a terrestrial line (in this case symmetric pair or coaxial cable is used)or microwave (additional equipment is therefore required)

– Submultiplexing on the Abis-interface

1.3 Standard Technical Features– Full software download capability– Full rate and half rate Traffic Channels are supported– GSM primary/extended Band ; DCS Band; PCS Band– Hybrid combiners, Duplex combiners and Filter combiners for antenna combining

available– Outstanding Rx sensitivity– 16/64 kBit signalling channels and minimised signalling load on Abis– LMT-operation with full O&M functionality at a transmission rate of 64 kBit– Modular capacity increase of sites

!The CE declaration of conformity for the product will be fulfilled if the setup and cablingis undertaken in accordance with the specification in the manual and the documentationlisted there, such as mounting instructions, cable lists etc.Where necessary, accountshould be taken of project-specific documentation.Deviations from the specifications or independent changes during setup, such as use ofcable types with lower screening values, for example, can lead to the CE requirementsbeing violatad. In such cases the CE declaration of conformity is invalidated and theresponsibility passes to the person who has caused the deviations.

serves up to 2 cells, max. 2 carrier per cell

1.5 Installation PrerequisitesIt is absolute required that the installer pays attention to the valid EMC instructions.

Lightning protection zone 1 according IEC 1312-1/DIN VDE 0185 part 103 insidethe construction room is recommended.

All other equipment on site must be CE designated and must provide interfaces forconnecting of external cables conformable to EMC instructions.

1.6 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

These are sensitive to static discharge.

Notice:– 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 packing

1.7 Installation ToolsThe correct rack installation is carried out with the aid of the following tools:– Standard toolkit for BSS-installation– Spirit-level

2 BS 20 Installation

2.1 Position in the SystemLike all other base stations the BS20 interconnects the MS via the Um interfacewith the trunk network via the Abis interface.

Fig. 2.1 Position of the BS21 within the SBS

2.2 Site RequirementsPrior to the commencement of installation, the construction of the room in which thebase transceiver station is to be housed must be complete and the room in good condi-tion and dry - heaters, if necessary, should be put up in the room.Dependend on the power consumption of the BS20, the AC mains output of thepower supply equipment must provide a connected load of 800 W / 3,5 A.

In case of wall mounting, a load-carrying capacity of 2.50 kN/m2 is required for hang upthe BS20. If floor mounting is planned, the floor load capacity must be not less than650 kp/m2. A minimum floor space of 1,50 m x 1,50 m should be provided for bothmounting variants.

The BS20 is intended to be installed in a restricted access area.– Doors and windows must already have been installed and must be lockable.– Openings in wall or ceiling of floor - if required - must be complete.– The floor coverings must have been laid.– Room lighting and wall sockets must have been installed.– Heating or air-conditioning systems should be ready for operation.– Walls and ceilings should have been painted.The room must be clean.– A minimum floor space of 1,50 m x 1,50 m should be provided.– The construction of the installation room requires the realization of

lightning protection zone 1 according IEC 1312-1/DIN VDE 0185 part 103.

To prevent subsequent accumulation of dust and dirt, the parts and equipmentunits to be installed must be unpacked outside the room (if possible).

After that it is advantageous to install the BTS, after all other installation works tocreate the required infrastructure (power supply, antenna cabling, PCM line...)are complete.

2.7.5 Abis-Interface - PCM Link TerminalThe Abis interface, located on RCAP, is terminated with the OvervoltageProtection (OVPT) which protects the LI inside the BS20 against overvoltage(residual voltage < 1 kV).Two types of OVPT are exist (for 75 Ohm or 120 Ohm cables).

Dependend on the different cable impedances is recommended to:– Use screened cable containing 8/10 shielded twisted pairs 0,25 mm2 for 120 Ohm

PCM lines, e.g. MOD-IY-2DY-FCY.– Use coaxial cables for 75 Ohm wiring, e.g. S-09YS(ST)CY 8x2x0.6/1.2.

The maximum cable length depends on the attenuation of the cable, in order to fulfilthe requirements of minimum voltage levels to be provided at Abis interface accordingto PCM standards.The cable shielding must be connected to the relevant ground pins as close as possible(in order to avoid EMC/RF interfering effects).

2.7.5.1 Abis-Interface for 120 Ohm Cable Impedance

Fig. 2.12 OVPT with terminal block (120 Ohm)

Connect the Abis-interface with twisted pair cable to the PCM link terminal as follows:– Cut the cable to the required length and cut back the outer insulation

(approx.19 cm). Remove the wire insulation (0,8 mm).– Wrap the exposed cable shield, whitch will be fixed at the stress relieving, with adhe-

sive copper foil (approx. 4 cm).– Fix the prepared cable close to the stress relieving by straps.– Insert the wires into the terminals of the OVPT.– Insert the additional wire (shielding potential) into one of the ground terminals

(e.g. no. 24).– Lead the additional wire and the uplink and downlink wires on the shortest way

(that means without sleeves) between the stress relieving and the screw terminals.– All unconnected PCM lines (4 wires per line) must be connected to one of the

ground terminals.

It is advantageous to protect the short part of the cable between stress relieving andterminal block with a shrink tube or adhesive tape.

2.10.2 Identification of Antenna Feeder CablesFor installation and service purposes it is useful to know, which hardware is connectedto which cell. The numbering, seen from the top of the antenne pole, starts at anazimuth angle of 0˚ (north) and rotates clockwise.The first existing cell which beam center line lies at 0˚ or more degree is defined ascell 0 or sector 0. The next one following in the same direction cell is cell 1 etc.In case of omni cell the cell no. is 0.

Adhesive tape in different colours will be used for identification of the antenna feedercables, which has to be connected via short jumper cables to the antenna connectors of
