Gateway Mode
NOTICE: Repeater Mode does not apply to MTM5200 radio.
The Gateway Mode allows your radio to work as a gateway and thus provide connectivity among
radios operating in DMO and TMO Modes.
Figure 4: Gateway Mode Operation

TMO
A DMO/TMO gateway is used to provide gateway connectivity between radio operation in the DMO
and the TETRA TMO network. In other words, the gateway mode provides the interface between
TETRA DMO and TMO modes.
While in the gateway mode, any individual call from both DMO and TMO cannot be answered. If the
call is incoming from TMO, it is rejected with disconnect cause as the called party is busy. The missed
call is added to the missed call list. If the call is incoming from DMO, it is ignored.
While in the gateway mode, group calls are supported. When the gateway receives a group call
addressed to its current selected TMO talkgroup, it forwards the call on to the respective mapped DMO
talkgroup. If the DMO channel is not free, and the incoming call has Emergency priority, then
preemption request is sent.
When the gateway receives a group call addressed to its current selected DMO talkgroup, it forwards
the call on to the respective mapped TMO talkgroup. The DMO radio that initiated the call requires
correct setup for gateway calls (otherwise the call is rejected).
