2. FUNCTIONAL DESCRIPTION 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.
The ION-M7P/7P/85P/19P is available in single (SISO) or multi-channel (MIMO) configuration supporting 700 MHz, LTE, 850 MHz, and 1900 MHz in parallel. It has been specifically tested and optimized for LTE, OFDM, CDMA, and WCDMA signals. 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 autoleveling function compensates for the optical link loss making installation easy and quick.

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 In alarm condition, an alarm message is sent to the Master Controller. If the reason for the alarm is cleared, the alarm will disappear. Otherwise, i.e. if the alarm continues, a new alarm message will not be repeated.
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. Status LED Indication Green Orange Red Status LED off Alarms Possible on-site measures No alarm Status ok Door alarm Close the door (RUs with door). Alarms not directly related to RU: External alarms Check externally connected devices.
4.5. EXTERNAL ALARM INPUTS AND OUTPUTS G1038Z0 figure 4-1 Flange connector, 5 poles G1038Z0 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.
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.
5. MAINTENANCE 5.1. GENERAL Read the health and safety warnings in section 1.2 Health and Safety Warnings. Note: The Remote Unit does not require preventative maintenance measures. Note: 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.
5.2. 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! Note: NEVER blow out the fan unit with compressed air! This would cause permanent damage to the unit. Read the health and safety warnings in section 1.2 as well as the instructions in section 5.
5.3. CLEANING THE HEAT SINK To avoid a malfunctioning of the Remote Unit, the heat sink should be cleaned in case of pollution. In order to prevent any damage, proceed as explained in the following. Note: Read the health and safety warnings in section 1.2 Health and Safety Warnings as well as the instructions in section 5.1 General before starting with the replacement procedure. Then, proceed as follows: 1. Switch off the Remote Unit.
