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-M17HP/19HP (INTELLIGENT OPTICAL NETWORK; MMR) The ION-M17HP/19HP is a multi-band multi-operator Remote Unit with various extension options. It is used in conjunction with a master unit in the ION optical distribution system. This system transports multiple frequency bands simultaneously

(1900 MHz and 1700/2100 MHz), providing a cost-effective solution for distributing capacity from one or more base stations. The ION-M17HP/19HP transports signals on the RF layer in a very inexpensive manner. This means that multiple operators and multiple technologies are moved simultaneously from a cluster of base stations to a remote location over the same fiber. The ION optical distribution system is a cost-effective coverage solution for dense urban areas, tunnels, subway, airports, convention centers, high-rise buildings and other locations where physical structures increase path loss. It has been specifically designed to reduce zoning problems and to provide homogeneous coverage. The compact, mechanical design is specifically architected to mount inside of poles or along side structures in such a way that it has a minimal visual impact. Page 12 Manual ION-M17HP-19HP MF0143AXA.doc is available ION-M17HP/19HP The in a multi-band configuration supporting 1900 MHz and 1700/2100 MHz in parallel. It has been specifically tested and optimized for GSM, EDGE, HSPA+, OFDM, EV-DO and WCDMA. Furthermore it is provisioned for future improvements to the modulation and frequency bands. The ION is easily set-up and supervised via a graphical user interface (GUI). Remote Units can be commissioned through the use of built-in test equipment. An auto-

levelling function compensates for the optical link loss making installation easy and quick. The entire system may be monitored remotely via an Andrew OMC. This is a comprehensive management platform with SNMP protocol and X.733 standard implemented. Should a sophisticated interface not be required, the master unit can be directly connected to the alarm interface of a base station via relay alarming. Features at a glance:

Multi-band, multi-operator support Reduced visual impact form factor Efficient, high power amplifier Single fiber for multiple bands and multiple remotes Comprehensive operations and management system for configuration and alarming OMC with SNMP according to X.733 standard 3GPP TS25.143/TS25.106/ TS36.143/TS36.106 and 3GPP2C.S0051-0 compliant Easy installation and commissioning For your notes:

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 (25 N-m / 19 ft lb) of 7-16 DIN connectors with 1-1/4 in opening to tighten the 7/16-type antenna connectors. For example, use torque wrench of item no. 244377 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 Manual ION-M17HP-19HP MF0143AXA.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.

Then, fasten all parts again with the hex nut. Page 22 Manual ION-M17HP-19HP MF0143AXA.doc 3.3. CONNECTION OF THE ANTENNA CABLES The Remote Unit has 7/16-type antenna connectors. For its location please refer to section 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 (25 N-m/ 19 ft lb) of 7-16 DIN connectors with 1-1/4 in opening to tighten the 7/16-type antenna connectors. For example, use torque wrench of item no. 244377 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 section. Mains power must be connected at the power supply connector of the unit (see section 3.2.2 Connections). The power supply plug is part of the delivery. The correct wiring of the power supply plug is as follows:

PIN 2 - N PIN 1 - L PIN 3 - n.c. PIN 4 - PE figure 3-10 AC power supply plug For the AC power supply connection, a minimum cross section of 1.5 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 power supply connector while power is on. Turn off mains power * before connecting the power cord at the Remote Unit, then, engage mains power again.

* Mains power must be interruptible with an external power supply breaker. For the power supply 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. 3.5. OPTICAL-FIBRE-CABLE CONNECTION - RULES Main optical system parameters:

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. Page 24 Manual ION-M17HP-19HP MF0143AXA.doc 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. 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. Note:

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. If the connector is still dirty, clean it with 99% isopropyl alcohol (wet cleaning) followed immediately with a dry clean in order to ensure no residue is left on the endface. 8. Repeat steps 5 through 7 until endface is clean. Note: For a more detailed description please refer to:

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 the exact ID No., please refer to section 6.3 Spare Parts. 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.
