Automatic Gain Control Settings (AGC)/Expander
The correct functioning of the AGC can be optimised via several parameters.
• Threshold: The AGC does not start before the signal exceeds the threshold
value set here. The default setting is -45 dBFs.
• Level: The level set here corresponds to the average desired level. Please
consider sufficient head room. The default setting is -24 dBFs.
• Speed: Depending on the desired speed of the level adjustment (Slow,
Medium or Fast) you can adjust the setting of the AGC speed. The faster
the AGC must work the more noticeable are the inconsistencies. If the se-
lected speed is too slow, the caller signal is too low or too loud on average.
The default setting is Medium.
• With the use of the key Default Settings the default settings named above
can be configured and the Expander can be activated.
Volume Control
Under Volume Control you can select the Default Value for the volume con-
trol within the range of -16 ... +16 dB.
5.5.2.1.4 Database
b-line XT can work with a caller database where you can save telephone num-
bers and caller information. If a telephone number is stored in the database,
the caller information such as e.g. the caller’s name will be immediately dis-
played when a call is coming in and the number is transmitted.
