o
Optical link status: each indicator shows optical link status between digital
master and each remote unit. Clicking on “REMOTE LINK n” detailed monitoring
data of each optical link can be viewed: voltage, current and temperature of
each optical module, transmitted and received optical power, and alarms related
to digital data recovery system. If Expansion Unit is used to increase number of
remote units a new frame appea
rs with “EXPANSOR LINK n” title, showing link
status (between Digital Master and Expansion Unit). Data of two optical modules
involved in each link are shown: master unit side (or expansion unit side) and
remote unit side.

Remote frame: shows configuration and monitoring information of each remote unit. The
frame is divided in the following sections:
o
Uplink filtering: this section shows equivalent parameters of downlink filtering of
master unit.
Parameter Range Description
Frequency UL band
Uplink frequency channels. These frequencies
are derived automatically from downlink
frequencies, taking into account frequency
separation between DL and UL bands
Channel enable Enabled / disabled Each of 12 channels can be enabled/disabled
Bw Filter
90KHz / 45KHz /
30KHz / 20KHz /
15KHz
Bandwidth of channels filter can be
independently adjusted (if filtering is enabled)
Fine Gain Adjust -5 to +5dB
If filtering is enabled, gain of each channel can
be fine adjusted
Power indicator ---
Level of each channel, measured according to
its bandwidth filter, is shown in dBm units. Led
indicator shows if levels exceeds squelch
threshold (green) or not (yellow).
AGC ---
Show gain reduction to prevent overloading in
AGC per channel
Squelch enable
control
Enabled / disabled
Enabling this control, repeater does not transmit
in each channel if RF input power do not exceed
the threshold level configured according to next
row
Squelch threshold
control
-110dBm to -70dBm
If squelch is enabled, input levels below this
threshold are not transmitted.
