equipment. This option is effectively the same as the receive-only base
station; in addition, the receiver is disabled.
Encryption
The TB9100 supports end-to-end encryption between radios. The repeated
voice quality is indistinguishable from non-encrypted voice. If the control
panel speaker is turned on, it plays continuous noise throughout the
transmission (silence into the transmitting radio sounds the same as voice),
unless the base station has a basic encryption license, in which case
encrypted calls cannot be heard at all through the front panel speaker.
Support is also available for encryption and decryption at the base station
analog line interface or at an analog gateway. An additional AES encryption
license is available in addition to the basic (DES) encryption license.
1.6 Base Station Applications
TB9100 base stations can be used as repeaters, as base stations, and they can
be connected together to form a wide-area repeater or wide-area base
station. For more information, see the white paper
TaitNet P25 Networks .
Repeater
TheTB9100 base station can function as a standalone repeater. The analog
line is not used and the digital line is only used for CSS access. Software
licenses for these lines are not needed.
Line-Connected Base Station
A TB9100 base station can function as a line-connected base station. A
dispatch console is connected to the analog line. If the repeat function is
enabled, the base station repeats what it receives unless the microphone or
analog line input is being used. If the repeat function is disabled, the base
station puts the received signal on the analog line but does not transmit it. A
software license for the analog line is needed.
TaitNet P25 Network
TB9100 base stations can be interconnected over an IP-based linking
infrastructure to form a TaitNet P25 network. Each base station in the
network belongs to a channel group. A channel group is a set of one or more
base stations. Any base station in the channel group can have a dispatch
console connected via its analog line (analog line license required). Base
stations in a channel group all require a digital line license.
