2. INTRODUCING ION-B
2.1. THE FEATURES
ION-B is an innovative platform designed in order to provide an effective and flexible
coverage to a large variety of indoor scenarios.
Thanks to its high modularity, its low power consumption, and its full-transparency to
protocols and modulation formats, ION-B is the perfect plug&play solution to
distribute any wireless standard (including GSM, GPRS, EDGE, CDMA, W-CDMA,
and LTE to the in-building environments requiring reliable and interference-free
communications, as well as high traffic capacity and maximum flexibility about future
expansions.
These unique features make the ION-B platform suitable also for applications to
critical areas experiencing difficulties in establishing and keeping phone calls, while
its compact design always guarantees a minimum aesthetic impact.
2.2. BRIEF DESCRIPTION OF ION-B
ION-B is a Distributed Antenna System (DAS) based on the Radio-over-Fiber (RoF)
technology, and capable of carrying wireless mobile signals through the 700MHz -
2700MHz frequency range regardless of their protocol and their modulation format.
The system has two basic components, a Master Unit and a Remote Unit. The
Master Unit is made of one or more subracks typically connected to the BTS (Base
Transceiver Station) through either a repeater (RF interface) or a coaxial cable.
Each Remote Unit is connected with a dedicated pair of single-mode optical fibres
(one for UL and one for DL) to the Master Unit. These optical fibres work on 1310 nm
wavelength and provide low losses and almost unlimited bandwidth, available for
future system developments.

User’s Manual for ION-B Systems
Page 22 ION-B User Manual (MN024-15)_n_20150730.docx
ION-B is a modular system whose basic components are:
one Master Unit made of one or more subracks, each providing 12 module slots.
Each slot can host either an active or a RF passive device (chosen among the
wide range of ION-B options), in order to meet the planned design requirements;
a variable number of Remote Units (TFAx), whose function is feeding the antenna
passive network;
a proper number of indoor antennas, suitable to provide radio coverage to the
area. ION-B is fully compatible with any type of indoor antennas;
the optical cables required to connect the 19” subracks to the TFAx.
2.3. ION-B FEATURES
The following lines report a brief summary of ION-B main features:
multiband 2G, 2.5G, 3G, and 4G compatible: ION-B is completely transparent to
any transmission protocol and modulation format, and it can distribute any 2G,
2.5G, 3G, and 4G wireless standard. In addition, it allows to carry also the WLAN
(802.11b/g) service over the same infrastructure;
modular configuration for flexible design: by properly setting some parameters like
the amount of RUs and the antenna locations, the ION-B architecture can follow
the environment specific features in order to obtain the most effective radio-
coverage of the indoor area. The modularity of the system allows easy
modifications for future growth and increasing traffic;
easy to install: the intelligent plug & play ION-B system includes an Automatic
Gain Control (AGC), that eliminates system gain variations regardless of optical
loss. This avoids the need for field adjustments, thus reducing design, installation
and optimization time.
low-power consumption: establishing a “quasi line-of-sight propagation” towards all
mobile phones inside the area, ION-B works with low power levels. Low power
levels have two great advantages: 1) allow mobile phones to work at lower power
levels, thus limiting the radiated emissions and increasing their battery life; 2) allow
a better control of interference effects between adiacent cells.
central supervision functions: all individual alarms of ION-B system are available to
both local and remote connections. Detailed alarm information is provided by
special software (i.e. by Supervision or Maintenance software tools) running on a
locally connected host, as well as any information about alarm status and alarm
history is available to remote connections via TCP/IP protocols, SNMP agent, or
HTTP servers. This alarm information is visible also by means of LEDs present on
the front panels of both the MU and the RUs;
multiple-carriers system: there are no restrictions on the number of carriers that
the ION-B can convey. Obviously, the more carriers per service, the less power
per carrier;
remote power supply: in case mains cannot be used for the Remote Units, ION-B
offers a centralised power supply option, which distributes both a DC low-voltage
(-48V) power and the optical signals through a composite fibre optic/copper cable;
User’s Manual for ION-B Systems
ION-B User Manual (MN024-
15)_n_20150730.docx Page 23
wide variety of RF passive devices: the connections between the DAS and the
local BTSs are able to be arranged so as to get the best fit for the customers
needs. ION-B equipment provides RF splitters/combiners, cross band couplers,
attenuators, and duplexers for UL/DL paths, thus allowing maximum in design
flexibility;
high reliability: high MTBF (Mean Time Between Failure).
2.4. TYPICAL ION-B APPLICATIONS
Due to its unique features, the ION-B is an ideal solution for radio coverage in a
variety of situations:
Multi-operator shared infrastructures: each mobile operator has its own carrier which
needs to be transported without interfering with the others. The ION-B is capable of
transmitting multiple carriers simultaneously while providing independent level
adjustments for each of them, ensuring maximum performance and reducing
infrastructure costs.
High rise buildings: RF signals from surrounding macrocells or external BTSs are
usually quite strong inside high rise buildings and can cause so much interference
that indoor mobile communications often become impossible. By strategically placing
antennas along the exterior walls of the building, the signal to noise ratio can be
optimized. This interference control solves many problems, such as the “ping pong”
effect that sometimes is experienced when a mobile frequently changes from indoor
to outdoor coverage.
Exhibitions, conventions, and shopping centers: the critical aspect of these
environments is their high traffic loads, which are furthermore also highly variable.
Thus, the main goal in these cases is to set up radio coverage enabling the effective
management of these variable traffic loads, with neither undervalued nor overvalued
infrastructure expenses. A unique feature of the ION-B is that RF frequencies can be
allocated quickly when and where they are needed, thus reducing implementation
costs. This makes the ION-B an ideal solution for temporary or last minute requests
(such as conferences).
Airports: require both modular and flexible radio coverage in order to meet their
current needs while also foreseeing future expansions. The ION-B is able to manage
heavy traffic loads, providing a high level of quality with minimum environmental
impacts, its modularity also allows for future expansions.
Corporate buildings: inside a corporate building, frequent disruptions during mobile
communications may limit business transactions. These environments are often
complex and densely populated while having specific requirements: heavy traffic
capacity, high expectations regarding quality of service, full compatibility with
wireless standards and future expandability. The ION-B guarantees high quality radio
coverage in all of the above conditions and maintains maximum flexibility while
managing any possible traffic conditions.
Subways and densely populated metropolitan areas: These areas are distinguished
by large surface areas, and may require RUs to be placed far away from the BTSs.
The ION-B guarantees signal integrity for distances up to 3km, while through the
wideband interconnect link option, distances of 20km can be reached. Moreover,
User’s Manual for ION-B Systems
Page 24 ION-B User Manual (MN024-15)_n_20150730.docx
these environments require gradual investments, because initially operators tend to
provide radio coverage only in the busiest areas, and then extend it in order to reach
complete coverage later.
The modularity of the ION-B helps operators to gradually expand the system. Often,
large cities set up seamless and reliable radio systems for emergency services. In
these cases, the required RF infrastructure needs to be unobtrusive and
environmental friendly; this can be achieved using an ION-B DAS. When redundancy
is required, two interleaved ION-B systems can be used, management and
supervision for these systems can be remotely established by means of an external
modem and an open protocol such as SNMP.

3. EQUIPMENT OVERVIEW
3.1. INTRODUCTION
The basic components of an ION-B system are the following:
a Master Unit, able to bring the mobile signals from the BTS to
different Remote Units and vice-versa, thus remotising the distribution
and collection of any mobile signals via fiberoptic cables;
a variable number of Remote Units, conveying and receiving mobile
signals through low-power antennas.
A brief introduction to the main components of the ION-B system’s Master and
Remote Units is presented in the following section. The details of each component
can be found in the subsequent sections of this manual.

Figure 3-5 Case-R4E Remote Unit Figure 3-6 Case-U Remote Unit
The Remote Unit (TFAx) is a device which provides optical-to-electrical downlink
conversion and electrical-to-optical uplink conversion, thus allowing a bidirectional
transmission of signals between the Master Unit and the remote antennas. It is
available in 3 different power configurations (Low/Medium/High), housed by 5
different architectures (Case A, Case B, Case R2, Case R2E, Case R4E, and Case
U), so as to fulfill different coverage and band requirements.
In downlink, each TFAx receives an optical signal from the Master Unit, performs an
optical-to-RF conversion, and transmits the resulting signal to the antenna ports.
In uplink, it receives an RF signal from the remote antennas, provides an RF-to-
optical conversion, and conveys the converted signal to the Master Unit through
optical fibers.
The ION-B Remote Units are available both with power supply 90÷264 Vac and with
power supply -60÷-36 Vdc. Each ION-B Remote Unit is provided with a suitable
internal or external power adapter.
Last, each ION-B Remote Unit has a wideband auxiliary channel, which can be
exploited for dedicated RF distribution through external boosters.

3.3. THE ION-B MASTER UNIT
The ION-B Master Unit is a widely-flexible system. Its modular feature allows it to be
developed both for simple installation-friendly, unobtrusive applications to complex
installations, involving a virtually unlimited number of subracks, and distributed
through several floors of a building or through a 20km distance.
The following text presents a brief overview of the components of these units.
The TPRF31 Fast MiniRack is a 19” x 1HE fast-MiniRack housing 2 slots: it can
therefore accommodate 2 of the single-slots (7TE x 4HE) ION-B cards presented in
the following. Thanks to its turnable brackets, the TPRF31 is suitable both for wall
and rack-mounting, and can therefore be used both as a stand-alone unit (for simple
ION-B installations) and as an integration of a bigger and more complex ION-B
system.
Figure 3-7 TPRF32 Minirack
The TPRN sub-rack is a 19”x 4HE subrack with 12 slots, each one sized 7TE x 4HE.
As each ION-B module takes up one or two slots, each Master Unit can host up to 12
modules, depending on the design configuration and requirements.

The Master Optical TRX (TFLN or
TFLNW): in downlink, it provides an RF-
to-optical conversion of the signal coming
from the BTS, and transmits it to 4 optical
outputs, so as to feed 4 TFAx (TFLNW: 2
TFAH-EU). In uplink, it provides optical-
to-RF conversion for 4 optical signals
coming from the RUs, and it combines
them into a single RF output, while
providing automatic gain control in order
to balance the fibre losses.
Module dimensions:
Width = 7TE, Height = 4HE

splitters/combiners which can be used in
different situations, such as:
To connect a BTS with several master
optical TRXs. In uplink, the TLCNx-W
combines RF signals which come from
different master optical TRXs into a
common RF signal entering the BTS.
In downlink, the TLCNx-W splits the
composite RF signal which comes
from the BTS into more RF ports,
entering different master optical TRXs.
To connect several BTSs to a master
unit. In downlink, the TLCNx-W
combines the RF signals coming from
different BTSs into a common RF
signal, entering the master unit. In
uplink, the TLCNx-W splits the

4.1. THE MAIN TASKS OF THE TFAX REMOTE UNIT
Downlink (DL):
• Optical-to-RF conversion of the input optical signal
• Automatic Gain Control (AGC) of each converted signal in order to compensate
optical losses
• RF amplification: the converted RF signal is boosted in order to maintain a good
signal-to-noise ratio
• RF filtering: a proper filter rejects the spurious emissions
• RF duplexing and splitting: the boosted RF signal is conveyed to one or two
antenna ports according to the different versions
Uplink (UL):
• RF amplification: a low noise amplifier boosts the signal received from antennas
in order to maintain a good signal-to-noise ratio
• RF filtering: the boosted signal is cleaned of the spurious emissions
• Automatic Level Control (ALC): the RF signal level is adjusted according to
blocking requirements
• RF-to-optical conversion of the signal, which is finally conveyed to the output
optical port

4.3. WARNINGS (TO BE READ BEFORE REMOTE UNITS ARE INSTALLED)
The warnings listed below refer to all RUs. Please read them carefully before starting
the installation.
4.3.1. Dealing with optical output ports
TFAx RUs contain semiconductor lasers. Invisible laser beams may be emitted from
the optical output ports. Do not look towards the optical ports while equipment is
switched on.
4.3.2. Choosing a Proper Installation Site for the RU
• TFAx RUs have to be installed as close as possible to the radiating antennas,
in order to minimize coaxial cable length, thus reducing downlink power loss
and uplink noise figures.
• When positioning the TFAx RU, be sure to place related antennas in such a
way as to minimize the minimum coupling loss (MCL), in order to avoid
blocking.
• The TFAx RU is designed to be fastened to walls, ceilings, or other flat
surfaces (TKA installation kits are available, they provide a protective cover for
the TFAx Remote Unit, while making installation easier and faster).
• It is advisable mounting TFAx RU with optical connectors downwards to safe
the optical connectors from improper dirt.
4.3.3. Handling Optical Connections
• When inserting an optical connector, take care to handle it in a way that the
optical fibre is not damaged. Optical fibres have to be single-mode (SM)
9.5/125μm.
• Typically, ION-B equipment is provided with SC-APC optical connectors (other
connectors are provided upon request). Inserting any other connectors will
result in severe damage.
• Do not force or stretch the fibre pigtail with curvature radius of less than 5cm.
See Figure 4-7 Wrong handling of optical connections with ION-B RUs and
Figure 4-8 Correct handling of optical connections with ION-B RUs for optimal
fibre cabling.
• Remove the adapter caps only just before making connections. Do not leave
any SC-APC adapters open, as they attract dirt. Unused optical connectors
must always be covered with their caps.
• Do not touch the connector tip. Clean it with suitable material before inserting
each connector into its sleeve. If connector tips require cleaning, use only pure
ethyl alcohol.

connections with ION-B RUs Figure 4-8 Correct handling of optical
connections with ION-B RUs
Figure 4-9 Splice box open/closed
4.3.4. Antenna Connections - Connectors
For mounting the cable connectors, it is recommended to refer to the corresponding
documentation of the connector manufacturer. The bending radius of the cables must
remain within the given specifications.
For the selection of RF cables, it should be considered that, on the one hand, a cable
with higher loss is less expensive but, on the other hand, it impairs performance.
Notice: Use an appropriate torque wrench for the coupling torques:
- for N-type connectors (2 N-m / 20 in lb) with 13/16 in opening,
e. g. item no. 244379 available from the CommScope e-catalog
- for 7/16 DIN-type (25 N-m / 19 ft lb) with 1 ¼ in opening,
e. g. item no. 244377 available from the CommScope e-catalog
- for 4.3-10 type connectors (5 N-m, 44 in lb) with 22 mm (7/8) in
opening
Do NOT use your hands or any other tool (e.g. a pair of pliers). This might
cause damage to the connector and lead to a malfunction of the
Extension Unit.
User’s Manual for ION-B Systems
Page 38 ION-B User Manual (MN024-15)_n_20150730.docx
Attention: To minimize passive inter-modulation (PIM) distortion, attention has to be
paid to the physical condition of the connector junctions:
Do not use connectors that show signs of corrosion on the metal surface.
Prevent the ingress of water or dirt into the connector.
Use protective caps for the connectors when not mounted.
Before mounting clean the connectors with dry compressed air.
Before mounting clean the mating surfaces of the connector with a lint-free
alcohol-drenched cloth on a wooden or non-metallic item.
Attach and torque the connectors properly.
Avoid metallic abrasion when mounting the connectors by only screwing the
connecting nut, but not turning the whole connector.
Use a torque wrench to fasten the connector, see above.
Clean the protective caps before mounting for antenna cable replacement.

4.3.7. Correct Positioning of the Remote Unit and its Power Supply
• Under no circumstances should any component be affected by the heat
created by any other one. The RU and its external power supply should be
mounted so as to avoid reciprocal heating. Side-by-side configuration is
suggested (see Figure 4-10 90/264 VAC power supply, case B and Figure
4-11 -48 VDC power supply, case B).
• RUs are provided with cooling fins which allow the optimization of heat
dissipation. To ensure proper operation the mounting environment should
allow for the necessary air flow.
• It is strongly recommended not to mount the external power supply on a
horizontal surface because this position does not allow heat dissipation.
External power supplies must be mounted on vertical surfaces.
• In order to assure proper heat dissipation, external power supplies must be
mounted in a vertical position with the power socket downwards (examples for
proper mounting to ensure proper heat dissipation are shown in Figure 4-10
90/264 VAC power supply, case B and Figure 4-11 -48 VDC power supply,
case B).
Figure 4-10 90/264 VAC power supply, case
B Figure 4-11 -48 VDC power supply, case B
Note that the RU and its power supply adapter are mounted side-by-side, and the
power supply adapter has the socket downwards.
4.3.8. Power Supply
The TFAx RU are provided with different types of TPSN external power supplies,
available either for universal mains (90 to 264 Vac) or for negative supply (-60 to -36
Vdc). TPSN external power supplies provide the RUs with either +5Vdc power (by
means of a 3-pole connector, or with +28Vdc/+32Vdc power by means of a shielded
circular connector. Different power ranges are available, see in table 4-1 Remote Unit
Reference Table.

4.3.10. Automatic Gain Control (AGC)
Each RU is provided with an AGC system, which is able to compensate optical
losses when these are estimated to be <3 dB. In case optical
losses are >3.5dB, the LMT application and the ION-B
supervision unit will display a “Warning” alarm: the whole
system still works, but AGC is near to its borderline levels. The
red LED switches on when the estimated optical losses are >4.5
dB; the AGC is no longer able to compensate these losses. As
shown in the previous table, the red LED switches on to indicate
any major failures.

4.10.7.5. Antenna Connection
The Remote Unit has one N-type antenna connector(s). For mounting the cable
connector, it is recommended to refer to the corresponding documentation of the
connector manufacturer. The bending radius of the antenna cables must remain
within the given specifications.
The selection of cable and antenna is an important consideration. On the one hand, a
cable with higher loss is less expensive but, on the other hand, it impairs
performance.
Notice: Use an appropriate torque wrench for the coupling torque of N-type
connectors (2 N-m / 1.5 ft lb with 13/16 in opening to tighten the N-type antenna
connectors. For example, use torque wrench of item no. 244379 available from
the CommScope e-catalog. Do NOT use your hands or any other tool (e.g. a pair
of pliers)! This might cause damage to the connector and lead to a malfunction of
the Remote Unit.
Notice:To minimize passive inter-modulation (PIM) distortion, attention must be paid
to the physical condition of the connector junctions. Do not use connectors that
show signs of corrosion on the metal surface. Prevent the ingress of water into
the connector. Attach and torque the connectors properly.
1. Route the antenna cable from the antenna or splitter to the base of the RU.
2. Cut the cable to length and terminate the cable with an N-type male
connector.
3. Remove the red plastic protective cover from the N-type female connector.

Fiber-System Installation:
Fiber-cable connectors have to be of the same type (LC/APC) as the connectors
used for the unit. The fiber-optic cables are connected to the optical transceiver.
Notice: Angled connectors are not compatible with straight optical connectors; non-
compatibility of connectors will result in permanent damage to both connectors.
Before connecting the fiber cables, follow the procedure below to ensure optimized
performance. It is important for these procedures to be carried out with care:
Remove fiber-optic protective caps just before making the fiber connections.
Do not leave any LC/APC connectors open as they may attract dirt. Unused
optical connectors must always be covered by their caps.
Do not bend the fiber-optic cable in a tight radius (< 5 cm) as this may cause
damage to the cable and interrupt transmission.
Using high-grade alcohol and lint-free cotton cleaning swabs, clean the end of
the fiber-optic cable that will be inserted in the optical connectors on the donor
interface box. Use a fiber end-face inspection tool to scan both, the class fiber
and its surrounding area.
Check for dirt on the cladding, chips/pits, dirt on the ferrule, and scratches.
Connect the fiber-optic cables by inserting the cable end into the laser
receptacle.
Do not use any index-matching gels or fluids of any kind in these connectors.
Gels are intended for laboratory use and attract dirt in the field.
Note: Care should be taken when connecting and disconnecting fiber-
optic cables - use the connector housing to plug or unplug a fiber.
Scratches and dust significantly affect system performance and
may permanently damage the connector. Always use protective
caps on fiber-optic connectors not in use.
Cleaning Procedure for Fiber-Optical Components:
Any contamination in the fiber connection results in additional optical transmission
loss which could cause whole system failure. It is thus recommended that every fiber
connector be inspected and cleaned prior to mating.
The goal is to eliminate any dust or contamination and to provide a clean
environment for the fiber-optic connection.
User’s Manual for ION-B Systems
Page 98 ION-B User Manual (MN024-15)_n_20150730.docx
When you clean fiber components, always complete the following steps carefully:
Caution: Laser radiation. Risk of eye injury in operation. Do not stare into the
beam; do not view it directly or with optical instruments.
1. Turn off the ION-U system (laser sources) before you inspect fiber connectors.
2. Check the connectors or adapters with a fiberscope before cleaning.
3. If the connector is dirty, clean it with a lint-free wipe (dry cleaning).
4. Inspect the connector.
5. If the connector is still dirty, repeat the dry cleaning technique.
6. Inspect the connector.
7. If the connector is still dirty, clean it with 99% isopropyl alcohol (wet cleaning)
followed immediately with a dry clean in order to ensure no residue is left on
the surface.
8. Repeat steps 5 through 7 until surface is clean.

4.11. REMOTE UNIT START-UP
Before switching on the Remote Unit, make sure that:
• the modules hosted in the Master Unit have been connected each other with RF
jumpers, according to the system design
• every TFLN master optical TRX has been connected to its Remote Units
• each Remote Unit has been connected to its coverage antennas
Note: For a correct system start-up, all Remote Units have to be switched
on before the Master Unit.
Once the Remote Unit has been switched on, its behaviour could be checked by
looking at the control LEDs. When the system starts-up, their status can be
summarized by the following steps:
1. When the Remote Unit is turned on, both the LEDs turn on for a couple of
seconds.
2. After that, the unit green LED remains on (thus indicating proper power supply),
while the red LED switches off as soon as the TFLN Master optical TRX is
turned on (meaning that DL optical power is OK and no alarms are present).
3. Once the TFLN Master optical TRX has been switched on, if the red LED
remains on, please refer to the troubleshooting section.
4. After being switched on the RU in order to be recognized by the supervision
management system the corresponding TFLN Master optical TRX must carry
out the discovery phase (please refer to the Supervision System Manual for
more details). During this phase (which lasts up to maximally four minutes
depending on the system complexity) the TFLN LED blinks. Do not
connect/disconnect any cables or pieces of equipment during the discovery
phase! This may result in the identification failure of the RU.
Note: In case discovery does not start automatically, check through either
the LMT or the Remote Supervision if the Remote Unit / discovery
has been disabled (refer to LMT or Remote Supervision System
manuals for further information).

4.13. TROUBLESHOOTING
4.13.1. List of All Alarms
Errors are indicated by LEDs on the TFAx front panel, as well as by LMT or the
Supervision System (running on the remote supervision unit). Both the LMT and the
Supervision System can provide complete information about the cause of the alarm.
As a consequence, troubleshooting is faster if failure detection is carried out directly
through either the LMT or the Supervision System.
ION-B modules are designed to exchange information, meaning that each RU can
receive failure notifications from its external equipment through alarm connections.
Moreover, the TFAx constantly monitors the optical signal received from its TFLN unit
to control optical losses.
The following table shows a brief description of the possible alarms related to a RU,
with reference to the corresponding alerted LEDs and to the actions to be carried out
in case of a fault. Remote units can have a sub-set of the below alarms.

As the table shows, minor alarms (low priority alarms) are indicated only by either the
LMT or the Supervision System, and not through LEDs. Minor alarms detect critical
situations which should be checked and tested in order to avoid future possible
system faults.
The troubleshooting procedures are described in the following chapter and shown in
Figure 4-101 Troubleshooting overview
4.13.2. Quick Troubleshooting
If the red LED is ON, please follow these steps:
1. Refer to Alarm Relay-Contact Troubleshooting section in order to discover
whether or not the alarm is a result of external equipment failure.
2. If alarm-contact troubleshooting has not cleared any failures, clean the optical
connectors.
3. If the problem still persists, refer to section to see if the optical cables or
connections have any problems along the DL path.
4. If none of the previous actions served to switch off the LED, replace the unit with
a new one or contact for assistance.
4.13.3. Alarm Relay-Contact Troubleshooting
This procedure should be considered if at least one TFAx alarm-contact is connected
to any external equipment. If not, return to main troubleshooting procedure.
These steps aim to detect any failure inside external equipment or alarm-contact
ports. If the alarm-contacts troubleshooting cannot clear any equipment malfunctions
or port failures, then return to the main troubleshooting procedure.
For any alarm-contact that is connected to external equipment, follow these steps:
1. Disconnect it, and check the TFAx LED status after the disconnection.
2. If the red LED has switched off, any external equipment that is connected to the
alarm-contact port is probably faulty. Please test it.
3. If the TFAx red LED still remains on after the disconnection, measure the
voltage between the terminals of the alarm-contact port.
a) If the terminals are electrically closed, the alarm-contact port is faulty.
Contact the manufacturer for assistance.
b) If the terminals are open, this means neither the analysis of the present
alarm-contact nor the one of its external equipment has revealed failures.
Re-connect the present alarm-contact port to its external equipment. If the
TFAx has any other unchecked alarm-contacts connected to external
equipment, apply the whole procedure (i.e. steps 1-3) to this port.
User’s Manual for ION-B Systems
Page 114 ION-B User Manual (MN024-15)_n_20150730.docx
4.13.4. Fibre-Optic DL Troubleshooting
1. Check to see if there are any points in which fibres are experiencing a short
radius of curvature. In these cases, rearrange the optical path in order to avoid
sharp bends (if necessary, replace the optical cable with a longer one).
2. Check to see if SC-APC connectors are properly installed at both fibre ends. In
case they are not, re-plug the SC-APC connectors to adapters.
3. Disconnect the optical fibre and clean it at both ends, then clean the SC-APC
ports on both the TFLN and the RU. Re-connect the fibre to relevant ports after
cleaning.
4. Disconnect the optical SC-APC connector from the Remote Unit’s DL port, and
measure the output power P
OUT
(DL) at the corresponding fibre end. Then, go to
the TFLN side, disconnect the optical SC-APC connector from the TFLN DL port
and measure the input power P
IN
(DL) coming out of the TFLN DL port. Calculate
the DL fibre attenuation ADL as ADL [dB] = P
IN
(DL) – P
OUT
(DL):
a) If ADL > 4dB, then there are problems with the fibre optic cable. Replace it
with a new one.
b) If ADL < 4dB, the troubleshooting procedure has not identified the problem.
Refer to the Supervision System or contact assistance.

5. TFBX BOOSTER
5.1. THE MAIN TASKS OF THE TFBX BOOSTER
Downlink (DL):
• RF output power adjustment: to compensate the gain variation of the auxiliary
channel
• RF amplification: RF signal are boosted in order to maintain a good signal-to-
noise ratio
• RF filtering: a proper filter rejects the spurious emissions
• RF splitting: the boosted RF signal is conveyed to two antenna ports
Uplink (UL):
• Automatic Level Control (ALC): the RF signal level is adjusted according to
blocking requirements
• RF amplification: a low noise amplifier boosts the signal received from antennas
in order to maintain a good signal-to-noise ratio
• RF filtering: the boosted signal is cleaned of the spurious emissions

5.3. WARNINGS (TO BE READ BEFORE BOOSTERS ARE INSTALLED)
The warnings listed below refer to all boosters. Please read them carefully before
starting the installation.
5.3.1. Choosing a Proper Installation Site for the booster
• TFBx booster have to be installed as close as possible to the Remote Unit and
to the radiating antennas, in order to minimize coaxial cable length, thus
reducing downlink power loss and uplink noise figures.
• When positioning the TFBx booster, be sure to place related antennas in such
a way as to minimize the minimum coupling loss (MCL), in order to avoid
blocking.
• The TFBx booster is designed to be fastened to walls, ceilings, or other flat
surfaces (TKA installation kits are available; they provide a protective cover for
the TFBx boosters, while making installation easier and faster).
5.3.2. Correct Positioning of the Booster and its Power Supply
• Under no circumstances should any component be affected by the heat
created by any other one. The booster and its external power supply should be
mounted so as to avoid reciprocal heating. Side-by-side configuration is
suggested.
• Boosters are provided with cooling fins which allow the optimization of heat
dissipation. To ensure proper operation the mounting environment should
allow for the necessary air flow.
• It is strongly recommended not to mount the external power supply on a
horizontal surface because this position does not allow heat dissipation.
External power supplies must be mounted on vertical surfaces.
• In order to assure proper heat dissipation, external power supplies must be
mounted in a vertical position with the power socket downwards.
5.3.3. Power Supply
The TFBx boosters are provided with different types of TPSN external power
supplies (TFBH: internal power supply), available either for universal mains (90 to
264 Vac) or for negative supply (-60 to -36 Vdc). Different power ranges are
available, see table 5-1 Booster Reference Table.

antennas. RF antenna ports are duplexed N-female connectors. These RF
ports can be connected to the antennas either directly (i.e. through RF jumper
cables) or through splitters, thus allowing more antennas to be fed. Unused
RF ports have to be terminated with a 50 Ω load.
They can be enabled/disabled through the dip-switch
• 2 RF ports (if applicable), accepting the Remote Unit antenna port as input
and allowing internal combination of the signals of the Remote Unit to the
booster antenna ports
• 1 RF auxiliary input and 1 RF auxiliary output (designed to receive and
transmit signals to the Remote Unit). Auxiliary input and output ports are SMA-
female connectors.
Dip switch
The case B booster is provided with a dip-switch which allows to enable/disable the
second antenna port. In case the antenna port 2 is enabled, relevant green LED is
switched on.
Alarm Relay Outputs
The TFBx is provided with two alarm relay outputs which can be cabled and
connected to the Remote Unit’s alarm relay inputs. This way, the alarm information of
the booster pass to the Remote Unit itself and are signalled through the red LED of
the TFAx and displayed in the supervision system.
Visual Alarms
Three control LEDs are provided on the TFBx case B front side. The left green LED
indicates the power supply status and the antenna 1 enabled, while the red LED
indicates any major booster failures (please refer to the respective troubleshooting
section). The second green LED, on the right, indicates that the antenna 2 has been

5.7. TFBX BOOSTER START-UP
Before the TFBx booster is switched on, make sure that:
• the modules hosted in the Master Unit have been connected to each other with
RF jumpers, according to the system design
• each TFLN Master optical TRX has been connected to its RU
• each booster has been connected to its Remote Unit (both RF and RS232 if
applicable)
• each booster and Remote Unit has been connected to its coverage antennas
For a correct system start-up, all the RUs and boosters have to be switched on prior
to the Master Unit.
Once the TFBx has been switched on, its behaviour can be summarized as per the
following indicators:
1. When the booster is turned on, both LEDs turn on for a couple of seconds.
2. After that, the unit’s green LED remains on (thus indicating proper power
supply), while the red LED switches off.
3. If the booster is connected to the Remote Unit through the RS232 port, once the
booster is switched on the red led of the Remote Unit blinks for a couple of
seconds until the Remote Units gets all the information from the booster about
possible band which needs shut down.

6.1.2. TPRN Models
All of the available TPRN subracks are described briefly on the following pages:
6.1.2.1. Passive subrack (TPRN04)
TPRN04 is a passive subrack. It cannot supply power to any inserted module, and
therefore is designed to host passive modules only. It can be useful in a multi-
subrack system, in case the customer decides to put all the active modules in an
active subrack, to be chosen among the following:
6.1.2.2. 220 Vac powered subracks (TPRN14 / TPRN24)
TPRN14 is an active subrack designed to be fed through 220 Vac universal mains.
Both the connector for the 220 Vac power supply and the communication ports are
placed on the rear of subrack. The 220 Vac power supply is not redundant (ie, no
spare adapter is provided).
TPRN24 is an active subrack designed to be fed through 220 Vac universal mains.
Both the connector for the 220 Vac power supply and the communication ports are
placed on the rear of subrack, and the 220 Vac power supply is redundant: i.e., a
spare adapter guarantees the correct system operations even if the main 220Vac
adapter has a breakdown.
6.1.2.3. -48Vdc powered subrack (TPRN34)
TPRN34 is an active subrack designed to be fed through a –48 Vdc negative supply.
Both the connector for the -48Vdc power supply and the communication ports are
placed on the rear of the subrack.

6.1.3. TPRN Power Supply
All the TPRN models refer to one of the following power supplies:
Universal mains
(85 to 265Vac, 50/60Hz).
This connector is mounted on the TPRN back
panel, both for the redundant version and the
simple one. A ground terminal and a couple of
fuses are also included. Fuses must be
replaced in case of failure (if it happens, the
failure is detected by the Supervision System).
Figure 6-3 85 to 265Vac inlet
-48 Vdc
(-72 to -36 Vdc)
This connector is mounted on the back panel of
the TPRN.
A fuse is provided underneath the -48 Vdc
connector, and must be replaced in case of
failure (if it happens, the failure is detected by
the Supervision System).
Figure 6-4 -48Vdc inlet
Whichever power supply is chosen (85 to 265
Vac or -72 to -36 Vdc) an additional external
ground connector is provided on the rear of the
TPRN.
The external power supply (220Vac or -48Vdc)
is converted to a +12Vdc voltage, feeding the
active modules inserted into the TPRN.

6.1.4. TPRN Ports
The TPRN subrack is provided with a set of I/0 ports which allows the connection to
any external device.
6.1.4.1. RS232 serial port
The RS232 serial port can be used to connect the TPRN subrack to the remote
supervision unit or to a laptop running LMT software. Please note that a standard
RS232 cable is needed.

The connection baud rate can be set to 9600bps or 19200bps, by properly setting the
dip-switch 5 standing on the interior TPRN backplane (Figure 6-6 Dip-switches on the
TPRN backplane). The baud rate setting through dip-switch 5 is shown in table 6-1
Setting the RS232 baud rate through the dip-switch 5.
Whichever baud rate you choose through dip-switch 5, remember that:
• the same RS232 connection speed must be set up on the remote supervision
unit
• the baud rate which is selected through the dip-switch 5 sets the connection
speed for both the RS232 port and the RS485 port as the TPRN uses both
ports with the same rate.
6.1.4.2. RS485 port
The RS485 port consists of two RJ45 connectors, which can both work as input or
output ports towards a RS485 bus.
This RS485 bus has to be used in order to connect a multi subrack system to the
remote supervision unit. In this case:
• the TPRN subracks have to be connected to one another via RS485 bus in a
daisy chain;
• In order to monitor the whole system, the remote supervision unit has to be
connected to one of the TPRN subracks through RS232 port.
Before connecting the TPRN subracks belonging to a multi-subrack system,
remember to assign an exclusive binary address to each one. This is essential in
order to allow the Supervision System recognize the different master units without
any conflicts.
The binary address assignment can be done through dip-switches 1,2,3,4, which are
on the interior TPRN backplane (see Figure 6-6 Dip-switches on the TPRN
backplane). A list of correspondences between the addresses and the dip-switches is
provided in table 6-2 Dip-switches address settings: simply note that dip-switch 1 is
the least significant binary digit, while dip-switch 4 is the most significant one.
The baud rate of the RS485 ports is the same as the RS232 port as per the dip-
switch 5 setting.
Whichever baud rate you choose, remember that:
• the same RS485 connection speed has to be set up on for the entire
connected device (TPRN subracks or TSUN remote supervision unit);
• the baud-rate which is selected through the dip-switch 5 sets the connection
speed for both the RS485 port and the RS232 port.

6.1.6. Warnings - recommended when designing or installing
6.1.6.1. Providing correct heat dissipation
For correct use of the TPRN subrack, it is important to verify that:
• the system is designed for no more than 8 TFLNs inside a TPRN subrack. This
guarantees proper heating dissipation for the system. In case you want to
install more than 8, it is important to provide the subrack with a proper
ventilation system;
• active and passive modules should be alternated as much as possible inside
the TPRN subrack avoiding too many active cards being inserted close
together;
• in case the system consists of more than one TPRN subrack, a minimum
distance of 1 HU has to be kept between nearby TPRN subracks to ensure
proper heat dissipation. The rack containing the TPRN subracks has to be
large enough to guarantee this correct distance between master units.
6.1.6.2. Minimizing equipment costs
In order to reduce the cost of ION-B equipment, a multi-subrack system should be
designed according to the following guidelines:
• a passive subrack (TPRN04) may be used to house only passive modules;
• an active subrack (TPRN14, TPRN24, TPRN34) may be used to sustain all the
active modules, and some of the passive ones (as stated above, it is advisable
to alternate active and passive cards in an active subrack).
6.1.6.3. Setting the dip-switches in a multi subrack system
If you are installing a multi-subrack system, remember to assign each subrack an
exclusive binary address, by properly setting dip-switches 1,2,3,4 on the interior
TPRN backplane (see Figure 6-6 Dip-switches on the TPRN backplane and table 6-2
Dip-switches address settings). Dip-switch 5 has to be set on each TPRN subrack in
order to fix the baud rate for the RS485 and RS232 ports. Connecting the TPRNs
through the RS485 port is necessary when supervising the whole multi subrack
system through the remote supervision unit (to be set at the same baud rate).

6.1.8. TPRN Start-up
Before switching on the TPRN subrack, make sure that:
• all necessary modules have been inserted
• the modules have been connected to each other by RF jumpers, according to
what has been planned during the system design
• each TFLN contained in the Master Unit has been connected to its TFAx
Remote Units
• each TFAx Remote Unit has been connected to its coverage antennas
• the remote supervision unit (if present) has been connected or housed to the
Master Unit
• different subracks have been connected to each other via bus RS485 and
each of them has different addresses
• the rack housing the TPRN is large enough to leave a minimum distance of 1
HU between contiguous TPRN subracks
Remember that TFAx Remote Units have to be switched on before the relevant
Master Unit.
Once the TPRN subrack has been switched on, the system behaviour can be
summarized by the following steps:
• About 10sec after the TPRN subrack has been switched on, all TFLN modules
housed in the TPRN itself begin a “discovery” phase in order to identify and
collect status of the connected TFAx Remote Units. While the discovery phase
is working (max. 4min. depending on the system complexity) each of the TFLN
general alarms (i.e., LED “ ”) blink, whereas the other TFLN LEDs go on
showing the detected status. Do not connect/disconnect any cable or piece of
equipment until all TFLN modules have finished the discovery phase. This may
result in failing to identify the TFAx. Regardless, during the discovery phase,
the entire system continues to work correctly as the discovery process aims to
collect information about the TFAx but without affecting basic system
functionalities.
• Once the discovery has finished, the general alarms (i.e. the LED “ ”) on
each TFLN panel stop blinking and switch OFF (provided that the TFLN
master optical TRX is not affected by a general failure).

6.1.9. TPRN Troubleshooting
In case a TPRN subrack shows any problems, a more detailed status and alarm
description is able to be provided through the remote supervision unit.
A complete overview of TPRN alarms is provided in table 6-4 Description of the
alarms of the TPRN subrack.
A power supply degradation occurs in case the +12Vdc power falls below an in
factory set threshold level. In this case, the TPRN automatically switches to standby
mode so that no over-current is able to get through the circuitry of hosted modules,
thus preserving the system’s integrity. Once the power supply has been repaired, the
TPRN needs to be rebooted. In case the TPRN subrack is equipped with a redundant
power supply (TPRN24), a degradation of the +12 Vdc power results in an automatic
switching from main to spare converter. In case a redundant power supply is
degraded, the TPRN automatically turns to stand-by mode. Once the power supply
has been repaired, the TPRN needs to be rebooted.
A I2Cbus alarm occurs when the TPRN subrack is not able to communicate with one
or more of the hosted modules. Each TPRN slot is able to automatically detect the
presence of a module inside the slot. If the module is detected but the TPRN is not
able to communicate with it through the I2Cbus, an alarm is activated.
Note: At commissioning, remember to mask the unused slots through
LMT software (please refer to the relevant manual for more
information) to avoid triggering insignificant alarms.
Before carrying out any troubleshooting procedures, please check the LMT or
Supervision System manuals.

6.2. FAST MINIRACK TPRF31
6.2.1. Major TPRF Features
The TPRF31 is a low-cost minirack (1HU x 19”) which can host 2 ION-B single-slot
cards, such as:
- 2 Master Optical TRX, thus being able to drive up to 8 ION-B Remote Units
- 1 Master Optical TRX (driving up to 4 ION-B Remote Units) and a proper ION-
B card, working as Point-of-Interface (POI) towards the BTS.
External splitting-combining modules are optionally available, thus providing a
complete solution for building simple and low-cost Distributed Antenna Systems.
Its installation-friendly brackets are suitable for both wall mounting and rack-
mounting, thus making the installation of the ION-B Fast MiniRack easy and
unobtrusive.
Thanks to its RS232 / RS485 bus, the TPRF31 Fast MiniRack can be fully integrated
with any additional ION-B MiniRacks or standard racks, and managed through the full
system supervision, using the ION-B standard supervision interface. Lastly, its
external dry contacts and auxiliary inputs allow the Fast MiniRack to collect
information about any external device, thus making it into a fully environment-
embedded device.

6.2.2. On/Off Switch and Power Supply
The TPRF31 Fast MiniRack can be powered from -36 to -72 Vdc. A fuse is provided
underneath the -48 Vdc connector, and must be replaced in case of failure (when it
happens, the Supervision System will detect the failure).

On/Off switches
6.2.3. Reset and Store/Clear Buttons
Figure 6-15 Rear view of the TPRF31 Fast MiniRack: Reset and Store/Clear buttons
Reset
The Reset button, located on the TPRF31 rear side, performs a complete reset of the
Fast MiniRack, and is particularly useful when the MiniRack bus has become blocked
in any way. Compared to the “manual reset” which can be perfomed by switching off
and on the system through the On/Off switch, the Reset button is preferable because
it does not cause any interruption in feeding the TPRF31.
Store/Clear
The Store/Clear button, located on the TPRF31 rear side, carries out a complete
masking of the unused TPRF31 slots and of its TFLN ports. This operation should be
carried out during the initial system installation, after all of the TFLN units which are
hosted by the TPRF31 MiniRack have stopped blinking (i.e., after they have finished
the discovery phase: see the TFLN section of this User Manual for further
clarification).
The Store/Clear operation must also be carried out after any change affecting the
TPRF slot configuration and the used ports on the TFLN transceivers.
When switching on and off the system in any other circumstances, no Store/Clear
operation is normally required.

6.2.5. TPRF31 Ports
The TPRF31 is provided with a series of ports which allow for the connection to any
external device. These different ports are described hereinafter.
6.2.5.1. RS232 Serial Port
The RS232 serial port can be used to connect the TPRF minirack to the remote
supervision unit or to a laptop running LMT software. Please note that a standard
RS232 cable is needed.
The connection baud rate can be set to 9600 bps, 19200 bps, 57600 bps, or 115200
bps by properly setting the dip-switches 6 and 7 on the rear panel of the TPRF31
backplane (Figure 6-17 Dip-switches on the TPRF31 backplane). The baud rate
setting using the dip-switches 6 and 7 is shown in table 6-6 Setting the RS232 baud-
rate through dip-switches 6 and 7.
Baud Rate [bps] Dip-switch 6 Dip-switch 7

ION-B User Manual (MN024-
15)_n_20150730.docx Page 149
Figure 6-17 Dip-switches on the TPRF31 backplane
Whichever baud rate you choose by dip-switches 6 and 7, remember that:
• the same RS232 connection speed must be set up on the remote supervision
unit
• the baud rate which is selected by the dip-switches 6 and 7 set the connection
speed for both the RS232 port and the RS485 port as the TPRN uses both
ports with the same rate
6.2.5.2. RS485 Port
The RS485 port consists of two RJ45 connectors, which can both work as input or
output ports to and from a RS485 bus.
This RS485 bus has to be used in order to connect a multi subrack system to the
remote supervision unit. In this case:
• the TPRF miniracks have to be connected to one another via an RS485 bus in
a chain;
• in order to monitor the entire system, the remote supervision unit has to be
connected to one of the TPRF miniracks via an RS232 port.
Before connecting the TPRF miniracks belonging to a multi-subrack system,
remember to assign an exclusive binary address to each one. This is essential in
order to let the Supervision System recognize the different master units without any
conflict.
The binary address assignment can be done using dip-switches 1, 2, 3, 4, and 5,
which are located at the backplane of the TPRF (see Figure 6-17 Dip-switches on the
TPRF31 backplane). A list of the correspondences between the addresses and the
dip-switches is provided in table 6-7 Dip-switches address settings: simply note that
dip-switch 1 is the least significant binary digit, while dip-switch 5 is the most
significant.
The baud rate of the RS485 ports is the same as the RS232 port as per the dip-
switch 5 setting.
User’s Manual for ION-B Systems
Page 150 ION-B User Manual (MN024-15)_n_20150730.docx
Whichever baud rate you choose, remember that:
• the same RS485 connection speed has to be set up on all connected devices
(TPRF miniracks or TSUN remote supervision unit);
• the baud rate selected by dip-switches 6 and 7 sets the connection speed for
both the RS485 port and the RS232 port.

Dip-switch 8 is used to match the impedance of a terminal TPRF31 node to the
impedance of the transmission line being used. When the TPRF31 is the first or the
last node of a subrack chain, dip-switch 8 can be set to ON if the length of the RS485
cables in the chain is such to cause a significant propagation delay, compared to the
bit width (and therefore to the baud rate previously set).

6.2.6. Warnings - recommended when designing or installing
6.2.6.1. Installation site features
TPRF31 minirack for safety and security scopes, shall be installed on
telecommunication rooms where there is a restricted access permission.
6.2.6.2. Providing correct heat dissipation
For correct use of the TPRF31 subrack, it is important to verify that:
• in case TPRF31 has been mounted in a vertical position (please refer to the
“TPRF31 Installation” section) the power supplying ports (located on the
TPRF31, front side, Figure 6-18 TPRF31 Power supplying ports on TPRF31
front side (a), Connection scheme of the power supply ports (b)) have been
turned upwards.
• in case TPRF31 has been mounted on a rack (please refer to the TPRF31
Installation section), a minimum distance of 1 HE has been kept between
nearby TPRF mini-racks to ensure proper heat dissipation.
6.2.6.3. Setting the dip-switches in a multi subrack system
If you are installing a multi-subrack system, remember to assign each subrack an
exclusive binary address by properly setting dip-switches 1, 2, 3, 4, 5 on the TPRF31
backplane (see Figure 6-17 Dip-switches on the TPRF31 backplane and table 6-7
Dip-switches address settings). Dip-switch 5 has to be set on each TPRF minirack in
order to fix the baud rate for the RS485 and RS232 ports.
Connecting the TPRFs through the RS485 port is necessary when supervising the
whole multi subrack system via the remote supervision unit (to be set at the same
baud rate).
6.2.6.4. Safety
When installing the TPRF31 mini-rack take care of the following safety issues:
• earth protection (screw on the rear panel) has to be provided before
connecting the power supply cables
• an external disconnecting switch, presenting an overcurrent protection of 16 A
max, shall be added
• the on/off switch on the rear panel does not disconnect the power supply to
the Remote Units (front connectors, Figure 6-18 TPRF31 Power supplying
ports on TPRF31 front side (a), Connection scheme of the power supply ports

6.2.8. TPRF31 Start-Up
Before switching on the TPRF31 minirack, make sure that:
• all the expected modules have been inserted
• the modules have been connected to each other by RF jumpers, according to
what has been planned during the system design
• every TFLN contained in the Master Unit has been connected to its TFAx
Remote Units
• each TFAx Remote Unit has been connected to its coverage antennas
• the remote supervision unit (if present) has been connected or housed to the
Master Unit
• different subracks have been connected to each other via an RS485 bus and
each of them have different addresses
• the rack housing the TPRF31 is large enough to leave a minimum distance of
1 HU between contiguous TPRF31 subracks
Remember that TFAx Remote Units should be switched on before relevant Master
Units.
Once the TPRF31 minirack has been switched on, the system behaviour can be
summarized by the following steps:
• About 10sec after the TPRF31 minirack has been switched on, any TFLN
modules housed in the TPRF itself begin a “discovery” phase in order to identify
and collect the status of the connected TFAx Remote Units. While the discovery
phase is proceeding (max. 4minutes depending on the system complexity) each
TFLN general alarm (i.e., LED “ ”) blinks, whereas the other TFLN LEDs go on
showing the detected status.
Do not connect/disconnect any cable or piece of equipment until all TFLN
modules have finished the discovery phase. This may result in failing to identify
the Remote Units. Nevertheless, during the discovery phase, the entire system
continues to work correctly as the discovery process aims to collect information
about the Remote Units without affecting basic system functionalities.
• Once discovery has finished, the general alarms (i.e. the LED “ ”) on each
TFLN panel stop blinking and switch OFF (provided that the TFLN master
optical TRX is not affected by a general failure).

** The “Alarm output” field indicates the number of the External Alarm Output through which the alarm
information is revealed
table 6-10 Description of the alarms of the TPRF31 subrack
Please note that:
• The power supply degradation (Vcc) occurs in case the +12Vdc power falls
below the critical threshold level. In this case, the TPR31 automatically turns to
standby mode so that no over-current is able to get through the circuitry of
hosted modules, thus switching off the active modules and preserving the
system’s integrity. As soon as the power supply voltage is restored to its
standard level, the TPRF31 automatically turns on the active cards again.
Should this not happen, press the Reset button (see Figure 6-15 Rear view of
the TPRF31 Fast MiniRack: Reset and Store/Clear buttons).
• An I2Cbus alarm occurs when the TPRF31 minirack cannot communicate with
one or more hosted modules. Each TPRF31 slot is able to automatically detect
the presence of a module inside the slot. If a module is detected, but the
TPRF31 is not able to communicate with it, the I2Cbus alarm is activated.

9.5/125μm.
• Typically, ION-B equipment is provided with SC-APC optical connectors.
Inserting any other connector will result in severe damages.
• Do not force or stretch the fibre pigtail with a radius of curvature less than 5
cm. See Fig. 19 for optimal fibre cabling.
• Remove adapter caps only just before making connections. Do not leave SC-
APC adapters open, as they attract dust. Unused SC-APC adapters must
always be covered with their caps.
• Do not touch the adapter tip. Clean it thoroughly before inserting each
connector into the sleeve. In case adapter tips need to be cleaned better, use
pure ethyl alcohol

6.3.6.3. Inserting or removing TFLN modules
• Do not remove or insert any TFLN module into TPRN subrack before having
switched off main power supply.
• The TFLN modules must be handled with care, in order to avoid damage to
electrostatic sensitive devices.
• When installing TFLN modules in the subrack, take care to alternate active
and passive cards in order to ensure proper heat dissipation.
• In a multi-subrack system, remember to assign to each subrack a proper
RS485 bus address before installing the modules (please refer to Rack-Based
Master Unit section for further details).

connectors on a TFLN front panel
TFLN Positioning
• In case no ventilation system has been installed, don’t insert more than 8
TFLN modules into the subrack.
• In case more than 8 TFLN modules have to be housed in a TPRN subrack, it’s
advisable to install the TPRN subrack inside a rack with forced ventilation.
• Be careful to meet expected requirements for RF ports. An adjustable
attenuator might be necessary if the power coming from the BTS exceeds the
required levels, to avoid damaging the ION-B circuitry or an increase of
spurious emissions.

6.3.7. TFLN Installation
The TFLN master optical TRX is housed in a TPRN subrack and its dimensions are 7
TE wide and 4HE high. A TFLN module is able to be accommodated in any of these
12 slots.
Note: In case a new TFLN module has to be installed in a still working
Master Unit, switch off the subrack before inserting the plug-in
TFLN module.
Firstly, gently insert the TFLN into one of the 12 available slots, and lock the 4
screws on the front corners.
Then, connect the UL and DL RF cable to the TFLN UL and DL ports, respectively.
Use an appropriate torque wrench to fix these RF cables to DL and UL ports.
Remove the caps from TFLN optical ports and connect the SC-APC fibre optic cables
to the ports.
UL and DL cables coming from the same Remote Unit have to be connected to the
UL and DL ports marked by the same number on the TFLN front panel.
As you switch on the system, carefully refer to the TFLN Start-Up section.
Remember that Remote Units should be switched on before the Master Unit in order
to follow the correct Start-Up procedure.

6.3.8. TFLN Start-Up
Before the Master Unit is switched on, make sure that:
• all necessary modules have been inserted into the Master Unit
• the modules have been connected each other by RF jumpers, according to
what has been planned in the system design
• every TFLN master optical TRX has been connected to the relevant Remote
Units
• each Remote Unit has been connected to its coverage antenna
• the remote supervision unit, if present, has been connected to the Master Unit
• different Master Units are connected to each other via bus RS485
Following this, the Master Unit itself can be turned on, making sure to turn on all the
Remote Units first,
Once the Master Unit has been switched on, the behaviour of the TFLN at system
start-up is able to be summarized with the following steps:
1. When the Master Unit is turned on, all six LEDs on the TFLN front panel
remain lit for a couple of seconds. After that, the green LED remains lit (indicating
proper power supply) while the other LEDs indicate the master optical TRX status,
according to the following table.
Note: If the unused optical ports of the TFLN haven’t been masked
through the LMT yet, corresponding LEDs will be lit. If this is the
case, wait for the end of step 3 (discovery phase) then use the LMT
to mask them (please refer to relevant manual).
2. About 10 seconds after the system has been switched on, the TFLN module
begins a “discovery” phase to identify all connected Remote Units. This operation
serves to collect all necessary information to be provided to the Supervision System.
During the discovery phase, the TFLN general alarm (LED “ “) blinks while the
other LEDs go on showing their previously detected status’. Time dedicated to the
discovery phase could be up to a maximum of 4 min. and depends on system
complexity.
Note: Do not connect/disconnect any cable or any piece of equipment
during the discovery phase. This may result in failing to identify
Remote Units.
Please note that, while the discovery phase is running, the whole system is working
correctly as discovery operations aim only to collect information about Remote Units
without affecting the system functionalities.
Note: In case discovery doesn’t start automatically, check the LMT or the
remote supervision whether it has been disabled (refer to the LMT
or remote Supervision System manuals for further information).
User’s Manual for ION-B Systems
ION-B User Manual (MN024-
15)_n_20150730.docx Page 167
Once the discovery is finished, the TFLN general alarm (LED “ ”) stops blinking and
switches OFF. The power supply LED (green) remains on while LEDs 1, 2, 3 and 4
show either the status of the Remote Units or the quality of the UL connections.
In case some of these LEDs remain on, check if they refer to unused optical ports or
not. In this case, use LMT software to mask it. Otherwise, if they refer to connected
Remote Units and remain on, please refer to the troubleshooting procedures.
6.3.9. Removing a TFLN Module
Switch off the Master Unit power supply, remove the SC-APC optical connectors, and
insert the protection caps into the TFLN optical ports.
Then:
• unscrew the 4 screws and slowly remove the card
• put the removed TFLN card in its safety box
• switch the Master Unit power supply on again, and refer to the TFLN Start-Up
section.
6.3.10. TFLN Troubleshooting
In case a TFLN master optical TRX has any problems, this will be easily revealed
through the LEDs on its front panels, otherwise troubleshooting can be carried out
through the LMT or the Supervision System.
LEDs on the TFLN front panel detect not only failures on the TFLN board itself, but
also reveal malfunctions located on related Remote Units.
The below table reports a brief description of the TFLN alarms, together with a
reference to the corresponding alerted LEDs.
As the table shows, LEDs on the TFLN front panel signal all high priority alarms while
minor alarms, which detect critical situations which should be checked and tested in
order to avoid future possible system faults, are only revealed by the LMT or the
Supervision System.

Each TFLN is provided with an AGC system which
compensates optical losses of <3 dB. TFLN LED
alarms switch on when the estimated optical losses
are >4dB, when the AGC is not able to compensate
these losses any more.
Figure 6-36 AGC thresholds
vs LED alerts
One of LEDs,1, 2, 3 or 4, might turn on not only to indicate a high optical loss
detected by the TFLN, but also to reveal a Remote Unit failure. Understanding the
reason why one of LEDs 1, 2, 3 or 4 is on (a Remote Unit failure, an optical cable
fault or an external equipment malfunction) can be done following the troubleshooting
procedure reported hereinafter.
6.3.10.1. Quick Troubleshooting Procedure
The following procedure is summarized by the flow-chart in Figure 6-37 Flow-chart
describing the quick troubleshooting procedure.
1. If the TFLN general alarm (LED “ “) is on, replace the faulty TFLN master
optical TRX with a new one and contact the manufacturer for assistance.
2. In case one of the LEDs, 1, 2, 3 or 4, is lit, the corresponding TFLN adapter
might be dirty. Try cleaning it using pure ethyl alcohol. If the LED is still lit, go to the
corresponding Remote Unit side and check the red LED on the TFAx warm side:
a. If it is off, the optical cables or the optical connections are supposed to
have some problem on UL path. Refer to Fibre Optic UL
Troubleshooting.
b. If it is on, refer to Remote Unit troubleshooting presented in the previous
Remote Unit section

6.3.10.2. Fibre Optic UL Troubleshooting
The following procedure is summarized by the flow-chart Figure 6-38 Flow-chart
describing the quick troubleshooting procedure.
1. Check if there is any point where the fibre experiences a small radius of
curvature. In this case, rearrange the optical path in order to avoid sharp bends (if
necessary, replace the optical cable with a longer one). If this causes the TFLN red
LED to switch off, troubleshooting has been successful. Otherwise, follow this next
step.
2. Check if the SC-APC connectors are properly installed at both fibre ends (i.e.
TFLN and TFAx ports). If not, fix the SC-SPC connectors better to their relevant
adapters. If this causes the TFLN red LED to switch off, troubleshooting has been
successful. Otherwise, follow this next step.
3. Disconnect the optical fibre and clean it at both fibre ends (i.e. TFLN side and
TFAx side) then reconnect the fibre to relevant ports. In case this causes the TFLN
red LED to switch off, troubleshooting has been successful. Otherwise, follow the
next step.
4. Disconnect the optical SC-APC connector from TFLN UL port, and measure
the output power POUT(UL) at the corresponding fibre end. Then, go to the TFAx
side, disconnect the optical SC-APC connector from TFAx UL port and measure the
input power PIN(UL) coming out of the TFAx UL port.
5. Calculate the UL fibre attenuation AUL as: AUL [dB] = PIN(UL) – POUT(UL)
a. If AUL > 4dB, the fibre optic cable has some problems or the cable path
is too long. Replace it.
b. If AUL < 4dB, then the TFAx Remote Unit could be faulty. Before
replacing it, check the TFAx status on the Supervision System and
contact for assistance

7.4. SAFETY AND PRECAUTIONS DURING INSTALLATION OR
MAINTENANCE
During installation, the following tools and equipment will be needed:
Typical electrician tools:
cross-point screwdriver, scissors, pliers, nippers, drill and bits, screws for fixing
Remote Units to the wall.
Typical equipment:
proper ladder, scaffolding or air platform for installation of Remote Units.
Attention: some modules are electrostatic-sensitive devices;
electrostatic discharges are caused by direct contact or by an electrostatic
field. If a charged body approaches an electrically conducting surface, the
acquired potential is discharged. An equalising current can than flow in the
associated circuitry and generate permanently damaging voltages by
induction.
Note: The human body should be grounded at the same potential as the
component or equipment being handled. A wrist strap creates an
equipotential electrical connection between the object and the
human.
Attention: Do not paint or otherwise coat ION-B equipment.
Attention: Great caution should always be used when installing any
equipment at a height higher than 2 meters. Personnel who are installing
this equipment should be informed about the possible risks and safety
measures when elevated.
Never remove the cover from a TFAx Remote Unit or from a TPRN
subrack when the power supply is ON.
User’s Manual for ION-B Systems
ION-B User Manual (MN024-
15)_n_20150730.docx Page 197
7.5. POWER SUPPLY CONNECTION
Power connection must be carried out following all necessary precautions:
It must be properly made according to due diligence rules (e.g. EN rules, IEC rules,
etc.);
in accordance with the rules for safety against direct or indirect contacts;
in accordance with the rules for safety against over current (short circuit, overloading)
in accordance with the rules for safety against over voltage;
connection is to be carried out by appropriate and competent staff
Note: In North America, this equipment is to be installed in accordance
with the National Electric Code (NEC) ANSI/NFPA 70 and the
Canadian Electric Code (CEC) Part 1, C22.1.
Attention
: Do not remove or insert any module into the TPRN sub-rack without
prior switching the power supply OFF.
Attention
Do not connect the AC power until you have verified that the line voltage is correct.
Do not remove the plastic cover of the external power supply adapter.
User’s Manual for ION-B Systems
Page 198 ION-B User Manual (MN024-15)_n_20150730.docx
7.6. SAFETY AND LASER PRECAUTIONS
The optical transmitter used in the ION-B contains a laser which has a power level
that is not dangerous for health. However it is classified as class 1 equipment (in
accordance with EN60825). It is nevertheless prudent, during the installation phase,
to observe the following rules:
Never look directly inside the optic connector exit of the transmitter when it is
switched on. The wavelength of the laser is not visible to the human eye,
which means that long-term damage will not be immediately known.
When working with the optical connectors, check at each end that both
transmitting lasers are switched off.
7.7. HEALTH AND SAFETY
Please be aware that each country or governmental body has established its own
specific limits for RF exposure, to which the installation of any radiating antenna must
conform. When installing your ION-B system, take care to comply to your local
regulations and guidelines about RF exposure limits.
Antenna installation must conform to the following guidelines to meet FCC and RSS
RF exposure limits, otherwise an environmental evaluation is required.
RSS Canadian standards
To meet RSS Canadian standard the following guidelines have to be taken into
account:
For any situation where multiple carrier signals are present, take care to
reduce the single-carrier output rating at least by 3.5dB, especially when the
output signal is reradiated and can cause interference with adjacent band
users. This power reduction can be achieved by reducing the input power
which enters the TFLN input ports, not through an attenuator at the output of
the ION-B devices.
FCC US standards
To meet FCC US standard the following guidelines have to be taken into account:
To comply with the FCC exposure compliance requirements, the following
antenna installation and device operating conditions must be satisfied: The
antenna(s) used in the system must be installed to maintain at least a 50-cm
separation distance from any person. The highest allowed antenna gain,
including coaxial cable loss, is 11dBi. RF exposure compliance may need to
be addressed at the time of licensing, as required by the responsible FCC
Bureaus(s), including antenna co-locating requirements of 1.1307(b)(3).
User’s Manual for ION-B Systems
ION-B User Manual (MN024-
15)_n_20150730.docx Page 199
7.8. ELECTROMAGNETIC FIELDS AND RF POWER
The ION-B system generates electromagnetic radiation, which can exceed safety
levels in the immediate vicinity of the antenna.
The most widely accepted standards are those developed by the International
Commission on Non-Ionizing Radiation Protection (ICNIRP) and the Institute of
Electrical and Electronics Engineers (IEEE).
Formula for minimum safety distances
The formula for calculating the minimum safety distances uses the specifications of a
particular antenna that could be driven by TFAx.
This equation includes the following factors:
G is the antenna gain (in dB) compared to isotropic radiating antennas;
P is the RF power that is present at the antenna connector (in W);
L is the total loss (in dB) between the TFAx Remote Unit output port and
the antenna input port;
S is the power density in air (in W/m2) maximum allowed. Its values should
be calculated according to the limit exposures to time-variations and
magnetic fields. The reference values are reported in the ICNIRP
guidelines, unless otherwise specified by specific regulations.
(Please note that, if regulations only define the maximum electrical and
magnetic field strengths, the allowed power density is able to be be obtained
by: S= E
2
/377= B
2
·377
where 377 is the characteristic’s impedance of the empty space).
User’s Manual for ION-B Systems
Page 200 ION-B User Manual (MN024-15)_n_20150730.docx
Example 1.
A Medium Power TFAM 18/20P must distribute mobile signals through a directional
antenna, fed by a 2-metre length RG223 cable (no splitters used). The antenna gain
is 7 dB and the ION-B system distributes one GSM 1800 MHz carrier and one UMTS
2100 MHz carrier.
The maximum allowed power density we have to comply with is:
S = 10 W m
-2
(typical ICNIRP reference level for general public exposure to time-varied electric and
magnetic fields).
By reading the relevant notes for the TFAM 18/20P Remote Unit, we know the overall
output power at the antenna port is able to be estimated as follows:
20 dBm ± 2 ( +22 dBm maximum, equivalent to 0.158 W) for the Cellular 850 MHz
band
20 dBm ± 1.5 ( +21.5 dBm maximum, equivalent to 0.141 W) in the PCS 1900
MHz band.
The total output power at the antenna port is therefore P = 0.158 + 0.141 = 0.299
W.
By reading the cable specs, we get that RG223 cable losses can be estimated at
0.55 dB/m. Total losses between the TFAM 18/20P output port and the antenna input
port can therefore be estimated as follows:
L = 0.55 (dB/m) x 2 (m) = 1.1 dB
By replacing the above values of G, L, P, S parameters inside the formula 6.1, we
therefore get the the following minimum safety distance from the antenna:
r
min
= { 10 -· exp [ (7 - 1.1) / 10 ] · 0.299} / (4·π·10) } - exp (1/2) = 0.096 m
Example 2:
A Low Power TFAH85/19 through a directional antenna is used, fed by a 20 -metre
length ½” cable, with a 2-way splitter. The antenna Gain is 7 dB and the ION-B
system distributes one Cellular 850 MHz carrier and one PCS 1900 MHz carrier.
The maximum allowed power density we have to comply with is:
S = 50 W·m2
(typical ICNIRP reference level for occupational exposure to time-varied electric and
magnetic fields)
User’s Manual for ION-B Systems
ION-B User Manual (MN024-
15)_n_20150730.docx Page 201
By reading the ION-B notes, we know that the output power per carrier at the TFAM
antenna port is
30 dBm ± 2 ( +32 dBm maximum, equivalent to 1.202 W) for the Cellular 850 MHz
band
30 dBm ± 2 ( +32 dBm maximum, equivalent to 1.202 W) for the PCS 1900 MHz
band
The ½” cable losses are 0.07 dB/ m in the 900 MHz band, and 0.11 dB/m in the 2100
MHz band.
The splitter insertion losses are 3.5 dB. The total losses between the TFAH85/19
output port and the antenna input ports can therefore be estimated as follows:
L
850MHz
= 0.07 (dB/m) x 20 (m) + 3.5 = 4.9 dB for Cellular 850 MHz signals
L
1900MHz
= 0.10 (dB/m) x 20 (m) + 3.5 = 5.5 dB for PCS 1900 MHz signals
The term “10 exp (G-L/10) P” which appears inside the formula 6.1 should therefore
be calculated seperately for each frequency, and then added in order to calculate the
composite contribution:
P
850MHz, ant
= 10 exp [(7-4.9)/10]· 1.202 = 1.949 W
P
1900MHz, ant
= 10 exp [(7-5.5)/10]· 1.202 = 1.698 W
P
composite
= P
850MHz, ant
+ P
1900MHz,ant
= 3.647 W
By dividing the total power through (4··S) and taking the square root according to the
formula 6.1, we therefore get the following minimum safety distances from the
antenna:

Example 3.
There is a Medium Power TFAM91/18/20 which is connected to an omnidirectional
antenna through a 10-metre length RG223 cable (no splitters used). The antenna
Gain is 7 dB and the ION-B system distributes two GSM900 carriers, two
GSM1800carriers, and one UMTS2100 carrier.
The maximum allowed electrical field strength is:
E = 6 V m
(typical Italian reference level for exposure to time-varied electric and magnetic
fields). The corresponding value of the maximum allowed power density is:
S = E

By reading the relevant notes for the TFAM 91/18/20 Remote Unit, the overall output
power at the TFAM antenna port can be estimated as follows:
20 dBm ± 2 (+22 dBm maximum, equivalent to 0.158 W) for the Cellular 910 MHz:
21 dBm ± 2 ( +23 dBm maximum, equivalent to 0.200 W) for the GSM1800)
26 dBm ± 1 ( +27 dBm maximum, equivalent to 0.501 W) in the UMTS band
The total output power at the antenna port is therefore:
P = 0.158W x 2 + 0.200W + 0.501W = 1.345 W,
By reading the cable specs, we get that RG223 cable losses can be estimated at
0.55 dB/m. Total losses between the TFAM 91/18/20 output port and the antenna
input port can therefore be estimated as follows:
L = 0.55 (dB/m) x 10 (m) = 5.5 dB
By replacing the above values of G, L, P, S parameters inside the formula 6.1, we
therefore get the the following minimum safety distance from the antenna:
r
min
= { 10 - exp [ (7 - 5.5) / 10 ] - 1.345} / (4··0.1) } - exp (1/2) = 1.22 m

8.3. RETURNING EQUIPMENT
Before returning any equipment to the manufacturer for repairation or replacement, the
customer should give prior notice to the manufacturer and ask for the ‘Return Material
Authorisation’ (RMA request).
RMA REQUEST FORM
Company name
Address
Contact person
Invoice number
Delivery note
№ of pieces
Model 1)
Serial Number 1)
Lot1)
Year1)
Description of the failure/ defect
1) Please refer to the serial label
Upon accepting your RMA request, the manufacturer will assign you a unique RMA
code. You will therefore be able to return the equipment to the manufacturer. Please
remember that:
each piece of equipment must be packaged with care before shipment;
a copy of the RMA request form must be included with the returning
equipment, with clear indication of the RMA code you received from the
manufacturer.
The returned pieces are able to be repaired (where possible) or replaced (when no
repairations can be carried out). These operations are performed under warranty
(please see the warranty conditions specified in the sales contract) or out-of-
warranty. In the latter case, we will send you a bill for equipment repairation or
replacement.
When returning the repaired or replaced equipment, the manufacturer will issue a
check report, which will be included in the packaging together with the returned
pieces. The customer will be informed of any corrective actions suggested for quality
assurance.

The previous flow chart contains the following cross references:
• the master unit installation and cabling is described in more detail in the flow
chart (Figure 9-3 Flow-chart describing the Master unit installation and cabling
steps). It follows the flow of actions from the subrack mounting on the cabinet up
to the settings and connections needed in case remote supervision has to be
considered.
An example of system layout at master unit side is presented in figure below for
a configuration consisting in one sector with four TFLN master optical Trxs.
For more details about TSUNx configuration and start-up refer to the Remote
Supervision manual.

• once the whole system has been installed, the attenuation on the base station
interface has to be defined in order to set up the performances. Use the Britetool
Software to calculate the required attenuation values for uplink and downlink.
Refer to the Britetool manual for more information.

• the system start-up is described in more detail in the flow chart (Figure 9-4 Flow-
chart describing the system start-up steps). It follows the flow of actions from the
remote and master unit switch on and discovery up to the system configuration
through LMT Software and/or remote supervision system.
For more details on how to use the LMT and about TSUNx configuration and
start-up refer to their relevant manuals.
