Antenna coupling variants of the DIB-500 R4.1

3 Product description

In ACCESSNET®-T networks, the Digital Indoor Base Station (DIB-500) is used as a network element of the base station type. The base station is responsible for radio cov­erage in a defined radio coverage area. For this purpose, as many as eigh t carrie rs are available depending on the variant. It can thus provide as many as 32 radio channels (four radio channels per carrier) for the communication of the mobile terminal equip­ment, via which voice and data is/are transmitted in accordance with the TETRA stand­ard.
The TIB transceiver, of which multiple instances may be used depending on the required number of carriers is responsible for radio coverage TIB (TETRA Indoor Base Transceiver) suppor ted by the ACS antenna coupling system ACS (Antenna coupling system). For a location with eight carriers, for example, two equipment racks with two TIBs each (two carriers) and an ACS each are used. In th e sce na r io de scr ibe d , tw o Tx / Rx antennas will be used. For diversity reception, the reception paths between the two equipment racks will be connected.
Via the follwing interfaces the base station can be connected with other base stations and with network elements of the System Controller Node type (e.g. Digital Mobile eXchange, DMX):
| E1 connections, | IP connections (depending on the used system software [Package Version, PV])

3.1 Antenna coupling variants of the DIB-500 R4.1

Different antenna coupling variants of the Digital Indoor Base Station (DIB-500) are available. The selection of the corresponding antenna coupling system depends on the network requirements.
The following antenna interfaces are available for different network requirements:
| Hybrid variant
– Compact design – up to eight carriers per network element (distributed on two equipment racks), – high flexibility in frequency selection, – flexible frequency change.
| Cavity variant
– up to eight carriers per network element (distributed on two equipment racks), – higher transmitting power than hybrid variant.
| High power variant
– up to two carriers per network element, – Higher transmitting power than hybrid and cavity variants
Antenna diversity is available for optimal reception properties.

The network and hardware components integrate d into the TIB are described in d etail in the following chapters.
3.2.1.1 Multi Processor Server Unit (MSU)
The MSU is a hardware component. It serves as a hardware platform for the Processing Unit Controller (PUC) software component. It provides four Ethernet interfaces.
In addition, a GPS module is installed in the MSU that is responsible for providing the clock and time reference signals (synchronization) required for switching connections.
The MSU components are described in detail in the following sections.
28 Installation and Operation Manual 90DIB500IM02 – 5 .2
DIB-500 R4.1 Product description
Components of the DIB-500 R4.1
PowerPC
The PowerPC is a hardware component and an integral constituent of the TIB. The fol­lowing software components use the PowerPC as the hardware platform:
| Switching and Routing Server (SRS) | Processing Unit Controller (PUC)
Switching and Routing Server (SRS)
The Switching and Routing Server (SRS) is a software component. It establishes the connection to an SRS of another network element via the Point-to-Point Protocol (PPP).
In this way, the components of the network elements in the radio system can communi­cate via IP to exchange signalling data. The SRS uses one or multiple channels of an E1 line and can thus connect several network elements with each other at the same time.
Processing Unit Controller (PUC)
The Processing Unit Controller (PUC) is a software component and serves for commis­sioning, configuring, controlling and monitoring the integrated hardware components of the TIB. The PUC makes the resulting data available to the Network Management Sys­tem via an SNMP agent.
The PUC is also responsible for the signalling between the transceivers and the TETRA Operation Server (TOS). The PUC forwards the signalling from the transceivers to the TOS or, the signalling from the TOS via the air interface back to the transceivers.
GPS module
The GPS module is a hardware subcomponent within the MSU. It is responsib le for p ro­viding the clock and time reference signals required for synchronizing the components within the network element. For this purpose, the time signal received from the PUC software component is processed and forwarded to the PowerPC as a reference signal. From there, the reference signal is distributed with the aid of the Network Time Protocol (NTP).
3.2.1.2 IntelPC
The IntelPC is a hardware component and an integral constituent of the TIB. The follow­ing software components use the IntelPC as the hardware platform:
| TETRA Operation Server (TOS) | Network Element Manager (NEM-523)
TETRA Operation Server (TOS)
The TETRA Operation Server (TOS) is responsible for the mobility management (regis­tration, group handling, authentication and call management with speaker monitoring, etc.). In addition, the TOS is responsible for the resource management for the radio channels, it manages the TETRA radio cell including control of the broadcast data.
Network Element Manager (NEM-523)
The Network Element Manager (NEM) is part of the network management system of ACCESSNET
®
-T. It administrates the network elements and facilitates the access to
the network components installed in the TETRA infrastructure.

Components of the DIB-500 R4.1
The NEM-523 server application is responsible for management functions and controls the downloads as well as the distribution of network resources. The NEM-523 is the remote station, via which the NMC-522 DownloadManager communicates while down­loading software or data. It is responsible for properly enabling a configuration or soft­ware and for a fallback to the previous configuratio n or software versio n in th e c as e of faults. The NEM-523 is the operative ma nager within th e network mana gement syste m. The redundancy management, e.g. is referred to as an operative function. If specific network resources are not available temporarily, the application will control switchover to the standby resources.
3.2.1.3 Synthesizer
The synthesizer is a hardware component and provides all the required clock pulses and frequencies. These are based on the standard cl ock puls e (G PS) pr ovided by the Multi Server Processor Unit (MSU).
3.2.1.4 Power supply
The power supply is a hardware component and provides the volt age supply for the TIB.
3.2.1.5 Receiver/transmitter (carrier)
A carrier is a hardware component consisting of a transmitter, a receiver and a TETRA protocol coder/decoder. Carriers are available in different frequency ranges as required. Up to two carriers can be installed in one TIB. One carrier gen erates the rad io chan ne l, via which the base station and the mobile terminal equipment exchange user data and signalling data.

3.2.2 Antenna Coupling System (ACS)

The antenna coupling system (ACS) is a network component for the Digit al Indoor Base Station (DIB). The ACS has been implemented in the form of a subrack for the equip­ment rack. Depending on the variant, an ACS permits the operation of two or four carri­ers on one Tx/Rx antenna. For operating more than four carriers, two ACS (integrated in two equipment carriers) can be connected with one another so that up to eight carrie rs on two Tx/Rx antennas are possible. For the diversity variants, the diversity reception is facilitated through further (Tx)/Rx antennas.
The following variants for different requirements are available:
| Hybrid variant | Cavity variant | High power variant
