These products have further been assessed against the CTR21 
“deltas” which ensure maximum compatibility with the PSTN 
networks of the EU. These deltas are collectively referred to as the 
ATAAB Advisory Notes. ATAAB is the EU committee with 
representation from all member states and is responsible for 
maintaining CTR21 and the additional tests called up within the 
advisory Notes (or deltas). Compliance with these Advisory Notes 
ensures correct interworking of the terminal equipment (modem) 
and the network. 
Network Compatibility Declaration
Where indicated by the EU permission to connect symbol, this 
equipment is suitable for use on all PSTN networks within the 
EU. In order to maintain correct operation when interworking 
with the PSTN network, some restrictions to specific settings are 
advised. These are detailed below: 
For PSTN Operation in Portugal
1.) Terminal equipment must answer an incoming call 
within two minutes from the start of the ringing signal, 
otherwise the exchange may stop providing Ring 
indication (ensures compliance with ATAAB note 
AN011).
The answer on ring count option (S0) should not be set to a 
value greater than 20 (factory default =0). 
For PSTN Operation in All EU countries
1.) When dialing without dial tone detection, the network 
cannot guarantee acceptance of the dialing signal if 
these signals occur earlier than 3s or later than 5s after 
seizing the line (ensures compliance with ATAAB note 
AN01).
The Blind Dial Pause or Dial Wait option (S6) should be set 
between 3 and 5s. (factory default =4). 
All other ATAAB Notes are automatically catered for by the 
modem.
