Talking Party Identification (TPI)

This feature enables the identity of the calling terminal to be displayed on the called terminals.
Benefits:
The user always knows who's talking before answering the call - this enables preparation or
decision to accept or reject the call
2.2.3

Call Restoration

Dependent on available traffic channels, this feature enables a terminal to rejoin a group call as it
moves from one cell coverage area into another cell coverage area, this operation is seamless.
2.2.4

Announcement Talk Group (ATG - also called Multi Group)

This is a special type of group that is logically a group in its own right, but also may contain
subgroups. When selected, the terminal monitors the traffic received for the Announcement Group
and subgroups, but if a subgroup has been selected, the terminal will monitor traffic received for the
announcement group as well as the traffic received for any of the associated subgroups.
The terminal does not monitor the active scan list groups when an announcement group is selected.
When the user selects one of the subgroups of the announcement group, the traffic for the subgroup
is monitored as well as the traffic for its announcement group (but not other subgroups).
The terminal can be programmed to prevent user call initiation or talk back on announcement talk
groups.
This is a Motorola Dimetra ONLY feature (not in Standard or TIP)
