1.1 Features
The following are some of the features of the TB9100 base station:
■
Fully compliant with the Project 25 Common Air Interface. Can
therefore interoperate with any similarly compliant radios.
■
Dual mode. Comprehensive analog and digital features ensure
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. 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.
■
An integrated wiring solution is provided for the system control bus and
DC power connections to each reciter.
■
Reciters can be replaced without affecting the operation of other reciters
in the same subrack.
■
Rugged construction with generous heatsinks and fan-forced cooling for
continuous operation from –30°C to +60°C (–22°F to +140°F).
The following are some of the features of the P25 Console Gateway:
■
Project 25 standard DES or AES encryption and decryption at the analog
line interface.
■
Support for MDC1200, E & M, and function tone signaling on the
analog line.
1.2 Base Station and Console Gateway
Like the base station, the P25 Console Gateway can be unpacked, given an
IP address, set up on the bench, and used with a CTU. AC and DC power,
the analog line, and Ethernet are connected up in the same way. The console
gateway has a front panel with fans and a control panel. It can also be
monitored and configured by the CSS, much as a TB9100 base station.
Although the gateway has an RF board (as well as a digital board and a
network board), that board has no function. The P25 Console Gateway
subrack can be populated with multiple gateway modules, in the same way
that the base station can be populated with multiple reciters. Faulty gateway
modules or PMUs are replaced in the same way.
The control panel operates as for a base station, except that the Carrier
button has no effect and the microphone can only transmit via the
connected channel group. The speaker can output the channel group’s vote
winner (if unencrypted), but the Console Gateway cannot itself provide any
receive audio.
