Introduction TetraNode Base Station System
Warnings and Cautions
Caution:
This manual contains important information concerning installation, maintenance
and user instructions for the R-8070 based TetraNode Base Station.
Read the following pages before installing or using the equipment.
Warning:
This Equipment MUST be connected to a SAFETY EARTH.
Warning:
Do NOT operate the TetraNode Base Station without a suitable high-power 50Ω
load(s) or correctly tuned antenna system being connected.
Warning:
Do NOT touch or disconnect live (in use) antennas – RF energy can cause burns!
Warning:
Always ensure that the equipment is turned off before disconnecting antenna
cables.
Warning:
If working on a partially running site (half online), be careful of live power and
RF connections.
Warning:
If connecting to floating power supplies take care to minimise touch-currents.
Correctly earthed supplies are preferred over floating supplies.

Introduction TetraNode Base Station System
Warning:
If dual power supplies are used for redundancy, ensure warnings are clearly
posted on the cabinet and double circuit isolators are provided.
Warning:
Do not connect equipment-room earth to the same earth used for the tower
lightning protection.
Warning:
Do NOT work on antenna cables or systems when there is any nearby/local
electrical storm activity.
Warning:
The protective earths within the TetraNode Base Station should be adequately
bonded to the electrical earth of the 19” rack cabinet and NOT to any lightning
protection system for transmitter-towers/antennas.
Warning:
The power supply for the TETRA Base Station is low-voltage, but is nonetheless
capable of delivering a hazardous energy level if short-circuited. Always
disconnect the power before working on this equipment or connected systems.
Warning:
All power installations must additionally comply with all local wiring
regulations.
Warning:
Do NOT fit 3rd party equipment into this cabinet. Operating the equipment with
non-Rohill-approved components inside invalidates all warranties and may
compromise your safety!

Introduction TetraNode Base Station System
Warning:
This device complies with part 15 of the FCC rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference,
and (2) this device must accept any interference received, including interference
that may cause undesired operation.
Warning:
Rohill Engineering B.V. is not responsible for any changes or modification not
expressly approved by the party responsable for compliance. Such modifications
could void the user's authority to operate the equipment.
Caution:
Service and /or maintenance of this equipment should only be carried out by
qualified and trained service technicians/personnel. Ensure cabinet and/or
equipment room is kept locked.
Caution:
This equipment is designed to transmit and receive RF signals for which a
license is normally required. Although the equipment complies with the
manufacturing requirements for such equipment, it is the responsibility of the
customer to obtain a suitable license and to ensure that local requirements and
compatibility issues are complied with.
Caution:
When testing a running base site, consider first the impact on users before
disconnecting equipment!
Caution:
The calibration of the crystal reference in the TBS-SYN can be detuned by
mechanical shock. References so affected must be reconnected to a GPS signal
until auto-calibration has settled and corrected any errors.

Introduction TetraNode Base Station System
Caution:
The transmitter output and receiver input filters are qualified by Rohill for their
high performance and form part of the output filtering circuit. They must not be
replaced with alternatives nor be manually re-tuned.
Caution:
12VDC is present on the receiver inputs of the R-8070. Do NOT short circuit the
receiver inputs. Do NOT connect receivers to test equipment without a DC block.
Caution:
All unconnected connectors should remain unconnected unless otherwise stated
by Rohill. Unconnected connectors inside a BSS do not require any termination
either by design or by function.
This statement is not applicable for connectors meant for external connections
such as the ANT (antenna) output of combiners, power supply.

Introduction TetraNode Base Station System
1 Introduction
1.1 Scope
This manual covers the R-8070 based TetraNode Base Station System. Available
options, a technical description and guidelines for its installation, operation and
maintenance are provided.
This manual covers all available frequency band variants and standard
configurations. Special configurations and external components such as power
back up systems and back-haul networks are not covered by this manual.
Guidance notes (for information) are written in italics.
Where specifications are given, these are for illustration as they may be subject to
change. The definitive figures should be checked on the appropriate product data
sheet.
The R-8070 transceiver MUST be operated in combination with the supplied
antenna combiner system. i.e. The antenna filters, combiners and low noise
amplifier are now part of the transceiver.
1.2 Base Station System overview
A TetraNode Base Station System is designed to provide the radio frequency
carriers for one TETRA base site. As standard it consists of one cabinet
containing one to four R-8070 transceivers and all the associated cabling, antenna
combining, synchronisation unit(s), optional fall-back site controller, line
interfacing and optional power supplies.
All Rohill Base Stations are supplied fully assembled and tested. It remains only
for antenna connections, power and system (network) connections to be made.

2 System Options
2.1 Number of carriers
The standard number of carriers per cabinet is two or four. However cabinets can
be sub-equipped for one or three carrier configurations. If more than four carriers
per site are required, then multiple cabinets should be co-located.
2.2 Cabinet
The standard R-8070 Base Station System (1 to 4 carriers) is supplied in a
1670mm high (32U internal) 19” rack unit. 600x600mm footprint with lockable
front and rear doors. Colour light grey (RAL 7047). Front door is solid. Rear door
is ventilated (exhaust air) top and lower/middle. Main air inlet is under rack, main
air exhaust is lower/middle of rear door.
2.3 Power supply
TetraNode Base Station System
The standard R-8070 Base Station System is supplied from a single +24V
(nominal) DC connection. DC range is 18-36VDC negative earth. 3 and 4 carrier
systems are dual-redundant supply as standard. Switching power control and
backup (e.g. UPS) must be provided separately and externally. Supply options are
available for:
• 18-36VDC (nominal +24VDC) negative earth
• AC mains. Input range 100-240VAC 50/60Hz
The system is also prepared for 36-58VDC (nominal -48VDC) positive earth –
please enquire. Configurations can be:
• non-redundant, or
• dual-redundant
