Service ANT or LCX equipped • Cable should be installed without exterior damage. • Protect connection parts like connector with insulation tape to prevent humidity. • Install feeder to minimize environment influence. 2 Installation of Antenna for Donor • Strongly fixed for local wind velocity to prevent antenna’s direction from bending after installation 3 Power cable and RF cable arrangement • Prevent cable from damaging by crooking or stretching.
CDMA REPEATER 9. System Set Up and Inspection 9.1 Items to be checked for Opening A. Confirm AC 108 ~ 127 VAC common use power and power cable. B. Check if Donor RF input signal from exterior is at normal level. Caution※ When system operates without input signal confirmed, over-input may cause serious damage on amplifying degauss because of saturation of output. Therefore, after checking input signal level by equipment and ALC ON state(on shipment ALC ON) operate equipment. C. Put 108 ~ 127 VAC into power connector of equipment to switch ON. D. Check Alarm LED blinking state of GUI or Repeater’s front board through laptop. E. When it is judged that Down Link RF input signal from exterior is normal, switch OFF the Repeater to connect ANT feed and Service ANT to Input/Output Port of Repeater and switch ON again. Caution ※ Conclude carefully lest Down Link and Up Link Port be reversed. 9.2 Items to be check after opening A. Confirm existence of abnormality by checking the alarm LED lighting status of repeaters. B. Confirm whether the RF input/output values are normal or not by using GUI. C. Confirm the normal operation status of repeaters by measuring the characteristics, etc. of spurious waves of the repeater’s down link and up link output using a spectrum waveform analyzer by using a coupling terminal beside each input/output port of the repeater after about 10 or more minutes passes after turning on the power of repeaters. D. Optimize the electric wave environments while comparing with the status before opening about whether there is no electric wave shade region or non-communicable region by measuring the communication quality in the service region using a terminal or gauge after normal operation of the repeater.
CDMA REPEATER 9.3 Failure and Inspection 9.3.1 Inspection of Repeater On routine or emergency service of repeater the following orders should be taken to check its failure. A. Check RF input/output level and LED of repeater using Web GUI. On routine service check calling quality with terminal or measurer, or on emergency service the following should be taken even if RF input/out level of repeater on Web GUI is normal. B. Connect link harmonic analyzer to test terminal of repeater to confirm output state. C. Use Coupling port to check output value. D. Check if the output value of repeater obtained by harmonic analyzer agrees with actual out put value of repeater. E. Check input level of repeater when the output value of repeater obtained by harmonic analyzer does not agree with actual output value of repeater. F. When input level is not same as the one on installation time showing distinct difference, check antenna welding state and feeder’s installation state. G. If the output value of repeater is abnormal as comparing input level to operation gains of repeater, switch ON/OFF the repeater to check the output state with harmonic analyzer. On severe failure immediately replace with spare parts to supply normal service.
CDMA REPEATER 9.3.2 Facility Inspection On routine Inspection and service failure the following parts and items are needed to be inspected. Inspection Parts Inspection Items Remark Donor Antenna & Service Antenna Inspect the malfunction of Antenna’s welding, received signal’s intensity of donor antenna and RSSI value. Feeder, Leakage Coaxial Cable Inspect whether feeder or leakage coaxial cable may be cut or damaged. Connector, Distributor Inspect whether connector’s linking part or cable may be flooded, or whether each linking part is firmly fastened. Power Incoming Part Confirm that common terminal box for 108 ~ 127 VAC is not leaked.
