About Zones
Figure 1-1 Zone Description
Zone data in a Conventional Group (Analog) or Conventional Group (NXDN) can be configured using KPG-169D/
KPG-170D/ KPG-175D/ KPG-175DN.
In addition, zone data for Site Roaming (NXDN) and Site Roaming with RAN (NXDN) can be configured as an NXDN
Conventional system zone. (Refer to 8.9 Site Roaming on page 76.)
Conventional Group (Analog)
A zone in an Analog Conventional system consists of Conventional channels that are used for communicating in
analog mode.
Conventional Group (NXDN)
A zone in an NXDN Conventional system consists of Conventional channels that are used for communicating in digital
mode using the NXDN protocol.
Site Roaming
This zone consists of channels in an NXDN Conventional system in which Site Roaming is enabled.
Site Roaming with RAN
This zone consists of channels in an NXDN Conventional system in which Site Roaming is enabled.
Two zone data can be configured for the transceiver. A maximum of 16 channels data per zone can be configured for the
transceiver. A maximum of 32 channels data can be configured for the transceiver in total.

About Communications Systems
FUNC (K)/Ver 1.20 INDEXCONTENTS xi
About Communications Systems
The transceiver can transmit and receive by using two communications systems, an Analog Conventional system and an
NXDN Conventional system.
In each system, the transceiver can communicate in analog mode or the NXDN digital mode.
To use the transceiver in each system of the Conventional Group, various parameters for a channel, such as transmit and
receive frequencies, and parameters for other various functions related to transmission and reception must be configured
for a zone in the Conventional Group by using KPG-169D/ KPG-170D/ KPG-175D/ KPG-175DN.
Analog Mode
Analog mode is the mode to transmit and receive an analog signal. This mode is available only in Narrow.
To communicate via a repeater in analog mode, a repeater supporting analog signals (an NXR/ TKR series repeater) is
required.
NXDN Digital Mode
NXDN digital mode is the mode to transmit and receive an NXDN digital signal. This mode is available only in Very
Narrow.
To communicate via a repeater in NXDN digital mode, a repeater supporting NXDN (an NXR series repeater) is
required.
