2N - VoiceBlue Lite
3.1. Proper Installation Conditions
The following installation conditions must be met for a proper
function of VoiceBlue Lite:
• Sufficient space for VoiceBlue Lite installation.
• Sufficiently strong signal from the GSM network with which
VoiceBlue Lite shall work with (the minimum signal intensity
value is –80dBm). To measure the signal intensity before
VoiceBlue Lite installation you can use a mobile telephone
with the Net monitor function enabled (e.g. SIEMENS,
NOKIA).
• A corresponding capacity of the GSM network (no GSM cell
overloading). Remember that the use of multiple GSM
gateways in one location may overload your current GSM cell
base. This might lead to a permanent or occasional rejection of
calls to GSM networks!
• No strong electromagnetic radiation on the installation site.
• No strong reflections on VoiceBlue Lite antenna sites.
• A correct VoIP connection configuration according to SIP
and other VoIP recommendations.
3.2. VoiceBlue Lite Installation
• Place the VoiceBlue Lite GSM gateway to an environment that
meets the gateway working conditions.
• It is recommended to connect the supply adapter with a battery
backup (UPS) and appropriate surge protection.
• Configure the GSM gateway using the VoiceBlue Lite software
available on the product CD enclosed.
• You may use remote GSM gateway administration through the
Ethernet for a comfortable GSM gateway management.
