Gateway Mode
NOTICE: This feature is a selling feature.
NOTICE: Gateway 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 7: 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 gateway mode, individual and group calls cannot be initiated. Any active TMO scanning is also
suspended, including the scanning of supergroups.
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 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).
To prevent gateways from switching to background mode due to receiving a radio signal, your service
provider sets up a signal strength threshold. Any signal with strength lesser than the threshold is
ignored and the gateway continues to operate.
When in the background mode, the gateway constantly surveys the DMO channel to determine when it
is free. After 10 seconds of inactivity on the DMO channel, the gateway leaves the background mode.
Gateways roam between TMO sites. To prevent disconnecting an ongoing call due to roaming, the site
switch is delayed until it is no longer in range of the given site.
