2 FIRST AID FOR ELECTRICAL SHOCK AND SAFETY RULES
2.1 FIRST AID FOR ELECTRICAL SHOCK
Do not touch the bare hands until the circuit has been opened. pen the circuit by switching off the lineswitches. If that is not possible protect yourself with dry material and free the patient from the con-ductor.
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.
MN.00288.E - 004 7
Tab.1 - Artificial respiration
2.2 SAFETY RULES
When the equipment units are provided with the plate, shown in Fig.1, it means that they contain compo-nents electrostatic charge sensitive.
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 matter in mouth (den-
tures, 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 oxy-gen by taking deep breaths with your mouth open
4
With 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 patient’s chest heaves. This second method can be used instead 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 backwards 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 as-
certained his death.

7.1.2 Baseband processor
The baseband Processor (BBP) carries out the following operations:
• primary and secondary power supply
• line interfaces and protections
• baseband circuits and packets processing
• I and Q signals generation and sampling
• I, Q demodulator
• Rx baseband filtering
• Actuators and measurement points for RF unit
• FPGA debug connector
• FPGA
• Controller
BBP unit is different depending on the interface type (electrical or optical).
7.1.2.1 Firmware
Equipment software permits to control and manage all the equipment functionality and it is distributed ontwo hardware levels: main controller and ODU peripheral controllers.
Firmware can be updated through the Web Lct and it is stored in two different memory benches: one con-taining the running firmware and the other the stand-by firmware. This permits to download a new firm-ware release to the stand-by bench without cutting the traffic
Use “Bench Switch” to activate the bench in stand-by (SW restart will be performed).
There are 2 firmware versions for the ODU:
• ALFOplus80 “Stand alone”: radio full outdoor with transport of IP Ethernet traffic
• ALFOplus80 “split mount”: the ODU must be necessarily connected to the IDU AGS-H that it getsfull control of the ODU. The radio composed transports TDM (E1&STM1) and IP Ethernet traffic.
7.1.2.2 Web Lct
The Web Lct is a web interface software already present in the ALFOplus80, which requires Adobe FlashPlayer and allows the configuration and the management of the local radio, using LAN Port Management.When the remote one is configured properly, the whole link can be managed. WEB Lct runs on any browser(Internet Explorer or Firefox are recommended).
Web Lct console is a free software downloadable from the site www.siaemic.com after registration.
In order to transfer data it is necessary “Web LCT console” or “SCT” running.
7.1.3 RF Transceiver unit
RF Transceiver consists of the following functional blocks:
• power supply dedicated to microwave circuits
• Tx baseband filtering
• I, Q modulator
• frequency synthesizer
MN.00288.E - 004 31
• microwave transmitter and receiver
• IF devices on Rx side
7.1.4 Switch for Ethernet ports
Inside ALFOplus80 is present an Ethernet switch with 2 external ports line side (electrical 10/100/1000BaseT or optical 100/1000BaseFX), one internal radio port and one port towards controller (seeFig.12). Internal port is represented by the local radio stream where through native Ethernet transport isconnected with the remote equipment.
Fig.12 - ALFOplus80 block diagram
Switch function
ALFOplus80 can operate like a switch between two or more separated LANs with the following advantages:
• to connect two separate LANs
• 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 thanthe traffic in a single LAN.
By default the routing works on basis Mac Address (Layer 2), but it can be enabled on basis VLAN ID, inWeb Lct - Ethernet switch (Enh) - Common Parameters.
The operation is the following: when a LAN port receives a MAC frame, on the basis of destination address,it decides which LAN to send it:
• if destination address is on originating LAN the frame is discarded
• if destination address is a known address (towards address learning procedure) and is present intolocal address table, the frame is sent only on destination LAN (MAC switching)
• otherwise the frame is sent to all ports with the same VLAN ID (flooding).
Take account the value of Max Packet Size [byte] when “802.1Q setting” is set as DISABLE or FALLBACKthe switch adds 4 Bytes for internal S-Tag. With 802.1Q setting in SECURE (that means that packet VIDmust be contained in Virtual LAN table list, otherwise the packet is discarded), no internal TAGS are added.
Ethernet Speed/Duplex function
With electrical interface, in Web Lct - Baseband - Lan, Speed/Duplex can be manually or automaticallyactivated as half Duplex or Full Duplex 10/100/1000Base-T, while with optical interface, Speed Duplex canbe set as Full Duplex 100/1000Base-X.

Link Loss Forwarding
Link Loss Forwarding (LLF) is an alarm status of Ethernet interface. LLF can be enabled or disabled.
If LLF is enabled, any linkdown alarm will generate the alarm status of Ethernet interface blocking anytransmission to it. LLF can be enabled for each ports. With LLF enabled the equipment connected (routers,switches so on) can be notified that radio link is not available and can temporarily re-route the traffic.
MDI/MDIX cross-over
For each LAN interface, cross-over cable can be set in Web Lct - Baseband - Lan - Cable Crossover as:
• Auto - Lan recognizes automatically the connected cable type (Straight cable or Crossover cable)
• MDI (NIC) - Manual crossover wiring type T568A
• MDI-X (Switch) - Manual crossover wiring type T568B
With crossover cable it is necessary to use the same wiring format (MDI/MDI or MDI-x/MDI-x) on bothends. In case of straight cable is the opposite (MDI/MDI-x or MDI-x/MDI).
VLAN functionality
ALFOplus80 works with IEEE 802.1q and 802.1p tag. Tag is made up with:
• a fixed word of 2 bytes
• 3 bits for priority according with 802.1p
• 1 fixed bit
• 12 bits VLAN identifier (VLAN ID) according with 802.1q.
Switch cross-connections are based on Vlan Configuration Table where input and output ports or only out-put ports should be defined for any used VID. Vlan ID (VID) has a range from 1 to 4095.
Ethernet Flow Control (802.3x)
A network device asks its adjacent devices to send a pause frame because the input is faster it can process.The protocol used for this purpose is the flow control (802.3x).
Port Based Vlan
Port Based Vlan (or Lan per Port) allows to share the ethernet traffic (ingress or egress) in the interfaceSIAE switch.
7.1.5 Synchronisation unit (SETS)
Into ALFOplus80 a synchronisation circuit, SETS (Synchronous Equipment Timing Source), gets the syn-chronisation signal from the following different sources:
• LAN1
• LAN2
• radio
• Internal source
From the synchronization sources the reference clock is chosen on the base of alarm roots (Synch Loss,Synch Drift, Holdover, Freerunning), on the base of assigned priority, manual forcing and preferentialswitch (see Fig.13).
MN.00288.E - 004 33
The selected clock drives an oscillator through a PLL circuit. The oscillator will generate the required syn-chronisation for the frame generation. If no input signals are available the internal oscillator source is usedfor the local restart.
Fig.13 - Synchronisation block diagram
7.1.6 Bandwidth & modulation
ALFOplus80 radio family uses fixed Modulation (4QAM). It operates in an RF channel with the followingbandwidth:
• 750 MHz
• 1 GHz
7.1.7 ATPC interaction
The Automatic Transmission Power Control (ATPC) regulates the RF output power of the local transmitterdepending on the value of the RF level at the remote terminal. This value has to be preset from the localterminal as threshold high and low. The difference between the two thresholds must be equal or higherthan 3 dB.
As soon as the received level crosses the preset threshold level low due to the increase of the hop atten-uation, a microprocessor (µP), embedded in the ALFOplus80, at the receiver side of the remote terminalsends back to the local terminal a control to increase the transmitted power (see Fig.14).

7.3 RATE LIMITING AND INGRESS FILTER POLICING
7.3.1 Rate limiting
In SIAE equipment it is possible to apply the Rate Limit, i.e. to limit the total rate passing through an in-terface. It is possible to apply the rate limiting from 64 kbit/s up to the maximum port speed (up to 1GE).
The values that can be inserted are pre-fixed from 64 kbit up to 10Mbit (64Kb, 128kb, 256kb, 512kb, 1Mb,2Mb, 3Mb, 4Mb, 5Mb, 6Mb, 7Mb, 8Mb and 9Mb), In the range from 10Mbit/s up to 1Gbit/s the limiting val-ues can be chosen by the user with a 10Mbit/s step. i.e. the minimum selectable granularity is 10Mb/s.
7.4 ETHERNET PERFORMANCE MONITORING - RMON
RMON (Remote Monitoring) is a standard whose function is providing a set of services of statistics count,monitoring and alarm report with reference to the activity of a LAN network.
SIAE equipment support RMONv1, first MIB, as defined in RFC2819. This MIB contains real-time LAN sta-tistics e.g. utilization, collisions and CRC errors. These counters are managed locally into the radio equip-ment and are defined independently for each port of the device (both LAN and Radio interfaces). SIAE NMSsystems collect periodically this data and store it into the network database.
More in details, the RMON implementation in SIAE Network Elements is classified into two groups:
• RMON – Statistics: These are the counters data collected in real time by the Network Equipment.These data are stored in the network equipment itself and, the NMS Statistics viewer can visualizethis data with the “Refresh” button.
• RMON - History: This is managed by the NMS through the collection of the counters data from theNetwork Equipment. After a periodical polling to the Network Element, the NMS collects all the dataand these data are seen as the RMON History.
In other words, the “RMON Statistics” are the data that are collected and stored in the Network Equipment,while the “RMON History” is an aggregation of the data collected from each network equipment and thedatabase is located in the NMS.
7.5 RMON COUNTERS
RMON statistics are composed by counters for each port of the device that are stored in the equipmentdeployed on field.
Into the equipment it can be chosen to store the values with a sampling period that can be defined betweentwo values: 1 min, 15 min, or both. For each sampling period the counters values are stored into the equip-ment. After a predefined period (polling period), all the RMON data stored by the equipment are get by theNMS. The polling period can be either less than 4 hours (if the sampling period is 1 min) or 1 day (in casethe sampling period is 15 min). The NMS aggregates the files received to create a bigger database withthe History of the Performance Monitoring samples.
Here below are described the RMON counters available for each device interface (both LAN and radioports):
• DropEvents: Total number of events (frames, or whole queue contents) in which packets weredropped by the interface due to lack of resources.
36 MN.00288.E - 004
• Octets RX: Total number of octets of data (including those in bad packets) received by the interface.
• Pkts RX: Total number of packets (including bad packets, broadcast packets, and multicast packets)received.
• BroadcastPkts RX: Total number of good packets received that were directed to the broadcast ad-dress.
• Multicast Pkts RX: Total number of good packets received that were directed to a multicast address.
• CRC Align Errors: Total number of packets received that had a length between 64 and the Max Pack-et Size configured on the equipment switch (in any case not exceeding 10240 bytes) with bad FrameCheck Sequence (FCS) and an integral number of octets (FCS Error) or a bad FCS with a non-inte-gral number of octets (Alignment Error).
• Undersize Pkts: Total number of packets received that were less than 64 octets long and were oth-erwise well formed.
• Oversize Pkts: The number of packets received during this sampling interval that were longer thanmaximum allowable length (excluding framing bits but including FCS octets) but were otherwisewell formed.
• Fragments: Total number of packets received that were less than 64 octets in length and had eithera bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS witha nonintegral number of octets (Alignment Error).
• Jabbers: Total number of packets received that were longer than n (parameter Max Packet Size, itcan be set to 1522, 2048 bytes or 10240 Kbytes) octets, and had either a bad Frame Check Se-quence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a nonintegral numberof octets (Alignment Error).
• Collisions: The best estimate of the total number of collisions on this EthLannet segment.
• Utilization Rx: The best estimate of the mean physical layer network utilization on this interface dur-ing this sampling interval, in hundredths of a percent. The percentage is always referred to a 1Gbit/s port speed. So, it represents the mean RX throughput measured on the port during the samplingperiod and it is expressed as a percentage of a port speed.
• Octets TX: Total number of octets of data (including those in bad packets) transmitted.
• Pkts TX: Total number of packets transmitted.
• BroadcastPkts TX: Total number of good packets transmitted that were directed to the broadcastaddress.
• Multicast Pkts TX: Total number of good packets transmitted that were directed to a multicast ad-dress.
• Utilization TX: The best estimate of the mean physical layer network utilization on this interface dur-ing this sampling interval, in hundredths of a percent. The percentage is always referred to a 1Gbit/s port speed. So, it represents the mean TX throughput measured on the port during the samplingperiod and it is expressed as a percentage of a port speed.
All the counters described above are part of the RMON statistics and it is not possible to collect only a sub-set of them. It is however possible to select on which equipment interface activate the RMON statistics (forexample, they can be enabled only on the radio interface). This allows reducing the total amount of PMdata, for example avoiding data collection from unused LAN interfaces. This can be done on all PayloadInterfaces (regardless if electrical or optical), the Radio interfaces are included as well.
7.6 ADVANCED STATISTIC MONITORING FOR SERVICES AND PRI-ORITY COUNTERS
In addition to the Ethernet Counters per Port with SIAE equipment it is possible to set on the Radio interfacethe RMON counters per Service (Vlan) or Priority (Queues). Differently from the previous RMON counters,the Service and Priority counters can be activated for the following variables.
• Octets TX: Total number of octets of data (including those in bad packets) transmitted.
MN.00288.E - 004 37
• Pkts TX: Total number of packets transmitted.
• Octets RX: Total number of octets of data (including those in bad packets) received by the interface.
• Pkts RX: Total number of packets (including bad packets, broadcast packets, and multicast packets)received.
• DropEvents: Total number of events (frames) in which packets were dropped by the interface dueto lack of resources.
The Service and Priority RMON can be activated and collected from NMS (Network Management System).The Service and Priority RMON are based on the Advanced Ethernet Counters present on the equipmentand configurable on site. This means that on site it is possible to activate the Advanced Ethernet Countersbut not the Service and Priority RMON.
In any case the NMS has higher priority in respect to the configuration inserted through Web LCT. Thismeans that the local operator can enable and read the active measure, but when the configuration of theseRMON is done through NMS, the local operator can only read the values of the Advanced Ethernet Counters.It is not possible to enable the RMON for Priority and, in the same equipment, the RMON per Vlan.
7.6.1 Priority RMON
The Priority RMON are based on the internal Queue of the equipment, not on the value of the Priority; thisimplies that:
• the maximum number of RMON (Priority) that can be enabled are limited to 8, i.e. the number ofthe queues available in SIAE equipment.
• if traffic with different priorities are listed in the same Queue, the Priority RMON will work with oneProbe on the Queue. I.e. the traffic in the same Queue is seen as “Same Priority Traffic” and thePriority RMON counts the frames belonging to the Queue
In other words, with Priority RMON there is a probe for each queue (8 queues in SIAE switch). Each probecounts the variables listed above (Octets TX, Pkts TX, Octets RX, Pkts RX and DropEvents).
These counters will be available only with the Minimum Polling Policy of 15 min.
7.6.2 Service RMON
The Service RMON counters allow the equipment to track the variables listed above depending on the Ser-vice (Vlan Tag). This type of RMON can be set only on the Radio interface.
Each equipment can be set to collect RMON up to 32 Services (Vlan Tag) and only on Customer Tag.
These counters will be available only with the Minimum Polling Policy of 15 min.
7.7 SYNCHRONISM
Network Synchronisation is a growing subject related to the network evolution from TDM to Ethernet pay-load.
In this chapter it will be described the different features supported by SIAE switch equipment for the syn-chronization transport. The decision of the correct source to enable and how to pass the synchronisationsignal to customer’s equipment depends on network situation which has to be evaluated case by case.
38 MN.00288.E - 004
Fig.16 - NodeB and BTS synch
The main concept is to transfer the synchronization signal throughout the network deployed. This impliesthat SIAE equipment will take the clock signal from the concentration points (POC) and transfer it towardsthe tail sites and distribute the synchronization signal to the external equipment such as NodeBs and BTS(see Fig.16).
Fig.17 - SETS circuit
Going into details, this means that each SIAE equipment (represented in Fig.17) will have, at least, one“Input” and one “Output” CK.
Input (CK IN) is/are the interface/s where the SIAE equipment get the Clock signal from, these could beanother SIAE equipment or external equipment.
Output (CK OUT) is/are the interface/s where the SIAE equipment provides the Clock Signal to, these couldbe another SIAE equipment or external equipment.
Internally to each SIAE equipment the SETS identify the input and output types of interfaces by the fol-lowing codes:
• TE: This code represents an Ethernet interface (LAN) used as input CK
• T0: Output interface. This code represents the Internal Clock
The purpose of the above list is to list the different acronyms used by the SETS that may be present in theconfiguration screens.
When the Synchronization is enabled in SIAE MW equipment, in the configuration screen, there are somefeatures to be used for maintenance or refined tuning of the clock propagation.

Fig.18 - Synchronisation menu
Here below are listed the different configurations to be made:
• Status Control: this is a forced status for maintenance purposes of the SETS. It can be forced in
- “Free Running”: Independently from the synchronization signal received, the clock is locked ontothe internal clock.
- “Hold Over”: The SETS is locked into the internal clock which tries to preserve the frequencyreceived when the SETS was locked.
- “Locked”: in this case the SETS is locked to a source of synchronization.
• “Time” Settings: these are general setting for the synchronization
- “Hold Off Time”: Time (expressed in ms) during which the system keeps the evaluated frequen-cy of a synchronism source become invalid (not present or degraded). At the end of the HoldOff time, the invalid source will be rejected and the first input source having a valid signal willbe used.
- “WTR Time”: i.e. Wait-To-Restore, this is a wait time to avoid oscillations. Time (expressed inminutes) that has to pass before allowing the selected valid input source to be actually usedwithin the process for the selection of T0 synchronism.
• “LTI Set Time” and “LTI Reset Time”: are controls that avoid oscillations of Alarms. When one alarmraises up, it has to be active for at least the “LTI Set Time” and when it disappears it has to be offfor at least “LTI Reset Time”.
7.8 SOURCES OF SYNCHRONISM
SIAE equipment is able to select among different sources of synchronization. A priority has to be assignedto enable each source, with a value ranging from 1 to 9 included. The priority 1 corresponds to the maxi-mum value, while the priority 9 corresponds to the minimum value. The priority shall be used to select inwhich order the different synch sources must be used. In case the Priority is set as “Disabled” the corre-spondent interface is not used as a synchronization source.
40 MN.00288.E - 004
Fig.19 - Source of synchronisation
The selectable sources of synchronisation are listed below. For each source it is also listed in square brack-ets the correspondent acronym used by the SETS:
• Radio Interface: depending on the RF configuration it is possible to have 1 radio interfaces (1+0).
• GE Interface [TE]: to identify which LANs are the sources of synchronization they have to be chosenunder “TE LAN A” and “TE LAN B”. This implies that a maximum of 2 LAN interfaces can be set assource of synchronization. The AGS-H reference clock can be received on any one the 4 LAN inter-faces, independently from the fact they are electrical or optical. In order to receive the synchroni-zation signal (and regardless of the SSM status) the GE interface has to be set as “Slave”. Theconfiguration choices and other details are explained in “SSM on Ethernet Interfaces”.
• Internal Clock [T0]: with the Synchronization not enabled the equipment is locked into its internalclock
In case SSM is not enabled, the equipment switches from one source of synchronization to another follow-ing the priority scale, starting from the source set to priority 1 and scaling to the sources with higher valuesof priority (i.e. lower priority level). The synch source switch occurs when the present source suffers oneof the following events:
• The source of synchronization is not physically available
• The clock deviation is bigger than 4.6 ppm (maximum deviation that the internal clock can follow).
In other words, if the LAN1 is selected as first source (priority 1) of synchronization, and the LAN2 is se-lected as the second source (priority 2) of synchronization, the SIAE equipment will be synchronized onthe LAN1 until the cable will be physically unplugged or the LAN1 frequency and phase will be out of theirspecified ranges. Once one of these events occurs, the SIAE equipment will switch the source of synchro-nization to the second source listed. If the second source listed is unplugged or out of maximum range thenthe SIAE equipment will switch to the third source and so on.
In case no other synch sources are available the SIAE equipment will go on “Internal Source”, i.e. the in-ternal clock present in SIAE equipment. In this condition the internal clock will be kept in hold status, tryingto keep the last synchronization reference received. In these conditions, the internal clock of SIAE equip-ment has a reliability of 0.3 ppm over 24 h. When the SIAE equipment switches to internal clock, it prop-agates a quality of SEC – SDH Equipment Clock.
MN.00288.E - 004 41
7.9 PROVIDE SYNCHRONISM TO EXTERNAL EQUIPMENT
Once the SIAE equipment is synchronized, the clock signal has to be passed toward external equipment orother SIAE equipment. SIAE equipment can give the synchronization signal through different interfaces.
Fig.20 - Provide synchronism
The interfaces that are available to provide synchronization to other SIAE or external equipment are:
• Radio: this interface is passing the synchronism automatically to the remote equipment. No config-uration is needed.
• GE Interfaces: the TX CK of the all GE lines (i.e. LAN 1 and 2) is locked to the SETS. In this way,the CK can be passed through these connections to other equipment provided that they supportSynchronous Ethernet. The GE Interfaces when used in Electrical can provide the CK signal to otherequipment: in this case the equipment port role must be “Master”. Once the synchronization is en-abled in the SIAE equipment, automatically all the LAN interfaces are locked onto the SETS. Thisimplies that the synchronization signal is automatically provided onto all the LAN interfaces
The choices of the interface to pass the clock signal depend strictly on the external equipment. This meansthat in first place it is necessary to establish the possible sources of synchronization available on the ex-ternal equipment. Depending on the availability of these sources, SIAE equipment will be configured withthe correspondent interface to pass the clock signal.
7.10 G.8264 SSM – SYNCHRONISATION STATUS MESSAGE
The SSM is a protocol that transmits the quality of the synchronization message throughout the network(G.781).
In the synchronization network the transmission of the quality of the clock allows the network to be scal-able and to provide redundancy. In case of failure of SIAE equipment or cable, it is helpful to provide re-dundancy for clock propagation in order to avoid synchronization loops.
Synchronisation loops could happen after a failure when two equipment are synchronising each other onthe same physical connection. If this happens the equipment will not present any alarm on the synchroni-zation but will generate and propagate a not reliable clock.
The quality of the clocks that are propagated are:
• PRC: Primary reference Clock – Best quality clock reachable (Cesium Clock)
42 MN.00288.E - 004
• SSUT: Synchronization Supply Unit Transit (Rubidium Clock)
• SSUL: Synchronization Supply Unit Local
• SEC: SDH Equipment Clock ( Cristal Clock)
• DNU: Do not Use – This signal informs the receiver to do not use this clock
Here above are listed in order from the better quality clock (PRC – Primary Reference Clock) to the worsequality clock (DNU – Do Not Use). The better the quality is the more time can the SIAE equipment stay inholdover (Internal Clock) without a degradation of the payload. In other words, better is the quality, longercan remain reliable the clock in holdover cases.
The DNU quality is always propagated on the source on which the equipment is locked for synchronization.In this way the Loops of synchronization are easily avoided.
Unless the user forces the CK quality input/output, SIAE equipment reads the quality present in the inputinterfaces. This means that, unless there is some user’s modifications, SIAE equipment propagates thequality of the clock as it is. I.e. the output quality is the same as the input quality.
E.g.: If in the input interface (POC Site) there is a quality of SSUT of the CK signal, SIAE equipment willpass throughout the network this synchronization signal with a quality message of SSUT.
In case the SIAE equipment is in Holdover (internal clock) it changes the quality of the synchronization to“SEC” quality. With SSM enabled, SIAE equipment will choose the sources of the synchronization based onthe better quality received.
In general, the equipment selects the synch source with the following criteria:
• it chooses the sources with the highest quality
• if more than one source have the same quality, the one with the highest priority is selected (i.e. theones that have the smaller priority value, from 1 up to 9)
• in any case, if a DNU quality is received on the highest priority source, this latter is discarded andthe equipment selects an alternative source.
Example 1: if one SIAE equipment has the two following sources of synchronization, with the same priority:
a. LAN1 with quality SEC (Priority 1)
b. Radio with quality SSUT (Priority 1)
In case the sources have the same priority, the SIAE equipment will switch the source of synchronizationto the best quality, in this case (b) the Radio with SSUT quality.
Example 2: if one SIAE equipment has the two following sources of synchronization, with the different qual-ity and different priority:
a. LAN1 with quality SEC (Priority 1)
b. Radio with quality SSUT (Priority 2)
In case the sources have different priority and quality, the SIAE equipment will switch the source of syn-chronization with higher quality, in this case (b) the Radio with Priority 2 and quality SSUT. However, if aDNU quality would be received on Radio, the SIAE equipment will switch the synch source to LAN1 inter-face.
Example 3: if one SIAE equipment has the two following sources of synchronization, with the same quality:
a. LAN1 with quality SSUT (Priority 1)
b. Radio with quality SSUT (Priority 2)
In case the sources have equal quality, the SIAE equipment will switch the source of synchronization withhigher priority, in this case (a) the LAN1 with Priority 1 and quality SSUT. However, if a DNU quality wouldbe received on LAN1, the SIAE equipment will switch the synch source to Radio port.
The quality of the synchronism has to be enabled for each SIAE equipment and can be transported on thefollowing interfaces:
• On the Ethernet Interfaces through a standard protocol (according to ITU-T G.8264)
• Radio interface with Local/Remote Telemetry: Depending on the MW link configuration (1+0) theSSM messages are passed to the remote SIAE equipment in different ways.
- 1+0 Configuration: In this case there is one Local/Remote Telemetry passing the SSM messages
MN.00288.E - 004 43
Within this configuration table there are also some maintenance configurations such as:
• Forced Switch: this command allows the operator to force the SETS to lock to a predeterminedsource. This command is above all other configurations. This means that the SETS will be lockedonto this source even if the cable is unplugged
• Preferential switch: In case two sources have equal priority it is possible to set a Preferential Source.In any case the quality is the main parameter of choice, then when two sources have the same pri-ority, the preferential source is chosen.
In relation to the SSM, it is possible to:
• Visualize the quality of the clock signal received and transmitted (Rx Quality and Tx Quality)
• Overwrite the Quality received or transmitted (Ovw Rx Qlty and Ovw Tx Quality) and the choicesare:
- PRC: Primary reference Clock – Best quality clock reachable (Cesium Clock)
- SSUT: Synchronization Supply Unit Transit (Rubidium Clock)
- SSUL: Synchronization Supply Unit Local
- SEC: SDH Equipment Clock ( Cristal Clock)
- DNU: Do not Use – This signal informs the receiver to do not use this clock
The Overwrite of the Quality of the Clock is configurable by the user and simply forces in input or outputthe quality. This can be useful in case the SSM is not supported by external equipment or in case the 2MHz signal is used to pass the synchronization. Moreover, if the SIAE equipment is set with SSM enabled,its SETS will choose a source of synchronization that has the quality available.
7.10.1 SSM on Ethernet Interfaces
In order to propagate the clock signal through the Ethernet 1GE Electrical interface it is necessary to setcorrectly the master and slave option for each interface. It is possible to assign the roles (Master or Slave)statically (as set up for source LAN) or dynamically (according to Synch direction).
This because the Master interface transmits the clock to the Slave interface and in case the direction ofpropagation of the clock has to be changed (line failure, insufficient quality, etc..), the master and slaveassignment has to be re-negotiated with a consequent loss of traffic. This re-negotiation implies an inter-ruption of the traffic from 2.4 to 2.6 seconds.
SIAE equipment allows to set the role of the interfaces to “According to synch direction” (dynamic), theflow of the propagation of the clock signal is automatically changed depending on the transferring directionof the CK. If the role of the interfaces is set to “As set up for source LAN” (Static), the flow of the propa-gation of the clock signal is fixed (see Fig.21).
Fig.21 - LAN synchronisation method
The other configuration present in SIAE equipment that manage the role of the LAN interfaces (Master/Slave) is present in the main configuration of each LAN interface. Regardless if each LAN interface is setmanually as Master/Slave or with autonegotiation, the setting of dynamic or static in the SSM configurationis privileged.
In other words if the Master/Slave are set manually in the interface configuration and in the SSM is set“According to synch direction”, if needed, the role of the LAN changes according to synch directions.
When an electrical GE interface is in Master State (despite from the fact that it comes from a “static” or“dynamic” setting) every synchronization signal that is coming from this interface has automatically the
44 MN.00288.E - 004
quality of DNU. This does not occur for optical GE or FE interfaces (Electrical and Optical), where the “Mas-ter” and “Slave” roles are not foreseen and so the transmitting direction for the clock can be exchangedwithout any port role re-negotiation. All the Ethernet interfaces are locked on the SETS, regardless whichLAN interfaces are set as sources of synchronization. Nevertheless the “Overwrite RX Quality” and “Over-write TX Quality” can be applied only on the LAN interfaces used as sources of synchronization.

8.2 GENERAL
The ALFOplus80 radio system is made up of an outdoor unit, protected by a metallic shield. Compliance toelectromagnetic compatibility is guaranteed through the following precautionary measures:
• during the design phase
- use of protection circuits against electrical dischargers
- use of filters on the power supply input circuits against noise propagating on the power supplywires
• during the installation phase
- use of shielded cables
- use of ground connections.
The installation phases of the whole system are described in the following paraghaphs and it must be doneonly by service person suitably trained.
Warning: Remember that the whole radio link can work only if ODUs chosen for local and remote side haveequal sub-band and different Tx module (H and L).
8.3 ELECTRICAL WIRING
The electrical wiring must be done using appropriate cables thus assuring the equipment responds to theelectromagnetic compatibility standards.
The cable terminates to flying connectors which have to be connected to the corresponding connectors onthe equipment front.
Position and pin-out of the equipment connectors are available in this section.
8.4 CONNECTIONS TO THE SUPPLY MAINS
During the final installation, protect the ODU by a magneto-thermal switch (not supplied with the equip-ment), whose characteristics must comply with the laws in force in one’s country.
The disconnection from the supply mains is made disconnecting the auxiliary connector M12 5Pin from theODU or disconnecting the LAN PoE cable.
The typical magneto thermal switch has characteristics at least 48 Vdc @1.5A with overcurrent relay class“C” or “K” tripping curve.
Seal the auxiliary power connector when the radio is powered via PoE, in order to avoid the removal of thecover without tools.

9.6 OPTIMIZING ANTENNA ALIGNMENT WITH RX MEASUREMENT
When the whole radio link is on, antenna alignment can be optimised. Antenna alignment optimization isperformed depending on the Rx signal power at local and remote equipment and evaluating both local andremote S/N value maximizing them. There are two possibilities to see the Rx signal power level:
• through WebLCT interface
• through a voltmeter connected to auxiliary connector on the ODU (F03608 cable - see Fig.58).
In order to get the Rx signal power level via software, connect the PC to ALFOplus80 (LAN2) and start thecommunication towards the ODU microcontroller with SCT/WebLCT supervisory program.
Into WebLCT is shown in the top status bar (Rx1A= -value dBm) see Fig.80:
If you’re using a voltmeter the Rx signal power level is available on the auxiliary connector of ODU, themeasurement can be performed with a proper cable (see Fig.58). Following this last procedure, the voltageyou’re reading with the voltmeter is proportional to Rx power level, refer to Tab.23.
Tab.23 - Voltage measured in auxiliary port
Received Signal (dBm) Signal Output (V) Error (dB)
-20 4.68 ±5
-30 3.51 ±5
-40 2.34 ±3
-50 1.17 ±3
-60 0 ±3
-70 -1.17 ±3
96 MN.00288.E - 004
Typical Rx signal power level -40 dBm. It is the most important item to optimise the antenna alignment,but in a situation of interference Rx level can be good, BER acceptable but S/N margin low. This meansthat when Rx fields will decrease then BER will increase fast. The situation can be easily shown with SCT/WebLCT software looking at Signal Quality level. Into WebLCT Software select:
• Equipment menu
• Maintenance
• S/N Meas. card (see Fig.81)
The S/N at nominal Rx level, read by WebLCT, must be 18dB@ 4QAM (typical S/N: 20-22dB) (see Fig.81).
Fig.81 - S/N measurement monitoring
Antenna aiming
Optimise antenna aiming towards remote side, operating on the “azimuth” nuts (1) and the “elevation”nuts (2) to maximize antenna strength signal (see Fig.82 and Fig.83).
- fine azimuth adjustment ± 7° (see Fig.83)
- fine elevation adjustment ± 30° (see Fig.82)

9.7 ODU ACCESSING AND REMOTE MANAGEMENT
Local ALFOplus80 ODU and its remote ODU can be accessed via LAN2 or LAN1 ports depending on super-visioning parameters, once the radio link has been initialized correctly (Local&Remote). In SCT the window(see Fig.84) shows the network element belonging to selected station. In the “login” column you can checkthe actual user profile of equipment (SYSTEM=Administrator; MONITOR=Read only) and which is the localradio (local) and remote radio (remote link). To change the user profile, select the network element andpress Login.
To connect in remote radio you can press double click on remote link element or select Remote Link -equipment - LCT interface.
In WebLCT software press Open Far End button to open and manage the remote radio window.
If the remote link is not visible, it means that the remote element list is missing in the local ODU (in SCT- Tools - Subnetwork Configuration Wizard).

10 ALFOPLUS80 ALARMS AND LOOPS
10.1 GENERAL
A radio link generating alarm requires troubleshooting.
The troubleshooting of the ALFOplus80 can be organized on the basis of alarms.
Basic alarms come from LEDs on the equipment and all the active alarms can be observed through SCT/WebLCT.
In this document is present ALFOplus80 alarm list and a description of the loop facilities provided into theequipment.
10.2 ALARMS
Alarms can be pointed out through unit LEDs and/or through SCT/WebLCT software.
10.2.1 Alarm indications
There are two ways of processing the alarms:
• through LEDs
• through SCT/WebLCT
Alarm associated to ALFOplus80 can be classified in different groups. Names and composition of thesegroups as well as association between alarm classes and relay contact can be defined by the customer.
106 MN.00288.E - 004
Alarms are divided into 4 severity levels according to the effects that an alarm might cause to the regularoperation of the unit detecting it. Levels are prioritised as follows:
• Critical (red): out-of-service, hw failure, urgent alarm
• Major (orange): loss of signal, minimum residual functionality, urgent alarm
• minor (yellow): failure neither urgent, high residual functionality, not urgent alarm
• warning (light blue): indication or wrong configuration, not urgent alarm
• none (green): no alarm or masked alarm.
Critical and Major alarms indicate impossibility of executing a service, hence the faulty units needs to beserviced. Minor level represents the not urgent alarms which do not prejudice service continuity. Warninglevel indicates malfunctions that might be locally removed without having to replace the unit.
Alarm classification can be modified via SCT/WebLCT operator. A short description is given for each alarmin “Alarms” section with relevant class.
The visual indication is given by a LED, which can be green or orange or red. The information provided are:
• Red light:
- ON - An internal alarm is active. Connect the PC for troubleshooting
- Flashing - An external alarm is active
• Green light
- Flashing - No radio connection with far-end terminal
- ON - Radio connection with far-end terminal is active
• Orange light: during restart

11 ALFOPLUS80 MAINTENANCE AND TROUBLE-SHOOTING
11.1 GENERAL
In the following pages are listed all the procedures to follow for ALFOplus80 maintenance.
When corrective maintenance is necessary, a troubleshooting procedure helps the operator to identify thefailure unit to replace it with a spare one.
11.2 MAINTENANCE
Maintenance consists of two stages:
1. periodical checks to be carried out using SCT/WebLCT
2. corrective maintenance.
Periodical checks serve to detect correct radio performance without the presence of any alarm condition.
Corrective maintenance takes place as soon as one or more alarm conditions are in existence. Operationsequence to be carried out is shown in “Troubleshooting” paragraph.
11.2.1 Periodical checks
System routine maintenance consists in a series of routine checks aiming to verify correct operating modeof an alarm–free system.
These checks are made through SCT/WebLCT program, installed on a PC.
The items to be checked are:
• Tx power (i.e., attenuation value in dB vs. nominal value)
• Rx field (value measured must comply with that resulting from hop calculation)
• S/N (presence of possible interference)
• BER (values measured must comply with hop calculations)
How these operations are carried out is specified in “Line–up” section or, more widely, in ALFOplus80 soft-ware manual.
110 MN.00288.E - 004
11.2.2 Corrective maintenance (troubleshooting)
Corrective maintenance starts as soon as one or more alarm indication become active.
Corrective maintenance purpose is to locate the faulty unit and replace it with spare after having verifiedthat the cause of faulty is not external to the equipment.
Corrective maintenance does not include malfunction due to a wrong or incomplete configuration of thesystem or to failure due to alarm indication system itself or any other cause external to the system, i.e.:cabling damage, main voltage loss, antenna misalignment and propagation problems.
See paragraph 11.3 TROUBLESHOOTING for details.
11.3 TROUBLESHOOTING
Main purpose of troubleshooting is to identify the possible cause of alarm:
• Propagations of microwave
- interference (in a link radio turn off the Ptx module (local & remote)and monitoring the Prx dur-ing the day, active local Link ID)
- desalign of antenna (check positions and screws, maximize the voltage AUX connector presentin ODU)
- obstacle in the 1° Fresnel Zone (tree, tower building, etc....)
- using the “Performance Monitoring” Prx, Ptx BER measuring
- particular condition (heavy rain, stratification of different air temperature, flat surface)
• Radio hardware faulty
- alarms due of a wrong configurations or actual status of the radio
- faulty (using embedded radio BER test generator and loops, to check hardware failure)
• External event
- no constant 48 Volt power supply during the day/night
- very high temperature, humidity inside waveguide
- ODU operating range -33°C to +55°C; survival temperature range -40°C to +60°C
- ODU waterproof according to IP65 environmental class
The troubleshooting procedure is performed with:
• check value of Power Transmitter and Receiver
• reading Current Alarms and Alarm History labels and trying to figure out which part of the equip-ment is affected.
• disabled All Manual Operations
• verifying with radio BER test a hardware failure or S/N measure
• verifying the correct initialization of the Local and Remote Radio
• HW restart
• factory default
• firmware update
• replace with a spare part.

Section 6.PROGRAMMING AND SUPERVISION
12 PROGRAMMING AND SUPERVISION
12.1 GENERAL
ALFOplus80 is programmed and supervised using SCT or WLC. This subject is fully described in the sepa-rated software manual (Web LCT ALFOplus80 - Software application for the management of ALFOplus80equipment).
Warning: Operating system compatibility for SCT and WLC are Windows XP or Windows7.
12.2 SUPERVISION THROUGH ETHERNET
The provided structure for Ethernet traffic defines the management facilities of "ALFOplus80" unit.
112 MN.00288.E - 004
Fig.88 - Traffic management of "ALFOplus80" unit
12.2.1 General
In general the management plane can be configured to be managed “in band”, that is transported withdata and differentiated on the base of VLan, or “out of band”, where a port is exclusively dedicated to themanagement. In particular, for management purposed, the LAN interfaces can be configured as follow:
• Disable - the management is not transported for that LAN
• Local Access Only - LAN is dedicated to the management and it allows to reach the local CPU only
• In Band - LAN is configured to transport both management and data: management is differentiatedby dedicated VLan
• Out Of Band (OOB) - LAN is dedicated to the management and the management forwarded overthe radio is maintained segregated from the data (in this application the segregation is virtuallyachieved via LAN)
• Drop Node - LAN is dedicated to the management and it is possible to access to both local CPU andthe rest of the network.
The combinations of management configuration for LAN1 and LAN2 are shown in the following.
Disable - Local Access Only (LAO)
LAN1: Disable LAN1 is for data only
LAN2: LAO LAN2 is local management only

12.2.2 Configurability
The management mode of equipment affects the Ethernet Channel and on the Switch configuration (RSTP,OAM, …). Therefore it is important to decide the optimal configuration of traffic Ethernet and management,to avoid blocking traffic conditions.
In Out od Band a dedicated service channel for management does not exist, but this is forwarded to radioside using “internal Vlan stacking” with priority 7, so that traffic IP with priority 7 (802.1p) could affect thespeed of management traffic.
The disabling of port A interface can cause outage of management and IP traffic.
12.2.3 Address
The unit uses a single IP address associated at the management port of controller and a single "defaultgateway".
12.2.4 Restore supervisioning access mode
The “RESTORE OF CPU ACCESS” command is available through serial port (F03594 cable) via Hypertermi-nal (115200bps,n,8,1):
• Login SYSTEM
• Password SIAEMICR
• Type string: lao
This string restores the factory default of port configuration:
• LAN1 disable
• LAN2 local access only
