In accordance with IEC215 / EN60215, adjustment, maintenance and repair of the exposed equipment shall be carried out only by qualified personnel, who are aware of the hazards involved. The minimum qualifications are established in the standard. Final installation of the systems must fulfil the EMF emission levels, as requested by regulations in force (recommendation n. 1999/519/EC). WARNING: Installation Notes Modular equipment, intended to be housed insidea rack cabinet, must be installed within a protected access area only. This area must be opportunely protected by security system that will exclude the entry, even if accidental, to not authorized and trained personnel. Alternatively, the cabinet, in which the equipment is housed, must be closed on all sides, to allow the access to internal parts to authorized personnel only 1.2 AC Power supply When working on the equipment always make sure that the equipment is not connected to the mains supply. Before power up always make sure that the equipment is connected to earth by using the equipment grounding bolt. If it is necessary to fit an AC power supply plug to power cable, the User must observe the following colour codes: LIVE terminal to BROWN lead NEUTRAL terminal to BLUE lead EARTH terminal to GREEN/YELLOW lead The User must also ensure that the protective earth wire would be the last to break, should the cable be subject to excessive strain. 1.3 Safety precautions For the correct and safe use of the equipment it is essential that both operation personnel and services personnel follow generally accepted safety procedures (see IEC Publications 215: "Safety measures for radio transmitting equipment" and 61010-1: "Safety requirements for electrical equipment for measurement, control, and laboratory use") in addition to the safety precautions specified in this technical handbook. Specific warnings and caution statements, where applicable, can be found throughout this technical handbook. Warning and caution statements and/or symbols are marked on the equipment where is necessary. (see also ANNEX n°1). As far as the equipment safety devices are concerned please remind that: -periodic functional check shall be carried out on protective devices; -functional check shall be carried out on protective devices, when they have operated under fault conditions; -safety devices shall not be altered or disconnected except for replacement; -safety circuit shall not be modified. SAFETI RULES ENG 1.4 Caution and warning statements Caution It's used to indicate the correct operation and maintenance, in order to prevent damage or destruction of equipment or other property. Warning of danger Used to indicate the potential hazard that requires correct procedures or practices in order to avoid personal injury. 1.5 Impaired safety protection Whenever it is likely that safe operation is impaired, the apparatus must be in-operative and secured against unintended operation. The appropriate servicing staff authority must be informed. For instance, the safety is likely to be impaired if the equipment fails to perform the prescribed measurements, or shows visible damages. 1.6 Electrostatic sensitive devices In case of electrostatic sensitive devices ( for instance all ICs and many other semiconductor devices belong to this class) it is essential to use a right protection to reduce the risk of personal injury. Careless handling, during repair, may imply life danger. When repairing, make sure that you are connected with the same potential as the ground of the equipment by means of the right devices, i.e. a GIRDLE (a wrist wrap with resistance) and a WINDING CORD to be connected to the girdle and to the relevant socket placed on the equipment. You must also keep components and tools at this potential. 1.7 Electrolytic Capacitors Non-solid electrolytic capacitors must not contain chemicals, which may be regarded as hazardous, if incorrectly handled. Caution is necessary, should the outer case be fractured. 1.8 Electric shock In case of electric shock it is recommended not to touch the person before breaking the circuit by means of the power supply switch; should it be not possible to break the circuit power supply it would be advisable to try to rescue the person by means of some insulating materials: e.g. a wood stick, a nylon cord or a suitable service made of plastics, etc. NEVER TOUCH ELECTROCUTED PEOPLE WITH YOUR HAND AS LONG AS THEIR BODIES ARE SUBJECTED TO VOLTAGE, OTHERWISE YOU TOO WOULD GET ELECTOCUTED. Call the doctor and then immediately perform the artificial respiration as described here below: SAFETI RULES ENG Lay the patient on his back with his arms parallel to his body; if the patient lies on an inclined plane, please make sure that his stomach be slightly lower than his breast. Open the patient's mouth and check if there are foreign bodies. Kneel down near the patient at the same level as his head's, put one of your hands under his head and the other one under his neck. Lift the patient's neck and let his head fall backwards the most possible. Shift your hand from the patient's neck to his chin; put your thumb between his chin and his mouth, your forefinger along his jawbone, keep your other fingers tight. By doing these operations start the self-oxygenation by means of deep breathings in standing open-mouthed. With your thumb between the patient's chin and his mouth, keep the patient's lips closed and blow into his nasal cavities. During these operations see if the patient's breast rises. If it is not so, his nose may be obstructed; in this case, by levering on his chin with your hand, open the patient's mouth, put your lips on and blow into his oral cavity. Look at the patient's breast and see if it rises. One can use this second method instead of the first one also if the patient's nose is not obstructed, provided that his nose be occluded by squeezing his nostrils with your hand after shifting it from his head. The patient's head must be kept bent backwards the most possible. Start with ten fast and deep expirations, then go on at the rhythm of twelve/fifteen expirations per minute. Continue as long as the patient has recovered consciousness, or a doctor has ascertained his death. 1.9 Burns As far as burns are concerned: Don't try to take off clothes from the burnt parts; Pour some cold water on body burnt areas and ask immediately for a doctor; Don't apply ointments or oily tinctures.

Besides providing reliable and good quality connections, telecommunication system services should cover as widest territory as possible. It is well-known that connections to users’ terminals are obtained on air by means of steady stations named radio bases, located through the whole territory so as to obtain a continuous covering through cells one next to another. That allows a great number of users to enter the system using few channels. It is important to maintain the continuity of radio-electrical coverage (and consequently, of service within each cell) in order to guarantee an acceptable level of communication. BTS Tri-cellular FIGURE 1 – SUBDIVISION OF THE TERRITORY IN CELLS Off-Air Repeaters are proposed as a valid and economical solution to optimize the cell coverage of the territory and irradiate shadow area as an alternative to solutions requiring dedicated Radio-Bases (Figure 2). MicroBTS solution Repeater solution 2Mbit radio connection BTS The repeater costs are 50% lower than with the μ BTS solution μBTS Repeater BTS Source Shadow Zone Shadow Zone FIGURE 2 – RADIO-ELECTRICAL PROBLEMS IN CELL NETWORK COVERAGE 1800MHz-1900MHz Off-Air Repeaters (OR Series) CHAPTER 3 Page 3.1 91 080 0701F – Rel.04 Off-Air Repeaters on one side receive the signals from the radio base station, amplify them and re-transmit them in the direction of the shadow area (down-link path). On the other side Off-Air Repeaters receive the signals from the mobiles (MS), amplify them and re- transmit them to the base station (up-link path). When a single Off-Air Repeater does not provide satisfactory coverage, the repeater can be used along with other equipment. Different solutions are provided: cascade systems, based on Bi-Directional Amplifiers, and optical fibre solutions, based on Remote Units. 3.1) EXAMPLE: USE IN TUNNELS The Off-Air Repeater interfaces directly with the BTS of the provider of the services to be extended, and can be used along with other equipment distributed inside the tunnels. Such equipment can be divided into two types, according to the radio-coverage system used: - Bi-directional amplifiers, for cascade systems. - Remote Units, for optical systems. The following are a few examples of general projects for radio-electric coverage in tunnels. • Tunnels with a length of less than 300 meters. In this case, one single Off-Air Repeater is sufficient. It is located at the entrance to the tunnel, equipped with an antenna which irradiates in the direction of the shadow zone (Figure 3).

Also in this case, one single Off-Air Repeater is sufficient. The repeater is located at the entrance to the tunnel and equipped with a leaky cable. This cable can be combined with a directional antenna to irradiate a portion of the area in front of the tunnel exit (Figure 4).

The signal can be enhanced in two ways: a) By an Off-Air Repeater at the entrance to the tunnel, connected to a cascade of bi-directional amplifiers inside the tunnel which re-generate the signal with amplification steps at a distance of 250mt. ÷ 400mt. from one another (Figure 5).

The DC powered repeater can be power-fed by a 48Vdc power supply source only. The AC powered repeater can be power-fed from MAINS (230Vac) or from a 48Vdc power supply source or both from MAINS and from a 48Vdc source. The presence of both power supply voltages guarantees the continuity of the coverage service even in case of failure of one source. The commutation is handled automatically by the repeater. Off-Air Repeaters are bi-directional amplifiers. The signal to be extended follows two distinct paths: the uplink path, from the mobiles to the radio base station, and the down-link path, from the radio base station towards the mobiles. Figure 7 provides a block-diagram of the 1800/1900MHz adjustable band Off-Air Repeater.

C1). The selection of the band of frequencies to be extended is handled by two band-selective modules, ref. D1 and ref. D2, which make the band-pass and frequency center programmable entities. The band of frequencies to be extended can be managed by the user by means of the management system. The signal is then amplified by the High power amplifier (ref. E1) filtered by the MS side duplexer, ref. B2,and transmitted by an antenna or a passive distribution system. A VSWR detector is equipped. The up-link path is identical to the down-link path described above. 1800MHz-1900MHz Off-Air Repeaters (OR Series) CHAPTER 3 Page 3.5 91 080 0701F – Rel.04 The 48Vdc powered repeater is equipped with a DC/DC converter, ref. F. The A.C. powered repeater is equipped also with an AC/DC converter, ref. L. The management module, ref. G, makes it possible to manage the repeater in remote mode via a built-in modem, or in local mode through the RS232 connector, available on the management module. The repeater management is performed by means of the Operation and Maintenance Terminal software, both in local mode and in remote mode (ref. Chap. 4). 3.3) ATTACHED DOCUMENTS TECHNICAL CHARACTERISTICS 1800MHz 48Vdc/230Vac ADJUSTABLE BAND OFF-AIR REPEATERS ILL DCS OFF-AIR REPEATERS (ILLUSTRATIVE DRAWINGS) Sheet 1, equipment composition and backplane access points map Sheet 2, modules access points map and external access points map TECHNICAL CHARACTERISTICS 1900MHz 48Vdc/230Vac ADJUSTABLE BAND OFF-AIR REPEATERS ILL PCS OFF-AIR REPEATERS (ILLUSTRATIVE DRAWINGS) Sheet 1, equipment composition and backplane access points map Sheet 2, modules access points map and external access points map 1800MHz-1900MHz Off-Air Repeaters (OR Series) CHAPTER 3 Page 3.6 91 080 0701F – Rel.04 ANNEX 1 TECHNICAL CHARACTERISTICS 1800MHz 48Vdc/230Vac ADJUSTABLE BAND OFF-AIR REPEATERS 1800MHz OFF-AIR 1800MHz OFF-AIR REPEATER REPEATER 48Vdc MODEL 230Vac MODEL 1710 ÷ 1785MHz TECHNICAL CHARACTERISTICS Up Link operating frequency band 1805 ÷ 1880MHz Down Link operating frequency band Number of amplified bands Programmable Bandwidth / steps From 1MHz to 16.5MHz / 10kHz step adjustable Output Power 28dBm (2 carriers) 3rd Order Intercept Point (OIP3) 57dBm Output Power at 1dB compression point 36dBm Noise Figure @ max. gain 8dB 50 ÷ 80dB / 1dB step Gain / Step Ripple into operating band ± 2dB Total processing delay Return Loss ALC threshold (default value) Spurious emissions and intermodulation products Local Control Interface 6μs 14dB 3dB over nominal output power (this value can be changed on site) < -36dBm (in the frequency band 9kHz ÷ 1GHz) < -30dBm (in the frequency band 1GHz ÷ 12.75GHz) RS232 Remote Control Interface PSTN – GSM/DCS modem -72 ÷ -36Vdc -72 ÷ -36Vdc 85÷265Vac (50-60Hz) 110W @ 48Vdc 140VA @ 230Vac Power Supply Power Consumption MTBF 50 000 hours Operating Temperature (*) -20°C up to +55°C Degree of protection provided by enclosure IP65 RF connectors 7/16 female 423x395x230mm (max. volume -
