INTRODUCTION 2.1. PURPOSE Cellular telephone systems transmit signals in two directions between base transceiver station (BTS) and mobile stations (MS) within the signal coverage area. If weak signal transmissions occur within the coverage area because of indoor applications, topological conditions or distance from the transmitter, extension of the transmission range can be achieved by means of an optical distribution system. Such a system contains an optical master unit and a remote unit. The number of the remote unit depends on the hardware and software configuration. The remote unit is connected to the master unit with optical links. The optical loss must be less than 10 dB inclusive optical couplers or splitters. The master unit is the connection to the base transceiver stations. The configuration of a master unit depends on the number of the remote units and the frequency range. The optical transmission uses WDM-systems with a wavelength of 1550 nm in the uplink and 1310 nm in the downlink. 2.2. THE MMR8L L SINGLE BAND REMOTE UNIT The MMR8L L is a single-band multi-operator remote unit. It is used in conjunction with a master unit in the MMR optical distribution system. This system transports the whole LMR band simultaneously providing a cost effective solution for distributing capacity from one or more base stations. The MMR8L L transports signals on the RF layer in a very inexpensive manner. This means that services from various operators can be transmitted simultaneously from a cluster of base station to a remote location over the same fibre.

INSTALLATION 4.1. MECHANICAL INSTALLATION 4.1.1. General Read the health and safety warnings in chapter 1.2 Health and Safety Warnings. 1. Do not install the unit in a way or at a place where the specifications outlined in the Environmental and Safety Specifications leaflet of the manufacturer are not met. 2. It is strongly recommended to install the unit vertically. If a different installation of the remote unit is required, please contact customer service for further information. 3. It is recommended only to use the mounting hardware delivered by the manufacturer. If different mounting hardware is used, the specifications for stationary use of the remote unit must not be exceeded. ) Note: 4. Exceeding the specified load limits may cause the loss of warranty! The unit is considerably heavy. Make sure that a suitable mounting surface is used. Ensure there is adequate manpower to handle the weight of the system. 5. Due to power dissipation, the remote unit may reach a very high temperature. Ensure sufficient airflow for ventilation. Above and below the unit a minimum distance of 300 mm to ceiling, floor, etc. has to be kept. Also observe the instructions in the individual mounting procedures. If any different or additional mounting material is used, ensure that the mounting remains as safe as the mounting designed by the manufacturer. Ensure that the static and dynamic strengths are adequate for the environmental conditions of the site. The mounting itself must not vibrate, swing or move in any way that might cause damage to the remote unit. ) Note: The remote unit is delivered with a pre-mounted front cover. This cover is of vital importance for the passive cooling of the unit. Thus, do not operate the unit without cover. ID No: 163511 Page 15 User’s Manual for Remote Unit MMR8L L 4.1.2. Wall and Pole Mounting Wall and pole mounting equipment for the unit is available. For the according mounting please refer to the mounting plan (drawing) that is part of the delivery.

General Read the health and safety warnings in chapter 1.2 Health and Safety Warnings. 1. This unit contains dangerous voltages. Loss of life, severe personal injury or property damage can be the result if the instructions contained in this manual are not followed. 2. It is compulsory to ground the unit before connecting power supply. A grounding bolt is provided on the cabinet to connect the ground bonding cable. 3. Although the remote unit is internally protected against overvoltage, it is strongly recommended to earth the antenna cables close to the remote unit’s antenna connectors for protection against atmospheric discharge. In areas with strong lightning it is strongly recommended to insert additional lightning protection. 4. If the mains connector of the remote unit is not easily accessible, a separation device in the mains circuit must be provided within easy reach. 5. Before connecting or disconnecting the mains connector at the remote unit, ensure that mains supply is disconnected. 6. Make sure that an appropriate circuit breaker and an overcurrent limiting device are connected between mains and remote unit. 7. A connection of mains supply to a power socket requires the power socket to be nearby the remote unit. 8. The remote unit might be supplied from IT mains. (The maximum nominal line to line voltage must not exceed 400VAC). 9. Incorrectly wired connections can destroy electrical and electronic components. 10. To avoid corrosion at the connectors caused by electrochemical processes, the material of the cable connectors must not cause a higher potential difference than 0.6V (see electrochemical contact series). 11. It is sufficient to tighten the N antenna connector hand-screwed. Any use of a tool (e.g. pair of pliers) might cause damage to the connector and thus lead to malfunctioning of the remote unit. 12. For unstabilized electric networks which frequently generate spikes, it is advised to use a voltage limiting device. 13. The unit complies with the surge requirement according to EN 61000-4-5 (fine protection); however, it is recommended to install an additional medium (via local supply connection) and/or coarse protection (external surge protection) depending on the individual application in order to avoid damage caused by overcurrent. 14. Observe the labels on the front panels before connecting or disconnecting any cables. ID No: 163511 Page 17 User’s Manual for Remote Unit MMR8L L 4.2.2. Connections Cable gland (e.g. external alarms cable) N-connector mobile / antenna for Mains connector LED Optical connector figure 4-3 Connector flange 4.2.3. Grounding figure 4-4 Grounding bolt Grounding must be carried out. Connect an earth bonding cable to the grounding connection provided at the outside of the remote unit (see figure 4-3 Connector flange). Do not use the grounding connection to connect external devices. After loosening the hex nut, connect the earth bonding cable between the two washers as illustrated in figure 4-4 Grounding bolt. Then, fasten all parts again with the hex nut. Page 18 M0106ASB.doc 4 Installation 4.2.4. Power Connection Before connecting electrical power to the units, the system must be grounded as described in the previous chapter. Mains power must be connected at the mains connector of the unit (see figure 4-3 Connector flange). The power supply plug is part of the delivery. The correct wiring of the power supply plug is as follows: G1055Z0 figure 4-5 AC mains plug G1055Z0 figure 4-6 DC mains plug For the AC power supply connection, a minimum cross section of 1.5 mm2 is required and for the DC power supply connection, a minimum cross section of 2.5 mm2 is required. Each wire must observe the applicable national regulations regarding loop impedance, voltage drop, and methods of installation. Make sure to connect the correct voltage to the unit. ) Note: Do not connect or disconnect the power cord at the mains connector while power is on. Turn off mains* power before connecting the power cord at the remote unit, then, engage mains again. * Mains power must be interrupted with an external mains breaker. For the mains breaker, observe the following recommendation: 120 Volt / 20 Amp max. or 240 Volt / 16 Amp, single-phase, 50/60 Hz AC service is needed, i.e. the external AC breaker should be 20 Amps max. for 120-Volt service or 16 Amps for 240-Volt service. For the DC power supply, observe the local regulations of the DC service provider. ID No: 163511 Page 19 User’s Manual for Remote Unit MMR8L L 4.2.5. Connection of the Antenna Cables The remote unit has an N-type antenna connector or can be delivered with a 7/16 adapter. For its location please refer to figure 4-3 Connector flange. For mounting the cable connectors, it is recommended to refer to the corresponding documentation of the connector manufacturer. The bending radius of the antenna cables must remain within the given specifications. For the selection of cable and antenna it should be considered that a cable with higher loss is less expensive but on the other hand it impairs performance. It is sufficient to tighten the N-type (or 7/16) antenna connectors handtight. The use of a tool (like pliers) may cause damage to the connector and, therefore, lead to a malfunctioning of the remote unit. 4.2.6. Optical Fibre Cable Connection In case of a backbone structure it has to be guaranteed that there is a minimum wavelength difference of 20 nm. This will be guaranteed by using four different optical interfaces with four different wavelengths according to ITU grid. Thus, there are also four different remote units. In one optical backbone, each type of unit can only be used once! Rules for optical fibre connection Optical signals are transmitted by use of optical fibres. When connecting these fibres observe the following instructions. ) Note: Care should be taken when connecting and disconnecting fibre optic cables. Scratches and dust significantly affect system performance and may permanently damage the connector. Always use protective caps on fibre optic connectors not in use. In general optical fibres do not need special protective measures. However, protection against environmental influences e.g. rodents and humidity must be considered. The optical fibre is a single mode fibre. Type is E9/125µm with the following minimum requirements. Attenuation: <0.36 dB/km @ 1310 nm Dispersion: <3.5 ps/nm km @ 1310 nm Page 20 <0.26 dB/km @ 1550 nm <18.0 ps/nm km @ 1550 nm M0106ASB.doc 4 Installation The specified bending radius of the optical fibres must not be exceeded. The pigtails for the connection between mini master and remote unit must have a sufficient length. A protection for the feeding into units must be given. For MMR8L L the system attenuation of the optical fibres, including the connectors, must not exceed 10 dB. System attenuation and attenuation of optical components must be determined. This can be achieved by measuring attenuation and reflection with an appropriate measuring instrument. For pigtails, a total value of < 0.4 dB (measured to a reference plug) can be assumed due to the dead zone of the reflectometer. These measurements must be made with a sufficient length of optical fibre, at the in- and output of the device which has to be measured. Fibre cable connectors have to be of the same type (E2000APC) as the connectors used for the unit. The fibre optic cables are connected to the optical transceiver. ) Note: Angled connectors are not compatible with straight optical connectors; non-compatibility of connectors will result in permanent damage to both connectors. Before connecting the fibre cables, follow the procedure below to ensure optimized performance. It is important that these procedures are carried out with care: ¾ Remove fibre optic protective caps. ¾ Do not bend the fibre optic cable in a tight radius (< 4 cm) as this may cause cable damage and interrupt transmission. ¾ Using high-grade alcohol and lint-free cotton cleaning swabs, clean the end of the fibre optic cable that will be inserted in the optical connectors on the donor interface box. ¾ Blow out the laser receptacle with clean and dry compressed air to remove any particulate matter. ¾ Connect the fibre optic cables by inserting the cable end into the laser receptacle and aligning the key (on the cable end) with the keyed slot. ¾ Do not use any index matching gels or fluids of any kind in these connectors. Gels are intended for laboratory use and attract dirt in the field. ID No: 163511 Page 21 User’s Manual for Remote Unit MMR8L L 4.2.6.1. Protective Plug Connection: A protective plug is provided for the connection of the fibre-optic cables. figure 4-7 Protective plug assembly ) Note: Page 22 Only high-quality connectors must be used for this type of plug.

In case of an alarm they are high active (5V). They can be used to monitor alarms with an external alarm indicator. Each alarm output can be set individually to any alarm at the Remote Unit. For details please refer to the according chapter in the software manual of the Master Unit. ) Note: The manufacturer/ supplier of this system accepts no liability for damage caused by equipment connected to external outputs or by effects from such equipment. With the external alarm inputs, it is possible to monitor the status of connected devices, e.g. a UPS, via software. All alarm inputs are normally high (5V) without connection. The device to be monitored must be connected so that the alarm contacts (contact on the right is always GND) will be closed in case of an alarm (I max = 8 mA). The alarm inputs are potential-free with common ground. For the location of the external alarm inputs and outputs refer to figure 6-1 Connecting board. Settings have to be done via the MMR Master Controller and are described in the according software documentation. figure 6-1 Connecting board ID No: 163511 Page 31 User’s Manual for Remote Unit MMR8L L 6.6. TROUBLESHOOTING The status of the remote unit can be checked via the MMR Master Unit (for details please refer to the software manual of the MMR Master Controller). Locally, the status can be checked at the LED, see chapter 6.4 LED Alarms. Page 32 M0106ASB.doc 7 Maintenance 7. MAINTENANCE 7.1. MAINTENANCE Read the health and safety warnings in chapter 1.2 Health and Safety Warnings. ) Note: The remote unit does not require preventative maintenance measures. Maintenance of the MMR8L L should be performed on a FRU (Field Replaceable Unit) basis only. Do not damage the warranty labels on the components, as this voids the warranty. The spare parts list contains only units that can be replaced without tuning or soldering work. ) Note: Defect parts should only be replaced by original parts from the supplier. All interventions inside the housing are at one’s own risk. ) Note: During maintenance ensure that the unit has been disconnected from mains. To open the cabinet of the MMR8L L, observe the instructions in chapter 4.1.1 General. ) Note: Before disconnecting any cables, label any unlabeled cables to ensure correct reconnection. To replace an FRU, use the appropriate tools. Replacement tools may be ordered from the supplier. All screws have a right-hand thread, turn the tool clockwise for tightening and anti-clockwise for loosening. SMA connectors have a specified torque of 100 Ncm. Use an appropriate tool to fasten and unfasten these connectors. Do not over-tighten the connectors or screws. The table below shows various screws with their respective torques.
