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 SRG3500.
Once switched to DMO Gateway mode, the SRG radio
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.

NO NETWORK COVERAGE
Direct Mode Repeater:
Extending Operational Reach
In situations where there is no network coverage available
the 10 watt DMO Repeater allows multiple Direct Mode
users to exchange voice and data messages over a wider
TMO
area with increased reliability. The DMO Repeater is ETSI
compliant Type 1A which uses a single frequency saving
scarce spectrum.
