Introduction

This Technical Report has been prepared to support the harmonization of terminology used by

Technical Committees of CENELEC and ETSI, who are working in the field of Broadband Deployment,

to ensure that their deliverables use consistent terms and definitions. It will allow Technical

Committees to revise their existing publications to align the partly diverging terminology, which can

currently be found in some of those publications.

Technical Committees will benefit from a harmonized glossary of terms and definitions during the

development of future documents, in particular for cross-over topics affecting several Technical

Committees in CENELEC and/or ETSI. Furthermore, readers of those documents will appreciate an

advanced understanding of different deliverables addressing the same field of technology, as

discussions about the meaning of terms will be minimized.
