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.
