2. Introduction 2. 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.
3. Functional Description The combination of these units gives maximum flexibility while providing a scalable solution. The system is optimized for LTE, WCDMA, and CDMA signals in the 700 MHz and 1700/2100 MHz bands. Furthermore it is provisioned for future modulation schemes and frequency bands. The ION can be easily set-up and supervised from a graphical user interface (GUI). Remote units are commissioned through the use of built-in test equipment.
4. Commissioning 4. Commissioning Read and observe the health, safety, and property damage warnings as well as the description carefully to avoid mistakes and proceed step-by-step as described. Attention: Do not operate the Remote Unit without terminating the antenna connectors. The antenna connectors may be terminated by connecting them to their respective antennas or to a dummy load.
4. Commissioning 6. Notice: A spacing of 40 mm (1.58 inch) around the unit is required. 7. Notice: 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) must be provided. Do not block these air inlets and outlets when mounting the Remote Unit. The size of each opening must equal at least 16 x 16 cm (>250 cm2). Ensure that there is no thermal short circuit between the air inlet and air outlet.
4. Commissioning 4.1.3. Wall-Mounting Procedure Check the suitability of the wall-mounting kit and the wall. Mark the position of the drilling holes (for measurements refer to figure 4-1 Wall mounting). Drill four holes at the marked positions and insert dowels *. Use a cap nut or lock nut to screw the four dowel screws into the dowels and put the distance tubes over the screws. Hang the mounting brackets of the Remote Unit into the screws, and fasten them immediately using the washers and nuts.
4. Commissioning 4.1.4. Pole Mounting Standard mounting hardware cannot be used to mount the Remote Unit to a pole, a column or other similar structures. Additional hardware must be used for this type of installation. Such a pole-mounting kit could include two threaded rods M8, two U-beams and mounting material like bolts and nuts. figure 4-2 Pole-mounting kit Use the screw bands to fasten the two U-beams to the pole as illustrated in figure 4-3 Pole mounting.

5. Alarms and Troubleshooting 5. Alarms and Troubleshooting All alarms occurring can be checked via software at the Master Unit to where a message is transmitted 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. Refer to the corresponding software documentation of the Master Unit for details.
6. Maintenance 6. Maintenance 6.1. General Read and observe chapter 1.2 Health and Safety. Caution: Rotating fans. Risk of injury in operation. Wear tight-fitting clothes and disconnect mains before connecting or replacing or cleaning the fan unit. Caution: The unit reaches high temperature in operation. Risk of burns by hot surface. Do not touch the unit before it has sufficiently cooled down. Note: The Remote Unit does not require preventative maintenance measures.
6. Maintenance 6.2. Replacing the Fan Unit Replacement of the fan unit is not required as a preventative measure. Only if an alarm indicates a malfunctioning of a fan must the unit be exchanged. Note: Please observe that the fan unit can only be replaced as a whole. Do not remove the fans separately. Read and observe chapter 1.2 Health and Safety as well as the instructions in section 6.1 General before starting with the replacement. 1. Switch off the Remote Unit.
