SAFETY REGULATIONS
Please read this chapter before you install and use this equipment.
To ensure your safety, the equipment has been designed to comply with the
following safety standard:
IEC 60950 Safety of Information Technology Equipment
Before you start to install and operate the modem, please make sure you observe
the following points:
•The equipment described in this manual is designed to be used by properly
trained personnel only. Only qualified personnel who are aware of hazards
involved may adjust, maintain and repair the exposed equipment.
The AZ420 Telco Satellite Modem has no operator serviceable
parts inside. Refer servicing to qualified personnel. To prevent
electrical shock, do not remove covers.
•To use the equipment correctly and safely, it is essential that both operating and
servicing personnel follow generally accepted safety procedures in addition to
the safety precautions specified in this manual. Warning and caution statements
and/or symbols are marked on the equipment when necessary. Whenever it is
likely that safety protection is impaired, immediately switch off the equipment

SHAPING THE FUTURE OF SATELLITE COMMUNICATIONS
1 INTRODUCTION
1.1 Short Description
The AZ420 is a state-of-the-art satellite modem designed for fixed rate telco, voice
and data applications over satellite in full compliance with the DVB standards.
The AZ420 connects directly with terrestrial data and voice networks through a
standard G.703 interface.
In its default configuration, the AZ420 supports E1 rates.
The support of E2, T2, E3 and T3/DS3 rates are available as configuration option.
It is also possible to configure the modem with a secondary G.703 input/output, for
the implementation of a redundant configuration or to allow the modem to be
compatible with two different transmission rates.
At the output of the modulator, the signal is available on an L-band interface.
Extended L-Band, IF band as well as HPA control functions are available as
configuration options. When activated the unique linear and non- linear
predistortion option Equalink™ provides an additional link margin improvement of
up to 2,5dB.
On the receive side, the AZ420 has a dual L-band input (950-2150MHz). The
active L-Band input is selected by the user and can provide DC power and
frequency band selection signals compatible with most professional and
commercial LNBs. Optionally one L-Band input can be replaced by an IF (50 -
180MHz). An adaptive equalizer compensates linear distortion of the transmission
channel and the integrated Noise & Distortion Estimator (NoDE) tool provides an
accurate reading of the satellite link margin even in presence of non-linear
distortion and allows the user to find the optimum input back-off setting very easily
for 16APSK or 32APSK operation, whether or not nonlinear predistortion is applied.
1.2 Key Features
•DVB-S2 and DVB-DSNG/S compliant;
•QPSK, 8PSK, 16APSK and 32APSK;
•G.703 interface with E1, T2, E2, E3 or T3/DS3 rates;
•L-band monitoring output;
•Programmable amplitude slope equalizer;
•Adaptive equalizer (demodulator input);
•Noise & Distortion Estimator tool (NoDE) ;
•Optional Extended L-Band (950 - 2150 MHz);
•Optional 10 MHz reference input/output;
•Optional linear and non-linear predistortion (EqualinkTM).pricing and software

SHAPING THE FUTURE OF SATELLITE COMMUNICATIONS
2 INSTALLATION
2.1 Rack Mounting
The equipment is designed to operate in a 19-inch rack system conform to IEC
60297. When mounted in a standard 19-inch equipment rack, make sure you
sustain it with L-profiles. Do not fix the modem with four front panel screws only,
since this will damage the modem and could result in self injury.
It is allowed to operate the equipment in transportable installations and vehicles
equipped with the means to provide a stable environment. Do not operate the
equipment on vehicles, ships or aircraft without the means of environmental
conditioning, as this may invalidate the safety compliance.
Mount the equipment in the rack in such a way that the amount of air flow required
to safely operate the equipment is not compromised.
2.2 AC Power Supply
This equipment is provided with a protective earthing incorporated in the power
cord. Be careful to insert the mains plug only in a socket outlet provided with a
protective earth contact (TN type power supply). Any interruption of the protective
conductor inside or outside the equipment is likely to make the equipment
dangerous. Intentional interruption is prohibited.
Install and connect the equipment to the mains power supply system in compliance
with local or national wiring installation standards. Position the equipment so that
the mains supply socket outlet for the equipment is near the equipment and can
easily be accessed or that there are other suitable means to disconnect from the
mains supply.
The power supply is set to operate from 100 to 240Vac to 47-63Hz.

SHAPING THE FUTURE OF SATELLITE COMMUNICATIONS
2.3 Cable Distribution System
Install the equipment in accordance with the applicable provisions of NEC Article
810 for US and with CEC section 54 for Canada. Before connecting the coax to the
equipment, make sure that the equipment is properly earthed. The screen of the
used coax cable should be grounded according to the local regulations.
2.3.1 Technical Earth
On the rear panel of the equipment a technical earth is available (an unmarked
terminal on the right side of the equipment). It is provided to:
•Ensure that all equipment chassis fixed within a rack are at the same technical
earth potential. This is done by connecting a wire between the technical earth
terminal and a suitable point on the rack.
•Eliminate the migration of stray charges when connecting between equipment.
