2 Commissioning software overview

The Nokia MetroSite EDGE Base Station is configured in the network with Nokia
SiteWizard software for GSM and/or GSM/EDGE with Nokia SiteWizard
software, version 3.0 or later. BTS commissioning is done locally at the BTS
using SiteWizard’s BTS Manager software.

The appropriate CX software packages for the BTS’s configuration are loaded to
the master TRX at the factory or from the BSC. For EDGE transmission, CX 3.2
or later is required. These software packages are downloaded locally using Nokia
BTS Manager during commissioning, or remotely from the BSC.

After commissioning, the BTS is normally managed remotely from the OSS via
the BSC, although O&M tasks can also be done locally with BTS Manager.

2.1 Nokia SiteWizard 3.0

3 Preparing for commissioning

Before starting BTS commissioning, complete the following procedure.

Preparing for commissioning:

1. Check that the Abis cables are connected on the BTS.

Commissioning can be performed without the BSC connection (Abis cables
disconnected, for example). For more information, see Step 7 in the
commissioning procedure in Chapter 5.

2. Check that the Nokia MetroSite EDGE Base Station is powered up.

3. Connect the Nokia BTS Manager PC to the BTS’s LMP port. See
Appendix A for a description of the LMP cable.

4. Check that you have the required Site IDs (optional) and transmission
capacity tables.

BTS SW is loaded to the BTS by the manufacturer at the factory. There is no need
to locally load SW to the BTS before commissioning. If the BTS SW is different
from the SW at the BSC, it will be loaded automatically to the BTS during the
commissioning procedure.

4 Getting started with BTS Manager

This chapter gives instructions on how to install, set up and obtain on-line help on
Nokia BTS Manager software. It is assumed that the user knows how to use the
Windows operating system.

When Nokia BTS Manager is installed and set up, the BTS is commissioned by
starting Commissioning Wizard, as described in Chapter 5 of this document.

4.1 Installing Nokia BTS Manager

Nokia BTS Manager is installed on a laptop PC which is connected to the BTS
via the LMP connector on the interface unit.

The installation program creates a Nokia BTS Manager icon on the Windows
desktop and defines the software’s parameters.

For more information on software installation and the system requirements of the
laptop PC, see the Nokia Site Wizard Software Release Binder or the instructions
on the CD-ROM sleeve.

4.2 Setting up Nokia BTS Manager

Start Nokia BTS Manager as follows:

1. Make sure that the BTS Manager laptop is connected to the LMP connector
on the interface unit of the BTS.

2. Double-click the BTS Manager icon on the desktop.

3. Enter the Nokia BTS Manager password. If the password checking option
has not been turned on and it is required, go to FILE | OPTIONS in Nokia
BTS Manager to set up a password (Windows 95/98 environment only).

Commissioning

5 Commissioning Wizard process

Commissioning is done with Nokia BTS Manager’s Commissioning Wizard.

It is assumed here that the site has been created at the BSC (LAPD links created
and PCM port active). If the site is newly created, the BCF is in the ‘locked’ state.

5.1 How to use Commissioning Wizard

Commissioning Wizard guides you through the commissioning process with a
series of wizard pages. Each wizard page contains data entry fields or paths to
dialogue boxes for data entry. When the settings on each wizard page are set up
according to your requirements, move to the next stage of the wizard with the
NEXT command, as described in the procedure in Section 5.2.

If you need to go back and change settings while in the wizard, click BACK. To
stop the commissioning without saving any of the settings, click CANCEL. Click
the HELP button on any wizard page to get a pop-up Help window.

When starting commissioning, the BCF object in the Supervision - Equipment
View window displays the ‘BCF is commissioning’ symbol (see Figure 3). You
can also check the operational state of the BCF by moving the mouse pointer over
the BCF symbol in the Supervision - Equipment View window, clicking the right
mouse button and selecting the BCF Properties command.

5.2 Commissioning with Commissioning Wizard

To commission the BTS, follow the steps in the procedure below. You will be
asked to refer to other sections in this document for some operations in the
procedure, after which you should return to this main procedure.

Commissioning with Commissioning Wizard:

1. Start Nokia BTS Manager 3.0 on your laptop.

2. In BTS Manager, choose the COMMISSIONING | WIZARD command
from the main menu. The BTS Commissioning Wizard window appears.

3. Commissioning can only be done with a non-commissioned BTS. If the
BTS is already commissioned, select ‘Undo Commissioning’ and NEXT in
the BTS Commissioning Wizard window (this would be the only option
available in Commissioning Wizard). The BTS will be un-commissioned
and the ‘Manual Commissioning’ option will then appear in the BTS
Commissioning Wizard window.

To commission the BTS, select ‘Manual Commissioning’ in the BTS
Commissioning Wizard window and click NEXT (see Figure 4).

Note

Figure 7. Opening Traffic Manager from Commissioning Wizard

When you have completed the allocation in Traffic Manager and you return
to this wizard page, the BACK button is disabled because the transmission
configuration has been loaded to the BTS and the transmission connection
is established between the BTS and the BSC. If the connection fails, see
Chapter 11 of this document, ‘Troubleshooting and fault reporting’.

If you need to change any of the parameters you have specified prior to this
point, click CANCEL, run the ‘Undo Commissioning’ procedure and then
re-commission the BTS with the correct parameters.

Commissioning Wizard will automatically proceed to the next wizard page after
you have allocated the incoming Abis capacity and the BTS is ready for testing.

7. Depending on the status of the Abis connection, proceed either from Abis
connected or Abis not connected.

1. Abis connected:

Commissioning Wizard process

DN999099 © Nokia Corporation Draft 33 (78)
Issue 4-0 en Nokia Proprietary and Confidential

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
loading will take from 5 to 20 minutes, depending on the OMUSIG
link speed. If no SW loading takes place, the process will take about
10 seconds.

If SW loading takes place, the BCF is in the ‘SW loading’ state
during the SW loading operation. This information is shown on the
BTS Events list. When the SW loading from the BSC is completed,
the BCF is reset automatically. This means that the Supervision -
Equipment View disappears for a few seconds, but after the BTS has
started normally, the commissioning procedure continues
automatically.

After the SW checking and/or loading, the BSC sends the
configuration data to the BTS and the BCF enters the ‘Configuring’
state. It can take up to five minutes for the oven oscillator to warm
up after the BTS is powered on. The BTS Events window displays a
message when the oven oscillator is ready.

When the BTS is ready for testing, the Wizard automatically
proceeds to the next wizard page and the BSC runs automatic tests
on the Abis link and on each TRX installed in the BTS.

The Abis loop test will take about two minutes (all channels of all
TRXs are tested).

2. Abis not connected:

If the establishment of the BTS/BSC connection does not succeed
(Abis cables are not connected, for example), the BCF remains in the
‘Waiting for LAPD’ state. If you now click NEXT, the Wizard
displays a message (see Figure 8). The message also asks you if you
want to give the ‘Use Current’ command. If you click YES in the
dialogue box, the BTS starts to use the BTS SW in the master TRX
memory and the Wizard proceeds to the BTS Test Reporting wizard
page after TRX and BCF achieve the ‘Configuring’ state. If you
click NO in the dialogue box, the BCF remains in the ‘Waiting for
LAPD’ state until you connect the Abis cables.

Caution

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

8. If Abis is connected, the BTS Test Reporting wizard page displays the test
results (see Figure 9). Check the results in the ‘Events’ list.

Whether or not Abis is connected, BTS Manager requests HW reports from
the BTS. The ‘Events’ list will display any alarms 10 seconds after the BCF
has entered the ‘Supervisory’ state. The NEXT button becomes enabled at
this point.

Click NEXT to proceed to EAC input settings.

you have specified or automatically to your laptop’s Windows desktop.
Commissioning Wizard is now closed. See Chapter 10 for more details on
the Commissioning report.

If there is a need to route transmission capacity, the cross-connections have to be
created manually. See Chapter 9 for instructions on how to create the cross­connections.

For maintenance purposes, in the case of a BTS with only one TRX, it is
recommended to make a back-up copy of the time-slot allocation settings using
the Traffic Manager’s export function (see Section 6).

At this point you should check the Alarms window in the main Nokia BTS
Manager - Supervision window for possible alarms generated during
commissioning. Figure 13 shows an example of a major alarm, which must
be cleared. The minor alarms (cover open and MMI connected) are cleared
when the BTS commissioning procedure is completed.

For alarm descriptions, see Nokia MetroSite EDGE Base Station Alarm
Descriptions.

For future maintenance purposes, it is recommended that you export the cross­connection information of the FXC E1/T1 transmission unit to a file. For
instructions, see the section called ‘Replacing the transmission unit’ in Nokia
MetroSite EDGE Base Station Maintenance.

Nokia Proprietary and Confidential Issue 4-0 en

Note

With an FXC transmission unit, the cross-connections to this BTS are created
automatically after the capacity has been set and approved.

The capacity to be used is defined by selecting its signal type (TCHs, TRXSIG,
OMUSIG, TRXSIG on TCHs or OMUSIG/TRXSIG) and by reserving required
time slots and bits. The signal types are explained in more detail in Section 6.2.

In the case of 1.5 MB links (T1), the Traffic Manager automatically reduces the
number of time-slot rows in the table to 24.

With EDGE transmission, the dynamic Abis feature is used to improve the
efficient the use of transmission resources. This requires allocation of the EGPRS
dynamic Abis pool (EDAP) between the available EDGE TRXs in a BTS or BTS
chain.

6.1 Allocating transmission capacity

Transmission allocation capacity and dynamic Abis are both allocated from the
Traffic Manager window.

6.1.1 Allocating Abis transmission capacity

Allocate Abis transmission capacity as follows:

1. Select the line interface used (Port 1 - Port 16, depending on the
transmission unit). With an FC E1/T1 transmission card, the only possible
option is Port 1.

2. Click the TCHs button and then click in a cell in the ‘Abis TS Allocation
for this BTS’ table to allocate time-slots. Repeat this step to allocate
transmission capacity to all TRXs in the BTS. See Figure 16 for an example
of allocating transmission capacity to a TRX.

Note

4. If EDGE transmission is not required, proceed directly to Section 6.1.4 to

complete the Abis transmission allocation.

For EDGE transmission, proceed to Section 6.1.3 to allocate EDGE TRXs
to the dynamic Abis pool.

For chained BTS transmission allocation, proceed to Section 6.1.2.

6.1.2 Allocating transmission capacity for chaining

The chaining feature is available for BTSs which have been loaded with CX 3.0
software or later. Two or three Nokia MetroSite EDGE BTSs can be chained
together as one BCF object.

For example, a chain of two BTSs might contain five TRXs, as seen in the
example of BTS Manager’s Supervision - Equipment View window in Figure 2.
The transmission capacity can be allocated between the TRXs in the chained
BTSs, as described in the procedure below. BTS Manager is connected to the
master BTS in the chain.

Before beginning a site expansion, the site must be locked from the BSC or NMS
with BCF lock.

You can check if the site has been locked by connecting a BTS Manager laptop
to the master BTS in the chain, starting BTS Manager and checking TRX
PROPERTIES in the Supervision - Equipment View window (right-click with the
mouse over a TRX in the window).

Note

Allocate transmission capacity for chaining as follows:

If the FXC type transmission unit replaced an FC type transmission unit during a
BTS upgrade for chaining, or if CX 3.0 software (or later) is not loaded at the
BTS, the site must be uncommissioned and then re-commissioned before
allocating transmission capacity for the BTS chain.

With BTS Manager, uncommission the master BTS by selecting
COMMISSIONING | WIZARD from the main menu and selecting the ‘Undo
Commissioning’ button. Make sure that CX 3.0 or later is loaded at the BSC or
NMS and start Commissioning Wizard again, as described earlier in this manual.

1. Select the line interface used (Port 1 - Port 16, depending on the
transmission unit). An FXC type transmission unit is required for chaining.

2. Click the TCHs button and then click in a cell in the ‘Abis TS Allocation
for this BTS’ table to allocate time-slots to a TRX. Repeat this step to
allocate transmission capacity to all TRXs in the BTS chain (up to 12 TRXs
are possible in a chained configuration).

In the example shown in Figure 18, there are five TRXs in two BTS
cabinets. TRXs 1, 2, and 3 are in the first BTS and TRXs 5 and 6 are in the
second BTS in the chain.

From here onwards, you can choose one of three alternative ways to
proceed.

Alternative 1.

Click the TRXSIG button and then click the first bit in a time-slot in the
Abis allocation table. Select the link speed from the pop-up menu. Repeat

6.1.3 Allocating for EDGE dynamic Abis transmission

Dynamic Abis uses the EGPRS dynamic Abis pool (EDAP) to efficiently allocate
transmission resources for the higher EDGE data rates.

EDAP resources are shared between EDGE TRXs in a single BTS, chained BTSs,
or cross-connected BTSs. The available TRXs are allocated in Traffic Manager
from the EDAP command.

Allocate TRXs to the EDAP as follows:

1. Select the incoming line interface port according to the transmission unit
used and then click the EDAP button.

2. Select the start time-slot by clicking with the mouse. Drag the mouse to the
end time-slot and release. The EDAP Properties dialogue box is opened

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

If you want to modify the allocation table at this point, you have to first delete
prior allocations. Click the right mouse button on the cell to be modified and
delete either one signal allocation, all signal allocations of a particular type or
delete all allocations for the selected port.

If you want to modify the allocations after you click OK in the Traffic Manager,
you must first run ‘Undo Commissioning’ in the BTS Commissioning Wizard.

When the link capacity restricts normal signal allocation, you can use the
‘TRXSIG on TCHs’ and combined ‘OMUSIG/ TRXSIG1’ signal types.

6.2 Signal types

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, 32, or 64 Kbit/s). If a combined
OMUSIG/TRXSIG1 is used, the allocation of the OMUSIG is disabled.

OMUSIG/TRXSIG1

The BTS can have one combined OMUSIG/TRXSIG1 which allocates 2, 4, or 8
bits in one time-slot depending on the link speed used (16, 32, or 64 Kbit/s). When
a compressed Abis time-slot allocation is used, the OMUSIG/TRXSIG1 can be
located in radio time-slots 1 - 4 (starting from bit 1), which means that it overlaps
the TCHs which are reserved for TRX 1.

TCHs

The BTS must be allocated at least as many TCHs as there are TRXs installed in
it (1 - 4). Each TCH allocates two 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 4 in the order they are defined.

Commissioning

52 (78) © Nokia Corporation Draft DN999099

Nokia Proprietary and Confidential Issue 4-0 en

TRXSIG

The BTS must be allocated at least as many TRXSIGs as there are TRXs installed
in it (1 - 4). 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 4 in the order they are entered.

TRXSIG on TCHs

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

9 Cross-connections

Cross-connections need to be created for routing transmission capacity to the
other BTSs in a chain or loop transmission topology.

Cross-connections are only supported with the FXC type transmission units.

The BTS has to be commissioned before creating the cross-connections.

9.1 Creating cross-connections

Cross-connections are created with the E1/T1 Manager (Transmission Unit
Manager) application in Nokia BTS Manager.

Cross-connections define how signals are routed from an FXC transmission unit
to another transmission unit. Cross-connections are created into inactive banks.
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.

Creating bi-directional cross-connections:

1. Open E1/T1 Manager by selecting TRANSMISSION | OPEN on the BTS

Manager menu bar. The E1/T1 Manager is launched and the BTS Manager
session terminates.

2. Select CONFIGURATION | CROSS-CONNECTIONS on the E1/T1

Manager menu bar. The Cross-connections window opens, as shown in
Figure 34.

11 Troubleshooting and fault reporting

In the case of a failure in the commissioning procedure, check if there is a
corresponding alarm in the Alarms window in Nokia BTS Manager (see the BTS
Alarm Descriptions document in the Nokia MetroSite EDGE Base Station SW
release binder). Also, you may check the cause of a failure from the
commissioning report.

The commissioning procedure may fail for the following reasons:

• The Abis cables are not properly connected (the transmission unit LED will

not show green).

• The pre-configuration failed at the BSC. For example, the BCF and TRX

objects were not created.

• PCM time-slot allocations are incorrect. The parameters at the BSC and on

the site are not the same. Run ‘Undo Commissioning’ and redo
commissioning with the correct parameters.

• The PCM port is not activated at the BSC.

• The transmission path is incorrectly configured. Check cross-connections.

• The CRC and/or interface mode settings for the E1/T1 card are incorrect.

In BTS Manager, choose LIF SETTINGS on the TRANSMISSION menu,
and check that the ‘CRC in Use’ and ‘Interface Mode’ settings are correct
for the interface.

Before starting to re-commission the BTS, first run the ‘Undo Commissioning’
procedure. If the Commissioning Wizard has stopped, click CANCEL to abort the
commissioning procedure.

Report all damages, failures or faults to Nokia using the Failure Report Form
provided by Customer Services (CS).
