NETWORK
NO NETWORK COVERAGE
DIRECT MODE GATEWAY
IMPROVED COVERAGE
Links radios operating in Direct Mode with the trunked radio network extending primary radio coverage into areas of unreliable coverage or network dead spots found inside buildings, deep inside tunnels or in remote rural locations.
INTELLIGENT COMMUNICATION
With Sepura Intelligent Call Conversion, the calling party only needs to call the TETRA identity of the SRG3900. Once switched to DMO Gateway mode, the SRG3900 automatically converts and relays
the incoming call or message to the Direct Mode users.
OPERATIONAL EFFECTIVENESS
Status messaging and SDS based messaging, 
including text and GPS location reports,
are
seamlessly
transferred between the network and Direct Mode users. In operational terms,
a control room dispatcher is able to track the positions of the individual users in a greater number of scenarios.
