The QuickBridge is a point-to-point, outdoor, wireless system offering a high-capacity alternative to wired data networks. Using IP packet radio transmitters, standard Ethernet interfaces, and an easy-to-deploy design, the QuickBridge system enables a broad bandwidth link between two locations.
The product’s principle components are a radio and a power adapter. The radio has a self-contained
antenna enclosed in a weatherproof, 10” by 10” container, which can be mounted to the side of a building, on a pole, or on a tower structure.
Power and Ethernet connections are supplied through a UV-protected, CAT5 cable attached to a power adapter. The power adapter should be located either in a weatherproof enclosure located near the radio or inside a building. The radio then can be connected to a switch or hub on your network, or directly to a PC.
This book is designed for network engineers and field service personnel who will install, maintain, and troubleshoot the QuickBridge. It assumes that you have an understanding of networks in general, and a basic understanding of the following subjects:
The minimum system requirements for installing and running the QuickBridge Manager are as follows:
There are several planning factors to be considered prior to installing the radio system. In addition to selecting the installation site, you must:

Perform the following steps in this chapter to install the
QuickBridge system:
You should have the following tools available before installing the Tsunami QuickBridge radios:
The product’s shipping boxes should be left intact and sheltered until arrival at the installation site. Carefully unpack the Tsunami QuickBridge shipment and check for any shipping damage or missing parts. There are two sets of equipment in the box. The following figure depicts the Enclosure A shipping box contents.
The next figure depicts the Enclosure B shipping box contents.
The Tsunami QuickBridge Quick Install Guide and a Documentation and Software CD also are included in the shipment.
Contact Technical Support regarding any missing or damaged parts.
Proxim recommends that you pre-assemble the radio mounting hardware on the ground to familiarize yourself with the equipment and check for any possible damaged or missing components before mounting the radios. This includes attaching the mounting bracket and loosely attaching the washers, lock washers, and lock nuts to the radios. Installers having prior installation experience may choose to skip this step and proceed with Step 4.
For outdoor installation, the Tsunami QuickBridge package includes a CAT5e cable. This is
a higher grade than a standard cable.
For indoor installation, use either a standard CAT5e or a CAT5 cable when connecting to the PC.
Perform these steps on each radio to pre-assemble the mounting hardware on the radios:
Perform these steps on each radio to pre-assemble the mounting hardware on the radios:
When you initially install the radios, you should configure the radios in the same room. A brief overview of the recommended computer/network configuration follows.
An interface cable with an 8-pin DIN connector and a weather-tight RJ45 cable are supplied in the product package. You also can construct your own interface cable.
The following steps detail how to connect the cables between the radio, power adapter, and your network.
For each radio/power adapter set, perform these steps:
To directly connect the radio to a PC, use a straight-through Ethernet cable between the network interface card in the PC and the RJ45 port on the power adapter.
Use a cross-over Ethernet cable if connecting the power supply adapter to a switch or a hub.
If your installed radio is connected to a switch or a hub, connect your PC to the same switch or hub. Each PC is used to configure and control its associated radio.
Proxim recommends a back-to-back test of the radio pair. Back-to-back testing is a simple way to verify that the radios are fully operational before they are installed.
The process of installation adds several variables that can add to system turn-up delays during troubleshooting (such as antenna alignment, cabling, and path dynamics). Back-to-back testing can eliminate link problems caused by auxiliary equipment, installation, or the radio path, and isolates potential radio hardware problems.
When the equipment is connected as shown in the following figure, a link should be established.
Back-to-Back Test Configuration (Enclosure A Depicted)
The QuickBridge includes configuration software (the QuickBridge Manager), which provides basic setup and operating capabilities. Before installing the software, be sure you have completed Step 4. Connect the Cables.
To install the QuickBridge Manager:
When installation is complete, the following window is displayed; click the Done button to exit the installation program.
Be sure you have completed Step 6. Install the Software.
Before configuring the QuickBridge with the Manager program, you must:
These tasks are covered in the following procedure:
The radios are now ready for any optional configuration steps, and can establish a wireless link.
When selecting a location in which to install the radios, keep the following points in mind:
If necessary, disconnect the cables you used to configure the radios inside, move the radios to their outdoor locations, and then connect them to the network segments you want to bridge.
After you connect each radio to its network segment, make sure you install the configuration software on the two PCs used to control the radios (one PC per radio). Use the configuration software to assign each radio a valid and unique IP address for the network segment to which it is attached.
Be sure to properly weatherproof outdoor connections. See Weatherproofing Connections.
The radio is designed to mount directly to a pole. Using optional mounting brackets, you can
mount the radio to a wall or other flat surface (see Mounting the Radio to a Flat Surface).
To mount the radio directly to a 1 ½-inch or 1 ¾-inch diameter pole, perform the following steps:
The radio is designed to mount directly to a pole. Using optional mounting brackets, you can
mount the radio to a wall or other flat surface (see Mounting the Radio to a Flat Surface).
To mount the radio to a flat surface:
A cellular telephone or two-way radio may be useful for coordinating alignment activities between both ends of the link. Perform a general alignment of the antennas on both ends of the path using binoculars, compass, GPS, or other related tools. You must align the antennas as accurately as possible before passing traffic over the link. This will help in getting the system running more rapidly.
It is critical that you perform antenna alignment on one end of the link at a time, with the other end remaining stationary. In some cases, you may need to perform coarse
alignment using a wide arc in both azimuth and elevation while listening to the audio alignment tone to find the main beam of the opposite end antenna.
For information about using the Receive Signal Quality feature to fine-tune alignment, Aligning Antennas with QuickBridge Manager.
When you finish aligning the radios, tighten down the U-bolt nuts and side bolt nuts to
secure each radio in its aligned position.
This chapter tells you how to:
Tools Required: None.
Equipment Required: PC with 10/100 Ethernet adapter, CAT5 cable w/RJ45
connectors(straight-through)
Required configuration steps include:
See Configuring Settings if you want to:
From the Connection window, click on the Discover Radio(s) button. The QuickBridge Manager program should discover all local radios and display the IP address of each discovered unit in the Radio(s) Available field.
All units have a default IP address assigned at the factory. The Master is set to 192.168.20.56; the Slave is set to 192.168.20.51.
Once you have selected the radio in which you are interested, click the Login button. For first-time configuration, you should login to the Master radio. You may have to clear the ARP table in the PC if there was a previous entry for 192.168.20.56.
The radios are shipped from the factory without preset passwords; click the OK button to log in at the Admin level.
From the Link Status window, review the current status of both ends of the QuickBridge link; in this case, the locally connected radio (Master) and the remote radio (Slave). This window is updated as
changes occur.
Tabs available through the Tsunami QuickBridge Manager appear following the window header on all QuickBridge Manager windows. The following figure shows the tabs before you log on to a particular radio. At this point, you can view only the list of discovered radios and information
about Tsunami QuickBridge Manager.
Once you have logged in, the Connection tab indicates
the IP address of the selected radio being managed by QuickBridge Manager and
the tabs you can access to configure the selected radio.
The selected tab is highlighted; for example, when you click on the Link Status tab, the tabs appear as follows:
LEDs indicating status of the local and wireless links
are displayed at the bottom of all QuickBridge Manager windows.
After you initially configure the radios, you can change the settings defined for each radio. To
change settings:
The Configuration sub-tab contains three buttons: Restart, Refresh, and Save.
The following table indicates whether the value for each field can be configured on the local unit, the remote unit, or both units.

1Changing throughput to 40 Mbps or 60 Mbps can only be accomplished on, and is only valid on, the QuickBridge 60 Master (or Primary) unit. The Slave (or Secondary) assumes the setting of the Master/Primary.
Click the Settings tab and the Admin sub-tab to view or change the default current IP address. This appears in the Network box’s Radio IP Address field. Once a link has been established, you can re-assign the IP address of the remote radio. Any Class A, B, or C address is valid.
Set the local radio’s IP address to an address in the same subnet as the PC’s IP address. If
you change the IP address of the local radio, you must change the IP address of the PC to an IP address in the same subnet as the radio in order to be able to use the Manager program.
To manage the QuickBridge on the other side of a router, configure the subnet mask for the desired subnet and select a unique IP address supported on that subnet.
The Security Key is used to authenticate both radios for authorized point-to-point communication. Before setting the key, be sure the wireless link has been established. Click the Settings
tab and the Admin sub-tab and enter a Security Key in the Security Key(0-16 characters): box. Click Save. With the wireless link established, the Security Key is assigned to both the Local and the Remote unit. The default Security Key is <blank>
(there is no Security Key specified at the factory).
The Security Key can consist of up to 16 alphanumeric characters (a-z, A-Z, 0-9) and is case-sensitive. Non-alphanumeric keys such as * or # are not valid.
Example: ABC6543210jklmnO, or Sunnyvale94085, or BaldMountain888
This key is used to authenticate both radios for authorized point-to-point communication. Radios that do not have the same key cannot communicate with each other and will not establish a wireless link.
The default Security Key is
The default gateway defines the address of the router for your network. The default gateway for each client would point at the router interface for that subnet.
For instance, if you defined a subnet 192.168.1.0 and the IP address for the router
interface on that subnet were 192.168.1.254, then all the clients in that subnet would have their default gateway set for 192.168.1.254.
You can switch between configuration of the Master unit and the Slave unit by clicking the radio button next to Master or Slave.
You can change the throughput setting for the selected radio by clicking the radio button next to one of these selections: 18 Mbps, 34 Mbps, or 54 Mbps. A possible reason for changing this setting is to reduce throughput to increase the range of reception.
In the Ethernet Protocol Support box, you can select IP Only mode or Enhanced Ethernet mode.
Choose IP Only mode when all the bridged traffic is known to be composed of only IP or ARP packets, or protocols that use the 802.3 length field of the Ethernet Header.
Choose Enhanced Ethernet mode when the bridged traffic is known to contain packets with protocols that use 802.2 type fields (in addition to IP or ARP), such as Appletalk, IPX, 3Com 8688, and so on. Note that, with certain traffic loads, performance may be impacted.
Click the Settings tab and the Admin sub-tab to enter or change the Get and Set SNMP Community names in the Set SNMP Community String box.
SNMP delimits management domains by defining communities. Each community is identified by a name, which is an alphanumeric string of up to 255 characters defined by the user.
The Tsunami QuickBridge SNMP agent defines strings of up to 10 characters (case-sensitive, numeric, and alphabetic).
Any SNMP entity (both managed entities and management stations) is assigned a community name by its user. In parallel, the user defines a list of the communities for each SNMP entity authorized to communicate with the entity, as well as the access rights associated with each community (this is the SNMP community name table of the entity).
You can proactively check the performance of the radio by receiving SNMP traps that are sent to a network element manager.
The Frequency Selection consists of two components—a Channel and a Frequency. Throughout this document, these two settings are collectively referred to as the Frequency Plan. The Frequency Plan box lets you choose the Frequency Plan to be used for the selected radio. See Available Frequency Plans for available frequencies. Choose the same Frequency Plan for both radios.
You can leave the Frequency Plan unchanged and proceed with the installation, or you can change the Frequency Plan (now or at any later time). Generally, for a single hop of radios, any of the seven frequency channels (3A, 3B, 3C, 4A, 4B, 4C, or 4D) can be selected. Once a link has been established, changing the frequency plan of either Master radio (when locally connected to the Master) causes the frequency plan of the Slave radio on the other end of the link to change as well.
Click the Settings tab and the Radio sub-tab to reassign the frequency plan. To select a new frequency plan, click on one of the other buttons for the other frequency channel not marked.
Changing Frequency Plans is especially useful when installing multiple QuickBridge units at the same location.
The QuickBridge offers two channel plans, each with non-overlapping frequencies, as defined in the following tables. The 26 dB bandwidth of the RF signal is less than 26 Mhz. Each channel is 20.75 MHz wide at the 3 dB point.
Better alignment (“pointing”) of the antennas results in greater link reliability and robustness. An alignment tool is included in the QuickBridge Manager to assist with this process. It requires at least an approximate alignment of the antennas prior to its execution.
Occasionally, flash upgrades may be made available, offering the ability to enhance some features of your QuickBridge equipment. To upgrade the firmware for your QuickBridge radios:

To verify successful download, login and select the About tab to view software, hardware, and firmware versions.
To view the levels of QuickBridge firmware, hardware, and software in your system, click the About tab. This window also provides information about contacting Proxim Technical Support.
In addition management with the QuickBridge Manager, you also can manage and partially configure a Tsunami QuickBridge using the Simple Network Management Protocol (SNMP). Note that this requires an SNMP manager program, such as HP Openview or Castlerock’s SNMPc.
Tsunami QuickBridge supports several Management Information Base (MIB) files that describe the parameters you can view or configure over SNMP:
Proxim provides these MIB files on the Documentation and Software CD included with each Tsunami QuickBridge unit. You must compile the above MIBs into your SNMP program’s database before you can manage a QuickBridge using SNMP. See the documentation that came with your SNMP manager for instructions about how to compile MIB files.
The Enterprise MIB defines the read and read-write objects that can be viewed or configured using SNMP. These objects correspond to most of the settings and statistics that are available with the other management interfaces. See the Enterprise MIB for more information; the MIB can be opened with any text editor, such as Microsoft Word, Notepad, or Wordpad.
Support for Enterprise and MIB-II traps is included; these are generated when events occur on the QuickBridge radio. Traps can be enabled and disabled individually for customization. (See
the Enterprise MIB description for more detailed information).
Tsunami QuickBridge Manager allows a node moving from one side of a QuickBridge hop to another to re-establish connectivity in a minute or less. Enabling roaming support consists of two steps:
To install WinPcap, follow these steps:
If a previous version of WinPcap is installed, as shown in the following figure (back-level WinPcap 3.0 is shown in a Windows 2000 Add/Remove Programs window), click the Change/Remove button.
Roaming (the -r option) is disabled by default; it can be enabled only through the QuickBridge Manager's command line interface at startup.
To enable roaming, follow these steps:

See the following sections for more detailed troubleshooting information.
This section describes troubleshooting methods for:
When the radios are in service, errors in the data stream can occur. This usually is known to the
operator by either faulty data indications of downstream equipment or external bit error rate testing. The QuickBridge employs a cyclic redundancy check (CRC) on all wireless data, strongly reducing the likelihood of such events. However, there always exists a finite probability of such events.
Some errors are exhibited on downstream data processing equipment or during an external BER test. In
other cases, there may be data errors due to atmospheric conditions (fading), interference, or other reasons. In the case of these types of errors, the following information can be helpful to
troubleshoot the radio link.

The QuickBridge radio offers several distinct non-overlapping frequency channel plans (see Reassigning the Frequency Plan).
Occasionally, interference is caused by the radio being too close to another similar transmitter. Moving the radio or the interfering equipment can reduce or eliminate interference.
Interference countermeasures rely to some extent on the measurement of the received interference level and frequency. Prior to turning up a new hop, a spectrum analyzer can be used to monitor the spectrum at each end to check for possible interfering signals. For more details, see Using a Spectrum Analyzer to Evaluate Potential Interference. ”
Connecting a spectrum analyzer to an external antenna and using “peak hold” on, the spectrum across the receive frequency range of the radio (5725 – 5825 MHz) can be swept and any signals being received at levels above the radio’s specified threshold identified. If potential interfering signals are found, then the frequency plan can be changed to avoid a receive channel that may contain significant interference (see Configuring Settings). For example, you can reduce interference by moving from the 3A plan to
the 4D plan.
Signals outside the receiver frequency range can be ignored; they will not cause interference.
When using a spectrum analyzer for determining the presence of interference, very narrow resolution bandwidth settings must be used to detect signals down to the radio’s threshold (approximately –89 dBm).
The single most effective countermeasure against interference is to maintain “short path” length. This can be achieved by dividing long paths into multiple small paths by cascading hops. Intermediate repeaters can be formed using back-to-back QuickBridge radios.
By definition, short path is a path where fades are extremely rare and signal levels vary by no more than 3 dB during fades. This distance varies with the RF frequency. Typically, a short path is defined as any path length shorter than 5 miles/8 kilometers at 5.8 GHz.
This section provides insight into the planning necessary to prepare your site for your broadband fixed wireless system.
The installation of a wireless network requires much the same basic planning as any wired network. The main difference is that the wireless signal requires some additional planning. This additional planning includes:
Although the technology implemented in this broadband fixed wireless system can make use of multipath signals, reducing the effect of obstructions in the path, the characteristics of the path must be examined carefully. With this knowledge, components and network requirements can be planned correctly for your specific application.
A basic consideration is the physical location of the sites at each end of the link. Because
microwave signals travel in a straight line, a clear line of sight between antennas is necessary. Frequently, however, the locations of the desired links are fixed. When a clear line of sight cannot be achieved, you must plan accordingly.
Other questions to consider include:
The following sections should assist you in determining which information is critical to the site and in making appropriate decisions.
Research any unusual weather conditions that are common to the site location. These conditions
can include excessive amounts of rain, wind velocity, or extreme temperature ranges. If extreme conditions exist that could affect the integrity of the radio link, you should take these
conditions into consideration early in the planning process.
Temperature inversions and stratification also can cause ducting, which can increase the potential for interference between systems that do not normally interfere with each other. Such effects of temperature are noticeable for path links farther than 3 miles.
You must always consider the potential for lightning damage to radio equipment when planning a wireless link. A variety of lightning protection and grounding devices are available for use on buildings, towers, antennas, cables, and equipment, whether located inside or outside the site, that could be damaged by a lightning strike.
Lightning protection requirements are based upon the exposure at the site, the cost of link downtime, and local building and electrical codes. If the link is critical and the site is in an active lightning area, attention to thorough lightning protection and grounding is critical.
To provide effective lightning protection, install antennas in locations that are unlikely to receive direct lightning strikes, or install lightning rods to protect antennas from direct strikes. Makes sure that cables and equipment are properly grounded to provide low-impedance paths for lightning currents. Install surge suppressors on adjacent telephone lines and power lines.
In regions that have extreme lightning occurrences, you should provide additional lightning protection for cables leading to the wireless radio. Place this optional lightning protection at points close to where the cable passes through the bulkhead into the building, as well as near the radio. A grounding screw is provided on the radio.
When the entire interface cable, from the building entrance to the radio, is encased in steel conduit, no surge arrestors are required. Otherwise, each interface cable requires one surge arrestor within two feet of the building entrance.
An important part of planning your broadband fixed wireless system is the avoidance of interference. Interference can be caused by affects outside the system. Good radio frequency (RF) planning can overcome most interference challenges.
Co-channel interference results when another RF link is using the same channel frequency. Adjacent channel interference results when another RF link is using an adjacent channel frequency. In selecting a site, a spectrum analyzer can be used to determine whether any strong signals are present and, if present, determine how close they are to the desired frequency. The further removed from your proposed frequency, the less likely they are to cause a problem.
For point-to-point applications, the narrower the antennas’ beamwidth, the better. QuickBridge
Ethernet Systems use integrated directional antennas that transmit and receive a relatively narrow beamwidth of radio energy, improving system performance by reducing the likelihood that surrounding RF clutter will interfere with reception.
The integral antennas have the following characteristics:
Type: Flat-panel antenna
Even when other licensees are not an issue, all these considerations are still important
to reduce interference between your own adjacent installations. Antennas are tuned to operate on a specific group of frequencies. QuickBridge offers two channel plans that provide a flexible tool for overcoming present and future interference.
Three or four non-overlapping channels (seven total directional channels) can be used to avoid existing traffic in the 5. 8 GHz frequency band. If one part of the 5.8 GHz spectrum is occupied when QuickBridge initially is deployed, another frequency channel can be selected to bypass the
interfering signal. If interference arises after deployment, another frequency channel plan can be selected to “steer around” the impacted channel. Beamwidth and gain have been optimized in this equipment.
When planning antenna placement, it might be necessary to build a free-standing tower for the antenna. Regulations and limitations define the height and location of these towers with respect to airports, runways, and airplane approach paths. These regulations are controlled by the
FAA. In some circumstances, the tower installations must be approved by the FAA, registered with the FCC, or both. To ensure compliance, review the current FCC regulations regarding antenna structures. These regulations (along with examples) are on the FCC website at http://wireless.fcc.gov/antenna/.
To get the most value from a wireless system, path planning is essential. In addition to the fact
that radio signals dissipate as they travel, many other factors affect a microwave signal as it moves through space. All of these must be taken into account, because any obstructions in the
path will attenuate the signal.
A link budget is a rough calculation of all known elements of the link to determine whether the signal will have the proper strength when it reaches the other end of the link. To make this calculation, consider the following information. A signal degrades as it moves through free space. The longer the path, the more loss it experiences. This free-space path loss is one factor in calculating the link viability. Free space path loss is easily calculated for miles or kilometers.
Availability represents the quality of a link. It is the ratio of the time that the link is
available to the total time. This serves as a guide to the service that you can expect, on average, over a period of one year.
The FCC has identified the frequencies from 5.725 to 5.825 GHz as Unlicensed National Information Infrastructure (U-NII). This band can be used by anyone without having to obtain a license. However, you must use radio equipment that is “type approved” by the FCC or local government for use within the specific band. The QuickBridge 60 and QuickBridge 20 are type approved to operate in the U-NII band.
The FCC has identified the frequencies from 5.725 to 5.850 GHz as Industrial, Scientific, and Medical (ISM). This band can be used by anyone without having to obtain a license. However, you must use radio equipment that is “type approved” by the FCC or local government for use within the specific band. The QuickBridge 20 is type approved to operate in the ISM band.
The outdoor placement and height of the QuickBridge radios on a tripod, mast, or pole is critical to the proper operation of the equipment to provide error-free performance.
The wireless path will suffer from poor performance (high bit error rate or even complete outage) if the path has any of the following:
The height of the QuickBridge unit must be sufficiently above the blockage so that definite clear line-of-sight is achieved, as well as clearance in the first Fresnel Zone.
The Fresnel Zone is the shape of the radio beam between the two transmitters that is determined primarily by the distance between the antennas and the frequency of transmission. The Fresnel Zone is not a straight and narrow beam like a laser, but rather “bulged” in the middle like a
football. Any blockage within 60% of this “bulge” would interfere with the performance of the wireless link.
Clearance in the path is defined as consisting of:
The height of each end of the QuickBridge hop must be high enough to ensure:
Distance between 0. 6 x First Earth Total Clearance (minimum)
0.1 mile
3 ft.

For example, for a path that is 3 miles long, the transmitters on each end of the hop must be 18 feet above any obstruction that is in the path. Therefore, if there is a 30-foot building in
the middle of the path, then the two transmitters must be at least 48 ft (30 + 18 ft) above ground. This then dictates the height of the pole or mast; could be a 48 foot mast, or an 8 foot pole on a 4-story building.

All outdoor electronic equipment is susceptible to lightning
damage. Proper grounding to national and
local codes is instrumental in providing human safety. Lightning Protection is used to maximize the
reliability of the electronic system by diverting the excess energy that can be
induced on any transmission lines (data, power) through a series of surge
protection devices. The energy is
dissipated through heat and also diverted to ground.
All Tsunami QuickBridge radio
units have built-in lightning protection on both the power supply lines and the
Ethernet lines. There are TVS diodes
that provide protection to IEC 61000-4-05. Proxim Corporation uses “well-design” practices incorporating these
devices in the Tsunami QuickBridge products.
Lightning, even with the built-in protection, can still
damage outdoor Tsunami equipment. This
can occur for any number of reasons, such as an improperly grounded
installation, or when the amount of transient energy from nearby lightning
exceeds what the devices can handle.
If a Tsunami unit fails due to damage from lightning, the
link is out-of-service until the unit is replaced or repaired. An external, revertive
protection device can provide a higher level of protection and greater
probability of surviving lightning transients without damage to the Tsunami
equipment. If damage does occur, most
likely it is to the lightning protection devices and not the Tsunami
equipment. Remember, even with external
lightening protection, damage can still occur to the Tsunami outdoor units.

1101-TSU Surge Supressor Contact information: Transtector Systems
This is a heavy-duty aluminum, weather-tight enclosure for
outdoor use that serves to protect wireless outdoor units, as well as the
indoor power & Ethernet adapter and connected line equipment inside the
roof penetration. This product can be
used for all CAT 5 cable lengths up to 100 meters from the outdoor wireless
unit to the indoor power & Ethernet adapter. The Polyphaser Data Protector uses
Cascade Technology. This is a
multi-stage technology that is superior to single stage because of high surge
current capacity and fast response time.
The unit is designed to fit in-line onto the outdoor CAT 5e cable, using
two weatherized plug openings for the cable to enter and exit. The existing cable is cut, dressed, and
reconnected onto two sets of 8 screw terminals inside the Data Protector. This outdoor-use, molded plastic, weather-tight enclosure is
a surge suppressor designed to protect the QuickBridge
II unit from lightning damage. This
product can be used for CAT 5 cable lengths up to 50 meters from the outdoor
wireless unit to indoor power & Ethernet adapter. The 1101-TSU uses silicon avalanche suppression diodes
(SASD) to provide lower voltage protection level (VPL). This technology provides a superior
protection level over traditional gas tube type devices. The unit is designed to fit onto a CAT 5
cable in a pass-through configuration.
The input and output connections can be made at two sets of 8-screw
terminals, or two 8-pin DIN style connectors.
This arrangement allows the installation of the connectorized
CAT 5e cable directly into the Surge Suppressor, or with a cut cable. The lightning protection units recommended are designed to
be installed in-line onto the CAT 5e cable that connects the outdoor QuickBridge unit to the indoor power adapter. The lightning protection device has a Surge
(cable-facing) side, and an Equipment
(equipment-facing) side. The Equipment
side faces the outdoor QuickBridge unit or the indoor
power & Ethernet adapter. The Surge
side faces the long length of cable; when installing two lightning protection
units, each unit’s Surge side face one another. See pin-out information for each unit in “Protection Unit
Specifications” for connecting the cable to the protection device. At least one unit should be installed near every
outdoor QuickBridge unit. General guidelines are:Introduction

Note: Back-to-back testing must be performed to verify a radio problem before returning any radio to Proxim for repair.
Step 6. Install the Software
Note:  Install a copy of the QuickBridge Manager on any PC from which you want to manage a radio.
Step 7. Setup for Configuration
Notes:
Note: The QuickBridge Manager program can run on two PCs connected to both ends of the link without interfering with one another.
Step 8. Mount the Radio Outdoors
Selecting a Location
WARNING! Do not co-locate two hops on the same side of the building or on the same pole.
Mounting the Radio to a Pole, Enclosure A
Note: If it is not practical to slide the pole mounting assembly through
the pole (for example, if the pole is too tall), disassemble the U-bolts, mounting bracket, and side screws and reassemble them around the pole. See Step 3. Pre-Assemble Hardware for information about assembling these components.
Mounting the Radio to a Pole, Enclosure B
Mounting the Radio to a Flat Surface
Note: To ensure proper grounding, use the hole on the back of each radio and the provided grounding screws to attach a ground wire to each radio.Use proper wire
grounding techniques in accordance with your local electrical codes. You also can mount the radios on tall, multi-section poles with guide wires. For these types of installations, you should consult professionals with experience.
Step 9. Align the Radios
Discovering and Configuring the QuickBridge Radios
Step 1: Establishing a Connection
Note: Other radios located elsewhere on your network are reachable, but only those discovered through the Ethernet connection are discovered automatically.
Note: If you want to connect to a different radio, you can enter the IP address and click the Login button for the Manager to connect to the specified radio.
Step 2: Logging In
Note: For first-time configuration, you should login to the Master radio. You may have to clear the ARP table in the PC if there was a previous entry for 192.168.20.56.
Notes:
Step 3: Reviewing the Master Unit's Status
Note: When the link has not been established to the remote unit, the remote status is shaded gray and shows incorrect status. After the link is established, the correct status is reported.

Aligning Antennas with the QuickBridge Manager
CAUTION: Put only one unit into “pointing mode” at a time.
Note: Before a link is established, the Slave indicates an RSL immediately,
whereas the Master must complete the RF link before showing the RSL (up to 2 minutes). Therefore, Proxim recommends starting antenna alignment from the Slave.
CAUTION! If the link is already established when you enter the Antenna Pointing Program, traffic is interrupted.
Note: There is a slight delay (a few seconds) before the Receive Signal Quality bar moves to indicate adjustments to the antennas and the Receive Signal Level.
Upgrading Your System’s Firmware (Upgrade Tab)
CAUTION! When upgrading firmware from one side of the link, the remote side should always be upgraded first. Failure to do so may render the link inoperable, requiring the remote unit to be upgraded locally.

1The RTN pins in the ALPU-TSU are floating ground. The DC connection (+24 VDC and Gnd) will be unaffected if the ORANGE (or BLUE depending upon the color code on pin 1 of the RJ45), or the WHITE/ORANGE i(or White/Blue) wire is connected to the RTN pin.
For additional information, go to www.transtector.com
The color code of the Ethernet cable used between the power supply and
the radio depends upon the particular QuickBridge radio. For example, the color code of the Ethernet
cable used between the power supply and the radio has been changed to the
standard EIA 568B wiring color code. See the illustration at the bottom of
the next page.
Normally this does not present a problem since the cable is wired the
same end-for-end; just the colors have changed. When using a lightning
protector, however, the color code of the cable must be noted to make sure that
the lightning protection is connected properly. Incorrect wiring can
cause damage to the lightning protector. Here are the two different color
codes.

The color code that a cable is using can be identified by either looking at the color of the wire in pin one of the RJ45 connector (the pin on the left with the tab facing down and the cable coming towards you). If the wire in pin 1 is Green, then you have the original color code, if the wire is White / Orange then you have an EIA 568B wired cable.
Alternatively, if you do not have
access to the RJ45 (for installed systems), you may reference the part number
and revision label on the cable that is usually near the DIN connector.
Refer to the following table to determine which color code cable you have based
on the cable.

The QuickBridge provides ways to prevent unauthorized users from communicating with the QuickBridge unit. You can password protect the system to prevent unauthorized users from accessing the system. Also, you can use the Link Security Key to scramble the transmitted signal, preventing unauthorized units from detecting the signal.
The QuickBridge provides two levels of password protection:
The default password is <blank>. By default, password protection is turned off. Password protection for either password level (user or admin) can be turned on and off.
Passwords can be from 1 to 16 characters; any combination of alphanumeric characters are allowed.
To define the password for either access level from the QuickBridge Manager:
Upon successful login, the Link Status window for the selected radio is displayed.
To turn off password protection, reset both passwords to <blank>.
Do this by returning to the Security window and entering the current password while leaving the two new password entries blank (for both the User and Admin access levels).
If a password has been specified for the access level you desire, you must log in to the system with the appropriate password.
Wireless transmissions on the QuickBridge employ PN scrambling whereby all emissions are "shuffled." The shuffling method is uniquely determined by the 16-character security key so that the receiving device can correctly "un-shuffle" the transmission. With a mismatched security key, the shuffled transmissions are unusable to the device attempting to receive the signal.
The 16-character Security Key is user-defined using the QuickBridge Manager program. The two keys, set for both the Master and Slave units, must match before a link can be established. The ID code is made up of 0-9, a-z, and A-Z characters.
In addition, the two units must match frequency plans and one must be designated a “Slave” and the other must be “Master”. Two Slaves cannot talk to one another, and two Masters cannot talk to another.
