1. Connecting the Web LCT to the IDU

Connecting the Web LCT to the IDU properly is a prerequisite for future dataconfiguration and for other commissioning items.

Prerequisite

The equipment must be powered on.

Tools, Equipment, and Materials

Web LCT

Procedure

1.1 Start the laptop and log in to the operating system.

1.2 Set the IP address of the laptop.

The IP address of the laptop should meet the following requirements:

The IP address of the laptop and the IP address of the NE should be in thesame network segment (the default network segment is 129.9.0.0), and the IPaddress of the laptop is different from the IP address of the NE.

The subnet mask of the IP address of the laptop should be the same as thesubnet mask of the IP address of the NE (the default subnet mask is255.255.0.0).

The default gateway is null.

1.3 Use a network cable to connect the Ethernet port of the laptop to the NMS/COMport on the system control, switching, and timing board.

CAUTION:



Ensure that the network cable is properly connected to the Ethernet port of thelaptop and the NMS/COM port on the system control, switching, and timing board.Otherwise, the equipment or test tool may be damaged.

NOTE:

The NMS/COM port on the system control, switching, and timing board is a self-adaptive port for crossover cables and straight through cables. Thus, a straightthrough cable can also be used to make the connection. For the wire sequences ofcrossover cables and straight through cables, see Network Cable in the OptiX RTN980 Radio Transmission System IDU Hardware Description.In this case, the indicators at the Ethernet port and the NMS/COM port are on(green). If the operating system on the laptop allows the prompt for localconnections, the prompt that the network has been connected is displayed. If theoperating system displays the prompt indicating the collision of IP addresses,change the IP address.

1.4 Optional: Set the IE to the default browser.

1.5 Optional: Set the security level of the IE to medium or lower.

1.6 Optional: Disable the interception function for pop-up windows.

NOTE:

If the other plug-ins also intercept pop-up windows, disable the interceptionfunction.

1.7 Optional: Set the options of the IE.

a. Run the IE.

b. Choose Tool > Internet Options in the tool bar of the IE.

c. On the Common tab, click Settings in the Internet Temporaries box.

If the entered user name and the password are both correct, the NE List page isdisplayed in the IE.



2 Creating NEs

2.1 Using the Search Method

The Web LCT can find all NEs that communicate with a specific gateway NE by using the IPaddress of the gateway NE, the IP address range of the gateway NE, or the NSAPaddresses. In addition, the Web LCT can create the NEs that are found in batches. Comparedwith the method of manually creating NEs, this method is faster and more reliable.

Prerequisites

The communication between the NMS and the NE must be normal.

The NE user must have the authority of Operation Level or higher.

d. Optional: Select an existing network segment, and click Delete to delete thenetwork segment.

NOTE:

During initial configuration, Domain is 129.9.255.255 by default. After the gateway NE IP

address of the searched NE is changed, you need to change the value of Domain. The

default network segment cannot be modified and deleted.

the detailed operations, see Aligning the Single-

Polarized Antennas.



The ODUs are installed

separately from the

antenna

Proceed to the next step.

16.2 Power off the vertically polarized ODUs at both ends of the radio link, power on thehorizontally polarized ODUs at both ends of the radio link, and thus ensure that theantennas transmit horizontally polarized signals.

16.3 Adjust the azimuth angle and elevation angle of the antennas at both ends byreferring to Aligning the Single-Polarized Antennas, and ensure that the main lobe ofthe horizontally polarized signals is aligned with the antenna.

16.4 Measure the RSL (P1) of the horizontally polarized signals at the local end.

d. Calculate the XPD1 (XPD1 = P1 - P2).

If... Then...

The calculated XPD1 (XPD1 = P1 - P2) should be less than

30 dB.

Proceed to the next

step.

The calculated XPD1 (XPD1 = P1 - P2) should not be less

than 30 dB.

Perform 6.



e. Release the holder of the feed boom to some extent, and turn the feed boomslightly until the signal level reaches the lower threshold. The calculated XPD1(XPD1 = P1 - P2) should not be less than 30 dB.

16.6 Record the angle (D1) of the current feed boom.

16.7 Power off the horizontally polarized ODUs at both ends of the radio link, power on thevertically polarized ODUs at both ends of the radio link, and thus ensure that theantennas transmit vertically polarized signals.

NOTE:



If D1 and D2 are the same, you need not adjust the feed boom.

16.12Tighten all the screws of the antennas.

NOTE:

Use the multimeter to measure the received value of RSSI. Avoid any fault in the

alignment of antennas in the process of tightening the screws.

17 Checking the Status of Radio Links
