Personality; Mpt; Talkgroup; Fixed And Dynamic Groups - Motorola GP-688 Manual

PERSONALITY

The personalities described below are
programmed into your radio by your dealer and
are accessible either via the personality button
or via the menu.
A radio personality contains data such as
frequencies, display text, alert tones, permitted
calls etc. which determines the mode of
operation of your radio. Your radio may be
programmed with up to 4 different
personalities, selected from MPT, Talkgroup
and Conventional.

MPT

This personality permits the radio to operate in
a trunked mode. Incoming and outgoing calls
are set up using a defined set of rules or
protocol between your radio and a controller in
a similar manner to your home telephone. Your
radio 'registers' onto an MPT trunked system
as described in GETTING STARTED - Radio
Registration.

Talkgroup

Talkgroup is an MPT personality following the
same rules or protocol, but is primarily for
talkgroup calls. In talkgroup personality,
talkgroups are contained in a Talkgroup list,
similar to the Contact list, which is scrolled and
selected using the Rotary Knob (1).
On selection of a talkgroup, you may send and
receive calls as described below.

Fixed and Dynamic Groups

These groups form part of the Talkgroup
Personality, such that when this personality is
selected your talkgroup list shows only these
groups.
A fixed group is a group of users, the address
(number / alias) of which is preprogrammed
into your radio by your dealer.
A dynamic group is a group of users, the
address (number) of which is sent to your radio
'over air' at any time via the system controller.
Therefore at any time you may become a
member of a dynamic group, able to receive
calls and (depending on how your radio is
programmed) send calls to that group.
