1.2.4 AVAILABLE MOUNTING OPTIONS
Front Mount - The operating controls are on the front on the radio, so the radio must be mounted
within reach of the user.
Remote Mount, Single Control Unit - The operating controls are located on a remote mounted
control unit. The radio does not have operating controls.
Remote Mount, Dual Controls - A remote control unit is connected to the front mount radio.
This allows control from the front panel and the remote control unit.
Remote Mount, Dual Remote Control Units - Two remote control units are connected to the
remote mount radio. This allows control from both remote control units.
1.2.5 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 approximately 256 (or the available memory space as described in the following information).
Channels
A channel selects a radio channel or talk group in a system as follows:
Conventional Analog Mode - A channel selects a specific radio channel, Call Guard
[Continuous Tone Coded Squelch System
(CTCSS)/Digital Coded Squelch (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.
Trunked Project 25 Mode - A channel selects a specific talk group ID and other parameters
unique to that talk group.
SMARTNET/SmartZone and Project 25 Trunked Operation - A channel selects a specific
talk group, announcement group, emergency group, and other parameters unique to that talk
group.
As previously described, a maximum of up to 256 channels can be programmed. Although it
is theoretically possible to program any combination of systems that produces up to 256 total
channels, the maximum number may be limited by the available memory. For example, since
more memory is required to program a SMARTNET system than a conventional system, the total
number of channels decreases as the number of SMARTNET systems increases. The
