Pre-installation
Before you begin installing your Libra MAX-58 base station and subscriber stations, you
need to take certain issues and conditions into consideration, prior to, and throughout,
the entire installation process. This chapter defines some of the more common
installation concerns.
Start by reviewing the equipment packing lists to ensure that you have all the cables,
connectors, surge protection devices, fasteners, antennas, and any other installation
material you will require to properly install your equipment. You should also visually
check all components for any physical damage.
Throughout this guide, the term “ODU” refers to the Base Station “Out
Door Unit” portion of the Libra MAX-58 system, this includes the Libra
MAX-RBS and the radio portion of the Libra MAX-HD.
If possible, you should connect all necessary cables and power up the radio equipment
to confirm that it has not been damaged during shipping. You can also perform the
units’ initial configuration before they are sent out to the field. This will ensure your
equipment and all interconnecting cables are functioning properly. Refer to chapters 4
and 5 for more information on configuring your Libra MAX-58 equipment for the first
time.
EION provides this document as a general set of guidelines for installing
its Libra MAX-58 equipment. In no way does EION provide any
warranties as to the effectiveness of these guidelines.
Implementation of these guidelines is solely at your discretion. You
must ensure that the equipment is installed and grounded in
accordance with the local electrical and building codes and the codes
of the country of operation. The Libra MAX-58 equipment must be
installed by a certified professional communication installer, familiar
with all necessary local regulations.
1.6 Required Tools

1.7 Site Evaluation
Before you begin the actual installation of you Libra MAX-58 equipment, you need to
make certain that your equipment site is acceptable and has been properly prepared.
Site preparation will depend on whether you will be installing the MAX-HD chassis base
station, MAX-LT ODU, MAX-RBS ODU or a MAX-SS subscriber station.
Libra MAX User Guide
Pre-installation: Site Evaluation
Page 15 of 120
1.8 Base Station Site Considerations
When you are preparing your site for your Libra MAX-58 base station, you will need to
make allowances for both the base station’s Indoor Unit (IDU) and one or more
Outdoor Units (ODU).
1.8.1 Indoor Unit Site Considerations
Your first step should be to review your network plan and make certain that the chosen
site will be able to house all of your network equipment, not just your Libra MAX-58
system. During your site examination, make certain that you have left adequate service
access in both front and back of any cabinets or equipment racks you are installing.
The site environment for your base station’s IDU should be clean, dust-free, and if
possible, climate controlled. If a climate controlled environment is not possible, you
need to make certain that the equipment can be operated within its specified
environmental limits. Ensuring that there is enough room around your cabinets and
racks for proper ventilation will aid in proper operation of the units.
Proximity to the units’ power mains and correct cable length are other issues that need
to be considered when selecting and preparing your equipment site. The physical
location of the base station’s IDU in the site should be as close as possible to the AC or
DC mains in order to minimize cable length. This connection should be made with
appropriate sized cables. The following table provides the appropriate cable lengths for
a DC power source.
DC Power Cable Size - 10 amps 5%
voltage drop
Maximum Cable length between the
equipment and DC distribution
(feet/meters)
14 AWG
22.97/7
12 AWG
10 AWG
The site must also include a properly installed principle ground bar (PGB) that the
equipment cabinet or rack will be connected to. The physical location of your IDU
should also be influenced by its location to the base station’s ODU. It is important that
you locate the IDU as close to where the ODU will be mounted to minimize cable
lengths.
1.8.2 Outdoor Unit Site Considerations
Conversely, when making your decisions about the ODU’s mounting location, you need
to consider issues such as its proximity to the base station’s IDU if needed, cable
lengths between the IDU and the ODU, and so on.
You should first inspect the site to verify that the antenna mounting structure is
suitable for both the antenna and ODU. The ODU needs to be positioned in a location
that allows for easy maintenance access. You also must review routes that the cables
will follow, when connecting the IDU to the ODU.
Libra MAX User Guide
Pre-installation: Base Station Site Considerations
Page 16 of 120
You should review the proposed cabling entrance/exit points for the site’s building;
they must be practical. You must be able to easily drill the holes for cable access and
the cables should be in a location that allows for easy maintenance.
The MAX ODU has a single shielded CAT5/5e cable to connect the ODU to the IDU
sector card or to connect the ODU to the POE inserter. It is important not to exceed
the maximum allowed length of 100 meters for this cable. This Ethernet cable provides
power to the ODU.
1.8.3 Subscriber Station Site Considerations
Preparing the site for your Libra MAX-58 subscriber station or stations is similar to the
site preparation for the base station’s ODU. You should first inspect the proposed site
to verify that the line-of-site and Fresnel Zone clearances can be met.
You also need to verify that the unit mounting structure is suitable for both the
subscriber station, and the subscriber station’s antenna, if a separate antenna is used.
The subscriber station needs to be positioned in a location that allows for easy
maintenance access.
If the subscriber station is to be mounted to a wall, you will need to consider how the
wall’s material will affect your mounting strategies; the wall is made of cinder-block,
wood, concrete, and so on. You will then need to acquire the appropriate mounting
fasteners to fit the wall material.
You must also review routes that the cables will follow, when connecting the subscriber
station to your terminal equipment. Review the proposed cabling entrance/exit points
for the site’s building; they must be practical. You must be able to easily drill the holes
for cable access and the cables should be in a location that allows for easy
maintenance.
The subscriber station’s proximity to your terminal equipment must be considered as
this will affect the cable lengths between your terminal equipment and the subscriber
station unit. Cables must always be connected without exceeding their recommended
bend radius.
1.9 Base Station Power Sources
If your equipment uses AC power, make certain that the power is provided from a
separate, isolated circuit and that you are using a surge protected power source or a
dedicated Uninterruptible Power Supply (UPS). This will aid in protecting your
equipment against power surges, spikes and/or possible lightning damage. Providing
clean, filtered power will also minimize the possibility of system performance
degradation due to RF interference.
If your base station equipment uses DC power, your power should be supplied from the
main station DC power panel, through a dedicated fused output. A fuse of 15 Amps
should be used.
Libra MAX User Guide
Pre-installation: Base Station Power Sources

1.10 Grounding
Grounding your equipment properly is one of the most important operations you will
perform during installation. Equipment grounding is required for both safety and
effective operation of the installed lightning protection devices.
You must ensure that your system is grounded in accordance with your
local electrical codes and safety laws. EION does not provide any
warranties as to the effectiveness of the grounding concepts and
processes described here, they are for your reference only. EION is
not liable for any damage to your equipment or any injuries to you
resulting from improper grounding.
1.10.1 ESD Warning
Before you begin to install your base station and its components, you should ensure
that your equipment will be protected against electrostatic discharge (ESD). This
section lists some guidelines that you should take into account during installation.
•
Proper grounding is extremely important. Make certain that you ground
yourself before you begin working with your equipment. Also try to ensure that
your workspace is static-free and make use of an anti-static wrist or leg straps.
If you do not have access to static protection, ground yourself to your
environment by first touching your finger to a metal surface before touching
your equipment.
•
All electrical components should be moved or stored in an anti-static bag.
Before you remove a component from its anti-static bag, you should first hold
the bag in one hand while touching a metal surface with the other hand, then
perform the same action with the component.
•
Handle electronic components as little as possible and when you do handle
them, hold all parts by their edge.
•
Never slide static-sensitive equipment across any type of surface. Friction can
cause static build-up.
•
Keep any non-conductive material, such as Styrofoam and other plastics, away
from your work area
1.10.2 Outdoor Unit Grounding
When you are installing your outdoor units, you need to follow proper grounding
practices. The proper grounding of outdoor units helps to minimize lightning damage
and dissipate static buildup. In general, grounding is accomplished by installing a single
heavy gauge wire, such as a 6 gauge, copper cable, between the outdoor unit’s
grounding lug and the mounting structure’s grounding point.
The following section sets out some grounding guidelines for you to follow during
installation.
•
It is very important that the grounding system for your outdoor equipment be
installed by a fully qualified, professional installer, and that proper safety
practices are followed in accordance with your local electrical code.
Libra MAX User Guide
Pre-installation: Grounding
Page 18 of 120
•
Locate your grounding point as close to the outdoor unit as possible. It must
be below the unit and must not be inside a building.
•
The grounding point can be located on an unpainted section of a metal tower,
as section of a building’s metal structure or a ground riser per your applicable
local electrical code.
•
When you run the ground cable to the grounding point, make certain that it
follows a direct path and that you avoid sharp bends in the cable.
•
Do not drill holes in tower supports or cross braces to provide a grounding
point.
•
Do not remove any paint on the outdoor unit chassis.
•
Do not secure the ground cable in a bundle with other data, power, or RF
cables.
•
The chassis of the outdoor unit’s power supply must be connected to the frame
or cabinet via a ground strap.
If you are installing more than one outdoor unit and they will be in close proximity to
each other, do not daisy chain the units’ grounds to each other. This means that you
should not connect the ground of one unit to the ground of another unit and finally to
the grounding system, as shown in Figure 0-1 Daisy Chain Configuration.
Figure 0-1 Daisy Chain Configuration
Daisy chaining the grounds of your units will cause problems such as ground loops,
high resistance paths between units, and reduced ability for dealing with lightning.
Instead, you should use a star configuration, as shown in Figure 0-2 Star
Configuration. In this configuration, each outdoor unit’s grounding lug is connected to a
common grounding point that is then connected to the earth ground.
Libra MAX User Guide
Pre-installation: Grounding
Page 19 of 120
Figure 0-2 Star Configuration
1.10.3 Indoor Unit Chassis Ground
The base station’s indoor unit shelf should be grounded to the cabinet or rack through
a grounding strap. This strap needs to be connected from the grounding bolt, located
at the back of the chassis, to the cabinet’s (or rack’s) grounding bar. It is not sufficient
to rely on the mounting screws to ground the chassis to the cabinet.
You must also run the cable to the grounding point in a direct path and avoid sharp
bends.
Do not secure the ground cable in a bundle with other data,
power, or radio frequency cables.
1.11 Lightning Protectors
The use of lightning protectors and surge suppressors is extremely important and,
although your Libra MAX-58 equipment will operate without them, it is highly
recommended that you make use of them. Lightning protectors and surge suppressors
are used to aid in the protection of your outdoor units against lightning damage and
static discharge.
During installation, it is important to note that all lightning protection devices have a
surge (or cable-facing) side and an equipment facing side, as shown in Figure 0-3
Surge Suppressor Sides. The equipment side generally faces the outdoor unit or the
indoor power adapter. The surge side faces the other surge suppressor.
Libra MAX User Guide
Pre-installation: Lightning Protectors
Page 20 of 120
Figure 0-3 Surge Suppressor Sides
1.11.1 Surge Suppression Unit Location
Lightning arrestors and surge protectors should be installed at all input/output points
on the Libra MAX-58 equipment. Additionally, they should be properly grounded by
connecting the body of the arrestor or protector to the grounding system with a heavy
gauge (6 AWG) copper wire. This grounding wire should be as short as possible.
The following figures illustrate the locations where the surge suppressors must be
installed, when cabling both the base station and the subscriber station.

Figure 0-6 Subscriber Station (MAX-SP) Surge Protector Diagram with
External Antenna
When installing surge suppressors between your outdoor unit and the antenna, use
protectors that provide a DC short such as an L-C circuit or one quarter-wave shorting
stub. These protectors should be physically located as close as possible to the ODU,
preferably no further than five (5) feet (1.52 metres). Also, a star configuration should
be used when grounding your surge suppressors.
1.12 Weatherproofing Connectors
One of the most common installation problems is water intrusion, due to improper
weatherproofing. Unfortunately, this activity is often overlooked and can lead to costly
repairs and unnecessary expenses if not completed properly or not performed at all.
Therefore, it is extremely important to properly weatherproof your connectors.
An additional reason for using tape to weatherproof your cable
connections is to prevent the connection loosening, due to
environmental conditions.
One method is to apply two layers of high quality rubber tape to the connectors, then
apply two layers of high quality vinyl electrical tape, such as:
Libra MAX User Guide
Pre-installation: Weatherproofing Connectors
Page 24 of 120
•
Scotch® 130C Linerless Rubber Splicing Tape
•
Scotch® Super 88 Premium Vinyl Electrical Tape
Corrosion is another problem that arises if your cabling system is not properly
weatherproofed. Corrosion can lead to high impedance at contact points, which can
drastically reduce the effectiveness of your lightning protection. To help stop corrosion,
you should use an anti-oxidizing paste on all contacts. When using anti-oxidization
paste, keep the following guidelines in mind:
•
read the instructions and warnings for the selected product
•
lock washers should be used since the anti-oxidization paste acts as a
lubricant
•
use a small amount. A thin film applied to exposed surfaces and on contact
points is adequate
•
do not apply the anti-oxidization paste to the data cable connections on the
outdoor unit. The anti-oxidization paste is conductive and may degrade
performance and damage equipment.
•
using electrical or rubber tape is not recommended for sealing the
grounding connections when anti-oxidization paste is used
•
do not use thread-locking compound on the same bolt or screw as antioxidization paste is used.
1.13 CAT-5 Ethernet Cable Shielding
Using shielded CAT-5 Ethernet cable is very important when installing your BS or SS
ODU, as it will help in reducing data errors caused by nearby interference.
It is also very important that the shield be connected at only one end of the cable, the
end that connects to the indoor unit. This is required to eliminate ground loops caused
by current flowing between the indoor and outdoor units, due to a possible difference
in ground levels. Such currents can damage equipment at either end or introduce noise
that will interfere with the user data traffic on the cable.

1.15 Installing the BS Outdoor Unit
This chapter discusses how to install your Libra MAX-58 Base Station Outdoor Unit
equipment. There are four general tasks that you will need to perform when you install
your Libra MAX-58 subscriber station. They are:
1. configuring your outdoor unit equipment
2. installing your outdoor unit equipment
3. mounting the antenna, if the equipment uses a separate antenna
4. cabling the outdoor unit
Please review the Pre-installation chapter before you begin installing
your equipment.
1.16 Connecting the Ethernet Cable
Before you mount your outdoor unit, either on a pole or a wall you will need to
temporarily connect an Ethernet cable between the unit and your computer’s Ethernet
port. This is to allow you to configure your outdoor unit.
If connecting the unit directly to a laptop or PC, a crossover Ethernet cable is required.
For information on configuring your outdoor unit for the first time, refer to the chapter
Base Station Configuration and Management.
1.17 Mounting Conditions
The two (2) general subscriber station mounting scenarios are:
1. pole mount
2. wall mount
1.18 Pole Mounting
If you are mounting your Base Station Outdoor Unit using an external antenna, you will
not have to concern yourself with the polarization of the antenna. In this instance,
attach the mounting bracket unit anchor to the side of the unit housing as shown in the
figure below.
Figure 0-17 Mounting Bracket Unit Anchor

not tighten the pivot nut and bolt until you have aligned your antenna.
1.20 Wall-mounting the Outdoor unit
1. To mount your outdoor unit to a wall:
1.1. Prepare the wall to hold the mounting bracket. The type of mount you
create will depend upon the type of wall surface and material your wall is
made of. It may be that you only need to drill holes and insert bolt
anchors, or you may have to fabricate a strong mount that will withstand
the unit’s weight, outside temperature change, or other variables. For this
reason, EION requires that you supply your own fastening bolts, lagscrews, or other fastening devices.
1.2. Place the back of the bracket against the wall mount, as shown below.

How you connect your grounding cable to a common earth ground will
depend on how you have prepared the installation site and where the
outdoor unit is installed. For more information on outdoor unit
grounding requirements, refer to the Outdoor Unit Grounding section
of this manual.
1.21 Antenna Mounting Guidelines
It is essential that you properly install your base station's antenna. This ensures that
your system is operating at optimum performance and aids in protecting it against
lightning damage.
To correctly install your antenna, it is very important that you follow your antenna
manufacturer's installation instructions closely. In addition, keep the following
guidelines and practices in mind while performing your installation.
1.21.1 Mounting the Structure
Make certain that the mounting structure (i.e.: pole mount, wall mount, etc.) is
perpendicular to the horizontal, as shown below. This is essential, because the
antenna’s mechanical tilt indicator or indicators rely on using a vertical mounting
surface for its reference point. The degree of vertical accuracy should be checked and,
if necessary, corrected prior to the installation of the antenna. The mounting surface's
vertical angle can be verified using a level or angle indicator.

1.22 Cabling the Base Station
Once you have installed and mounted all of your Libra MAX-58 base station equipment,
you will need to connect all of the cables required to power the units and transmit the
data. This will require that you connect all of the power and data cables to the base
station’s indoor unit, then connect all of the cables between the indoor unit and the
outdoor unit, then finally connect the cables between the outdoor unit and the
antenna.
Libra MAX User Guide
Base Station Installation: Cabling the Base Station
Page 40 of 120
Figure 0-26 Libra MAX-58 Base Station Layout Diagram
A Libra MAX-58 BS ODU can be connected to the Indoor Unit (IDU chassis) in one of
two ways. One way is to connect the ODU directly to the chassis using the PoE cards
with power provided by the 48V power supply. The other method is to connect the BS
ODU to the switch fabric card with power supplied by an External PoE injector. The
following layout diagram shows both of these options. The two different cabling options
are further explained with lightning and surge protection in the diagrams that follow.
The following sections set out the steps that you should follow in order to install the
cables needed by your Libra MAX-58 base station. When you have completed cabling
your Libra MAX-58 cable connections should resemble those shown in the following
drawing.

1.23 Weatherproofing Cable Connections
One task that is extremely important is weatherproofing the connections between your
cable and an outdoor unit or antenna. Not only does this prevent corrosion and keep
water from interfering with the connection, it also aids in keeping the connection tight.
In general, you will weatherproof two types of connection, cable to outdoor unit or
antenna and cable to cable.
1.23.1 Cable to Outdoor Unit Connections
Most antenna or outdoor unit problems are caused by coaxial cable connections that
loosen due to vibration, allowing moisture to penetrate the connector interface. EION
recommends that all outdoor unit to cable connections be weatherproofed using a
procedure similar to the one described below.
Fasten connectors securely together, as shown in below. Ensure the connector and
cables are free of foreign substances such as oil, water, grease, dirt, etc.
Figure 0-29 Secure Connector
Tightly wrap two (2) layers of rubber splicing tape over the connection extending one
(1) inch (2.54 cm) beyond the connectors and overlapping the tape on each turn, as
shown below.

1.23.2 Cable to Cable Connections
Problems that occur in coaxial cable connections are often due to moisture penetration
and corrosion in loose connections, caused by vibration. EION recommends that all
cable to cable connections be weatherproofed using a procedure similar to the one
described below.
Fasten connectors securely together, as shown below. Ensure the connector and cables

Tightly wrap two (2) layers of electrical tape over the rubber splicing tape extending
one (1) inch (2.54 cm) beyond the rubber splicing tape, as shown below.
1.24 Installing a Drip Loop
Another preventative measure that you can perform is to install a drip loop, as shown
in the figure below. Drip loops should be incorporated into the cable before it is
connected to outdoor devices, such as outdoor units, antennas, etc. For example, if
you are installing one of the cables that run between the indoor unit and outdoor unit,
you may want to install a drip loop in the cable immediately before it enters the
building.
Libra MAX User Guide
Base Station Installation: Installing a Drip Loop
Page 45 of 120
Figure 0-34 Cable Drip Loop
Drip loops should be incorporated into a system’s external cabling at any point where a
connection is made. Some examples of where a drip loop should be used are:
•
cable to outdoor unit connection
•
cable to antenna connection
•
cable to cable connection
•
the junction where a cable enters a building or structure
•
a common grounding junction box or bar
1.25 Cabling the Indoor Unit
Your first task in cabling your Libra MAX-58 base station is to connect all of the wires
and cables to your indoor unit. To cable your indoor unit:
Connect the PoE translation card’s power plug to the DC power supply leads, as shown
in the figure on the next page.

1.26 Cabling to the Outdoor Unit
Once you have finished cabling your indoor unit, you will need to run your cables and
connect them to the outdoor unit. To cable your outdoor unit:
Run the Ethernet cable from the inside of your site, through your building wall opening,
to the outside of your building. How the cable will be run will depend on the strategy
you used to create the building opening and, as such, cannot be defined here.
Connect the Ethernet cable to the outdoor unit 8-pin DIN female circular connector, as
shown in the figure below.
Figure 0-38 Connecting the Ethernet Cable to the ODU
Weatherproof the connection, as described above.
1.27 Cabling to the Antenna
To connect the radio frequency cable between the base station’s outdoor unit and the
antenna, perform the following steps:
1. Connect the radio frequency cable to the outdoor unit socket labeled ANT.
2. Weatherproof the cable connection, as outlined on page 44 above.
3. Connect the surge suppressor to the cable, per the manufacturer’s instructions.
Selection of the lightning protector should be of the Non DC Pass as this will
also aid in the prevention of static discharge damaging the equipment or
degrading performance by introducing noise to the receiver portion of the
outdoor unit.
4. Weatherproof the suppressor connection, as outlined on page 44 above.
5. Connect the cable from the surge suppressor to the antenna, per the
manufacturer’s instructions.
6. Weatherproof the suppressor connection, as outlined on page 44 above.
Libra MAX User Guide
Base Station Installation: Cabling to the Outdoor Unit
Page 48 of 120
7. Ground the suppressor to a common earth ground, per the manufacturer's
instructions. RF cable sections (before and after the suppressor) should be kept
as short as possible.
1.28 Connecting the Ethernet Cable
You will need to connect your base station to your network via Ethernet. Connect an
Ethernet cable to your base station to either of the two ports shown shown below. If
you are connecting your base station’s Ethernet port directly to a computer, you will
need to use a cross-over cable for the connection.
Figure 0-39 Connecting an Ethernet Cable to the Sector Card’s Ethernet Port
1.29 Powering on the Base Station
Once all of the equipment has been installed and cabled, you should connect the power
to the base station and power it on to check that all components are operating
correctly.
You can use either AC or DC power for your base station, depending on your needs and
the chassis you choose to use.
1.29.1 AC Power
The AC chassis requires that you use both AC and DC to power the base station chassis
and components. AC is used to power the chassis itself and all of the cards installed in
it, through the built-in power supplies. The DC is used to provide the -48V power to
the outdoor units, through the PoE card or cards.
To plug your base station into an AC mains outlet:
1. Plug the AC power cord into the indoor unit chassis’ AC power socket, as
shown below.
Libra MAX User Guide
Base Station Installation: Connecting the Ethernet Cable
Page 49 of 120
Figure 0-40 AC Power Socket
2. Connect the DC power cord(s) from the DC power supply to the indoor unit
chassis’ DC Power Connectors, shown in Figure 0-40 AC Power Socket.
3. Plug the AC power cord into your power bar or UPS. Make certain that your
power bar or UPS is plugged into the AC wall outlet.
4. Turn on the indoor unit chassis power switch, shown in the above figure. When
the base station is first powered up, it takes roughly four (4) minutes for the
sector card to boot up. You cannot use the sector card until it has booted up
completely.
1.29.2 DC Power
The DC variant of the indoor unit’s chassis does not need any AC power to operate, it
only uses -48V DC power. You will, however, need to run a power jumper from the DC
power distribution panel sockets to the PoE card DC power sockets before you can use
the base station.
To plug your base station into a DC mains outlet:
1. Run a patch cord from each one of the DC power distribution panel sockets to
one of the PoE card DC power sockets, shown in Figure 0-41 DC Power Sockets
below. Make certain that you connect all of the installed PoE cards to the DC
power sockets.
Figure 0-41 DC Power Sockets

1.31 Antenna Mounting Guidelines
It is essential that you properly install your RBS’s antenna. This ensures that your
system is operating at optimum performance and aids in protecting it against lightning
damage.
To correctly install your antenna, it is very important that you follow your antenna
manufacturer's installation instructions closely. In addition, keep the following
guidelines and practices in mind while performing your installation.
1.31.1 Mounting the Structure
Make certain that the mounting structure (i.e.: pole mount, wall mount, etc.) is
perpendicular to the horizontal, as shown below. This is essential, because the
antenna’s mechanical tilt indicator or indicators rely on using a vertical mounting
surface for its reference point. The degree of vertical accuracy should be checked and,
Libra MAX User Guide
Rapid Backhaul System Installation: Antenna Mounting Guidelines Page 59 of 120
if necessary, corrected prior to the installation of the antenna. The mounting surface's
vertical angle can be verified using a level or angle indicator.
Figure 0-11 Vertical Mounting Surface
1.32 Cabling the RBS
Once you have installed and mounted all of your Libra MAX-58 RBS equipment, you will
need to connect all of the cables required to power the units and transmit the data.
This will require that you connect all of the power and data cables to the RBS and
connect the cables between the RBS and the antenna.

1.33 Weatherproofing Cable Connections
One task that is extremely important is weatherproofing the connections between your
cable and an RBS or antenna. Not only does this prevent corrosion and keep water
from interfering with the connection, it also aids in keeping the connection tight.
In general, you will weatherproof two types of connection, cable to RBS unit or antenna
and cable to cable.
Libra MAX User Guide
120
Rapid Backhaul System Installation: Weatherproofing Cable Connections Page 61 of
1.33.1 Cable to RBS Connections
Most antenna or radio problems are caused by coaxial cable connections that loosen
due to vibration, allowing moisture to penetrate the connector interface. EION
recommends that all RBS to cable connections be weatherproofed using a procedure
similar to the one described below.
Fasten connectors securely together, as shown in below. Ensure the connector and
cables are free of foreign substances such as oil, water, grease, dirt, etc.
Figure 0-13 Secure Connector
Tightly wrap two (2) layers of rubber splicing tape over the connection extending one
(1) inch (2.54 cm) beyond the connectors and overlapping the tape on each turn, as
shown below.

1.33.2 Cable to Cable Connections
Problems that occur in coaxial cable connections are often due to moisture penetration
and corrosion in loose connections, caused by vibration. EION recommends that all
cable to cable connections are weatherproofed using a procedure similar to the one
described below.
Fasten connectors securely together, as shown below. Ensure the connector and cables
are free of foreign substances such as oil, water, grease, dirt, etc.

one (1) inch (2.54 cm) beyond the rubber splicing tape, as shown below.
1.34 Installing a Drip Loop
Another preventative measure that you can perform is to install a drip loop, as shown
in the figure below. Drip loops should be incorporated into the cable before it is
connected to outdoor devices, such as outdoor units, RBS, antennas, etc. For example,
if you are installing one of the cables that run indoors from an RBS, you may want to
install a drip loop in the cable immediately before it enters the building.
Figure 0-18 Cable Drip Loop
Drip loops should be incorporated into a system’s external cabling at any point where a
connection is made. Some examples of where a drip loop should be used are:
•
cable RBS connection
•
cable to antenna connection
•
cable to cable connection
•
the junction where a cable enters a building or structure

1.35 Cabling to the RBS
To cable your RBS unit:
Run the Ethernet cable from the inside of your site, through your building wall opening,
to the outside of your building. How the cable will be run will depend on the strategy
you used to create the building opening and, as such, cannot be defined here.
Connect the Ethernet cable to the RBS unit 8-pin DIN female circular connector, as
shown in the figure below.
Figure 0-19 Connecting the Ethernet Cable to the RBS
Weatherproof the connection, as described above.
1.36 Cabling to the Antenna
To connect the radio frequency cable between the RBS unit and the antenna, perform
the following steps:
8. Connect the RF cable for the antenna that is pointing at a subscriber station to
the RBS socket labeled ANT.
9. Connect the RF cable for the antenna that is pointing at a Base Station to the
RBS socket labeled IF.
10. Weatherproof the cable connection, as outlined on page 44 above.
11. Connect the surge suppressor to the cable, per the manufacturer’s instructions.
Selection of the lightning protector should be of the Non DC Pass as this will

1.39 Base Station Configuration (BS)
1.39.1 Basic Configuration
This screen appears after clicking on ‘BS’, then on ‘Configuration’ and then on ‘Basic’. It
allows configuration of the following:
Figure 0-4: Basic Configuration
BS ODU ID – It is a globally unique numeric identifier for the BS ODU and hence the
network. It is 6 bytes (48 bits) in length. This identifier has to be entered in the
subscriber stations for them to communication with this particular BS. By default this is
set as the MAC Address of the BS ODU. The Base Station must be rebooted for
changes to the BS ODU ID to take effect.
NMS Source – It configures whether the NMS and AAA server to be used should be
loaded from the BS ODU itself or a sector card with standalone NMS/AAA server. This
has to be set to BS_ODU for MAX-LT. For MAX-HD it can be set to either BS_ODU or
SECTOR_CARD as needed. The Base Station must be rebooted for changes to the NMS
Source to take effect.
Libra MAX User Guide
Base Station Configuration: Base Station Configuration (BS)
Page 70 of 120
BS ODU MAC Address – It displays the MAC address of the active port of the BS
ODU. This MAC address has to be configured into subscriber stations if you want them
to specifically connect to the particular BS ODU of interest. MAC address is not
configurable by user.
BS ODU IP Address – It is the IP of the active port of the BS ODU. IP address has to
be in the same subnet as the subscriber station. The Base Station must be rebooted for
changes to the BS ODU IP Address to take effect. Note that if the IP Address is
changed, you will need to login using the newly configured IP address.
NOTE: The default BS ODU IP Address is 192.168.1.40
DHCP Enable – Setting it to ‘Enable’ activates a DHCP server in BS ODU so that
subscriber stations associated with it can receive IP address automatically. It is
disabled by default. The Base Station must be rebooted for changes to DHCP to take
effect.
Syslogd – It configures where the log files for the BS ODU are stored. Its value is set
to ‘Local’ by default. The Base Station must be rebooted for changes to the Syslogd to
take effect.
1.39.2 VLAN Configuration
Currently the VLAN setting allows users to configure a management VLAN. This allows
network administrators access to the management GUI over a specified VLAN.
Support of Management VLAN will prevent this and will allow access to the Base Station
only from the specified VLAN (Management VLAN). So, the Base Station can be
accessed and managed only from a system that is in the specified VLAN either on the
Ethernet side of the Base Station or on any of the associated Subscriber Stations
network. The following figure depicts this behavior when a Management VLAN is
specified in the Base Station.
Libra MAX User Guide

1.40 Subscriber Station Association (SS)
This section contains information about the subscriber station(s) associated with the
BS. For a SS to associate with BS, MAC address of the SS has to be listed in the BS
apart from them being on the same RF frequency. Also, at least one QoS for downlink
and uplink has to be defined.
1.40.1 QoS
Quality of Service is a set of service related parameters given by the operator to the
subscriber (customer). It defines all parameters that are described in the IEEE 802.16d
documentation. This section can be accessed by clicking on ‘SS’ and then on ‘QoS’.
Existing QoS can either be edited or deleted.
Upon selecting a different direction, scheduling type or CS specification, the QoS
parameters will also be set to default and relevant set of fields are enabled.
Upon deletion of a PCID, the PCID has to be dissociated with each subscriber station
manually.
Figure 0-17: QoS Main Page
To add a new QoS, click on the link ‘Add New QoS’. The following screen appears. Two
sample QoS have been added by default.
Figure 0-18: Add QoS

After configuring the QoS for downstream, click on ‘Back to QoS List’ on top and then
add another QoS, this time for the downstream.
Figure 0-20: Downstream QoS Configuration for BE
At least one uplink and one downlink classifier need to be defined for
successful communication between the base and subscriber stations.
Number – This should be a unique identifier given manually by the operator for ease
of use.
Service Class Name – A unique class name given to identify the service (DL or UL) &
its capabilities (data rates).
Example: SF__
Direction – It provides the direction of the service flow whether in down-link or uplink. Default is set for Request transmission policy. At least one upstream and one
downstream classifier have to be assigned to a SS.
Libra MAX User Guide
Base Station Configuration: Subscriber Station Association (SS) Page 85 of 120
Service Flow Scheduling Type – The value of this parameter specifies the
scheduling service that shall be enabled for the associated service flow.
CS Specification – Service-specific CS resides on top of the MAC CPS and utilizes, via
the MAC SAP (Service Access Point), the services provided by the MAC CPS (Common
Part Sub layer). Recommended value is ‘Packet, IPv4 over 802.3/Ethernet’.
Traffic Priority – The value of this parameter specifies the priority assigned to a
service flow. Given two service flows identical in all QoS parameters besides priority,
the higher priority service flow should be given lower delay and higher buffering
preference. This field is mandatory for nrtPS. Its default and the minimum value is 0
and the maximum value is 7.
Maximum Sustained Traffic – This parameter defines the peak information rate of
the service. The rate is expressed in bits per second and pertains to the SDUs at the
input to the system. If this parameter is omitted or set to zero, then there is no
explicitly mandated maximum rate. This field specifies only a bound, not a guarantee
that the rate is available. This field is mandatory for BE. Its minimum value is 0 and the
maximum value is 20480000 bps.
Maximum Traffic Burst – This parameter defines the maximum burst size that shall
be accommodated for the service. Since the physical speed of ingress/egress ports, the
air interface, and the backhaul will, in general, be greater than the maximum sustained
traffic rate parameter for a service, this parameter describes the maximum continuous
burst the system should accommodate for the service.
Minimum Reserved Traffic – This parameter specifies the minimum rate reserved
for this service flow and is equal to (SDU Size)*8/(Maximum Latency). The rate is
expressed in bits per second and specifies the minimum amount of data to be
transported on behalf of the service flow when averaged over time. It is disabled by
default.
Min Tolerable Traffic – This parameter specifies the minimum tolerable rate in bits
per second for this service flow. This value should not be higher than the
corresponding Minimum Reserved Traffic Rate value. The difference between these two
values reflects SDUs’ loss rate. It is disabled by default.
Unsolicited Grant Interval – The value of this parameter specifies the nominal
interval in milliseconds between successive data-grant opportunities for this Service
Flow. The maximum unsolicited grant interval field specifies only a bound. It is
applicable to UGS. It is disabled by default. Its minimum value is 0 and maximum value
is 100 ms.
Unsolicited Polling Interval – This parameter defines the maximum nominal interval
in milliseconds between successive polling grants opportunities for a DL and UL service
flow. If this parameter is set to zero, then there is no explicitly mandated unsolicited
grant interval. It is mandatory for Best Effort, nrtPS and rtPS services in Uplink
direction only. Its default and minimum value is 0 ms and maximum value is 5000 ms.
FSN Size – This indicates the size of the FSN for the connection that is being setup. A
value of 0 indicates that FSN is 3-bit long and a value of 1 indicates that FSN is 11-bit
long. It is mandatory for rtPS service. Its default value is set at 11-bit FSN.
Tolerated Jitter – This parameter defines the maximum delay variation (jitter) for the
connection. It is disabled by default. It is mandatory for UGS service. Its minimum
value is 0 ms and the maximum value is 2048 ms.
Libra MAX User Guide
Base Station Configuration: Subscriber Station Association (SS) Page 86 of 120
Maximum Latency – The value of this parameter specifies the maximum latency
between the reception of a packet by the BS or SS on its network interface and the
forwarding of the packet to its RF Interface. It is disabled by default but is mandatory
for rtPS and UGS services. Its minimum value is 0 ms and the maximum value is 2048
ms.
Request Transmission Policy – The value of this parameter provides the capability
to specify certain attributes for the associated service flow. One or more can be chosen
in these parameters. Only a few options are enabled depends on the service type.
Shall not Include CRC in the MAC PDU:
If checked, the service flow shall not include CRC in the MAC PDU.
If unchecked, this feature is on and will request bandwidth using CRC in the MAC PDU
(if CRC in the MAC PDU groups are created).
Shall not use Packing:
If checked, the service flow shall not pack multiple SDUs (or fragments).
If unchecked, this feature is on and will request bandwidth using packing (if packing
groups are created at BS).
Shall not suppress payload headers (PHS):
If checked, the service flow shall not suppress payload headers (CS parameters).
If unchecked, this feature is on and will request bandwidth using suppress payload
headers (if PHS groups are created at BS). PHS is disabled by default.
Shall not Use uplink Piggyback requests with data:
It is applicable to Upstream QoS.
If checked, the service flow shall not piggyback requests with data. Please keep this
checked.
If unchecked, this feature is on and will request bandwidth using uplink piggyback
requests (if Piggyback groups are created at BS)
Default: Piggyback is off.
Shall not Use Fragmentation:
If checked, the service flow shall not fragment data.
If unchecked, the feature is on. The packets can be fragmented and sent to SS on this
service. The number of bits in FSN Size is used as the sequence number of the
fragmented packet.
Shall not Use UL Broadcast-Bandwidth request opportunities:
It is applicable to Upstream QoS.
If checked, service flow shall not request broadcast bandwidth request opportunities.
Please keep this option checked.
Libra MAX User Guide
Base Station Configuration: Subscriber Station Association (SS) Page 87 of 120
If unchecked, the feature is on. This particular service flow will request bandwidth
using uplink broadcast request opportunities. Broadcast bandwidth request is done on
the contention slot.
Shall not use UL multicast bandwidth request opportunities:
It is applicable to Upstream QoS.
If checked, service flow shall not request bandwidth using multicast connection
identifiers.
If unchecked, the feature is switched on. This particular service flow will request
bandwidth using multicast connection identifiers.
1.40.2 SS List
Subscriber stations are added in this section.
MAC Address – This parameter provides MAC address of SS. This is unique for a
particular SS. This is also used as SS ID to identify as SS. In order for the SS to
associate with the BS, correct OFDM MAC address of the SS has to be entered in the SS
list. This MAC address is printed on the label of the SS and can also be obtained by
logging into a SS. Please refer to ‘SS Manager Configuration Guide’ for detail
information.
SS Name – A unique user name should be given to the SS to identify it.
It can also give the location or the customer name to represent the SS.
PCID – PCID is used to associate a set of QOS parameters to the SS for downlink and
uplink service flow that are created with ‘Add QoS’. A number of PCIDs can be selected
depending on requirements.
Once PCIDs are selected, the user can associate classifiers which each PCID. Classifiers
are used to associate a particular traffic data to the Service flow (identified by QOS
parameters in BS).

1.40.4 Classifiers
Classifiers are used for routing of packets to particular SS using IP rules (Classifier
maps an IP packet to a particular connection). Its length is 2 bytes (maximum number
of classifiers that the SS supports). It is mandatory to have classifiers for each PCID.
Type – There are two types of classifiers.
Static: User has to add the IP address of the system or router on the subscriber
station side as a classifier.
Dynamic: If DHCP is enabled at the subscriber station side, it will obtain an IP address
dynamically. In this case DHCP must be enabled at PC/Router connected to the
subscriber station.
Index – This specifies the priority for the classifier, which is used for determining the
order of the classification. Classifiers may have priorities in the range 0–255 with the
default value being 0.
Type of Service – The values of this field specify the matching parameters for the IP
type of service byte range and mask. An IP packet with IP type of service (ToS) byte
value “ip-tos” matches this parameter if tos-low ≤ (ip-tos AND tos-mask) ≤ tos-high. If
this field is omitted, then comparison of the IP packet ToS byte for this entry is
irrelevant.
Minimum: 0 (for low, high and mask)
Maximum: 65535 (for low, high and mask)
IP Source Address and Mask – This parameter specifies a IP source address
(designated “src”) and its corresponding address mask (designated “dmask”). An IP
packet with IP destination address “ip-dst” matches this parameter if src = (ip-dst AND
dmask). If this parameter is omitted, then comparison of the IP packet source address
for this entry is irrelevant.
Protocol Source Port Range: The value of the field specifies a range of protocol source
port values. Classifier rules with port numbers are protocol specific; i.e., a rule on port
numbers without a protocol specification shall not be defined. An IP packet with
Libra MAX User Guide
Base Station Configuration: Subscriber Station Association (SS) Page 90 of 120
protocol port value “src-port” matches this parameter if src-port is greater than or
equal to sport low and src-port is less than or equal to sport high. If this parameter is
omitted, the protocol source port is irrelevant. This parameter is irrelevant for protocols
without port numbers.
Minimum: 0 (low, high and mask)
Maximum: 65535 (low, high and mask)
Protocol Destination Port Range – The value of the field specifies a range of
protocol destination port values. Classifier rules with port numbers are protocol specific;
i.e., a rule on port numbers without a protocol specification shall not be defined. An IP
packet with protocol port value “dst-port” matches this parameter if dst-port is greater
than or equal to dport low and dst-port is less than or equal to dport high. If this
parameter is omitted the protocol destination port is irrelevant. This parameter is
irrelevant for protocols without port numbers.
Minimum: 0 (low, high and mask)
Maximum: 65535 (low, high and mask)
Ethernet Source MAC Address – This parameter specifies a MAC source address
(designated “src”) and their corresponding address mask (designated “msk”). An IEEE
802.3/Ethernet packet with MAC source address “ethersrc” corresponds to this
parameter if src = (ethersrc AND msk). If this parameter is omitted, then comparison
of the IEEE 802.3/Ethernet source MAC address for this entry is irrelevant.
Notation: xx:xx:xx:xx:xx:xx
Ethernet Destination MAC Address – This parameter specifies a MAC destination
address (designated “dst”) and its corresponding address mask (designated “msk”). An
IEEE 802.3/Ethernet packet with MAC destination address “etherdst” corresponds to
this parameter if dst = (etherdst AND msk). If this parameter is omitted, then
comparison of the IEEE 802.3/Ethernet destination MAC address for this entry is
irrelevant.
Notation: xx:xx:xx:xx:xx:xx
The format of the Layer 3 protocol ID in the Ethernet packet is indicated by type,
eprot1, and eprot2 as follows:
If type = 0, the rule does not use the Layer 3 protocol type as a matching criteria. If
type = 0, eprot1, eprot2 are ignored when considering whether a packet matches the
current rule.
If type = 1, the rule applies only to SDUs that contain an Ethertype value. Ethertype
values are contained in packets using the DEC-Intel-Xerox (DIX) encapsulation or the
Sub-Network Access Protocol (SNAP) encapsulation (IEEE 802.2, IETF RFC 1042)
format. If type = 1, then eprot1, eprot2 gives the 16 bit value of the Ethertype that the
packet shall match in order to match the rule.
If type = 2, the rule applies only to SDUs using the IEEE 802.2 encapsulation format
with a Destination Service (DSAP) other than 0xAA (which is reserved for SNAP). If
type = 2, the lower 8 bits of the eprot1, eprot2 shall match the DSAP byte of the
packet in order to match the rule.
Libra MAX User Guide
Base Station Configuration: Subscriber Station Association (SS) Page 91 of 120
If the Ethernet SDU contains an IEEE 802.1D and IEEE 802.1Q Tag header (i.e.,
Ethertype 0x8100), this object applies to the embedded Ethertype field within the IEEE
802.1D and IEEE 802.1Q header.
To add a classifier, go to ‘SS List’ window and click on the subscriber of interest in the
list. Then on the screen that appears as shown on Figure 0-24. Click on ‘Add Classifier’

1.42.5 Upload Configuration
Once you have saved a configuration file, the tar.gz file can be used to restore the
previous configuration of the base station, or to load a known good configuration from
another base station.
NOTE: Prior to restoring a configuration, EION recommends that the Base
Station is reset to default values and rebooted.
ATTENTION: Ensure that the configuration filename is saved as
“config.tar.gz” Special characters in the filename will cause
the upload configuration to fail.

1.44 IP Address Recovery
Loss of the Base Station’s IP address leads to loss of accessibility to the Base Station
and ability to manage the Base Station. This feature provides the ability to recover the
accessibility to the Base Station by assigning a new IP address to the Base Station.
This feature would require a utility program called “iprecover” to be executed from a
linux desktop that is connected to the Ethernet interface of the Base Station.
The iprecover utility can be executed as shown below. Executing the utility without
specifying any parameters will display a brief help on the various parameters that
should be provided while executing the utility.
Figure 0-31: Executing the IP recovery utility without specifying any
parameters will display a help file
The values for each of the parameters in the iprecover utility adhere to the following:

1.45 Sector Card Management
Sector card plugs into any of the gray slots of the indoor unit chassis and is a part of
Libra MAX-HD Chassis. This allows configuration of multiple Base Stations as well as
their monitoring. It also provides the data path for multiple BS ODUs to their data
source (such as router or a switch) inside the NOC.
Since one sector card can manage multiple BS ODUs, management of sector card itself
is less frequent and is usually done at the time of its installation only. Most common
parameters to be changed on sector card are time zone and its network parameters
(such as IP address and subnet mask). Besides, sector card can be reset or shutdown
using its management interface.

Figure 0-3: WiMAX Radio Settings, AFS Disabled
Figure 4: WiMAX Radio Settings with AFS Enabled
BS ID – It is the identifier of the BS to which the subscriber station is to be associated.
It is usually the MAC of the BS ODU. By default, SS is configured to be associated with
any Libra MAX-58 BS ODU.
BS ID Mask – This is the mask for BS ID. Its default value is 00:00:00:00:00:00
Duplex Mode – This is set to TDD as only TDD is supported at present.
AFS Support – Automatic Frequency Scanning mode allows selection of frequency
automatically within the range and in step size specified. Set the start and end
frequency range including the step size and a center frequency. Subscriber station will
then scan within the range of frequencies and locks the center frequency to the one
where the signal strength is optimum.
DL-Center Frequency – This should be set to that of the BS ODU. For a SS to
communicate with the BS, both have to be on the same frequency. Since, it’s a TDD
system, both uplink and downlink frequency will be the same.
Channel Bandwidth – For BS Type FBW-1050 (5.725 to 5.875 GHz), channel
bandwidth is 10 MHz. Larger the bandwidth, higher the throughput.

Troubleshooting
1.60 Preventative Maintenance
Administering and maintaining your system properly can prevent many problems and
alert you to minor problems before they become serious. Some recommendations
follow.
•
Measure and document system performance at the time of the original
installation.
•
Change menu passwords so that only authorized people can reconfigure the
system.
•
Maintain the integrity of the system design when adding to or changing a
system. The introduction of new elements to a system can cause problems
unless you revise the network plan to take into account the changes. For
example, improper installation of a co-located antenna can add unwanted
system interference.
•
Keep records of all changes. Especially document the addition of units,
hardware and software changes, and changes to configuration settings.
Configuration errors often cause other problems. Current records can be
compared with original installation records and function as benchmarks to help
in troubleshooting.
•
Keep a log of past and present problems and solutions. Store the log on-site for
easy reference, if possible. The log identifies common failure points and fixes.
Before contacting EION’s Technical Assistance Center, document the symptoms
of the fault and the steps taken to diagnose and fix the problem. Record the
current configuration of the system.
•
Perform preventive maintenance at a regular interval, for example every six
months.
•
Perform link monitor tests to verify the system after periods of extreme
weather, and inspect towers, antennas, ODUs, cables, and connectors for
damage.
•
Monitor system performance regularly. Environmental change as well as normal
wear and tear on components can affect system performance.
•
In some cases a bench test is a useful tool in diagnosing problems.
1.61 Troubleshooting Areas
There are four areas to keep in mind with troubleshooting:
1. Network integrity: The continued performance and reliability of a network
depend upon maintaining the integrity of the network. If you change a
network’s design, you will affect its operation. Be aware of recent changes to
your network.
2. Quality of RF links: Data communication depends first on good RF links. If you
establish and maintain high-quality RF links, then you can be sure the links will
carry high-speed data. If the quality of the RF links degrades for some reason,
the quality of the data and the associated performance will also degrade.
Libra MAX User Guide
Troubleshooting: Preventative Maintenance
Page 112 of 120
3. Radio Hardware: This consists of three parts: Main unit, antenna, and
mounting hardware.. (To verify the radio performance, you can run diagnostic
tests, such as RSSI and CINR)
4. Correct Unit Configuration: Units must be configured properly, according to the
network plan. Configuration errors can cause an inability to communicate or
poor performance. The addition of units or other changes to your system may
require you to change configuration settings.

Appendix A: Definitions
Base station (BS): Generalized equipment set providing connectivity, management,
and control of the subscriber station (SS).
Subscriber station (SS): Generalized equipment set providing connectivity between
subscriber equipment and a base station (BS).
Multicast polling group: A group of zero or more subscriber stations (SSs) that are
assigned a multicast address for the purposes of polling.
Security association identifier (SAID): An identifier shared between the base
station (BS) and subscriber station that uniquely identifies a security association (SA).
IPV6: A network layer for packet-switched internetworks. It is designated as the
successor of IPv4, the current version of the Internet Protocol, for general use on the
Internet.
Ipv4: The fourth iteration of the Internet Protocol (IP) and the first version of the
protocol to be widely deployed. IPv4 is the dominant network layer protocol on the
Internet and apart from IPv6 it is the only standard internetwork-layer protocol used on
the Internet.
MAC Address: Media Access Control Address, a quasi-unique identifier attached to
most network adapters (NICs). It is a number that acts like a name for a particular
network adapter.
IP Address: A unique address that certain electronic devices currently use in order to
identify and communicate with each other on a computer network utilizing the Internet
Protocol standard (IP).
SAID: Security Association Identifier is an identifier shared between the base station
and a subscriber station that uniquely identifies a security association (SA).
PCID: Provisional Connection identifier. It’s a provisional service given by the operator.
PCID is equivalent to provisional service flow in IEEE 802.16D standard.
QOS: Quality of Service refers to resource reservation control mechanisms rather than
the achieved service quality. Quality of Service is the ability to provide different priority
to different applications, users, or data flows, or to guarantee a certain level of
performance to a data flow.
Classifier: A classifier is a set of matching criteria applied to each packet entering the
IEEE standard 802.16 network. It consists of some protocol-specific packet matching
criteria (destination IP address, for example), a classifier priority, and a reference to a
CID. If a packet matches the specified packet matching criteria, it is then delivered to
the SAP for delivery on the connection defined by the CID. Implementation of each
specific classification capability (as, for example, IPv4 based classification) is optional.
The service flow characteristics of the connection provide the QoS for that packet.
Configuration: A set of parameters by which a BS (base station) is configured to take
specific values and operate in that range.
Events: The information of the particular BS (base station) which is reported by a BS
on occurrence of state changes and faults.
Slab: Identifies a period of time used for billing purposes.
Upgrade: To update the software on the BS from existing load to another load.
Mapped SS: Shows the numbers and the detail of the SS which are associated to the
