Nokia BTS ManagerNTC DN999099 © Nokia Telecommunications Oy Internal Copy 9 (34)Issue 1 en DRAFT 3 DraftConfidentialNote2Nokia BTS ManagerThis chapter gives instructions on how to get started with Nokia BTS Manager. Itis assumed here that the user knows how to use Windows 95 or NT4.0 software.2.1 Starting and exiting the BTS ManagerThe installation program of the manager SW creates a Nokia BTS Manager iconon the desktop and defines its parameters. For more information on theinstallation, refer to the Nokia BTS Manager online Help or the instructions onthe Nokia BTS Manager CD-ROM case.Start the BTS Manager as follows:1. Double-click the BTS Manager icon on the desktop. The Nokia BTSManager starts with the Supervise and Alarms windows opened. Also, thesoftware checks the BTS configuration and displays it in the Supervisionwindow.2. Enter the MMI password if MMI password checking is on (this is the casewhen you work in Windows 95 environment).3. Enter the BTS password if BTS password checking is on. The softwarecontinues execution only if the BTS accepts the entered password. Youmay enter an invalid password three times before the BTS Manager exits.You can define different Manager options and communications parameters whenstarting to work with the BTS Manager.The BTS Manager PC must be connected to the BTS in order to make the BTSpassword checking possible. If no connection exists, password checking is notapplicable.

CommissioningNTC DN999099 © Nokia Telecommunications Oy Internal Copy 11 (34)Issue 1 en DRAFT 3 DraftConfidential3Commissioning3.1 Commissioning with Nokia BTS Manager’s WizardThe 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. SeeAppendix A for a description of the LMP cable.
Nokia MetroSite Base Station Commissioning12 (34) © Nokia Telecommunications Oy Internal Copy NTC DN999099Confidential Issue 1 en DRAFT 3 DraftNoteNoteNote4. 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.The Site Configuration File is an unformatted ASCII file which contains siteparameters for several sites under a BSC. The file is created from the NMS/2000database and it can be retrieved to the Manager PC via a Web server interface tothe NMS/2000 (refer to NMS/2000 documentation). During the commissioningprocedure, the parameters for the selected site are automatically read from thefile.The file can be modified locally using the SCF Editor, which is delivered on theNokia BTS Manager CD-ROM. For details on how to install the editor, refer tothe instructions on the CD-ROM case. For information on how to use the editor,refer to the application’s online Help.BTS SW is loaded to the BTS by the manufacturer. There is usually no need tolocally load SW to the BTS during commissioning.Start the commissioning as follows:1. Start the Nokia BTS Manager by double-clicking the BTS Manager iconon the desktop.2. Enter the MMI and BTS passwords, if required.3. When the BTS Manager indicates that the BTS is in the ‘BCFcommissioning’ state, choose the Wizard command on the Commissioningmenu.4. Select the Manual Commissioning option and click Next.Commissioning can be done only with a non-commissioned BTS. If the BTS isalready commissioned, you need to run the Undo Commissioning procedure first.

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. Traffic Manager button10. Allocate transmission capacity to the BTS with the Traffic Manager (referto 3.2) and, when completed, click OK. This will establish a transmissionconnection between the BTS and the BSC. (In case the connection fails,refer to chapter 5, Troubleshooting and fault reporting.)When you click OK in the Traffic Manager, the TransmissionConfiguration page reappears. The Back button is disabled, because thetransmission parameters have already been sent to the BTS. If you need tochange any parameters you have specified prior to this point, you have torun the Undo Commissioning procedure first and then re-commission theBTS.When the Transmission Configuration page reappears, there is a shortdelay before the Wizard automatically proceeds to the next page. If theBTS Test Reporting page does not appear automatically, click Next toproceed.When the BTS Test Reporting page appears, there is a slight delay before theautomatic BSC-controlled tests start. If you click the Manual button to open theTRX Test dialog box and the BSC-controlled tests start, the dialog box closesautomatically.
Nokia MetroSite Base Station Commissioning18 (34) © Nokia Telecommunications Oy Internal Copy NTC DN999099Confidential Issue 1 en DRAFT 3 DraftNoteCautionNoteDuring the BTS/BSC start-up scenario the BSC checks the BTS SW and ifit is not the correct one, the BSC loads SW to the BTS. This downloadingwill take from 5 to 20 minutes depending on the link speed. If no SWdownloading takes place, the process will take about 10 seconds. After thatthe BSC sends the configuration data to the BTS.11. When the BCF is in the ‘Supervisory’ state and the TRXs are ready fortesting, the BTS tests are run under the BSC’s control. The BSC runsautomatic tests on the Abis link and on each TRX installed in the BTS.The TRX test will take about 6 - 7 seconds for one TRX, 15 seconds for 4TRXs (one radio time slot per each TRX is tested), while the Abis loop testwill take about 1 minute 50 seconds (all channels of every TRX are tested).If the establishment of the BTS/BSC connection does not succeed, the BTSremains in the ‘Waiting for LAPD’ state. Then you can click the Manual buttonto run local TRX tests. You can also run manual tests after the automatic BSC-controlled tests are over.In order not to interfere the operation of other sites, make sure that an RFattenuator is connected to every TRX in the BTS before you start local TRX tests.The BTS starts operating normally after the tests have been performed, ifthe TRXs are unlocked at the BSC. The BCCH TRXs’ LEDs are green andthe TCH TRXs’ LEDs are blinking green.12. Check the test results on the BTS Test Reporting page and click Next.The test results can be monitored at the BSC. It is also possible to request thelatest test results remotely from the NMS/2000.

Quit the BTS Manager.17. Disconnect the BTS Manager PC from the Nokia MetroSite BTS’s LMPport.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 theslave TRXs’ flash memory.For maintenance purposes, in the case of 1*TRX BTS, make a back-up copy ofthe timeslot allocation settings using the Traffic Manager’s export function (referto 3.2).At this point you should check the Alarms window for possible alarms generatedduring the commissioning. For alarm descriptions, refer to Nokia MetroSite BTSAlarm Descriptions.Complete the installation as instructed in Nokia MetroSite Base StationInstallation.
CommissioningNTC DN999099 © Nokia Telecommunications Oy Internal Copy 21 (34)Issue 1 en DRAFT 3 DraftConfidentialNote3.2 Allocating transmission capacity with TrafficManagerThe Traffic Manager is a graphical tool that allows you to allocate BTStransmission capacity independent of which Nokia MetroSite transmission unit isused. You need only to define the line interface (e.g. Port 1) and the incomingtimeslot allocation on the Abis according to the transmission plan.With the FXC E1/T1 Symm transmission unit, the cross-connections are createdautomatically after the capacity has been set and approved.If a Site Configuration File is used for transmission capacity allocation, the AbisTS Allocation table is filled automatically. You only need to check thecorrectness of the capacity allocation.Figure 9. Traffic Manager for allocating BTS transmission capacityIn the case of 1.5 MB links (T1), the Traffic Manager automatically reduces thenumber of timeslot rows in the table to 24.The capacity to be used is defined by selecting its signal type (TCHs, TRXSIG,OMUSIG, TRXSIG on TCHs or OMUSIG/TRXSIG1) and by reserving requiredtime slots and bits.
Nokia MetroSite Base Station Commissioning22 (34) © Nokia Telecommunications Oy Internal Copy NTC DN999099Confidential Issue 1 en DRAFT 3 DraftNoteNoteNoteAllocate transmission capacity as follows:1. Select the line interface used (Port 1 - Port 16, depending on thetransmission 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 aredifferent depending on the signal type.) The SW then automaticallyreserves the time slots and bits to be used for the selected function.5. Repeat steps 2 - 4 until all types of necessary BTS signals are marked.If you want to modify the allocation table at this point, you have to first deleteprior allocations. Click the right mouse button on the cells to be modified anddelete either one signal allocation, all signal allocations of a particular type ordelete all allocations for the selected port.6. Check that the signal timing (either ‘Normal’ or ‘Satellite’) is correctly set.7. Click the OK button to send the information to the BTS.If you want to modify the allocations after you click OK in the Traffic Manager,you have to first run Undo Commissiong and reset the BCF.When the link capacity restricts normal signal allocation, you can use the‘TRXSIG on TCHS’ and combined ‘OMUSIG/ TRXSIG1’ signal types.The signal types are discussed below in more detail:OMUSIGThe BTS can have one OMUSIG which allocates 2, 4 or 8 bits in one time slotdepending on the link speed used (16 - 64 kbit/s). If a combined OMU/TRXSIG1is used, the allocation of the OMUSIG is disabled.
CommissioningNTC DN999099 © Nokia Telecommunications Oy Internal Copy 23 (34)Issue 1 en DRAFT 3 DraftConfidentialOMUSIG/TRXSIG1The BTS can have one combined OMUSIG/TRXSIG1 which allocates 2, 4 or 8bits in one timeslot depending on the link speed used (16 - 64 kbit/s). When acompressed Abis timeslot allocation is used, the OMUSIG/TRXSIG1 can belocated in TCH/TS0 or TCH/TS0 - TS3 which means that it overlaps the TCHswhich are reserved for a TRX (normally TRX1).TCHsThe BTS must be allocated at least as many TCHs as there are TRXs installed init (1 - 12). Each TCH allocates 2 contiguous time slots (16 bits) for a single TRXeach of which is marked with the TRX number. The TCHs are numbered from 1to 12 in order of which they are defined.TRXSIGThe BTS must be allocated at least as many TRXSIGs as there are TRXs installedin it (1 - 12). Each TRXSIG can allocate 2, 4 or 8 bits in one time slot dependingon the link speed used (16 - 64 kbit/s). The TRXSIGs are numbered from 1 to 12in the order they are entered.TRXSIG on TCHsThe TRXSIG can be reserved on a traffic channel but then up to 4 traffic channelsare lost. The signal type must always start from the first bit of the channel.

Routing transmission capacityNTC DN999099 © Nokia Telecommunications Oy Internal Copy 29 (34)Issue 1 en DRAFT 3 DraftConfidential6Routing transmission capacityRouting of transmission capacity can be done in two ways, depending whetherthere 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 embeddednode manager opens the file and sends the settings to the transmission unitwithout any indication to the user by the SW.If the cross-connection file required is not available, you have to create the cross-connections manually using the Cross-connections tool (see the section below).6.1 Creating cross-connections manuallyCross-connections are created with the Cross-connections tool in the transmissionunit manager application.Cross-connections define how signals are routed from a FXC transmission unit toanother transmission unit. Cross-connections are created into banks which areeither active or inactive. The cross-connections in the active banks are in use,whereas those in inactive banks can be used for creating or editing cross-connections. The procedure below describes how to create bi-directional cross-connections.Create bi-directional cross-connections as follows:1. Start the Cross-connections tool by choosing the Open command on theTransmission menu in the BTS Manager. The manager application for thetransmission unit is launched and the BTS Manager session terminates.2. Open the inactive bank page. (The number of the active bank is givenabove the cross-connections list view.)
