3.3.1 Noise Reduction
Active noise reduction uses advanced signal processing algorithms
in the IP stations. These algorithms will try to identify the noise signal
(background repetitive audio). When noise is identified, the algorithm
filters out the noise while retaining the voice signal. If you set noise
reduction at a high level, more of the voice signal will also be filtered out.
The range of filtering levels are from 0 to 7 for the station characteristics
to be tuned optimally to the environment. The settings will take effect
immediately after being saved, making it easy to test various parameters
while the conversation is active.
Noise Reduction Level
is configured in the web server of the IP station.
● Select

from the menu
Noise Reduction Levels
● Level 0 means that noise reduction is disabled
● Level 1 gives a maximum noise reduction of 0.2 dB
● Level 2 gives a maximum noise reduction of 6.2 dB
● Level 3 gives a maximum noise reduction of 12.2 dB
● Level 4 gives a maximum noise reduction of 18.3 dB
● Level 5 gives a maximum noise reduction of 24.3 dB
● Level 6 gives a maximum noise reduction of 30.3 dB
● Level 7 gives a maximum noise reduction of 36.3 dB
By default, the noise reduction level is disabled, i.e. set to 0. In very noisy
environments, we recommend setting the noise reduction level to 4. At
this level, the audio quality is good when quiet, and when noisy, most of
the noise is filtered out.

VLAN
VLAN Tagging or IEEE 802.1Q is a networking standard allowing multiple
bridged networks to transparently share the same physical network
link without leakage of information between networks. IEEE 802.1Q —
along with its shortened form
dot1q
— is commonly used to refer to the
encapsulation protocol used to implement this mechanism over Ethernet
networks.
"
STENTOFON IP Stations support 802.1Q as from firmware version 01.09.3.0.
