GENERAL OPERATION
18
When a SMARTNET or SmartZone channel is
selected or the radio is powered up on one of those
channels, it searches for a control channel. Once a
control channel is found, the alias (name) of the
selected channel is displayed and the radio attempts to
register on the radio system. If a control channel could
not be found (because of an out of range condition or
the system ID is not correct, for example), “NO SYS”
(early units) or “Out Rnge” (later units) is displayed
and the radio continues to search for a control channel.
The control channel transmits and receives
system information to and from all radios registered on
the system. Therefore, once a control channel is found,
it is continuously monitored for incoming call infor-
mation and is used to make call requests. The radio
automatically changes to a traffic channel to place and
receive calls and then returns to the control channel
when the call is complete. Operating features unique
to SMARTNET/SmartZone channels are described in
Section 6.
3.9.4 P25 TRUNKED MODE
The P25 Trunked operating features are very
similar to the SmartZone type just described. Since
SmartZone features are also similar to SMARTNET
features, all three modes are described in the
Section 6. Some differences between the P25 Trunking
and SmartZone modes are as follows:
• Digital signaling is always used with P25 calls.
Either analog or digital signaling may be used for
SmartZone calls.
• Calls made to a specific radio in the P25 mode are
called Unit Calls. In the SMARTNET/SmartZone
mode they are called Private Calls.
• Messaging is not available with P25 calls.
• The P25 control channel data rate is 9600 baud and
the digital voice data rate is also 9600 baud. With
SmartZone operation, the control channel data rate
is 3600 baud (both digital and analog calls) and the
narrowband digital voice data rate is 9600 baud.
• The P25 mode uses a system ID, Wide Area
Communications Network (WACN) ID, and RF
Subsystem ID (RFSS). The SmartZone mode does
not use the WACN and RFSS IDs.
• P25 Unit IDs can be 1-16,777,215 (000001-FFFFFF
hex) and SmartZone Unit IDs can be 1-65,535
(0001-FFFF hex).
3.9.5 SYSTEMS, CHANNELS, AND ZONES
A zone and channel are selected to place and
receive calls. The following describes the relationship
between systems, channels, and zones.
Systems
A system is a collection of channels or talk
groups belonging to the same repeater site. It defines
all the parameters and protocol information required to
access a site. Up to 16 systems of any type can be
programmed.
The maximum number of channels assignable to
a system is limited to 512. Channels may also be
limited by available memory space as described in the
following information.
Channels
A channel selects a radio (RF) channel or talk
group as follows:
Conventional Analog Mode - A channel selects a
specific radio channel, Call Guard (CTCSS/DCS)
squelch coding, and other parameters unique to that
channel.
Conventional Project 25 Mode - A channel selects a
specific radio channel, NAC squelch coding, talk
group ID, and other parameters unique to that channel.
SMARTNET/SmartZone and Trunked Project 25
Modes - A channel selects a specific talk group,
announcement group, emergency group, and other
parameters unique to that talk group.
A maximum of up to 512 channels can be
programmed with the preceding modes. These chan-
nels can belong to a single system or multiple systems.
