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.
User’s Manual for ION-M4/8 19" The ION-M4/8 19" has been specifically designed to reduce zoning problems. The compact mechanical housing is designed to mount alongside structures in such a way that it has minimal visual impact. The ION-M can be easily set-up and supervised by a graphical user interface (GUI). An auto-levelling function compensates for the optical link loss and making installation easy and quick. The entire system can be monitored remotely by A.I.M.O.S., the Andrew OMC.

User’s Manual for ION-M4/8 19" 4.2.3. Power Connection and Grounding Mains connector Grounding bolts figure 4-3 Mains connector and grounding screw Page 28 Before connecting electrical power to the units, the system must be grounded at the grounding screw at the front side. Unscrew the grounding screw located at the front side (see illustrations above) and fasten a 4 mm2 grounding cable there.
4 Commissioning 4.3. CONNECTION OF THE ANTENNA CABLES The remote unit has N-type antenna connectors. For its location, please refer to chapter 4.2.2 Cabling and 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.
User’s Manual for ION-M4/8 19" 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.
4 Commissioning 4.6. COMMISSIONING Read the health and safety warnings in chapter 1.2 Health and Safety Warnings as well as the description carefully to avoid mistakes and proceed step by step as described! • Do not operate the remote unit without terminating the antenna connectors.
