BRITECELL System Manual MN010-04 June 2003 Page 36 of 78 The company has a policy of continuous product development and improvement and we therefore reserve the right to vary any information quoted without prior notice. 22. Introduction This section describes the TPR family (19” Sub rack). The TPR is part of the Britecell system and host all plug-in modules such as TFL-card, TLC splitter/combiner, TFL-BSI Base Station Interface and control modules. A TPR sub-rack, when fully equipped, can support up to 6 TFL Local Units, one 2- way splitter-combiner, two 3-way splitter-combiners, one Base Station Interface, and one control module. Therefore this complete configuration supports up to 24 TFA Remote Units and up to 48 antennas. 23. Part description Fig. 22 TPR912 24. Warnings Local interfaces may not be placed next to each other; one 7te module is always required between them. TFL local interface cards can only be fitted in slots 1, 3, 5, 7, 9, and 11 of the sub-rack, slot 1 being the left most one. 9 WARNING: any slot capable of accepting an TFL that is unused must be fitted with a dummy plug to avoid alarms being generated (see Fig. 23) 9 WARNING: do not remove or insert any module into TPR subrack, without switching the power supply off.

Functional description The TPR subrack provides: • power supply to the active plug-in cards (12VDC); • alarm logic and relays; • mechanical housing and positioning. 25.1. Block diagram Fig. 24 – TPR block diagram 26. Alarms The TPR sub-rack has a built-in alarm circuit: any fault in TFL or TFA causes a contact relay close or open.

Installation and cabling 27.1. Location The TPR sub-rack should be placed as near as possible the BTS or the RF repeater. The sub-rack location should be easy to reach by the users in order to allow alarm monitoring. 9 WARNING! do not close the air circulation subrack grids (top and bottom) with panels or obstacles. 9 If the subrack mounting location does not have a good air circulation, leave at least one unit (1HE) free between subracks. 27.2. Power supply The connection to the mains has to be carried out following all the necessary precautions, including the following: • in accordance with diligence rules (ex. CEI rules, IEC rules, etc.); • in accordance with the rules for the safety against direct or indirect contacts; • in accordance with the rules for the safety against over current (short circuit, overloading); • in accordance with the rules for the safety against the over tension; • the connection is to be carried out by properly trained technicians. 27.2.1. Universal mains Universal main (85-264VAC, 50/60Hz) apply to TPR912 model only. Mains connector is placed on the back …

Functional description 17.1. Block diagram Fig. 15 – TFA block diagram Note 1: not present in UHF TDD version 17.2. Down link operation In the downlink the TFA fulfils the following operations: O/E Conversion: the optical signal is demodulated through an opto-electronic device (p-i-n photodiode). Amplification & Filtering: amplification is required to boost the downlink signal after is converted from light back to RF. Maintaining a good signal-to-noise ratio is critical for this operation; part of the amplification process automatically takes into account the variable loss introduced by the optical fibre. A clean-up filter is used after the amplification process to limit transmission to the downlink band and to reduce spurious emissions in the uplink band where they would interfere with the signal coming from the mobile. Duplexing: the RF signal enters a duplexer which combines downlink and uplink on a single port which is then split and goes to two separate antenna ports.

Down link operations In down link the TFL fulfils the following operations: Power level adjustment: if the RF signal coming from the BTS has a power level which is not adequate to TFL’s characteristics, an external adjustment is required. It consists in an attenuation when BTS is connected through a coupler or through repeater (please refer to TFL-BSI). E/O Conversion: RF signal modulates the intensity of an optical carrier through an electro- optic device (laser). One laser is present on each TFL card.

SYSTEM DESCRIPTION Britecell is a low power distribution system designed to provide indoor coverage for mobile communication networks. .The whole system is based on the fiberoptic transmission of multiple RF carriers from an optical donor unit interfacing to the BTSs (TFL) and an optical remote unit located in remote sites (TFA) near an antenna. The transmission of the uplink and downlink RF signals is attained by using bi- directional fiberoptic links. Furthermore it is possible to reach and feed multiple remote antennas by distributing a number of fiberoptic links in a star configuration. The system has been designed to make use of the concept of “low power distributed antenna system” (DAS). The premise of the DAS system is to achieve good link quality through the use of many lower power radiating points (fed by TFAs). The advantage of this system is lower costs and higher reliability. This is possible because high power amplifiers are both costly and less reliable than low power devises. Britecell is very simply and including a built-in AGC. As such it requires a minimum design, installation and set-up effort, in contrast with a comparable active cable systems, which require considerable uplink and downlink design and optimisation. The system.

Functional description The basic system blocks are the fiber donor unit TFL (Local Unit) and the fiber remote unit TFA (Remote Unit). They are connected in both directions (uplink and downlink) through single mode optical fibre. The system has a built-in Automatic Gain Control (AGC), which automatically adjust the up link and down link gain in order to compensate for optical link loss 1 . This allows the downlink transmit power and the up link sensitivity to be virtually independent on fibre length and on the number of splices or optical connectors present along the fibre link. Each Local unit can support and constantly monitor up to 4 remote units. Moreover up to 6 central units can be housed, together with power supply, in the same subrack 19”. The TFA feeds up to two coverage antennas. In this way it is possible to set up a network of 24 transceivers and up to 48 coverage antennae (see Fig.2). The connection between the BTS and Britecell system can either be direct or, through a repeater. In Fig. 1, a typical direct connection to BTS is showed for a dual band system. The building blocks of the combining network are: • two/three way combiners and splitters (TLC2502/3); • cross-band couplers (TLC2501); • variable attenuators (TFL-BSI). The combining network has to be carefully designed in order to optimise the connection to the BTS and the system performances. 1 provided that the specified limits are not exceeded (please refer to datasheets)

Tune-up Procedure Step 1: Connect the BriteCell donor unit to the BriteCell remote unit using single mode fiber Step 2: Connect power to both units. Step 3: Input a TX test signal into the donor unit port (N-connector) Step 4: Measure the output power at one of the remote unit ports. This signal will be +7dB gain from the donor. Increase the gain until the spurs are above -13dBm Step 5: Input an RX test signal into the remote unit port. Step 6: Measure the output power at the donor unit port (N-connector). This signal will be +17dB gain from the remote unit. It is a good rule when working with the fibre optic components, to always have available the appropriate screw covers for closure of the optic connectors that are not connected. The intrinsic delicateness of an optic connection must be highlighted. A minimum layer of dust causes a notable increase of the insertion loss, therefore. ÿ Always close the optic connectors that are not connected, with the appropriate screw covers. ÿ Always use compressed gas to remove any deposits in the receptacles before closing them. ÿ Use the appropriate cloths to clean the connectors. ÿ Do not allow the male connector to come into contact with skin or oily surfaces. ÿ Should it be necessary to clean the optic connector, only use pure alcohol.
