Product description
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 specific area. Trendsetting TETRA Release 2 and TETRA Enhanced Data Service (TEDS)
support make the DIB-R5 extremely attractive for all scenarios in which a high degree of
availability as well as high speed data are a must. 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 DIB-R5 base station family meet the customer and network
requirements in a perfect way. The following variants of the DIB-R5 are available:
n DIB-R5 advanced
The DIB-R5 advanced offers up to eight TETRA carriers with cavity combiner.
DIB-R5 advanced consists of one or two equipment racks depending on the number
of carriers.
n DIB-R5 compact
The DIB-R5 compact offers up to two TETRA carriers with hybrid combiner.

Product description
DIB-R5 advanced
In each equipment rack DIB-R5 advanced offers space for four TETRA Channel Units
(CHU), which are each providing one TETRA carrier. By using a second equipment rack,
up to eight carriers are supported. Thus offers DIB-R5 advanced a maximum of 32 radio
channels to the radio subscribers that can be used simultaneously. To increase the availability, DIB-R5 advanced can be equipped with different redundancy options to avoid
"Single Points of Failure". On the hardware side, the transceivers, control unit and voltage
supply can be designed redundantly. Furthermore, additional software-based redundancy
options are available that further increase the reliability of features.
DIB-R5 advanced supports different system configurations of the antenna coupling
system, including motor-tuned cavity combiner. This enables individual and fast remote
frequency change. In addition, DIB-R5 advanced supports for optimal reception triple
diversity. 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 advanced 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.
For time synchronization, the DIB-R5 advanced compact can be operated optionally with
satellite-based synchronization, e.g. GPS, Galileo and Glonass (Global Navigation Satellite System, GNSS).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.
The following figure shows the front view of the DIB-R5 advanced with four TETRA
Channel Units (CHU) and DUPLEXER. The following table describes the components in
greater detail.

3.2.6 TETRA Channel Unit (CHU)
The TETRA Channel Unit (CHU) is the transceiver module of the DIB-R5 and provides
four radio channels for the voice and data transmission in transmitting and receiving
direction (uplink and downlink) via one carrier signal. A transceiver consists of transmitter,
receiver and transceiver software for the TETRA protocol and generates a modulated RF
signal (carrier) with which signaling data and payload between the base station and the
mobile stations are exchanged. In addition to providing the carrier signal, the CHU provides monitoring and control functions, with which the fan speed can be controlled
dynamically, for example.
The CHU is a modular subrack for the DIB-R5 advanced and provides one carrier. The
DIB-R5 advanced can be expanded in a flexible way by additional CHUs, up to four
CHUs can be installed in one equipment rack. A CHU can be replaced during ongoing
operation in case of malfunctions to quickly re-establish radio coverage.
The following figure shows the front view of the CHU. The following table describes it in

3.2.7 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 advanced as well as to external network
constituents such as system controller nodes.
Furthermore, the BSCU receives and distributes satellite-based clock and timing signals
for the synchronization of the base stations, which are acquired via the integrated GNSS
component (Global Navigation Satellite System) with 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 the ACCESSNET-T IP, with which network constituents such as switching nodes, the network management system (NMS) or applications are connected.
The BSCU is a modular subrack for the DIB-R5 advanced. To increase availability, up to
two BSCUs can be installed. A BSCU can be replaced during ongoing operation in case
of malfunctions to quickly re-establish radio coverage, if a second BSCU is in operation.
The following figure shows the front view of the BSCU. The following table describes it in
detail.

3.2.10 Cavity combiner
Combiners are used for combining several transmitting signals to a common transmitting
antenna. The transmitters are decoupled from each other so that no mutual interference
can occur.
The cavity combiner is used in DIB-R5 advanced for loss-free coupling of up to four carrier signals at one transmitting antenna. The cavity combiner is motor-tuned and allows
remote frequence changes.
The following figure shows the rear view of the cavity combiner. The following table

Redundancy options
Figure 36: Antenna configuration with four CHUs and TX FILTER
3.5 Redundancy options
ACCESSNET-T IP provides numerous redundancy concepts to ensure the availability 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 location reliability and system reliability. Location and system
reliability refers to the capability of the network to perpetuate the operation of the overall
system, even if one location 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 solutions that account for the different requirements for availability and capacity within an
complete network.
If the DIB-R5 advanced 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 advanced enables a fully functional fallback operation and full redundancy for the important components transceiver (CHU), control unit (BSCU) and voltage supply.
The following chapters describe the available redundancy options in conjunction with
DIB-R5 advanced:

Product description
Redundancy options> Fallback operation
The redundancy options can be combined with each other.
3.5.1 Redundant main control channel (MCCH)
By redundant main control channels (MCCH) the operation of a base station is guaranteed 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 will maximally be repeated as
often as the number of carriers that are available at 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.
Irrespective of the number of carriers, each radio cell has only one MCCH, via which the
mobile stations 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 Transceiver redundancy
To increase the system stability of carriers or to ensure the Base Station Function (BSF),
as many as two redundant transceivers can be used in one base station. If one transceiver fails, these spare transceivers ensure the radio coverage with the frequency of the
failed transceiver. Transceiver 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 designed redundantly. In this
case, two BSCUs (Base Station Controller Units) are used, whereby one BSCU is in
operation and the other is kept ready for operation (standby). In case of a failure of the
active BSCU or its ethernet connection, the standby BSCU is automatically switched to
active and takes over its function. This ensures continued operation of the base station.
3.5.4 Fallback operation
The radio coverage of base stations is also ensured if the base station loses the connection 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, authentication and authorization validation are ensured since the corresponding subscriber data
are stored in the base station.

61
DIB-R5 advanced
Product description
Redundancy options> Redundant VAC voltage supply
The connection to other network constituents is not possible in fallback operation, the following services and features, however, are available locally:
Group calls
Individual calls (semi-duplex and duplex calls)
Transmission of SDS and status messages
Class 2 and class 3 air interface encryption (encrypted voice and data communication)
Authentication (with respect to the base station)
Priority calls, emergency calls, pre-emptive priority calls
Queue, depending on the priority level of the call
Rejection of a call from/to an unknown subscriber
Rejection with the reason "busy" if the subscriber is already making a call or the priority of the incoming call is minor
Configurable call time limit
Inactivity 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 operating mode is signaled to the mobile stations
and taken into account by them for 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 standalone 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 standalone 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 operating mode is signaled to the mobile stations
and taken into account by them for the cell selection.Depending on the project requirements, the signaling can be switched off upon demand.
3.5.6 Redundant VAC voltage supply
For the reliable voltage supply, DIB-R5 provides two redundancy options for VAC voltage
supply to ensure operation of the base station at all times:
n Ä Redundant rectifier modules (Power Supply Module, PSM)
n Ä Redundant voltage supply feeds
Both redundancy options can be combined for the highest possible reliability.

DIB-R5 advanced
Product description
Redundancy options> Redundant synchronization (GNSS, PTP)
3.5.6.1
Redundant rectifier modules (Power Supply Module, PSM)
The voltage 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 accordingly.
In the combination with redundancy option "Redundant voltage supply feeds", two PSMs
each are supplied by one voltage supply feed.
3.5.6.2
Redundant voltage supply feeds
The voltage supply continues to be ensured on site by the redundant voltage supply
feeds and secures the operation of DIB-R5 even if a feed should fail or fall below the
required voltage range. This is particularly meaningful in difficult environments in which,
for example, the infrastructure on site is unreliable. With this redundancy option, one
Power Distribution Module (PDM), two in case of redundancy, is always supplied by a
voltage supply feed.
If this redundancy option is selected, a second voltage supply feed must be taken into
account in the location 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 Precision 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.

Checking operating states (via the NMC-511 FaultManager)
Using the NMC‑511 FaultManager network management client, faults occurring in an
ACCESSNET-T IP network can be detected and localized rapidly. This facilitates prompt
fault elimination.
All network constituents and connections of an ACCESSNET-T IP are monitored via the
NMC-511 FaultManager. Operating states and faults are detected by the network management system and visualized via the connected workstations, on which the NMC-511
FaultManager is installed and enabled.
The NMC-511 FaultManager displays the operating states and faults of the network constituents in the respective network in an alarm status list. This makes permanent network
monitoring possible.
Checking the operating statuses via the NMC-511 FaultManager requires an NMC computer that is configured accordingly, with installed NMC-511 FaultManager that is connected with the ACCESSNET-T IP.
Besides checking the respective hardware and software components, the application
connections between the network elements should also be checked to ensure the correct
connection.
