7signal Sapphire Deployment Guide Release 3.1
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 observerd: the target wireless network may be configured to have MAC address
preventions so the MAC address of WLAN interface of the Eye unit must be white-listed as a
network client. Eye does not act as an access point of the wireless network.
MOS test connections
MOS test is a license-controlled feature and not used in every environment. MOS test requires
additional ports to be used. MOS traffic is special-purpose traffic with identical fingerprint than
any VoWLAN call would have.
Sonar may serve numerous Eyes concurrently and therefore it is able to listen numerous UDP
ports for incoming VoIP calls. Ports are listened in per-need basis. One UDP port may serve one
Eye at a time so the number of concurrent MOS tests in single Sonar is dictated by the number
of available ports that is configured during Sonar deployment phase.
Eye has one open UDP port for VoIP calls as it communicates with single Sonar only at a time.

In this case the Eye acts as a server and Carat software is a client. Carat does not make any SSH
connections, SSH is optional connection for operators.
