on this methodology. Equipment can then be described by an
equipment functional specification (EFS) which lists the atomic
functions and their interconnection.
In addition, generic functionality, processes and overall
performance objectives for transport networks are defined in this
Recommendation.
The internal structure of the implementation of this
functionality (equipment design) need not be identical to the
structure of the functional model, as long as all the details of
the externally observable behaviour comply with the EFS.
Equipment which is normally stated to be compliant with this
Recommendation may not fulfil all the requirements in the case that
it is interworking with old equipment that is not compliant with
this Recommendation.
