2FIRSTAIDFORELECTRICAL 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 line
switches. 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 procedure
for 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 while
artificial 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.00356.E - 003 9
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.

5 SYSTEM PRESENTATION
5.1 GENERAL
This document contains the description of features and capability of ALFOplus2 equipment.
ALFOplus2 (see Fig.5) is a Full Outdoor microwave radio that houses, within a unique unit, two complete
TX/RX radio channels (RF Multi-core definition) to double the radio capacity and includes a complete Carrier
Ethernet features set. With 4096QAM Modulators, Ethernet Header compression, MIMO ready architecture
and 2x112MHz canalization capability, ALFOplus2 set the new standard in point to point Microwave sys-
tems.
The ALFOplus2 must be used in RAL areas (Restricted Access Location) where an equipotent bonding has
been applied. The ODU unit has a supplementary specific connector for a permanent connection to ground-
ing point intended to be installed by technical staff only.
Fig.5 - ALFOplus2
5.2 CHARACTERISTICS
This document contains the description of features and capability of ALFOplus2 equipment.
Dual Carrier ALFOplus2 is the first SIAE MICROELETTRONICA point to point microwave device capable of
providing, in a unique solution, highest modulation schemes and software defined architecture in a highly
integrated design.
ALFOplus2 flexibility makes it suitable perfectly to all the last generation network requirements fitting per-
fectly in Macrocell Backhaul, C-RAN CPRI transport, Macro-site Aggregations scenarios.
16 MN.00356.E - 003
5.3 APPLICATIONS
ALFOplus2 is the ideal solution in urban environments for all carrier-class applications in which the typical
requirements are Ethernet connections:
• full IP radio, providing the foundation for a leading edge network
• fully integrable with 3G, 4G, LTE nodes and backhaul
• ideal for a fast and flexible evolution towards full IP network
• complementary solutions for fiber deploy
• last mile fiber extension for business customers
• ISP high capacity and performance, for LAN-to-LAN connections
• emergency wireless links
• zero footprint applications
ALFOplus2 doesn’t need any indoor unit and the power supply can be provided directly by POE through the
data cable or through a dedicated auxiliary port.
5.3.1 ALFOplus2 connectivity
ALFOplus2 offers 4xGbE traffic ports (see Fig.6):
• 2xGbE Electrical ports (1Gbps line rate): LAN3 and LAN4 (with PoE)
• 2xGbE Optical interfaces (1Gbps or 2.5Gbps line rate): LAN1 and LAN2.
Interconnection ports are present for communication between two ALFOplus2 when 2+2/4+0 configura-
tions are implemented.
Auxiliary connectors are in place for Direct Power supply feeder, Local Access and RSSI indication.
In case of protected configurations one traffic port is used as signaling interconnection interface.

5.3.2 Universal product line architecture and single SM-OS
The increased number of application segments demands for a spread of microwave technologies in order
to address each of the segments in an effective and efficient way.
This scenario brings to a higher complexity in microwave portfolio challenging for the consistency of the
overall network solution and streamlined roadmap.
MN.00356.E - 003 17
SIAE MICROELETTRONICA answer is based on the adoption Unified Product Architecture, a common Ether-
net hardware and software platform through all new generation products based on two main building
blocks:
• Ethernet Core unit based on powerful switching gear featuring 46Gbps switch fabric capacity, high
performance dual-core CPU and embedded IEEE1588v2 processor for advanced synchronization ca-
pability.
• SM-OS software, based on carrier-grade field proven highly interoperable protocol stack provides
complete MPLS services set and compliancy to CE2.0.
ALFOplus2 has been developed with this concept in mind: Unified Hardware and Software platform archi-
tecture
5.4 ALFOPLUS2 STRUCTURE
ALFOplus2 mechanical structure is made up by a main body and three possible additional antenna-interface
modules, lodged in the reserved bay (see Fig.7).
The main body is common to all applications an presents 2 antenna ports.
Fig.7 - Composition of ALFOplus2 and interface modules
The antenna-interface module is specialized in accordance with the required application (see Fig.8):
• OMT module: it contains an OMT element that combines the two antenna ports of the main body in
a unique antenna port for H/V integrated operations (Antenna Flange is circular)
• HYB module: it contains a HYB element that combines the two antenna ports of the main body to a
unique antenna port for frequency diversity operations (Antenna Flange is circular)
• PASSTHROUGHT module: it exposes both antenna ports (Antenna Flanges are rectangular).
5.5 LINK CONFIGURATION
Radio link configurations: single and dual equipment operation is possible.
3 kind of antenna interface modules
can be lodged in the main body bay
Main body bay lodges one of 3
antenna interface modules:
OMT,Pass-through or Hybrid
OMT PASS-THROUGHT HYBRID
