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. DIB-R5 compact is suitable for space-saving installation in existing 19" equipment racks. The hardware design of DIB-R5 features a modular layout. This allows hardware components to be replaced or added during ongoing operation. Operation Manual 90DIBR5advancedOM02 - 1.0 19 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.

Operation Manual 90DIBR5advancedOM02 - 1.0 59 DIB-R5 advanced Product description 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: n n n n n n n n 60 Ä Redundant main control channel (MCCH) Ä Transceiver redundancy Ä Controller redundancy Ä Fallback operation Ä Stand-alone operation Ä Redundant VAC voltage supply Ä Redundant connection to the transport network Ä Redundant synchronization (GNSS, PTP) Operation Manual 90DIBR5advancedOM02 - 1.0 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. Operation Manual 90DIBR5advancedOM02 - 1.0 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: n n n n n n n n n n n 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. 62 Operation Manual 90DIBR5advancedOM02 - 1.0 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.
