Note: Problems that might have occurred in using textmenu:
1. You might be incapable of deleting the words or selection you entered by backspace key. You could
delete the words or selection by delete key or login via other telnet tools to implement your operation.
2. When you get event record, if you have no action for a long while, the information would be printed
gradually in the windows instead of output to be a file. You should operate this command in the short
period of time to avoid this situation.
3. If you login in the older version operation system such as Windows 95,98, the page would not display
correctly. This is because that telnet tools version of operation system are older to automatically adjust
screen manifest. We recommend using other telnet tools other than one in the operation system.

10.8 RSL and Link Budget
The received signal level (RSL) can be estimated using the following formula:
RSL (dBm) = Pout – FL1 + G1 + G2 – FL2 – LP
Link budget or SOM (dBm) = RSL – Sensitivity of system
where: Pout is the transmitter output power (in dBm)
FL1 is the feeder loss of the transmit side (in dBm)
G1 is the gain of the transmit antenna (in dB)
G2 is the gain of the receive antenna (in dB)
FL2 is the feeder loss of the receive side (in dB)
LP is the Path loss, defined by:
LP (dB) = 96.6 + 20 log10F + 20 log10D
where: F = Frequency in GHz (1.5, 2.4 or 5.8)
D = Distance of path in km
This link budget is very important for determining any potential problems during installation. We suggest that
link budget should be more than 20dB and then the link status would be stable and transmission would be
perfect. If you have calculated the expected RSL, you can see if it has been achieved during installation, and
troubleshoot if necessary.

10.9 Troubleshooting
10.9.1 Can Not Establish a Link
If your E1 radios can’t link each other perfectly and display no green light on IDU, please find the following
steps for troubleshooting.
Step1: Check the physical connection from IDU to antenna of both sides if any connector is loosened or
improper connected. Please refer to section 10.7 for further information.
We suggest that the cable between IDU and ODU should be the one we attached in our package.
As for the signals come from the ODU are high frequency ones, we suggest customers use low-loss
high-frequency cable such as LMR-900 to maximize the distance between two sides.
Step2: Check the Rx LED on the ODU or Rx/Tx reading on the IDU. We suggest that if the Rx reading is lower
than -60dB, then it has great possibility that you encounter RF problem. You could take following measures in
order to verify the situation.
Step2.1: There is possibility of wrong antenna angle toward each other. Please adjust your antennas to
the correct angle.
Step2.2: There is possibility of air interference. Please switch your RF channel to another available one
of both sites.
Step3: Check the configuration. Please find the following configurations are correct or not by using whether
LCD panel or telnet utility.

Step4: Please conduct loopback tests to verify if the system is broken or not by following order. Please refer to
section 5.2.3 and section 8.2.13 for detail operation. If any of the following items fails, then contact us to start
RMA procedure.
10-18
Appendices
E1 Spread Spectrum Radios
Step4.1: Perform IF loopback to check if IDU works well or not. If IF loopback is error-free, then IDU must
be ok.
Step4.2: Perform RF loopback to check if ODU works well or not. IF RF loopback is error-free, then ODU
must be ok.
Step4.3: Perform the same loopback on the other sites to check if the status of the other site.
Step5: If you have spare parts for system or antennas, try to replace equipment one by one to verify the
problem. If any of the equipments fails, then contact us to start RMA procedure.
Step6: Shorten the distance between two sites to about 500 meters or connect antenna port to each other with
physical cable and about 50 attenuation loss. This is to verify the system status in short distance. If the system
fails with this topology, then the antenna or RF cable must be defective.
Step7: Recalculate link budget by the method of section 10.8. If the link budget is lower than standard, then
please reduce the system loss or increase the gain of antenna.
10.9.2 Establish a Link but Poor Performance
If E1 radios display green light on the IDU but with lots of error occurred, please find the following steps for
troubleshooting.
Step1: Check the Rx LED on the ODU or Rx/Tx reading on the IDU. We suggest that if the Rx reading is lower
than -60dB, then it has great possibility that you encounter RF problem. You could take following measures in
order to verify the situation.
Step1.1: There is possibility of wrong antenna angel toward each other. Please adjust your antennas to
the correct angle.
Step1.2: There is possibility of air interference. Please switch your RF channel to another available one
of both sites.
Step1.3: There is possibility of poor link budget. Please reduce the system loss or increase the gain of
antenna.
Step2: Check if some loopback tests have been performed then.
Step3: Please conduct loopback tests to verify if the system is broken or not by following order. Please refer to
section 5.2.3 and section 8.2.13 for detail operation. If any of the following items fails, then contact us to start
RMA procedure.
Step3.1: Perform IF loopback to check if IDU works well or not. If IF loopback is error-free, then IDU must
be ok.
Step3.2: Perform RF loopback to check if ODU works well or not. IF RF loopback is error-free, then ODU
must be ok.
Step3.3: Perform the same loopback on the other sites to check if the status of the other site.
