interoperability with analog or digital technology. The TB9100 can
switch seamlessly between analog FM and digital P25 communications
on a per-call basis.
■
Integrated built-in voting facility. In a TaitNet P25 network, TB9100
base stations use distributed voting to compare the received signals,
selecting the best quality signal for transmission through the system. No
external voter is needed.
■
Can be completely managed remotely from a PC running the Tait
Customer Service Software: configuration, alarm monitoring, fault
diagnosis, feature and firmware upgrades.

Rugged construction with generous heatsinks and fan-forced cooling for
continuous operation from –30°C to +60°C (–22°F to +140°F).
1.2 Modules
The TB9100 base station consists of several modules in a subrack: a power
management unit (PMU) to supply and manage power to the subrack, a
reciter (receiver and exciter), a power amplifier (PA), a front panel with fans,
and a control panel. The modules are interconnected at the front of the
subrack. External connections to the modules are located at the rear.
Modules come in different variants depending for example on the RF band
or the supply voltage. Many of them are common to the TB8100.
Applications such as a receive-only base station do not need them all.
Each module is inserted into the TB9100 4U subrack from the front and is
secured at the front with a metal clamp. Both clamp and module are easily
removed for rapid module replacement. The modules are secured laterally
with plastic guides that clip into the top and bottom of the subrack. These
guides can be easily repositioned to change the configuration of a subrack.
The heavier modules are also secured laterally by metal tabs at the rear of the
subrack.
The following provides a brief description of the available modules.
