from the local control, the remote control and, optionally, the RMS system. It also generate
status information to the same units. The local control and status indicators are a part of the
TX Control unit.
All functions in the TX Control are based on digital hardware to ensure the highest integrity.
3.6 Remote Monitoring (RMS) Unit
The RMS unit contains the system microprocessor. It handles storage and read-out of monitor
parameters, measurements for maintenance and fault finding, and performs fault analysis to
isolate faults to line replaceable modules. It is also used to set monitor limits and transmitter
adjustments.
The RMM handles communication to local and remote RMS computers, and in addition it han-
dles a small display and keyboard for parameter setting and readout.
3.7 Remote Control Unit
The remote control unit is used in the tower or in the technical control room. It has indicators
for operating status as well as detailed warnings and an aural alarm device with reset. It can
control equipment on/off and change-over, and has an Access Grant-switch to allow remote
control from the RMS system.
The Remote Control Unit is connected to the ILS by one telephone pair cable.
3.8 Remote Slave Panel
The slave panel is connected to the remote control by a multipair wire. It is intended for use in
the control tower. It has indicators for normal / warning / alarm and has an aural alarm device.
in addition it can turn the equipment on and off, and has an aural alarm reset.
Optionally a slave panel with remote control functionality can be delivered.
3.9 Remote Maintenance Monitoring (RMM)
The NM7000 series has a built-in Remote Maintenance Monitoring system. This system con-
sists of the RMS system, remote PC terminals with the RMM program installed, and the local
keyboard/display. Figure 3-2 illustrates the RMM/RMS systems
