1. INSTALLATION

1.1 - INTRODUCTION 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 - UNPACKING 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 or replacement instructions. The IDU and ODU are packaged in two separate boxes. In addition, the optional items are packaged in a separate container. The IDU box contains the IDU equipped with one or two modems (one for 1+0 systems, two for 1+1 systems), the power supply cable and a CD-ROM including the user manual and the Pilot software. The ODU box contains the ODU only. Whenever possible, save case and shipping material, in case the equipment has to be returned.


1.3 - IDU INSTALLATION To install the IDU in a 19-inch rack: •

Attach the IDU in the 19-inch rack using 6x12 stainless steel hex screws. This attachment grounds the IDU to the earth. Faston socket

Figure 1.1 - IDU installation •

An additional grounding is possible by the use of a Faston plug (left side of the IDU). Use a 6 mm section yellow/green cable (minimum length required).

2

Note: When more than one IDU are to be mounted in the rack, it is recommended to keep a gap of 1 unit between two IDUs.

1.4 - ANTENNA INSTALLATION Three types of antenna are available for SAGEM-LINK F-H radios: •

Integrated antenna with SAGEM-LINK F-H mechanical interface (0.3 m, 0.6 m, 0.9 m, 1.2 m or 1.8 m diameter). The ODU is directly attached on the antenna using latches. In 1+1 configuration, a coupler can be attached directly to the integrated antenna, the ODUs being attached in the same way on the coupler.

•

External antenna with standard rectangular waveguide interface , which is connected to the SAGEM-LINK F-H ODU with a flex guide.

•

External dual polarized antenna (frequency diversity configuration) connected by flex guides to two ODUs.

Antennas models depend on the frequency bands: 6 GHz (6L) → 5.9 - 6.4 GHz • 6 GHz (6H)→ 6.4 - 7.1 GHz • 7 GHz → 7.1 - 7.7 GHz • 8 GHz → 7.7 - 8.5 GHz • 11 GHz → 10.7 - 11.7 GHz • 13 GHz → 12.75 - 13.25 GHz • 15 GHz → 14.4 - 15.35 GHz • 18 GHz → 17.7 - 19.7 GHz • 23 GHz → 21.2 - 23.6 GHz • 26 GHz → 24.5 - 26.5 GHz • 32 GHz → 31.8 - 33.4 GHz • 38 GHz → 37 - 39.5 GHz •


Alternative antennas to those specified by Sagem Communications may be used, but they must meet the 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 the manufacturer's recommendations: 



installation and connection of a pressurizing system if the antenna is connected to the ODU with a waveguide; use pressurization windows and seals to protect waveguide connections.

1.4.1 - Antenna mount In 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 around the 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 covered by the lightning protection cone. - Misalignment under extreme weather conditions must not exceed and azimuth.

±

20 min angle in elevation

The antenna mount may be secured in different ways depending on the antenna installation site type and environment: - Mounting pole secured to the HEA section with back-plates or clips each side of the HRA section, - 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 t hreaded 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.


1.5 - ODU INSTALLATION Depending on the configuration and on the antenna type, there are several ODU mounting possibilities:

1.5.1 - 1+0 Configuration with integrated antenna The ODU is directly attached to the antenna with 4 latches. It is connected to the IDU by a single coaxial 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), polarization setting depends only on the ODU position. For vertical polarization, make sure that the arrow on the ODU cover is vertical, for horizontal polarization, turn the ODU 90 degrees.

Vertical polarization

Horizontal polarization

Figure 1.3 - Polarization setting in 1+0 configuration


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

1.5.2 - 1+0 Configuration with pole mount and standard antenna For standard antennas (i.e. large diameter), the ODU is mounted on a pole with a specific mounting 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 obtained when 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. Two ODUs are mounted each side of the coupler with four latches. Depending on the type of coupler, the ODUs are mounted differently. Refer to t he 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 is connected to the main position, and which ODU is connected to protection (standby) position. The main and standby ODU positions are indicated on the coupler.


Whatever the polarization, the coupler is always mounted in the same position (the ODUs must be vertical). The IDU has two modems connected to ODUs operating at the same frequency. The standby transmitter is configured automatically by the software in "Mute" position.

Figure 1.6 - Polarization setting on 1+1 coupler

1.5.4 - 1+1 hot standby configuration with remote mounted coupler and standard antenna The coupler is attached on the remote mount and connected to the standard antenna by a rectangular flex waveguide. The two ODUs are mounted vertically each side of the coupler, in compliance with the instructions shown on the coupler. Each ODU is connected to its modem with a coaxial cable. Polarization setting is done antenna side.


It is also necessary to identify ODU cables (Main or Standby) with labels. The IDU has two modems connected to ODUs operating at the same frequency. The standby transmitter is configured automatically by the software in "Mute" position.

1.5.5 - 1+1 space diversity configuration with 2 antennas This configuration is similar to "hot standby" except that the ODUs are not coupled to the same antenna: they are located at different positions, each connected to its own antenna. This configuration is possible with integrated or standard antennas. The IDU has two modems connected to ODUs operating at the same frequency. The standby transmitter is configured automatically by the software in "Mute" position.

1.5.6 - 1+1 frequency diversity configuration with remote mounts and dual polarized antenna In this configuration, each ODU is remote mounted on a pole and connected to an antenna access with a flex guide. It is important to identify the cables of the ODU mounted in vertical polarization (main) and that mounted in horizontal polarization (standby). The IDU has two modems connected to ODUs operating at the two different frequencies. The two transmitters transmit permanently.

1.6 - INSTALLING THE IDU TO ODU COAXIAL CABLE Two types of cable are recommended: RG8/X (1/4") for lengths less than or equal to 80 m, and RG8/U (3/8") for length less than or equal to 230 m. Andrew LDF4-50A cable can be used for lengths 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 (50 Ohm, N male straight connectors at each end). Only connectors recommended by the cable manufacturer should be used. These connectors must 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 cable equipped with a 50 ohm angled male TNC connector at one end and a 50 ohm straight female N connector 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 for SAGEM-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 the installation site. Special precautions are necessary when installing cables to prevent possible damage by lightning (regular grounding). In 1+1 configuration, it is important to distinguish between the cable connected to the main ODU and that connected to the standby ODU. If the cables are not labelled, it is necessary to perform a resistance check to identify each cable.


Disconnect the cable IDU side and short circuit the connector main ODU side (the standby ODU connector being in open circuit). Measure the resistance of the two cables IDU side using a multimeter. The cable to be connected on the main ODU is that with the lower resistance (now identify the cables ODU and IDU side with a label, sticker, etc.). Before reconnecting the IDU cables, disconnect the short circuit ODU side. Clean the connectors if necessary and connect the cables on each ODU. Cable Grounding Good lightning protection is provided by grounding the antenna cable at several points. A cable grounding 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 •

2.2 - CONFIGURING EQUIPMENT IP ADDRESSES Connect the IDU serial port to a serial port on the PC with an RS-232 cable. Run Windows HyperTerminal: "Start/Programs/Accessories/Communications/HyperTerminal". Enter a name in the window which is displayed (e.g. SAGEM-LINK F-H), choose an icon for the connection then validate. In the next window choose the PC "COM" port which is connected to the equipment then validate. In the next window, set the following parameters: Bits per second: 19200 • Data bits: 8 • Parity: none • Stop bits: 1 • Flow control: none • Validate the settings and save the connection (Save command in the application File menu). The next you run Hyperterminal, simply choose the connection icon to connect to the equipment. Note: By default, the password is empty on first commissioning.


Validate, the following window appears:

To select a command, type the command number in the text zone " Choice ?" and press "ENTER" to validate.



Choice "1": Configuration of the equipment IP address.

The default IP address is 192.168.001.002. Enter the required IP address, keeping in mind that it must be different from that of the other equipment addresses and must be defined in a subnet different from that of the Ethernet interface. The IP address of the remote equipment will belong to the same network. Example: if the IP address of the local equipment is 192.168.113.141, that of the remote equipment will be 192.168.113.xxx with xxx not equal to 141.


You are prompted to reboot the equipment. You can reboot later, without affecting the traffic, after entering the settings. Error message "Equipment address is mandatory": you must enter the equipment address



Choice "2": default gateway configuration

The default Gateway IP address is 000.000.000.000. You are prompted to reboot the equipment. You can reboot later, without affecting the traffic, after entering the settings.



Choice "3": Ethernet interface configuration.

The Ethernet interface characteristics are displayed and can be modified: "Interface State": use of the interface: 0 (Interface off) or 1 (Interface on). "IP Address" "Subnet mask" "Route Protocol": 0 (None), 1 (RIP) or 2 (OSPF)


The IP address of the Ethernet interface for the equipment connected to the management PC must belong to the same network and have the same subnet mask as the PC IP address. The IP address of the Ethernet interface for the remote equipment must belong to a different network. Example:

management equipment address: 135.010.115.015 with a subnet mask of 255.255.255.0 The PC address must be 135.010.115.xxx with xxx not equal to 0, 255 or 015. The address of the remote equipment must belong to another network, e.g. 10.142.113.150.

These management Ethernet interfaces are available on the equipment accesses "Mgmt1" and "Mgmt2". You are prompted to reboot the equipment. You can reboot later, without affecting the traffic, after entering the settings. Choice "4": REBOOT the equipment. This command reboots the application immediately, restarting with the settings already stored in the equipment. Reboot takes place without affecting the traffic. 

Choice "5": Logout Setting finished, this command closes the current session. The session is closed automatically after several minutes with no activity (delay configurable from the manager). 

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


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

2.3 - PILOT SOFTWARE AND IP CONNECTIVITY 2.3.1 - Installing the Pilot 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

•

Perform installation and maintenance operations

•

Configure the network management interface

Insert the Pilot software CD-ROM into the drive. The installation software runs automatically if the drive has been configured in "Autorun" mode. Otherwise, run Windows explorer and double click on "setup.exe".

Once the software is installed, double click on the Pilot icon The following window appears:

The Pilot software is specific to this version of SAGEM-LINK and is not compatible with the previous versions.


2.3.2 - IP connectivity Connect an RJ45 Ethernet crossed cable between access "Mgmt1" or "Mgmt2" of the local IDU and the management network. Before starting a Pilot session, check the connectivity between the PC and the local IDU. Check that the IP address of the management PC belongs to the same network as that of the local IDU Ethernet interface, then check the connectivity with a ping of the IDU Ethernet address from the Windows DOS command prompt. Declare the route to reach the local IDU equipment IP address, then check the connectivity by pinging this address.


2.3.3 - Starting a Pilot session After checking the connectivity, start a Pilot session from the Session/Open session menu The local IDU address is entered in the following window

Click on Add to enter the local IDU address

Click on OK


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

View Only: read only mode Click on the "Login" button to enter the default password: "2345" for a "Super User " level.

2.4 - LINK 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. Once the 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 each IDU: •

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 capacity are properly configured. When the link is not established, the Pilot screen indicates "NO REMOTE RADIO" on the right side of the screen (see below).


IDU Equipment IP address

This screen will display the local terminal parameters on the left of the screen and the remote terminal parameters on the right when the link is established. The radio channel, modulation, capacity, Ethernet bandwidth and interleaver status are displayed at the 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 to display 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 configure the 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. In addition, 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, then validate 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 middle changes the frequency in steps of 7 MHz.

•

•

Link ID The link ID code is used to avoid demodulating data from another neighbouring link using the same frequency which could disturb the receiver. Link ID Codes of the local and remote terminals must be the same. This code consists of a number from 1 to 255 chosen by the customer. 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, then validate. Use the arrows to change the power in steps of 0.5 dB. Moving the cursor in the middle changes the power in steps of 2.5 dB. Important: To avoid saturating the transmitter, the Pilot software automatically prevents power values greater than the maximum allowed for the current modulation. Refer to the values in APPENDIX 1 § Transmission characteristics .

The local terminal is now correctly configured. Repeat the procedure for the remote terminal in order to establish the link.

2.4.2 - Antenna alignment Antenna alignment is performed with both terminals operating, in normal weather conditions. The received signal level (RSL) can be checked using the voltage available on the ODU BNC connector. A typical curve of RSL voltage against RSL at ODU input is given below. The RSL voltage is directly proportional to the RSL expressed in dBm.

Figure 2.1 - SAGEM-LINK F-H ODU RSL voltage Note: RSL is measured at ODU antenna port. For 1+1 configurations involving a coupler, the coupler losses must be taken into account to determine the RSL at antenna access. Optimum alignment is achieved when main antenna lobe is aligned with the remote antenna. During alignment, it is important to distinguish between the main lobe and the side lobes by rotating the antenna around the maximum RSL value. Note that there is around 25 dB difference between side lobes and main lobes (i.e. about 1.5 V on the RSL voltage).

Good alignment

Bad alignment Figure 2.2 - Antenna alignment


The expected RSL was determined during the link budget calculation. This level depends on the power of the remote terminal, the frequency, the antennas gain and the hop length. Antenna alignment is carried out on each antenna using the following procedure: 1- Check that the remote terminal transmitter is on, with the planned parameters (frequency, power, speed, modulation). Check that the ATCP is off and that the remote terminal power is such that the RSL does not exceed –20 dBm. 2- Remove the cap on the ODU BNC connector and connect a voltmeter. 3- Slowly rotate the antenna in the azimuth direction (horizontal) and find the maximum voltage. If the voltage is around 4.5 V, reduce the remote transmit power to avoid saturation. 4- Slowly rotate the antenna in the elevation direction (vertical) and find the maximum voltage. Record the measured voltage. 5- When the maximum voltage has been found, tighten all the bolts. Check that the voltage has not changed after tightening. Replace the protective cap on the BNC connector. 6- Compare the RSL obtained with the expected RSL. If the difference between the two values exceeds 5 dB, readjust antenna alignment and polarization setting and check that there are no obstacles on the radio path. In principle, if the parameters have been entered correctly and if the antennas have been aligned correctly, the link should be established (no screen with "NO REMOTE RADIO" message) and the main Pilot screen should display the remote terminal parameters. In 1+0 and 1+1 configuration, the typical screens are as follows:

Receive signal levels should be similar on both ends of the link (same transmit power).

Figure 2.3 - Main Pilot Screen for a 1+0 configuration

Note: If the parameters of the two terminals are correct, and if the main Pilot screen displays "NO REMOTE RADIO", the antennas will probably have to be realigned.


Figure 2.4 - Main Pilot Screen for a 1+1 configuration Note: There may still be some alarms at this stage. In case of "GE" or "tributary" alarm, check the access configuration and connections. connections. If there are other alarms, or if the link does not work, refer to the troubleshooting paragraph paragraph (§ 5 in this manual) Note any discrepancies in the Commissioning Form at the end of paragraph 2.

2.5 - TESTS AND MEASUREMENTS REQUIRED After installing and setting the link, check correct operation by performing the following tests and measurements: • • • • • • • •

Frequency Scan at ODU input Received Signal Level Gigabit Ethernet transmission test 2 Mbit/s channel test (optional) Wayside access test (optional) Alarm In/Out test (optional) 1+1 switching check (optional) BER measurement

Measurement equipment required: • • •

Gigabit Ethernet tester 2 Mbit/s bit error rate analyzer (optional) Digital multimeter

A SAGEM-LINK F-H Commissioning Form is provided at the end of paragraph 2 in order to record the results of the tests carried out together with any remarks made during installation and commissioning.


2.5.1 - Frequency Scan The Pilot software can be used to take an automatic measurement of the spectrum around the receive frequency without the need for external instruments. The measurement must be taken locally, successively at each end of the link. Measurement Measurement is carried out with the local transmitter off (the Pilot software automatically sets the local transmitter to "mute", to avoid sending signals which could disturb other receivers. After acquisition, the spectrum is displayed graphically. This measurement reveals the presence of any interferers. A record of this measurement is stored in the IDU flash memory and can be consulted afterwards using the Pilot or via the network management. management. In order to check interferer level at t he received frequency, frequency, the remote transmitter must be switched off during the test. The "Frequency scan" procedure is described in § 4.23 Note in the commissioning form the presence of any interferers at the received frequency as well as on the adjacent channels (first adjacent and second adjacent). Important: do not run a frequency scan from a remote site

2.5.2 - Receive signal level Under normal weather conditions, the receive signal level depends on the following parameters: •

Remote Transmit Power (tolerance: ± 2 dB)

•

Local and remote antenna gains (tolerance: ± 1 dB per antenna)

•

Free space path attenuation depending on hop length and frequency

•

Coupling and connection connection losses for a 1+1 system

Compare the actual received signal level displayed on the main screen of the Pilot software, with the expected signal level: The following tolerances must be taken into account: ± 2 dB for the transmit power • ± 1 dB for the gain of each antenna • ± 3 dB for the received level measurement displayed on the Pilot • ± 0.5 dB for 1+1 coupler losses • We see that in the worst case, for a 1+0 type system, the maximum uncertainty is ±7 dB (±2 ±1 ±1 ± 3): In practice, the typical uncertainty to be considered is ±5 dB. dB. So, if the difference between the receive level displayed by the Pilot and the receive level expected by the link budget calculation is within the tolerance ± 5 dB, the installation is considered to be correct. A difference of more than ± 5 dB, however, indicates a problem such as incorrect antenna alignment, alignment, a propagation problem or bad polarization on one of the two antennas. First check the antenna alignment and polarization. If the problem remains, refer to the troubleshooting guide in paragraph 5 and replace the defective element. Record the ODU RSL values of the link on the commissioning commissioning form.


2.5.3 - Giga Ethernet transmission test This test is carried out to check for correct transmission of Gigabit Ethernet signals. The test must be carried out on each port used. It is used to test Ethernet transmission transmission over the entire link. A Gigabit Ethernet tester is required to take the measurement. The measurement block diagram is given below:

Tx / Rx loopback Gigabit Ethernet tester

The Gigabit Ethernet tester is connected to a GE port of the local terminal. On the remote terminal, the corresponding GE output is looped back on the input (by a fibre in case of optical interface or an "RJ45 plug" in case of electrical interface). The "RJ45 plug" consists in connecting wires 1 and 3 together and wires 2 and 6 together. t ogether. The test consists in measuring the throughput according to RFC 2544 for long enough to check the quality of the link. The test will be declared positive is no packets are lost and if the throughput measured is not less than the limit specified. This limit depends mainly on the configuration: modulation, radio band and number of associated optional E1s. Choice of transmission configuration •

Define the configuration for each end of the link: modulation, radio channel, number of active E1 tributaries ( optional).


On the local IDU: The tester must be connected to the GE port to be tested. It is configured as follows: •

Number of Gigabit Ethernet ports to be considered: 1 ⇒ The Ethernet tester is connected to GE port #n of the IDU under test, where n = 1 or 2. ⇒ GE port #n of the IDU must be configured in "Enable" mode. ⇒ Configure the tester so that it takes into account the type of SFP module installed on the IDU: electrical or optical. If the operator uses optical SFP modules, auto negotiation must be activated on the tester.

•

Define a Unicast flow to be transmitted: ⇒ Define the size of this flow. Standard RFC2544 recommends the following sizes: 64, 128, 256, 512, 1024, 1280, 1518 bytes. SAGEM-LINK F-H also supports frame sizes of up to 1760 bytes. Choose one of these sizes.

•

Define the test duration.

•

The throughput defined by standard RFC2544 characterizes the maximum data rate that can be transmitted without losses. This parameter depends on the transmission configuration (see table in APPENDIX 2) and the associated Ethernet features (e.g. QoS).

•

Define a throughput (generally called ILOAD on an Ethernet tester) less than or equal to the throughput specified for the configuration defined.

•

The user can choose whether or not to activate radio shaping. When radio shaping is on, the switch can manage the quality of service. The throughput, however, is less than that observed without shaping. (about 6 % less, irrespective of the configuration).

On the remote IDU: •

Make the physical loopback on GE port #n of the remote equipment.

Choice of Ethernet configuration: Configure the equipment as follows: •

Configure each Ethernet port of the equipment as follows: ⇒ Topology: "Y shape" ⇒ Port mode: "Enable" for port #n being tested (local and remote equipment). ⇒ Jumbo mode: "Disable".


•

The user can choose whether or not to activate radio shaping

If the user configures "Traffic shaping mode" in "Enable" mode, the radio throughput allocated to the Ethernet transmissions is 94 % of the value displayed in the "Radio bandwidth" field. Refer to the table in APPENDIX 2. Set the "Traffic shaping bandwidth" field to 100 % if radio shaping is active.

•

Check that there are no SFP alarms (GE LEDs green)

•

Launch the tester script (frame loss test): check that no frames are lost.


2.5.4 - 2 Mbit/s tributary test (optional) These tests must be carried out on both terminals of the link. A 2 Mbit/s transmission analyzer is required, which must be set with the following parameters: • • • • •

BER test 2 Mbit/s Internal clock 15 PRBS: 2 -1. 120 Ohm balanced, or 75 Ohm unbalanced interface depending on IDU configuration.

All channels designed to transport traffic must be tested one by one: • • •

Click on one of the "TRIB" connectors Shelf view or use the menu: "Configuration / E1 Tributaries / Local" Check that the channel under test is configured in normal mode (N), in service (blank button) and no loopback (blank button). All other tributaries should be unconnected and configured as inverted (I)

•

There should be a "tributary" alarm, the "Trib" LED of the equipment and its image on the Pilot screen must be red.

•

Connect the transmission analyzer to the 2 Mbit/s input, respecting the impedance selected in the IDU. The tributary alarm should now be cleared.

•

Click on the "Loopback" button corresponding to the tributary under test. Select a remote loopback. See procedure in § 3.4 Check on the transmission analyzer that no errors occurred for one minute

• •

When the test is finished, disconnect the cable, change the alarm in invert mode (I) and remove the remote loopback.

•

Repeat this test on each 2 Mbit/s channel used on the site.

•

Record the results on the commissioning form


2.5.5 - Wayside test (optional) The same procedure is used to test the Wayside access and the main Gigabit Ethernet accesses. A 10/100BaseT Ethernet tester is required to perform this test. As when testing the GE ports, make a physical loopback on the remote terminal RJ45 access by connecting pins 1 and 3 together and 2 and 6 together. The test consists in checking that the transmission has no losses on this access at the specified throughput. Note: The throughout is the same irrespective of the configuration (modulation / radio channel). Tester configuration: • • • •

Number of Ethernet ports to be considered: 1 Configure the tester in 10/100 Mbps auto negotiated mode. Define a unicast flow of size n bytes. (64 ≤ n ≤ 1760). Depending on the size of the Ethernet frame to be transmitted, define an ILOAD less than or equal to the specified throughput in the following table, e.g.: ⇒ For a flow of 64 bytes, the maximum throughput is 1.25 Mb/s. ⇒ For a flow of 1518 bytes, the maximum throughput is 1 Mb/s

•

Check that there are no Wayside alarms on the equipment (Wayside LED green)

•

Start the test (frame loss): check that no frames are lost.

2.5.6 - Alarm relay test (optional) SAGEM-LINK F-H can manage 5 local external alarms and 5 remote external alarms (image of the 5 external alarms of the remote IDU). If some external alarms are to be managed, it is necessary first to configure them (see § 3.6 -). SAGEM-LINK F-H includes 3 fully programmable relay outputs. Internal or external alarms can be assigned to each relay. If alarm relays and/or external alarm inputs are used on the site, the tests described below must be carried out to check correct operation. These tests must be carried out on each terminal. Before starting the tests, check that no faults are displayed by the equipment. It is not possible to simulate all possible alarms without opening the equipment: for example, simulating a Tx frequency alarm would require opening the ODU and disturbing the transmission synthesizer phase loop. However some alarms can be simulated simply, without having to carry out any operations on the equipment. 2.5.6.1 Simulating an IDU Alarm An IDU alarm can be easily simulated by entering a wrong Link ID code in the local terminal. This wrong ID Code generates an IDU alarm, but does not affect the radio transmission. Apply the following procedure: • • • •

Switch off the local terminal power supply and disconnect the coaxial cable to the ODU Power up the IDU (ODU not connected) and change the Link ID Code of the local terminal Switch off the power supply of the local terminal and connect the ODU to the IDU Switch on the IDU Once the IDU is properly initialized an IDU alarm should be displayed: front panel "idu" LED, and its representation on the Pilot screen must be red.

Once the test is finished, do not forget to put back the correct Link ID code using the same procedure.


2.5.6.2 Simulating an ODU Alarm An ODU alarm can be generated by removing the cable to the ODU. Caution: switch off the power supply before disconnecting the cable. The equipment "ODU" LED and its image on the Pilot screen must be red. 2.5.6.3 Simulating a Gigabit Ethernet Alarm Two alarms can be easily obtained: Take the SFP module out of its housing: an "SFP Presence" alarm is triggered; the equipment " GbE Lnk/Act" LED goes out, the "GE" LED of the Pilot screen and the "SFP Presence" LED in the alarm detail becomes red. Put back the SFP module without the link cable: an "SFP LOS" alarm is triggered; the equipment "GbE Lnk/Act" LED stays lit green, the "GE" LED of the Pilot screen and the "SFP LOS" LED in the alarm detail becomes red. 2.5.6.4 Simulating a tributary alarm A tributary alarm is easily obtained by changing the configuration from normal (N) to invert (I), or vice versa. The equipment "trib" LED and its image on the Pilot screen must be red. When the test is finished, do not forget to restore the initial configuration. 2.5.6.5 Simulating an RSL alarm First check that the ATPC is OFF. An RSL alarm can be simulated by reducing the remote terminal power and choosing a suitable RSL alarm threshold, e.g. -60 dBm. Decrease the remote transmit power in order to have a receive level below -60 dBm. Take care not to drop below the link operating threshold, since the link cannot be restored from the local terminal. The equipment "RSL" LED and its image on the Pilot screen must be red. When the test is finished, do not forget to restore the initial settings. 2.5.6.6 Testing an external alarm To simulate a custom alarm, use the Pilot menu Configuration / Alarms / Local - IDU tab. Depending on the alarm convention, select " N" if a closed loop corresponds to the alarm state, or "I" if an open loop corresponds to the alarm state. In order to test a specific external alarm, first disable all other external alarms. Identify the pin of the 15-pin DB connector corresponding to the alarm input. Assuming that the alarm is in "N" configuration, connect this pin to ground and observe the changes on the front panel of the IDU and on the Pilot screens. The "ext" LED on the IDU front panel and its image on the Pilot screen must be red. Check that the alarm disappears when the pin is disconnected from the ground. 2.5.6.7 Testing the alarm outputs (relays) A multimeter is required for this test, to check continuity between the relay contacts. The 3 contacts of each relay are available on the 15-pin DB connector (see Figure 1.11 and Figure 1.12) When the IDU is not powered, NC is connected to the common point of the relay.


When the IDU is powered and when there is no alarm: NO is connected to common • NC is in open circuit • When the IDU is powered up and there is an alarm on the relay under test NC is connected to Common • NO is in open circuit • Simulate various alarms and test the operation of the relays as explained above.

2.5.7 - Testing 1+1 configuration (optional) 1+1 systems require additional tests compared with unprotected systems. These tests are carried out to check that all parts are operational and that the switching system operates correctly. These tests must be carried out on both ends of the link and require the presence of personnel in each station. In hot standby mode, only one transmitter is active, the other is muted. In frequency diversity mode, the two transmitters operate permanently, transmitting at two different frequencies, and only the receivers are switched. In 1+1 hot standby configuration, since asymmetric couplers are used (6 dB), the default system configuration is revertive automatic switching. In this mode, the transmitter and receiver of the main channel are given priority, operation being switched over to the standby transmitter or receiver in case of fault. When the fault disappears, the system switches back to the main transmitter or receiver. In the figures below, the active transmitter and receiver are written in bold. When the link is in operation and there are no faults, the configuration is as follows: (note: L = local, R= remote).

From the local terminal, connect a BER analyzer on one of the 2 Mbit/s channels and make a remote loopback for this channel (see procedure in section 3.4 -). If there is no E1 installed, make a Gigabit Ethernet test as specified in section 2.5.3). Check that there are no errors (or no frame loss) for at least a minute (nominal RSL conditions, ATPC OFF). From the local terminal, in "Super User" mode, select menu "Maintenance/Tx/Rx Forcing" to access the manual switching command (refer to § 4.21 -). Select the standby receiver by clicking on the Rx2 box, and validate.

Clear the counter and check that in this configuration, there is are no transmission errors. If revertive automatic switching is on, select automatic switching during transmission and reception by clicking on the "Tx Auto" and "Rx Auto" boxes. The system should return to the main ODU (transmitter and receiver). Errors are generated in case of a transmitter switch. If revertive automatic switching is off, switch on to the main channel manually then click on the " Tx Auto" and "Rx Auto" boxes. The system is now in automatic mode, the orange maintenance LED is off. Use the same procedure from the remote terminal.

2.5.8 - Quality measurement The link quality can either be measured on a Gigabit Ethernet access or on one or more chained E1 accesses (if the option is installed). Since the bit error rates on the Gigabit Ethernet train and on the E1s are the same, it is simpler to carry out this test on an E1 tributary of the option is installed. The test is either carried out with the arrangement as described in paragraph 2.5.3 - or that described in paragraph 2.5.4 -.


For a 1+1 link, only the quality on the main ODUs in automatic switching mode will be tested. The duration of the BER test depends on the type of network and the criticality of the links: Generally: • •

30 minutes for low capacity links (GSM, Wifi, etc.) 24 hours for medium and high capacity links.

Other durations could be considered upon request, but this will require Sagem approval.

2.5.9 - Recording configuration information The configuration information can be recorded by the Pilot into files. These files must be attached to the commissioning form Link configuration information Open the "File/System Report" menu, the following screen is displayed:


Check all the boxes and click on "Save As". Save the file in the PC using a name indicating the local site and the remote site: "[local site name] – [remote site name].txt". This text file contains information used to configure the local and remote sites, as well as information regarding the hardware and software versions (serial numbers, manufacturing date, versions, etc.). To print the file, click on "Print".

Saving local and remote terminal configurations The configurations can be saved in files on the PC. If the IDU or the ODU is replaced, these files can be used to reload the configuration quickly. To configurations are saved via the menu: "File/IDU Configuration/Local or Remote/Save". Chose a file name indicating the names of the sites on the two ends of the link, e.g.: "[local site name] – [remote site name].sav", for the local terminal "[remote site name] – [local site name].sav", for the remote terminal. Configurations are loaded via the menu: File/IDU Configuration/Local or Remote/Load.

3. FINAL LINK CONFIGURATION

Once the link is established, the configuration must be finalized via the Pilot, still in "Super User" mode. The following parameters must still be entered: •

Useful information stored in the IDU memory, e.g. site names and some information which it could be useful to consult or load later.

•

Gigabit Ethernet access configuration

•

2 Mbit/s access configuration

•

BER and RSL alarm thresholds

•

Configuration of local or external alarms, their severity, relays

•

Commissioning if necessary and configuration of Automatic Transmit Power Control (ATPC)

•

Interleaver configuration

•

1+1 Switching configuration

3.1 - ENTERING SITE NAMES Enter the site names of the two terminals in "Site Name" (e.g. the equipment IP addresses).


3.2 - SETTING THE PILOT DATE AND TIME Click at the bottom left of the Pilot main screen to display the following screen:

The date of local and remote equipment can be modified. Click on "Synchronize" then "Apply" to transfer PC date and time to the equipments, independently for the local and remote terminals or for both at the same time.

3.3 - CONFIGURING THE GIGABIT ETHERNET ACCESSES SAGEM-LINK F-H can be used to transmit Ethernet frames simultaneously or not with 2 Mbit/s tributaries. The principle for transmission of these frames and the specific functions that can be associated with them are described in § 7-GIGABIT ETHERNET FUNCTION.

3.3.1 - "Configuration / Gigabit Ethernet / Ethernet port configuration / Local or Remote" menu Open this menu or click on one of the connectors in Shelf view.


Topology network mode: - P2P: allows point to point connection between the GE1 ports of the local and remote equipment. This configuration must be carried out on local and remote equipment. - Y shape: used to transmit traffic on several GE ports of an IDU to the remote terminal. This configuration must be carried out on local and remote equipment. Jumbo frame mode: check "Enable" if Ethernet frames are longer than 1760 bytes. Jumbo frame mode is guaranteed for frames of up to 10 000 bytes in P2P and 8192 bytes in Y shape. Jumbo frames are not available with QoS features. Port Id: select the port to be configured Port mode: check "Enable" or "Disable" Interface: Select optical (SX Fiber or LX Fiber) or electrical (Copper) interface Auto negotiation / Speed / Duplex: for an electrical interface ("Copper" box checked) the transmission speed can be managed automatically (Auto negotiation checked "Enable") or configured manually (Auto negotiation checked "Disable"): 10 Mbps Half Duplex (transmission and reception frames processed separately) or Full Duplex (transmission and reception frames processed simultaneously), 100 Mbps Half or Full Duplex, 1000 Mbps.

3.3.2 - "Configuration / Gigabit Ethernet / Radio channel configuration / Local or Remote" menu

Radio bandwidth: indicates the radio bandwidth available for the designated channel Traffic shaping mode: check "Enable" to manage QoS and limit the port throughput for radio transmission. Note that when this function is enabled, the maximum throughput available is reduced slightly (about 6 % compared with a configuration without shaping, if shaping bandwidth = 100 %). Traffic shaping bandwidth: if Traffic Shaping Mode is on ("Enable" box checked), a percentage of the radio bandwidth available can be allocated. If this parameter is set to 100 %, there is no limitation.


3.3.3 - "Configuration / Gigabit Ethernet / Advanced configuration / QoS configuration / Local or Remote" menu Note: this menu can only be accessed if Traffic Shaping is enabled (see § 3.3.2 -) and if Jumbo frame is disabled (see § 3.3.1 -) Priority mode: used to define the priority of within S-Vlan(s) - Port priority: all frames entering a GE port have the priority defined in the "Priority" field of the selected port (Low, Normal, High or Very high).

- User priority: the priority assigned to the frames entering the GE port is based on the priority field contained in these frames (User priority). A configurable table gives the mapping between the User priority (UP) field and the priority used within the S-Vlan (service priority) For frames which do not contain this information, the priority defined by default in the "Default QoS" field (Low, Normal, High or Very high) is assigned.

Very high queue priority radio bandwidth : this parameter is used to define the throughput reserved for frames with "Very high" priority.


3.3.4 - "Configuration / Gigabit Ethernet / Advanced configuration / Congestion configuration / Local or Remote" menu

Flow control mode: this function is used to prevent frame congestion during the radio transmission whose bandwidth is limited with respect to t he throughput at the Gigabit Ethernet access. Client equipment connected to the GE ports must be configured to manage the pause frames (see § 7). Metering mode: used to defined a guaranteed throughput per port; metering is guaranteed if the operator configures its quality of service as "Port priority" and if each port has the same priority (if all flows have the same priority; it is strongly recommended to use priorities "Very high" and "High"). Port Id: selects the port on which the CIR will be configured CIR: configures the throughput guaranteed on each GE port, as a percentage of the radio bandwidth

3.3.5 - "Configuration / Gigabit Ethernet / Advanced configuration / Security configuration / Mac filtering / Local or Remote" menu

Frames with a particular MAC address can be prohibited from transiting in the S-Vlan. 16 MAC addresses can be prohibited; for each address, specific whether it is a source address (SA) or a destination address (DA).


3.4 - CONFIGURING 2 MBIT /S ACCESSES Click on one of the "TRIB" connectors in the Shelf view or open the "Configuration / E1 Tributaries / Local or Remote" menu to open the window used to configure the 2 Mbit/s accesses. This screen may vary depending on the current capacity. A screen example for a capacity of 16 x 2 Mbit/s accesses is given below:

When this button is "ON", an AIS signal is transmitted when BER > BER Threshold Alarm

I: the access is not used N: The access is used (Normal)

Blank: active (normal) S: AIS transmission

BAL 75: The connector corresponding to this group of tributaries is i balanced 75 Ohm configuration

Blank: No loopback L: Local loopback R: Remote loopback

Click on the corresponding button to change the settings. •

AIS insert on BER: when this button is ON, an AIS is transmitted when the BER is greater than -3 10 .

•

Monitoring: •

If the access is not connected, configure it as invert "I". In this case, no alarm is generated since there is no signal at the input. However, if the access is configured as invert, a tributary alarm is generated if a signal is present.

•

If the access is used for traffic, it must be configured as normal "N". In this mode, an alarm is generated if there are no signals on the access.

•

Service: In normal operation, select "blank" button (active). If "S" is selected, an AIS is returned locally on the reception access of the channel concerned. Note that, in this case, no AISs are transmitted to the remote terminal.

•

Loopback: click on a button on the loopback line to display the screen providing access to the various loopbacks: The screen can also be displayed from the " Maintenance / Loopbacks" menu


Check one or more boxes to activate remote loopback

Check one or more boxes to activate local loopback

Set the loopback time required

Click here to apply

Click here to activate a multiplexer loopback

From this screen it is possible to activate a local or a remote tributary loopback, or a local multiplexer loopback. A loopback time can be defined for the link so that it returns to non-looped back mode automatically. When a remote loopback is activated, a maintenance indication is displayed in the Pilot status bar, the orange "Maint" LED on the IDU front panel and its image on the Pilot are lit. 2 Mbit/s remote tributary loopback The principle of remote loopback is explained in the following diagram:

Local loopback is used to check the wiring on the local terminal. Remote loopback is used to check the radio transmission. Multiplexer loopback (IDU Card) Multiplexer remote loopbacks operate in the same way as tributary remote loopbacks, except that they are carried out on the resulting train. Remote loopback is used to test multiplexer operation.


•

Interface: Each 44-pin sub-D connector on the front panel includes the access for eight 2 Mbit/s inputs/outputs. The electrical interface of the accesses can be configured by the Pilot one connector at a time by clicking on the corresponding Balanced 120 / Unbalanced 75 buttons.

3.5 - CONFIGURING THE ALARM THRESHOLDS BER and RSL alarms thresholds can be adjusted with the Pilot software. Open the "Configuration / Alarms / Local" menu or click on the "Alarms In/Out" connector in the Shelf view.

3.5.1 - BER alarm thresholds Select the Modem tab. -3

-6

Two BER thresholds can be configured: BER Alarm (default: 10 ) and BER Warning (default: 10 ) These thresholds may be modified between 10

-3

-6

and 10 . It is advised to keep the default values.

3.5.2 - RSL alarm threshold Select the Radio tab. The threshold can be adjusted between -40 dBm and -70 dBm (default: -60 dBm).


3.6 - CONFIGURING THE ALARMS Configuration is carried out via the "Configuration / Alarms / Local or Remote" menu, by clicking on one of the "Relay" LEDs on the Pilot front panel, or by clicking on the "Alarms In/Out" connector on the Shelf view. Six tabs are available to configure the site alarms, their severity, their assignment to a relay and their transmission to the manager. Whenever a box is checked, an "Apply" window is displayed: click to validate the configuration. A view of each of the six tabs is given for information or to indicate a special configuration. The meaning of the alarms is described in § 5.5.1 -.

3.6.1 - General parameters On all tabs, each alarm can: •

be assigned to one or more relays if the corresponding boxes are checked; the default assignment of the relays is given in § 3.6.8 -

3 relay outputs are available on the " Alarms IN /OUT" connector. These relays are fully programmable: Internal local alarms or external (local or remote) alarms can be assigned to each relay. Relay operation can be enabled or disabled by checking or unchecking the "Enable relays" box in "General Parameters"; in the default configuration, the box is checked. If an alarm is generated the names of the alarm and of t he associated relay are written in r ed. Click on a Relay box to check or uncheck all boxes in the alarm column in one go. •

Define a severity level: "None", "Warning", "Minor", "Major" or "Critical" by checking the corresponding box. The default alarm severities are indicated in the tables of § 5.5.1 -

•

Check the corresponding box "Enable Trap", if you want to send the SNMP trap to network managers. The default configuration is "box checked" for all alarms except for "Link Status" and "Rx Frame".

The traps sent to the network manager can be filtered according to the severity: check the "Disable traps with severity" box corresponding to the severity level you do not want to send the trap to the manager, for all alarms configured at this level; the default configuration is "box unchecked". The list of managers authorized to manage the equipment traps can be completed by clicking on "Trap Managers". The maximum number of authorized managers in a network is 10.

Add, modify or delete a manager

Enter the IP address of the authorized manager to be added


3.6.2 - "IDU" tab

SAGEM-LINK F-H can manage up to 5 external alarm inputs available locally. These signals are connected to the "Alarms IN /OUT" connector. The pinout of this connector is given in § 1.7.2.3. These five alarms can only be configured locally and named; they will be either: •

"D": the alarm is disabled

•

"N": the alarm is configured as normal; there will be no alarms if the corresponding input on the connector is in open circuit, and an alarm will be generated if this input is shorted to the ground.

•

"I": the alarm is configured as invert; the alarm state corresponds to open circuit.

SAGEM-LINK F-H can also display locally the 5 alarm inputs from the remote terminal by checking the corresponding box; the "ext" LED of the local IDU will be red. If the status of any activated external alarm changes, the "Ext" LED on the IDU front panel is lit red. This tab can also be used to display or not an alarm regarding the Wayside channel by checking or unchecking the corresponding box.


3.6.3 - "Modem" tab

This tab can also be used to set the BER alarm thresholds (see § 3.5.1 -).

3.6.4 - "Radio" tab

This tab can also be used to set the RSL alarm thresholds (see § 3.5.2 -).

3.7 - CONFIGURING THE AUTOMATIC TRANSMIT POWER CONTROL (ATPC) ATPC is used to increase the density of a network by allowing frequency reuse. This process consists in automatically reducing the transmit power of each transmitter, while keeping good transmission. ATPC must not be active during antenna installation and commissioning. ATPC settings depend on the structure of the network (frequency re-use, radio interferers, link margin). The operator must define 3 main parameters: •

Maximum ATPC transmit power

•

Minimum ATPC transmit power

•

ATPC reception threshold

The minimum and maximum powers must be within the transmitter power ranges, and the difference between maximum and minimum power must not exceed 20 dB. The ATPC reception threshold must be within the range -50 dBm to -80 dBm.


The ATPC process consists in reducing transmit power as low as possible within the specified range while ensuring that there are no transmission errors and that the received level on the remote terminal remains greater than or equal to the specified threshold. To enable ATPC, click on the ATPC button and set it to "ON". ATPC parameters are configured via the Configuration / ATPC / Local or Remote / Channel 1 or Channel 2 menu.

Enter the three values and validate with the Apply button.

Note: Use of ATPC with 1+1 Hot Standby Systems When ATPC is used in a 1+1 system with coupler, the ATPC parameters are defined at antenna access. The power values entered in the above dialog box must take into account the coupler loss. These values are defined only for the main ODU. Example: If the ODU can deliver +25 dBm and the loss of a 6 dB coupler on the main path is 2 dBm, the maximum power at antenna access will be +23 dBm for the main ODU.

3.8 - CONFIGURING THE INTERLEAVER In the default configuration, interleaver is disabled (OFF) in order to minimize data transfer time (latency). However, when the network does not require a low latency, error correction is improved with the interleaver ons. To configure the interleaver, double click on the parameter bar at the top of the screen to open the following window.


Click on the ON/OFF button to change the interleaver configuration and validate. The interleaver configuration must be the same on both terminals of the link. So, it is necessary to configure first the remote terminal, then the local terminal.

3.9 - SPECIFIC CONFIGURATIONS FOR 1+1 SYSTEMS Revertive Automatic Switching This option gives priority to the transmitter and receiver of the main channel in 1+1 operation. When this box is checked "ON", the transmitter and the receiver in traffic are those from the main ODU. If there is a fault on the main channel, traffic is switched over onto the standby channel. When the fault on the main channel disappears, the system switches the traffic back to the main channel. Click on the protection button of the Pilot screen or open the "Configuration / Protection / Local or Remote" menu to display the following screen:

When the revertive automatic switching option is not selected, transmit switch and receive switch positions are free. The system stays in the current position until a fault appears. Note that the transmit and receive switches are independent.


4. OPERATION – PILOT SAGEM-LINK F-H operation and maintenance are carried out: -

directly on the equipment, via the LEDs on the front panel

-

When the equipment is off, the log is kept in the flash memory.

4.5 - CONFIGURATION / ALARMS MENU This menu is described in § 3.6 -.

4.6 - CONFIGURATION / MANAGEMENT NETWORK / ETHERNET PORTS AND RADIO CHANNEL / LOCAL OR REMOTE MENU 4.6.1 - Description of the Management network SAGEM-LINK F-H equipment can be operated via an SNMP type management network, via the Pilot software, and an SNMP manager (IONOS NMS). The equipment can be managed via the integrated network management interface acting as an IP router:

MGMT1 Ethernet

MGMT2

Switch L2

Network management interface

TSL/PPP (to remote IDU)

The router has two ports: - The IDU management Ethernet port (MGMT1 or MGMT2), associated with a MAC address. This MAC address is unique and non modifiable. An IP address is associated with this MAC address. - The radio port (TSL) communicating with the remote IDU via a PPP type protocol. To make the management system easier to implement, the IP addresses of these ports are managed internally and are transparent for the user.


To make the terminals easier to identify, a virtual IP address is defined for each terminal (terminal = IDU+ODU). This address will be used by the Pilot software and the network manager to identify the terminal. This address is independent of the IDU Ethernet port address and must not belong to the same subnet. This address is called the Management IP Address. The IDU Ethernet port IP address does not operate with SNMP, since the equipment always answers with the management address. A SAGEM-LINK F-H equipment can be connected via the IDU Ethernet interface to another equipment, whether or not SAGEM-LINK F-H. To route the datagrams on the various network elements, the routes to r each these elements must be defined. A route is defined for an IP network; e.g. 135.11 if the network mask is 255.255.0.0. The network entities can exchange their routes using the RIP and OSPF protocols. On IDU PPP interfaces, the OSPF protocol is systematically implemented. On IDU Ethernet interfaces, the user have to define whether or not to involve RIP or OSPF protocols. Static routes and a default gateway can be also be defined for each IDU.

4.6.2 - Network configuration

The meaning of the configuration parameters is described in the previous paragraph. On system initialization, the addresses are entered via the serial interface (VT100). These values can then be modified via the Pilot or the manager, but in this case, note that if an incorrect value is entered via a remote terminal, it will be impossible to reach the equipment and intervention on site will be required to put back the correct address. Port Id: used to display the statuses of the MGMT1, MGMT2 and Wayside ports

4.6.3 - Wayside configuration The Wayside is a point to point 10/100BaseT Ethernet channel between the local and remote equipment. This access can be physically disconnected by setting the "Wayside transmission" setting to "Off".


4.7 - CONFIGURATION / MANAGEMENT NETWORK /ROUTES / LOCAL OR REMOTE MENU This table lists the IP routes known by the equipment. Direct routes are known due to the configuration of the equipment interfaces. Indirect routes may result from the routing protocol (OSPF or RIP) or definition of a static route.

To add a static route, click on "Add"

The IP network to be reached is defined by the "Destination Address" and "Subnet Mask" fields For example: 10.142.0.0 / 255.255.0.0 The "Gateway" field is the equipment address to which network frames will be sent. If the Ethernet interface is to be used, the Gateway address must be in the Ethernet interface network; the MAC address of the Gateway will be used to reach it. If the TSL (PPP) interface is to be used, the Gateway address must be the remote equipment management address. Cost: defines the cost of using the route. There is a maximum of 20 static routes.


4.8 - CONFIGURATION / GIGABIT ETHERNET MENU This menu is described in § 3.3 -.

4.9 - CONFIGURATION / PROTECTION / LOCAL OR REMOTE MENU SAGEM-LINK F-H IDU is common to the 1+0 and 1+1 configurations. The hardware difference is that the 1+0 IDU uses only one modem while the 1+1 IDU contains two. There are two ways to establish a 1+1 link: - On first installation: with the two modems inserted in the IDU each modem being connected its ODU a cable. Switch on both modems to power up the terminal. - On a 1+0 link already established: there is no need to disconnect the link; install Modem2/ODU2 and switch on the second Modem. Then, to switch from one configuration to the other, use the Pilot software as described below. •

Click on the protection button of the Pilot screen or open the " Configuration / Protection / Local or Remote" menu to display the following screen:

•

Select the box corresponding to the new configuration and validate.

•

If the changeover is refused, there may be a hardware problem or the two ODUs may not be compatible with the required 1+1 mode (e.g. different ODUs in 1+1 HSB, etc.)

Perform these operations on the local and remote equipment. Note: It is important to have both terminals in the same configuration. Avoid having the two terminals in different configurations. The various system configurations are described in § 1.5 -

Revertive automatic switching: see § 3.9 -


RSL switching threshold: The RSL switching criterion is only active for space or frequency diversity configurations. In 1+1 hot standby configurations, this criterion is not taken into account. Enter the RSL switching threshold If the receive level of both receivers is greater than this threshold, the RSL switching criterion is not taken into account by the switching system. If the RSL of one receiver is below this threshold and if the two other criteria (alarm and BER) are the same on both channels, then the system selects the receiver with the best receive level. If the levels of both receivers are below the threshold and if the other criteria (alarm and BER) are the same on both channels, then the system permanently selects the receiver with the best receive level.

5.3 - TROUBLESHOOTING PROCEDURE The goal is to make a precise diagnostic of the problem, in order to determine the faulty unit quickly and replace it.

5.3.1 - Describe the symptom This is generally made by the field technician: common symptoms are "the link is broken", "there are excessive transmission errors", "there are alarms", etc. These symptoms may be permanent (failure) or intermittent. The alarm and event data and the graphic records available in the Pilot can generally be used to improve the diagnostic (§ 4.4 -).

5.3.2 - Isolate the problem Once the symptom has been defined, the faulty unit can be isolated using information supplied by the LEDs on the IDU front panel and the information available on the Pilot. SAGEM-LINK F-H replacement units are the ODU, the IDU (without modem and without FAN), the modem and the FAN drawer. A 1+0 link is composed of several units. The goal of this step is to determine what the most probable unit to replace is. The difficulty is that, in some cases, the problem may be generated by the remote terminal, external equipments (power supplies, bad interface signal levels, etc.) or the external environment (path obstruction, radio interferers, severe climatic conditions, etc.).

5.3.3 - Fix the problem Once the problem has been isolated, it is important to understand its cause and to apply corrective actions to avoid reoccurrence of the problem. Some typical problems are described in § 5.6 -.

Orange LED lit: collision

The "FAN" LED is red if the FAN module or one of the fans is faulty.

5.4.2 - Description of the Modem front panel LEDs •

The " MODEM" LED is red if there is a problem on the ODU cable, if the modulator, demodulator or power supply is faulty, or if the link is down (no received data).

•

The "RSL" LED is red if the level received by the ODU is below the programmed threshold, or if there is a BER alarm (BER alarm, or BER warning). In most cases, this alarm corresponds to a propagation or radio interferer problem.

•

The "ODU" LED is red if there is an ODU alarm or if an ODU is not connected (cable problem). The LED is also red if the ODU is muted on a 1+0 link or if the two ODU of a 1+1 link are muted.

•

The "POWER" LED is green when the modem is powered up.

5.5.2 - Direct and indirect alarms There are two types of alarm in a microwave radio link: •

Direct alarms which occur when there is a fault on a unit (e.g. transmit frequency alarm)

•

Indirect alarms caused by a fault on another unit or by an external problem To determine the cause of an indirect alarm, analyze all possible causes of the alarm and select the most likely

5.5.3 - Event log In some cases with transient faults, it may be worthwhile examining the graphic log available and the alarm or event data to determine the cause of the fault (§ 4.4 -)

5.6 - T YPICAL SAGEM-LINK F-H PILOT SCREENS IN CASE OF PROBLEM The following screens are representative of some typical problems.

5.6.1 - No IDU-Pilot software communication When connecting the IDU to the PC, the following screen may be displayed:

The Pilot cannot communicate with the IDU. Check the Ethernet cable between IDU and PC and check that the IP addresses and subnet masks of the PC and the IDU are compatible. From the PC, ping the IDU Ethernet address. If the ping result is negative, change the IP address of the PC or of the IDU Ethernet port (see § 2.2 -). -).

5.6.2 - No local equipment, no remote equipment If the connection between PC and IDU breaks during a Pilot session, the Pilot displays the following screen:

Check that that the IDU is powered correctly and that the Ethernet cable between the PC and the IDU is correctly installed.


5.6.3 - No local radio The IDU is recognized by the Pilot, but the ODU does not operate: absent, faulty or not answering the IDU requests. In this case, the typical Pilot screen is as follows:

Check the cable between IDU and ODU. I f the problem remains, replace the ODU or the modem.

5.6.4 - No remote radio The local terminal operates correctly but communication with the remote terminal is down. In this case, the typical Pilot screen is as follows:

Check the remote terminal configuration (frequency, capacity, modulation, transmit power), correct antenna alignment and possible presence of obstacles between the two antennas. In the bottom bar, the software suggests trying to "unmute" the remote equipment, which could be one of the reasons why it fails to operate. Go to the maintenance menu to access this command.

SAGEM-LINK F-H Installation and Operation Manual – 253 129 101-01 Page 104/134 Sagem Communications Communications document. Reproduction and disclosure prohibited

5.6.5 - Low RSL The link is established but the RSL is low. The typical Pilot screen is as follows:

Check antenna alignment, transmit power levels and make sure that the fault is not due to a temporary propagation problem.

5.6.6 - Low transmit power The RSL of one of the two terminals is too low with respect to the other terminal. In this case, the typical Pilot screen is as follows:

Increase the transmit power if possible. If the problem remains, replace the ODU on the site with the doubtful transmitter.


5.6.7 - Link established correctly but with some alarms

Check the alarm configuration (§ 3.6 -).

5.6.8 - Normal link no alarms The link is established without alarms. All LEDs are green.

Figure 6.6 - 1+1 hot standby configuration

The 1+1 HSB configuration involves the following principles: •

The main and standby ODU operate at the same frequency and are connected to a single antenna with a coupler (6 dB or 3 dB coupling),

•

When one transmitter is in traffic, the other is in mute position,

•

Both receivers are operational,

•

Transmitter and receiver switch controls are independent.

•

The transmitter and receiver switches are controlled by the local terminal information. In normal operation, the remote terminal does not control the local terminal switch.

•

Manual switching (forcing) is available via the Pilot software

•

The receiver switch has a hitless feature: error-free switching under some conditions.

In frequency diversity mode, there is no switching at the transmit side. The two transmitters transmit permanently at two different frequencies. Switching is carried out only on the receive data.


7. GIGABIT ETHERNET FUNCTION

7.1 - S_VLAN SERVICES SAGEM-LINK F-H is used to transmit an receive Gigabit Ethernet frames to / from remote equipment. A GE Switch is implemented in the IDU in order to carry one or more VLAN transport services (S_VLAN). Each S_VLAN service routes Ethernet frames via an Ethernet bridge. Frames leaving the radio port are tagged with an S_VLAN tag according to IEE 802.1ad specification. The Switch is transparent to C_VLAN IDs. It only processes the "User Priority" field.

7.2 - PORTS 7.2.1 - Definition The "radio port" corresponds to radio transmission between the two terminals. Since the radio transmission bandwidth is limited, this is the main point of congestion for the Ethernet transmission. The available bandwidth depends on the radio configuration (modulation, radio channel bandwidth) and the number of optional E1 channels activated. GE ports are the Gigabit Ethernet transmission accesses; they can associated with either optical interfaces (SX or LX), or electrical interfaces (10/100/1000BaseT). Electrical SFP ports can handle throughputs of 10/100/1000 Mbit/s in Full or Half duplex, except for 1000 Mbit/s which must be in Full duplex. The throughput and mode can be negotiated automatically (Auto negotiation "enable") with the remote Ethernet port.

7.2.2 - Radio port shaping The throughput of S_VLAN data leaving the radio port can be limited by a mechanism called "Port Shaping" which ensures that the throughout does not exceed the port physical capacity. By default, Port Shaping is set to 100 % of the physical capacity but can be reduced for specific requirements.

7.2.3 - Jumbo frames If the Ethernet frames received on the GE ports are larger than 1760 bytes, jumbo frame mode must be configured.


7.3 - TOPOLOGY Communication between ports is limited to two topologies: - "Peer to Peer" (P2P), where the Gigabit Ethernet ports #1 of each terminal are connected via a S_VLAN bridge (Virtual LAN bridge). The Gigabit Ethernet #2 port is disabled. - "Y Shape", where the two GE ports are activated, and connected to the remote terminal by the radio using S_VLAN bridges. Data from a GE port cannot be routed locally on another GE port (implementation of PVE: Private VLAN Edge).

7.4 - CONGESTION If the data rate from the GE ports via the radio port is greater than the rate defined by the radio Port Shaping, congestion will occur at the output resulting in data loss.

7.4.1 - Eliminating congestion To eliminate congestion, the data rate from the GE ports can be limited by implementing a flow control mechanism. If the radio port reaches the congestion limit, the switch sends a command (pause) to the GE ports to stop data transmission; when congestion has been cleared, the switch sends a command to the GE ports to resume data transmission; the GE ports must be configured to process the pause commands.

7.4.2 - Processing congestion 7.4.2.1 Description Two additional mechanisms are implemented to process the congestion. - Processing of alarms entering the S_VLAN service which controls the traffic according to the rate - Processing of the output frames via queues. 7.4.2.2 Traffic control To control the traffic, a contractual data rate must be defined for each flow from a GE port entering an S_VLAN service. Note: for release R1.2, the contractual rate is defined by port, not by flow. This contractual rate (CIR: Committed Information Rate) defines the rate below which all incoming frames are guaranteed to be routed on the radio port. A metering system determines the instantaneous rate of the incoming flows. When the instantaneous rate is greater than the CIR, all frames in this flow are said to be "out of profile" and are coloured red internally. When the instantaneous flow is less than or equal to the CIR, all frames of this flow are coloured green internally. In case of congestion at output, the red frames can be deleted. This mechanism allows occasional bursts. 7.4.2.3 Output queues A queue mechanism is used to sort the frames according to priority criteria, absorb the temporary bursts and delete the red frames in case of saturation.


7.5 - QUALITY OF SERVICE (QOS) Routing of frames from one port to another takes a certain amount of time on the transport network (S_VLAN), called latency. Depending on the data routed, this time may have to be reduced (e.g. telephone data). To perform quality of service (QoS), each frame is tagged when entering a S_VLAN service. By configuration, this priority is either allocated by default to all frames from a GE port and entering an S_VLAN service, or based on the priority which was already allocated by the equipment of the uplink customer network (User Priority - UP, contained in the Ethernet frame (802.1d)); the Switch allocates a default service priority to any f rame which does not contain a UP field. QoS is managed using a mechanism involving 4 output queues (Traffic Class - TC). - TC 0: "very low" priority; - TC 1: "low" priority; - TC 2: "high" priority; - TC 3: "very high" priority; Queues TC0, TC1, and TC2 are WRR (Weighted Round Robin) type; these queues are emptied in turn, queues with the highest priorities first; a maximum of n frames are extracted from a TC before moving to the next one; n is known as the weight. The weights are respectively 16, 8 and 4 for TCs 2, 1 and 0. Queue TC3 is SP (Strict Priority) type; it is emptied continuously in proportion to the bandwidth allocated (very high queue priority radio bandwidth). The frames are distributed in the various queues depending on the service priority allocated to them in input. If the priority is configured globally for the entire data flow from a port and entering an S_VLAN service (Port Priority), the Switch distributes all the frames of this flow to the TC configured (Priority). If the priority used is that of the fr ames received (User Priority), the allocation rule is as follows: UP 0 and 3 => TC0, UP 1 and 2 => TC1, UP 4 and 5 => TC2, UP 6 and 7 => TC3, Frames with no UP field will be directed to the TC configured (Default QoS). The Switch eliminates frames according to their source or destination MAC address (black list, maximum 16 addresses). The Switch can read the statistics counters for the data passing through the port; they are classified as transmission/reception and with/without errors and can be reset for all ports at the same time. The Switch can also read the metering statistics counters; the counters record the number of bytes in green frames (rate less than or equal to the CIR) and the number of bytes in red frames (rate greater than the CIR).

Note 1: the minimum and maximum frequencies in these tables correspond to the ODU diplexer bandwidth transmission side, not channel frequencies. The channel frequencies available depend on the selected channel occupied bandwidth. The frequency of the first channel is equal to the minimum diplexer frequency + half the band corresponding to the transmitted spectrum. The frequency of the last channel is equal to the maximum diplexer frequency - half the band corresponding to the transmitted spectrum. The band corresponding to the transmitted spectrum is 40 MHz for a 56 MHz Tx/Tx spacing, 20 MHz for a 28 MHz Tx/Tx spacing (see also § 6.2.5 -).
