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 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.
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 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.
3.1.2. 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.
3.2. ELECTRICAL INSTALLATION 3.2.1. 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.
3.2.2. Connections AUX connector Status LED BBU connector Mains connector Connector to Substitute Unit N-antenna connectors Connectors to main unit Connectors to Redundant RU Optical connector figure 3-3 ION-M8P S, connector flange, exemplary 3.2.3. Grounding Grounding must be carried out. Connect an earth-bonding cable to the grounding connection provided at the outside of the remote unit (see chapter 3.2.2 Connections). 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 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.
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.
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.
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.
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. ** Upper insulation body Cavity B Cavity A 4. Bring the insulator into the plug.
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. *** Screw tight until gap is closed 8. Connect the plug to the optical-fibre 9. To lock the connector, push the black connector of the remote unit, again by locking ring forward.**** fitting a stamp on the plug into the groove of the connector.
