In order to access a SmarTrunk II site, the subscriber
must be programmed as a valid user by the system
operator of the site. Channel Banks may also be used to
access conventional channels. When a subscriber
selects a Channel Bank programmed with conventional
channels, the radio automatically enters into the
conventional mode.
This feature is useful in cases with the system operator allows
talk-around operation among the user’s radio. Talk-around
can be used for short range direct radio-to-radio
communications without going through the trunking system.
Multiple PTT Groups
The Multiple PTT Groups feature allows subscribers to call different
groups of subscribers simply by pressing the PTT (Push-To-Talk)
button. Previously, a subscriber could call only one group by pressing
PTT.
The system operator may program up to 16 Group Codes in the radio
logic board which may be selected by the subscriber by using one of
the spare function switches on the radio which becomes the group
switch when the radio is programmed for SmarTrunk operation. The
subscriber selects the desired group with the Group Switch. When the
subscriber presses PTT, the selected group is called. In addition, the
radio will receive calls placed to the selected group.
This feature enables subscribers who are not equipped with a DTMF
keypad to call different groups. In addition, this feature allows
subscribers to join
different PTT groups
on different days. For
example, changing
PTT groups is useful
in applications where
a subscriber regularly
changes project
groups or where a
mobile radio is
frequently used by
employees who are in
different groups.
