Figure 8 below illustrates the correct cabling of the Ethernet and TIB
cables:
Figure 8 - Ethernet and TIB cabling
4.6.3 Ethernet
Each 139/140/178 nanoBTS must be connected to an Ethernet switch or hub via either
a 109 ip.access single power inserter or 126 ip.access Powered Ethernet Switch.
Refer to CENG0033 for details of the power supply connections. The 165 EDGE
nanoBTS may use either the above power options or a separate 48V DC power supply
available from ip.access.
4.6.4 Timing Interface Bus (TIB) – Multi-TRX only
The Timing Interface Bus (TIB) is used to provide clock and signaling between the
nanoBTS when operating in a Multi-TRX configuration.
The TIB OUT from the Master TRX must be connected to the TIB IN of the slave TRX.
This in turn has its TIB OUT connected to the next TRX in the chain. See Figure 9.
The location of each nanoBTS is shown on the installation floor plan produced at the
network planning stage. The network wiring must be complete before the nanoBTS
can be installed and commissioned. The nanoBTS should be placed on a wall at or
above head height or on a ceiling. Unless explicitly stated otherwise, the following
procedure is common for both 139/140 and 165 hardware variants.
Remove the nanoBTS from the bracket by sliding the removal tool over the central fin
between the bracket and the body of the unit to disengage the locking spring, slide
bracket to separate it from the main body of the unit. The tool may be inserted from the
top or bottom of the nanoBTS
Figure 12 - nanoBTS Bracket Removal
Position the bracket on the wall and mark the position of the four screw holes. The top
of the bracket MUST be positioned uppermost. Ensure that the bracket is level and
sufficient clearance is maintained to allow the unit to be located on the bracket (at
least 80mm from the bracket to the top of wall and 120mm from the side of the bracket
to a side wall). See the diagram below, Figure 13 - Fixing the wall bracket.
80mm min
120mm min
Figure 13 - Fixing the wall bracket
Drill the four holes in the positions marked previously and insert wall plugs (if required)
and fix the mounting bracket securely to the wall. The bracket is designed to allow the
nanoBTS unit to be mounted with the connections at the bottom of the unit.
Slide the nanoBTS onto the bracket and ensure that the retaining spring engages into
the indent at the rear of the unit.
When fixing to a ceiling or a sloping wall the same fixing process and clearances
should be observed as for fixing to a wall (at least 80mm from the bracket to the top of
wall and 120mm from the side of the bracket to a side wall). On a sloping surface the
top of the bracket MUST be uppermost. Once the unit has been attached to the
bracket the outer cover MUST be removed to expose the cooling vanes, as shown in
Figure 15 - Ceiling Mounted nanoBTS
Figure 15 - Ceiling Mounted nanoBTS
4.7.1 Mounting Multi-TRX nanoBTS
When the nanoBTS are to be installed in a Multi-TRX configuration, then each TRX
should be installed in a similar orientation but not closer than 30cm to each other.
A further specific constraint is that the TIB cables must be <1.5m and a 1.5mm
2
Chassis Bond cable must also be connected between each TRX with a length not
exceeding that of the TIB cable.
4.7.2 Mounting Multi-TRX 165 nanoBTS
The 165 (EDGE) BTS may be installed in a stacked two-TRX configuration. See
Annex A - Drawing 165#018 for details. The procedure for mounting a stacked twoTRX configuration is as follows:
• Fit the first wall bracket to the wall in the desired position
NOTE: The nanoBTS must be powered on for a minimum of 24 hours prior to final
frequency calibration. It is recommended that during installation an initial, local
calibration is made following a powered on time of > 10 minutes followed by a final
operational calibration after 24 hours power on time.
NOTE: If the nanoBTS is used in a Multi-TRX configuration, then the TIB OUT must be
disconnected from each nanoBTS in the chain prior to calibration and reconnected
afterwards. Only the Master TRX should be calibrated.
• Using BTSInstaller, select the nanoBTS that is to be calibrated and then click
on the “Listen” button in the “BTS Status” pane.
• Select the frequency band to match that of the nanoBTS to be installed.
• Click on the “Connect” button, this will cause the nanoBTS TRX to power up.
The status LED will flash green when completed.
• Click on the “Channel Usage” tab and then click on the “Start Test” button.
• When completed click on the “BCCH Channel Usage” tab and then click on the
“Start Test” button.
• When completed, click on the “Frequency Synchronisation” tab.
• Select “Configure Test”
• Select the “Freq Sync Options” tab and then click on the “Apply Frequency
Synch Options” and change the Option to “Adjust The Clock To Correct The
Reported Errors” then click “OK”
• Click on the “Start Test” button.
Once the test completes then the calibration is completed and the procedure should
be repeated for all installed nanoBTS before reconnecting the TIB cables.
Following the 24-hour period, the Frequency Calibration procedure should be
performed as per the Operations procedure – Ref {2}

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.
This document covers only those aspects of nanoBTS installation that involve using
BTS Installer. For full details of how to install a nanoBTS, please refer to [CENG0336].
6.1.2 Related Documents
[CENG0336] CENG0336, “nanoBTS Installation and Test Manual”, ip.access (latest
issue)
6.2 Capabilities
BTS Installer contains a collection of related tools that enable you to:
• Perform initial installation and manual configuration of nanoBTSs.
• Upgrade and reconfigure nanoBTSs.
• Perform Network Listen tests.
These include all the operations necessary to install and configure a nanoBTS to the
stage where it will connect correctly to a BSC, from which point its telecommunications
behaviour can be configured using management software.
Before a nanoBTS can connect to a BSC:
• It must have an IP address, and other IP configuration parameters must be set.
• It must have a Unit ID, as this is what it uses to identify itself to the BSC.
• It must have various non-volatile attributes configured; as a minimum it must
know where to find the BSC before it can connect to it.
At various times, either during initial installation of a nanoBTS or after it has already
been operational for a while, it may be necessary to:
• Change the nanoBTS’ IP configuration, Unit ID or non-volatile attributes.
• Download a new version of software to the nanoBTS.
• Perform various diagnostic operations on the nanoBTS, such as querying its
current configuration.
A nanoBTS can optionally communicate with the BSC via a secure SSL link. To
configure it to do so it is necessary to:
• 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. This will respond to requests from nanoBTSs only, so
should co-exist with any other DHCP servers that are present on the same network.
In addition BTS Installer contains a Network Listen tool that enables you to control a
nanoBTS to:
• Listen to its GSM band and report on received signal strength and BCCH
details for each ARFCN.
• Correct its clock by reference to the signals from other cells.
• Transmit a beacon signal that can be listened to and measured by other
nanoBTSs, which can be useful in ensuring adequate coverage of an area.
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. Detaile
aspects of the user interface will be found in later sections.
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.
There are several ways in which BTS Installer can get to know about a nanoBTS, ie
ways in which a nanoBTS can be added to the BTS Database:
• Information about the nanoBTS can be loaded from a configuration file (see
section 6.3.4).
• The Find co
nanoBTSs that BTS Installer was able to locate on the local LAN (these
nanoBTSs must already have valid IP configurations for the Find command to
work).
• The New command will create a BTS Database entry full of default values; the
user must edit some values in this entry before it is useful, and in particular
must enter either a MAC address or an IP address or a Unit ID before BTS
Installer will be able to identify the nanoBTS to which the entry relates.
• The IP address and optionally the Unit ID of the nanoBTS can be specified on
the command line when BTS Installer is started.
BTS Database entries are deleted:
• When the Delete command is used.
• When a new configuration file is loaded.
• When BTS Installer is shut down.
A BTS Database entry can be edited:
• Using the Edit command.
• Indirectly using the Defaults command, which affects all BTS Database entries
that don’t have more specific values.
None of BTS Installer’s tools, including the DHCP server, will operate on a nanoBTS
for which there is no BTS Database entry.
mmand will create BTS Database entries for one or more
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.
The configuration phases are, in the order in which they are run in automatic mode:
• Setting the nanoBTS’ IP configuration using the built-in DHCP server.
• Setting the nanoBTS’ Unit ID.
• Setting the nanoBTS’ non-volatile attributes.
• Downloading a file to the nanoBTS.
Each phase can be enabled or disabled separately for each nanoBTS. The download
file can download any one of: software; a certificate; a certificate revocation list, but
can only download one file at a time.
The BTS Status section of the user interface gives a quick reference to which phases
are enabled for which nanoBTSs: this is indicated by the colour code in the columns
headed respectively DHCP, UNIT Id, NV Attr, D’LOAD – grey indicates that this phase
is disabled for this nanoBTS, any other colour indicates that this phase is enabled for
this nanoBTS. Status colours other than grey are accompanied either by explanatory
text, or by a symbol (Grey = no symbol, Red = cross, Yellow = question mark, Red =
tick).
6.3.3 Modes of Operation
BTS Installer has a variety of different modes of operation, to suit different
circumstances and requirements.
6.3.3.1 Manual and Automatic Operation
BTS Installer has an automatic mode of operation, in which it will apply all enabled
phases of configuration to all known nanoBTSs in parallel, and when it has finished it
will produce a summary in the log window and log file and will display in the BTS
Status window which phases of configuration for which nanoBTSs have succeeded
and which have failed.
This automatic mode of operation is initiated by pressing the Auto button in the BTS
Database Log section of the user interface.
BTS Installer also has a manual mode of operation, in which the user performs just
one operation at a time on just one nanoBTS at a time, and has immediate feedback
as to the success or failure of the operation.
The various manual operations are available from pressing the Action button in the
BTS Status section of the user interface.
Some example scenarios are:
• A number of operating nanoBTSs are to have their software upgraded.
Automatic mode is used to download the new version of software to all of them
at once.
• 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.
There is a special “Unknown BTS” mode of operation in which the BTS Database
contains just one special entry. This special entry acts as if it had a wildcard MAC
address, and the DHCP server will recognise any nanoBTS that asks for an IP
configuration.
IN THIS MODE THERE IS NOTHING IN BTS Installer TO STOP THE
CONFIGURATION OF ANY nanoBTS THAT IS CONNECTED TO THE
NETWORK FROM BEING CHANGED.
This special mode of operation is designed to be used when only one nanoBTS at a
time is connected to the computer running BTS Installer, usually on a tiny private
network, perhaps just a crossover cable. It bypasses the normal safeguards that BTS
Installer uses to ensure that it makes configuration changes only to BTSs that are
identified as those that the user has specified.
There is no way to create this special BTS Database entry from the graphical user
interface; it must be loaded from a configuration file. There is no particular indication to
the user that BTS Installer is in Unknown BTS Mode, except that the Find and New
buttons in the BTS Status section of the user interface are disabled.
6.3.3.3 Proxy and Direct Operation
There are various network configurations in which BTS Installer may be used, and the
general design of the IP network configuration is outside the scope of this document.
In some network configurations BTS Installer is on the same network as the
nanoBTSs, in that there is an IP route from BTS Installer to the nanoBTSs. In such
configurations BTS Installer can communicate directly with the nanoBTSs in direct connection mode.
There are two different types of direct connection that BTS Installer can make to a
nanoBTS: a normal TCP connection or a secure SSL connection.
In other network configurations BTS Installer and the nanoBTSs are on different
networks, and there is no IP routing between the two. Typically in this scenario the
BSC will be multihomed, and will have an interface to each network but will not route
IP packets between the two networks. An optional system component, the BTS
Installer Proxy, can be installed as part of the BSC, and will forward requests from
BTS Installer to the nanoBTSs and return the replies. In such configurations BTS
Installer communicates with the nanoBTSs in proxy mode.
There are two different types of proxy that might be present on a BSC: a Primary OML
Proxy and a Secondary OML Proxy. Which can be used depends on the network
configuration.
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.
The configuration file is a text file which can be created with any text editor and which
contains definitions for:
• default values for BTS attributes
• the nanoBTSs to be operated on
• attributes to be set for the BTSs
• the DHCP server’s IP address pool.
It is not necessary to create a configuration file for most uses of BTS Installer, as
almost all necessary information can be entered via the graphical user interface. The
only exception is that a BTS Database entry for the “Unknown BTS” cannot be entered
via the GUI and can only be entered via the configuration file.
At any point it is possible to save the current state of the BTS Database and IP
address pool to a configuration file; this can be done even if no configuration file has
been loaded and all data has been entered via the GUI. This allows you to
• enter configuration information via the GUI
• save this to a new configuration file
• load the configuration file in a later run of BTS Installer.
In other words, you can use BTS Installer itself to create a configuration file for later
use, instead of using a text editor.
Section 6.10 gives details of the syntax of the configuration file.
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.java.sun.com
6.4.1.1 Microsoft Windows
To install BTS Installer run the supplied .msi file and follow the instructions on screen.
If it is desired to use BTS Installer to make secure (SSL) connections to nanoBTSs
then
• the Aladdin eToken run time environment must be installed, which in turn
requires that the computer is running either Windows 2000 SP4 or Windows
XP or later
• the eToken, which is a hardware device which contains a certificate and private
key for BTS Installer, must be plugged into a USB port.
6.4.1.2 Other Platforms
).
Details of installing BTS Installer on platforms other than Microsoft Windows are
beyond the scope of this document. However in most cases copying the file
BtsInstaller.jar to a suitable directory will be adequate. On platforms other than
Windows there is no support for making SSL connections to the nanoBTS.
6.4.2 Starting BTS Installer
6.4.2.1 From Config Manager
BTS Installer can be started from Config Manager, in which case it will be prepopulated with some nanoBTSs selected in Config Manager and will operate in proxy
mode. See section 6.9.2 for details.
6.4.2.2 Microsoft
BTS Installer can be started by double clicking the desktop item or by selecting the
menu entry in the normal way.
6.4.2.3 Other Platforms
Details of starting BTS Installer on platforms other than Microsoft Windows are beyond
the scope of this document. However on platforms with a command line interface a
command like:
