INTRODUCTION
INTRODUCTION
Welcome to Motorola’s
CDM Series family of
radio users. The
CDM1550•LS
+
, the
Intelligent Radio,
combines the very latest
in two-way technology
while delivering
outstanding functionality at the touch of a
button.
The CDM1550•LS
+
mobile radio operates on
PassPort and LTR trunked and conventional
radio systems.
TRUNKED RADIO SYSTEMS
Trunked systems allow a large number of users
to share a relatively small number of
frequencies or repeaters without interfering
with each other. The airtime of all the repeaters
in a trunked system is pooled, which
maximizes the amount of airtime available to
any one radio and minimizes channel
congestion.
PassPort
™
Trunked Systems
PassPort is an enhanced trunking protocol
developed by Trident Micro Systems that
supports wide area dispatch networking. A
network is formed by linking several trunked
sites together to form a single system. This
offers users an extended communication
coverage area. Additionally, users with
PassPort can seamlessly roam among all sites
within the network. Seamless roaming means
that the radio user does not have to manually
change the zones on the radio when roaming
from site-to-site.
LTR
™
Trunked Systems
LTR is a transmission based trunking protocol
developed by the E. F. Johnson Company for
primarily single site trunking applications. In
transmission trunking, a repeater is used for
only the duration of a single transmission.
Once a transmission is completed, that
repeater becomes available to other users.
This means that a conversation comprised of
many transmissions may occur over several
different channels within the LTR system. This
method of trunking provides system efficiency
