Internal Modem Compliancy
The Notebook PC with internal modem model complies with JATE (Japan), FCC (US, Canada,
Korea, Taiwan), and CTR21. The internal modem has been approved in accordance with Council
Decision 98/482/EC for pan-European single terminal connection to the public switched
telephone network (PSTN). However due to differences between the individual PSTNs provided
in different countries, the approval does not, of itself, give an unconditional assurance of
successful operation on every PSTN network termination point. In the event of problems you
should contact your equipment supplier in the first instance.
Overview
On 4th August 1998 the European Council Decision regarding the CTR 21 has been published
in the Official Journal of the EC. The CTR 21 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 21 (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"
Network Compatibility Declaration
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
21. 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.
