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.
