Note: Auto-tuning should be repeated if any changes are made later to the physical FXO line
connections or tuning parameters. Auto-tuning must also be repeated when the country is changed.

To adjust audio manualy:
4 In the "Line Dynamic Range (Boost)" field, specify the audio boost level on these FXO lines. When
transmit dynamic range is configured, the receive range is automatically balanced accordingly, so
that the overall gain from the FXO network to pulse code modulation (PCM) remains within the
normal target value for the appropriate country. Valid settings are:
• Standard (-3dB)
• Full (0dB)
• Extended (+3dB)
5 The "Line Interface" and "Line Profile" parameters are read-only fields. These fields are updated by
the Auto-Tuning Wizard if required. These line tuning parameters balance the line hybrid on the
AastraLink's FXO interfaces so that it matches the characteristic line impedance.
6 In the "Echo Cancel" field, echo cancellation is disabled by default. This parameter allows you to
enable echo cancellation for the FXO lines. Enable this parameter by checking the box.
