Section 1 System Description TRACER 6420 System Manual 12 Copyright © 2005 ADTRAN, Inc. 612806420L1-1A1. SYSTEM OVERVIEWThe TRACER 6420 provides license-free scalable connectivity for service providers and corporate networks. These radios feature two modular network interface ports that can accommodate various combinations of T1 and Ethernet option cards up to 8xT1 (16.384 Mbps). This flexibility provides customized TDM and packet solutions for voice and data applications in a single platform. The TRACER 6420 radios provide carrier class point-to-point connectivity up to thirty miles in the 5.8 GHz license-free Industrial, Science, and Medical (ISM) band. Complete network management is supported via SNMP, Telnet access, and a VT100 craft port. SNMP traps are implemented for all RF link and T1/Ethernet alarm conditions, enabling remote installations to report outages without requiring a truck roll to diagnose problems. Version 2 standard MIBs are supported for all interface cards, while an enterprise-specific MIB is provided for radio functionality. Triple-DES security provides additional protection from unauthorized access without requiring any additional external security appliances. Encryption can also be disabled altogether. Future upgrades and enhancements can be added through FLASH firmware downloads via TFTP (on the Ethernet interface) or XMODEM on the craft port.Receive sensitivity is optimized through the use of extensive forward error correction and high-performance receiver design techniques. Dynamic receive sensitivity allows the user to increase receiver performance by decreasing the delivered bandwidth. This feature maximizes link performance by customizing the delivered bandwidth to the specific needs of the installation. Three software selectable channel plans are supported to simplify frequency coordination at co-located sites. Channel plans are easily changed via any of the software management interfaces without the added expense of hardware upgrades or spare filter assemblies.TRACER wireless solutions maximize equipment density through the combination of compact size (only 1U rack space required), low power consumption, and high thermal transfer. TRACER systems can be deployed at twice the density of other available wireless products.2. FEATURES AND BENEFITSThe following is a brief list of the TRACER 6420 features and benefits:Configuration and Management• Easy to use VT100 control port (RS-232 interface) for configuration and monitoring• Remote configuration of both ends of the wireless link, from each end of the linkOperational• No license required per FCC Rules Part 15.247• Frequency: 5.725 to 5.850 GHz• Point-to-point, up to 30 miles• 1-U high unit for easy rack-mountingAvailable Interface Modules• Quad T1 Module (P/N 1280040L1)• Quad Ethernet Switch Module (P/N 1280050L1)

Section 2 Microwave Path Engineering Basics TRACER 6420 System Manual 14 Copyright © 2005 ADTRAN, Inc. 612806420L1-1A1. LINE-OF-SIGHTThe TRACER 6420 system is designed for operation in the license-free 5.725 GHz to 5.850 GHz industrial, scientific, and medical (ISM) band. Radio wave propagation in this band exhibits microwave characteristics which are ideally suited for point-to-point, line-of-sight communications. Line-of-sight requires that the transmitting antenna and receiving antenna are able to “see” each other, and that the straight-line path between the two antennas is free of obstructions such as buildings, trees, mountains, and in longer paths, even the curvature of the earth. For maximum signal strength, the area around the visual line-of-sight where microwave signals reflect (Fresnel zone) must also be free of obstructions. Fresnel zones are discussed in more detail on page 21.Terminology2. DECIBELSUnderstanding the decibel (dB) format is key when discussing microwave path engineering because the received signal power is often expressed in decibel format. In general, any quantity can be expressed in decibels. If the quantity x is a power level (in Watts), the decibel equivalent is defined asIf the quantity x is referenced to a milliwatt (mW), then the decibel-milliwatt (dBm) is used instead of a generic decibel.Using the decibel format simplifies power calculations by reducing multiplication and division operations into addition and subtraction operations.3. CALCULATING THE FADE MARGINThe fade margin (F ) is a value in decibels (dB) that represents the amount of signal reduction that can be tolerated before the link exceeds the specified bit error rate (BER). Fade margin is simply the difference between the available signal power at the receiver (PR ) and the receiver sensitivity (Psens ). Point-to-Point Wireless communication from a single site to another individual site. Contrast with point-to-multipoint.Line-of-Sight An unobstructed, direct path exists between the transmitting and the receiving antennas.It is imperative to determine whether the proposed microwave path is suitable (at a minimum) for ideal, nondistorted signals before attempting installation.xdB 10 log10 x()⋅=(dB)xdBm 10 log10x1mW-------------⎝⎠⎛⎞⋅=(dBm)FPRPsens–=(dB)= PT + GT + GR - L - LP - Psens

For most applications, 20 to 30 dB of fade margin should ensure a reliable link. The following sections further discuss the necessary power calculations and their components.4. RECEIVER POWERThe viability of a particular microwave path is determined by the power of the transmitted microwave signal, the transmit and receive antenna gain, distance, and accumulated system losses (such as RF coaxial cable losses and path loss).The equation relating received signal power to the other microwave parameters isor (in decibel notation)where the variables in the equations are defined asPRreceived power (dBm) PTtransmitted power (adjustable up to 20 dBm maximum) GTtransmit antenna gain (decibels referenced to an isotropic source – dBi) GRreceive antenna gain (dBi) λcarrier wavelength (meters) dpath distance (meters) Lother losses (RF coaxial cable, etc. – dB) LPpath loss (dB)When using decibel notation, all quantities must be individually converted to decibels prior to performing addition and subtraction.PRPTGTGRλ24π()2d2L------------------------------=(Watts, W)(decibels referenced to a milliwatt, dBm)PR = PT + GT + GR - L - LP

Example Microwave Path with ParametersThe following sections further discuss the power budget analysis and its components.Antenna GainActual transmit and receive antenna gain values depend strictly upon the physical characteristics of the antennas installed for each link. In other words, the size of the dish determines the antenna gain. Using a parabolic dish antenna results in the best performance. Antenna gains are specified in terms of decibels of gain referenced to an isotropic source (dBi). An isotropic source is a hypothetical antenna having equal radiation in all directions. Typical antenna gains are listed in Table 1; however, dish manufacturers can provide gains for specific types of antennas.Transmitted Power (PT)The FCC specifies the maximum transmitter power used for antennae of a given gain. FCC Rules (Part 15, Subpart 247) allow for a maximum transmit power of 1 Watt (30 dBm). Since the TRACER 6420 maximum transmit power is 100 milliwatts, there is no reduction in transmitter output power required.Table 1.

TRACER 6420 System Manual Section 2 Microwave Path Engineering Basics612806420L1-1A Copyright © 2005 ADTRAN, Inc. 17Carrier Wavelength (λ)The carrier wavelength is the physical wavelength of the main RF carrier being used for communication, and is usually approximated at the center frequency of the band (which is 5787.5 MHz for the TRACER 6420). The carrier wavelength calculations follow:λ = c / f (meters)where c = speed of light (in meters) f = frequency (in Hz)resulting in the following carrier wavelength:λ = 3.00 x 108 / 5787.5 x 10 5 = 0.0518 m or 5.18 cmPath Distance (d)The path distance is simply the physical distance between the transmit and receive antennas. For the TRACER 6420, these distances can range up to 30 miles. System Losses (L)System losses are defined by RF coaxial cable loss, connector losses, and losses added from any additional lightning protection devices for the power budget analysis. Coaxial cable is required to attach the TRACER 6420 to the antenna. The length of the cable varies from a few feet to hundreds of feet, depending upon your application and the proximity of the TRACER 6420 to the antenna. Various grades of coaxial cable will work sufficiently well for connecting the TRACER 6420 unit to the antenna. A low-loss coaxial cable will minimize cable losses.One end of the coaxial cable requires an N-type male connector (plug) to mate with the TRACER 6420 unit. The other end of the coaxial cable requires a connector compatible with the antenna chosen for the installation (usually an N-type male connector). Additionally, ADTRAN recommends that the outdoor connector on the coaxial cable be weatherproofed to prevent corrosion and electrical shorting.In areas where lightning strikes are frequent, a lightning arrestor should be installed directly on the antenna coaxial cable. Installing lightning arrestors helps protect the RF electronics (including the TRACER 6420 unit) in the downstream path from damaging voltages and currents.
Section 2 Microwave Path Engineering Basics TRACER 6420 System Manual 18 Copyright © 2005 ADTRAN, Inc. 612806420L1-1ATable 2 gives typical loss figures for some of the more common coaxial cable types (per 100 feet).Path Loss (LP)Path loss is the estimated attenuation between the transmit and receive antennas caused by signal separation and scattering. The path loss is considered basic transmission loss over the microwave link. The following expression calculates path loss:where fcarrier frequency (Hz) λcarrier wavelength (c / f) (meters) dpath distance (meters) cspeed of light, free-space (meters)orwhere d is expressed in miles and f in GHzPath loss, as shown here, increases rapidly as either the path length increases or the carrier wavelength decreases (which happens as the carrier frequency increases). Therefore, longer microwave paths naturally experience more path loss than shorter paths. Likewise, higher frequency microwave communication experiences more path loss than lower frequency microwave communication.Table 2.

Values not listed in the table can be interpolated from those listed.5. RECEIVER SENSITIVITYReceiver sensitivity is a value expressed in decibels referenced to one milliwatt (dBm) that corresponds to the minimum amount of signal power needed at the receiver to achieve a given bit error rate (BER). Receiver sensitivity is usually a negative number of decibels, and smaller receiver sensitivity (higher quantity negative number) is better for a given BER. Several factors affect receiver sensitivity, including the data bandwidth of the wireless link and the amount of additional signal degradation introduced in the receiver electronics.Receiver sensitivity of the TRACER 6420 is dynamic as a function of the desired bandwidth; receiver sensitivity improves as delivered bandwidth decreases. TRACER bandwidth is provided in the form of 8 channels available for mapping to the support modules. For T1 Modules, each channel mapped represents a single T1 interface. For Quad Ethernet Switch Modules, each channel mapped represents 2 Mb of switch data delivered to the module. In situations where 8-channel connectivity is not required, the delivered bandwidth can be decreased to 4 or 2 channels, and the receiver sensitivity will be improved as follows:Table 3.

Changing the TRACER 6420 band plan does not require additional components, or opening of the radio. See > RF Link Configuration > RF Band Plan on page 53 for additional details.

ANTENNA INFORMATIONThe overall wireless system is directly affected by the antenna selection and installation, discussed in the following sections.Antenna AlignmentWith line-of-sight microwave communications, optimum system performance requires that the transmitting and receiving antennas are properly aligned. This ensures maximum received signal power at each receiver. Antenna alignment must be achieved in both azimuth (along a horizontal plane) and elevation (along a vertical plane). By ensuring maximum received signal strength, a received signal strength indicator (RSSI) helps the equipment installer to determine when alignment is maximized. TRACER RSSI Test PointsRSSI for the TRACER 6420 system is provided through the VT100 terminal menus accessed through the RS-232 interface, and it is presented as a series of bars indicating signal strength. More bars means more RSSI, which ensures greater received signal strength and better link performance.If both the local and remote end of the system are operational, the remote TRACER 6420 receive power can be viewed from the local TRACER 6420 VT100 terminal menu interface.An RSSI test point, located on the front panel, provides a DC voltage level (relative to the GND test point) that corresponds to the amount of signal being received from the far end's transmitter. The voltage at this test point can vary from approximately 0 to 5 VDC. An RSSI calibration sheet is shipped with the system to provide the installer a cross-reference between actual received signal level (in dBm) and RSSI voltage. This sheet is useful for verifying link budget calculations and ensuring proper equipment installation.Antenna Beam PatternsDirectly related to the subject of antenna alignment is the topic of antenna beam patterns. Antennas used with the TRACER 6420 system have a particular beam shape, determined in part by the physical construction and geometry of the antenna. The antenna beam patterns are characterized by a dominant main lobe, which is the preferred lobe to use for point-to-point communications, and several side lobes, as shown in Figure 2. When setting up a microwave link, antenna alignment is nothing more than steering the main lobes of both antennas until the main lobe of one transmitter is centered on the receiving element of the receiving antenna.Verify the antenna installation meets all regulations specified in the National Electric Code (NEC) Article 810.
TRACER 6420 System Manual Section 2 Microwave Path Engineering Basics612806420L1-1A Copyright © 2005 ADTRAN, Inc. 21Figure 2. Typical Antenna Beam PatternAntennas are also designed to radiate RF energy efficiently for a specific range of frequencies. Please consult the data sheet for your particular antenna make and model to ensure that it is specified to operate in the 5725 MHz to 5850 MHz frequency band for the TRACER 6420 system.Fresnel Zones, Earth Curvature, and Antenna HeightsFresnel zones correspond to regions in the microwave path where reflections of the intended signal occur and combine in both constructive and destructive manners with the main signal, thereby either enhancing or reducing the net power at the receiver.In general, the odd numbered Fresnel zones (1, 3, 5, ...) add constructively at the receiver, while the even numbered Fresnel zones (2, 4, 6, ...) add destructively at the receiver.The first Fresnel zone corresponds to the main lobe, 60% of which must be free of physical obstructions for the path calculations to be valid. Since the main lobe contains the vast majority of the microwave energy, this zone is typically used to determine proper antenna heights when placing antennas on towers or buildings.The curvature of the Earth becomes a legitimate obstruction for path lengths of 7 miles or greater, and must also be accounted for when determining minimum antenna heights.The aggregate expression for minimum antenna height that incorporates both the 60% first Fresnel zone and the Earth’s curvature is given bywhere f is in GHz and d is in miles.main lobeside lobesh72.1d4f-----0.125d2+= (feet)

OTHER CONSIDERATIONSPath AvailabilityThe path availability of a wireless link is a metric that expresses the fractional amount of time a link is available over some fixed amount of time, and depends on several factors. Path availability is expressed aswhere the parameters areaterrain factor bclimate factor fcarrier frequency (GHz) dpath length (miles) Ffade margin (dB)Terrain Factor (a)The terrain factor is a quantity that compensates the link availability for different types of terrain. Generally speaking, the smoother an area's terrain is, the less availability a wireless link running over that terrain will have, primarily due to multipath reflections. In contrast, secondary microwave signals will be randomly dispersed over rough terrain and will not interfere with the main signal lobe as badly as in the smooth terrain case. The terrain factor values normally used are listed below:Climate Factor (b)The climate factor is a quantity that compensates the link availability for different types of climates (weather). In general, microwave links operating in areas with high humidity will have less availability than those in arid areas, primarily because water is a dispersive mechanism to microwave energy and causes the main signal lobe to refract and disperse away from the receiver location. The climate factor values normally used are listed below:Terrain Terrain Factor DescriptionSmooth 4water, flat desertAverage 1moderate roughnessMountainous 1/4 very rough, mountainousClimate Climate Factor DescriptionVery Dry 1/8 desert regionsTemperate 1/4 mainland, interior regionHumid 1/2 humid and coastal regionsA12.5106–×()abfd310 F10⁄–()–[]100%×=(%)

Section 3 Engineering Guidelines TRACER 6420 System Manual 30 Copyright © 2005 ADTRAN, Inc. 612806420L1-1ADC Power Connection (Plug-In Terminal Block)The TRACER 6420 can operate from a supply between 21 and 60 VDC, with either polarity referenced to ground, and consumes less than 25 W. Power supplies should be able to provide up to 25 W at the selected voltage. Current required (in Amps) is determined by dividing the power consumed (in Watts) by the applied voltage (in Volts). For example, at 48 V, TRACER 6420 would draw approximately 0.52A (25 W/48 V).FuseThe fuse holder, accessible from the rear panel of the TRACER 6420, accepts a generic 2 A, 250 V, 2-inch slow-blo fuse.Alarm Contacts (Plug-In Terminal Block)An RF link down condition is indicated with both normally open (NO) and normally closed (NC) alarm contacts on the rear panel of the TRACER 6420 system. In normal operation, the NC contact is electrically connected to the common contact (COM) and the NO contact is isolated. When the RF link drops, the NC contact becomes isolated and the NO is electrically connected to COM. This allows RF down conditions to be reported to external alarm monitoring systems. Table 9 provides the Alarm Contact pinout.Antenna Interface (N-Type connector)The ANTENNA interface (N-Type connector) connects to the customer-supplied antenna using standard antenna feedline cable.

CHANNEL SELECTIONThe FCC has allocated 125 MHz of spectrum in the 5.8 GHz band where the TRACER 6420 operates. Figure 1 illustrates the bandwidth division. Figure 1. 5.8 GHz Bandwidth DivisionTo designate the utilization of the ISM bandwidth, there are two different channel plans, labeled A and B. The letter of each channel plan setting is preset by the factory and refers to the physical configuration of the diplexer filter inside the chassis. Each channel is then divided into three band plans (1, 2 or 3). The band plans must be the same for the local and remote TRACER 6420. For example, the transmitter at one end of the link will transmit in band plan 1 of channel A (the lower portion of the spectrum) and receive in band plan 1 of channel B (the upper portion). Consequently, the receiver at the other end should receive in band plan 1 of channel A (the lower portion) and transmit in band plan 1 of channel B (the upper portion).The letter of the channel plan (A or B) must be different on both ends and the number of the band plan (1, 2, or 3) must be the same on both ends. The default band plan configuration for the TRACER 6420 is band plan 1.The channel plan (A or B) of the unit may be changed in the field, if necessary, by rewiring the internal diplexer. Contact Technical Support for more information on this procedure.Channel A57445725 5787 58505747 5751MHz MHzBand plan 3Band plan 2Band plan 1Channel B5824 5827 5831Band plan 3Band plan 2Band plan 1

The status of the received radio link is indicated as RF UP or RF DOWN for each direction. This RF status display corresponds to the RF DWN LED on the front of the unit.D. Remote System StatusThe right portion of the TRACER 6420 System Status menu page reports the status of the remote TRACER 6420 (the system across the wireless link from the active terminal). If the RF link is down in either direction, DATA NOT AVAILABLE is displayed in place of the remote system status information.E. Local System StatusThe left portion of the TRACER 6420 System Status menu page reports the status of the local TRACER 6420 (the system where the active terminal is attached). F. Frequency PlanDisplays the frequency plan (A or B) for the TRACER 6420 unit. For an operational TRACER 6420 system, you should have one A and one B frequency plan.G. Rx QualityDisplays an indicator of receive signal quality that is not necessarily related to receive signal level (for both the local and remote units) using a series of symbols (#).

Each channel is divided into three band plans (1, 2, or 3). Both local and remote TRACER 6420 must be configured with the same band plan (1, 2, or 3) but different channel plans (Plan A or Plan B). For example, the transmitter at one end of the link will transmit in band plan 1 of channel A (the lower portion of the spectrum) and receive in band plan 1 of channel B (the upper portion). Consequently, the receiver at the other end should receive in band plan 1 of channel A (the lower portion) and transmit in band plan 1 of channel B (the upper portion). (Refer to Figure 6 for the division.) The TRACER 6420 comes factory programmed with RF band plan set to Band 1.Figure 6. 5.8 GHz Bandwidth Division> RF LINK CONFIGURATION > LINK ENCRYPTIONThe TRACER 6420 provides Triple-DES (3DES) encryption of the data passed over the RF Link. When LINK ENCRYPTION is set to ENABLED, the TRACER 6420 sequentially applies the three keys entered in the SUBKEY 0, 1, and 2 fields to each 64-bit block of data transmitted over the RF link. The remote TRACER 6420 uses the same keys to decrypt each block.

Section 8 Troubleshooting Guide TRACER 6420 System Manual 104 Copyright © 2005 ADTRAN, Inc. 612806420L1-1A1. OVERVIEWThis troubleshooting guide provides recommended actions for various conditions of the TRACER 6420 system. The status LEDs (located on the front panel of the unit) provide information to help determine the necessary troubleshooting action. This guide contains recommended actions for resolving possible problems indicated by the status LEDs.2. LED INDICATORSPWR LEDIf the PWR LED is not ON and solid green, the TRACER 6420 is not receiving adequate DC power. Recommended Actions:1. Verify that the power source is delivering between 21 and 60 VDC.2. Check the polarity of the power connection (referenced to ground) of both the TRACER 6420 unit and the power source.3. Check the internal fuse. The fuse is accessed from the rear panel of the unit. If this fuse is open, replace with a 2 A, 250 V (2-inch) slow-blo fuse.TST LEDThe TST LED will flash once (amber) during power-up to indicate a self-test is in progress. If the TST LED is flashing or remains ON after 10 seconds, the TRACER 6420 unit has failed the self-test. This is an internal failure, and technical support should be contacted.RF DWN LEDIf the RF DWN LED is ON (solid red), there is a problem with the RF receive path from the remote TRACER 6420.Recommended Actions:1. Verify that one end of the link is configured as Plan A and the other end as Plan B.2. Measure the RSSI voltage and consult the RSSI calibration sheet included with the unit. If the voltage level corresponds to a received signal power level that agrees with the calculated receive signal level, proceed with Step 7.3. Check the RF coaxial cable connection.4. Verify that the antenna polarization is the same at both ends of the RF signal transmit and receive path.5. Verify the RF signal path is clear.6. Check the integrity of the lightning arrestors.7. Check for possible interference at both ends of the link. If necessary, change polarization and/or band plans at both ends.
TRACER 6420 System Manual Section 8 Troubleshooting Guide612806420L1-1A Copyright © 2005 ADTRAN, Inc. 105RF LOW LEDIf the RF LOW LED is ON (solid red), the received signal is approaching 0 V of RSSI. This condition is typically indicative of a path or installation problem.Recommended Actions:1. Verify the far-end transmitter power setting is the value that the link planning budget allows.2. Check all coaxial cable connectors for solid connections. Check for water and corrosion around any of the connectors. If water is apparent in the coaxial connectors, replace the coaxial cable and the connectors, making sure to properly weatherproof the replacements.3. Verify the RF signal path by verifying the antenna alignment.4. Check the integrity of lightning arrestors.T1 Interface Alarm LEDsIf the ALARM LED is ON (solid red), it is an indication that the TRACER 6420 is detecting an active T1 alarm. To identify the T1 interface in alarm and the specific alarm present, display the T1(X) STATUS screens and check the T1(X) INTERFACE ALARMS field.Recommended Actions:1. Display the T1(X) STATUS screen and check the T1(X) INTERFACE ALARM field to identify the active alarm. 2. Follow the steps below for the appropriate alarm.LOS Alarm (Red Alarm)LOS ALARM is an indication that the TRACER 6420 may be unable to detect a viable T1 received signal from the connected T1 equipment. This error may be due to a degraded signal or no signal, or may be caused by improper framing.Recommended Actions:1. Verify that the T1 cable is connected to the T1 interface on the TRACER 6420.2. Verify the connections at the opposite end of the T1 cable.3. Verify that the framing mode (D4 or ESF) is the same for both the TRACER 6420 and the T1 equipment.Yellow AlarmA Yellow Alarm is generated by the attached equipment. When the attached equipment’s T1 interface is in Red Alarm, the TRACER 6420 generates a Yellow Alarm.Recommended Actions:1. Follow the troubleshooting steps for Red Alarm, but do so at the attached equipment.Blue Alarm A remote alarm (alarm indication signal or AIS) is generated by the attached equipment. The root cause must be determined at the attached equipment. A typical cause of a blue alarm is a lack of input to a CSU.Recommended Actions:1. Verify the input to any attached data equipment.
Section 8 Troubleshooting Guide TRACER 6420 System Manual 106 Copyright © 2005 ADTRAN, Inc. 612806420L1-1ABPVBipolar violations (BPVs) indicate an improper configuration or faulty wiring.Recommended Actions:1. Verify the TRACER 6420 unit and the attached equipment are configured for the same line coding (B8ZS or AMI).2. Verify the cable connections for the T1 interface are solid.LAN LEDsIf the LAN LED is OFF, the TRACER 6420 is not able to detect an active Ethernet link on the particular 10/100BaseT/TX interface. Recommended Actions:1. Check all Ethernet cable connections to verify they are properly plugged in (making sure the tab on the connector snaps into place). 2. Connect the 10/100BaseT/TX interface to a “known good” Ethernet port to verify the TRACER port is functioning properly.3. Try another Ethernet cable.3. RF ERRORSRF errors can range from a nonviable microwave path to loose RF connectors.Nonviable path conditions could be caused by physical obstructions such as buildings, mountainous terrain, trees, etc., as well as other physical limitations such as excessive path distances and in-band RF interference. These types of errors are remedied by performing a detailed line-of-site microwave path study to determine whether a microwave link is feasible for the terrain and environment under consideration.If after performing a microwave path study the system is still not operational, ensure that the antennas are properly aligned. Note that alignment must be achieved in both elevation and azimuth for optimal link performance. The TRACER 6420 can be used to aid in antenna alignment by looking at the RX POWER “fuel gauge” on the System Status or System Option menu pages or by measuring the DC voltage (relative to ground) at the RSSI front panel test jack. Optimal antenna alignment is achieved by peaking the front panel RSSI voltage or the RX POWER “fuel gauge” on the TRACER 6420 terminal display. Consult the ADTRAN TRACER Data Sheet included with the unit to verify that the actual receive signal level agrees with the calculated receive signal.An RSSI test point, located on the front panel, provides a DC voltage level (relative to the GND test point) that corresponds to the amount of signal being received from the far end's transmitter. The voltage at this test point can vary from approximately 0 to 5 VDC. An RSSI calibration sheet is shipped with the system to provide the installer a cross-reference between actual received signal level (in dBm) and RSSI voltage. This sheet is useful for verifying link budget calculations and ensuring proper equipment installation.4. STEP-BY-STEP TROUBLESHOOTINGThe logical troubleshooting flow presented in this section can be used to set up your TRACER 6420 system, and also to diagnose a previously installed system. Please contact Technical Support at any stage during installation and/or troubleshooting if you require assistance.
TRACER 6420 System Manual Section 8 Troubleshooting Guide612806420L1-1A Copyright © 2005 ADTRAN, Inc. 1075. INSTALLING/TROUBLESHOOTING THE TRACER HARDWARE1. Perform a detailed path profile and link budget for each TRACER 6420 microwave link. A thorough path study can be used to estimate signal power budgets, estimate fade margins at each receiver, identify potential line-of-site obstacles, properly size antenna dishes, and determine minimum antenna dish heights above the earth.2. Set up all of the TRACER 6420 hardware on a workbench. The actual cables used in the permanent installation should be used in the workbench setup. A rigorous workbench “simulation” of the link will help alleviate and avoid time-consuming errors.3. Examine the PLAN A and PLAN B LEDs on the front panel of each unit. These LEDs indicate the frequency plan for each TRACER 6420 unit. Each TRACER link must have a Plan A radio on one side and a Plan B radio on the other.4. Attach the RF coaxial cables to be used in the permanent installation to the N-type connectors on the back of the TRACER 6420 unit. Attach the other end of the coaxial cable(s) to an RF power meter or spectrum analyzer, if either is available. The power measured by the meter/analyzer will be the RF power available at the input of the antenna. The TRACER 6420 unit is programmed at the factory to output approximately 100 mW (20 dBm) of RF power. The actual power level measured by the meter/analyzer will be less than 100 mW due to RF losses through the coaxial cable, and is a function of the cable type and length being used. In any event, the power level at the output of the coaxial cable should be a significant fraction of 100 mW. A power meter/analyzer reading that is not on the order of at least tens-of-milliwatts could be an indication of unsuitable RF cable or faulty or unreasonably long coaxial cable, or a combination of these factors.5. Resolve all RF coaxial cabling errors before proceeding.6. Attach the RF coaxial cables to a high-quality attenuator, if possible. If you do not have an attenuator, attach the coaxial cables to the antennas to be used in the permanent installation. If the installation antennas are not available, small, inexpensive dipole or patch antennas can be used for verification purposes. If an adjustable attenuator is being used, dial in the amount of attenuation that corresponds to the path loss value expected for the microwave link in which the TRACER hardware will be installed. The path loss value can be calculated from a knowledge of the path length, or provided by a path study. Remember to subtract both antenna gain values from the attenuator level if these values have not already been accounted for.7. After setting up the RF pieces, examine the RF DOWN LED on the front panel of each TRACER 6420 unit. If the RF DOWN LED is illuminated (red), the corresponding TRACER 6420 is not receiving a suitable RF signal from the other TRACER 6420 unit. In this case, the receiving TRACER 6420 is either receiving a very weak signal or no signal at all. If the RF DOWN LED is not illuminated, then the TRACER 6420 units are receiving a suitable RF signal. Suitable RF power levels for low error rate communication will range from -30 dBm to -88 dBm measured at the N-type connector input on the TRACER 6420 unit.8. Resolve any signal level issues before proceeding.9. Examine the RF LOW LED on the front panel of each TRACER 6420. If this LED is illuminated, then the TRACER 6420 is receiving a relatively weak signal; however, if the RF DOWN LED is not illuminated, then the received signal is being suitably processed by the TRACER 6420 system. If you are receiving a weak signal (RF LOW is ON), please verify that the weak signal is not being caused by a faulty cable, an insufficiently tightened cable, or some other installation-related problem. Also, make sure an unreasonably large attenuation value has not been selected if you are using an attenuator on a workbench setup.
Section 8 Troubleshooting Guide TRACER 6420 System Manual 108 Copyright © 2005 ADTRAN, Inc. 612806420L1-1AUse the tables in Section 2, Microwave Path Engineering Basics, of this manual to select the proper free-space attenuation value (in dB) based on the estimated length of the microwave path. Remember to subtract both antenna gains (local and remote) from the attenuator setting.10. Test the installed modules by performing the following: 11. Command a link loopback on the remote TRACER 6420 unit and run a test pattern from the connected T1 equipment. This will verify the data path across the RF link. Installing/Configuring T1 Hardware1. If possible, attach any or all of the intended T1 hardware to the TRACER 6420 units using the same workbench setup. This step offers the perfect opportunity to configure your T1 hardware for proper functioning with the TRACER 6420 hardware.2. To significantly reduce the probability of an unsuccessful field installation, resolve any remaining T1 equipment-to-TRACER 6420 configuration issues before field installation. See T1 Interface Alarm LEDs on page 105 for more information on resolving T1 interface alarm conditions.Installing/Configuring Ethernet Hardware1. If possible, attach any or all of the intended Ethernet hardware to the TRACER 6420 units using the same workbench setup. This step offers the perfect opportunity to configure your Ethernet hardware for proper functioning with the TRACER hardware.2. To significantly reduce the probability of an unsuccessful field installation, resolve any remaining Ethernet equipment-to-TRACER 6420 configuration issues before field installation.4xT1 Module Initiate a line loopback on the local TRACER 6420 unit and run a test pattern from the connected T1 equipment.
