2. INTRODUCTION 2.1. PURPOSE Cellular telephone systems transmit signals in two directions between a 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. The optical transmission uses WDM-systems with a wavelength of 1550 nm in the uplink and 1310 nm in the downlink. 2.2. THE ION-M8P S (INTELLIGENT OPTICAL NETWORK; MMR) The Andrew ION-M8P S is a multi-operator remote unit with various extension units. It is used in conjunction with a master unit in the ION optical distribution system. This system transports the entire 700 MHz public safety and 800 MHz LMR frequency bands simultaneously, providing a cost-efficient solution for distributing capacity from one or more base stations. The ION-M8P S 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 at poles or along side structures in such a way that it has a minimum visual impact. The ION-M8P S performance is available both in single or multi-band configuration supporting 700 MHz, and 800 MHz in parallel. It has been specifically tested and optimized for TDMA, CDMA2000, and WCDMA. Furthermore it is provisioned for future improvements to modulations (e.g. HSPA+, EV-DO and OFDM) and frequency bands. In addition it is backwards compatible to legacy standards such as Analog. 13 of 42
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 leveling 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:  Multi-band, multi-operator support  Reduced visual impact form factor  High, efficient 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  Easy installation and commissioning  Redundancy configuration option 2.3.

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 antenna connectors of the remote unit 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 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 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. 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 ¼-inch 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. For unstabilized electric networks which frequently generate spikes, it is advised to use a voltage limiting device. 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. 17 of 42
3.2.2. Connections 18 of 42 figure 3-3 ION-M8P S, connector flange, exemplary 3.2.3. Grounding Grounding must be carried out.

After loosening the hex nut, connect the earth-bonding cable between the two washers as illustrated in the figure above. Then, fasten all parts again with the hex nut. The PE cables must have a minimum cross section of 16mm2. 3.2.4. 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 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 3-5 AC mains plug figure 3-6 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. 19 of 42
 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. 3.3. CONNECTION OF THE ANTENNA CABLES The Main Unit has N connectors. For its location, please refer to chapter 3.2.2 Connections. However, the Combining Unit has 7/16 antenna connectors (described in separate manual). 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 inch 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. Use an appropriate torque wrench for the coupling torque (25 N-m / 19 ft lb) of 7/16-DIN connectors with 1 ¼-inch 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. 3.4. CONNECTION OF THE RF CABLES MAIN UNIT TO COMBINING UNIT To connect RF cables to Combining Unit, connect corresponding ports according to frequency as labelled. For orientation of the location of connectors please refer to the illustrations of Main Unit in chapter 3.2.2 Connections and/ or of Combining Unit in chapter 4.6 Redundancy Relay Configuration. 20 of 42
3.5. OPTICAL-FIBRE-CABLE CONNECTION - RULES 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 E9/125 µm with the following minimum requirements. Attenuation: <0.36 dB / km @ 1310 nm / <0.26 dB / km @ 1550 nm Dispersion: <3.5 ps / nm km @ 1310 nm / <18.0 ps / nm km @ 1550 nm 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 ION-M8P S, 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 input 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. 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 for these procedures to be carried out with care: 21 of 42
 Remove fibre-optic protective caps.  Do not bend the fibre-optic cable in a tight radius (< 4 cm) as this may cause cable damage and interrupt transmission.  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.  Blow out the laser receptacle with clean and dry compressed air to remove any particulate matter.  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.  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. 3.5.1. Protective Plug Connection: A protective plug is provided for the connection of the fibre-optic cables. figure 3-7 Protective-plug assembly  Note: Only high-quality connectors must be used for this type of plug. Qualified brands are Diamond or Huber & Suhner. 22 of 42
For plug assembly, observe the following instruction: 1. Pass one or two contacts through the backshell and the clamp ring. 2. Place the contact(s) on the lower insulation body by pushing the groove of the contact into the cavity. If there is only one contact, cavity A must be used. * 3. Then, mount the upper insulation body on the lower insulation body. ** 4. Bring the insulator into the plug. The narrow groove of the insulator must be fitted into the stamp of the plug. * To release the contact for disassembling, push the inner snap to the side and pull the contact out. ** To release upper and lower insulation bodies for disassembling, use a small screwdriver and carefully open the snap-connections at the left and the right side of the insulator without damaging them. 5. Fasten the insulator by screwing the backshell tight onto it. Use a spanner with opening 32 to screw the backshell tight (no gap). 6. Place the appropriate seal parts (with one groove for one contact or two grooves for two contacts) over the cable(s) and push them into the backshell. Seals with one groove No gap Cavity B Upper insulation body Cavity A 23 of 42
7. Bring the plastic ring over the cable(s), push it into the backshell and compress the seals and plastic ring by screwing the clamp ring tight (no gap) using a spanner with opening 20. *** 8. Connect the plug to the optical-fibre connector of the remote unit, again by fitting a stamp on the plug into the groove of the connector. 9. To lock the connector, push the black locking ring forward.**** Screw tight until gap is closed 24 of 42 *** For disassembling, release the clamping ring and remove the seals and the plastic ring first. **** Locking mechanism: The system of locking the plug is based on a “push-pull” mechanism. The locking ring has to be pushed forward to lock the connector and pulled back to free the connection. 3.5.2. Protective-Tube Kit As additional protection for the optical fibres, this connector type can be supplemented by a special tube kit. To fasten the tube correctly, first unscrew the clamp ring (if already installed) of the original plug kit. Then, proceed according to the following instruction: Groove Push forward to lock, pull back to free connection

4. ALARMS 4.1. BITE AND ALARMS The Built-In Test concept comprises the monitoring of the power supplies, the power amplifiers and the optical interface. All occurring alarms can be checked via software at the master unit. 4.2. HANDLING OF ALARMS As soon as the software acknowledges a valid alarm, a message is transmitted to the master unit. If the reason for the alarm has been cleared or if the alarm should continue, a new alarm message will not be repeated. If there was an interruption of at least five seconds after acknowledgement, a new alarm message will be generated. 4.3. ALARM STATUS For details refer to the corresponding software documentation of the master unit. 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. The position of the status LED is illustrated in chapter 3.2.2 Connections. This table shows possible on-site measures that could be checked before referring to the master unit alarm list.

4.5. RELAY ALARM CONNECTING BOARD 4.5.1. External-Alarm Inputs and Outputs There are four alarm inputs and four alarm outputs. The alarm outputs are potential-free relay contacts. 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 (5 V) without connection. The device to be monitored must be connected so that the alarm contacts will be closed in case of an alarm (maximum switching power of 28 Vdc, 0.5 A). The location of the external-alarm inputs and outputs is illustrated in the following chapter 4.5.2 Layout and Connector Description. Settings have to be done via the ION-M Master Controller and are described in the according software documentation. Please note that at the remote unit (RU), the alarm ground of the external-alarm inputs is linked with the ground at the RU. 31 of 42
