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.

1 National requirements will apply only if the equipment may use
pulse dialling (manufacturers may state in the user guide that the
equipment is only intended to support DTMF signalling, which
would make any additional testing superfluous).

In The Netherlands additional testing is required for series
connection and caller ID facilities.
