The hardware design of DIB-R5 features a modular layout. This allows hardware compo-
nents to be replaced or added during ongoing operation.
Properties of the DIB-R5 flexibleTx
In each compact rack DIB-R5 flexibleTx offers space for four TETRA Channel Units
(CHU), which are each providing one TETRA carrier. Thus offers DIB-R5 flexibleTx a
maximum of 16 radio channels to the radio subscribers that can be used simultaneously.
To increase the availability, DIB-R5 flexibleTx can be equipped with different redundancy
options to avoid "Single Points of Failure". On the hardware side, the transceivers, control
unit and power supply can be designed redundantly. Furthermore, additional software-
based redundancy options are available that further increase the reliability of features.
DIB-R5 flexibleTx is used project-specific with external antenna coupling systems. In
addition, DIB-R5 flexibleTx supports optimal reception of triple diversity with highest sen-
sitivity. This optimizes the radio characteristic of the base stations and reduces the
number of base stations that are required for covering a certain area.
DIB-R5 flexibleTx can be configured depending on customer requests and network
requirements and expanded, e.g. through additional carriers. This allows the mobile radio
network to be adapted accordingly to meet new requirements and protect the current
investment.
Due to the compact dimensions and the low weight, the DIB-R5 flexibleTx can be opti-
mally integrated into existing communication systems, e.g. into standard 19" equipment
racks. The compact design also eases transport, which can be undertaken using the inte-
grated carrying handles if necessary.
For time synchronization, the DIB-R5 flexibleTx can be operated with satellite-based syn-
chronization, e.g. GPS, Galileo and Glonass (Global Navigation Satellite System, GNSS).
As an alternative, the synchronization via the IP transport network can be carried out with
the help of the Precision Time Protocol (PTP). For this purpose, the base stations DIB-R5
are supplied with the time synchronization from a central point.
The continuous operation is also supported without satellite-based synchronization
sources. This allows a reliable operation even in underground areas or within buildings
without the need of using an antenna for the reception of a satellite signal.

nents in greater detail.
