The following variants of the DIB-R5 are available:nDIB-R5 advancedThe DIB-R5 advanced offers up to eight TETRA carriers with cavity combiner andconsists of one or two equipment racks depending on the number of carriers.nDIB-R5 compactThe 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" equipmentracks.nDIB-R5 flexibleTxThe DIB-R5 flexibleTx provides up to four TETRA carriers in a compact rack and isoperated project-specific with external antenna coupling systems. DIB-R5 flexibleTx issuitable for space-saving installation in existing 19" equipment racks.Product description DIB-R5 flexibleTx23Operation 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 flexibleTxIn 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 amaximum 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 redundancyoptions to avoid "Single Points of Failure". On the hardware side, the transceivers, controlunit 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. Inaddition, DIB-R5 flexibleTx supports optimal reception of triple diversity with highest sen-sitivity. This optimizes the radio characteristic of the base stations and reduces thenumber of base stations that are required for covering a certain area.DIB-R5 flexibleTx can be configured depending on customer requests and networkrequirements and expanded, e.g. through additional carriers. This allows the mobile radionetwork to be adapted accordingly to meet new requirements and protect the currentinvestment.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" equipmentracks. 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 withthe help of the Precision Time Protocol (PTP). For this purpose, the base stations DIB-R5are supplied with the time synchronization from a central point.The continuous operation is also supported without satellite-based synchronizationsources. This allows a reliable operation even in underground areas or within buildingswithout the need of using an antenna for the reception of a satellite signal.The following figure shows the front view of the DIB-R5 flexibleTx with four TETRAChannel Units (CHU) and VAC power supply.

Figure 29: Antenna configuration with four CHUs and external antenna coupling system3.5 Redundancy optionsThe ACCESSNET-T IP provides numerous redundancy concepts to ensure the availa-bility of services and features reliably even in exceptional situations. The concept ofdesigning system functions, function blocks, network elements and connection routesredundantly, may be required to ensure site reliability and system reliability. Site andsystem reliability refers to the capability of the network to perpetuate the operation of theoverall system, even if one site or route drops out completely or partially (due to technicalfailure, 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 ancomplete network.If the DIB-R5 flexibleTx should be isolated from the rest of the network, it still providesmost of its features in local fallback operation. Especially security-related features likeauthentication 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 withDIB-R5 flexibleTx:nÄ Redundant main control channel (MCCH)nÄ Carrier redundancynÄ Controller redundancynÄ Fallback operationnÄ Stand-alone operationnÄ Redundant VAC power supplynÄ Redundant connection to the transport networknÄ Redundant synchronization (GNSS, PTP)The redundancy options can be combined with each other.Product descriptionRedundancy options DIB-R5 flexibleTx58 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 carrierwill take on this task. The MCCH is thus transferred. This transfer is made as often as thenumber of carriers that are available on the base station. In this case, the replacementcarriers for the MCCH keep on sending on their original frequency, not on the frequencyof the failed carrier. This frequency change is useful especially when interfering carriersaffect the MCCH frequency that was being used up to that point such that the MCCHdoes not suffer further interference after the frequency change.Irrespective of the number of carriers, each radio cell has only one MCCH, via which theterminals receive information, e.g. on adjacent radio cells. As a rule, the first channel ofthe first carrier of a base station is used as the MCCH, the three remaining channels ofthat carrier and all the channels of all the other carriers are used as voice channels or thePacket Data service. Redundant MCCH are enabled by default and apply to all the basestations with more than one carrier.3.5.2 Carrier redundancyTo 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 ismostly used in cases, in which only a few frequencies are available.3.5.3 Controller redundancyThe controller required for operating a base station can be of redundant design. For thispurpose two BSCUs (Base Station Controller Units, BSCU) are used, where one BSCU isin operation and the other is on standby. In the case of a failure of the active BSCU, thestandby 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 operationThe 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 basestation changes to fallback operation. In fallback operation, the base station in its radiocell still maintains the Base Station Function (BSF). Even in fallback operation, authenti-cation and authorization validation are ensured since the corresponding subscriber dataare 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 callsnIndividual calls (semi-duplex and duplex calls)nTransmission of SDS and status messagesProduct descriptionRedundancy options > Fallback operationDIB-R5 flexibleTx59Operation 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 callsnQueue, depending on the priority level of the callnRejection of a call from/to an unknown subscribernRejection with the reason "busy" if the subscriber is already making a call or the pri-ority of the incoming call is minornConfigurable call time limitnInactivity timer (ending semi-duplex calls after the configured inactivity time hasexpired)Fallback operation is the emergency operating mode of base stations in networks withcentralized switching architecture. The unavailability of network-wide services is signaledto the terminals and taken into account by them during the cell selection.3.5.5 Stand-alone operationThe radio coverage of base stations with Switching Controller Function (SCF) in networkswith distributed switching architecture continues to be ensured if they lose the connectionto 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 StationFunction (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 withdistributed switching architecture. The unavailability of network-wide services is signaledto the terminals and taken into account by them during the cell selection. Depending onthe project requirements, the signaling can be switched off upon demand.3.5.6 Redundant VAC power supplyFor the reliable power supply, DIB-R5 provides two redundancy options for VAC powersupply to ensure operation of the base station at all times:nÄ Redundant rectifier modules (Power Supply Module, PSM)nÄ Redundant power supply linesBoth 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 (PowerSupply Module, PSM) and ensures the operation of DIB-R5 if one PSM should fail. Theactive and the redundant PSMs are all in operation in this case and divide the loadamong them. In case of a failure, the load on the remaining PSMs is increased accord-ingly.Product descriptionRedundancy options > Redundant VAC power supplyDIB-R5 flexibleTx60 Operation Manual 90DIBR5flexibleTxOM02 - 1.2
In the combination with redundancy option "Redundant power supply lines", two PSMseach are supplied by one power supply line.3.5.6.2 Redundant power supply linesThe power supply continues to be ensured by a redundant power supply line on site andsecures the operation of the DIB-R5, even if a supply line should fail or the requiredvoltage range is underrun. This is particularly meaningful in difficult environments inwhich, 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 intoaccount in the site planning.3.5.7 Redundant connection to the transport networkWith the redundant connection to the transport network, the connection to all networkcomponents 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 beingobtained 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 toexternal influences, a switch is automatically made to the network time.Product descriptionRedundancy options > Redundant synchronization (GNSS, PTP)DIB-R5 flexibleTx61Operation Manual 90DIBR5flexibleTxOM02 - 1.2

Check the circumferential range of vision of the GNSS antenna.➔ The visual inspection has thus been completed.4.3.6.2 GNSS operational monitoring (via NMC-511 FaultManager)The function of the GNSS receiver and the detectable GNSS satellites are monitored bythe DIB-R5 flexibleTx based on the GNSS data received.Using the NMC‑511 FaultManager network management client, faults occurring in anACCESSNET-T IP network can be detected and localized rapidly. This facilitates promptfault elimination.All network constituents and connections of an ACCESSNET-T IP are monitored via theNMC-511 FaultManager. Operating states and faults are detected by the network man-agement system and visualized via the connected workstations, on which the NMC-511FaultManager is installed and enabled.The NMC-511 FaultManager displays the operating states and faults of the network con-stituents in the respective network in an alarm status list. This makes permanent networkmonitoring possible.The procedures for this purpose are described in corresponding documents, refer to thefollowing table.Required product documentsProduct Document typeNMC-511 FaultManager User manualIn the NMC-511 FaultManager the operating conditions and errors on network constitu-ents are represented by so-called alarm objects.Alarm objects provide alarms/statuses for properties of hardware and software compo-nents. In addition, alarm objects contain information that aids in the context of fault man-agement in the evaluation, localization and removal of errors.Alarm objects always have an alarm status, alarm status changes are notified via eventsand visualized in the NMC-511 FaultManager.OperationFunction tests and operational monitoring > Function tests and GNSS operational monitoringDIB-R5 flexibleTx73Operation Manual 90DIBR5flexibleTxOM02 - 1.2
