General Information
1.1.4 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.
1.1.4.1 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 is
limited to 864 based on the option enabled. Channels may also be limited by available
memory space as described in the following information.
1.1.4.2 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
(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.
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.
A maximum of up to 864 channels can be programmed. Although it is theoretically
possible to program any combination of systems that produces up to 864 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
programming software displays a bar graph which shows the amount of available memory
space that is used by the current data.
1.1.4.3 Zones
A zone is a collection of up to 16 channels of any type. For example, a zone could include
12 conventional channels and 4 SMARTNET channels. One use of zones may be to
program the channels used for operation in a specific geographical area. Up to 54 zones
can be programmed depending on the option enabled.
