The ordering practice will change so that the product codes, comprimising of both
a main unit and plug-in units, are not used any longer. Now the main unit
(T55240.01) and the needed number of plug-in units are ordered with seperate
codes. For example, to get a 12 x 2M 1+0 configuration, place an order for one
main unit and three 4 x 2M plug-in units. For 16 x 2M 1+0 you have to order a
main unit a suitable upgrade kit (T55246.4x).
The capacity of Nokia MetroHopper is fixed to 4 x 2 Mbit/s.

1About this document
This document gives task-oriented instructions for the commissioning of Nokia
MetroHopper Radio with FC RRI or FXC RRI indoor unit. Commissioning and
maintenance actions are carried out using the Nokia BTS Manager or Nokia
MetroHub Manager software included in the Nokia SiteWizard CD-ROM.
This document describes only outdoor unit -related settings and functions. To
commission Nokia MetroHopper with FC RRI or FXC RRI you need also Nokia
MetroSite GSM BTS User Manual or Nokia MetroHub User Manual which
describe all node-level and RRI-related settings and functions.
For information about installing FC RRI and FXC RRI transmission units, please
refer to Nokia MetroSite GSM BTS User Manual or Nokia MetroHub User
Manual. The instructions for installing the MetroHopper outdoor unit are found
in Outdoor Unit Installation document in this manual. Read the Product
Description document before commissioning Nokia MetroHopper. Product
Description serves as a reference document and explains all relevant terms.

2Commissioning Nokia MetroHopper
This chapter describes the commissioning process of the Nokia MetroHopper
Radio. All commissioning tasks are performed with Nokia BTS Manager in case
the radio is used with Nokia MetroSite GSM BTS or with Nokia MetroHub
Manager in case the radio is used with Nokia MetroHub.
2.1 Precautions
The following pre-requisites must be fulfilled before starting the commissioning:
• you have already either
• the FC RRI unit logically installed in the BTS
or
• the FXC RRI unit(s) logically installed in the BTS or the
transmission node.
• the outdoor unit is installed and aligned in accordance with the instructions
given in this manual.
• you already have a connection to the network element with the node
manager.
Please refer to Nokia MetroSite GSM BTS User Manual or Nokia MetroHub User
Manual for more instructions.

2.2 Commissioning with Nokia BTS Manager
Nokia BTS Manager contains a Commissioning Wizard, which facilitates the
base station commissioning process. Run the Commissioning Wizard as
instructed in Nokia MetroSite GSM BTS User Manual. Fill in all the required
settings. Whenever an FC RRI or FXC RRI unit is included in the BTS
configuration, a specific Radio Link Settings page is displayed during the wizard
sequence. By clicking the Radio hop(s) button on the page you can launch a
Radio Wizard sequence during which you can check or set any required outdoor
unit related settings.
Commissioning with the Radio Wizard
1. The first page in the Radio Wizard sequence displays the type of the indoor
unit (FC RRI or FXC RRI) and the outdoor units (MetroHopper or
FlexiHopper) connected to each Flexbus interface.
Select the In use option for each Flexbus interface you want to use. At least
one outdoor unit must be connected and one Flexbus in use before you can
proceed to the next page.
The radio capacity of Nokia MetroHopper is fixed to 4 x 2 Mbit/s.
If the transmission unit is FC RRI, only Flexbus 1 settings are displayed.

Figure 1. Flexbus settings page
2. The MetroHopper General Settings page is displayed next. On this page,
you can select the settings for the outdoor unit connected to the Flexbus 1
interface.
• Hop Mode: one of the terminals forming a radio hop must be
configured as the master and the other end as the slave. The
hierarchy is decided in the network planning phase.
• Temporary Hop ID: the master and the slave must have the same
temporary hop ID. When the commissioning is completed, this is
automatically changed to a unique hop ID.
• Channel Selection: you can choose either Manual or Automatic
channel selection. When you click Next, the corresponding channel
selection page will open.
• If you choose Manual channel selection, select the desired
channel. You can also click Measure to measure the
interference level on the selected channels and then select the
best available channel.
• If you choose Automatic channel selection, mark the channels
among which the channel is to be selected. The software
automatically measures the interference levels on each
channel, and selects the best one.

3. If the transmission unit in use is FXC RRI, define the settings for the
Flexbus interface 2 and the connected outdoor unit as described above. If
the transmission unit is FC RRI, only one Flexbus is available and you can
proceed to step 4 directly.
4. When you have entered all the required settings, Summary of
Commissioning Settings page is displayed. It contains all the settings you
have defined for the radio(s). Check that the settings are correct and click
Next to send the settings to the node. You can also go back in case you want
to adjust the settings on previous pages.
5. Monitoring Hop page displays the status of the hops during and after the
commissioning. If the commissioning is successful, the status becomes
Ready.
The status of the hop will not be Ready before also the other end of the hop is
commissioned successfully. Thus, the status of the terminal that is commissioned
first will have the status Commissioning until the far-end terminal is
commissioned.

Click Report to see a more detailed commissioning report for each outdoor
unit. The commissioning report contains, for example, the measured
interference level of the selected channel, and the fading margin
measurement.
Click Next to return to the Nokia BTS Manager Commissioning Wizard.
2.3 Commissioning with Nokia MetroHub Manager
Nokia MetroHub Manager contains Commissioning Wizard, which facilitates the
commissioning process. Commissioning Wizard will first ask you to accept the
selected site configuration file (.SDF) and to send the node settings to the node.
In case radio link equipment is installed, you can monitor the radio hops in the
Check and Fine-tune Hops page. The Commissioning Wizard will
automatically draw a commissioning report which is displayed on the last page of
the wizard sequence.
In case you will later install new radios, you can commission the equipment by
launching the Radio Wizard from the FXC RRI menu. The procedure is exactly
the same as described in the previous section.
FC RRI is not compatible with Nokia MetroHub.
2.4 Configuring identifications and settings
This section describes how to view or change outdoor unit related identifications
or settings with Nokia BTS Manager or Nokia MetroHub Manager. When you are
using Nokia BTS Manager, all Nokia MetroHopper related identifications and
settings are accessed through the Transmission menu. In case you are using
Nokia MetroHub Manager, these are found under the FXC RRI menu.
For simplicity, both the Transmission menu of Nokia BTS Manager and the FXC
RRI menu of Nokia MetroHub Manager are henceforth referred to as
Transmission / FXC RRI.

2.5 Verifying commissioning
It is recommended to monitor the hop for at least half an hour after all settings
have been made at both ends of the hop. Reset the statistics and the error counters
and let the hop operate for half an hour (or longer, if desired). After the time has
passed, check that the signal quality statistics and the error counters do not show
any undesired values (see Section 3.2.).
If the signal quality is OK (unavailability time = 0) and there are no unexpected
alarms, the commissioning of the hop is complete. If there occurs any
unavailability time during the monitoring, repeat the monitoring.

3Maintaining Nokia MetroHopper
This chapter contains the following information:
• preventive maintenance
• performance monitoring
• replacing or removing equipment.
3.1 Preventive maintenance
Maintenance of the radio includes measurements which do not interfere with the
communication. Measurements which do interfere with the communication can
also be conducted when the radio is in operation, provided that the measurements
are performed at a time when there is no traffic or the traffic can be rerouted. With
the Nokia Network Management System (NMS), service measurements can be
performed in a centralised manner for the entire network without having to move
physically from station to station. However, any measurements performed with
external measuring instruments must be conducted locally.
Record the measurements so that they can be compared with earlier results and
used to detect significant changes in the results. Store the measurement records at
the location where the measurements are conducted, that is, the records of
centralised measurements in the central monitoring room, and the records of
external measurements at the equipment station.
3.2 Performance monitoring
The indoor units record information regarding the performance of the network
element.
The performance information is divided into three areas:
Commissioning and Maintenance
18 (42) © Nokia Networks Oy DN99611394
Issue2-0en
• measurements
• error counters
• signal quality statistics.
Each of these is available from the Measurements or Statistics menu in the node
manager, in some cases, from the toolbar.
The measurement and error counter windows both display information about the
performance of the network element and its current operating condition. The
statistics are collected for the signal.
3.2.1 Measurements
The Interface Measurements window, which is opened from Transmission /
FXC RRI →Measurements, displays selected information about the network
element. This information is in the form of, for example, bit error rates and
voltage or power levels recorded from particular units inside the functional
entities of the network element.
Monitoring measurements
These values are automatically refreshed according to the time interval that you
can enter into the Auto Refresh field. If the refresh rate is set to 0 seconds, the
refresh is done only once. The values can also be manually refreshed by clicking
the Refresh button.
3.2.2 Error counters
Error counters in the network element record the number of times that an error
had occurred in a particular unit or functional entity.
Click Transmission / FXC RRI →Statistics to open the Statistics dialog box,
which displays the error counters for the selected interface.
All error counters in the network element can be reset to zero by selecting the
corresponding Reset radio button in the Statistics dialog box.
3.2.3 Reading statistics
The statistics that the network element records for signal quality are kept to ITU-
T recommendation G.826. These values are available for 2M platform interfaces
of FXC RRI (last 16 measurements).
The following statistics are recorded:
Maintaining Nokia MetroHopper
DN99611394 © Nokia Networks Oy 19 (42)
Issue 2-0 en
To see the signal quality counters, click Transmission / FXC RRI →Statistics
on the menu. This will open the Statistics dialog box, in which you can choose
the interface for which the statistics will be displayed.
It is possible to reset all the signal quality statistics by selecting the corresponding
Reset radio button in the Statistics dialog box.
3.3 Using loopbacks
Each unit contains several loopback points, which you can set manually to test the
node. These loopbacks are accessed by clicking Transmission / FXC RRI →
Interface loops on the menu.
The loopback status can change without the user changing it, for example, if the
time-out has been reached. Because of this, the Loopback window has its own
private status bar, which shows the last time the status of the loopbacks was
checked, and how long till the next refresh. You can set the refresh value by
selecting Manage →Service Interface on the menu and entering the required
value on the Time-outs tab.

Caution
Note
Switch the Flexbus OU power supply off with the node manager before replacing
a faulty outdoor unit.
If the units to be removed or replaced carry important traffic, reroute the traffic
before starting the work. The removal or replacement of equipment cuts traffic.
To replace or remove the Nokia MetroHopper outdoor unit:
1. Set the OU to Receiving only transmitter mode (see Section ). This ensures
that the radio will not transmit accidentally in case it is reinstalled.
2. Uninstall the OU logically by clicking with the right mouse button the unit
in the Equipment window and selecting the command Uninstall.
3. Switch the power to the OU off. The power can be turned off with the node
manager. Click Transmission / FXC RRI →Settings →Unit and clear
the OU power setting of the appropriate Flexbus interface.
4. Disconnect the cabling.
5. Remove the unit. Follow the instructions found in the OU Installation part
of this manual.
6. Install a new unit (if applicable). Follow the instructions found in the OU
Installation part of this manual.
If the replacement of the radio is done carefully, the alignment will not be
affected.
After replacing the outdoor unit, run the Radio Wizard to make the link
operational.

AIS 2M
Severity: Major Unit/SB type:
1) Flexbus channel
2) Platform interface
Fault code: 66 Consequence:
Meaning: Alarm signal is received, the received signal has no framing and it is all ones.
Instructions: The signal is cut somewhere in the network and AIS replacement has taken place. Follow the 2M
signal in the network to find out the place where AIS replacement has been done. This link is usually faulty or
has configuration errors. Other alarms may cause this alarm because of AIS switching in the receiving direction
as shown in the Consequence field of some alarms.
Cancelling:
Alarm signal received
Severity: Critical Unit/SB type: Flexbus
Fault code: 64 Consequence: AIS is connected to all received Flexbus channels. This will cause
AIS 2 Mbit/s alarm to all used platform interfaces that are connected to the alarming
Flexbus interface.
Meaning: OU has lost the frame lock and it has replaced the frame with a pseudo frame to ensure IU - OU
communication.
Instructions: The signal may be faded in the radio path. In this case the OU has the loss of incoming radio signal
alarm. If this is not active in the OU, check the radios at both ends of the hop. They must have the right
configuration (frequency, interleaving and TX power on). Check also that the same capacity has been selected
for both ends of the hop.
Cancelling: If the radio signal is faded it will come back when the fading stops. If the OU is FlexiHopper, check
the maximum TX power setting. If a stronger TX power is allowed, it will withstand fading better.

Protective grounding
DN99611437 © Nokia Networks Oy 13 (14)
Issue 2-0 en
Note
4Protective grounding
To ensure safe installation conditions for both personnel and equipment, the
grounding of and equipment station must be done before installing the equipment.
The purpose of protective grounding is to keep the potential of the equipment at
the same level as the potential of the surrounding ground. This prevents
generation of dangerous voltages between the equipment and the ground.
Because of the high locations of the radio and base station equipment, equipment
stations are particularly suspectible to lightning strokes.
The grounding should be done according to the rules and regulations issued by
the local authorities. Refer also to site level documentation, if applicable.
To ensure the operation of the equipment, all equipment of an equipment station
must be connected to the same grounding potential.
Follow the grounding instructions presented in the Nokia MetroHopper Outdoor
Unit Installation document.
Ground the sheath of the Flexbus cable between the indoor unit and the outdoor
unit at approximately 50 m intervals. Ground the sheath also at the inlet to the
equipment space. National regulations may require grounding every 20 m.

5.1 Grounding
The radio section must be connected to an external grounding electrode
immediately after installation. The grounding wire is of type 16 mm2 Cu.
To connect the grounding wire:
1. Peel the tip of the grounding wire (15 mm).
2. Connect the grounding wire to the grounding clamp of the outdoor unit and
tighten the M6 screw.
3. Connect the other end of the grounding wire to the general grounding wire
or bar of the installation pole.
Make sure that general grounding is performed according to regulations issued by
the local authorities.
5.2 Connecting the Flexbus cable
A clamp-type (watertight) straight TNC connector fitted into, for example, RG−
223 cable can be used to connect the IU and the OU. Leave the cable slack enough
to allow the outdoor unit to be turned during the alignment. It is advisable to label
the cables (for example with the hop ID) in order to facilitate identification later.
In case the cables are completed on site, protect the connectors from water with
adhesive tape or shrink-on wrapping. The ready-made cables have a shrink-wrap
protection.
If the cable is already connected to the indoor unit, make sure the Flexbus OU
power supply is switched off before connecting the cable to the outdoor unit.
Power can be switched off using the manager software.

To connect the IU - OU Flexbus cable:
1. Connect the TNC connector of the Flexbus cable to the FB+ interface.
Tighten theconnector manually (0.5 Nm).
2. Tie the cable to the installation pole with cable ties or with special holders
(FIMO, for example).
If the Flexbus cable is taken to the radio but left unplugged, protect the connector.
Ground the sheath of the Flexbus cable between the indoor unit and the outdoor
unit at approximately 50 m intervals. Ground the sheath also at the inlet to the
equipment space. National regulations may require grounding every 20 m.
5.3 Connecting the synchronisation cable
If synchronisation is required, remove the connector cap and connect the
synchronisation cable to Sync-connector. See Product Description for further
details on planning the synchronisation.
5.4 Closing the connector cover
After connecting all the required cables, close the connector cover and tighten the
screw.
