Exit BTS HW Configurator.

Next, proceed with the transmission configuration (see Section 2.3).

2.2.1

Hardware information file The Passive Units view in BTS HW Configurator allows you to enter information concerning all units that are not autodetected. This information includes part and serial numbers. This information is not required during commissioning and is not needed to get the BTS operational. It is possible to enter and update this information any time before, during, and after commissioning.

26 (80)


DN99109435 Issue 3-0 en


You can enter passive unit information with BTS HW Configurator off-line and on-line. A barcode reader can also be used to scan the part and serial numbers off stickers on the units. The SW recognizes the part number and identifies the unit type. One problem is that using a barcode reader with the PC requires the use of one serial port and many laptop computers have only one serial port. In this case, BTS HW Configurator must be used off-line to scan in the part and serial numbers. Once this is completed and the information is saved to a file, the hardware information file (.hwi) can be downloaded to the BTS.

Note If you are to change the HW configuration in any way after the BTS commissioning has been finished, you would have to perform a BCF reset in order to make the changes active.

2.3

FXC transmission unit configuration The transmission of the BTS and its Hub node must be configured and tested during the commissioning with Nokia UltraSite BTS Hub Manager. FXC transmission units can be commissioned manually or commissioned based on a node file. Manual commissioning is described in section 2.3.1. Commissioning based on a node file is described in section 2.3.2.

Note If there is an FC E1/T1 transmission unit in the BTS configuration, that unit is configured in the Commissioning Wizard in BTS Manager (see 2.4).

Check that the signal timing (either ‘Normal’ or ‘Satellite’) is correctly set.

6.

Click the OK button to send the information to the BTS.

Note When the link capacity restricts normal signal allocation, you can use the ‘TRXSIG on TCHS’ signal type. The signal types are discussed below in more detail: OMUSIG

The BTS can have one OMUSIG which allocates 2, 4 or 8 bits in one time slot depending on the link speed used (16 or 64 kbit/s). TCHs

The BTS must be allocated at least as many TCHs as there are TRXs installed in it (1 - 12). Each TCH allocates 2 contiguous time slots (16 bits) for a single TRX each of which is marked with the TRX number. The TCHs are numbered from 1 to 12 in order of which they are defined. TRXSIG

The BTS must be allocated at least as many TRXSIGs as there are TRXs installed in it (1 - 12). Each TRXSIG can allocate 2, 4 or 8 bits in one time slot depending on the link speed used (16, 32 or 64 kbit/s). The TRXSIGs are numbered from 1 to 12 in order of which they are entered. TRXSIG on TCHs

The TRXSIG can be reserved on a traffic channel (TCH) but then up to 4 radio time slots (8 bits) are lost. The signal type must always start from the first bit of the channel. 2.3.1.6

Creating cross-connections

As there is no Cross-connections file available, cross-connections for each transmission unit are created with Nokia UltraSite BTS Hub Manager’s crossconnections tool. This FXC transmission unit configuration work includes also cross-connections on the D-bus. Cross-connections define how signals are routed from an FXC transmission unit to another transmission unit. Cross-connections are created into banks which are either active or inactive. The cross-connections in the active banks are in use, whereas those in the inactive banks can be used for creating or editing crossconnections. The procedure below describes how to create bi-directional crossconnections manually.

44 (80)

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, and the BCF is reset automatically, which means that the Supervision and Alarms windows disappear for a few seconds, but the commissioning procedure continues after the BTS has started normally. If no SW downloading takes place, the process will take about 10 seconds. After that the BSC sends the configuration data to the BTS. If the oven oscillator has not yet warmed up, the BCF remains in the 'Configuring' state. It can take a few minutes for the oven oscillator to warm up after the BTS is powered on. The BTS Events list displays a message when the oven oscillator is ready. When the BTS is ready for testing, the Wizard automatically proceeds to the next page and the BSC runs automatic tests on the Abis link and on each TRX installed in the BTS.

Note If there is no BSC connection (the BCF remains in the ‘Waiting for LAPD’) state and you click Next, the Wizard asks if you want to give the Use Current command. If you click Yes, the BTS starts to use the BTS SW in the BOI unit memory and the Wizard proceeds to the BTS Test Reporting page. If you click No, the BCF remains in the ‘Waiting for LAPD’ state, until the BSC connection (OMUSIG link) is established. 6.

64 (80)

When the BTS Test Reporting page appears, there is a slight delay before the automatic BSC-controlled tests start (see Figure 46). If you click the Manual button to open the TRX Test dialog box and the BSC-controlled tests start, the dialog box closes automatically.

Caution In order not to interfere the operation of other sites, make sure that an RF attenuator is connected to every TRX in the BTS before you start local TRX tests.

Note The following is an explanation of TRX test results (see Figure 46): • TX power level should be 47 dBm, +/- 4 dBm, otherwise the test fails. • The TRX sensitivity value in laboratory conditions is typically from -109 dBm to -111 dBm. In field conditions with interference, an acceptable value can be around -100 dBm. • BER in RF part should not be bigger than 2%, otherwise the test fails. BER in BB part should not exceed 0%, otherwise the test fails.

Troubleshooting and fault reporting

4

Troubleshooting and fault reporting In the case of a failure in any part of the whole 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 reports. The commissioning procedure may fail, e.g. when: •

the RX and TX cables are not properly connected, then the TRX test fails.

•

the Abis cables are not properly connected (then the transmission unit LED is not green)

•

the pre-configuration failed at the BSC, e.g. the BCF and TRX objects were not created

•

the oven oscillator has not yet warmed up (then the BCF remains in the ‘Configuring’ state)

•

the TRXs are not unlocked at the BSC (then the TRXs do not enter the ‘Supervisory’ state)

•

the PCM port is not activated at the BSC.

Abis loop test measures bit transfer errors between the BTS and the BSC. If the BER value is bigger than normal that might indicate trouble between the BSC and the BTS. Before starting to re-commission the BTS, first run the Undo Commissioning procedure in BTS Commissioning Wizard.
