内蔵モデムの適応規格 (規格/プロトコルなど原文

The ASUS Tablet 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 dierences between the individual
PSTNs provided in dierent 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 rst instance.
Overview
On 4th August 1998 the European Council Decision regarding the CTR 21
has been published in the Ocial 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 justied case service) in which network addressing, if provided,
is by means of dual tone multi-frequency signalling.
Network Compatibility Declaration
Statement to be made by the manufacturer to the Notied Body and
the vendor: “This declaration will indicate the networks with which the
equipment is designed to work and any notied networks with which the
equipment may have inter-working diculties.”
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 notied networks with which the equipment may have inter-
working diculties. 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 Notied Body of CETECOM issued several pan-European
approvals using CTR 21. The results are Europe’s rst modems which do
not require regulatory approvals in each individual European country.
