(規格/プロトコルなど原文掲載)

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.
