A-deviations

A-deviation: National deviation due to regulations, the alteration of which is for the time being outside
the competence of the CENELEC national member.

This European Standard does not fall under any Directive of the EC.

In the relevant CENELEC countries these A-deviations are valid instead of the provisions of the
European Standard until they have been removed.

Clause Deviation
3.1.58 Norway
According to Regulations on Electronic Communications Networks and Services (Ecom
Regulations) laid down by the Norwegian Ministry of Transport and Communications on 16
February 2004, the following applies:

When installing coaxial cable-based networks, the part of the network to which the end-user
is connected shall be placed in a star structure. It is not permitted to insert receiver
connections into the connection between the star points.

(Dutch Technical Regulations for CATV networks (Technische Voorschriften voor Centrale
Antenne Inrichtingen, 3e uitgave), 21 December 1977, which are valid for CATV networks in
accordance with Article 21 of the Dutch Telecommunications law (Stb. 1988, 520))

Replace by/add the following “minimum and maximum carrier levels” regulation as indicated
in Table ZB.1.
Table ZB.1 – Carrier signal levels at any system outlet
FM sound mono: 80 dB(µV)
