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 several Remote Units. The number of the Remote Units depends on the hardware and software configuration. The Remote Units are 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. WDM (Wave Division Multiplex) filters are integrated in the optical modules. For the UL, a wavelength within 1540 nm 1562 nm is used. For the DL, a wavelength of 1310 20 nm is used. The maximum output power for the UL and DL is 5.7 mW. 2.2. THE ION-M7P (INTELLIGENT OPTICAL NETWORK; MMR) The fibre-optic distribution system is designed for LTE 700 MHz services. Each fibre is able to operate services of up to four providers. One Master Unit can operate up to 124 Remote Units. losses and a An auto-levelling comprehensive supervision concept are implemented. Auto-levelling in the DL works with optical power measurement, in the UL a 10.7 MHz signal is used for measuring the optical loss. The Remote Unit ION-M7P is connected to a central Master Unit via optical fibre lines. Specific customer designs for lamp pole or wall mounting are available. Thus, the system provides many advantages in view of easy site acquisition. for compensating different function fibre 2.3. COMPONENTS OF THE ION-M7P REMOTE UNIT 2.3.1. Fan-Protection Kit In order to protect the fan unit (e.g. against rain), a protective cover to be mounted over the air inlet is delivered with the unit. For more details see chapter 3.1.4 Mounting of Fan Protection. Mounting of the fan-protection kit is only mandatory for outdoor applications, however, not mandatory for indoor applications. 2.3.2. Accessories For the accessories available for the Remote Unit, e.g. overcoat housing, connecting box or iso-trafo kit, a separate manual is available. Page 14 MF0143A8A.doc 3. COMMISSIONING 3.1. MECHANICAL INSTALLATION 3.1.1. 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 supplier are not met. 2. It is recommended only to use the mounting hardware delivered by the supplier. If different mounting hardware is used, the specifications for stationary use of the Remote Unit must not be exceeded. Note: Exceeding the specified load limits may cause the loss of warranty!
3. 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. 4. Due to power dissipation, the Remote Unit may reach a very high temperature. Ensure sufficient airflow for ventilation as specified in the individual mounting procedures. 5. When connecting and mounting the cables (RF, optical, mains, ...) ensure no water can penetrate into the unit through these cables. 6. Also observe all additional rules or restrictions regarding mounting that depend on the type of Remote Unit. For details refer to chapter 7.2.2 Mechanical Specification. Install the unit vertically with the fan unit at the top. A maximum tilt angle of 25 from a vertical position must be kept, as in the following illustrations:
7. A spacing of 40 mm (1.58 inch) around the unit is required. 8. To ensure sufficient airflow when mounting the unit in enclosed spaces, two lid openings (one for the air inlet and the other for the air outlet) have to be provided. Do not block these air inlets and outlets when mounting the Remote Unit. The size of each opening must equal at least 12 x 12 cm (144 cm2). Make sure, too, there is no thermal short circuit between the air inlet and air outlet. 3.1.2. Wall-Mounting Procedure Check the suitability of the wall-mounting kit and the wall.

General Read the health and safety warnings in chapter 1.2. 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. 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 over-voltage, it is strongly recommended to earth the antenna cables close to the antenna connectors of the Remote Unit for protection against atmospheric discharge. In areas with strong lightning it is highly recommended to insert additional lightning protection. 4. If the mains connector of the Remote Unit is not easily accessible, a disconnect 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 over-current 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. Incorrectly wired connections can destroy electrical and electronic components. 9. To avoid corrosion at the connectors caused by electrochemical processes, the material of the cable connectors must not cause a higher potential difference than 0.6 V (see electrochemical contact series). 10. Use an appropriate torque wrench for the coupling torque of N-type connectors
(2 N-m / 20 in lb), with 13/16 in opening to tighten the N-type antenna connectors. For example, use torque wrench of item no. 244379 available from the Andrew e-
catalog. Do NOT use your hands or any other tool (e.g. a pair of pliers)! This might cause damage to the connector and lead to a malfunction of the Remote Unit. 11. Use a voltage limiting device for unstabilized electric networks that frequently generate spikes. Page 20 MF0143A8A.doc 12. 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. 13. Observe the labels on the front panels before connecting or disconnecting any cables. 3.2.2.

Then, fasten all parts again with the hex nut. Page 22 MF0143A8A.doc 3.3. CONNECTION OF THE ANTENNA CABLES The Remote Unit has 7/16-type antenna connectors. For its location please refer to chapter 3.2.2 Connections. 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, on the one hand, a cable with higher loss is less expensive but, on the other hand, it impairs performance. Use an appropriate torque wrench for the coupling torque of N-type connectors (2 N-m / 20 in lb), with 13/16 in opening to tighten the N-type antenna connectors. For example, use torque wrench of item no. 244379 available from the Andrew e-catalog. Do NOT use your hands or any other tool (e.g. a pair of pliers)! This might cause damage to the connector and lead to a malfunction of the Remote Unit. To minimize passive inter-modulation (PIM) distortion, attention has to be paid to the physical condition of the connector junctions. Do not use connectors that show signs of corrosion on the metal surface. Prevent the ingress of water into the connector. Attach and torque the connectors properly. 3.4. 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 chapter 3.2.2 Connections). The power supply plug is part of the delivery. The correct wiring of the power supply plug is as follows:
figure 3-9 AC mains plug figure 3-10 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 interruptible 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. Page 24 MF0143A8A.doc 3.5. OPTICAL-FIBER-CABLE CONNECTION - RULES Main optical system parameters:

exceeded. The specified bending radius ( < 4 cm) of the optical fibers must not be The pigtails for the connection between Master Unit and Remote Unit must have a sufficient length. A protection for the feeding into units must be given. The system attenuation of the optical fibers, 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 fiber, at the input and output of the device which has to be measured. Fiber-System Installation:
Fiber-cable connectors have to be of the same type (E2000APC8) as the connectors used for the unit. The fiber-optic cables are connected to the optical transceiver. Angled connectors are not compatible with straight optical connectors;
non-compatibility of connectors will result in permanent damage to both connectors. Before connecting the fiber cables, follow the procedure below to ensure optimized performance. It is important for these procedures to be carried out with care:
Do not bend the fiber-optic cable in a tight radius (< 4 cm) as this may cause cable damage and interrupt transmission. Remove fiber-optic protective caps. Using high-grade alcohol and lint-free cotton cleaning swabs, clean the end of the fiber-optic cable that will be inserted in the optical connectors on the donor interface box. Use a fiber end-face inspection tool to scan both, the class fiber and its surrounding area. Check for dirt on the cladding, chips/pits, dirt on the ferrule, and scratches. Connect the fiber-optic cables by inserting the cable end into the laser receptacle and aligning the key (on the cable end) with the keyed slot. 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. Note:
Care should be taken when connecting and disconnecting fiber-
optic cables - use the connector housing to plug or unplug a fiber. Scratches and dust significantly affect system performance and may permanently damage the connector. Always use protective caps on fiber-optic connectors not in use. Cleaning Procedure for Fiber-Optical Components:
Any contamination in the fiber connection results in additional optical transmission loss which could cause whole system failure. It is thus recommended that every fiber connector be inspected and cleaned prior to mating. The goal is to eliminate any dust or contamination and to provide a clean environment for the fiber-optic connection. When you clean fiber components, always complete the following steps carefully:
1. Turn off the ION system (laser sources) before you inspect fiber connectors. Never look into a fiber while the system lasers are on!
2. Check the connectors or adapters with a fiberscope before cleaning. 3. If the connector is dirty, clean it with a lint-free wipe (dry cleaning). 4. Inspect the connector. 5. If the connector is still dirty, repeat the dry cleaning technique. 6. Inspect the connector. 7.

4. ALARMS 4.1. BITe AND ALARMS The Built-In Test (BITe) concept comprises the monitoring of the power supplies, the power amplifiers and the optical interface. All alarms occurring can be checked via software at the Master Unit. 4.2. HANDLING OF ALARMS A message is transmitted to the Master Unit when the software acknowledges a valid alarm. A new alarm message will not be repeated if the reason for the alarm is cleared or if the alarm continues. A new alarm message will be generated if the alarm is interrupted for at least five seconds after acknowledgement. 4.3. ALARM STATUS Refer to the corresponding software documentation of the Master Unit for details. Page 34 MF0143A8A.doc 4.4. STATUS LED ALARMS For local supervision, a status LED on the connector flange of the remote unit gives an indication of possible reasons for alarms. This table shows possible on-site measures that could be checked before referring to the master unit alarm list.

EXTERNAL ALARM INPUTS AND OUTPUTS G1038Z0 G1038Z0 figure 4-1 Flange connector, 5 poles figure 4-2 Flange connector, 7 poles The alarm outputs (open collector output 5 V / 1 mA) are normally low. In case of an alarm they are high active (5 V). They can be used to monitor alarms with an external alarm indicator. The +28 V pin (for its location see figure 4-2 Flange connector, 7 poles) is protected by a 500 mA thermoswitch. In case of exceeding this current between PIN 7 and GND and/or in case of a failure of the VSWR module, the thermoswitch turns into a high-resistive status. In this case no fuse needs to be replaced. Just wait a few minutes until the thermoswitch reaches the normal operating temperature again. 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. As accessory equipment the alarm kit is available to connect external devices to the external alarm inputs and outputs (for ID No see section 6.3 Spare Parts). Page 36 MF0143A8A.doc 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 (5 V) without connection. The polarity (high/ low) can be set via the software at the Master Unit (for details please see according software manual). The device to be monitored must be connected so that the alarm contacts will be closed in case of an alarm (I max = 8 mA). The alarm inputs are potential-free with common ground. Subminiature circular connectors series 712 with five and seven contacts, which are contained in the alarm kit, can be ordered directly from the Binder Connector Group, the manufacturer, or indirectly from Andrew Solutions (for ID No of the alarm kit see section 6.3 Spare Parts).

TROUBLESHOOTING The status of the Remote Unit can be checked via the Master Unit (for details please refer to the software manual of the Master Controller). Locally, the status can be checked at the LED, see chapter 3.2.2 Connections. 5. MAINTENANCE 5.1. GENERAL Read the health and safety warnings in chapter 1.2 Health and Safety Warnings. Note:
The Remote Unit does not require preventative maintenance measures. To prevent malfunctions of the cooling system due to dirt or pollution, it is recommended to clean the heat sink at regular intervals. These cleaning intervals depend mainly on the location of the Remote Unit and the corresponding degree of pollution. Note:
Maintenance of the ION-M7P should be performed by replacing only components that are contained in this chapter. In order to maintain warranty, take care not to damage unintentionally the seals on the modules. The spare parts list, consequently, contains only units which can be replaced without tuning or soldering work. Note: When sending back the unit, use an appropriate packaging, see chapter 6.2.3 Environmental and Safety Specifications. We strongly recommend using the original packaging!
Defect parts should only be replaced by original parts from the supplier. All interventions inside the housing are at ones own risk.
