Deployment Guide
understanding of the network between the endpoints and the ability to affect all the network
elements necessary.
To test and use the wireless connection the following variables must be known:
● ESSID – test parameter to connect to a particular wireless network.
● WLAN encryption
Network keys – pre-shared keys, certificates or similar - are stored in Eye file system by Carat application.
To be observed: the target wireless network may be configured with MAC address restrictions so the MAC
address of WLAN interface of the Eye unit must be white-listed as a network client. The Eye does not act
as an access point of the wireless network. The Eyes WLAN MAC address can be discovered using the
Configurator or via SSH and executing a ifconfig –a.
MOS test connections
MOS test requires additional ports to be used. The MOS traffic test uses special-purpose traffic with an
identical fingerprint to a VoWLAN call.
The Sonar may serve numerous Eyes concurrently and therefore it is able to listen to numerous UDP ports
for incoming VoIP calls. Ports are listened on a per-need basis. One UDP port may serve one Eye at a
time so the number of concurrent MOS tests on a single Sonar is dictated by the number of available ports
that are configured during the Sonar deployment phase.
The Eye has only one UDP port open for VoIP calls as it communicates with a single Sonar at a time.
