Prerequisites The hardware installation of the equipment must be complete, and it should

pass the installation check.

The input power must be available.

The power switch of the input power (such as the power box of the cabinet)

must be turned off.

Tools and Instruments

Multi-meter

Procedure

Set the POWER switch on the front panel of the IDU to O.

If the IDU 605 2B is used, you should set the ODU1 and ODU2 switches on

the front panel of the IDU to O"If the IDU 605 1A or 1B is usedyou

should set the ODU switches on the front panel of the IDU to O.


17/52


Powering On the Equipment (cont.)

Turn on the power switch on the power box (or power cabinet).

testing the voltage and polarization of the input power at the access

point (such as the output terminal of the power box on the cabinet) by

multi-meter.

When the nominal voltage of the input power is48 V, the tested

voltage should be between38.4 V and57.6 V.

When the nominal voltage of the input power is60 V, the tested

voltage should be between48 V and72 V.

Set the POWER switch on the front panel of the IDU to I.


18/52


Powering On the Equipment (cont.)

Observe the indicators on the front panel of the IDU 605. Front panelindicators should comply with the following statuses and sequences.

The PWR indicator on the front panel of the IDU 605 should be

green.

The IDU indicator on the front panel of the IDU 605 should be

green, flash green, and off. The process lasts about two minutes.

Then, the IDU indicator should be constantly on. If the green

indicator is constantly on, you can infer that no alarm is generated.

If the yellow indicator is constantly on, you can infer that a minor

alarm or a warning arises. If the red indicator is constantly on, you

can infer that a major alarm or a critical alarm arises.

If the IDU 605 2B is used, you should set the ODU1 and ODU2 switches on the

front panel of the IDU to "I".If the IDU605 1A or 1B is used you should set the

ODU switches on the front panel of the IDU to "I".

Aligning Antennascont.

Precautions

If the radio link is configured in 1+1 protection mode and one antenna is used at each end,

power off the standby ODUs at both ends before aligning the antennas. After the antennas are

aligned, power on the standby ODUs at both ends.

If the radio link is configured in 1+1 SD mode, align the antennas as follows:

Power off the standby ODUs at both ends, and align the main antennas at both ends.

Power on the standby ODU at the local end. Maintain the position of the main antenna at

the remote end, and adjust the diversity antenna at the local end.

Power on the standby ODU at the remote end. Maintain the position of the main antenna at

the local end, and adjust the diversity antenna at the remote end.

If the radio link is configured in 1+1 FD mode and two antennas are used at each end, align the

antenna as follows:

At both ends, power on the main ODUs, power off the standby ODUs, and align the main

antennas.

At both ends, power off the main ODUs, power on the standby ODUs, and align the diversity

antennas.


35/52



Procedure

1. If the distance is long (more than 2 km), first position the antennas at both ends

in a horizontal manner. If the distance is short (less than 2 km), finely adjust the

elevation angle depending on the actual situation.

2. Connect a multimeter to the RSSI port on the ODU at the local end and test the

voltage value VBNC.


36/52



3. Adjust the azimuth angle of the antenna as follows:

Maintain the position of the remote antenna.

Use the multimeter to test the VBNC, and at the local end rotate the

antenna widely in a horizontal manner. Ensure that the three peak signals

of the VBNC are scanned and the central peak signal has the maximum

voltage.

4. Adjust the elevation angle of the antenna as follows:

At each VBNC voltage peak, adjust the elevation angle so that the VBNC

changes to the maximum value within the scanned range.

Adjust the antenna until the VBNC voltage reaches the maximum value.

Tighten the local antenna. When you tighten the antenna, ensure that the

VBNC voltage maintains the maximum value.


37/52



5. Repeat Step 2 to Step 4 to adjust the remote antenna.When the remotereceived signal level (RSL) reaches the maximum value,tighten the remote

antenna.

6. Repeat Step 2 to Step 5 for two to four times and ensure that the RSL at the

local end and the RSL at the remote end reach the maximum value. Tighten

the antennas at both ends.

7. Use the multimeter to test the VBNC voltage at both ends. Obtain the current

RSL by referring to the relation curve between the VBNC of ODUs and the

RSLs at both ends. The actual RSL should meet the design requirements. The

difference between the test value and the theoretical value should be within

the range from6 dB to +3 dB.

8. Tighten all the screws of the antennas.


38/52

BER tester Web LCT

Precautions

In the IDU 605 2B, the ODUs connect to the IF jumpers on the front panel of the

IDU 605 through IF cables. The main ODU connects to the IF jumper over the

ODU2 interface, and the standby ODU connects to the IF jumper over the ODU1

interface. On the front panel of the IDU,the power switch with a silkscreen of

"ODU2" controls the power supply of the main ODU, and the power switch with a

silkscreen of "ODU1" controls the power supply of the standby ODU.


46/52


Testing the IF 1+1 Switching (cont.)

Procedure1. Connect one E1 port to the BER tester on the local equipment side.

2. At the opposite equipment side, perform hardware inloop over the E1

port. If the hardware inloop fails, perform software inloop over the E1

port by using the Web LCT.

3. Test the BER by using the BER tester. There should be no bit errors.

4. Check the working status of the board by using the Web LCT.

Select an NE from the Object Tree in the NE Explorer, and then choose

Configuration >Link Configuration.

Select IF 1+1 Protection, and then click Query. In Protection Group, the

Active Board of Device should be the active IF board .If 1+1 FD

protection or 1+1 SD protection is used, the Active Board of Channel

should also be the active IF board.


47/52


Testing the IF 1+1 Switching (cont.)

5. Power off the ODU2 on the front panel of the IDU.

6. Check the BER test result. The service should recover immediately after a transient

interruption.

7. After the switching is complete, test the BER for 5 to 10 minutes. There should be no

bit error.

8. Power on the ODU2 on the front panel of the IDU.

9. When Revertive Mode of the IF 1+1 protection is set to Revertive, test the BER byusing the BER tester again. When the WTR time expires, the test result should

indicate that the service recovers after a transient interruption. WTR Time is set to

600s by default. Test the BER depending on the actual configuration.

10. Release the loopback set in Step 2.

11. At the opposite station, repeat Step 1 to Step 10 to test the IF 1+1 switching of theopposite equipment.


48/52


Testing the 24-Hour BER

Prerequisite



BER tester Web LCT

Precautions

If the 24-hour BER cannot be tested for each HOP of the link because of

restrictions of the actual situation, choose the E1 service of the first node and

the last node to perform the test. This operation ensures that the test path

covers all the radio links.


49/52


Testing the 24-Hour BERcont. Procedure

At the opposite equipment side, extract several

typical E1 services, and perform hardware

inloopover the E1 ports. If the hardware inloop fails,

perform software inloop over the E1 port using the

Web LCT.

On the local equipment side, connect these E1

services serially at the DDF, and then access them

to the BER tester.

Perform the 24-hour BER test by using the BER

tester.

Record the test result. It should meet the design

requirements.

Release the loopback and serial connection.


50/52


Testing the 24-Hour BERcont.

Postrequisite

If the first 24-hour BER test does not meet the specified requirement, find out

the cause and rectify the fault. Perform another 24-hour BER test until the test

is successful.

If the BER exceeds the nominal value in the test for a serial connection, locate

the fault by using the dichotomizing search or other methods until each

channel passes the 24-hour BER test independently.
