PLEASE NOTE:
should it be necessary to set an attenuation greater than 15dB it is strongly recommended to
connect a fixed attenuator between donor antenna and the repeater BTS side port to avoid
BTS desensitisation due to excessive radiated up-link noise.
g) Check via the spectrum analyzer that the output signal level (MS side) is correct.
When the output signal level is correct, disconnect the spectrum analyzer.
FIGURE 11 – ‘SPECTRUM’ PANEL
If the repeater is used in stand-alone configuration, connect the cable from the service antenna to
the MS connector on the bottom of the repeater (ref. 56, FIGURE 3).
If the repeater is the head station of an optical fiber system, refer to the OPTICAL FIBER COVERAGE
SOLUTIONS technical handbook to install and set Master Unit and Remote Units.
If the repeater is part of a cascade system, refer to the IN-LINE AMPLIFIERS technical handbook to
install and set in-line amplifiers.
During operation the equipment can be managed, both in LOCAL and in REMOTE mode, via the software.
In REMOTE mode the equipment is managed via a modem link. On the repeater side the modem is
installed within the equipment management module.
If installing /removing the SIM card from the built-in modem is necessary, please refer to the following
procedure 6b (HOW TO INSTALL/REMOVE THE SIM CARD FROM THE BUILT-IN MODEM).
For details regarding the software, please refer to the software User’s manual.
4.3) ROUTINE MAINTENANCE
This equipment does not require any ORDINARY MAINTENANCE (or preventive maintenance) servicing.
