ASUS Tablet and ASUS Keyboard Dock E-Manual

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 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.

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 multi-frequency signalling.

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.”

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.
