NGT Transceiver System Technical Service Manual
junction box
The unit in a transceiver to which a handset, 2010 RF Unit, speaker
and related devices are connected. The junction box receives the
instructions that a user enters through the handset and sends these
instruction to the relevant devices.
Master Bus mode
A CIB operating mode in which a CIB device, e.g. a 2010 RF Unit,
supplies power and TDM audio synchronisation pulses to the bus.
NGT remote
interface
A device that converts CIB audio, control and status signals to and
from RS232 data to enable interfacing with a line modem.
PTT button
The press-to-talk button, located on the left side of the handset.
This button enables you to communicate during voice calls, switch
mute off, cancel voice calls prior to the point where voice can be
transmitted, cancel calls where data is being transmitted, and exit
out of editable screens without saving changes.
remote control
junction box
A device that is used in a remote control system to interface with
other equipment including a modem or a radio/telephone
interconnect unit.
remote control
NGT system
A fixed base station that consists of a control site and transceiver
site. The control and transceiver sites communicate via a modem at
each site. This enables the transceiver site to be located in an
electrically quiet area for more reliable transmission with less noise
interference.
RF unit
The unit in a transceiver that modulates audio signals onto radio
frequencies that can be transmitted on air, and that demodulates the
radio frequencies it receives into audio signals.
signalling rate
The rate at which data is transmitted (this remains constant at
2400 bps).
Slave Bus mode
A CIB operating mode in which a CIB device, e.g. a junction box,
sources its power supply and TDM audio synchronisation pulses
from the bus.
throughput
The average data transfer rate between stations (this varies with
different channel conditions).
transceiver
The unit that modulates audio signals onto radio frequencies that
may be transmitted on air, and that demodulates the radio
frequencies it receives into audio signals. A transceiver comprises
an RF unit, handset, speaker, and appropriate connecting cables.
Transceivers that use a 2010 RF Unit also include a 2030 Junction
Box.
transceiver site
The location of the RF unit in a remote control NGT system. This
site is selected for its low electrical noise and good HF
propagation.
transmission
protocol
The method used by a modem to transmit and receive information.
