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
your radio when roaming from site to site. As
you roam throughout a PassPort System’s
coverage area, your HT1250•LS+ radio
regularly monitors 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 preprogrammed 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
Your HT1250•LS+ radio needs to register on
the PassPort system before communication
with your talkgroup can begin. 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:
