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).
Note: This is a selling feature.
