2.6 Outline of Available Functions
Local Control
This function is used when commissioning or checking booster status on site.
Booster is connected to a Laptop using the RS-232 cable. Operators can
configure, check parameters such as gain, alarm parameters etc. Refer to
OMT
U
ser’s Manual
for more details about connection and OMT operation
procedures.
Remote Monitoring
Through the wireless modem, all functions that are accessible on the local end
can also be accessed from maintenance center remotely. Alarm signals are
constantly reported to maintenance center for constant tracking of the overall
system. Refer to
OMT User
’s Manual
for more details about connection and
OMT operation procedure.
MCB
The booster is equipped with MCB (monitor and control board), which displays
booster operating and various alarm status. At the mean time, the UL and DL
attenuation can be adjusted to make booster to perform its best via the switch
on this board
Detailed alarm of the booster can be viewed on the front panel, please refer to
Section 5: Maintenance
for in-depth details of each individual alarm condition
and their solution.
31dB Manual Gain Control
During installation, please attenuate the booster
’s DL & UL gain (using the OMT
software or via the switch on MCB), taking into account the path loss value and
isolation issue to avoid interference towards the BTS and to optimize coverage
region.
31dB AGC
The 31dB AGC is used to maintain steady output power even when the
source signal fluctuates. It also can be used as an index to evaluate the
amplifier. This function effectively prevents the equipment from entering into
saturated state and thereby avoids signal distortion and call drops in the
coverage area.
