1INTRODUCTION
MAGIC TBR System is a compact and cost-efficient solution for the DAB tunnel
provisioning. A major feature of the system – as requested in the EU Tunnel
Directive 2004/54/EC – is the break-in possibility in case of emergencies or also for
purely informative announcements.
1.1 Conventions
In this manual the following conventions are used as text markers:
The TIP symbol marks information which facilitates the operation of the system in
its daily use.
The Note symbol marks general notes to observe.
The Attention symbol marks very important advice that is absolutely to observe. In
case of non-observance malfunctions and even system errors are possible.
1.2 Safety
The unit described has been designed to the latest technical parameters and
complies with all current national and international safety requirements. It
operates on a high level of reliability because of long-term experience in de-
velopment and constant and strict quality control in our company.
In normal operation the unit is safe.
However - especially if daily routine and technical errors coincide - some potential
sources of danger for person, material and optimal operation remain.
This manual therefore contains basic safety instructions that must be observed
during configuration and operation. It is essential that the user reads this manual
before the system is used and that a current version of the manual is always kept
close to the equipment.

1.3 General Safety Requirements
To keep the technically unavoidable residual risk to a minimum, it is absolutely
necessary to observe the following rules:
•Transport, storage and operation of the unit must be under the permissible
conditions only.
•Installation, configuration and disassembly must be carried out only by trained
personal on the basis of the respective manual.
•The unit must be operated by competent and authorised users only.
•The unit must be operated in good working order only.
•Any conversions or alterations to the unit or to parts of the unit (including
software) must be carried out by trained personnel authorised by the ma-
nufacturer. Any conversions or alterations carried out by other persons lead
to a complete exemption of liability.
•Only specially qualified personnel are authorised to remove and override
safety measures, and to carry out the maintenance of the system.
•External software is used at one’s own risk. Use of external software can af-
fect the operation of the system.
•Use only tested and virus-free date carriers.

1.4 Construction
The functions of MAGIC TBR are implemented in a single 19” x 2U unit which is
designed for mounting in 19” racks. The front keypad and display of the system
allow a basic configuration of the most important parameters like IP address,
operating mode etc. Additionally, status information can be displayed via five LEDs.
For monitoring purposes, a Phones interface with a 6.3 mm jack is available.
Figure 1: MAGIC TBR Front View
For high reliability the systems have two integrated redundant wide area power
supplies. By default, a system can handle one Ensemble. Optionally, a second
module can be equipped to use two independent Ensembles.

1.5 Functionality
MAGIC TBR is implemented on a signal processor-based hardware platform which is
assembled in an optimised way and achieves best values in terms of power
consumption and reliability. The standard system has a demodulator/modulator
module for one Ensemble. If required, the system can be equipped with a further
module for a second Ensemble. Both Ensembles are completely independent from
each other – a separate break-in is also possible. For the break-in function per
ensemble three encoders are permanently running: one DAB+ and two DAB
Encoder allow you to replace all Audio service in any configuration regarding
bitrate, sampling frequency etc. The break-in signal can be monitored via a
Monitoring Decoder.
Repeater and Remodulator Function
In the standard operation mode, the system functions as classic Repeater (see
Figure 3). The DAB Ensemble is received by an antenna outside the tunnel, is
filtered digitally and processed. Via the tunnel antenna the signal is broadcasted
again. A GPS signal is not required for this function. However, inputs are available
for future extensions.
Depending on local situations (e.g. bad reception conditions) it can be helpful to use
the system permanently in Remodulator mode (see Figure 4). This mode can also
be used during configuration to adjust and optimise the antenna signals at a tunnel
entry.
Figure 3: Repeater Mode

INTRODUCTION
11
Voice Break-In Function
During the repeater operation the received Ensemble is analysed permanently to
always have the current Multiplex Configuration Information (MCI) available – even
after reconfigurations.
In case of a necessary voice break-in all DAB and DAB+ Audio sub channels are
automatically replaced by the emergency signal. The signal will be completely
remodulated (see Figure 4).
The encoder bitrate of the break-in signal depends on the currently lowest bitrate
of all Audio sub-channels in an ensemble.
The complete Multiplex is fully replicated and replaced frame-synchronously. From
the view of a DAB Radio a continuous signal is received in terms of data rate,
sampling frequency, error protection, but also CIF Counter, time etc.
In this way it is guaranteed that the DAB receiver does not lose the synchronisation
or even re-scans the DAB band.
In parallel, PAD data can be transmitted as Slideshow and/or as Dynamic Label so
that the respective information can also be presented visually.
If a car driver listens to another medium (e.g. CD), the receiver can be switched
automatically to DAB radio via an appropriate alarm signalling (if the receiver
supports this feature).
The break-in trigger is in general realised via a TTL input signal, an IP SNMP
command or optionally via a remote VoIP telephone call.
Beside live break-in, multiple predefined break-in signals – together with a Dynamic
Label (DL) and a Slide Show (SLS) – can be stored in the system.

2.1 Mounting
With its dimensions (W ×H ×D) of 440 mm ×44,5 mm (1 U) ×273 mm the MAGIC
TBR system can be used either as desktop device or mounted in 19-inch racks.
Corresponding 19“mounting brackets are included in delivery.
When mounting the unit please keep in mind that the bending radius of the
connected cables is always greater than the minimum allowed value.
Although MAGIC TBR has an integrated fan for proper cooling, it is recommended
to have sufficient ventilation. The ambient temperature of the system should be
within the range of +5°C and +45°C. This threshold is specially to observe if the
system is inserted in a rack.
The temperature of the system can be displayed via the front panel under MENU >
STATUS INFORMATION or via the System Monitor of the web interface.
During operation humidity must range between 5% and 85%.
Incorrect ambient temperature and humidity can cause functional deficiencies.
Operation outside the threshold values indicated above leads to a loss of warranty
claim.
2.2 Connection to the main voltage
The system can be operated with main voltage in the range from 100 V to 220 V via
the integrated redundant power supplies. The line frequency can vary from 45 Hz
to 65 Hz. The maximum power consumption is not higher than 50 W if both
modules are equipped.

2.3 Earthing of the system
For EMC reasons an earthing via the earthing screw on the back side of the unit
must be carried out in either case.
Earthing
A lacking earthing can cause functional deficiencies within the unit. Because of the
‘pending’ potential, unlike the protective earth conductor potential, slight electric
shocks can occur by touching the rack. These are absolutely not dangerous;
however, they can be avoided totally by earthing.

Soft keys
2.4 Operational elements of the front keypad and display
The system has an illuminated graphical display with a resolution of 160 x 32 pixel
and 19 operating buttons.
On the right next to the display there are two soft keys whose current functions are
mentioned on the display. In the middle there are two cursor buttons
(upwards/downwards) as well as an OK button. The two phone buttons for
accepting/dropping have no special function except that you can display the IP
address of the system by pressing the DROP button.
The numerical pad supports also the ’*’- and ’#’-key in addition to the numerical
characters 0...9. For text entries the numerical pad can also be used as a normal
keypad.
Figure 5: Front keypad and display
2.5 Front status LEDs
MAGIC TBR has five LEDs for status indication:
•POWER green
oSystem is ready for operation
•SYNC yellow blinking
oRF input of one or both modules is not sufficient.
•ALARM red
oAt least one system alarm is pending
•INFO 1/2 yellow blinking
oActive break-in on ensemble 1/2

2.6 Wiring of the system
The wiring of MAGIC TBR is simple as shown in Figure 6.
You can use either LAN1 or LAN2 interface (or both). If you plan to use the VoIP
telephone call break-in possibility later, it is recommended to use the LAN2
interface since VoIP must run via LAN1.

2.7 Basic configuration via front panel
Although the most important functions are available via the front keypad and
display the configuration with a web browser is more comfortable.
However, at least one IP address must be configured on MAGIC TBR directly to
allow an access via a web browser:
•The standard IP address of the system is 192.168.96.102, the subnet mask is
255.255.255.0 and the standard control port 10000.
•To enable a connection with your PC, you have to be in the same subnet.
Enter an IP address at your system from your subnet or activate - to get the
correct settings automatically - DHCP (Dynamic Host Configuration Protocol),
if a DHCP server is available.
•To change the IP address manually at the system, press the soft key Menu
and then select system settings →LAN Interface →
LAN 1 settings → IP Address (or LAN 2 Settings if you have the system
connected via LAN 2 interface).
Enter now the desired IP address. When entering manually you have to be
sure that the IP address is not already used by another unit.
Maybe further settings are necessary (e.g. sub-net mask, gateway etc.).
In that case please contact your network administrator, who can tell you the
correct settings, or you use DHCP.
You can activate DHCP at the system via Menu →system settings →LAN
settings →DHCP.
You can identify the assigned or manually set IP address by pressing the DROP
button on the front keypad. The current IP address is displayed.
