2 FIRST AID FOR ELECTRICAL SHOCK AND SAFETY RULES

2.1 FIRST AID FOR ELECTRICAL SHOCK

Do not touch the patient with bare hands until the circuit has been opened. Open the circuit by switch-ing off the line switches. If that is not possible protect yourself with dry material and free the patientfrom the conductor.

2.1.1 Artificial respiration

It is important to start mouth resuscitation at once and to call a doctor immediately. Suggested procedurefor mouth to mouth resuscitation method is described in the Tab.1.

2.1.2 Treatment of burns

This treatment should be used after the patient has regained consciousness. It can also be employed whileartificial respiration is being applied (in this case there should be at least two persons present).

Warning

• Do not attempt to remove clothing from burnt sections

• Apply dry gauze on the burns

• Do not apply ointments or other oily substances.

AL - MN.00142.E - 009 9

Tab.1 - Procedure for mouth to mouth resuscitation method

Step Description Figure

1

Lay the patient on his back with his arms parallel to the body. If the patient is laying on an inclined plane, make

sure that his stomach is slightly lower than his chest. Open the patients mouth and check that there is no foreign mat-

ter in mouth (dentures, chewing gum, etc.).

2

Kneel beside the patient level with his head. Put an hand under the patient's head and one under his neck.

Lift the patient's head and let it recline backwards as far as possible.

3

Shift the hand from the patient's neck to his chin and his mouth, the index along his jawbone, and keep the other

fingers closed together. While performing these operations take a good supply of oxygen by taking deep breaths with

your mouth open.

4With your thumb between the patient's chin and mouth keep his lips together and blow into his nasal cavities.

5

While performing these operations observe if the patient's chest rises. If not it is possible that his nose is blocked: in that case open the patient's mouth as much as possible by pressing on his chin with your hand, place your lips around his mouth and blow into his oral cavity. Observe if the pa-tient's chest heaves. This second method can be used in-

stead of the first even when the patient's nose is not obstructed, provided his nose is kept closed by pressing the nostrils together using the hand you were holding his head with. The patient's head must be kept sloping back-

wards as much as possible.

6

Start with ten rapid expirations, hence continue at a rate of twelve/ fifteen expirations per minute. Go on like this until the patient has regained conscious-ness, or until a

doctor has ascertained his death.

5 SYSTEM PRESENTATION

5.1 RADIO SYSTEM OVERVIEW

5.1.1 General

AL is SIAE's PDH radio series for low-to-medium transmission capacities in frequency bands from 7 to 38GHz.

Different hardware versions offer a range of tributaries traffic from 2xE1 to 32xE1, with or without Ethernettraffic, on 4QAM, 16QAM and 32QAM modulation, with capacity up to 105 Mbit/s.

Reduced cost, high reliability, compact size, light weight and full programmability are the key features ofthis radio series.

5.2 COMPLIANCE WITH INTERNATIONAL STANDARDS

The equipment complies with the following international standards:

• EN 301 489-4 for EMC

• ITU-R recommendations for all frequency bands

• EN 300 132-2 characteristics for power supply

• EN 300 019 environmental characteristics (Operation class 3.2 for IDU and class 4.1 for ODU; stor-age: class 1.2; transport: class 2.3)

• EN 60950 for safety.

5.3 APPLICATIONS

AL main applications are:

• radio communication between GSM cells

• radio links for voice and data transmission

• spur routes for high capacity radio system

• emergency links

• Ethernet traffic in point to point communication.

16 AL - MN.00142.E - 009

5.4 SYSTEM ARCHITECTURE

The AL radio equipment consist of two separate units:

• the indoor unit (IDU) that houses tributary interfaces, Ethernet ports modem and controllerunits

• the outdoor unit (ODU) that converts IF signals into RF signals and vice versa.

The two units are interconnected via coaxial cable. Fig.5 and Fig.6 show a typical IDU/ODU layout whereasFig.7 and Fig.8 show the radio block diagram in 1+0 and 1+1 configuration respectively.

5.4.1 IDU

The IDU is available in the following hardware versions:

• ALC

- 1 rack unit compact IDU, 1+0 configuration, 2/4/8 E1

- 1 rack unit compact IDU, 1+0 configuration, 2/4/8/16 E1

- 1 rack unit compact IDU, 1+1 configuration, 2/4/8 E1

- 1 rack unit compact IDU, 1+1 configuration, 2/4/8/16 E1

• ALC plus

- 1 rack unit compact plus IDU, 1+0 configuration, 2/4/5/8/10/16 E1

- 1 rack unit compact plus IDU, 1+1 configuration, 2/4/5/8/10/16 E1

- 1 rack unit compact plus IDU, 1+0 configuration, 2/4/5/8/10/16/20/32 E1

- 1 rack unit compact plus IDU, 1+0 configuration, 2/4/5/8/10/16/20/32 E1

Ethernet module can be housed inside IDU, as option, for Ethernet traffic. ALC and ALC plus IDUs consistof a single circuit board plugged into a wired shelf. Line interfaces house tributary connections and, througha multiplexing/demultiplexing and bit insertion/extraction process, supply/receive the aggregate signalto/from the modulator/demodulator.

Main difference between ALC IDU and ALC plus IDU is the increased capacity (up to 32E1 and up to 105Mbit/s of total capacity) and the possibility to use the bandwidth of transmitted channel more efficiently:5 E1 streams can be transmitted in the bandwidth previously used by 4 E1 only, 10 E1 streams can betransmitted in the bandwidth previously used by 8 E1 only, 20 E1 streams can be transmitted in the band-width previously used by 16 E1 only.

Line interfaces carry out the digital processing for the QAM modulator and, in 1+1 configuration, duplicatethe main signals on the transmission side and perform the changeover on the receive side. Interfaces to-wards the ODU house the cable interface for bidirectional communication between ODU and IDU, and im-plement the IF section of the mo-demodulator.

IDU power supply units process battery voltage and supply power to IDU and ODU circuits. The controllersection of the radio houses service channels interfaces, stores IDU firmware, interfaces SIAE man-agement systems though dedicated supervision ports, and routes external and internal alarms to relaycontacts.

5.4.2 ODU

The ODU houses the interface towards the IDU on one side, and towards the antenna flange on the other.The ODU shifts the incoming QAM-modulated carrier to RF frequency through a double conversion. Theopposite occurs at the receive side, when the IF-converted carrier is sent to the IDU demodulator.Antenna coupling in 1+1 systems is done through a balanced or unbalanced hybrid.

Two versions of ODU are available, ODU AL and ODU AS; they differ in output power.

AL - MN.00142.E - 009 17

5.5 MANAGEMENT SYSTEMS

AL radio can be controlled locally and remotely via SIAE supervision software:

• SCT/LCT: a Windows-based management system for small networks (up to 100 NE)

• NMS5-LX: a Linux-based management system for small-to-medium networks (up to 750 NE)

• NMS5-UX: a Unix-based management system for large networks (up to 2500 NE)

These systems provide a friendly graphic interface complying with current standard use of keyboards,mouse and windows.

5.5.1 Management ports

AL radio terminals connect to the supervision network via the following communication ports:

• Ethernet 10BaseT Port (2 port in ALC plus)

• USB port

5.5.2 Protocols

SNMP along with IP or OSI protocol stacks are used to manage AL operation.

8 DESCRIPTION OF THE INDOOR UNIT – PDH IN-TERFACES

8.1 1+0/1+1 IDU

The following functional description covers the versions the IDU consists of as shown in chapter "Equip-ment technical specifications".

The IDU is made up of a single motherboard that houses all the circuitry realizing the following function-alities:

• Line interface

• Radio interface

• Equipment controller

• IDU loops.

The different versions of IDU are pointed out in following description only if it is necessary.

8.1.1 Line interface

The line interface performs the following operations:

• multiplexing process of the input tributaries

• generation of the aggregate frame by aggregating multiplexed tributaries and service channel.

Bit extraction and demultiplexing process happens at the receive side.

Tx side

Refer to Fig.19. The 2 Mbit/s input signal is code converted from HDB3 to NRZ format before being multi-plexed. The multiplexing scheme depends on the number and the bit rate of the input tributaries. Attachedfigures show different multiplexing scheme as follows:

• Fig.20 – 2x2 Mbit/s multiplexing. The mux performs stuffing operation on each single tributary andgenerates a proprietary frame embedding the two tributaries to be sent to the Bit Insertion. Oppo-site operation occurs at the Rx side.

• Fig.21 – 4x2 Mbit/s multiplexing. The mux aggregates the four 2 Mbit/s tributaries generating a8448 kbit/s frame as per Recc. G.742. The multiplexed signal is then sent to the Bit Insertion. Op-posite operation occurs at the Rx side.

• Fig.22 – 8x2 Mbit/s multiplexing. The eight 2 Mbit/s tributaries are grouped in two 4x2 Mbit/s groupseach of one generating a G742 frame structure at 8448 kbit/s to be sent to the next Bit Insertion.Opposite operation occurs at the Rx side.

• Fig.23 – 16x2 Mbit/s multiplexing. The sixteen 2 Mbit/s tributaries are grouped in four 4x2 Mbit/sgroups each of one generating a G.742 frame structure at 8448 kbit/s. A further multiplexing of theachieved four 8448 kbit/s streams will generate a frame structure at 34368 kbit/s as per Recc.G.751. This latter is to be sent to the Bit Insertion. Opposite operation occurs at the Rx side.

The multiplexed tributaries are then sent to the B.I. for aggregate frame generation.

The aggregate frame contains:

34 AL - MN.00142.E - 009

• the main signal from the MUX(s)

• the framed service signal from the service interface

• the EOC signals for supervision message propagation towards the remote terminal

• the frame alignment word

• the bits dedicated to the FEC.

All the synch. signals to perform multiplexing (demultiplexing) and BI (BE) process are achieved from a x0at 40 MHz. The aggregate frame thus generates is sent to the QAM modulator.

Rx side

Refer to Fig.24.

At Rx side the Bit extraction separates the main multiplexed signal from the service signal and then aftera proper demultiplexing process (opposite to that previously described at the Tx side) sends them to theoutput interfaces.

8.1.2 Radio interface

This functionality provides the following:

• QAM modemodulation

• power supply to IDU and ODU

• telemetry IDU/ODU

• cable interface

QAM modemodulation – Modulation side

See Fig.25

The aggregate signal from the BI undergoes the following process in digital form:

• serial to parallel conversion

• differential encoding

• generation of the shaped modulating signals feeding the IF part of the QAM modulator.

This latter comprises:

• recovery low pass filter to eliminate signal periodicity

• 330 MHz local oscillator

• a 90° phase shifter to supply two mixers with two in quadrature carriers

The thus obtained 330 MHz QAM modulated carrier is then sent to the cable interface for connection withODU.

QAM modemodulation – Demodulation side

See Fig.25.

The 140 MHz modulated carrier from the ODU is reaching the IDU through the cable interface.

The connection to the demodulator input is made via a cable equalizer for cable loss compensation.

The IF section of the QAM demodulator extracts the I and Q analogue signals then digital converted for thefollowing processing:

• clock recovery

AL - MN.00142.E - 009 35

• baseband equalisation and filtering

• bit polarity decision

• differential decoding

• parallel to serial conversion to recover the aggregate signal.

The aggregate signal is then sent to a frame alignment circuit and CRC analysis and then to the error cor-rector to achieve the BER extimate, the PM and HBER/LBER alarms.

Power supply

Refer to Fig.25. The –48 V battery voltage feeds the IDU and ODU circuitry. The service voltages for theIDU feeding are achieved through a DC/DC converter for +3.6 V generation and a step down circuit for –5V.

Both voltages are protected against overvoltages and overcurrents. The power to the ODU is given by thesame battery running through the interconnection cable. A breaker protects the battery against cable fail-ure.

Telemetry IDU/ODU

Refer to Fig.19 and Fig.25. The dialogue IDU/ODU is made–up by the main controller and associated pe-ripherals within the ODU. Controls for ODU management and alarm reporting is performed making use ofa 388 kbit/s framed signals. The transport along the interconneting cable is performed via two FSK mod-ulated carriers: 17.5 MHz from IDU to ODU; 5.5 MHZ from ODU to IDU.

Cable interface

Refer to Fig.25. This circuit permits to communicate to the far ODU through the interconnecting cable. Itis mainly made up of a set of filters that:

• combine the 330 MHz, QAM modulated carrier/the 17.5 MHz carrier/the power supply

• separate the 140 MHz QAM modulated carrier and the 5.5 MHz carrier

8.1.3 Equipment controller

The controller functionality performs the following:

• houses the equipment software for equipment management

• interfaces the SCT/LCT program through supervision ports

• receive external alarms and route them to relay contacts along with the internal alarms generatedby the equipment.

The equipment software permits to control and manage all the equipment functionality. It is distributed ontwo hardware levels: main controller and ODU peripheral controller. The dialogue between main and pe-ripheral controllers is shown in Fig.26.

Main controller

The activities executed by the main controller are the following:

• Communication management: it makes use of SNMP as management protocol and IP or IP over OSIas communication protocol stacks. See Fig.27 for details. The interface ports for the equipmentmanagement are the following:

- LAN Ethernet 10BaseT

• Log–in: the main controller manages the equipment or network login/logout by setting and thencontrolling the user’s ID and relevant password.

• Database (MIB): validation and storing in a non–volatile memory of the equipment configurationparameters.

• Equipment configuration: distribution of the parameters stored in the MIB towards the peripheralµPs for their attuation in addition to the controls from user not stored in the MIB (i.e. loops, manualforcing etc...).

• Alarm monitoring: acquisition, filtering and correlation of the alarms gathered from slaved µPs. Lo-cal logger and alarm sending to the connected managers: SCT/LCT – NMS5UX. Management of thealarm signalling on the LIM front panel.

• Performances: PM management as per Recc. G.828.

• Download: the main controller is equipped with two flash memory banks containing the running pro-gram (active bank) and the stand–by program (inactive bank). This permits to download a new soft-ware release to the inactive bank without distributing the traffic. Bank switch enables the new release to be used. Download activity is based on FTP protocol which downloads application programs, FPGA configu-ration, configuration files on main controller inactive bank or directly on the peripheral controllers.

Peripheral controllers

The peripheral controllers take place within the ODU and are slaved to main controller with the task of ac-tivating controls and alarm reporting of dedicated functionality.

8.2 IDU LOOPS

To control the IDU correct operation a set of local and remote loops are made available. The commandsare forwarded by the LCT/SCT program. Loop block diagram is shown by Fig.28.

8.2.1 Tributary loop

Tributary local loop

Each input tributary is routed directly to the trib. output upon receiving the command from the LCT. TheTx line transmission is still on.

Tributary remote loop

Each tributary directed towards the Rx output line is routed back to the Tx line. The Rx line is still on.

8.2.2 Baseband unit loop

This kind of loop is only local and is activated at BI/BE level. Tx line is still on.

AL - MN.00142.E - 009 37

8.2.3 IDU loop

This kind of loop permits to check the full IDU digital operation.

9 DESCRIPTION OF THE INDOOR UNIT – ETHER-NET INTERFACES

The indoor unit can be provided with Ethernet module. In this way the equipment has both 2 Mbit/s andEthernet ports, and the bit rate assigned to Ethernet traffic is the nominal capacity of the radio minus en-abled tributaries.

Description that follows covers Ethernet signal treatment, 2 Mbit/s signal treatment has been described inprevious chapter.

9.1 TREATMENT OF ETHERNET SIGNALS

In the place of V11 or (V28 + RS232) board it is possible to have Ethernet Module.

In this way the IDU is equipped with the following interfaces:

• 3x electrical interface Ethernet 10/100 BaseT IEEE 802.3

• 16 E1 interfaces in ALC

• 32 E1 interfaces in ALC plus

• total capacity from 4 to 64 Mbit/s (ALC) or from 4 to 105 Mbit/s (ALC plus)

Most important functions are:

• multiplexing of 2 Mbit/s tributaries

• concatenation of 2 Mbit/s streams

• LAPS Link Access Procedure SDH (ITU X.86) for concatenated 2 Mbit/s

• bridge/switch between a local LAN port and the radio LAN port

• MAC switching

• MAC address learning

• MAC address ageing

• Ethernet interface with autonegotiation 10/100, full duplex, half duplex

- Ethernet interface with Flow Control, Back Pressure, MDI/MDX crossover

• network segmentation into bridge

• virtual LAN as per IEEE 802.1q (anyone from 0 to 4095 VID for a maximum of 64 memory location)(see Fig.30)

• layer 2 QoS, priority management as per IEEE 802.1p (see Fig.30)

• layer 3 ToS/DSCP (see Fig.33)

• packet forwarding

A block diagram of IDU with Ethernet module can be found into Fig.29.

In the IDU with Ethernet module there is a "switch" with 3 external ports and 1internal ports. External portsare electrical Ethernet 10/100BaseT interfaces placed on the front panel. Internal port is connected to radioside stream.

Ethernet traffic coming from external ports goes to internal port radio side. The radio side port is connectedto streams group of concatenated 2 Mbit/s.

46 AL - MN.00142.E - 009

The concatenated 2 Mbit/s are assembled in a protocol called LAPS similar to HDLC.

In Tx side Ethernet traffic is packet into a protocol called LAPS similar to HDLC. The resulting stream isdivided into the used number of 2 Mbit/s streams. The 2 Mbit/s streams are then multiplexed, togetherwith 2 Mbit/s arriving from front panel, the resulting stream goes to the modulator, see Fig.29.

In Rx the stream arriving from the demodulator is divided into the 2 Mbit/s streams, then the 2 Mbit/s notused into the front panel 2 Mbit/s are concatenated and sent to Ethernet circuits. Resulting stream, afterLAPS protocol control, is sent to switch internal port.

9.1.1 2 Mbit/s tributaries

Tributary channels at 2 Mbit/s (E1), connected to relevant connectors into front panel, are multiplexed asinto standard IDU, see previous chapter.

From 0 to 16 tributaries can be selected to be used via SCT/LCT program, all the other available 2 Mbit/sare sent to switch internal port.

9.1.2 Electrical Ethernet interface

The electrical Ethernet/Fast Ethernet interfaces are type IEEE 802.3 10/100BaseT with RJ45 connector. Forinput or output signals at RJ45 please refer to User connection chapter. Cable can be UTP (UnshieldedTwisted Pair) or STP (Shielded Twisted Pair) Category 5.

Standard coding:

• Ethernet 10 Mbit/s: Manchester

• Fast Ethernet 100 Mbit/s: MLT–3 ternary

EMC/EMI protection:

• Input and output pins are galvanically isolated through a transformer

• to reduce EMI every pin at RJ45 connector is terminated even if not used

• two signal lines are equipped with low capacity secondary protection to sustain residuals of possibleelectrostatic discharges (ESD).

With LCT/SCT program it is possible to activate autonegotiation (speed/duplex/flow control) on10/100BaseT interface.

9.1.3 Front panel LEDs of Ethernet ports

There are 2 Leds for any Ethernet interface:

• DUPLEX: color green, On = full duplex, OFF = half duplex

• LINK/ACT: color green, ON = link up without activity, OFF = link down, BLINKING = link with activityon Rx and Tx.

9.1.4 Bridge/switch function

A radio link equipped with Ethernet module can operate like a bridge/switch between two or more sepa-rated LANs with the following advantags:

AL - MN.00142.E - 009 47

• to connect two separated LANs at a distance even greater than the maximum limits of 2.5 km (forEthernet)

• to connect two LANs via radio within a complex digital network

• to keep separated the traffic into two LANs towards MAC filtering to get a total traffic greater thantraffic in a single LAN.

The bridge realized into Ethernet module is a transparent bridge (IEEE 802.1 part D) into the same Vlandescribed by VLAN Configuration Table.

The bridge works at data link level, Layer 2 of OSI pile, and leave untouched Layer 3.

The bridge takes care to sendo traffic from a local LAN, to remote LAN. Routing is only on the basic of Level2 addresses, sublevel MAC.

The operation of bridge is the following:

• when a bridge interface receives a MAC frame, the bridge on the basis of destination address, de-cides which LAN to send it

• if destination address is on originating LAN the frame is descarded

• if destination address is a known address (towards address learning procedure) and is present intolocal address table the frame is sent only on destintion LAN (MAC switching)

• otherwise the frame is sent to all ports with the same VLAN ID (flooding).

A bridge is very different from a repeater, which copies slavishly everything that receives from a line onall the others. The bridge, in fact, acquires a frame, analyzes it, reconstruct it and routes it. The bridgecompensates also the different speeds of the interfaces, therefore an input can be at 100 Mbit/s and outputat 10 Mbit/s.

The mechanism is the following:

• from the moment of its activation, the bridge examines all the frames that arrive it from differentLANs, and on these basis it builds its routing tables progressively. In fact, every received frame allows the bridge to know on what LAN the sending station is located(MAC address learning).

• every frame that arrives to the bridge is rebroadcasted:

- if the bridge has the destination address into the routing table, sends the frame only into thecorresponding LAN

- otherwise the frame is sent to all the LANs except the originating (flooding)

- as soon as the bridge increases its knowledge of different machines, the retransmission becomesmore and more selective (and therefore more efficient)

• the routing tables are updated every some minutes (programmable), removing addresses not alivein the last period (so, if a machine is moved, within a few minute it is addressed correctly) (MACaddress ageing).

The whole process of bridging is restricted to the ports which are members of the same Vlan as describedinto Vlan Configuration Table.

9.1.5 Ethernet Full Duplex function

The first realizations of the Ethernet network were on coaxial cable with the 10Base5 standard.

According to this standard Ethernet interfaces (e.g. PC) are connected to the coaxial cable in parallel andare normally in receiving mode. Only one PC, at a certain time, transmits on the cable, the others are re-ceiving, so this is half duplex mode, and only one PC uses the recived message.

Then the coaxial cable was progressively replaced by the pairs cable Unshielded Twisted Pair (UTP) as per10BaseT standard. Normally there are four pairs into UTP Cat5 cable but two pairs are used with 10BaseT,one for Tx one for Rx. Into 10Base5 and 10BaseT standards, network protocols are the same the differencelays into the electrical interface. UTP cable is connected point to point betwen a hub and a Ethernet inter-face. Network structure is a star where the server is connected to a hub and from this a UTP cable is laiddown for each Ethernet interface starts.

48 AL - MN.00142.E - 009

The further step is to replace the hub with a more powerful equipment, e.g. a switch. In this case it ispossible to activate transmission on both pairs at the same time, on one twisted pair for one direction, onthe other pair for opposite direction. Thus we obtain full duplex transmission on UTP.

Activating full duplex transmission it is possible to obtain a theoretical increase of performance of nearly100%. Full duplex mode can be activated into 10/100BaseT interfaces manually or with autonegotiation100BaseFx operates always into full duplex mode.

9.1.6 Link Loss Forwarding

Link Loss Forwarding (LLF) is an alarm status of ethernet interface.

LLF can be enabled or disabled. If LLF is enabled an US radio alarm condition will generate the alarm statusof Ethernet interface blocking any transmission to it. LLF can be enabled for each 3 ports at front panel.With LLF enabled the equipment connected (routers, switches so on) can be notified that radio link is notavailable and can temporarerly reroute the traffic.

9.1.7 MDI/MDIX cross–over

The Ethernet electrical interface can be defined by SCT program as MDI or MDIX to cross–over betweenpairs so that external cross–over cable is not required.

9.1.8 VLAN functionality

LIM Ethernet module works with IEEE 802.1q and 802.1p tag for VLANs and QoS see Fig.30.

The virtual LAN (VLAN) are logical separated subnets so that all the stations, into VLAN, seem to be intothe same physical LAN segment even if they are geographically separated.

The VLAN are used to separate traffic on the same physical LAN too. Station operating on the same physicalLAN but on different VLAN work in separated mode thus they do not share broadcast and multicast mes-sages. This results in a reduction of broadcast generated traffic and above all we get more security thanksto network separation.

Tag position and structure are shown into Fig.30.

Tag is made up with:

• a fixed word of 2 bytes

• 3 bits for priority according 802.1p

• 1 fixed bit

• 12 bits VLAN identifier (VLAN ID) according 802.1q.

Switch crossconnections are based on Vlan Configuration Table where input and output ports or only outputports should be defined for any used VID.

Vlan Configuration Table has 64 position for Vlan ID range from 1 to 4095.

9.1.9 Switch organized by port

For each input port it is possible to define where to route the incoming traffic; one or more of the 3 otherports can be Enabled to exit the incoming traffic. It is possible, also, to route back the incoming traffic into

AL - MN.00142.E - 009 49

the same port. This type of connection are monodirectional. For a dibirectional connection between a ge-neric Lan A and Lan B it is necessary to set the connection from Lan A to Lan B and from Lan B to Lan A.

The IDU with Ethernet module has 3 physical ports and one internal port, radio side. The internal switchcan connect two or more ports together.

Then MAC address bridging rules will be applied to this packet. It is possible to select that a packet followsthe description of Vlan Configuration Table for its Vlan ID.

Another selection is to follow only Vlan Configuration Table.

Packets can exit from a port as Unmodified or all Tagged either all Untagged. Unteggad packets will takedefault tags.

For output operations there are 3 selections:

• Unmodified: tagged packets keep their tag. Untagged packets remain untagged

• Tagged: all the packets will exit tagged, tagged packets keep their tag, untagged packets take De-fault VID of incoming port.

• Untagged: all the packets will exit untagged.

9.1.10 Switch organized by VLAN ID

Vlan Configuration Table

Vlan Configuration Table defines a list of Vlan ID, For any Vlan ID some ports are members of Vlan othersare not members. Ports members of a Vlan are allowed to receive and send packets with that Vlan. Switchdinamically assignes packets to the output port according their VLAN ID.

Packets aren’t sent out to that port unless they belong to one of the Vlan of which the port is a member.

A port can be a member of a Vlan or many Vlan.

A port can be a member from 1 to 64 Vlans but tagged packets are dropped if their input port is not amember of packet’s Vlan.

After the control of packet and port Vlan membership MAC address bridging rules will be applied to thispacket.

Ingress Filtering Check

This is a process to check an incoming packet to compare its Valn ID to input port’s Vlan membership. WithIngress Filtering Check it is possible to permit only to tagged packets to enter the switch. If the port is notmember of the Vlan n. XX all the incoming packets with Vlan ID XX will be dropped.

There are 3 option into Ingress Filtering Check to manage incoming packets:

• Disable: all Tagged and Untagged packets can transit into the switch following setting of swicth or-ganized by port.

• Fallback: Untagged frames follow the rules of switch organized by port, Tagged frames with Vlan IDdescribed into the Vlan Configuration Table follow the rules of the table, Tagged frames with VlanID not described into the Vlan Configuration Table follow the rules of switch organized by port.

• Secure: Untagged frames cannot enter the switch, Tagged frames with Vlan ID described into theVlan Configuration Table follow the rules of the table, Tagged frames with Vlan ID not described intothe Vlan Configuration Table cannot enter the switch.

Operations at the input. At the input port the packet is received and a switching decision must be made.The switch analyse the Vlan ID (if present) and decides whether and where to forward the frame. If thereceived packet is untagged, the switch sends the packet to the port specified into incoming port "Lan perport" settings. If the packet is tagged the switch check the other 3 destination ports to find at least onewith the same Vlan ID and put the packet into output port queue. If the Vlan ID is not listed into VlanConfiguration Table the switch sends the packet to the port specified into incoming port "Lan per port" set-tings.

50 AL - MN.00142.E - 009

Then MAC address bridging rules will be applied to this packet.

Operations at the output. For each output port there are 3 selections for outgoing packets.

• Disable output port

• Enable unchanged: tagged packets keep their tag. Untagged packets remain untagged.

• Enable tagged: all the packets will exit tagged with Vlan ID specified into Vlan Configuration Table,tagged packets keep their tag, untagged packets take Default VID of incoming port.

• Untagged: all the packets will exit untagged.

9.1.11 Layer 2, Priority function, QoS, 802.1p

Some services as voice overIP and videoconference have some time limits to work properly. A solution isto increase the priority of time sensitive packets. In this case random crowding coming from other servicesaffects the delay of prioritized packets a lot less.

Into LIM Ethernet module different priority of incoming packets is managed using Tag defined into IEEE802.1p (see Fig.30).

Every switch output port holds 4 output queues: queue 4 has highest priority, queue 0 has the lowest pri-ority (see Fig.31).

Priority can be organized by incoming port or by incoming priority tag:

• Priority by incoming port. For Untagged packets at each input ports it is decided to send the packetsto one of the 4 queues of output ports defining which is the Default Priority Queue: Queue = 0, 1,2, 3. For Tagged packets it is necessary to Disable Priority so they will go in the same queue ofUntagged packets.

• Priority by incoming priority. For tagged packets for each priority tag (3 bits = for 7 priority levels)it is possible to define where to send the packets, into Queue from 0 to 3. Priority must be enableon 802.1p mode only or IpToS mode only (see next paragraph) or first check 802.1p mode andIpToS mode either first check IpToS mode only (see next paragraph) or first check 802.1p modeand IpToS mode either first check IpToS mode and then 808.1q. For untagged packets the priorityis defined only by incoming port.

Outgoing packet policy at output ports can be WFQ (Wait Fair Queue) with fixed proportional output policy8 packets from Queue 3, 4 from Queue 2, 4 from Queue 1, 1 from Queue 0.

Layer 3, Priority function, QoS, IP–V4 ToS (DSCP)

Only for IP packets it is possible to use incoming Layer 3 ToS (see Fig.32) to prioritize incoming packets.The 8 bits available can be read as 7 bits of ToS or 6 bits of DSCP as shown in Fig.33.

According priority defined into ToS/DSCP the packet is sent into high priority queue low priority queue ofoutput ports.

With SCT/LCT program it is possible to select a different output queue for any ToS/DSCP priority level ateach input port.

11 DESCRIPTION OF THE OUTDOOR UNIT

11.1 GENERAL

The 1+0 ODU (refer to Fig.34) consists of a two aluminium shell mechanical structure, one shell housingall the ODU circuits, the other forming the covering plate.

Two ODU versions are available and are pointed out in the following description if it is necessary. The twoODU versions differ in Tx power and dimensions.

On the ODU are accessible:

• the "N" type connector for cable interfacing IDU and ODU

• the "BNC" connector for connection to a multimeter with the purpose to measure the received fieldstrength

• a ground bolt.

The 1+1 hot stand–by version (refer to Fig.35) consist of two 1+0 ODUs mechanically secured to a struc-ture housing the hybrid for the antenna connection.

11.2 TRANSMIT SECTION

Refer to block diagram shown in Fig.36.

The 330 MHz QAM modulated carrier from the cable interface (see chapter 11.4) is forwarded to a mixerpassing through a cable equalizer for cable loss compensation up to 40 dB at 330 MHz. The mixer and thefollowing bandpass filter give rise to a second IF Tx carrier the frequency of which depends on the go/returnfrequency value. The mixer is of SHP type.

The IF Tx frequency is μP controlled. Same happens to Rx IF and RF local oscillators. This latter is commonto both Tx and Rx sides.

The IF carrier is converted to RF and then amplified making use of a MMIC circuit. The conversion mixer isSSB type with side band selection.

The power at the MMIC output can be manually attenuated, 1 dB step.

The automatic adjustment is performed making use of an ATPC (see paragraph 11.5 for details).

The regulated output power is kept constant against amplifier stage gain variation by a feedback includingthe AGC.

Before reaching the antenna side the RF signal at the output of MMIC passes through the following circuits:

• a decoupler plus detector diode to measure the output power

• a circulator to protect the amplifier stages against possible circuit mismatch.

• a ON/OFF switch for 1+1 operation

• an RF bandpass filter for antenna coupling.

An RF coupler plus a detector and a shift oscillator made up the RF loop which is enabled upon receiving aμP control. The RF loop permits the Tx power to return back to receive side thus controlling the total localradio terminal performance.

AL - MN.00142.E - 009 57

11.3 RECEIVE SECTION

The RF signal from the Rx bandpass filter is sent to a low noise amplifier that improves the receiver sen-sitivity.

The following down–converter translates the RF frequency to approximately 765 MHz.

The conversion mixer is SSB type. The sideband selection is given through a μP control.

A second down converter generates the 140 MHz IF carrier to be sent to the demodulator within the IDU.The level of the IF carrier is kept constant to –5 dBm thank to the IF amplifier stages, AGC controlled,distributed in the IF chain. In addition the AGC gives a measure of the receive RF level.

Between two amplifiers a bandpass filter assures the required selectivity to the receiver. The filter is SAWtype and the bandwidth depends on the transmitted capacity.

11.4 CABLE INTERFACE

The cable interface permits to interface the cable interconnecting IDU to ODU and viceversa.

It receives/transmits the following signals:

• 330 MHz (from IDU to ODU)

• 140 MHz (from ODU to IDU)

• 17.5 MHz (from IDU to ODU)

• 5.5 MHz (from ODU to IDU)

• remote power supply.

The 17.5 MHz and 5.5 MHz FSK modulated carriers, carry the telemetry channel. This latter consists of two388 kbit/s streams one from IDU to ODU with the information to manage the ODU (RF power, RF frequen-cy, capacity, etc...) while the other, from ODU to IDU, sends back to IDU measurements and alarms of theODU. The ODU management is made by a μP.

11.5 ATPC OPERATION

The ATPC regulates the RF output power of the local transmitter depending on the value of the RF level atthe remote terminal. This value has to be preset from the local terminal as threshold high and low. Thedifference between the two thresholds must be equal or higher than 3 dB.

As soon as the received level crosses the preset threshold level low (see Fig.39) due to the increase of thehop attenuation, a microP at the received side of the remote terminal sends back to the local terminal acontrol to increase the transmitted power. The maximum ATPC range is 40 dB.

If the hop attenuation decreases and the threshold high is crossed then the control sent by the microPcauses the output power to decrease.

ATPC range can be reduced from the maximum value to 0 dB, by 1 dB step, consequently to a reductionof the output maximum power through an adjusted attenuation.

58 AL - MN.00142.E - 009

11.6 1+1 Tx SYSTEM

The two ODUs are coupled to the antenna side via a balanced or unbalanced hybrid.

1+1 Tx switching occurs in the 1+1 hot stand–by 1 antenna or 2 antennas versions as shown in Fig.37 andFig.38.

The transmitter switchover is electromechanic type and consists of two ON/OFF switches within the twoODUs that assure at least 40 dB insulation on the stand–by transmitter.

Transmit alarm priority is shown in Tab.12.

Tab.12 - Transmit alarm priority

11.7 POWER SUPPLY

The battery voltage is dropped from the cable interface and then sent to a DC/DC converter to generatethree stabilized output voltages to be distributed to the ODU circuitry:

• +3.5 V

• a voltage comprised between +6.2 V and +8.2 V to power amplifiers operating at different frequen-cy bands

• a –12 V through an inverter circuit.

Each voltage is protected against overcurrent with automatic restart.

Protection against overvoltage occurs as soon as the output voltage raises more than 15% respect to thenominal voltage. The restart is automatic.

Section 4.LINE-UP

21 LINE–UP OF THE RADIO HOP

21.1 LINE–UP OF THE RADIO HOP

The line–up consists of the following steps:

• on site radio terminal installation (perform user connections and ODU installation as described inthe relevant chapters)

• equipment switch–on (operate the ON/OFF switch on the IDU front)

• antenna alignment for maximum received RF signal level

• network element configuration

• check measurements.

21.1.1 Antenna alignment and received field measurement

Purpose of antenna alignment is to maximize the RF received signal level.

Proceed as follows:

• connect a multimeter to BNC connector on the ODU for AGC measurement

• adjust antenna pointing as soon as the maximum AGC voltage value is achieved.

The relationship between AGC voltage and received field is shown by Fig.98.

The received field level has a tolerance of ±4 dB in the full temperature range.

144 AL - MN.00142.E - 009

21.1.2 Network element configuration

A factory default address is assigned to each network element that must normally be reconfigured on sitefollowing the network administrator rules.

To this purpose it is required to connect the PC, where the SCT/LCT program has been installed, to thenetwork interfaces.

This has to be done via USB or Ethernet cable.

22 LINE–UP OF ETHERNET TRAFFIC (FOR IDU WITH ETHERNET MODULE ONLY)

22.1 GENERAL

This paragraph deals with line–up of V12252 Ethernet module with details of SCT/LCT program related onlyto Ethernet application.

Assuming that the radio link is already in service, with correct frequency, output power and correct antennaalignment, the line up procedure for different kinds of connection set up of a radio link AL, equipped withLIM Ethernet/2 Mbit/s module, is hereafter described:

1. Local Lan–1 port to remote Lan–1 port connection LAN per port, see Fig.99

2. Local Lan–1 port to remote Lan–1 port connection with only VLANs

3. 3 to 1 port connections, see Fig.111.

Settings here below are intended to be done both into local and remote radio equipment.

22.2 LOCAL LAN–1 PORT TO REMOTE LAN–1 PORT (TRANSPARENT CONNECTION LAN PER PORT)

Settings for Untagged and Tagged Traffic

Fig.99 - Local Lan–1 port to remote Lan–1 port connection

The line–up of Ethernet traffic is made with the help of SCT/LCT program.

Please refer to Fig.100. First selection is Ethernet throughput and modulation scheme, in this example weselect 16 Mbit/s and modulation 16QAM (max throughput and modulation scheme depend on terms of li-cence provided by Siae Microelettronica).

Select configuration 1+0 or 1+1 according system requirements. Inside LCT, select Tributary window. If 2Mbit/s tributaries are needed, inside the Tributary window it is possible to activate a 2 Mbit/s input/outputon the front panel. When the activation of required 2 Mbit/s tributaries is completed, all the others 2 Mbit/sstreams are automatically used for the Ethernet traffic. For instance with a 8x2 Mbit/s capacity, if we usetwo 2 Mbit/s the capacity assigned to Ethernet circuits is automatically set to 6x2 = 12 Mbit/s full duplex.

Fig.100 - Selection of Ethernet Throughput

See Fig.101 for General settings for the switch. All the used ports must be Enabled, so enable Lan–1 andInternal Port, see Fig.102.

The other ports should be disabled. The correct cable crossover arrangement must be selected too (seeFig.102). At the end of Line–up, enable LLF if needed.

For Untagged traffic, connections are done with Lan per port selections. Referring to Fig.103 incoming traf-fic at Lan–1 exits at Internal Port and into Fig.105 incoming traffic at Internal Port exits at Lan–1 port. Thisconnection are done for all Untagged traffic and all Tagged packets with Vlan Id not described into VlanConfiguration Table.

If Vlan Configuration Table is blank all Tagged traffic follows the rules of Lan per port.

Possible selections of Ingress Filtering Check:

1. Disable 802.1q: no check of Virtual Lan tag is made and all packets follow Lan per port settings

2. Fallback: if Tagged packets have their Vlan Id into Vlan Configuration Table they follow the connec-tion described into the table, otherwise they follow the Lan per port settings as Untagged packets

3. Secure: no Untagged packet transits; only Tagged packets with Vlan Id listed into the table cantransit. For all pass configuration, Disable 802.1 should be selected. With Egress Mode as Unmodified the outgoing packets at Lan–1 port exit Untagged or Taggedexactly as they were Untagged or Tagged at the incoming port.

22.3 LOCAL LAN–1 PORT TO REMOTE LAN–1 PORT (WITH VLANs)

Settings are done to transfer only Tagged traffic within Vlans.

We want that Vlan 701, 702, 710 and 1, 2, 3 can pass into the radio link and all the other Tagged or Untaggedpackets should be blocked.

The line up of Ethernet module is made with the help of LCT/SCT program. Please refer to Fig.100. First selec-tion is Ethernet throughput and modulation scheme, in this example we select 16 Mbit/s and modulation 16QAM(max throughput and modulation scheme depends on terms of licence provided by Siae Microelettronica). Se-lect configuration 1+0 or 1+1 according system requirements.

Inside LCT, select tributary window. If 2 Mbit/s tributaries are needed, inside the tributary window it is possibleto activate a 2 Mbit/s input/output on the front panel. When the activation of required 2 Mbit/s tributaries iscompleted, all the others 2 Mbit/s streams are automatically used for the Ethernet traffic. for instance with a16 Mbit/s capacity if we use two 2 Mbit/s the capacity assigned to ethernet circuits is automatically set to 16–2x2 = 12 Mbit/s full duplex.

See Fig.101 for general settings for the switch. All the used ports must be enabled, so enable Lan–1 and InternalPort, see Fig.102. The other ports should be disabled. The correct Cable crossover arrangement must be se-lected too. Enable LLF if needed, only at the end of line up.

Vlan settings for Lan–1 and Internal Port should be like in Fig.107 with Ingress Filtering Check as Secure andEngress Mode as Tagged. With this setting only Tagged packets with Vlan ID listed into the Vlan ConfigurationTable can transit. All Untagged packets are blocked at the incoming port and outgoing Tagged packets don’tchange.

A packet with Vlan ID XX can enter into the switch only if Incoming Port (Ingress port) is a member of the VlanXX, same packet will exit only from ports (Engress Port) which are members of Vlan XX. Vlan membership isdescribed into Vlan Configuration Table. A port can be member of no one, one or more Vlans. See Fig.108 forVlan Configuration Table settings for our example.

Fig.107 - Virtual Lan input and output settings at Lan–1 port

152 AL - MN.00142.E - 009

Fig.108 - Vlan Configuration Table with some Vlans

Tagged incoming packet can be treated with FIFO policy or on the basis of their 802.1p priority tag andToS/DSCP value for IP packets. There are 4 queue at each output port. The decision about to which outputqueue to send a packet is defined into Ethernet switch window selections for 802.1p tag. Into Ethernetswitch window it is possible to select ToS/DSCP button to open window ToS/DSCP, in this window eachincoming ToS/DSCP value is associated with an output queue so it is possible to change the priority of theincoming packet.

When no info on priority is available, the packet is sent to Default Priority Queue using FIFO policy.

Into Lan–1 window select Priority (802.1q), into priority box there are some selections: with "Disable"switch doesn’t look at priority tag; with 802.1p switch looks at Tag 802.1p only; with IpToS for IP packetsonly switch looks to ToS/DSCP identifier (into IP frame) only; with 802.1p – IpToS switch looks first to802.1p tag and secondly to ToS/DSCP, see Fig.110; with IpToS–802.1p switch looks first to ToS/DSCP andsecondly to Tag 802.1p.

Note: with IpToS switch looks to IP packet and ToS/DSCP doesn’t matter if the packets are tagged with802.1p or not.

In this example incoming tagged are tagged and it is necessary to transfer the packets with no change sothey must exit from output ports tagged, see Fig.109 and Fig.110.

22.4 3 TO 1 PORT CONNECTIONS

Fig.111 - 3 to 1 port connections

In this example 3 local port must communicate with corresponding remote ports. All the ports share thesame radio channel but traffic originated and directed to Lan1 should be kept separated from traffic fromLan2 and Lan3 and viceversa.

Lan–1 to Lan–1 connection should transfer tagged packets with Vlan 1, 701, 760 and untagged packets.Unspecified tagged packets must be stopped. Lan–2 and Lan–3 have the same requirements. For all con-nections IP packets with high priority TOS should transferred at minimum delay.

22.5 3 TO 1 PORT CONNECTIONS, SETTINGS FOR UNTAGGED TRAF-FIC

The line–up of Ethernet traffic is made with the help of LCT/SCT. Please refer to Fig.99.

First selection is Ethernet throughput and modulation scheme, in this example we select 16 Mbit/s andmodulation 16QAM (max throughput and modulation scheme depend on terms of licence provided by SiaeMicroelettronica). Select configuration 1+0 or 1+1 according system requirements.

Inside LCT, select Tributary window.

If 2 Mbit/s tributaries are needed, inside the tributary window it is possible to activate a 2 Mbit/s input/out-put on the front panel. When the activation of required 2 Mbit/s tributaries is completed, all the others 2Mbit/s streams are automatically used for the Ethernet traffic. For instance with a 8x2 Mbit/s capacity ifwe use two 2 Mbit/s the capacity assigned to Ethernet circuits is automatically set to 6x2 = 12 Mbit/s fullduplex.

Vlan Configuration Table will be defined in order to group traffic from Lan–1, Lan–2, Lan–3 to Port1. All theused ports must be Enabled.

Untagged traffic transits only if the selection for Ingress Filtering Check is disabled at each input port anda separated Vlan for Untagged traffic is set up for each port. See Fig.101, Fig.102, Fig.111, Fig.112 andFig.113.

Each port of the switch must be associated with a different Default VLAN ID in order to maintain the trafficcoming from different separated LANs, Lan–1 with default VID 3301, Lan–2 with default VID 3302, Lan–3with default VID 3303, for Lan–1 see Fig.113 and Fig.114.

The correct Cable Crossover arrangement must be selected too.

With the above settings inside the VLAN configuration Table only Untagged traffic is forwarded accross thebridge.

The same settings should be done inside the remote equipment. The above example shows the Virtual LanConfiguration Table in case of a link carrying the traffic of 3 independent LAN’s connected to Lan–1, Lan–2, Lan–3, which is split at the remote end among the outgoing Lan–1, Lan–2, Lan–3 ports, while using acommon radio link.

To prioritize some IP packets with high ToS/DSCP value it is possible to open PToS/DSCP window fromEthernet switch window and select the values of ToS for which the packet is sent to high priority Queue,see Fig.115.

Vlan 3301, 3302, 3303 are allowed to exit at Port1with tags (Tagged). Different default Tag’s allow to

keep separate the traffic from Lan1, Lan2 andLan3 exiting at Port 1. At the remote end the traffic

is split and forwarded from Port1 to Lan1, Lan 2and Lan3 without Tag to preserve the original

22.6 3 TO 1 PORT CONNECTIONS, SETTINGS FOR TAGGED AND UN-TAGGED TRAFFIC

If we want VLAN with Tag 701, 702 and 703 to transit between Lan–1 and Port–1 it is necessary to definePort 1 and Lan 1 as members of VLAN1, 701, 760 (see Fig.116 for VLAN 701 and do the same for VLAN1,760).

The VLAN Configuration Table will look like Fig.117.

For Lan–2 and Lan–3 we cannot use the same Vlan if we want to maintain traffic from Lan 1, 2, 3 separated.We must change the number of incoming Vlan for instance of 1, 701, 760 use 2001, 2701, 2760 for Lan–2 and 3001, 3701, 3760 for Lan–3. Connected equipment to Lan–2 port should be reprogrammed to useVlan 2001, 2701, 2760.

Connected equipment to Lan–3 port should be reprogrammed to use Vlan 3001, 3701, 3760.

To prioritize Ip packets with high ToS/DSCP value it is possible to open PToS/DSCP window from Ethernetswitch window and select the values of ToS for which the packet is sent to high priority Queue 3, seeFig.115. The same should be done inside the remote equipment.

22.7 3 TO 1 CONNECTIONS: EXAMPLES OF PRIORITY MANAGEMENT

Example 1: To assign to Lan–1 and Lan–3 low priority and to Lan–2 high priority, while wanting Taggedand Untagged to be treated in a fair manner on each queue do as follow: select Priority Disable for Lan–1,Lan–2 and Lan–3; select Default Priority Queue equal to Queue 0 for lan–1 and Lan–3 (see Fig.104). SelectDefault Priority Queue equal to Queue 3 for Lan–2 (as in Fig.118).

Outgoing Untagged packets will take priority tag defined into input port, in this case 0. Tagged frames keeptheir tag.

Example 2: Wanting tagged frames to be treated according their actual priority and untagged packets withlow priority, all inputs should be configured as in Fig.Fig.119.

Layer 2 Priority assignment is not modified if inside the second folder of the Lan–X (1, 2, 3) configurationwindow Untagged Frame Egress Mode = Unmodified is selected as in Fig. Fig.120.

The following checks must be carried out:

• check of the transmitted power;

• check of the received field strength (the reading must match the value resulting from hop calcula-tions);

• check of bit error rate and hop performances.

For checking procedures, please refer to SCT/LCT program and relevant help–on line.

164 AL - MN.00142.E - 009

24 TROUBLESHOOTING

24.1 GENERAL

The AL equipment consists of the following replaceable parts:

• IDU

• ODU

Purpose of the troubleshooting is to pinpoint the faulty part and replace it with spare.

Warning: the replacement of a faulty IDU with spare causes the spare IDU to be re–programmed. To thepurpose refer to chapter 19 for the relevant procedure.

24.2 TROUBLESHOOTING PROCEDURE

Troubleshooting starts as soon as one of the following alarm condition: IDU/ODU/REM is switched ON onthe IDU panel from (see Fig.121) or alarm messages are displayed by managers SCT/LCT. Two methods are used to troubleshoot the cause of fault:

• loop facilities

• alarm message processing using the manager SCT/LCT

24.2.1 Loop facilities

The equipment is provided with different loops that help locate the faulty part.

Warning: the majority of loops causes the traffic to be lost.

The available loops are the following:

• local tributary loops: usually used to test the cables interfacing the equipment upstreams

• remote tributary loops: usually used to test the two direction link performance making use of anunused 2 Mbit/s signal.

• baseband loop: it permits to test the LIM circuits

• IDU loop: it permits to test the complete IDU (optional)

• RF loop: it permits to test the complete radio terminal.

AL - MN.00142.E - 009 165

24.2.2 Alarm messages processing

When an alarm condition occurs, the equipment generates a number of alarm messages that appear onthe SCT windows ie: log history area and equipment view current alarm. Investigation on the alarm mes-sage meaning permits to troubleshoot the faulty module.

Alarm message organisation

The alarms (traps) are organized as alarm grouping relevant to a specific functions performed by the equip-ment.

The alarm grouping is available only in the view current alarm submenu.

What follows is the list of the alarm grouping:

• COMMON – alarms which are not related to a specific part of the equipment but relevant to the linkas EOC radio link alarm or link telemetry fail. If these alarms are ON the link is lost. Investigationmust be made on a possible bad propagation or equipment failure. See the condition of the othersalarm grouping.

• LIM – This grouping may generate alarms for the following causes:

- external fault: tributary loss signal

- LIM failure: i.e. multiplexer/demultiplexer failure or modulator/demodulator failure.

• RIM – This grouping may generate alarms for the following causes:

- external fault: demodulator fail alarm and local ODU alarm are generated when the ODU be-comes faulty.

- RIM failure – power supply alarm along with cable short/open alarms or modulator/demodulatoralarms are activated.

• RT – This grouping may generate alarms for the following causes:

- external fault: Rx power low alarm is generated given by a bad propagation or by a faulty remoteterminal.

- ODU failure: PSU fail alarm or RF VCO alarm or RT IF alarm is activated. If this happens, replacethe ODU.

• UNIT – This grouping generates alarms when one of the units, the equipment consists of, is faultyor does not respond to the controller polling. Replace the faulty unit.

• CONTROLLER – There is not an alarm message relevant to a controller module failure. An alarmcondition causes Led IDU to steady lights up.
