This European Standard was approved by CENELEC on 2006-04-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, the Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia,
Spain, Sweden, Switzerland and the United Kingdom.

Foreword
This European Standard was prepared by CENELEC Technical Committee TC 209, "Cable networks for
television signals, sound signals and interactive services" on the basis of EN 50083-2:2001, its
amendment A1:2005 and a further amendment to EN 50083-2, resulting from two draft amendments
(prA2 and prAA) that were submitted to the Unique Acceptance Procedure and approved by CENELEC on
2006-04-01 to be published as part of a new edition of EN 50083-2.

The following dates were fixed:

– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2007-04-01

– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2009-04-01
