3 Product description
The DIB-R5 base station family is a constituent of the TETRA mobile radio system
ACCESSNET-T IP and ensures the powerful and reliable mobile radio coverage of a spe-
cific area. Pioneering TETRA Release 2 support, particularly the TEDS technology
(TETRA Enhanced Data Service), render the DIB-R5 extremely attractive for all scenarios
in which a high degree of availability as well as high-speed data are absolutely neces-
sary. The TEDS data transmission allows transferring up to 150 kbit/s (gross bit rate)
securely and reliably via the air interface.
Figure 4: DIB-R5 family
The different variants of the base station family DIB-R5 meet customer and network
requirements in a perfect way. The following variants of the DIB-R5 are available:
nDIB-R5 advanced
The DIB-R5 advanced offers up to eight TETRA carriers with cavity combiner and
consists of one or two equipment racks depending on the number of carriers.
nDIB-R5 compact
The DIB-R5 compact offers up to four TETRA carriers with hybrid combiner and con-
sists of one or two compact racks depending on the number of carriers.
DIB-R5 compact is suitable for space-saving installation in existing 19" equipment
racks.
nDIB-R5 flexibleTx
The DIB-R5 flexibleTx provides up to four TETRA carriers in a compact rack and is
operated project-specific with external antenna coupling systems. DIB-R5 flexibleTx is
suitable for space-saving installation in existing 19" equipment racks.
Product description
DIB-R5 flexibleTx
23Operation Manual 90DIBR5flexibleTxOM02 - 1.2
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.

Channel Units (CHU) and VAC power supply. The following table describes the compo-
nents in greater detail.

3.2.6 Base Station Controller Unit (BSCU)
The Base Station Controller Unit (BSCU) is the control unit of the base station and
secures the connections inside of the DIB-R5 flexibleTx as well as to external network
constituents such as system controller nodes.
In addition, the BSCU receives and distributes the clock and time signals for the synchro-
nization of the base stations that are acquired via the integrated GNSS component
(Global Navigation Satellite System) with a connected antenna. GNSS includes all the
common systems, such as GPS, Galileo and Glonass. As an option, time is obtained via
the Precision Time Protocol (PTP) from a so-called reference time source (grandmaster
clock).
In addition, the BSCU is the interface to ACCESSNET-T IP and, as such, secures the
connection to other network constituents, such as system controller nodes, the network
management system (NMS) or applications.
The BSCU is a modular subrack for the DIB-R5 flexibleTx and is installed in the basic
rack. To increase availability, up to two BSCUs can be installed. If the first BSCU fails, the
redundant BSCU automatically assumes operation in order to quickly resume the radio
coverage. The failed BSCU can now be replaced during running operation.
The following figure shows the front view of the BSCU. The following table describes it in
detail.

3.5 Redundancy options
The ACCESSNET-T IP provides numerous redundancy concepts to ensure the availa-
bility of services and features reliably even in exceptional situations. The concept of
designing system functions, function blocks, network elements and connection routes
redundantly, may be required to ensure site reliability and system reliability. Site and
system reliability refers to the capability of the network to perpetuate the operation of the
overall system, even if one site or route drops out completely or partially (due to technical
failure, natural phenomena, acts of terrorism etc.).
The system technology allows flexible network structures and scalable redundancy solu-
tions that account for the different requirements for availability and capacity within an
complete network.
If the DIB-R5 flexibleTx should be isolated from the rest of the network, it still provides
most of its features in local fallback operation. Especially security-related features like
authentication and air interface encryption are supported. Hence, DIB-R5 flexibleTx ena-
bles a fully functional fallback operation and full redundancy for the important compo-
nents transceiver (CHU), control unit (BSCU) and power supply.
The following chapters describe the available redundancy options in conjunction with
DIB-R5 flexibleTx:
n
Ä
Redundant main control channel (MCCH)

Ä
Carrier redundancy
n
Ä

n
Ä
Fallback operation
n
Ä
Stand-alone operation
n
Ä
Redundant VAC power supply
n
Ä

Ä

Redundancy options
DIB-R5 flexibleTx
58 Operation Manual 90DIBR5flexibleTxOM02 - 1.2
3.5.1 Redundant main control channel (MCCH)
By redundant main control channels (MCCH) the operation of a base station is guaran-
teed even if the carrier with the MCCH drops out or should be disturbed.
If the carrier that provided the main control channel last drops out, an alternative carrier
will take on this task. The MCCH is thus transferred. This transfer is made as often as the
number of carriers that are available on the base station. In this case, the replacement
carriers for the MCCH keep on sending on their original frequency, not on the frequency
of the failed carrier. This frequency change is useful especially when interfering carriers
affect the MCCH frequency that was being used up to that point such that the MCCH
does not suffer further interference after the frequency change.
Irrespective of the number of carriers, each radio cell has only one MCCH, via which the
terminals receive information, e.g. on adjacent radio cells. As a rule, the first channel of
the first carrier of a base station is used as the MCCH, the three remaining channels of
that carrier and all the channels of all the other carriers are used as voice channels or the
Packet Data service. Redundant MCCH are enabled by default and apply to all the base
stations with more than one carrier.
3.5.2 Carrier redundancy
To increase the reliability of carriers or to ensure the Base Station Function (BSF), redun-
dant carriers can be used within a base station. These spare carrier ensure the radio cov-
erage on the frequency of the failed carrier if a carrier drops out. Carrier redundancy is
mostly used in cases, in which only a few frequencies are available.
3.5.3 Controller redundancy
The controller required for operating a base station can be of redundant design. For this
purpose two BSCUs (Base Station Controller Units, BSCU) are used, where one BSCU is
in operation and the other is on standby. In the case of a failure of the active BSCU, the
standby BSCU is automatically activated and takes on its function. In this way, the opera-
tion of the base station is always ensured.
3.5.4 Fallback operation
The radio coverage of base stations is also ensured if the base station loses the connec-
tion to an IP Node (IPN) with Switching Controller Function (SCF). In this case, the base
station changes to fallback operation. In fallback operation, the base station in its radio
cell still maintains the Base Station Function (BSF). Even in fallback operation, authenti-
cation and authorization validation are ensured since the corresponding subscriber data
are stored in the base station.
The connection to other network constituents is not possible in fallback operation, the fol-
lowing services and features, however, are available locally:
nGroup calls
nIndividual calls (semi-duplex and duplex calls)
nTransmission of SDS and status messages
Product description
Redundancy options > Fallback operation
DIB-R5 flexibleTx
59Operation Manual 90DIBR5flexibleTxOM02 - 1.2
nClass 2 and class 3 air interface encryption (encrypted voice and data communica-
tion)
nAuthentication (with respect to the base station)
nPriority calls, emergency calls, pre-emptive priority calls
nQueue, depending on the priority level of the call
nRejection of a call from/to an unknown subscriber
nRejection with the reason "busy" if the subscriber is already making a call or the pri-
ority of the incoming call is minor
nConfigurable call time limit
nInactivity timer (ending semi-duplex calls after the configured inactivity time has
expired)
Fallback operation is the emergency operating mode of base stations in networks with
centralized switching architecture. The unavailability of network-wide services is signaled
to the terminals and taken into account by them during the cell selection.
3.5.5 Stand-alone operation
The radio coverage of base stations with Switching Controller Function (SCF) in networks
with distributed switching architecture continues to be ensured if they lose the connection
to all other network constituents with SCF. In this case the base station switches to stand-
alone operation.
In stand-alone operation, the base station in its radio cell will perpetuate the Base Station
Function (BSF) as well as all the other local services and gateways (Application Gateway
(AGW) and/or Packet Data Gateway (PGW)). As opposed to fallback operation, in stand-
alone operation Call Detail Records (CDR) will still be generated.
Stand-alone operation is the emergency operating mode of base stations in networks with
distributed switching architecture. The unavailability of network-wide services is signaled
to the terminals and taken into account by them during the cell selection. Depending on
the project requirements, the signaling can be switched off upon demand.
3.5.6 Redundant VAC power supply
For the reliable power supply, DIB-R5 provides two redundancy options for VAC power
supply to ensure operation of the base station at all times:
n
Ä
Redundant rectifier modules (Power Supply Module, PSM)
n
Ä
Redundant power supply lines
Both redundancy options can be combined for the highest possible reliability.
3.5.6.1 Redundant rectifier modules (Power Supply Module, PSM)
The power supply continues to be ensured through redundant rectifier modules (Power
Supply Module, PSM) and ensures the operation of DIB-R5 if one PSM should fail. The
active and the redundant PSMs are all in operation in this case and divide the load
among them. In case of a failure, the load on the remaining PSMs is increased accord-
ingly.
Product description
Redundancy options > Redundant VAC power supply
DIB-R5 flexibleTx
60 Operation Manual 90DIBR5flexibleTxOM02 - 1.2
In the combination with redundancy option "Redundant power supply lines", two PSMs
each are supplied by one power supply line.
3.5.6.2 Redundant power supply lines
The power supply continues to be ensured by a redundant power supply line on site and
secures the operation of the DIB-R5, even if a supply line should fail or the required
voltage range is underrun. This is particularly meaningful in difficult environments in
which, for example, the infrastructure on site is unreliable. With this redundancy option,
one power supply line supplies one AC Power Distribution Module (APDM) in each case.
If this redundancy option is selected, a second power supply line must be taken into
account in the site planning.
3.5.7 Redundant connection to the transport network
With the redundant connection to the transport network, the connection to all network
components continues to be ensured in case of a failure of the IT infrastructure (e.g.
router).
3.5.8 Redundant synchronization (GNSS, PTP)
The clock and time signals required for the synchronization of base stations are being
obtained in parallel via a connected GNSS antenna and as an alternative via the Preci-
sion Time Protocol (PTP). If the satellite signal should no longer be available due to
external influences, a switch is automatically made to the network time.
