- User Interface Introduction
- Common Problems and Solutions
| No. | Problems | Possible Reasons | Solutions |
|---|---|---|---|
| 1 | Connection fail between OMT software and repeater | Incorrect software | |
| version | Update latest OMT software version | ||
| Querying locally fail | Make sure the data cable can communicate normally | ||
| Device IP address is incorrect | When connecting locally, please ensure that |
the IP address of the device itself is consistent with the IP address filled
in by the software
2| Downstream output abnormal, can’t cover the blind area| Downstream power
amplifier switch is turned off| Use software to see if it is off, and if so,
turn it on
Higher attenuation| Use software to view and adjust attenuation values
Input signal is abnormal| Use a spectrum analyzer to check whether the signal
entering the BS port is normal
Poor wiring at MS terminal| Use a spectrum analyzer to directly test the
output power of the trunk amplifier. If the output is normal but still cannot
cover the blind area, it indicates that the engineering wiring at the MS end
is incorrect
3| Upstream output abnormal, can’t cover the blind area| Poor interface or
unstable uplink signal| Check whether each interface is in good condition;
Connect the signal source to the BS port, and then use a spectrum analyzer to
test whether the uplink output is normal and stable
| | High uplink noise floor affects base station operation| Adjust uplink
gain; Confirm that the correct coupler is selected
---|---|---|---
Strong interference source nearby| Eliminate sources of interference
4| ****
Remote communication failure
| Device stops working| Return the device to normal operation
MODEM is not working properly| Use a small antenna to connect the MODEM’s
antenna externally to test whether it can communicate normally. If not,
replace it with a new MODEM
SIM card failure or arrears| Put the SIM card into the phone and see if it can
send text messages. If damaged, replace it with a qualified monitoring card
The device number setting is different from the monitoring center| The site
number, device number, and mobile phone number of the monitoring center must
be consistent with those of the trunk amplifier
The network is busy or communication failure| Wait until the network condition
improves and try again
5| Alarm| Power failure alarm|
- Check whether the power module detection wiring is in good condition
- If the power module is damaged, please replace the module
Monitoring module battery failure alarm| The backup battery voltage is low due
to bad battery or discharge, replace the backup battery or recharge the
battery
Downlink input power shortage| The threshold value is set too high, adjust the
threshold value. The input signal is too weak or there is no input signal,
check whether the source and repeater have outputs or use a coupler with a
small coupling degree
Downlink input overpower| The threshold value is set too low, adjust the
threshold value. The input signal is too strong, change the output power of
the source or repeater or use a coupler with a large coupling degree
Downlink output lack of power
| Set the threshold value high and adjust the threshold value. If the
attenuation is too large and the output lower than the threshold, adjust the
attenuation
**** Amplifier over temperature alarm| The power amplifier temperature is
higher than the threshold value. Set a higher threshold value or let the power
amplifier temperature drop below the threshold value
