1 Introduction

1.1 Purpose of the ManualThis document is intended to give the information necessary for the installation of theNode B station in the Radio Network Subsystem (RNS).

It contains a description of all the necessary steps to install the Node B on site andintegrate it into the required infrastructure:– Power supply– E1/J1 - Network– Grounding– Receive / transmit antenna system– Alarm connections– Base constructions

For installation of equipment not supplied by Siemens (battery chargers, antennas,power supplies, microwave etc.) refer to site specific documentation or vendorinstructions provided with other equipment.

1.2 Tasks of the Node B StationsThe Node B Station performs the following main tasks in accordance with the require-ments of the UMTS standards:– Provides the RF-link connection to the User Equipment (UE)– Supports various cell types (omni and sector cells)– Provides the E1/J1 link connection (symmetrical twisted pair or coaxial cable is

used) and/or the STM-1 optical link connection to the Radio Network Controller(RNC)

1.3 System Operating BandsThe Frequency Division Duplex mode (FDD) implemented uses different frequencybands for uplink and downlink thus allowing symmetrical data traffic.– Downlink: 2110 MHz - 2170 MHz– Uplink: 1920 MHz - 1980 MHz– Channel spacing: 5 MHz

!Important!The declaration of CE conformity for the product is fulfilled if the setup and wiring arecarried out as described in the manual and the documents contained therein, such asinstallation instructions, cable lists, etc. Project-specific documentation should be takeninto account as appropriate. Deviations from specifications or unauthorized changes inthe setup, such as the use of cable types with less shielding, can lead to a violation ofCE safety requirements. In such cases, the declaration of conformity is rendered void.The responsibility for the resulting problems passes to the individual who caused the de-viation.



1.4 Installation PrerequisitesIt is required that the installer pays attention to all relevant national EMC standards.– EMF (electromagnetic fields) standard relevant for the choice of the antenna, the

placement of the antennasand the max. output power of the Node B (cell coverage).

– Use the correct material as described in this manual.– Installation according to the standards EN 50310 or ETS 300253, EN 50154 and the

statements in this manual.– The other equipment on site have to fulfill the relevant safety- and EMC standards

and must provide interfaces for connecting of external cables conformable to EMCinstructions.

The installation staff must have a basic knowledge of the relevant standards.The installation manual should be available for staff on site.

1.5 Handling of the ModulesAll boards and modules must be handled with extreme care as each one containselectrostatically sensitive devices (ESD).The modules are marked with the ESD-label.

Fig. 1.1 ESD Symbol

The modules are sensitive to static discharge.

Note:– Avoid handling the modules in a high-static environment– When handling the modules, do not touch connector contacts– An earthed high-impedance wrist strap must be worn when handling modules– Use the socket at the racks for wrist strap connection– The modules must be transported in appropriate packaging

1.6 Safety Instructions

Persons other than the maintenance personnel must not touch the devices inside theAC-Distribution. The AC-Distribution involves a high voltage and high current. Touchingit can lead to an electrical shock or accident.

Make sure not to touch parts of the Node B that contains components with high voltageor current. An inadvertent contact with any of these components can cause injury, death,and/or damage to the system.

Be sure to provide grounding where required. A failure to do so can lead to a systemfailure or electrical shock at the time of lightning.

When measuring voltage or current, take adequate insulating measures, such as cov-ering or winding the superfluous parts of the measuring terminal and tools with insulatingtape. Allowing the measuring terminal to touch another terminal or a short-circuit causedby a tool can lead to an electrical shock or accident.

Before making a connection with the DC-PDB, ensure that the power to the main andbattery circuit breaker is OFF. Making a connection with the DC-PDB when the poweris ON can lead to an electrical shock or accident.

Before making a cable connection, be sure to turn the switch on the power distributionboard to OFF. Otherwise, an electrical shock or accident can result.

Before making a cable connection, confirm the electric polarity. If the cable is connectedwith wrong polarity, an electrical shock or accident can result.

Make sure to follow the additional safety instructions in this manual.

1.7 Installation ToolsThe correct installation is carried out with the aid of the following tools:– Standard toolkit for BSS-installation– Spirit level– Torque spanner for SMC connectors (35 Ncm)– Torque spanner for SMA connectors (100 Ncm)– Screw driver for torx screws T8, T10, T20, T25, T30– Long screw driver for torx screws T30 (length 400 mm)– Engineer‘s spanners open ended for M12, M42 (SW 19, 65 mm)– Ratchet with inserts for nuts M4, M5, M6, M8, M10 (SW 7, 8, 10, 13, 17 mm)– Security torx bit IPR25 (Knürr part no. 4000031 98)– Screw drivers for hexagonal socket screw or hexagonal socket screw key SW 4 mm– Screw driver for slotted screw M3, M4, M5– Screw driver for pozi drive screws M3,M4, M5– A pair of scissors– Stripping knife for RF cables– 90˚ offset screw driver for torx screws T20– Blanket and knee pads (recommended)– Adjuster feed wrench M42 (SW65) (Knürr part no. 01.139.965.7)– Hammer and a suitable piece of wood– Insulated torque wrench for Torx T30 (6 Nm) and an open ended 17mm (20 Nm)– Torque wrench 32 mm (12-35 Nm) for 7/16” connectors

!Pay attention to the following safety instructions on high voltage and high current:

2.3 Site ConfigurationOperation of the NB-440 requires additional equipment on site:

Fig. 2.2 Site configuration NB-440

2.4 Construction View of NB-440The modules of the NB-440 station are housed in a rack with the dimensions1400 x 600 x 450 mm (H x W x D). The rack can be equipped with up to 6 TRX.The necessary space for installation is shown in Fig. 2.12.

The NB-440 rack contains the following modules:

Core Controller (CC):The Core Controller is built up of 4 boards: CPU board, ATM board, LIU board and theSTM-1 board.

Channel Coding Card (CHC):The main function of CHC is the decoding in uplink direction.

Repeater Card (REP):The REP card provides a multiplexing function for base band signals. The card sorts thedownlink signals from the CHC cards according to antennas and sends them to theTRX cards. The card also sends the signals from the TRX cards to the CHC cards inuplink direction.

Transceiver Card (TRX):

The TRX card features a transceiver base band block (TRX BB) and a radio frequencyblock (RF). The radio frequency block is composed of the transmitter block (TX) and thereceiver block (RX). Both TX and RX have diversity configuration. The transmitter blockconverts baseband signals into RF signals and the receiver block converts RF signalsinto base band signals.

Duplexer Amplifier Multi Coupler (DUAMCOF):A duplexer combines the transmit and receive paths to the common antenna connector.The receive and transmit part of the duplex filter, respectively, provide a substantial partof the transmit and receive band filtering that is required.

Linear Power Amplifier(LPA):The LPA is the RF power amplifier. An LPA is capable of supporting one (LPA-SCF) ortwo carriers (LPA-MCF).In case of the two carrier LPA the signal path consists of a combiner and a poweramplifier enabling two separate signals from TRXs to be combined before application.

Over Voltage Protection and Tracer (OVPT):Protects the E1 and J1 ports of the Iub interface and the external synchronisation clockinput of the Node B from overvoltage and provides interfaces for connection of externalmonitoring equipment without interruption.

Tower Mounted Amplifier( TMAF):The TMAF is an (optional) RF unit (external to the Node B rack) which provides themeans to feed the overall Node B downlink signal to one TX/RX antenna and to amplify,with low noise figure, the overall Node B uplink signal coming from the same TX/RXantenna.

The numbers of installed modules (exepted CC) are subject to modification, it dependson the number of TRXs and the cell configuration on site.

NB-440 is fed by an external -48 V DC source.The required link equipment for the fixed link to the fixed public telephone network(can be microwave or NTPM) must find place in a separate shelf on site. Type and layoutof the shelf depends on customer requirements.

For further information about the hardware architecture refer to the “Technical Descrip-tion UTRAN NB-440/441.

i NOTEAll empty slots in a partially equipped shelf must be closed with adequate dummy boardcassettes, so that the air flow inside the rack will not be affected.Dummy board casettes are available with the dimensions 295 x 20 mm, 295 x 40 mmand 295 x 60 mm (H x W).



2.4.1 Rack LayoutThe rack allows a minimal configuration with 1 TRX and can be equipped with up to6 TRX for different cell configurations.

2.6.2 Ground and Power Supply Connections -48 V DCThe NB-440 racks has to be connected to the site specific ground system before startingthe connection of DC mains cable.

An external ground wire (16 mm2, #AWG 6 for USA, copper conductor) has to beconnected on the left or right side ground stud of the rack, which must be attached tothe ground bar on site.

Grounding of the rack must be done by 16mm2 copper wire which is connected to aground bar or a site grounding ring. In the latter case, the ring must be built using 50mm2

(or more) copper inductor.

Connect the NB-440 rack and ground system as follows:

1. Use the nearest ground bar on site.2. Ascertain the distances between the connection points of the ground system

and the ground bolt of the rack.3. Cut the cables to the required length.4. Remove the cable covering at the end to connect to the ground bolt

(length approx. 10 mm) and fix a cable lug M8.5. Connect the prepared cable end to the ground bolt.6. Tighten the nut firmly.

Fig. 2.22 Ground and DC mains connections of the NB-440

The figure above shows the recommended cabling for the power supply andground connections. The recommended cable types as shown in the figure aboveguarantees the proper function of the NB-440, equipped with up to 6 TRX.

The NB-440 will be powered by -48V DC. A 2-pole terminal block of the MSU, locatedin the top of rack, is the connection point for the DC mains wires.

An easily accessible disconnect device is incorporated into the DC mains supplywiring. To isolate the DC mains supply, a 125 A circuit breaker (medium response timeand a contact separation of at least 3 mm) must be installed in the DC distribution boxfor interruption of the -48 V conductor. If there no DC pole grounded, a two-poledisconnect device is necessary.

2.6.3 Iub-Interface - Link EquipmentThe Iub interfaces, located on the EMI Panel, provide the communication links to theneighbouring Node B stations or the controlling RNC.The Iub interfaces can be terminated with Overvoltage Protections (OVPT) whichprotects the boards inside the NB-440 against overvoltage (residual voltage < 1 kV).Two types of OVPT exist: OVPTE1CF for 75 Ω and OVPTE1J1SF for 100/120 Ω cables.If this function is not needed, the Iub interfaces will be terminated with an Iub connector.The IUBCONSFV1 is the termination for 120 Ω lines and the IUBCONCFV1 for75 Ω lines.

Depending on the different cable impedances it is recommended to:– use screened cable containing 8/10 shielded twisted pairs 0,25 mm2 for

100/120 Ω PCM lines, e.g. S-09YS(ST)CY 8x2x0.6/1.2.– use coaxial cables for 75 Ω wiring, e.g. 2YCCY 0.4/2.5 .

The maximum cable length between the Iub interface and the link equipment on sitemust not exceed 42 metres (140 feet).The cable shielding must be connected to the relevant ground pins as close as possible(in order to avoid EMC/RF interfering effects).

2.6.3.1 Iub-Interface for 100/120 Ohm Cable ImpedanceBefore starting the connection of the cables at the Iub-interface of the OVPTE1J1SFor IUBCONCSFV1, prepare the twisted pair cables as shown in the figure below.

Fig. 2.25 Preparation of twisted pair cables, 120 Ohm impedance

1. Cut the cable to the required length (1).2. Cut back the outer insulation approx.13 cm (2).3. Remove approx. 11 cm of the braided shield (3).4. Cut around the outer insulation and shift the insulation ring to the end of the braided

shield (4). Remove the foil shields and the additional plastic wires.

i NOTEUse only mesh shielded twisted pair or coaxial copper cables.

2.6.8 Connection of External Reset LineIf a problem occurs to the application software and the Node B is stuck, an operator caninitiate a remote Node B hardware-restart. The Overvoltage protection for ExternalReset Line (OERF) module is the interface to the remote reset button and is located onthe EMI-panel.

The reset will be activated by use of the remote reset button. The short circuit of theterminal clamp causes a closing of the relay contact and perform a reset of the NB-440by setting the system-restart line to ground potential (active low reset).

The reset is performed as long as the reset button is pushed. As interface connector a2 pin terminal Wago-clamp is used. For connection to the remote push button on site,a 2 wire twisted pair cable with a max. wire diameter of 0.5 mm (#AWG 28-20) will beused.

2.6.9 Antenna ConnectionsThe NB-440 has to be connected to the transmit/receive antennas. The antennaconfiguration and the required cabling are dependent on the conditions found at the site.For detailed information refer to the site-specific documentation or use the correspond-ing customer documents.

For installation and service purposes it is useful to know which hardware is connectedto which cell. The numbering, seen from the top of the antenna pole, starts at anazimuth angle of 0˚ (north) and rotates clockwise.The first existing cell whose beam centre line lies at 0˚ or more is defined ascell 0 or sector 0. The next one following in the same sense of rotation is cell 1, etc.In case of an omni cell the cell no. is 0.

2.6.10 Installation of the Tower Mounted AmplifiersThe Tower Mounted Amplifiers (TMAF or DTMAF) are the RF units (external to theNodeB rack) which provide the means to feed the overall NodeB downlink signal to oneTX/RX antenna and to amplify, with low noise figure, the overall NodeB uplink signalcoming from the same TX/RX antenna.

The TMAF / DTMAF should be placed as close to the antenna as possible.It will be supplied and supervised by the multicoupling equipment (DUAMCOF) in therack it is connected to.

The DTMAF provides two 7/16 female connectors at the bottom for the connection withthe Node B (lettered NodeB 0 and NodeB 1) and on the top both 7/16 connectors forconnecting the jumper cables to the antennas (lettered ANT 0 and ANT 1).

Each TMAF / DTMAF shall be grounded to the pole, therefore a grounding wire has tobe prepared for each device on site.The mounting plate has a screw with a locking washer attached to it and a threaded holefor connection of the grounding wire (see Fig. 2.51 and Fig. 2.53).The grounding wire cable lug must have the right size for the M8 ground screw. Thecross section of the ground wire must be not less than 16 mm2.

The other end of the grounding wire should be safely connected to a well grounded pointon the pole.

Care must be taken that the draining pipe (see Fig. 2.51 and Fig. 2.53) is pointed down-wards. The draining pipe is factory mounted. If it, for any reason, would be loosened, itshould be tightened again with a sufficient torque wrench, however not exeeding2.2 Nm.

The draining pipe must never be obstructed or covered with paint which would impedethe venting and draining of the housing.

2.6.10.1 Pole Mounting with Hose ClipsThe hose clips surrounds the pole and are fitted into the corresponding openings of themounting plate (see Fig. 2.56). This is the situation just before tightening the hose clips.

For the mounting, the following steps can generally be recommended. First connect theTMAF to the antenna feeder cable. Take into consideration that the antenna feeder oftenis very stiff and rather heavy. The position of its coaxial connectors therefore oftendetermines the position of the TMAF on the pole.

1. Open the hose clips by pressing the “button” at the end of the clip lock and thensmoothly pull out the perforated metal band.

2. Move the metal band of the hose clip gently into the openings of the mounting plate.3. Close the hose clip loosely around the pole.4. Shift the TMAF into the correct mounting position.5. Tighten the hose clip screws carefully, but do not over-tighten (see Fig. 2.57).6. Connect the TMAF first to the antenna feeder cable (NodeB) and then to the antenna

jumper cable (ANT). The tightening torque must be 25 - 30 Nm.7. Connect the grounding wire with the TMAF ground screw.

Check the tightening torque, 5 Nm.8. The use of self-vulcanising tape as an environmental protection of the connectors

is recommended.

i NOTEThe TMAF and the DTMAF can be pole-or wall mounted in vertical position only !

i NOTEPay attention to the thermal dimensional changes of the antenna feeder cables.

2.6.10.2 Wall Mounting of TMAFThe TMAF may be mounted on a wall by means of suitable screws (not suppliedwith the TMAF).

The corresponding holes in the mounting plate have a diameter of 9 mm. The properway of mounting the TMAF on a wall varies from case to case. The best method canonly be decided by the installer. Please note, however, that the wall itself probably doesnot provide adequate grounding, it may be insulated.
