Encrypted voice quality is indistinguishable from unencrypted.
The trunked analog gateway supports Project 25 compliant DES (via the
basic encryption license) and AES (Advanced Encryption Standard) with the
AES license.
The control panel in a trunked analog gateway has limited functionality.
The Power and Alarm LEDs are operational, but the microphone and
speaker are not used.
1.6 Applications
TB9100 base stations can be used as repeaters or as base stations. They can
be connected together as a channel group, to form a wide area repeater or
wide area base station. They can be used in trunking systems and in
conventional systems with analog or digital dispatch equipment. For more
information, see the appropriate Tait P25 System Manual.
Repeater
The base station can function as a standalone repeater. The analog line is not
used and the Ethernet line is only used for CSS access.
Line-Connected Base Station
Analog The base station can function as a line-connected base station. Analog
dispatch equipment is connected to the analog line.
Digital The base station can make available a digital fixed station interface (DFSI)
for connecting to digital dispatch equipment.
Channel Group
Base stations that are interconnected over an IP-based linking infrastructure
can be configured as a channel group. Together, they operate as a single
logical channel, forming a wide area repeater, wide area base station, wide
area trunking control channel or trunking traffic channel.
Trunking Control or Traffic Channel
Base stations can be interfaced to an external trunking site controller. Under
instructions from the site controller, they can function as a control channel
or a traffic channel.
