Caution
 Resetting factory values results in a change of the 2N ® VoiceBlue Next
Ethernet interface configuration!
 Using a defective Ethernet cable may lead to a high packet loss rate in the
Ethernet network and subsequent instability and poor quality of all
GSM/UMTS calls!
Antenna Splitter
The antenna splitter is a passive component that combines multiple GSM/UMTS
channels into one antenna. In 2N
® VoiceBlue Next, it combines two/four antennae into
one. The antenna splitter is placed in the installation box. It is a passive element – it
has a characteristic signal attenuation value that the antenna connected must
compensate. No antenna splitter is used for one-channel 2N
® VoiceBlue Next
gateways.
