PRODUCT INSTALLATION MANUAL
for Subscriber Units, Base Stations, Access Points
and AB-Extender Units
Issue 5.4
Revision 1
July 27, 2004
Preface
AB-Access™ System technology enables high-speed, broadband Internet access for fast data
transmission, full streaming video, real-time video conferencing, and web surfing. Axxcelera
Broadband’s wireless point-to-multipoint and point-to-point solutions (AB-Extender) for fixed
networks enables our customers to easily leap-over existing infrastructure, making the initial
investment significantly lower than that required for wired alternatives.
Axxcelera Broadband’s, patent pending, Packet-on-Demand technology delivers up to 10 times
the effective Internet data throughput of existing network configurations. Our technology
provides a last-mile solution, when deployed between networks and business/residential Internet
users. AB-Access System’s low-cost, wireless infrastructure means that a complete network can
be installed in days or weeks, instead of the typical months or years. Since AB-Access
architecture is highly scalable, our customers’ wireless network can grow as quickly as their
business grows or as bandwidth needs evolve.
The main tasks covered in this manual are configuring and managing network elements, such as
Base Stations, Subscriber Units, Access Points, AB-Extender Units, Anchor Switches, and
Control Servers. Definitions of all the terms and abbreviations used in this manual can be found
in the Glossary at the end of this manual.

Section 1
1 AB-Access Product Overview
1.1 AB-Access System
The Axxcelera Broadband AB-Access System is a broadband, fixed, wireless access network for
Internet, data, video, and voice applications. AB-Access can enhance or replace existing
networks, wired or wireless, or be used to develop new networks. The AB-Access System offers:
•
Point-to-Multipoint (PMP) Wireless Access Network
•
Point-to-Point (PTP) Wireless Access Network [AB-Extender]
•
End-to-End Connectivity
•
Spectrum Efficiency per Offered Load
•
Powerful, Flexible Elements.
1.2 AB-Access Network
The AB-Access network consists of wireless 25 Mbps cells similar in topology to the cellular
networks of today. AB-Access networks are designed for rapid and easy deployment, and
constructed from a number of Base Stations deployed in a conventional cellular pattern.
Deployment can vary from a number of small island sites to complete coverage of a chosen
geographical area. AB-Extender allows these cell sites to be linked together with high-speed,
long range, point-to-point connections.
1.3 System Components
The AB-Access System is comprised of the following major components:
•
Subscriber Unit (SU) – Located at customer premises and provides either ATM
or standard IP over Ethernet connectivity.
•
Access Point (AP) - The Access Point is the cornerstone component of the
Base Station. The AP is the interface between the Service Provider’s terrestrial
network and the wireless fabric. Each AP has the capability to provide network
service at the Physical, Data Link, and Network Layers of the OSI reference
model.
•
AB-Extender (EX) - The AB-Extender is the inter-Base Station linking
component. The EX is the interface between the Service Provider’s terrestrial
network and the wireless PMP fabric. Each EX has the capability to provide
network service at the Physical, Data Link, and Network Layers of the OSI
reference model. Each EX can provide ATM or Ethernet backhaul.

AB-Extender
•
Switch
Axxcelera Broadband
Product Install Manual
Page 13 of 71
•
Termination Point and Lightning Arrestor
•
48 VDC Power Supply
•
Uninterruptible Power Supply (UPS) (optional).
1.3.3 Subscriber Unit Function
The Subscriber Unit is an integrated device that mounts externally at the customer site. This
device provides either ATM or Ethernet communications via the 25Mbps ATM wireless
connection with the Base Station. Subscriber Unit elements may include:
•
Internal Junction Box
•
Cabling.
•
Switch, hub or router
1.3.4 System Configuration Selection
Before installing a new unit or upgrading a unit, the network manager must know what
configuration option to use. The upgrade process will place a unit in a certain state. The state of
this unit will be very important depending upon whether the unit is already being used in
production or about to be put into use. Units in production will need to be upgraded and placed
back into production using the configuration currently in place. New units will require the
proper configuration in order to come online fast and efficiently. This whole process relies on
the fact that the units are programmed properly.
Units operating in static mode will want to retain this mode. Selecting the wrong configuration
may result in a static unit being placed in a dynamic registration mode, making it potentially
unmanageable remotely. Similarly, upgrading a unit running in a routed topology to a bridge
topology will have a significant impact on functionality.
For more information about configuring your AB-Access System, reference the AB-Access
Configuration and User’s Guide.
Following are instructions for setting up Subscriber Units, Base Stations, AB-Extender and
Access Points. A Glossary of definitions and acronyms is at the end of this manual.

Section 2
2 Getting Started
2.1 Skills Required
The AB-Access Product Installation procedures require some construction-related experience
using both power and hand tools. Answer the following questions to determine whether you
have the skills to attempt the installation.
•
Are you comfortable working at heights?
•
(The installation may require you to climb a ladder and work at heights
depending on where you need to install your outdoor transceiver. Keep in mind,
you will also carry tools and equipment with you to the installation site.)
•
Have you ever installed an RJ-45 connector to an Ethernet cable?
•
(This is required to connect the outdoor transceiver and the indoor junction box
or access panel.)
•
Have you run telephone cable, wired a telephone jack, or connected telephone
wire connections to a punch down block?
•
Have you ever installed expansion shields into brick or masonry walls?
•
(This requires drilling holes in masonry using masonry drill bits.)
•
Have you ever wired an electrical outlet?
•
Although you won’t wire an outlet, you will be required to run ground wires and
clamp them to an earth grounding rod or a cold water pipe.
If you can perform all the above tasks, then you should be able to install the AB-Access System.
If you are unsure of your ability to perform these tasks, contact a more qualified installer.
2.2 Information Needed From Your Service Provider
Your service provider should have supplied you with the following information. Please contact
your service provider before commencing installation, if you do not have all of this information:
•
Locations of any local Access Points, which you should be able to connect to.
•
The IP address of the radio being installed.
•
An IP address and subnet mask needed to configure a Test PC. This is so you
can check to see if your SU is working, align your outdoor transceiver correctly,
and confirm that you can connect to your service provider.

2.5.2 Access Point Locations
If you are installing the unit without the aid of a qualified installer, you need to determine the
general direction of any Access Points from your house or building. You may be able to ‘see’
several APs, depending on your coverage area.
Attention! The following method uses a compass to find the bearing of any APs from your
site. An alternative method is to use a protractor to measure the angle between North and a
line to the AP from your site. This tells you the compass bearing to use when aligning your
outdoor transceiver.
1. On your map, mark the location of your house or building
2. Mark the locations of any Access Points – these should have been supplied by your service
provider:
Figure 2-2 Access Point Locations
3. Place the compass on the map on or near the magnetic north indicator.
4. Turn the compass so that the magnetic north indicator needle aligns with the N or North
indicator on the compass body.
5. Rotate the map, keeping the compass stationary, so the map’s North Indicator aligns with the
North Indicator of the compass (see Figure 2-3).
6. Move the compass over your location on the map and read off the bearing to the AP.
Axxcelera Broadband
Product Install Manual
Page 18 of 71
Figure 2-3 Aligning the Compass and Map
7. Write down the directions (compass bearings) of your Access Points. For example, in Figure
2-3, Access Point A is located northwest of the building and Access Point B is located
between north and northeast. (If you can be more accurate than this, you will get better
reception when you install your outdoor transceiver.)
2.5.3 Selecting an Access Point
In order for your AB-Access System to work correctly, you MUST establish a clear line of sight
to one or more of the Access Points recommended by your AB-Access System provider.
1. Using the compass bearings you wrote down in the previous section, walk around your
building to find a suitable line of sight path to mount your outdoor transceiver – see Figure 24.
Attention! A clear line of sight means a path unobstructed by trees,
dense foliage, or other buildings.
If necessary, move to an upstairs window or rooftop location to better view the surrounding area
for possible blockages in the path. Also, be sure to consider seasonal changes. A location that is
unobstructed in the winter may be obstructed by foliage in the spring, summer, and autumn.
Axxcelera Broadband
Product Install Manual
Page 19 of 71
Figure 2-4 Selecting an Access Point
You should mount your outdoor Subscriber Unit as high as possible on your building, and align
it to the compass reading you have just taken. For example, the previous Figure 2-4 shows the
path to Access Point A obstructed by a cluster of trees. However, there are two possible
mounting locations for the outdoor Subscriber Unit giving a clear line of sight to Access Point B.
Attention! Your outdoor transceiver has a beam width of approximately 20 degrees. You
will need to be fairly accurate when aligning your transceiver to the compass bearing you
wrote down earlier (the more accurate your compass readings, the better).
2. If you do come up with two or more suitable locations for the outdoor Subscriber Unit,
choose the one that is easiest for you to reach, when it comes to installing!
2.5.4 AB-Extender Locations
In order for your AB-Extender link to work correctly, you MUST establish a clear line of sight
between the Extender AP and Extender SU.
Attention! A clear line of sight means a path unobstructed by trees,
dense foliage, or other buildings.
Attention! Your outdoor transceiver has a beam width of approximately 10 degrees. You
will need to be fairly accurate when aligning your transceiver to the compass bearing you
wrote down earlier (the more accurate your compass readings, the better).
Axxcelera Broadband
Product Install Manual
Page 20 of 71
Follow the same instructions for aligning and locating the AB-Extender units as for the standard
AP and SU. Note: the difference in beam width will make alignment more difficult but has the
advantage of lower susceptibility to interference.

comprise a Base Station.
Figure 3-1 Base Station Overview
3.2 Access Points
Figure 3-2 Outdoor Access Point and Mounting Pole
Axxcelera Broadband
Product Install Manual
Page 22 of 71
A Base Station can have up to six Access Points. Each AP consists of an outdoor transceiver
(which contains the antenna and associated electronics that transmit and receive broadband
wireless signals to and from Subscriber Units) and an indoor wallbox or access panel.
3.3 AB-Extender Units
A Base Station may have a number of AB-Extender units. Each EX consists of an outdoor
transceiver and an indoor wallbox or access panel.
3.4 A Note On Cabling
Attention! Most of the cabling used in the AB-Access System is CAT5. You will need to be
aware of the following limits on CAT5 cable lengths:
•
The interconnect cable from the indoor junction box to an outdoor transceiver
must be less than 60 meters. This is due to DC resistance loss over the distance
of the cable run.
•
The combined length of ATM or Ethernet interconnect cable (from the radio to
the switch) must be less than 100 meters.

3. Reinstall the PCB into the junction box using the two screws, allowing enough of the
interconnect cable to be able to reach the punch down block and wrap around the mounts of
the cover plate for strain relief.
4. Using Figure 4-13 as a guide, use the 110 punch down tool to punch down each wire into the
slot on the punch down block.
Figure 4-13 Interconnect Cable Connections to Indoor Junction Box
5. Snip off excess wire ends, if necessary.
Attention! Avoid excessive wire loops when connecting the wire to the punch down block.
For now, set the junction box to one side leaving it disassembled. You will reassemble it and
mount it on the wall when you have grounded the system.
4.5.2.4 Mark the Access Point Cables
Attention! Step 1 is important, and will enable the network installer to configure the
system easily.
1. Mark the cable with a permanent label and make a note so that the network installer knows
which outdoor AP transceiver is connected to which port on the Access Panel junction box.
4.6 Grounding the System
The AB-Access System must be properly grounded in order to protect it and the structure it is
installed on from lightning damage. This requires:
Axxcelera Broadband
Product Install Manual
Page 33 of 71
1. Grounding all the outdoor transceivers as shown in Figure 4-12.
2. Grounding the Access Panel to the rack.
4.6.1 Grounding the Outdoor Access Points
1.
Place the grounding rod so as to allow for the shortest possible path from the grounding
cable to the outdoor Access Points.
2. Drive the grounding rod into the ground at least eight inches from the ground surface.
3. Attach a grounding clamp to the grounding rod. You will use this clamp to attach grounding
wires for both the outdoor transceiver and indoor junction box, reference Figure 4-14.
Figure 4-14 Ground Connections to Access Point Transceiver
Attention! The grounding wire should be long enough to reach from the mounting pole to
the grounding rod with 3 to 6 extra feet allowed for strain relief.
4. Connect a ground lug to one end of the grounding wire.
5. Remove one of the lower mounting screws of the mounting pole. Insert a screw through the
grounding lug terminal and re-install it to the mounting pole.

box to the grounding rod. The wire should be long enough to reach from the junction box to the
grounding rod with 3 to 6 extra feet to allow for strain relief.
1. Feed the grounding cable through the broken out section of the wall cover (alongside the
interconnect cable).
2. Connect a ground lug to the grounding cable by crimping the lug to the wire, as shown in
Figure 4-16.
3. Remove the hex nut on the grounding post, as shown in Figure 4-16.
4. Install the grounding lug terminal onto the grounding post.
5. Attach the wire shield of the interconnect cable to the ground post. You may need to crimp
or solder an extra length of wire to the shield in order to attach it to the grounding post.
6. Re-install the hex nut to the grounding post and tighten.
7. Attach the grounding wire to the clamp on the grounding rod.
8. Use the provided small wire tie to firmly attach the interconnect cable to the ground lug.
