6 BTS Installer User Guide (CENG0048) 6.1 Introduction 6.1.1 Purpose and Scope The purpose of this document is to provide the user of the ip.access software package, “BTS Installer”, with the knowledge to use the application to its full potential. Using BTS Installer, the user is able to configure (and reconfigure) nanoBTS™ installation parameters, download new software to nanoBTSs and perform Network Listen tests.
• Download certificate revocation lists to the nanoBTS from time to time BTS Installer contains tools to carry out all these actions. It can do so • • • To one nanoBTS at a time or several nanoBTSs at once. Automatically or manually. According to information either loaded from a configuration file or entered via the graphical user interface. To allocate IP addresses and other IP configuration to nanoBTSs, BTS Installer contains a built-in DHCP server.
6.3 Concepts This section describes some basic concepts behind the operation of BTS Installer; without an understanding of these it will be difficult to make sense of instructions for using the tool. Figure 24 is an illustration of BTS Installer’s user interface, and this is referred to when explaining some of these concepts. Detailed explanations of all aspects of the user interface will be found in later sections. Figure 24 - Main Display © ip.
6.3.1 The BTS Database BTS Installer will only operate on a nanoBTS that it knows about. The collection of nanoBTSs that BTS Installer knows about is called the BTS Database. The BTS Status section at the bottom of the graphical user interface is a display of the current status of each entry in the BTS Database – each row in this table represents one nanoBTS that BTS Installer knows about.
6.3.2 Configuration Phases Configuration of a nanoBTS takes place in a number of phases. In automatic mode (see section 6.3.3.1) all enabled phases are run automatically one after another in a fixed order; in manual mode the user chooses which phase to run, one at a time, and can also perform other actions which are not equivalent to automatic configuration phases.
• A particular nanoBTS is not operating correctly. Manual mode is used to investigate its configuration and diagnose and fix the problem. 6.3.3.2 The Unknown BTS Mode Normally the BTS Database contains entries for specific nanoBTSs. In particular the DHCP server will only normally only supply an IP configuration to a nanoBTS whose MAC address matches that explicitly specified in the BTS Database entry.
Direct connection or proxy mode is indicated to the user in the status bar at the bottom of the user interface. A later section explains how to start BTS Installer in proxy mode, and lists the limitations of BTS Installer whilst in proxy mode. 6.3.4 The Configuration File BTS Installer can be given the information it needs • • • in a configuration file, or via the graphical user interface, or via some combination of both.
6.4 Getting Started This section contains information about installing BTS Installer, preparing it for use, and performing an operation on a nanoBTS. 6.4.1 Installing BTS Installer BTS Installer is a Java application. It requires that the Sun J2SE Java Runtime Environment be installed: version is 1.5 is required (there is no particular requirement as to which subversion of 1.5 is used). The J2SE Java Runtime Environment is available, with installation instructions, from Sun’s Java web-site (http://www.
6.4.2.4 Command Line Arguments On all platforms, additional command line arguments can be used to specify that BTS Installer should run in proxy mode, and/or to specify the IP addresses and optionally Unit IDs of some nanoBTSs for which BTS Installer should create BTS Database entries. See section 6.9.3 for details of these command line arguments.
• • Configuration file – see section 6.5.1.3 – this need not be set up unless and until you wish to use a configuration file Options – see section 6.5.1.4 – these usually do not need to be set up as the default values are usually adequate. 6.4.5 Creating a BTS Database Entry BTS Installer will not operate on any nanoBTS that it doesn’t know about; in order to do anything to a nanoBTS it must have a BTS Database entry for that nanoBTS (see section 6.3.1 and section 6.5.4.2).
Use the Edit button to pop up the BTS Configuration dialog box on which desired attributes may be entered. See section 6.7 for complete details of the BTS Configuration dialog box. 6.4.8 Perform desired operations At this point any desired operation may be performed on the nanoBTS: • • • automatic configuration – use the Auto button manual configuration – use the Action button network listen functions – use the Listen button. Section 6.
6.5 User Interface Reference BTS Installer’s user interface is divided into four areas, as shown in Figure 24. Each area is described in detail in this section. 6.5.1 BTS Installer Configuration section The first section of the user interface contains settings concerned with the operation of BTS Installer itself. The user must set up a Log File Directory – there are two ways of doing this, see section 6.5.1.1 or section 6.5.1.3.
6.5.1.1 Log file directory selection BTS Installer insists on logging everything interesting it does. So it won’t do anything much, and most functions will be disabled, until a log directory has been specified in which it can create log files.
6.5.1.2 IP address selection Some operations of BTS Installer require it to know its own IP address and/or subnet mask. Where the application is running on a computer with more than one Ethernet adapter there is no way that the tool can know which of its multiple IP addresses it should be using. To tell BTS Installer which IP address and subnet mask it should be using, use the “Configure” button in the “BTS Installer Configuration” panel (see Figure 28).
These options are stored persistently so are remembered next time BTS Installer is run. Whenever these options are changed the DHCP server will need to be stopped and restarted in order to notice the new values. 6.5.1.3 Configuration file Once the IP address has been selected and the log file directory has been specified most functions of BTS Installer are available and can be used without loading a “configuration file”.
6.5.1.4 Options The user selects the Bts Installer Options using the Configure button in the Options panel. This should pop-up an Options dialog box that gives access to a number of settings. The Options dialog box (Figure 30) allows the user to change the default timers, the reconnection attempts and also the window size used during software download.
• later versions of nanoBTS software shut down more quickly then this delay could be reduced to speed up operation. After performing an operation in which BTS Installer resets the nanoBTS and then has to reconnect to it, it attempts reconnection the number of times specified by Reconnect retries, and gives up on each connection attempt after the time specified by Connecting to the BTS.
Colour Yellow Green Red Symbol question mark tick cross Meaning This IP address has been offered to a nanoBTS which has not yet accepted or rejected it This IP address is allocated to a nanoBTS This IP address has been offered but the nanoBTS has rejected it Figure 32 - IP Address Pool Clicking on column headings will sort the display. The Add button allows one or more IP addresses to be added to the pool. The example in Figure 33 will add the addresses 192.168.0.200, 192.168.0.201, 192.168.0.202, 192.
The sequence of log entries shown in Figure 34 is a typical sequence showing the DHCP server receiving a request from a nanoBTS and allocating it an IP address from the IP address pool. You may see other “Received:” messages which are nothing to do with nanoBTSs: the DHCP server will not respond to these. If you see “Received:” messages which you believe are from nanoBTSs and to which you expect the DHCP server to reply, but you don’t see replies from the DHCP server, please review section 6.6.
During automatic configuration, messages will be written to the log window and the log file indicating each stage of processing for each nanoBTS. Any error messages relating to any configuration failures will also be logged. As automatic configuration proceeds the various colour codes shown in the BTS Status window will be updated.
UNIT ID NV Attr D’LOAD What BTS Installer thinks about the current state of the UNIT ID set for this nanoBTS What BTS Installer thinks about the current state of the non-volatile attributes for this nanoBTS What BTS Installer thinks about the firmware currently loaded on this nanoBTS The coloured indicators have the following meanings: Colour Grey Symbol none Green tick Yellow question mark Red cross Meaning The configuration phase is disabled for the nanoBTS, and BTS Installer is making no statem
Pressing the Find button causes BTS Installer to look for nanoBTSs on the local area network and display the results as shown in Figure 37. The display can be sorted on any column by clicking on the column heading. If BTS Installer is running on a computer that has more than one network adapter installed and enabled, Find will look for nanoBTSs on all of the connected local area networks unless the Listen Only on This Address option is ticked on the Configure BTS Installer dialog box (see section 6.4.
6.5.4.2.2 Creating a New BTS Database entry The New button will create a new blank BTS Database entry. It will pop up a BTS Configuration dialog box to allow you to edit the attributes of the BTS. See section 6.7 for a complete reference to all the attributes. 6.5.4.3 Deleting BTS Database entries To delete one or more BTS Database entries, select them in the BTS Status window and press the Delete button. 6.5.4.
6.5.5 Manual configuration operations The Configure BTS dialog box (see Figure 38) gives access to a number of manual BTS configuration operations. Figure 38 - Configure BTS dialog box The status displays show the same information as in the relevant row in the BTS Status window, with the addition of the filename of any software configured for downloading. The Edit button is an alternative means of opening the BTS Configuration dialog box to edit this nanoBTS’ attributes.
If the operation fails then an error message will be displayed in the progress dialog box and you will need to use this message to diagnose and correct the problem. The Cancel button on a progress dialog box can be used at any time to abandon the operation. This changes to a Close button when the operation has completed, whether successfully or not. An open or closed padlock is displayed to indicate whether the connection is insecure or secure (SSL) – see section 6.
6.5.5.4 Set/Get NV Attributes The Set/Get NV Attributes button is used to perform some or all of • • • Set new values for some or all non-volatile attributes in the nanoBTS Fetch some or all of the values of non-volatile attributes from the nanoBTS Fetch some or all of the current values of attributes from the nanoBTS The “NV” value of an attribute can differ from the “current” value of an attribute in some cases because some changes to some non-volatile attributes do not take effect immediately.
In addition there are some NV attributes that cannot be fetched in this way either. These are: • Current SW Configuration – use the Set Current SW and Fetch HW & SW Configuration commands to examine and change the current software configuration. When the Set/Get NV Attributes command has completed the BTS Configuration dialog box is displayed showing any values fetched. See section 6.7 for a full description of that dialog box. 6.5.5.
6.5.5.6 Set Current SW The Set Current SW button fetches information about the current software configuration from the nanoBTS, and allows the user to change the software configuration, ie specify which software will run next time the nanoBTS is restarted. There is also an option to restart the nanoBTS. First this command fetches the current software configuration and displays it in the dialog box show in Figure 41.
6.5.5.8 Fetch HW & SW Configuration The Fetch HW & SW Configuration button fetches • • • • software configuration information hardware configuration information in service time, the cumulative number of hours for which the nanoBTS has operated up time, the number of hours, minutes and seconds the unit has been operating since the nanoBTS was last (re-)started 1 and displays them in a dialog box as show in Figure 42.
6.5.5.9 Change IP Configuration The Change IP Configuration button pops up the dialog box shown in Figure 43 which displays the nanoBTS’ current IP address and allows the user to change the IP address, subnet mask and default gateway.
© ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.
The normal process for manual frequency adjustment is for the user to: • • • connect external frequency measuring equipment to the nanoBTS TIB out port using the correct type of cable use the Frequency Control command to change the Frequency Control attribute whilst observing the effects using the external measuring equipment stop when the nanoBTS is set to the required frequency (26MHz for nanoBTS models that are not multi-TRX capable, 1.
If the unit’s Up Time is equal to or greater than 24 hours, or if a warning message has been displayed and the user has selected the OK button, the Frequency Control dialog box is displayed, as shown in Figure 44 below. Figure 44 - Frequency Control dialog box BTS Installer automatically reads from the BTS all of the values for this dialog box when it is first displayed. The Timing Bus group box contains read-only information about clock sources and the status of the timing bus.
• • • whether it is supported on the nanoBTS unit in question whether it is currently available (ie. whether a clock source is present) whether it is currently the active clock source (ie. the one that the unit is taking its timing from) On nanoBTS models that are not multi-TRX capable, the Internal OCXO is always supported, available and active, and neither TIB Clock Input nor 10 MHz Input are supported. On other nanoBTS models, all three sources are supported.
6.5.5.11 Security The Security button allows the user to view certain attributes of the nanoBTS relating to whether and how the nanoBTS uses secure SSL connections, and allows the downloading of certificates and certificate revocation lists to the nanoBTS. When the button is pressed, BTS Installer fetches some attributes from the nanoBTS and then displays this dialog: The Security Possible attribute is a read-only attribute which indicates whether the nanoBTS is capable of making secure connections.
Note that as for some other non-volatile (NV) attributes there are two versions of the SSL Control attribute on the nanoBTS – the “NV” version, which says what the nanoBTS will do next time it is reset, and the “current” version, which says what it is doing now. BTS Installer displays the current version.
6.6 The DHCP Server 6.6.1 Function of the DHCP server The DHCP server can supply the following information to a nanoBTS which does not have an IP configuration: • • • IP address subnet mask default gateway. This information is necessary for the nanoBTS to be able to communicate with the other functions of BTS Installer and with the BSC. Details of how to design an IP network for nanoBTSs are outside the scope of this User Guide. 6.6.
• • • • • The DHCP server must have an IP address to offer to the nanoBTS, either configured explicitly or chosen from a pool, as described below, and the subnet mask and default gateway for the nanoBTS must be specified. The DHCP server must know the IP address of the interface on which it is to respond to requests – see section 6.5.1.2. The DHCP server must be running – when it is running the Start button will be disabled and the Stop button will be enabled.
6.6.4 Other IP configuration parameters In addition to giving each nanoBTS a unique IP address it is necessary to specify the subnet mask and default gateway that each nanoBTS will use. Normally you will want to set the same values for these parameters for all the nanoBTSs on a particular network. These parameters are set on the DHCP tab of the BTS Configuration dialog box, either for the particular nanoBTS or for all nanoBTSs using the Defaults button. See section 6.7.
• • • Select an entry for a nanoBTS in the BTS Status section of the user interface and press the Edit button – this produces a BTS Configuration dialog box that allows the attributes for that particular nanoBTS to be edited. Press the Defaults button – this produces a BTS Configuration dialog box that allows the user to edit default values that BTS Installer will use for all nanoBTSs that don’t have specific settings.
6.7.2 Current Values Display The BTS Configuration dialog box can show just the attribute values that the user wants to configure on the nanoBTS, as in Figure 45, or it can be expanded by selecting the “Current values >>” button to also show the current values of the attributes in the nanoBTS, if these are known, as shown in Figure 46.
displayed may or may not be up to date. These values are fetched from the nanoBTS as follows: • • When automatic configuration of the nanoBTS is performed, and the nonvolatile attributes configuration phase is enabled, then any non-volatile attributes that are configured on the nanoBTS are read back. BTS Installer does this to check that the values set have been correctly stored by the nanoBTS.
nanoBTS, as it is the IP address that BTS Installer will use to contact each nanoBTS for later configuration phases. In addition, when BTS Installer connects to a BTS via a Primary OML Proxy, BTS Installer identifies the nanoBTS it wants to talk to by quoting the Unit ID to the proxy, so in this case it is the Unit ID that is the most useful identifier for the nanoBTS. See section 6.9 for more information about proxy mode.
Each phase is enabled or disabled by a check box which is the first item on the first tab for that phase.
The IP address is displayed only if an IP address for this nanoBTS is known to BTS Installer and the IP address has not been allocated by BTS Installer’s built-in DHCP server from the IP Address Pool. So: • • • • • If you know the IP address of this nanoBTS, because it has already been allocated by some means external to BTS Installer, fill in the known IP address here. If you want BTS Installer to allocate a specific IP address to this nanoBTS using its DHCP server, fill in the desired IP address here.
6.7.7 The DHCP tab The DHCP tab, Figure 48, contains attributes to control the operation of the DHCP server with respect to this nanoBTS. In addition, if the DHCP configuration phase is enabled, the MAC address from the BTS tab is used by the DHCP server and the IP address from the BTS tab may be used by the DHCP server.
• • If BTS Installer is being used to connect to this nanoBTS in a temporary network configuration in order to perform some configuration of the nanoBTS before it is deployed to its final location then a finite lease is acceptable, as the nanoBTS does not need to continue to operate once BTS Installer has stopped running. If some other DHCP server is available on the network that will take over the job of BTS Installer’s built-in DHCP server once BTS Installer has stopped running.

Note that the BTS will usually refuse to active incompatible versions of Backhaul and TRX software.
6.8 Using Network Listen 6.8.1 Introduction to Network Listen Network Listen is a feature implemented by the ip.access nanoBTS, and controlled by BTS Installer, that aids frequency planning. It puts the nanoBTS into a receive mode in which it can be used like a mobile to identify other base stations (which may be cells in the macro network or in the nanoGSM™ network), to monitor their power levels, frequency usage and BCCH information.
At the bottom of the window there is a Connect button to control connection to the nanoBTS, Start Test and Stop Test buttons that control the running of the tests and an OK button that disconnects from a nanoBTS and then removes the Network Listen window. Figure 56 - Network Listen Main Display Before it is possible to run any of the tests it is first necessary to select the Connect button to start a management connection between the nanoBTS and BTS Installer.
6.8.3 Configuring a Network Listen Test In order to configure a test, first select the required test from the tabs on the left hand side of the Network Listen window. Then select the Configure Test button on the toolbar: Figure 57 - Configure Test Button which will bring up the Configure Test dialog box for the selected test.
6.8.3.1 Test Options Figure 58 - Test Options The “Test Options” tab allows the user to configure how many times the test runs and, if the test is to be run more than once, how long to delay between runs. Control Run the test - Times Run the test – Until stopped by user Delay between tests © ip.access Ltd COMPANY CONFIDENTIAL Description If selected, the test will be run the specified number of times. Default: 1.
6.8.3.2 ARFCN Lists Figure 59 - ARFCN Lists The ARFCN Lists tab allows the user to select channels to be either tested or not as required. To define a set of channels to test, select the Apply White List check box and then select the required ARFCNs from the list in the left hand panel. This will set Listen to test these ARFCNs only. To select ARFCNs to be explicitly ignored, select the Apply Black List check box and then select the required ARFCNs from the list in the right hand panel.
6.8.3.3 RXLEV Threshold Select the RXLEV Threshold tab and the window will show the selected properties for the receive level threshold (Figure 60). Figure 60 - RXLEV Threshold Control Apply RXLEV Threshold RXLEV Threshold © ip.access Ltd COMPANY CONFIDENTIAL Description If ticked, the RXLEV threshold will be applied. If not ticked, no RXLEV threshold will be applied and no test results will be excluded on the basis of signal strength.
6.8.3.4 Advanced Figure 61 - Advanced Options Control Test No Autonomously Report Test Duration © ip.access Ltd COMPANY CONFIDENTIAL Description The number used internally to identify the type of test to be performed. Not used. The period, in seconds, after which the nanoBTS should autonomously terminate a not-yet-completed test. If a test is terminated in this way, BTS Installer will display any partial test results that are available.
Control Test Precedence Description Determines the conditions under which the nanoBTS will allow the test to be performed. The default is Object must not have dedicated active channels. If set to Object must be Administratively Locked, the nanoBTS will only carry out the test if the Administrative State of its radio carrier object is set to Locked or the radio carrier object has not yet been Op Started.
Figure 62 - Channel Usage Test Results The resulting display is very similar to that which one would expect to see if the band was monitored using a spectrum analyser. To examine the test results more closely click on the magnifying glass with the + sign in the upper left hand part of the display. This will zoom in on the display to show it in more detail. The magnifying glass with the – sign will zoom out from the display.
6.8.5.1 Test Configuration All the tabs on the Configure Test dialog box for the BCCH Channel Usage test have been described already: Test Options – see section 6.8.3.1 ARFCN Lists – see section 6.8.3.2 RXLEV Threshold – see section 6.8.3.3 Advanced – see section 6.8.3.4 6.8.5.2 Running The Test Before running the test, ensure that a connection is established to the nanoBTS and that the configuration for the tests has been completed.
Figure 64 - BCCH Channel Usage Zoom 6.8.6 BCCH Information Test In this test the nanoBTS decodes the system information messages that are being broadcast on a set of channels and reports the values of attributes such as location area code, cell id, and BSIC, as well as measuring RXLEV and RXQUAL. This takes about 15 seconds per channel, because of the repetition rate at which the relevant system information messages are transmitted.
The BCCH Information test can be tailored to provide only certain information from the BCCH decode (the default is to show all information). To do this, select the BCCH Information tab as shown in Figure 65. Figure 65 - BCCH Information, BCCH Info Type Control Apply a BCCH Information Type RXLEV RXQUAL Freq Error & Quality Frame Offset © ip.access Ltd COMPANY CONFIDENTIAL Description If ticked, the settings of the other controls will be used.
Control Frame Number Offset BSIC Cell Global Identity BA List – SysInfo 2 BA List – SysInfo 2-bis BA List – SysInfo 2-ter Cell Allocation List © ip.access Ltd COMPANY CONFIDENTIAL Description If ticked, the measured Frame Number Offset will be reported. The Frame Number Offset is measured in units of a whole GSM frame, and is an unsigned 32 bit integer, which does not exceed 2715647 (2715648 being the number of frames in a hyperframe 51*26*2048).
6.8.6.2 Running The Test To run the test, click on the “Start Test” button at the bottom of the main screen; note that the status bar at the bottom of the screen indicates that the test is running. Following a short period of time, a graphical representation of the network band will be shown, as seen in Figure 66. By hovering the mouse icon over the top of a single ARFCN, decoded BCCH information will be displayed.
6.8.7 Frequency Synchronisation Test The Frequency Synchronisation test uses the nanoBTS’s NWL downlink receiver to monitor one or more GSM RF channels, and if suitable BCCH carriers are found, measure the frequency error of the local oscillator relative to the measured references. The user can choose whether the frequency errors should be combined or reported separately in the event that more than one BCCH carrier is found.
6.8.7.1 Test Configuration Some of the tabs on the Configure Test dialog box for the Frequency Synchronisation test have been described already: Test Options – see section 6.8.3.1 ARFCN Lists – see section 6.8.3.2 RXLEV Threshold – see section 6.8.3.3 Advanced – see section 6.8.3.4 Selecting the Freq Sync Options tab allows you to view and change settings that are specific to the Frequency Synchronisation test, as shown in Figure 68 below. Figure 68 - Freq Sync Options properties window © ip.
Control Apply Frequency Sync Options Frequency Quality Threshold Flags - List Flags - Set © ip.access Ltd COMPANY CONFIDENTIAL Description If ticked, the settings of the other controls will be used.

While the test is running the message pane in the lower part of the window will display “Test Running – Frequency Synchronisation”. While the nanoBTS is in this mode it is not possible to do anything else with it until the test is complete except end the test by selecting the Stop Test button. Once the test is complete the message pane will display “Test finished”.
6.8.8 Beacon Transmit Test The Beacon Transmit test is used so that the RF transmission from a nanoBTS can be measured without the nanoBTS having to be connected to a BSC. This is likely to be particularly useful during initial installation, when the BSC (or the communications link to the BSC) may not yet be available.
6.8.8.1 Test Settings Selecting the Beacon Information tab allows you to view and change the settings shown in Figure 71. Figure 71 - Transmit Beacon Properties Control ARFCN NCC BCC Absolute Power Description Determines the RF channel on which the beacon is to be transmitted. This must be a valid ARFCN for the Frequency Band selected at the top of the Network Listen window. The Network Colour Code which should be transmitted on the Synchronisation Channel. The valid range is 0..7.
6.8.8.2 Running The Test When all of the settings are completed start the test by clicking on the Start Test button.

6.9 Using BTS Installer via a proxy In some network configurations, BTS Installer is not on the same network as the nanoBTSs and is unable to access them directly. There are two optional system components called the Primary OML Proxy and Secondary OML Proxy that may be run on the BSC platform, and in appropriate network configurations these will forward requests from BTS Installer to the nanoBTSs and route replies from the nanoBTSs to BTS Installer.
• When running automatic configuration via a BTS Installer Proxy, performance may be lower than that achieved with a direct connection between BTS Installer and the nanoBTS.
6.9.2 Starting BTS Installer from Config Manager To start BTS Installer from Config Manager, select a Baseband Transceiver, BTS, Site, the Sites collection, or the BSS, and then choose the Launch BTS Installer command either from the context menu as shown or from the toolbar button with the spanner icon. BTS Installer will start in proxy mode, expecting that the one or both of the proxies is running on the BSC platform, and will be pre-loaded with all the nanoBTS at or beneath the selected managed object.
supply the Unit IDs and are not suitable for starting BTS Installer for use with a Primary OML Proxy. Note that BTS Installer may also be started in direct (non-proxy) mode with some IP addresses and optionally Unit IDs of nanoBTS on the command line, and these will be pre-loaded and will appear in the BTS Status list. © ip.access Ltd COMPANY CONFIDENTIAL CENG0336_XE_nanoBTS_Installation_and_Test_Manual.
6.10 Connecting to a nanoBTS via SSL BTS Installer is capable, when not operating in proxy mode, of connecting to a nanoBTS using an authenticated encrypted SSL (secure sockets layer) connection. 6.10.1 Enabling secure connections A number of conditions must be satisfied before an SSL connection can be set up. Firstly BTS Installer must be correctly installed: • • • • The user must be operating in a territory to which it is possible to export the cryptographic technology used.
Then, BTS Installer will only attempt to make SSL connections if this is selected in the Options dialog: • Optional or Mandatory must be selected. If all is well with the installation and configuration of BTS Installer then the status bar will indicate that security is possible and will display a closed padlock: or depending on the “Connect to BTSs using SSL” option selected.
