Nokia BTS Manager 2 Nokia BTS Manager This chapter gives instructions on how to get started with Nokia BTS Manager. It is assumed here that the user knows how to use Windows 95 or NT4.0 software. 2.1 Starting and exiting the BTS Manager The installation program of the manager SW creates a Nokia BTS Manager icon on the desktop and defines its parameters. For more information on the installation, refer to the Nokia BTS Manager online Help or the instructions on the Nokia BTS Manager CD-ROM case.
Nokia MetroSite Base Station Commissioning To exit the BTS Manager, choose the Exit command on the File menu. 2.2 Using Help The Nokia BTS Manager software has a convenient, context-sensitive online Help facility for getting information about a task you are going to perform, a feature you might want to know more about, or a command you may want to use.
Commissioning 3 Commissioning 3.1 Commissioning with Nokia BTS Manager’s Wizard The commissioning is done with Nokia BTS Manager’s Wizard. It is assumed here that the LAPD links and the PCM port are activated at the BSC. The BCF is in the ‘unlocked’ state. Before beginning the commissioning do the following: 1. Check that the Abis cables are connected. 2. Check that the Nokia MetroSite BTS is powered up. 3. Connect the Nokia BTS Manager PC to the BTS’s LMP port.
Nokia MetroSite Base Station Commissioning 4. Check that you have the required Site IDs and transmission capacity tables, or that the correct Site Configuration File (SCF) exists on the PC hard disk. Note The Site Configuration File is an unformatted ASCII file which contains site parameters for several sites under a BSC. The file is created from the NMS/2000 database and it can be retrieved to the Manager PC via a Web server interface to the NMS/2000 (refer to NMS/2000 documentation).
Commissioning Figure 1. 5. Manual Commissioning option The configuration data for the site(s) is stored on your PC in a Site Configuration File (SCF) under a certain pre-defined name. Open the file, select the site to be commissioned and click Next. The next time you launch the Commissioning Wizard, this page automatically displays the Site Configuration File you used in the previous session.
Nokia MetroSite Base Station Commissioning Figure 2. Site configuration file and site name list Note If the EAC inputs will not be used, just click Next. 6. Check the EAC inputs if they will be used. If the SCF is available and the EACs are defined in it, the ‘In Use’ information is read from the SCF; otherwise you have to mark the required EACs as ‘In Use’. The state of each EAC will change in real time as you test them, e.g. if you blow some smoke on the smoke detector.
Commissioning Figure 3. EAC inputs Note If the EAC outputs will not be used, click Next. 7. Check the EAC outputs (if they will be used) by changing the EAC states. If the SCF is available and the EACs are defined in it, the EAC output information is read from the SCF; otherwise you have to first mark the required EACs as ‘In use’. When you have finished the EAC output settings, click the Set Outputs button to send the information to ther BTS. After you have completed checking, click Next.

Commissioning 9. Click the Traffic Manager button to open the Traffic Manager dialog box. The Next button is disabled until you return from the Traffic Manager. Figure 6. 10. Traffic Manager button Allocate transmission capacity to the BTS with the Traffic Manager (refer to 3.2) and, when completed, click OK. This will establish a transmission connection between the BTS and the BSC. (In case the connection fails, refer to chapter 5, Troubleshooting and fault reporting.
Nokia MetroSite Base Station Commissioning During the BTS/BSC start-up scenario the BSC checks the BTS SW and if it is not the correct one, the BSC loads SW to the BTS. This downloading will take from 5 to 20 minutes depending on the link speed. If no SW downloading takes place, the process will take about 10 seconds. After that the BSC sends the configuration data to the BTS. 11. When the BCF is in the ‘Supervisory’ state and the TRXs are ready for testing, the BTS tests are run under the BSC’s control.
Commissioning Figure 7. Test events 13. Check the BTS Commissioning Report. 14. Type a name for the BTS Commissioning Report in the Save As field. By default, the Commissioning Report is saved to the \NOKIAMGR\REPORTS folder. To specify a different path for the report, click Browse and navigate to the folder you want. 15. Click Finish. The Commissioning Wizard closes.
Nokia MetroSite Base Station Commissioning Figure 8. BTS Commissioning Report 16. Quit the BTS Manager. 17. Disconnect the BTS Manager PC from the Nokia MetroSite BTS’s LMP port. The commissioning parameters are stored in the flash memory of the Master TRX (i.e. TRX1). The Master TRX creates back-up copies of these parameters in the slave TRXs’ flash memory.
Commissioning 3.2 Allocating transmission capacity with Traffic Manager The Traffic Manager is a graphical tool that allows you to allocate BTS transmission capacity independent of which Nokia MetroSite transmission unit is used. You need only to define the line interface (e.g. Port 1) and the incoming timeslot allocation on the Abis according to the transmission plan. With the FXC E1/T1 Symm transmission unit, the cross-connections are created automatically after the capacity has been set and approved.
Nokia MetroSite Base Station Commissioning Allocate transmission capacity as follows: 1. Select the line interface used (Port 1 - Port 16, depending on the transmission unit). 2. Click the appropriate traffic or signal button. 3. Click in a cell in the Abis timeslot allocation table. 4. Select an option, e.g. link speed, as required by the SW. (The selections are different depending on the signal type.) The SW then automatically reserves the time slots and bits to be used for the selected function.
Commissioning OMUSIG/TRXSIG1 The BTS can have one combined OMUSIG/TRXSIG1 which allocates 2, 4 or 8 bits in one timeslot depending on the link speed used (16 - 64 kbit/s). When a compressed Abis timeslot allocation is used, the OMUSIG/TRXSIG1 can be located in TCH/TS0 or TCH/TS0 - TS3 which means that it overlaps the TCHs which are reserved for a TRX (normally TRX1). TCHs The BTS must be allocated at least as many TCHs as there are TRXs installed in it (1 - 12).

Commissioning report 4 Commissioning report After the actual commissioning, the Commissioning Report is saved in a file on the PC hard disk (by default in the NOKIAMGR\BTSMAN\REPORTS folder). The report is an ASCII text file that you can open and check with Notepad or any word processor. The Commissioning Report can be sent to the NMS/2000 via the Web server. The report serves as the Site Acceptance document. 4.

Troubleshooting and fault reporting 5 Troubleshooting and fault reporting In the case of a failure in the commissioning procedure, an alarm will appear in the alarm window (refer to the BTS Alarm descriptions document in the SW release binder). Also, you may check the cause of a failure from the commissioning report and the diagnostic report. The commissioning procedure may fail, e.g.

Routing transmission capacity 6 Routing transmission capacity Routing of transmission capacity can be done in two ways, depending whether there is a cross-connection file available or not. If the cross-connection file exists, routing of transmission capacity is automated, i.e. the Site Configuration File refers to the name of the file and the embedded node manager opens the file and sends the settings to the transmission unit without any indication to the user by the SW.

(Another way to open the dialog box is to choose the Add command on the Cross-connections | Connections submenu.) 4. Define the following settings according to the cross-connection plan: • label, i.e. the name of the new cross-connection (max.
