1. INSTALLATION

1.1 - I NTRODUCTION This paragraph explains how to install and set up SAGEM-LINK F-H radio links.

The main topics covered are:

• Unpacking the Equipment

• IDU installation

• Antenna installation

• ODU installation

• IDU to ODU coaxial cable installation

• Connecting IDU to external equipment

• Powering up the system

1.2 - U NPACKING THE EQUIPMENT

Verify that the items received are compliant with the packing list.If any part of the equipment is damaged, contact SAGEM Communications for repair orreplacement instructions.

The IDU and ODU are packaged in two separate boxes. In addition, the optional items arepackaged in a separate container.

The IDU box contains the IDU equipped with one or two modems (one for 1+0 systems, two for1+1 systems), the power supply cable and a CD-ROM including the user manual and the Pilotsoftware.

The ODU box contains the ODU only.

Whenever possible, save case and shipping material, in case the equipment has to be returned.


11/134


12/134


Alternative antennas to those specified by Sagem Communications may be used, but they must meetthe following requirements:

• Minimum gain to achieve adequate link margin,• Radiation Pattern Envelope compliant to the network and country regulations• Mechanical characteristics to meet specific site requirements (wind and frost resistance)

Note : With some antennas, a pressurizing system is required. It is essential to observe themanufacturer's recommendations:

installation and connection of a pressurizing system if the antenna is connected to the ODUwith a waveguide;

use pressurization windows and seals to protect waveguide connections.

1.4.1 - Antenna mountIn most cases, the antenna mounts consist of tubular poles (diameter 88.9 to 114 mm).

If the antenna is installed on towers using another type of structure (e.g., square-section tower),special mounting kits must be used for this support.

The following precautions must always be taken:

- Allow enough clearance ( ± 10°) about the alignment axis. Leave also adequate space aroundthe ODU to allow easy mounting/dismantling.

- Make sure that nothing obstructs the link between the two antennas, even partially,

- Install a lightning rod (Franklin) and earthing.

Note : If there is an existing lightning rod, make sure that the ODU installation site is coveredby the lightning protection cone.

- Misalignment under extreme weather conditions must not exceed ± 20 min angle in elevationand azimuth.

The antenna mount may be secured in different ways depending on the antenna installation sitetype and environment:

- Mounting pole secured to the HEA section with back-plates or clips each side of the HRAsection,

- Mounting pole secured to a concrete base plate with threaded rods embedded in the base.

- Wall-mounted staff (attached using dowels or back-plates with threaded rods),

- Antenna mount secured directly to a tower tube (diameter 88.9 or 114 mm).

1.4.2 - Antenna Installation

Refer to the antenna manufacturer's instructions.


13/134


1.5 - ODU INSTALLATION

Depending on the configuration and on the antenna type, there are several ODU mountingpossibilities:

1.5.1 - 1+0 Configuration wi th i ntegrated antenna

The ODU is directly attached to the antenna with 4 latches. It is connected to the IDU by a singlecoaxial cable terminated with N connectors.

Figure 1.2 - ODU SAGEM-LINK F-H with integrated antenna

Setting the polarization:

For antennas with a circular waveguide interface (7 GHz, 8 GHz, 32 GHz or 38 GHz), polarizationsetting depends only on the ODU position. For vertical polarization, make sure that the arrow onthe ODU cover is vertical, for horizontal polarization, turn the ODU 90 degrees.

Horizontal polarizationVertical polarization

Figure 1.3 - Polarization setting in 1+0 configuration


14/134


If the integrated antenna has a rectangular waveguide interface (6 GHz, 11 GHz, 13 GHz, 15GHz, 18 GHz, 23 GHz or 26 GHz), then the choice of polarization depends on the antennasource position. Note that in this case, the large side of the waveguides, antenna side, and theODU must coincide.For vertical polarization, the large side of the waveguide must be in horizontal position. ODU side,the arrow at the back of the box must be in vertical position.

For horizontal polarization, the large side of the waveguide must be in vertical position and thearrow on the ODU must be in horizontal position.

1.5.2 - 1+0 Confi guration wi th pole mount and s tandard antenna

For standard antennas (i.e. large diameter), the ODU is mounted on a pole with a specificmounting kit and connected to the antenna with a standard rectangular flex guide.

In this case, polarization depends on the antenna source position (vertical polarization is obtainedwhen the large side of the antenna waveguide is horizontal).

Figure 1.4 - ODU SAGEM-LINK F-H mounted on pole

1.5.3 - "Hot standby" 1+1 configuration with coupler and integrated antenna

In this configuration, the coupler is attached on the integrated antenna with four latches. TwoODUs are mounted each side of the coupler with four latches. Depending on the type of coupler,the ODUs are mounted differently. Refer to the instructions marked on the coupler.

Each ODU is connected to its modem by a coaxial cable. As in most cases the coupler is not symmetrical, it is important to identify which ODU isconnected to the main position, and which ODU is connected to protection (standby) position.The main and standby ODU positions are indicated on the coupler.


15/134


Whatever the polarization, the coupler is always mounted in the same position (the ODUs mustbe vertical).

The IDU has two modems connected to ODUs operating at the same frequency. The standbytransmitter is configured automatically by the software in "Mute" position.

Vertical polarization Horizontal polarization

Figure 1.6 - Polarization setti ng on 1+1 coupler

1.5.4 - 1+1 hot standby configuration with remote mounted coupler and standardantenna

The coupler is attached on the remote mount and connected to the standard antenna by arectangular flex waveguide.The two ODUs are mounted vertically each side of the coupler, in compliance with theinstructions shown on the coupler. Each ODU is connected to its modem with a coaxial cable.Polarization setting is done antenna side.


16/134


It is also necessary to identify ODU cables (Main or Standby) with labels.


1.5.5 - 1+1 space diversity conf iguration with 2 antennas

This configuration is similar to "hot standby" except that the ODUs are not coupled to the sameantenna: they are located at different positions, each connected to its own antenna.

This configuration is possible with integrated or standard antennas.


1.5.6 - 1+1 frequency diversi ty conf iguration with remote mounts and dualpolari zed antenna

In this configuration, each ODU is remote mounted on a pole and connected to an antennaaccess with a flex guide. It is important to identify the cables of the ODU mounted in verticalpolarization (main) and that mounted in horizontal polarization (standby).

The IDU has two modems connected to ODUs operating at the two different frequencies. The twotransmitters transmit permanently.

1.6 - I NSTALLING THE IDU TO ODU COAXIAL C ABLE

Two types of cable are recommended: RG8/X (1/4") for lengths less than or equal to 80 m, andRG8/U (3/8") for length less than or equal to 230 m. Andrew LDF4-50A cable can be used forlengths up to 600 m. Other cables may be used, but must be compatible as regards outdoor use(resistance to UV), losses, shielding (double or triple braid) and characteristics impedance (50Ohm, N male straight connectors at each end).

Only connectors recommended by the cable manufacturer should be used. These connectorsmust be assembled in compliance with the manufacturer's recommendations.

Since the Modem ODU access is a TNC type connector, an optional RG223/U Type stub cableequipped with a 50 ohm angled male TNC connector at one end and a 50 ohm straight female Nconnector at the other must be inserted between the cable connecting the ODU and the modem;this cable can be ordered from SAGEM Communications (see Table 1.2 - Cable References forSAGEM-LINK F-H) .

Self-vulcanizing tape is wound around the connectors to make them water-tight.

Note: Cables must be installed in compliance with the national and local regulations of theinstallation site.Special precautions are necessary when installing cables to prevent possible damage bylightning (regular grounding).

In 1+1 configuration, it is important to distinguish between the cable connected to the main ODUand that connected to the standby ODU. If the cables are not labelled, it is necessary to perform aresistance check to identify each cable.


17/134


Disconnect the cable IDU side and short circuit the connector main ODU side (the standby ODUconnector being in open circuit). Measure the resistance of the two cables IDU side using amultimeter. The cable to be connected on the main ODU is that with the lower resistance (nowidentify the cables ODU and IDU side with a label, sticker, etc.).Before reconnecting the IDU cables, disconnect the short circuit ODU side. Clean the connectorsif necessary and connect the cables on each ODU.

Cable Grounding

Good lightning protection is provided by grounding the antenna cable at several points. A cablegrounding kit is available on option.

The number of grounding points required mainly depends on the cable length.Good protection is achieved with:

• A grounding kit on the cable as close as possible to the ODU• A grounding kit on the cable at the building entrance• A grounding kit on the cable at the bottom of the pylon• A grounding kit every 50 meters

The screen displays the management routes already defined with their characteristics: Hops: 1, 2, 3… Path to move from one machine to another.

IP address: IP address of the recipient (equipment or subnet).

Delay (ms): return time.

Unit. size: Maximum size of the IP packet that can reach the remote equipment.

Choice "8": Factory settings

This command is used to restore the default factory settings.

Note : this command is only available from release R1.2

These settings will also be applied on the remote equipment, making sure that:

- the IP address of the remote equipment is in the same network as that of the local equipment (notmandatory but recommended)- the IP address of the Ethernet interface for the remote equipment does not belong to the same networkas that of the local equipment.

321


34/134


The principle of equipment IP addressing is described in paragraph 4.6.1 -. Depending on the softwarerelease, the routing tables may be static (R1.1) or dynamic (R1.2 and higher). In this case, the RIPand OSPF protocols can be implemented in order to simplify network management configuration.

2.3 - P ILOT SOFTWARE AND IP CONNECTIVITY

2.3.1 - Installing the Pilo t software

The Pilot allows the user to:

• View local and remote terminal configurations

• Set and change parameters on local and remote terminals

• Monitor RSL, BER and alarms

• Download and activate a new software version

Double click on the IDU address to start the Pilot session; by default, the main Pilot screen is displayed in"View Only" mode.

Click on the "Login" button to enter the default password: " 2345 " for a " Super User " level.

2.4 - L INK PRELIMINARY CONFIGURATION

2.4.1 - Setting the parameters of each IDU

The preliminary configuration of each IDU must be carried out separately at each end of the link. Oncethe link is established, virtually all the parameters can be checked from the local terminal.

The parameters of the local and remote terminals must be compatible.In order of priority, the first essential parameters to configure before establishing the link are for eachIDU:

• Channel transmit frequency

• Modulation type, radio channel and capacity

• Link ID code• Transmission power; the Automatic Transmit Power Control (ATPC) function must be inhibited

at this stage ("OFF" position on the Pilot screen)

Note : When powering up for the first time (factory output setting), the transmitter is in "MUTE" position,in order to avoid transmitting signals at a frequency which could disturb neighbouring links.

The transmitter should be kept in mute position until the transmit frequency, modulation and capacityare properly configured.

When the link is not established, the Pilot screen indicates "NO REMOTE RADIO" on the right side ofthe screen (see below).

View Only: read only mode

Click here to log in


38/134


This screen will display the local terminal parameters on the left of the screen and the remote terminalparameters on the right when the link is established.

The radio channel, modulation, capacity, Ethernet bandwidth and interleaver status are displayed atthe top of the screen. The confirm/cancel modification request is also displayed in this bar: " Confirm "or "Cancel ".

The IDU part of the screen is used to define the site name, configuration type, link ID code and todisplay the bit error rate (BER) for a given counting period (1 min, 15 min or 24 h).

The Channel 1 part indicates the received signal level and the reception BER; it is used to configurethe transmit frequency and transmit power values, ATPC activation and Mute function.

The equipment LEDs and the 3 programmable relays status are also displayed on the Pilot. Inaddition, the "Shelf view" button is used to display the front panel of the equipment managed.

If you are logged on as a "Super User", you can change the terminal configuration with the buttons.Each button provides access to a specific parameter. Note that only one change at a time is allowed.

With the transmitter still in "Mute" and the ATPC "OFF", configure the following parameters:

• Channel transmit frequency Move the cursor along the Tx Freq rule , or click on the left or right button, thenvalidate by clicking on "Confirm" in the top toolbar.Use the arrows to change the frequency in steps of 250 kHz. Moving the cursor in the middlechanges the frequency in steps of 7 MHz.

• Modulation, radio channel and capacity parameters

Double click on the top bar, the following screen is

displayed

The "Interleaver" configuration is described in § 3.8 - .

• Link IDThe link ID code is used to avoid demodulating data from another neighbouring link using thesame frequency which could disturb the receiver. Link ID Codes of the local and remoteterminals must be the same. This code consists of a number from 1 to 255 chosen by thecustomer.

• Transmit power The transmitter's "Mute" position is set to "OFF".

Adjust the transmit power value as planned in the design calculation, keeping ATPC "OFF".

Move the cursor along the Tx Power rule , or click on the left or right button, thenvalidate.Use the arrows to change the power in steps of 0.5 dB. Moving the cursor in the middlechanges the power in steps of 2.5 dB.

Important : To avoid saturating the transmitter, the Pilot software automatically preventspower values greater than t he maximum allowed for the current modu lation. Refer to thevalues
