Dynamic Group Number Assignment (Dgna) - Motorola MTP850 User Manual

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 your terminal to
add talkgroups or to update the existing talkgroups, or to
delete talkgroups from the list. This operation is performed by
transmitting the data into your MTP850.
Your Service Provider can gather some Talkgroups under one
Super-group and transmit it to your MTP850 as a DGNA. In
such a case, you will be able to participate in calls to/from all
the groups in the Super-group.

DGNA notification was configured by your
Service Provider, you will get a tone
