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.

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.
