The following table summarizes the results of the calculations carried out assuming:
• zero losses between the output connector of Teko equipment and the input connector of the antenna
• maximum gain estimated for outdoor Antenna Gi = 19dBi (for each band)
• maximum gain estimated for indoor Antenna Gi = 7dBi (for each band)
• no co-location or operation in conjunction with any other antenna or transmitter.
Please note
The following table is not meant to represent the actual compliance distance from a particular Teko Optical System or Modular Repeater,
being antennas, cables, and other RF components not provided with Teko equipment.
The actual compliance distance from a particular equipment can be calculated in the final installation phase only - when antenna, cables and
other RF components specifications are available.

Please note
• Fixed stations operating in the 1710-1755MHz band are limited to 1W EIRP and to a maximum antenna height of 10meters above ground
• Regarding to Public Safety bands, to be compliant with 90.217 d)7), signal booster passbands are limited to the service band or bands
for which the operator is authorized. In general, signal boosters should utilize the minimum passband that is sufficient to accomplish
the purpose. When booster encompasses both commercial bands and public safety bands (SMR800/SMR900) has to be installed in DAS
(Distributed Antenna system) indoor system.
• Regarding to Public Safety Bands, the output power capability of the Public Safety signal booster is designed for deployments providing
a radiated power not exceeding 5W ERP for each retransmitted channel.
An example for Low/Enhanced Power, Very/Very Very High Power Amplifier and Donor Front End final installation is provided:
maximum radiated power: 5W ERP = 8.2W EIRP = 39dBm
For remote with splitter and more than one antenna:
G + Pout+ A - 10logN ≤ 39 ⇒ G ≤ 39 - (Pout+A-10logN)
with G = max gain (dBi), Pout = max signal booster output power (dBm), A = attenuation (dB), N = number of carriers
for Very High Power Amplifier we suppose an attenuation (due to cable insertion, splitter, etc.) of 12dB.

The Manufacturer’s rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present,
the rating would have to be reduced by 3.5dB, especially where the output signal is re-radiated and can cause interference to adjacent band
users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device.
La puissance de sortie nominale indiquée par le fabricant pour cet appareil concerne son fonctionnement avec porteuse unique. Pour des appareils
avec porteuses multiples, on doit réduire la valeur nominale de 3,5dB, surtout si le signal de sortie est retransmis et qu’il peut causer du brouillage
aux utilisateurs de bandes adjacentes. Une telle réduction doit porter sur la puissance d’entrée ou sur le gain, et ne doit pas se faire au moyen d’un
atténuateur raccordé à la sortie du dispositif.

Components & Solutions
The Teko Platform is a versatile, modular, multi-technology platform designed to offer flexible
and reliable wireless coverage and capacity for both indoor and outdoor environments. Teko’s
design delivers the maximum end-user performance, supporting Time Division LTE technology
and LTE-Advanced capabilities to enable multi-path performance with the flexibility to adapt
coverage and capacity in any venue on an event-by-event basis.
The DAS (Distributed Antenna System) Platform is made up of two main elements: Master
Unit and Remote Units.
Teko Master Unit
The Master Unit is a rack-based platform delivering modularity that allows configurations
for different needs and a future-proof design to ensure you can adapt your venue to future
technologies. The Master Unit is configured to provide both the RF interface (off-air and/or
via coaxial cable) towards the signal source (BTS, NodeB, Donor) and the optical interface
towards Remote Units. It also hosts the Supervision Module for the management of the entire
System utilizing secure browser technology that enables administration from any location.
The Master Unit can be configured utilizing Donor Front End, Active Point of Interface or DAS
Trays to provide flexible options to connect to any combination of Carrier interfaces. The Teko
Platform also includes the optional Multiband Spectrum Analyzer (MSA) to allow recordable
and remote monitoring of venue performance to enable easy optimization.
Architecture
The modular sub-rack allows adaptation of deployment needs including the addition of newer
technologies within sub-racks that prepares venues to be more adaptive to venue needs
(e.g. new sectors) and to introduce newer services into the existing venues DAS. The Master
Units DAS shelf and architectural design minimizes system footprint, saving 30-70% of critical
space requirements within venues, BTS Hotels, Co-location environments. The Teko system
design allows for passive repeater or active / optical DAS configurations and the system can
be reconfigured as needs change.
Teko Remote Units
Remote Units (RUs) are connected to the Master Unit via a single mode optical fiber to
distribute multiple frequency bands and multiple Carriers/MNOs to each Remote Unit, or to
multiple RUs to configure multipath (e.g. MIMO) configurations.
Remote Units are self-contained and provide signal distribution to a range of both indoor and
outdoor antennas.
As integral elements of the system all Teko Remote Units can be configured from a single

components can be assembled to provide Optical Systems (DAS) and rack mounted modular
Off-air Repeaters to improve coverage in different environments.

administrative interface at the master units. This includes applying new firmware versions to
the Teko system and its RUs.
Multi Power Options
Teko Remote Units are available in different power classes using multi-carrier amplifiers that
can be driven simultaneously by the same Master Unit. This provides a flexible solution to
distribute capacity or extend coverage into different locations (indoor and outdoor) at the
same time, for example in tunnels, undergrounds, airports, high rise buildings, shopping
malls and campuses.

Components & Solutions
The components of the Teko Platform can be grouped into the following categories:
1. Modules providing the RF interface towards the signal source
• DAS Tray Point of Interface (TDTPOI) module: is the single-band/single-operator
interface used in Optical DAS to directly (no external directional coupler nor load needed)
interface up to 2 BTSs or NodeBs/e-NodeBs, either duplex or simplex, with or without
diversity, SISO or MIMO 2x2.
• Point of Interface (POI or TAPOI) module: is the single-band/single-operator interface
towards a BTS or NodeB/e-NodeB. The Point of Interface module is connected to the
signal source via coaxial cable.
• Digital Donor Front End Module: is the single-band/single-operator interface towards a
Donor Antenna, providing a connection to a BTS or NodeB/e-NodeB over an air link.
2. Equipment extending coverage / distributing capacity
• Service Front End: is the single-band/multi-operator interface towards a Service
Antenna. It provides wireless signal to the area to be covered (Modular Repeaters). In
Optical Systems the Service Front End can be used to extend coverage to the area close
to the Master Unit site.
• Remote Unit: is the multi-carrier equipment used in Optical DAS to distribute wireless
signal throughout the area to be covered.
3. Modules providing the optical interface towards Remote Units
• Fiber Optic Transmitter/Receiver Modules are the optical interface between Master Unit
and Remote Units: they provide RF-to-Optical/Optical-to-RF conversion.
• Master and Slave Point to Point Modules perform the RF-to-Optical/Optical-to-RF
conversion required by the optical point to point link connecting RF Interface modules to
distant Fiber Optic Transmitter/Receiver Modules. The optical point to point link allows a
separation distance -up to 20km- between RF Interface modules and Fiber Optic Modules.
4. Passive Modules providing distribution and filtering
Our passive components provide RF distribution and filtering.
Due to the flexible configuration options of the Teko Platform, the same passive components
can be used for different purposes.
• The 2-way/4-way Combiner/Splitter can be used to manage either up to 4 RF interface
modules, operating in the same band (Multi-Operator Systems) or up to 4 Fiber Optic
Modules (Fiber Optic Transmitter/Receiver Modules or Master Point to Point Modules).
• The Band Splitter/Combiner -Triplexer (with built-in 1:4 Splitter/Combiner) can be
used to manage up to 3 RF interface modules or Service Front End subracks, operating
in different bands (and up to 4 Fiber Optic Modules). It can also manage up to 3 four-way
TEKO DAS Platform

page A13
Components & Solutions
splitter/combiner modules each connected to multiple RF interface modules, operating
in the same band (and up to 4 Fiber Optic Modules).
• The Pentaplexer (Esaplexer) can be used to manage:
ÌÌ either up to 5 (6) RF interface modules operating in different bands
ÌÌ or up to 5 (6) Service Front End subracks operating in different bands
ÌÌ or up to 5 (6) four-way splitter/combiner modules used to manage multiple RF interface
modules (up to 4 for each band).
5. Modules for the management of the System
• A single Supervision Module allows the management of the whole Coverage System. A
Light Supervision is available for modular repeaters or small/medium DAS.
• The Alarm Module is an optional module that can be equipped to increase the number
of supported external alarms.
6. Power Supply Components
Our Power Supply Components include:
• AC/DC and DC/DC Power Supply modules, to be equipped inside Active subracks. Each
module provides up to 100W output power; several modules can be connected in parallel
to obtain the power required by the System (please refer to the Teko platform datasheet
for details about derating factors).
• AC/DC and DC/DC space efficient Power Supply Subracks, providing up to 2.4kW (AC/
DC) / 3kW (DC/DC) maximum output power in just one height unit space.
• A centralized Power Supply distribution solution for the remote powering of 48VDC Low
Power Remote Units.
The most suitable solution can be selected, according to the System total power consumption
and to the installation requirements.
7. Subracks hosting the System modules
Both active and passive subracks are available.
• Active subracks are provided with a backplane that allows the management and power
supply of active modules.
• Passive subracks are used to host passive modules that do not require power nor management
to function. Passive Subracks allow a reduction in the cost of the whole system.
8. Forced-air cooling Subrack
A forced-air cooling subrack is available to ensure the air flow required for proper cabinet
installed equipment operation.
Rack cabinets for hosting the System Subracks (indoor installation) and cabinets for Outdoor
installation are also available.

A.2.1 Modules providing the RF interface towards the signal source
• DAS Tray Point of Interface (TDTPOI) modules
DAS Tray Point of Interface modules are used in Optical DAS to directly (no external directional
coupler nor load needed) interface any kind of operator signal source: BTS or NodeB/e-NodeB,
either duplex or simplex, with or without diversity, SISO or MIMO 2x2.
The TDTPOI-x-D (x=operating band) can be connected either to two SISO BTSs (with or without
diversity) or to one MIMO BTS. Dual TDTPOI models, geared to pick up the TDD reference
signals from BTS, are also available (please refer to Paragraph A.2.5).
TDTPOI are equipped with software-controlled attenuators for Downlink and Uplink RF levels
adjustment via the Coverage System Supervision Module and Management Tools.
RMS/Peak detectors and power limiter features enable monitoring of DL and UL signals. Userdefined thresholds allow for alarms to be generated and protection to the DAS system from
overpowering.
The Platform can be equipped with one DAS Tray or more to make multiple configurations
available: single operator (single-band / multi-band) and multi-operator (single-band / multiband).

• Teko Digital Donor Front End (TDFE)
The Digital Donor Front End Module is the single-band/single-operator System RF interface
towards a Donor Antenna, providing Downlink digital filtering and Uplink Power Amplifier.
No physical connections are required between the DFE and the cellular network: the Donor
Antenna provides the connection to a BTS or NodeB/e-NodeB over an air link.
Coverage Systems can be equipped with one or more Donor Front End modules to make
multiple configurations available: single operator (single band / multi-band) and multioperator (single-band / multi-band).
Figure A10 – Digital Donor Front End (TDFE)
A single-band single-operator modular Off-air Repeater can be set up combining a Digital
Donor Front End Module and a Service Front End (Teko single-band/multi-operator interface
towards a Service Antenna). Up to 4 Donor Front End Modules can be connected to a single
Service Front End to provide a single-band 4-operator modular Off-air Repeater.
Digital Donor Front End Modules can also be used to drive Optical Systems: the Digital Donor
Front End Module allows Optical Systems to be driven without the need of a dedicated BTS
or NodeB/e-NodeB. A donor antenna picks-up the signal and the Optical System acts as a
repeater with distributed Service antennas connected to the Remote Units. Service Front
End subracks can be connected to DFE modules to provide coverage to the area next to the
Master Unit site.

Components & Solutions
Each DFE module hosts the duplexer, to be connected to the Donor Antenna to separate/

In downlink the signal from the Donor Antenna is preamplified by a Low Noise Amplifier and
converted into an IF signal by a down converter. The selection of the band of frequencies or
channels to be extended is handled by a digital filter.
The digital filter can manage 1 variable band or 2 variable sub-bands (standard version). A
fully equipped version is available to manage up to 9 variable sub-bands.
An up converter converts the IF signal into the RF output signal.
In uplink the signal from the Service Front End Subrack or from the Optical System is converted
into an IF signal by a down converter, filtered and re-converted into an RF signal, amplified by
a power amplifier and re-transmitted to the signal source.

Fiber Optic Module alarm status LED:
OFF: regular operation; BLINKING ORANGE/ORANGE: warning/minor;
BLINKING RED/RED: major/critical
These LEDs describe the general operating status of Remote Units (1 to
4) connected to Fiber Optic Transmitters (DL) and Repeaters (UL) .
Each pair of DL/UL leds takes the same color as the general operating status
led of the Remote Unit connected to the optical connector, except when
• a Laser Fault occurs in the Fiber Optic transmitter. If this fault occurs, all
DL leds turn RED and the ALM Led switches on (RED).
• a Low Optical Power alarm arises in the Fiber Optic receiver. If this alarm
arises, the UL led turns RED and the ALM Led switches on (RED).
Each pair of DL/UL LEDs can be:
Green: Remote Unit status OK
Blinking Orange: presence of RU active alarms with warning severity level
Orange: presence of RU active alarms with minor severity level
Blinking Red: presence of RU active alarms with major severity level
Red: presence of RU active alarms with critical severity level

• Master and Slave Point to Point Modules
Master and Slave Point to Point Modules provide an optical point to point link allowing a
separation distance -up to 20km- between RF interface subracks and slave optical subracks.
The point to point link requires the RF interface subracks to be equipped with Master Point
to Point modules and the remote (slave) optical subracks to be equipped with Slave Point
to Point modules. The RF Interface subracks can be equipped with up to 4 Master Point to
Point modules for the management of up to 4 optical subracks, installed in different remote
locations.
Components & Solutions
The point to point link is suitable when the signal source (BTS, NodeB/e-NodeB, Repeater) is
located far from the area to be covered or when the same optical system provides coverage to
several separate buildings; in these applications the point to point link allows the transmission
of signals from/to a group of remote units over a single strand of optical fiber, thus providing
a significant reduction in the number of fiber optics running long distances.
Figure A17 – Point to Point Modules: Master (left) and Slave (right)
Master and Slave Point to Point Modules are connected via a single optical fiber (single-mode
SMR 9/125).
Each Slave optical subrack can be equipped with up to 3 Slave Point to Point Modules for the
coverage of up to 3 sectors.

• Power Supply Subracks
The AC-to-DC and DC-to-DC Power Supply subracks allow a reduction in the amount of
space required for the System installation: they can be equipped with up to 3 Power Supply
modules to provide up to 2.4kW (SUB-PSU-MU)/3kW (SUB-PSU-MU/48) output power in just
one height unit space. Hot-plug 1+1 redundancy feature is supported: load-sharing power
supply modules can be installed to achieve high system reliability. Hot-plugging allows a
faulty power supply module to be replaced without powering off the system.
The power supply subracks allow the reset of the whole Master Unit, or PTP Slave subrack,
from the System management software (OMT webpages / OMC proprietary software).

Components & Solutions
A.3.1 Rack-mounted Modular Repeater
The Teko platform can be configured for RF repeater applications where the need for optimized
signal coverage is adequate to provide better end-user service that is transparent to protocol
and modulation.
Populating the Teko Master Unit with digital Donor Front End (DFE) and service front-end
modules, multi-band, multi-operator coverage solutions can be configured.
The modularity of the Teko platform allows easy adaptability to new technologies or extending
the solutions to additional operators as needed.
No physical connections are required between the Modular Repeaters and the cellular network:
the Digital Donor Front End is connected to a Donor Antenna, providing the connection
towards a BTS or NodeB/e-NodeB over an air link.

TEKO DAS Platform
Multiple DFEs (up to 4) can be connected with a single service front-end for single band,
multi-operator configurations. Multiple service front-ends can be utilized with multiple DFEs
to create multi-band, multi-operator solutions.
When Modular Repeaters do not provide satisfactory coverage (extensive areas, long tunnels),
they can be used along with a fiber fed System (Teko Optical DAS).

Operating principle
Modular repeaters use a directional antenna to interface with the operator’s donor BS and one
or more service antennas to transmit the amplified wireless signal to the area to be covered.
In downlink the repeater receives the signals from the BS, amplifies them and re-transmits
them to the mobiles. In uplink the repeater receives the signals from the mobiles (MS),
amplifies them and re- transmits them to the base station.

• RF interface subracks
RF Interface subracks operate over different frequencies and with various frequency
combinations in the frequency range from 380 to 2700MHz.
Each RF interface subrack can be equipped with one or more RF Interface modules.
Master Unit RF Interface modules can be Point of Interface (POI/TAPOI/TDTPOI) modules and/
or Donor Front End modules.
Master Units equipped with POI/TAPOI/ TDTPOI modules must be installed next to the donor
BTS or NodeB/e-NodeB).
POI modules can be equipped in passive subracks; TAPOI/TDTPOI modules require active
subracks (SUB-TRX).
Donor Front End modules allow the Optical DAS to be driven without the need of a dedicated
BTS or NodeB/e-NodeB: each Donor Front End module interfaces with a Donor Antenna
oriented towards a BTS or NodeB/e-NodeB (connection over an air link).
Active Subracks are required to host Digital Donor Front Ends; fully equipped Digital Donor
Front Ends require deep Active Subracks (depth = 360mm / 14.17in). Each subrack can be
equipped with up to 4 Donor Front End Modules.

A.3.2 Optical DAS
The Teko Platform components can be configured to provide multi-carrier Optical Distributed
Antenna Systems.
Optical Systems are based on the Radio over Fiber technology, which enables radio signal
transmission over optical fiber. This technology offers wide bandwidth and very little loss
along the fiber optic cable, allowing the signals to be propagated over long distances. This
allows extensive areas coverage.
Each Teko Optical DAS is made up of two main parts: the Master Unit, interfacing the signal
source, and Remote Units, distributed throughout the territory to be served. Master Unit and
Remote Units are connected via single mode optical fiber (SMR 9/125).
A – Master Unit
The Master Unit provides both the RF interface towards the signal source (one or more BTSs
or NodeBs/e-NodeBs) and the optical interface towards Remote Units.
It is a rack-based modular equipment: Teko Coverage and Capacity Systems components can
be assembled in a variety of ways providing different Master Unit configuration options.
Each Master Unit can be equipped with one or more RF interface subracks, hosting RF interface
modules and with one or more Optical Subracks, hosting Fiber Optic Transmitter/Receiver
modules.
When the Master Unit is equipped with Master and Slave Point to Point Modules, RF interface
subracks and optical subracks can be separated by a maximum distance of 20km.
TEKO DAS Platform
modules -up to 4 for each band (and up to 4 Fiber Optic Transmitter/Receiver Modules).
• the Pentaplexer and Esaplexer can be used to manage
-- up to 5 (Pentaplexer)/ up to 6 (Esaplexer) RF interface modules operating in different
bands or
-- up to 5 (Pentaplexer)/ up to 6 (Esaplexer) Service Front End subracks operating in
different bands or
-- up to 5 (Pentaplexer)/ up to 6 (Esaplexer) four-way splitter/combiner modules- used to
manage multiple RF interface modules (up to 4 for each band).
The RF Interface subracks can also host up to 4 Master Point to Point modules for the
management of up to 4 optical subracks installed in different remote locations.
Digital Donor Front End modules can be connected to Service Front End Subracks to provide
coverage to the area adjoining the Master Unit site.
Each Service Front End can be fed by up to 4 Donor Front-End Modules interfacing the signal
source. Downlink and uplink auxiliary ports are available to drive the Optical System.

RF Interface subracks also host passive modules providing distribution and filtering:
• Splitter/Combiner
• Band Splitter/Combiner (Triplexer) with or without built-in 1:4 Splitter/Combiner
• Pentaplexer/Esaplexer.
Due to the flexible configuration options of Teko Coverage and Capacity Systems, the same
passive modules can be used for different purposes:
• the splitter/combiner can be used to manage multiple RF interface modules, operating in
the same band (Multi-Operator Optical Systems) or multiple Fiber Optic modules;
• the triplexer (with built-in 4-way Splitter/Combiner) can be used to manage
-- up to 3 RF interface modules operating in different bands (and up to 4 Fiber Optic
Transmitter/Receiver Modules) or
-- up to 3 Service Front End subracks operating in different bands (and up to 4 Fiber Optic
Transmitter/Receiver Modules) or
-- up to 3 four-way splitter/combiner modules, used to manage multiple RF interface
TEKO DAS Platform
• Optical Subracks
Optical Subracks are Active Subracks hosting Fiber Optic Transmitter/Receiver modules.
Figure A53 – Optical Subrack (example)
Fiber Optic Transmitter/Receiver modules are the optical interface towards Remote Units:
they provide RF to optical /optical to RF conversion.
Fiber Optic modules are connected to Remote Units via single-mode optical fiber (SMR
9/125); each Fiber Optic Module can manage up to 4 Remote Units (up to 5 in cascade
configuration).
Up to 6 Fiber Optic Modules can be housed in a single Optical Subrack.
In Downlink RF signals are converted into optical signals in the Fiber Optic Transmitter modules
of the Master Unit and then they are propagated through optical fiber distribution to Remote
Units. In the Fiber Optic Receiver of each Remote Unit, the optical signal is then converted
back into an RF signal that is amplified and transmitted to mobiles through an antenna or a
passive distribution system.
In Uplink RF signal is converted into an optical signal in the Fiber Optic Transmitter of each
Remote Unit and then it is propagated via fiber optics to the Master Unit. Optical signals from
Remote Units are then converted by the Fiber Optic Receiver modules of the Master Unit into
RF signals and transmitted to the signal recipient.
Uplink and downlink optical signals are transmitted over the same single mode optical fiber

The following figure shows the Tri-band wideband Remote Unit block diagram: in down-link
the optical signal from Master Unit is converted into an RF signal by the Fiber Optic Receiver
module. RF signals, filtered by the triplexer, are amplified by Power amplifiers, filtered and
transmitted through an antenna or a passive distribution system.
In up-link the RF signal is filtered by the triplexer. The three RF signals are amplified by
Low-Noise Amplifiers, filtered and then converted into an optical signal by the Fiber Optic
Transmitter module. The signal is transmitted via fiber optics to the Master Unit.

A.3.3 Coverage Systems Management and Power Supply
Coverage Systems can be accessed and managed simply connecting a PC, either locally or
remotely, to the IP address of the System Supervision Module.
The Supervision Module Communication Interfaces (Ethernet LAN port / Modem) allow the
System to be managed either by a Local Maintenance Terminal (LMT), connected locally to
the Supervision Module LAN port, or by a Network Element Manager (NEM). The connection
with a Network Element Manager (NEM) can be either a physical (Ethernet LAN) or a modem
connection.
The optional wireless modem (GSM/GPRS or GSM/GPRS/UMTS), integrated inside the
Supervision module, allows the Coverage System remote management. A VPN application
installed on the Supervision Module provides remote and secure access to the System using
the Internet. An embedded SNMP agent software is available to provide a Northbound SNMP
interface, allowing easy integration into upper level Network Management Systems (NMS).
The management of the System is performed via JMA Wireless Teko OMT (Operation and
Maintenance Terminal) web pages: the Supervision Module is equipped with a web-server and
each component of the System is associated to a web page displaying detailed information
about the component.
OMT web pages show the Coverage System operating parameters and alarm status. They
allow the commissioning, monitoring, setting and troubleshooting of the whole Coverage
System. Please refer to JMA Wireless Teko OMT web pages User’s Guide for details.
Teko Operation Management Centre (OMC) proprietary software allows the management
of multiple Teko Coverage and Capacity Systems in a Network. Please refer to Teko OMC
User’s Guide for details.

ÌÌ Supervision Module
A Supervision module is available for the management of more sophisticated Teko DAS
architectures: the module is able to manage the Active Subrack it is equipped in (Master
Subrack), the power supply subrack, up to other 12 Active Subracks (Monitored Subracks),
and all connected Remote Units.
Figure A60 – Supervision Module with optional wireless modem (left) without wireless modem (right)
Twelve ports (1 to 8 and S1 to S4) are available on the Supervision Module front panel to
be connected to the RS485 ports of monitored Active Subracks.
• Ports numbered from 1 to 8
The ports numbered from 1 to 8 are available for the connection to monitored subracks
mounted within the same rack hosting the Master Subrack.
• Ports numbered from S1 to S4
The other four ports (S1 to S4) are available for the management of remote active
subracks equipped with Point to Point Slave modules.
The Slave Point to Point module installed on the left side of the remote slave subrack
(slots 1 to 6) manages the remote optical subrack, the remote power supply subrack
(if any), and all connected Remote Units. The Coverage System Supervision Module
communicates with the Slave Point to Point built-in Supervision via the single-mode
optical fiber (SMR 9/125), connecting Master and Slave Point to Point modules.
The ports S1 to S4 not connected to remote subracks can be used to manage additional
subracks, mounted within the same rack hosting the Master Subrack.
• Additional RS485 port available on the Master Subrack rear panel
The RS485 connector, available on the rear panel of the SUB-TRX-PSU hosting the
Supervision module, provides an additional port for the management of the power
supply subrack (SUB-PSU-MU or SUB-PSU-MU/48). This port is used only when the
System is equipped with the power supply subrack in addition to other 12 monitored
Active Subracks, connected to the Supervision Module RS485 front ports.

Components & Solutions
The RS485 port, available on the rear panel of a Remote Point to Point Slave Subrack, is
used only when a SUB-PSU-MU or SUB-PSU-MU/48 is installed to provide power supply
to the remote subracks.
Address assignment
Each monitored Subrack takes its address from the Supervision Module port it is
connected to (please refer to Paragraph B.4.2 RS485 Connections for details).
The Active Subrack equipped with the Supervision Module (Master Subrack) takes address
= 0 (zero).
