Axxcelera Broadband Product Install Manual Page 12 of 71 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. 1.3.1 AB-Access System Architecture Figures 1-1 and 1-2 show an AB-Access System’s typical deployment and network architecture.

Base Station elements may include: • Access Point • AB-Extender • Switch
Axxcelera Broadband Product Install Manual Page 14 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.
Axxcelera Broadband Product Install Manual Page 15 of 71 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.
Axxcelera Broadband Product Install Manual Page 16 of 71 2.3 Required Tools and Equipment This section lists all the extra tools and equipment mentioned in this guide that you will need to perform the installation. None of the items listed in Table 2-1 are supplied with the kit, so make sure you gather everything you need before you start. Use the table below to check exactly what you will need (this will depend on where you are going to install the outdoor transceiver).

The steps you will perform are: • Determine which Access Points you can communicate with. • Determine the direction of available Access Points from the house or building. • Select an Access Point with an unobstructed Line of Sight (LOS). Attention! It is very important that you choose a CLEAR LINE OF SIGHT for the placement of your Access Point Units and Subscriber Units. 2.5.1 What You Need • Compass (or protractor).
Axxcelera Broadband Product Install Manual Page 18 of 71 • Area map with an accurate direction legend showing magnetic north. • Access Point locations – these should be provided by 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: c 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 19 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 2-4. 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 20 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 21 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.
Axxcelera Broadband Product Install Manual Page 22 of 71 Section 3 3 Base Station Installation 3.1 System Overview This section briefly describes the AB-Access hardware and software system components that 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 23 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.
Axxcelera Broadband Product Install Manual Page 24 of 71 Section 4 4 Access Point Installation 4.1 Before You Start This section lists the information needed to install an AP. 4.2 Information Required Before you perform the installation, a site survey should have been performed by the service provider. From this, you will need to know: • Number of APs to install • Where the outdoor transceivers will be mounted (antenna mast, pole or building) • Heights at which the outdoor transceivers will be mounted. • Transceiver directional information (azimuth and elevation). You will probably be installing six APs on a mast or pole, giving 360 degree coverage in 60 degree sectors, as shown in Figure 4-1.

Axxcelera Broadband Product Install Manual Page 55 of 71 Table 6-5 Required Tools and Equipment Tools Required Equipment Required Quantity Phillips-head screwdriver Screws 2 Flat head screwdriver Wallboard inserts 2 Power drill 1 1/8 inch drill bit 1 1. Select a location for the junction box. This should be: • Somewhere you can easily connect to your PC and a power outlet. • Somewhere that is accessible for service and troubleshooting (not too close to the floor). 2. Remove the two screws which attach the junction box faceplate to the wall mount. 3. Set aside the faceplate with PCB and jack. Attention! Be careful not to damage the two LEDs when removing the PCB. 4. On the Wall Mount portion of the Wall Box, use a flat head screwdriver, or a pair of thin-nosed pliers, to break out the pre-scored section of casing wall along the bottom edge of the junction box (see Figure 6-7). This is where later on you will route the interconnect cable. Figure 6-7 Junction Box Wall Mount (Face Plate and PCB Removed) 5. Using the wall plate as a template, mark the mounting hole locations, as shown in Figure 6-7. 6. Drill 1/8 inch diameter holes at the marked locations. 7. Insert the wallboard inserts. 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 prepared and routed the interconnect cable and grounded the system. 6.5 Installing the Interconnect Cable 6.5.1 Routing the Interconnect Cable Now that you have installed the outdoor Subscriber Unit and indoor junction box, you are ready to route the interconnect cable.
Axxcelera Broadband Product Install Manual Page 56 of 71 1. Select where the cable will enter the building from the outside (Figure 6-8). NOTE - Add adrip loop at wallpenetration toprevent waterfrom entering Figure 6-8 Interconnect Cable Routing Solutions 2. Once you have chosen the route, determine the length of cable required. Allow three extra feet on each end to allow for strain relief as well as any bends and turns. 3. Install the cable, leaving the ends free and ready to fit the RJ-45 connector (transceiver end), and install to the indoor junction box. 4. Remember to form a drip loop on the exterior of the building where the cable enters the penetration. This will help prevent water from entering. 6.5.2 Preparing the Interconnect Cable Table 6-6 shows the tools you need to install an RJ-45 connector on the outdoor subscriber end of the interconnect cable. Table 6-6 Required Tools and Equipment Tools Equipment Quantity Crimping tool (specific to RJ-45 used) RJ-45 connector (metal bodied) 1 Wire stripper Small wire cutters 1. Remove the grommet (Figure 6-9) and clamping plate from the Subscriber Unit by undoing the two screws. Be careful not to lose them if you are working on a ladder.
Axxcelera Broadband Product Install Manual Page 57 of 71 NOTE: The Grommet is made of a special conductive material used to complete the ground between the Subscriber Unit and indoor junction box. Figure 6-9 Grommet Location -- Underside of Subscriber Unit 2. Insert the cable end through the grommet clamping plate (Figure 6-10). 3. Insert the cable end through the grommet. The tapered end of the grommet should be opposite the cable end. 4. Strip 1 inch of insulation off the cable end. Leave 3/8 inch of shielding showing, and trim the wire ends flat ½ inch from there. 5. Using a piece of 1inch squared tinned copper foil, wrap the foil around the shield/braid and sheath with the left edge aligned with the edge of the braid, as shown in the following Figure 6-10.

Using pin 1 as a reference, insert the individual wires into the channels of the RJ-45 connector. Each wire should penetrate the channels until flush with the connector end. The copper foil tape should extend past the casing of the RJ-45 connector by approximately ½ inch. 8. When all wires are inserted into the channels in their correct order, use the crimping tool to permanently crimp the wires to the connector. Attention! Carefully read the instructions for the crimping tool you are using. Use the correct crimping tool for the RJ-45 connector you are using. Incorrect installation of the RJ-45 connector may result in a bad connection between the outdoor transceiver and the indoor junction box. 6.5.3 Connecting to the Outdoor Subscriber Unit Transceiver Now that you have prepared the interconnect cable, you are ready to connect the cable to the outdoor Subscriber Unit. Attention! Always Disconnect Power from wall box BEFORE inserting RJ-45 connector into transceiver. This prevents arcing damage from occurring. 1. Insert the RJ-45 connector into the receptacle located underneath the outdoor Subscriber Unit (refer to Figure 6-12). Make sure that the connector tab engages the slot in the receptacle. 2. Slide the grommet up the cable and press it into the bottom of the outdoor transceiver. 3. Slide the grommet clamp up the cable and align the holes with the mounting holes on the bottom of the outdoor transceiver. 4. Insert the two screws in the mounting holes and tighten until the grommet has a slight bulge. Be sure to tighten both screws equally so that the grommet is seated correctly. 5. Secure the interconnect cable to the mounting pole with the cable clip, as shown in Figure 6-11.

Strip 2 inches of insulation off the junction box end of the interconnect cable. Attention! Don’t cut off the shield from the cable – you will need it to ground the system later. 12. Insert the cable end through the notched out section of the junction box. 13. 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. 14. Using Figure 6-12 as a guide, use the 110 punch down tool to punch down each wire into the slot on the punch down block. Figure 6-12 Interconnect Cable Connections to Indoor Junction Box
Axxcelera Broadband Product Install Manual Page 60 of 71 15. 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. 6.6 Grounding the System The AB-Access System must be properly grounded in order to protect it and the building it is installed on from lightning damage. This requires grounding both the outdoor transceiver and indoor junction box. The following Table 6-8 describes the tools you will need to ground the system. Table 6-8 Required Tools and Equipment Tools Equipment Quantity Mallet Grounding rod 1 Wire stripper #8 braided copper wire Wire cutters Grounding lugs 2 Hex wrench Grounding clamp 1 6.6.1 Installing a Grounding Rod 1. Place the grounding rod to allow for the shortest possible path from the grounding cable to the outdoor Subscriber Units. 2.

Axxcelera Broadband Product Install Manual Page 66 of 71 Glossary TERM DEFINED Access Point An Access Point (AP) is a component of a Base Station (BS) that contains the antenna used to communicate with a Subscriber Unit (SU). Anchor Switch The Anchor Switch (AS) is an ATM access switch that is a component of a Base Station (BS). Antenna A device for transmitting and/or receiving radio waves. Asynchronous A data transmission method in which data may be sent at irregular intervals (without reference to clock signals). ATM Asynchronous Transfer Mode is a high-performance, cell-oriented switching and multiplexing technology, which utilizes fixed-length packets to carry different types of traffic. It integrates the multiplexing and switching functions, is well suited for bursty traffic, and allows communications between devices that operate at different speeds. ATM Switch The ATM switch provides layer 2 switching of ATM cells through virtual circuits. An ATM switch is contained in the SU, the AP, and the AS. Available Bit Rate (ABR) Service that provides rate-based flow control and is aimed at data traffic such as file transfer and e-mail. Azimuth The angle along the horizon usually referenced to north. Bandwidth The data carrying capacity of a communications channel, measured in Hertz as the difference between the highest and lowest frequencies of the channel. Base Station The Base Station is the part of the AB-Access System that sends signals to and receives signals from the Subscriber Units (SUs) to enable communication with the WAN. Baud A measure of data transmission speed. The baud rate denotes the number of symbols per second. Bit Error Rate The Bit Error Rate (BER) is the fraction of transmitted bits that are received in error. Cell A 53-Byte packet of data used in ATM networks. Also used to refer to the coverage area of one Base Station. Constant Bit Rate (CBR) Service that operates on a connection basis and offers consistent delay predictability; used for applications such as circuit emulation, voice, and video. Control Server The Control Server (typically one per BS) is a computer responsible for management of the BS, its APs, and the associated SUs. DS1 A data transmission rate of 1.544 Mbps, also referred to as a T-1.DS3 A data transmission rate of 45 Mbps
Axxcelera Broadband Product Install Manual Page 67 of 71 TERM DEFINED Element Management System The Element Management System (EMS), located on a workstation at an appropriate point in the network, allows you to configure, control, and monitor all components of the AB-Access System. MIB Management information base allows external management system access. Multiplexer A multiplexer is device or system capable of combining elementary streams into one aggregate transport stream. Network A network is an interconnection of computer systems, terminals, or data communications facilities. OC3 A data transmission rate of 155 Mbps Packet A packet is a sequence of data, with associated control information, that is switched and transmitted as a whole. Packet Switching Packet switching is the data transmission method that divides messages into standard-sized packets for greater efficiency of routing and transport through a network. Parsing Parsing is the process of analyzing a data stream and breaking it down into more easily processed components. Permanent Virtual Circuit Provides end-to-end connectivity for transmission in a network. Point-to-Point A single communication circuit connecting two locations. Point-to-Multipoint A communications circuit connecting one location to many locations. Radio Frequency Radio frequency (RF) is a portion of the electromagnetic spectrum in the frequency range of 100 kHz to 20 GHz. Subscriber Unit The Subscriber Unit (SU) is the part of the AB-Access System that is installed at the customer premises and provides communication with the Base Station (BS). Synchronous A data transmission method in which data transfer is at a fixed rate. The transmitter and receiver are both controlled by clock pulses. TCP/IP Transmission Control Protocol/Internet Protocol, a layered set of protocols that allows sharing of applications among PCs, hosts, or workstations in a high-speed communications environment. The suite of protocols is designed to allow communication between networks regardless of the technologies implemented in each network. TDD Time Division Duplex, the transmission method where a single channel is used to alternately carry data in each direction of a link.Time-Division Multiplexing A form of multiplexing used with digital signals. A device scans individual channels in rotation, takes bits from each channel, transmits the bits in a string (according to a predetermined sequence), and repeats the process.
Axxcelera Broadband Product Install Manual Page 68 of 71 TERM DEFINED Transmitter A transmitter is an electronic device, consisting of oscillator, modulator, and other circuits, that produce a radio or television electromagnetic wave signal for radiation into the atmosphere by an antenna. Unspecified Bit Rate Service that operates on a connection basis and allows for raw cell or best effort transport by the network. In this service, cells are transported by the network whenever bandwidth is available and traffic is presented by the user. Data using UBR service is more apt to be discarded during peak traffic times in deference to data using other classes of service. Uninterruptible Power Supply An optional BS element used to provide power in the event of an AC power failure. Variable Bit Rate-Real Time (VBR-RT) Service that operates on a connection basis and offers very low delay variance but requires access to a variable amount of network bandwidth; used for such applications as packet video and voice. Variable Bit Rate-Non-Real Time (VBR-NRT) Service that operates on both a connection and connectionless basis and allows delay variance between the delivery of cells; used for data applications which have potentially bursty traffic characteristics, including LAN interconnect, CAD/CAM, and multimedia. Virtual Circuit A logical connection, not a physical connection, provides multiple connections that can be defined simultaneously across a single network facility, with each connection having flexible bandwidth.
