3. Node B Commissioning

This section explains in detail the steps mentioned in the previous section.

3.1. Format DUW

Connect the serial cable to the LMT A port of DUW and run Tera Term software.

Make sure that you see the command prompt $

Put the Node B in BackUp mode, by issuing the following command.

reload—

We can check the directories within the NodeB by issuing

vols

Since the /c2 is not automatically mounted, we will have to manually mount the drive by issuing the following command.

mount_c2

vols

Now we will proceed with the formatting of the hard drives /c2 and /d. The commands to do
the format is given below.

formathd /c2

formathd /d

Once the format is done, reload the RBS. After this is done, we again move to the back up mode to start the configuration. This is done by issuing a reload – command

The next step is to proceed with setting the IP address in the nodeB. The command issued is

ifconfig le0 169.254.1.1 netmask 255.255.0.0

Set the IP address in your laptop to 169.254.1.2.

Make sure that you set the Default gateway IP address in the laptop without which the integration scripts will fail.

3.2. Transfer the Basic software package to NodeB.

Open an FTP client such as Filezilla and connect to the RBS IP address 169.254.1.1 through LMT B port of DUW

Make sure you select the root directory ‘/’ at the RBS side.

Transfer /c2 and /d directories to the RBS as shown below.

Once the transfer is completed make sure the size of /c2 is 129M and /d is 39M. This can be done by issuing the vols command

3.3. Restart Node B with basic software

Now we have to restart the RBS with the basic software. The command to be issued is

reload. Wait till the RBS restart is completed

We login to the RBS using the element manager software. The local maintenance IP address of the RBS 6201 is always 169.254.1.1.

Checking the Finger print

This section shows a series of screenshots on how to check the finger print of the RBS. The finger print is used to generate the license key file for the RBS.

3.4. Run Cabinet Equipment Wizard

The RBS is configured with the cabinet type when we run the Cabinet equipment wizard. Also some basic sector and IP definitions are done in the Cabinet equipment configuration. The script to be run is 1_Cabinet.xml.

From the tools menu, select Cabinet Equipment configuration. We can choose the wizard or the scripts option. Since cabinet equipment configuration is quite simple, we will be running the wizard manually. Please follow the screenshots below.

Click Next

Since we are running the wizard manually click Next. The RBS will proceed with a restart and it is a normal behaviour. Wait for the restart to complete.

Once the restart is completed, you will see a screen as mentioned below. Click Next

In the next screen you will select the RBS cabinet type, key in the cabinet information and select the Radio Building blocks for the sectors. We will be using the radio building block RBB12_1A. In this example we will be configuring two sectors. Click next once done.

In the next page you will see the power supply and the battery configuration. Key in the number of PSU’s and the battery backup in Ampere Hour if applicable. Click next once done.

The next page shows the Local maintenance IP address and the subnet mask. The default IP address for the RBS is 169.254.1.1 and netmask is 255.255.0.0. Click next once done.

Please confirm the parameters and select the option to restart the RBS after cabinet equipment configuration.

Observe in the Teraterm that the RBS is starting up in the Initial CV

3.5. Run OAM Wizard

Now that the Cabinet equipment configuration is completed, we will run the 2_OAM_Script.xml through the OAM Access Configuration Wizard. This will configure OAM IP address, the OAM VLAN, the OAM Gateway , OAM Subnet mask, the Iub IP address(User Plane/ Control Plane IP), the Iub VLAN, the Iub Gateway and the Iub subnet mask. In addition to this we will also define the server IP addresses specific to Singtel.

To run the OAM wizard, from the tools menu select OAM access configuration.

You will see the screen below.

Since we will be using the 2_OAM_Script.xml select Use Configuration file and browse the file from the folder where the OAM file is stored.

Once the current configuration is loaded, click next.

The following screens show the parameters that have been defined through our scripts.

This screen shows the Local Maintenance IP address and the subnet mask.

The next screen shows the OAM IP, OAM VLAN, OAM Gateway and OAM subnet mask configuration. Also we select the Transmission type (TNB). TNB is used for Optical Gigabit Ethernet through SFP and is required for IPRAN sites.

This screen shows the Iub IP address, Iub VLan, Iub Gateway,Iub Subnet mask and the IP Sync Ref IP addresses.

The next screen shows the next HOP IP address which s required for OAM access. The next hop IP address will be the OAM Gateway IP address.

The next screen shows the Server configuration inside the Singtel network and they are standard values. Click next once done.

The next screen shows the NTP servers for the time setting in the RBS.

The next screen shows the Network Synchronization available. We have configured two IP Sync Ref’s in the RBS. Therefore we will see 2 entries here.

Confirm the parameters that have been entered in the OAM script. Click Finish

3.6. Run Site Equipment Configuration

The next step is to run the Site Equipment configuration. We will be running 3_Site_Equipment_script.xml.

The site equipment configuration defines the site name, number of carriers/sector, defines the external equipment such as ASC, and the feeder cable settings.

To invoke the Site equipment configuration, go to Tools à Site Equipment configuration.

Select the Site equipment file 3_Site_Equipment.xml and

Click next

This screen shows the Site name and the logical name.

The next screen shows the SAU and the PSU configuration. SAU is currently used only for the 6102 sites.

The next screen shows the Sector Data info including the latitude and longitude.

The next screen shows the Carrier configuration on per sector basis.

The next screen shows the ASC configuration.

The next screen defined the band at which the RU’s will operate.

The next screen shows the Antenna feeder configuration.

The following screen shows the parameter numhscoderesources and numeulresources. Set the parameters according to the requirement.

Confirm the parameters in the next screen by clicking Finish.

Once the Site Equipment configuration is done, you will see the following screen.

3.7. Run Iub Transport script

Now we will proceed to run the 6_Iub_script.mo. This will define the Iub link towards the RNC

From the tools menu select Run Command file

From the screen below select the Iub script by clicking Browse.

Make sure you select “Halt on Errors” and Verbose logging” before clicking the Start button.

Once completed you will see the following messages.

3.8. Activating Integration Unlock

We assume that during RBS integration, we do not have the License Key file. In the event of not having the LKF, we can activate a feature called “Integration Unlock”. This feature is conceptually similar to the “Emergency Unlock” feature. All the RBS software and hardware licenses will be available for a maximum period of 7 days. The advantage of the feature is that we need to touch the Emergency Unlock feature this reserving it for emergency purposed and at the same time have the same functionality.

The command to activate integration unlock (to be done at Teraterm) is

$ license iu activate

The command to check the status of Integration unlock (to be done at Teraterm) is

$ license iu status

Please see the screenshots below for details.

3.9. Run HS/EUL script

This script is required for the HS/EUL features to work properly. It is an .mo script and to run it go to Tools à Run Command file

Browse for the HS/EUL script.

Click on “Halt on Errors” and “Verbose Logging” and click Start. You should

3.10. Changing the RUW power to 60 Watts

Most of Singtel RBS sites require that the each carrier supports 30 Watts. Since we have configured 2 carriers per RUW, we will have to set the total power of RUW to 60 Watts. Thus each carrier will have a power of 30 Watts.

We will have to set the power for all the RUW’s in the RBS.

From the MOM view in the Element Managed, browse to the following path

ManagedElement -> Equipment->RbsSubrack->RbsSlot-> AuxPlugInUnit>RruDeviceGroup->TpaDeviceSet->TpaDevice

In the MO properties window set

maxTotalOutputPower = 60

Click on Apply to confirm the settings.

3.11. Installation of the License Key File

After obtaining the License Key File, we will be proceed with LKF installation.

Open the FTP server software in your laptop(such as Filezilla Server)

Click on the Users icon

Select the folder where the license key file is installed.

Once the selection of the folder is done, click OK

In the Element Manager go to Licensing View. Go to MO properties and select “Update LicenseKey File”.

Now in the following page, key in the following details of the FTP Server(our Laptop). Username, Password, IP address and the License File Name. It is shown in the screen shot below.
