Commissioning Tasks Observation
1. On-line and Inquiry status
z Activate the OMT Main window. The system Initialization will
completed in about 2 minutes.
z Click “Connect” button to enquire the repeater’s status. Proceed if
there is no alarm; else check the failure and attend to the alarm.
2. Set Channel No. z Keep RF switch ON and set the channel number of the repeater’s
operating frequency.
3. Adjust Downlink Output
Power and align donor
antenna
z Observe DL input power from measured value. Align the direction of
donor antenna until the DL input power reading is maximized.
z Note: To ensure that the measured DL input power is accurate, one
should set the DL ATT to “0” before performing the check.
4. Configure [Equipment ID] z Go to [Properties Info] and set [Equipment ID].
5. Comm. Config
z Enable the power supply by selecting “On” in [RF] -> [Switch]; go to
[Properties Info.] -> [Comm. Config.] and set OMC Phones No. , the
service No. of SMSC, Report Mode.
6. Select Monitoring
Parameters
z Select the equipment controlled and monitored parameters.
z If the external devices are connected to the equipment for
management, please enable in the [External Alarm Info.] Interface.
7. Test coverage area field
intensity and adjust
service antenna.
z Use test-handset to verify field intensity within the coverage area. If
needed, realign the service antenna to achieve the desired
coverage.
z Note: If during operation, the equipment gain could not be set to
maximum or the output power is not high enough due to insufficient
donor and service antennas isolation, then the antennas’ position
should be changed to increase isolation. If the output power is too
high and ALC is activated, then adjust the DL ATT to achieve
optimal DL Gain.
8. Verify UL gain and ensure
test call produces good
voice quality and there is
no interfering BTS
z Adjust UL gain and perform test calls. Typically, the UL gain is set
around 5dB less than DL gain. Perform test calls in the coverage
area while adjusting UL gain if required.
z Note: If the repeater is near the BTS and the test call performance
is poor, this may be due to UL noise interference to the BTS. Users
can calculate and determine if the repeater UL noise will interfere
with the BTS.
z Verify again that there is no unacceptable interference to BTS.
