DMO Group Call

General

In DMO, the MTP850 can be used without your Service
Provider's infrastructure.
Direct Mode allows communication with other terminals also
operating in Direct Mode, which are on the same frequency
and talkgroup as your MTP850.
In DMO it is only possible to place Group Calls, Emergency
Group Calls and Private Simplex Calls.
You can receive a call:
• From the selected talkgroup
• From other users within talkback range (if configured by
your Service Provider). This is called an InterMNI (Mobile
Network identity) call.
• From an open group. (An open group is a super-group to
which all DMO groups belong.)
When you start a call, the members of the selected talkgroup
who have their units turned on, and are within the group
subscriber identity (as configured by the Service Provider),
will receive the transmission.
In DMO the MTP850 can communicate with the trunking
system (and vice-versa) if the Gateway option is enabled in
the MTP850.
To enhance the terminal's DMO coverage area the DMO
group can link to a repeater if the Repeater option is enabled
in the terminal. Additionally the GW + Rep (gateway and
repeater) communication mode can be used.
If Transmit Inhibit is activated while the terminal is set to
DMO, the PTT is disabled. You can only listen. For detailed
information on Transmit Inhibit, see page 51. DMO Talkgroup
selection is allowed when Transmit Inhibit is activated.
