First aid: artificial breathing(mouth to mouth)

1

In case of electric shock you have to ensure the first aids to

the patient, but to do this you have to consider two very

important things:

- interrupt immediately the electric circuit;

- if the circuit has not been interrupted, do not touch

the patient with bare hands;

After doing this, without delay contact the nearest mobile

unit of first aid and practice to the patient, in case of loss of

consciousness, the breathing mouth to mouth as described

below.

2

Put the patient lying on his back with the arms parallel to

the body, ensure that he does not have the breathing tracts

obstructed (chewing-gum, dental prosthesis, etc.),

otherwise set him free from foreign bodies.

Kneel near the patient’s head and putting a hand under his

neck, incline as possible his/her head backwards.

3

Going on with keeping the patient’s head inclined with one

hand, use the other one to occlude the nostrils, if you are

going to practise the breathing through the oral cavity, or

occlude the mouth if you want to do it through the nasal

cavity.

While doing this begin the auto-oxygenation, with deep

breathing.

Then practice the artificial breathing blowing in the chosen

cavity beginning with ten expirations each minute to go on

them with twelve and fifteen.

4

During the breathing procedure you have to control that the

patient’s chest dilates, otherwise change cavity where to

blow the air because the previous one could be obstructed.

5 Do not ever stop the artificial breathing until the patient

has recovered or the first aid unit has come.

1. GENERAL DESCRIPTION The EK-UNM/3 board is the interface between Base Band steams and radio link. For the

Mo/Demodulation part it’s possible to use OFDM and Single Carrier mode, the mode can be

different for each direction Transmission/Reception.

1.1 MODEM

Modulation parameters of the Single Carrier modem can be set by front panel, Eurotek MST (Local

Craft Terminal) and SNMP. The microprocessor on the board computes all the required coefficients,

in order to optimize performances, basing on parameters chosen by user (if incoherent parameters are

chosen an alarm occurs). The transmission and reception parameters can be different from each other

(example: Tx: 32QAM 9/10 Rx: QSPK 7/8). When Single Carrier modem works in QPSK mode, the

modem is perfectly DVB-S EN 300 421 v.1.1.2 compliant. If other constellations are chosen the

format is Eurotek proprietary.

When the modem works in OFDM mode is compliant to the standard DVB-T EN 300 744 v.1.5.1,

only 2k mode is supported.

1.2 SCRAMBLER

In order to make the signal unintelligible by others, it is possible to use a Eurotek proprietary

scrambler with a 16 bit key.

1.3 MPA

The MPA unit works as transparent Multiplexer. The five inputs are connected to the signals coming

from:

ASI In 1

ASI In 2

INT In 1

INT In 2

GbE

The transport stream present on a particular input can be mapped to one of the eight Virtual Channels

(VC1 – VC8) of the VC mapper. If an input is not used it can be connected by the menu to the Waste

container. After the mapping procedure between the input transport streams and the desired Virtual

Channels, an unique transport stream is generated with the Data Pid assigned by the menu.

Multiplexing process of MPA generates an overhead, its entity it is visible in the next formula:

Out Bit Rate >{ 188/183 * [Σ Input bit Rate] + 40 kbit/sec } +5%

It is possible to set the bandwidth limit of each single input, in this way the overload of one input

does not affect other inputs behavior. When the sum of bandwidth limits exceeds the maximum

capacity of the modulator, an alarm occurs.

8 EK-UNM/3

31/10/2012 Arch. 3828 601-000160/MN Rev. D

1.4 DMA

The DMA allows to carry out a single transport stream from a multiplexed transport stream. The

packet selector module filters out all the packets except those with the selected DATA PID. The

transport stream is then sent to the VC demapper in order to extract the selected virtual channel

towards the output.

1.5 GBE

The transport of Ethernet packets is managed by GbE unit, that maps the Ethernet packets in a

HDLC/VCAT stream encapsulated in a TS, the encapsulation process allows the transport of IEEE

802.1Q packets. The overhead of encapsulation calculated for Ethernet packets of minimum length

(53 byte) is reported in the next formula:

overhead GbE = 188/183 * 530/529 * 70/64 = 1.1258…

Inverted operation is done on the other direction.

The bitrate is configurable by menu, so it is obvious that the bitrate does not change respect to the

data on the Ethernet network and does not produce unwanted disservices. A DDR memory manage

the requested buffering.

1.6 PORTS

It is possible a wide selection of connections between ports of front panel and internal modules, this

feature allows the adaptation to complex network structures.

Over the routing capacity in base band, this board allows to bring on the IF output the IF signal

coming from another modulator and to adjust the output power level.

It is possible to connect to the demodulator both the IF internal connection and the IF signal coming

from IF2 In port (for example to use the signal coming from another radio link).

If only demodulator part is used, it is possible feed the modulator with the demodulated signal to

avoid undesired alarm on modulator part, vice versa it is possible to feed the demodulator internally

with the IF signal of the modulator to avoid alarm on demodulator part.

possible to select which virtual channel can be carry out.


On the INT 1 VC Pass variable we set 17, so the output transport stream is

now composed by the VC 1 and VC 7 and the VC 3 and VC 8 are filtered.

If the transport stream present on the INT 1 is a normal transport stream (NO

MPA) the INT 1 VC pass variable must be set to 0.

3.3 VARIABLE SETTING EXAMPLE

The example below explains how to set a variable of the board.

In this case, the example shows how to set the “ASI 1 to” variable located in the MPX Params

menu section. The procedure to set this parameter is similar to set the other RW variable of the

board. The EK-UNM/3 board is loaded in the slot number four of the EK-MFR/1, so when the EK-

MFR/1 is active on the display it is possible to see:

Pushing the “enter” key (EK-MFR/1 manual, board panel description), the user can enter on the

EKUNM/3 menu (par 3.1). The display shows the first menu of the board (Status)

Using the explore menu keys, it is possible to see every of the four main menu of the board, Status,

Settings, Port Sel and Revision.

The“ASI 1 to” constellation variable is located in the Port Sel menu, so the user must go on this

menu.

28 EK-UNM/3

31/10/2012 Arch. 3828 601-000160/MN Rev. D

The Port Sel menu is showed on the EK-MFR/1 display, so pushing the enter key it is possible to

enter in every sub menu of the Port Sel main menu as “ASI 1 to”.

The “ASI 1 to” variable is set to the VC1 value as default. We suppose to switch the value on the

VC2 value.

EK-UNM/3 29

601-000160/MN Rev. D Arch. 3828 31/10/2012

To change the default value displayed it is necessary pushing the enter key. The variable value

flashing and using the modify variable keys it is possible to set the parameter on the VC2. When the

value is displayed, pressing the enter key it is possible to confirm the change (as the next figure

shows). If the Esc key is pressed the display return the previous value.

4. REMOTE CONTROL

The board can be controlled using two different ways:

Eurotek MST, an application that permits to manage and monitor all the board functionalities (Parameter settings, Internal connections, Log analysis, Software upgrade,

etc…), for more information see the Eurotek MST user manual.

Web Pages, using a standard web browser it is possible to see the web pages showing all the board parameters (see EK-MFR/2 user manual, web interface chapter), with limited

functionalities respect to the Eurotek MST.

APPENDIX A EK-UNM/3 APPLICATIONS EXAMPLE.

In the figure above is reported an example of EK-UNM/3 utilization.

There are two sites, A and B. Any sites is composed by one EK-MFR unit loaded with an EKUNM/3

in the slot number four.

An ASI transport stream of about 5 Mb/s, present on the ASI 2 IN connector, is mapped in the VC1

of the MPA section. Simultaneously an Ethernet packet flow, coming for example from a PC (LAN

A) is mapped into the VC5.

32 EK-UNM/3

31/10/2012 Arch. 3828 601-000160/MN Rev. D

The above settings can be grouped in the next table:

EK-UNM/3 SITE A SETTINGS

Port Sel Mod In = MPA

MPX Params

Asi 2 to = VC1

Gbe to = VC5

Asi 2 BW = 6.0 Mb/s

ETH Params

LAN Port Mode = Auto Neg

WAN PID = 8100

WAN Bit Rate = 100.0 Mb/s

The Asi 2 BW is set to 6.0 Mb/s, so we obtain a margin of 1.0 Mb/s for the “Asi 2 to” MPA input.

In according with the EK-UNM/3 SITE A Settings, we can calculate the bandwidth margin available

for the modulator incoming payload (Mod BW Margin).

To obtain this value we apply the formula reported at the paragraph 3.2 (see Mod BW Margin):

Mod BW Margin = [(Mod Out BR-0.5)*183/188]-[Σ BW + WAN Bit Rate]

Mod Out BR = 115.1 Mb/s (value read in the corresponding status field).

Σ BW = ASI 1 BW + ASI 2 BW + INT 1 BW + INT 2 BW, in this case:

Σ BW = 0 Mb/s + 6 Mb/s + 0 Mb/s + 0 Mb/s = 6 Mb/s

WAN Bit Rate = 100 Mb/s

We obtain:

Mod BW Margin = [(115.1 Mb/s -0.5)*183/188]-[ 6 Mb/s + 100 Mb/s] = 5.6 Mb/s

This value is exactly the value reported in the Mod BW Margin status value.

The payload is modulated and transmitted by a radio link to the site B.

The signal received is firs demodulated and then demapped by the DMA unit, the table below list the

settings for the EK-UNM/3 located in the site B.

EK-UNM/3 SITE B SETTINGS

Port Sel

Dem In = IF2

ASI 1 Out = VC1

GbE = VC5

The Asi 1 Out is set to the VC1,so the transport stream ASI transmitted at the site A is received and

carried out on the Asi 1 output connector.

The GbE is switched on the VC5, so the Ethernet packet data flow transmitted at the site A are

received and carried out on the RJ45 Ethernet connector located on the EK-UNM/3 board present at

the site B.

EK-UNM/3 33

601-000160/MN Rev. D Arch. 3828 31/10/2012

The payload composed by a transport stream ASI and an Ethernet packet data flow and modulated at

the site A is correctly received and demodulated at the site B.

Continuing to observe the figure, it is possible to view the bidirectionality of the EK-UNM/3 board.

At the site B an Ethernet packet data flow (LAN B) is present at the RJ45 connector.

These packets are sent to the modulator unit, the table below reports the settings for this operation:

EK-UNM/3 SITE B SETTINGS

Port Sel Mod In = GbE

The Ethernet packet are modulated and transmitted to the site A.

The EK-UNM/3 located in the site A receives and demodulates the signal coming from the site B.

EK-UNM/3 SITE A SETTINGS

Port Sel GbE In = Dem Out

The above setting allows to carry out on the EK-UNM/3 site A RJ45 connector the ethernet packet

transmitted at the site B.
