Overview
On th August 18 the European Council Decision regarding the CTR 1 has
been published in the Official Journal of the EC. The CTR 1 applies to all non
voice terminal equipment with DTMF-dialling which is intended to be connected
to the analogue PSTN (Public Switched Telephone Network).
CTR 1 (Common Technical Regulation) for the attachment requirements for
connection to the analogue public switched telephone networks of terminal
equipment (excluding terminal equipment supporting the voice telephony
justified case service) in which network addressing, if provided, is by means of
dual tone multifrequency signalling.
Network Compatibility Declaration
Statement to be made by the manufacturer to the Notified Body and the vendor:
"This declaration will indicate the networks with which the equipment is designed
to work and any notified networks with which the equipment may have inter-
working difficulties. "
Statement to be made by the manufacturer to the user: "This declaration will
indicate the networks with which the equipment is designed to work and any
notified networks with which the equipment may have inter-working difficulties.
The manufacturer shall also associate a statement to make it clear where network
compatibility is dependent on physical and software switch settings. It will also
advise the user to contact the vendor if it is desired to use the equipment on
another network. "
Up to now the Notified Body of CETECOM issued several pan-European approvals
using CTR 1. The results are Europe's first modems which do not require
regulatory approvals in each individual European country.
Non-Voice Equipment
Answering machines and loud-speaking telephones can be eligible as well as
modems, fax machines, auto-dialers and alarm systems. Equipment in which the
end-to-end quality of speech is controlled by regulations (e.g. handset telephones
and in some countries also cordless telephones) is excluded.
