TMO Group Call
Dynamic Group Number Assignment (DGNA)
DGNA provides the ability for a network operator or
authorised user to dynamically allocate new, or update
existing talkgroups to selected terminals over the air
interface. Using supplementary services messages (SS-
DGNA), the network operator can command the terminal to
add talkgroups to the existing talkgroups list, or to delete
talkgroups from the list. This operation is performed by
transmitting the data into your MTM800.
DGNA Reception with Notification Message
When a DGNA is received and DGNA
notification was configured by your Service
Provider, you will get a tone indication and
notification message (“Programming
Entries...”), and then a display of the new assignments.
If DGNA notification was not configured by your Service
Provider, you will only get a tone indication and only if a
selected group was changed by the DGNA.
1. To view the added/deleted talkgroups
details press
View. You may scroll
through the list using the
keys.
2. To return to the initial Mode display press
Back.
3. To select the DGNA group, press Select. Or scroll to
another group using the navigation key, and press
Select.
If configured, a newly added group will also become the
newly selected talkgroup.
Your Service Provider can gather some Talkgroups under one
Super-group and transmit it to your MTM800 as a DGNA. In
such a case, you will be able to participate in calls to/from all
the groups in the Super-group.
Once you exit the DGNA notification screen, the Select key
disappears. To select one of the newly added groups, see
page 30.
