PASSPORT TRUNKING
PassPort
®
is an enhanced, wide-area trunking
protocol developed by Trident Micro Systems.
Up to 128 trunked sites can be linked together
to form one PassPort system, which means
that your communications can extend far
beyond the reach of a single trunked site.
SEAMLESS ROAMING
PassPort Trunking systems offer you the ability
to seamlessly roam among all sites in a
network. Seamless Roaming means that you
do not have to manually change the zones on
the radio when roaming from site-to-site. As
you roam throughout a PassPort System’s
coverage area, your HT1250•LS+ radio is
regularly monitoring the RSSI (Received
Signal Strength Indication) level of the site on
which you are currently registered. In addition,
if the signal strength falls below the acceptable
threshold pre-programmed by your dealer,
your radio starts monitoring the RSSI level of
adjacent sites within the network. This allows
the HT1250•LS+ radio to quickly roam to the
site with the strongest signal, which provides
you with optimal audio quality throughout your
communications.
Initial Registration
Before communications with your talkgroup
can begin, your radio needs to register on the
PassPort system. Registration automatically
takes place upon radio power up or after
selecting the desired PassPort zone on the
selector knob unless your radio is Site
Restricted from that site or Group Restricted
from that talkgroup. What you see:
1 Upon radio Power
up, you see:
(if you select a
PassPort zone after
the radio is powered
up, see step 2).
2 The selected
PassPort Zone
Alias appears on the
display (if prepro-
grammed).
