INTRODUCTION
The DTR100 multimode VHF transceiver is a state-of the-art communication unit, specifically
designed to operate as radio core part of Air Traffic Control ground stations. It may be regarded
as an integrated transmitter and receiver device, since the internal transmit and receive sections
operate independently.
Thanks to its DSP-based architecture, software-radio approach, and modular design, it allows
for easy update and re-configuration.
The equipment has been designed to fulfil operating requirements in any possible system
layout.
In the transmitter section, the equipment has outstanding performances in terms of noise
radiation and unwanted emissions. These features, together with the high grade of immunity to
external interference of the receiver section, allow for meeting considerable co-siting
requirements under EMC-critical equipment arrangement.
DTR100 belongs to the latest OTE's ATC third-generation communication systems family,
together with the DR100 (VHF receiver), and DT100 (VHF transmitter).

2.2
ESD
No ESD precautions have to be taken by the operator in the daily use of the equipment. The
equipment is designed and manufactured in such a way to not be sensible to electrostatic
discharges.
2.2.1
ESD precautions
The equipment includes many electrostatic-sensitive parts that must be handled at a staticsafeguarded working area. Furthermore, they must be arranged in static-safeguarded
packages, either in the case of storing, or in the case of shipment.
These recommendations should be followed with the maximum care, especially in the case of
modules or board extraction and handling.
A static safeguard area may be intended as:
• Grounded static dissipating wrist-strap that drains static charge from the operator wearing it.
• A work surface covered with or composed of a grounded, static-dissipating material that
drains electrical charges from devices placed on the surface.
Work surface should provide a standard-size ESD-safeguard snap suitable for snap-stacking
wrist-strap connection. It should be used as a convenient ESD caution, whenever handling
modules and boards. These recommendations are to be extended also to activity not strictly
performed in close equipment surrounding. If removed, replaced, or located inside workshop,
any board should be handled by means of convenient ESD cautions.
WARNING
4bs-tz000009-e
Issue 01 – May 2003
Please note that OTE disclaims any responsibility for problems due to
poor ESD protection during activity.

3. OPERATION
The purpose of this section is to describe the operational management of the DTR100,
specifically control and indicator devices and operating through the control panel facilities
3.1
OPERATING STATES AND EQUIPMENT ACCESS POINTS
The equipment can be set in two different operating states:
• ON Line state if the AF line port, located onto the ALB-M rear panel, is used to manage the
AF+signaling connection, e.g. carrying PTT input and the TX and RX balanced audio lines.
• OFF Line state if the Headset/Microphone connector, located onto the Control Panel front
side, is used to manage the AF+signaling connection, e.g. carrying PTT input and the TX
and RX audio. In this operating state, the AF line port located onto the ALB-M rear panel is
not enabled, this meaning that the equipment can not provide service to an operator located
at a remote position. Although full management of equipment audio facility is possible in
OFF Line state (e.g. by Headset), this is the typical operating state to be used for activities
performed locally.
Concerning O&M functions, the equipment can be managed from the Control Panel (CP) by
using the keyboard. It is intended as an easy and immediate access point.
When performing O&M tasks, it is important to note that all equipment functional parameters
can be accessed only in OFF Line state. See next chapters for further details about editable
parameters.

START-UP PROCEDURE
If the equipment is powered only by AC, please refer to the following steps.
• Set ON the external AC breaker or AC power source.
• Set ON the AC switch on PS module.
• Wait until the equipment booting is completed, and the display shows the default window,
with operating mode, frequency, etc. If no alarm is present, operate the equipment.
If the equipment is powered by both AC and backup DC, please refer to the following steps.
• Set ON the external AC breaker or AC power source.
• Set ON the external DC breaker or DC power source.
• Set ON the AC switch on PS module.
• Set ON the DC switch on PS module.
• Wait until the equipment booting is completed, and the display shows the default window,
with operating mode, frequency, etc. If no alarm is present, operate the equipment.
Please note that the equipment is not serviceable until the start-up phase is completed.
WARNING
Do not turn OFF the AC switch when the equipment is operating with both
AC and backup DC.
The equipment is designed to be powered with DC only for backup purposes. In case of AC
source lack, the PS module is automatically supplied by the backup DC power source, and
equipment reduces the RF power output to + 46 dBm (approx. 40 W CW) max.
To power-down the equipment (if powered by both AC and backup DC), operator must before
set OFF the DC and AC switch, and then set OFF the DC and AC breakers or power sources.
It is important to note that any maintenance action on the equipment must be done only after
switching OFF the external AC and DC breakers.
WARNING
4bs-tz000009-e
Issue 01 – May 2003
The PS module does not fully disconnect the equipment from both AC
and DC sources, even when front side switches are in OFF position.
Internal modules and/or parts should be removed from the equipment
only once that the external AC and DC breakers have been switched OFF,
and/or external supply sources have been disconnected.

Radio frequency
Radio frequency connections are located on the middle rear side of the equipment as shown in
the following figure.
Figure 4.3 - DTR100 radio frequency connections
RX Low sensitivity input (SMA-female). By this port, the receiver is fed by the normal input,
having equipment rated sensitivity features.
RX High sensitivity input (SMA-female). By this port, the receiver is fed by the high-sensitivity
input, but it is important to note that this connection bypasses the first RX front-end cell, thus
having less protection wrt interfering signals, e.g. radiated carrier from co-located transmitters.
This input must be used only when the receiver is connected to an external band-pass filter (e.g.
cavity filter).
TX/PA output (N-female). This port is the TX/PA direct radio frequency output.
RF switch connectors. The internal RF switch has a normally-closed SMA port (to be used for
the receiver section, by fitting the external coaxial SMA-SMA jumper), and a normally-open
SMA port (to be used for the transmitter section, by fitting the external coaxial SMA-N jumper).
The switch common port is then available on an N-female port, to be connected to the radiating
system (or the filtering device, etc).
By using this layout the equipment fully operates as "transceiver", device, in which the
transmitter and receive sections share the same radiating system. As factory-default (see the
above figure), the equipment is provided with common TX/RX coaxial port (jumpers present),
the normally-closed port is routed to the receiver low-sensitivity input.

SETTINGS AND ADJUSTMENTS
Following chapters detail necessary information for proper setting-up of the equipment, by
defining a step-by-step procedure.
Setting-up is intended as the sequence of alignment and configuration actions that must be
performed by operator in order to put the equipment in service.
4.2.1
E&M line interface settings
ALB-M card feature dip-switch banks to match AF line interfacing requirements. Line interfacing
adjustments concern E line and M line settings.
To perform the setting, the card must be previously removed from the equipment rear side.

E line is used to acquire PTT signaling from TELCO line. The circuit design is based on a
current detector; the line polarization can be either due to external or internal voltage, as shown
in the figure.
Figure 4.5 - E line circuit layout
In the first case, the presence of an external voltage makes the current flow in the loop; in the
second configuration ALB-M powers the line and external equipment closes the loop. The
proper configuration can be selected setting contacts 1 to 3 of SW01 according to the table.

When external voltage configuration is used, a voltage from 12 to 48 VDC can be applied to E
leads. The applied polarity can be positive or negative. Contacts 5 to 8 of SW01 must be set
according to external applied voltage value as from configuration given in table below.

When internal voltage configuration is used, the voltage applied is +12V. Dip-switches 5 and 6
of SW01 are not relevant; only 7 and 8 can be set. Setting on contact 7 reduces the series
resistance of about 70% (from 800 Ohm to 220 Ohm). Setting on contact 8 reduces to zero the
series resistance. This setting can be useful when using long cables that have a series
18
resistance not negligible .
M line is used to send squelch signaling towards remote device through the TELCO line. The
circuit design is based on an electronic switch. The line can be interfaced in either "floating" or
"common ground" layout
Figure 4.6 - M line circuit layout
In the first case both leads of M line are related to voltage potentials of the external equipment,
and are not referred to ALB-M potentials. In the second case, a dedicated wire for return path is
not present, but the current loop is anyway closed through isolated ALB-M ground. In this
configuration, isolated ALB-M ground and external equipment ground reference must be at the
same potential.
19
When activated, M line interface makes a short circuit on the loop, making current flow .
18
This setting can be useful when using long cabling having a series resistance not negligible (e.g. a connection of 5
Km with AWG24 wire, 0.205 mm2 section, has (84Ohm/Km x 5Km) x 2 = 840 Ohm series resistance).
19
The current flow takes place independently from the line polarity. The residual voltage is 2.5 V @ 20 mA.

Equipment adjustments
The following procedure lists the operating parameters (e.g. frequency, modulation depth, etc)
that must be adjusted according to system layout requirements. In any case, further nonmandatory adjustments (e.g. loudspeaker volume, earphone volume, etc) may be done
according to user criteria, referring to section § 3 - Operation.
Any setting-up activity must be done only after than installation has been completed, thus also
including the connection to any external device and the alignment of ancillary devices (filters,
radiating system, etc). Setting-up is listed in following procedure.

This parameter is used to assign a specific physical ID address on the DIAG port, within the RS485 multi-drop
connection to an external controller. If no controller for remote O&M activity is present, this setting is not necessary.
24
This parameter is used to assign a specific logical ID address on the DIAG port, within the RS485 multi-drop

25
Transmission timeout sets the maximum elapse of time allowed for transmission. At timeout counter expiring,
transmission is shut-down. Short timeout values can affect the equipment service by truncate radiated speech. It is
also possible to set the PTT Timeout OFF by setting the relevant parameter to 0, thus allowing for continuous
transmission operating. Although this setting is not recommended, it can be required for special application (e.g.
VOLMET, etc).
26
Setting of maximum modulation depth is anyway referred to a nominal AF input of -10 dBm. Baseband module
internal process operates as compressor/limiter device, avoiding modulation rate to override 95% and causing overmodulation phenomena.
27
It operates a gain or attenuation on the TX AF line coming from the VCSS. It must be set according to the expected
nominal AF level of the line.

It is important to note that many of the above parameters do not need to be changed from the
default settings for a correct operating, and therefore some of the above steps may be ignored.
In example, default value of squelch threshold is -107 dBm. This value allows for correct
operating in standard operating condition, and it is not necessary to change it.
4.2.2.1
Reference oscillator monitoring
This adjustment must be done with the equipment ON. The front side test port has a monitoring
facility for the internal 10 MHz reference oscillator that has a rated 1 ppm accuracy. When
operating in in 25 kHz channel spacing mode 5 ppm accuracy is required; when operating in
8.33 kHz channel spacing mode 1 ppm accuracy is required.
On the TEST port, a TTL-level 500 KHz square-wave signal is available, obtained by dividing
32
the internal reference . As specified, the counter used for the test must have an internal time
-7
base stability better than 0.1 ppm (1 x 10 ); it is recommended to use a counter provided with
internal high-stability oven, or slaved to external reference (e.g GPS).
It is necessary to wire a cabling having on the equipment side a Mini-DIN 8-pin male, and
having on the frequency counter side the relevant termination (e.g. BNC coaxial). Cabling
should be realized preferably with RF-coaxial cable. The pin 3 of the TEST port must be
connected to the central conductor of coaxial, while pins 1, 4 or 6 (corresponding to GND) must
be connected to the shield. Once realized the cable, the procedure for monitoring and
adjustment is given in the following table.

ON Line is the normal operating condition.
31
Logout is mandatory for permanently storing of the edited parameters.
32
The frequency accuracy can be monitored and adjusted even by checking the effective frequency precision of the
radiated carrier, e.g. by connecting a radio test set on the transmitter RF output.
