2.3.2 Electromagnetic compatibility
With specific products, e.g. HF radio equipment, increased electromagnetic radiation
may occur as a consequence of operation. Taking into consideration that unborn life is
increasingly worthy of being protected, pregnant women should be protected through
appropriate measures. People with personal medical devices such as cardiac pacemak-
ers and hearing aids can also be endangered by electromagnetic radiation. The opera-
tor is obliged to assess workplaces with a considerable risk of exposure to radiation and
to avert any hazards.
2.3.2.1 Electromagnetic compatibility for Europe
In proper state and when operated properly, the product complies with all the require-
ments in respect of interference radiation according to ETSI EN 301 489-18. The con-
nections conducting HF signals must neither be manipulated nor damaged.
When using the product with active typical transmitters, the requirements of EN 50385
in respect of the health and safety of a user or any other person in high-frequency fields
are met. Compliance with EN 50385 is achieved as of a minimum distance of 1.5 m to
the transmitting antenna. A typical transmitter is made up of an omni-directional trans-
mitting antenna with an antenna gain of 7.5 dBi installed on a mast with a height of 30 m
and connected to the base station through a 40-m cable.
2.3.2.2 Electromagnetic compatibility for North America
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide rea-
sonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio fre-
quency energy and, if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications. Operation of this equipment
in a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.

DIB-500 R4.1 Product description
3 Product description
The Digital Indoor Base Station (DIB-500 R4.1) is used as a base station in
ACCESSNET®-T IP networks. The base station is responsible for radio coverage in a
defined radio coverage area. For this purpose, up to eight carriers are available
depending on the antenna coupling variant. It can thus provide as many as 32 radio
channels (four radio channels per carrier) for the communication of the mobile terminal
equipment, via which voice and data is/are transmitted in accordance with the TETRA
standard (Terrestrial Trunked Radio).
In addition, in networks with a distributed switching architecture, the DIB-500 R4.1 can
take on the routing function and thus act as a full system controller node. Moreover, fur-
ther functions are available; applications, for example, can be connected directly to the
ACCESSNET®-T IP by means of an IP connection.
The carriers are provided via the transceiver module TETRA Indoor Base Transceiver
(TIB) that can accommodate up to two carriers. Two TIB transceiver modules may be
incorporated in the equipment rack of the DIB-500 R4.1, thus providing four carriers.
From five carriers, a second equipment rack is used, which can also provide up to four
carriers.
Two TETRA antenna connections and one GPS antenna connection (Global Position-
ing System, GPS) are available for connecting antennas. Internally, the antennas are
coupled via the antenna coupling system. In the FlexibleTx variant, project-specific
external antenna coupling systems can be used for this purpose. For optimum reception
properties, antenna diversity is available.
Depending on the requirement, the ACS can provide the following antenna connection
variants:
|Hybrid
|Cavity
|High Power or
|FlexibleTx
For communicating with other base stations and with the IP Node (IPN) network ele-
ment, the DIB-500 R4.1 features Ethernet interfaces for linking to the IP transport net-
work.
If all the connections to the other network constituents break down during operation, the
DIB-500 R4.1 ensures radio operation within its own radio cell. If the DIB-500 R4.1 is
operated with a separate routing function in networks with a distributed switching archi-
tecture, the base station additionally collects call detail records (CDR).

For specifications on the cables required, please refer to section 5.1.2 on page 32.
Responsibility for the installation, commissioning and maintenance of an
antenna system
The operating company is responsible for the proper installation, commissioning and
maintenance of an appropriate antenna system, unless this is an integral part of the
contract concluded with Rohde & Schwarz Professional Mobile Radio GmbH. An
installer who may have been entrusted with the installation/commissioning and/or main-
tenance of the antenna system is responsible for complying with all the applicable
requirements and for the metrological tests required afterwards. In addition, equipment
for protecting the antenna cables against lightning must be provided.
4.1.6 Adjustment of the GPS antenna
Each equipment rack features a separate GPS antenna connection but only one GPS
antenna is required per network element DIB-500 R4.1. For network elements made up
of multiple equipment racks, the clock and time reference signals are synchronized.
Additional GPS antenna recommended
For DIB-500 R4.1 with more than two TIB transceiver modules and controller redun-
dancy, the use of an additional GPS antenna is recommended to ensure the GPS syn-
chronicity of the entire base station in case the active controller fails.
Without GPS satellite reception the proper operation of the DIB-500 R4.1 is ensured for
one year (depending on the ambient conditions) if a GPS signal was received before at
least once.
The 24 GPS satellites in total are not positioned geostationarily. For this reason, the
location of the GPS antenna must be chosen to ensure that the reception is not
impaired/disturbed by any obstacles.
It is best to install the GPS antenna on the roof of a building. It is also possible to install
it on an upright mast with a diameter of 60 mm. Irrespective of the installation method
used, always ensure a good circumferential visibility (angle for unobstructed sight of the
sky according to the recommendations of the manufacturer). The angle of the GPS
antenna supplied is 90 °. The orientation of the GPS antenna must ensure that at least
four satellites are received.
A minimum distance of 5 m must be kept between the GPS antenna and the Tx
antenna(s) since the decoupling established must be as large as possible - especially
for carriers in the range of 393 to 395 MHz, since the fourth harmonic wave in this case
is in the range of the received signal of the GPS signal.
For specifications on the cables required, please refer to section 5.1.2 on page 32.

An air-conditioning system can be used to control the temperature in the operation
room. The thermal dissipation loss of the product as well as of other technical equip-
ment operated in the operation room must be taken into consideration when controlling
the operating temperature. The maximum thermal dissipation loss corresponds to the
power consumption, refer to Tabelle 5.5 on page 30.
Responsibility of the operator
The use of an air conditioning system is advisable. The operating company is responsi-
ble for the proper installation and the operation of an appropriate air conditioning sys-
tem.

The following requirements must be met for being able to operate the product as
intended:
|The service room must be dry and closed to maintain a constant relative humidity of
50 %, if possible (recommended for slowing down the aging process of integrated
components).
|Unimpaired air supply to the equipment rack must be ensured.
The ventilation concept of the DIB-500 R4.1 provides for the optimum vertical ventila-
tion of the incorporated components inside the equipment rack. In this case, the air is
drawn in through the perforated equipment rack door and all the dirt and dust particles
are filtered out via the ventilator unit. Subsequently, the air is discharged through the top
of the perforated equipment rack door.
4.2.3 Dust concentration
The product was developed for use in a municipal industrial area. The average dust
concentration per year in a municipal industrial area amounts to a value of up to
200 µg/m³. The dust concentration in the operation room of the product must not
exceed this value.
Operation rooms that are not completely closed require an appropriate housing.
To ensure a minor dust concentration, the use of an overpressure system for the opera-
tion room is advisable.

bonding appliances of telecommunications equipment can be found in ETSI EN 300
253 V2.1.1.
4.3.1 Overvoltage protection of the equipment rack (VAC/VDC)
Each equipment rack (apart from the equipment rack(s) of the cavity variant) of the
DIB-500 R4.1 features a connection panel, via which the integrated components are
supplied with voltage and grounded.
The protective ground connection of the voltage supply connector of the equipment rack
is not a sufficient protection of the system against pulse voltages, such as those that
occur during a thunderstorm.
For this reason, the equipment rack must be protected against overvoltages at the
installation site through appropriate grounding equipment to prevent damage to the sys-
tem technology.
Responsibility for the installation, commissioning and maintenance of a ground-
ing and overvoltage system
The operating company is responsible for the proper installation, commissioning and

DIB-500 R4.1 Requirements concerning the operation room
Grounding and overvoltage protection
To protect the GPS antenna input against overvoltage (caused by lightning, for exam-
ple), a GPS protector is optionally available that should be used in combination with a
lightning surge protector to provide for optimum overvoltage protection. The GPS pro-
tector can be ordered separately.
GPS overvoltage concept
When using the GPS protector, the GPS supply lines at the entry into the building
should be safeguarded against high overvoltages by a grounded lightning surge protec-
tor.
Table 4.6 lists the requirements for the lightning surge protector.
It must also be ensured that all interfaces of the product are secured against transient
overvoltages. These short-term inductive, capacitive or static overvoltages of a few mil-
liseconds occur, e.g. because of adjacent interference sources, and can interfere with
voltage supply and signal feed lines.
Standards and Guidelines
For information on potential or required measures for installing safety equipment
against transient overvoltages for the VDC voltage supply, please refer to the standard
ETSI TR 100 283.
The required measures for installing safety equipment against transient overvoltages for
the VAC voltage supply are described in section 4.3.2 on page 29.

A UPS serves for ensuring uninterrupted power supply in the case of voltage fluctua-
tions or a temporary failure of the primary power supply. The dimensioning of the UPS
depends on the duration of the time that may have to be bridged as well as on the con-
sumer power the UPS needs to provide security for.
When dimensioning the cross section of the connecting cable between the UPS and the
product, be sure to keep the voltage loss of the connecting cable as low as possible.
Otherwise the UPS may not be able to provide the desired power failure bridging time.
The UPS cannot provide the power failure bridging time, for example, if the discharge
protection threshold of the UPS plus the voltage loss of the connecting cable is smaller
than the lower voltage supply limit value (refer to Table 5.2 on page 32) of the product
with battery supply.
Responsibility of the Operating Company
The use of an uninterruptible voltage supply (UPS) is advisable. The operating com-
pany is responsible for the proper installation and operation of appropriate uninterrupti-
ble power supply systems.
5.2.1.2 Cable specifications of voltage supply cables (VDC)

DIB-500 R4.1 Requirements concerning the electrical system
Voltage supply
One Schuko plug in compliance with CEE 7/VII for each integrated rectifier module is
included in the scope of delivery and already installed upon delivery. The voltage supply
cable(s) are identified according to the related rectifier module, e.g. "PSU1".
Removing Schuko plugs
The Schuko plug can be removed when the DIB-500 R4.1 system is to be connected to
a fixed connection (e.g. distributor box). In this case, the strand ends of the voltage sup-
ply cable/s must be fitted with end sleeves for strands.
5.2.2.2 Cable specifications of voltage supply cables (VAC)
In the version of the product/system with VAC voltage supply, one voltage supply cable
per rectifier module is available via the mounting frame. The voltage supply cable(s) is/
are routed out through the grommet of the equipment rack. This/these voltage supply
cable(s) is/are already connected to the mounting frame and can be connected to the
voltage source on site.
5.2.2.3 Fuse protection (VAC)
Each equipment rack (apart from the equipment rack(s) of the cavity variant) of the
DIB-500 R4.1 features a connection panel, via which the integrated components are
supplied with voltage and grounded.
Insufficient fuse protection of the power supply may impair the operation of the product.
The construction of automatic circuit breakers depends on the characteristics of the

In the case of a VAC voltage supply, the voltage supply source on site must be protected
by an appropriate overload protection for each supply line independent of the connec-
tion variant.
Table 5.7 describes the requirements concerning the overload protection on site by an
external fuse. This overload protection protects the cable between the voltage source
and the mains socket/fixed connection.
