7 Preparation for Operation
7.1 Introduction
The base station operation can be modified by the use of links and
programmable settings.
The base station can be configured for operation in the following basic
modes of operation:
■ Line-controlled base: The base station transmit audio and key is derived
via the system interface. Audio response is link-selectable.
■ Talk through repeater (voice): The receiver audio is directly connected
to the transmitter and the transmitter is keyed by the receiver gate.
Audio response in this mode is software-selectable.
■ Data repeater: The received data line is connected to the transmit data
line. receiver gate and transmitter key signals are not used.
■ RF modem: Data on the serial interface is connected to the transmitter
and the receiver.
■ TaitNet trunking.
7.2 Mode of Operation
This section shows how to set up the base station for various modes of
operation.
Examples are:
■ line-controlled base
■ talk through repeater
■ RF modem
■ data repeater
■ TaitNet trunking.
Where applicable, the procedure for setting any of the audio levels or other
adjustment points will be described, along with the procedure for measuring
a variety of parameters commonly monitored.
To verify the operation of the base station it is best to configure it as a line-
controlled base first. In this mode of operation the receiver and transmitter
modules can be independently tested because all the audio inputs and
outputs are accessible via the system interface connector. When the base
station has been tested as a line-controlled base, it is then a simple process to
change the links to the required mode of operation and perform any
additional functional testing required for that mode of operation.
