Chapter 1. Introduction 1-13
CPN 62140 12/01/02
Lynx.GX and Tsunami Radio Installation and Configuration
Chapter 2. Planning for Installation
There are several planning factors to be considered prior to installing the Tsunami or Lynx radio system.
In addition to selecting the installation site, you must:
Calculate:
º Predicted Path Availability
º Anticipated RSL and Fade Margin
Determine:
º Frequency Plan
º Required Antenna Size and Type
º Required Transmission Line Types and Lengths
Plan for:
º The unit’s continuous power consumption needs
º Antenna installation
º Lightning protection and system grounding
º Radio hardware mounting
º Cable installation including egress
Also, before installing the system, you may want to perform 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 (such as antenna alignment and path dynamics) which can lead
to system turn-up delays during troubleshooting. By pre-testing the radios, you reduce the chance of their
being the cause of system turn-up problems, so you can focus on other factors, such as transmission line,
antenna alignment, path clearance, and other factors. See “Back-to-Back Testing” on page 58.
Selecting a Site
The radio site must have:
■ Access to appropriate power
■ Access to the telecommunications system you want to interconnect
■ Line-of-sight to the other radio location with adequate path clearance
■ Location for mounting the antenna
Line-of-Sight and Path Clearance Guidelines
The frequencies of these radio transmissions are not intended to pass through trees or other obstacles.
Factors to consider include earth curvature, future growth of trees, and height of buildings. In addition to the
line-of-sight requirement, a well-engineered path has additional path clearance to allow for signal loss due to
partial obstructions, atmospheric ducting, and ground reflections.
Chapter 2. Planning for Installation 2-14
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
To maximize link availability, calculate 0.6 times the first Fresnel zone and add this value to path clearance
based upon the primary path (in addition to earth curvature, trees, buildings, and so on).
The radios will not perform properly unless they have line-of-sight and proper path clearance between their
corresponding antennas.
Calculating Availability
Availability of the microwave path is a prediction of the percent of time that the link operates without
producing an excessive bit error rate (BER) due to multipath fading. In the absence of direct interference,
availability is affected by the following:
■ Path length
■ Fade margin
■ Frequency
■ Terrain (smooth, average, mountainous)
■ Climate (dry, temperate, humid)
Depending upon the type of information carried over the link and the overall network design redundancy, you
may want to design for a specific availability rate. For example, if the data or voice traffic carried by the
radio is critical, the link can be designed for a very high availability rate (for example, 99.999% or 5.3
minutes of predicted outage per year).
Availability can be improved by increasing the fade margin either by making the path shorter or by using
higher gain antennas in conjunction with lower loss transmission line (using a higher quality transmission
line, shortening the length, or both).
Calculating Received Signal Level and Link Budget
Use the following formula to estimate the received signal level (RSL):
RSL (dBm) = Pout - L1+ G1 + G2 - L2 - Lp
where:
Pout is the transmitter output power (in dBm)
L1 is the total loss of all transmission elements between the antenna and the RF Unit on
one side of the link (in dB)
G1 is the gain of the antenna on one side of the link (in dB)
G2 is the gain of the antenna on the opposite side of the link (in dB)
L2 is the total loss of all transmission elements between the antenna and the RF Unit on
the opposite side of the link (in dB)

Lp is the Path loss, defined by:
Lp (dB) = 96.6 + 20 log10F + 20 log10D
where:
F is the Frequency of the radio system in GHz (5.8 in the case of this model)
D is the Distance of the path in miles
The results of this link budget calculation are very important for determining any potential problems during
installation. If you have calculated the expected RSL, you can verify that it has been achieved during
installation and troubleshooting, if necessary.
In the USA and Canada, this model radio can be installed with any gain directional antennas, as there is no
Effective Isotropic Radiated Power (EIRP) limit for the application of these systems for fixed point-to-point
applications. In other countries, EIRP limits may apply.
In the case of EIRP limits, use the lesser of either (Pout - L1+ G1) or the EIRP limit within the previous
equation. You may have to check this equation in both directions to assure legal application.
An EIRP limit is the maximum RF energy allowed to be transmitted, as measured at the transmitting antenna,
and is usually determined by government regulations.
Calculating Fade Margin
The fade margin is the difference between the actual received signal and the radio's threshold. Using the
formula provided in the previous section, you can calculate the anticipated RSL. Compare this RSL to the
specified threshold of the Lynx radio, and calculate the fade margin as the difference between the two signal
levels.
Proxim Corporation recommends that you design your link to your desired availability standard, as discussed
in a following section. However, independent of the availability standard, the following guidelines are
recommended for minimum fade:
■ Greater than or equal to 15 dB for all paths, whenever possible, and always for path lengths greater than
2 miles.
■ No less than 10 dB for any path length (this is not recommended, but can provide adequate performance
if the path length is very short—less than 2 miles over non-reflective terrain and in non-refractive
atmospheric conditions).
Determining the Frequency Plan
When configuring radios in a hub or repeater configuration, perform careful engineering of the radio
frequency plans and antenna locations to minimize potential interference between the nearby radios.
Chapter 2. Planning for Installation 2-16
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
As a rule of thumb, do not place opposite frequency plan radios (such as A1 and A2) at the same site. In
most cases, you should use the same frequency plan (such as A1 and A1) or, in some cases, a different
frequency plan from the same side of the band (such as A1 and B1, when more than one channel plan is
available).
With careful engineering, you can easily place more than one radio of the same frequency channel plan at the
same site. When designing these configurations, antenna size, antenna polarization, and antenna location
are critical.
Using alternate channels (such as A1 and A2) is highly unlikely to be successful (and therefore not
recommended) due to the high level of transmitter-to-receiver isolation required from the antenna system.
Antenna polarization should always be oriented such that ‘adjacent’ links are oppositely polarized relative to
one another (that is, vertically and horizontally). This provides additional discrimination of the received
signals coming into the hub site. If you must place an odd number of links at the same location, ensure that
the largest angle is bounded by the two links of like polarization. Further interference analysis may be
required to ensure these adjacent links will provide adequate separation.
Though external interference conditions are rare when using these radios, when these conditions do occur,
you can often overcome them by exchanging the radios from end-to-end, thereby changing the receive
frequency to the opposite channel at each end. Changing polarization on the antenna system to the
orientation that provides the maximum rejection to the interference is also an extremely effective measure.
The channel plan is illustrated in the following figure.
Figure 2 Channel Plan for 5.8 GHz 16xT1
The radio must have access to a supply of appropriate power, either DC or AC (if the AC adapter option has
been ordered). The unit can be powered from a DC battery system, or from a solar or generator power
plant, usually with battery reserves. Typically, either a ± 24 or ± 48 volt supply is used.
For DC, be sure the cable is of sufficient gauge to carry the necessary current and is less than three (3)
meters (9.75 feet) in length. A minimum gauge of 14 is recommended.
Before you install the radio, plan for the unit’s continuous power consumption needs. You also should plan
for backup power for critical communication circuits. Backup power allows the radios and associated
equipment continuous operation when primary power is interrupted.

Planning for Antenna Installation
In general, the larger the antenna used with the radio, the better the link performs. Larger antennas have
narrower beamwidth and higher gain, which yield better link performance (higher fade margin, better
availability) and improve immunity to interference (due to the narrower beamwidths).
However, larger antennas are more costly to purchase and install than smaller antennas and, in some cases,
require special installation equipment and more robust mounting structures (due to increased weight and
wind loading). You should consider all of these factors when selecting an antenna.
Prior to installation, determine the specific antenna location and mounting. The transmission line should be
kept as short as possible, so when line-of-sight placement of antennas allow flexibility, it is always desirable
for the equipment to be located closer to the antenna.
This advanced planning also yields the transmission line requirements.
Note: In areas for which transmitted output power restrictions apply, the use of larger antennas benefit
narrow beamwidths and receive gain. However, you may need to reduce output power to meet
regulations.
Only directional antennas should be used with Lynx radios. These typically are flat-panel or solid
parabolic antennas. Proxim Corporation recommends a minimum 3 dB beamwidth of 10° for
directional systems.

Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
Reviewing the Installation Process
The following is an overview of the installation process to assist you in your planning activities.
1. Test radios back-to-back and configure
■ Use a minimum of 60 dB and no more than 80 dB attenuation and a short low-loss RF transmission line
to connect the two radios.
■ Apply power.
■ Verify the RF Link LED is not red.
■ Verify configuration settings (through the Web Interface) for proper configurations.
■ Connect to services if possible to verify network connection and configurations.
2. Mount antennas
■ Antenna height can be critical for path clearance and line of sight.
■ Ensure that antennas will not be blocked by people.
■ Antenna structure must be secure for wind load and whatever climbing may be necessary.
3. Run transmission line route and egress, including lightning arrestors
■ Use proper transmission line.
■ Proper termination is critical, especially at 5.8 GHz.
■ Be careful with the bend radius and never kink the transmission line.
■ Secure transmission line to structures; be careful not to crush.
■ A direct connection to the antenna feed is ideal (if required, you can use a flexible jumper at the
antenna, a properly specified 90-degree connector/adaptor, or both).
■ Weatherproof all outdoor connections when completed with installation.
■ RF Lightning arrester is best located at the building egress point when the RF Unit is placed indoors.
■ Three lightning arrestors are recommended when the RF Unit is placed outdoors; one at the RF input
(from the antenna), one at the junction between the RF Unit and the interconnect cable, and one at the
building egress point.
■ All lightning arrestors and transmission line must be properly grounded.
4. Connect radios to antennas and power, including grounding
■ Connect to RF transmission line from antenna directly or using flexible jumper, if necessary.
■ Do not use 90° adapters unless rated at operating frequency.
■ Connect RFU-to-IDU cable.
■ Test power voltages and pinouts before connecting power to IDU.
Chapter 2. Planning for Installation 2-20
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
5. Align antennas
■ Rough align antenna azimuth and elevation based upon path planning (using compass bearing or
milestone sighting, telescopic sight, binoculars, and so on).
■ Use a Digital Volt Meter (DVM) or headphones/earpiece/speaker to read the radio’s RSL voltage provided
on the RFU to peak antennas.
º If the RFU is mounted indoors, you may need to temporarily run separate wires from the RSL port to
antenna. Alternatively:
▪ The RSL value can be provided by a ‘verbal relay’ or by two-way radio (or similar
communications device) from the radio location to antenna alignment personnel.
▪ The RFU can be taken to the antenna location temporarily for the purposes of antenna
alignment. An additional short transmission line jumper may be required for this approach,
along with TNC-to-N adaptors at each end of the primary transmission line.
▪ Coaxial couplers can be placed temporarily at each end of the primary transmission line to allow
for the RSL voltage to be sent to the antenna location.
■ Make sure antenna polarization is the same at both ends.
º Adjust alignment of one antenna at a time, one plane (azimuth versus elevation) at a time.
º Adjust each end multiple times until predicted RSL is achieved.
6. Check RSL against predicted results, iterate, and troubleshoot
■ Is the RF Link LED red?
º If so, keep aligning.
º If not (or green), the radios are talking!
■ Does the measured RSL at both ends closely match the predicted value?
º If too strong, probably OK.
º If not strong enough, keep aligning.
º If still not strong enough, double-check the prediction and compare to the actual installation (verify
antenna gains, lengths/type of transmission line, path length, and so on).
º Are you sure you have line of sight?
º Did you test the radios in advance?
º You could have a bad cable, connector termination, or antenna
■ Do you need to adjust the output power down?
º Check path calculations and regulations.
º Re-verify RSL after power is adjusted.
Chapter 2. Planning for Installation 2-21
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
7. Troubleshooting
■ Most common problems are poor transmission line connector terminations.
º Best way to test is a return loss measurement (VSWR).
º Basic function can be tested using a continuity and short test with DVM.
º The transmission line can be evaluated with a spectrum analyzer connected to the radio through the
cable and comparing when spectrum analyzer is connected directly to the radio without the cable.
º Transmission line loss can be evaluated with a back-to-back RSL test.
º “Tap and wiggle” testing of all terminations while monitoring RSL and alarms can expose poor
terminations.
■ Could be a faulty antenna.
º Very hard to tell without swapping.
º VSWR test on antenna feed can identify antenna problems.
º “Tap” test can expose a faulty feed for moisture or connector problems.
■ Could be a faulty radio.
º Back-to-back RSL testing normally exposes a faulty radio.
■ Could be a path obstruction.
º Re-evaluate path clearance including Fresnel zone criteria.
8. Connect services and test connectivity
■ Perform a loopback test, a BER test, or both.
■ Connect T1 connections, NMS connections, and so on.
■ Test network connectivity.
■ Double-check line codes and LBOs for all T1 connections.
Helpful Hints
■ Telephones plugged into the Orderwire jack provide verbal communication across the link after the link is
synchronized (very helpful to coordinate alignment and testing).
■ Use the FAR END button to determine status and RSL of the far-end radio for troubleshooting.
■ Keep radios at maximum (factory) power for the alignment phase.

Mounting the Lynx and Tsunami Radio Units
The following sections provide installation procedures:
■ IDU Installation
■ Indoor RF Unit Installation
■ Outdoor RF Unit Installation
There are two primary ways to install the Lynx and Tsunami radio system.
■ The first is the case in which both units (the IDU and the RFU) are mounted indoors or in a suitable
enclosure, stacked on top of one another, in a rack or on a tabletop.
■ The second is the case in which the IDU is mounted indoors and the RFU is mounted outdoors, either
near the antenna or simply at a location somewhere between the enclosure/structure egress point and
the antenna.
Complete installation of all cables and the antenna system prior to connecting power; refer to “Antenna
Installation and Adjustment Guidelines” for important information.
Chapter 3. Installing the Unit 2-25
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
Installing the Indoor Unit
Rack mounting of the IDU is the ideal configuration. The Lynx and Tsunami radio alternatively can be placed
on a tabletop or a cabinet shelf. You should secure the radio system with a strap when not mounted directly
to a racking system.
For rack mounting, to avoid interference with the RF unit or antenna cables, you should mount the unit at the
highest space in a standard 19-inch rack. Empty rack-mounting spaces above and below the unit are
recommended, especially if the surrounding equipment dissipates a considerable amount of heat (over 40W).
If you plan to mount the RFU indoors, use the top two rack spaces for the radio system, mounting the IDU
and RFU directly adjacent; leave a minimum of one space above the total 2-unit space for the radio.
Set up the radio for mounting (using the rack mounting brackets enclosed with the screws in the shipping
container) with the front edge projecting from the front face of a standard 19-inch rack. Alternatively, you
can reverse the rack-mounting brackets to install the unit at a flush position.
The radio has internal fans that intake on the left side and exhaust on the right side of the chassis. When
rack mounting, leave a small gap between the outer edges of the radio and the inside edge of the rack.
To rack-mount the IDU:
1. Set the unit on a flat surface and, using a screwdriver, remove the front screws on each side of the unit.
You must remove these screws to prepare the unit for bracket attachment.
2. Attach a mounting bracket to each side of the unit using the long mounting screws that are provided in
the IDU accessory kit.
The following figures illustrate mounting bracket attachment for the IDU only (occupying one space in a
19-inch rack) and for the combined IDU and RFU (occupying two spaces in a 19-inch rack).
Chapter 3. Installing the Unit 2-26
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
3. Position the radio in the rack and align the holes in the mounting bracket with the holes in the rack.
If you are installing the IDU in a 23-inch rack, you must attach extenders to the rack mounting brackets,
as shown in the following figure:
Chapter 3. Installing the Unit 2-27
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
4. Insert two bolts and lock washers, appropriate for your 19-inch rack, into each of the mounting brackets
and tighten.
Important: When the RFU is rack mounted, it must be mounted directly above the IDU and facing
with the connectors forward in the same direction as the front panel of the IDU (as
shown).
The IDU fan exhaust is used to cool the RFU in a rack mount configuration. Also, if one
unit is projection mounted, both units should be projection mounted. In either
configuration, an empty rack mount space is required above and below the configuration.
Installing the RF Unit in an Outdoor Configuration
The outdoor RFU installation is a two-step procedure:
■ Install the mounting bracket and plate onto the pole. Use two band clamps (not included).
■ Mount and secure the RFU on the mounting plate.
To install the RFU, follow these steps:
1. Hold the mounting plate with the upper and lower V-cut tabs in contact with the pole.
Chapter 3. Installing the Unit 2-28
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
2. Wrap band clamp around pole/mast and through the vertical slots near the top of the mounting plate.
Repeat for lower slots.
3. Tighten both band clamps sufficiently to prevent the mounting plate from rotating on the pole/mast; you
are now ready to mount the RF unit onto the bracket assembly.
4. Orient the RFU for mounting onto the mounting plate so that the connectors are pointed down and the
heatsink fins are facing away from the bracket.
5. Insert carriage bolts into the upper holes. Place both thumbs over the hex nuts; place the RFU onto the
mounting plate by setting the square portion of the carriage bolts into the upper, rectangular slots on the
mounting plate. Loosely attach the self-locking hex nuts.
6. Insert carriage bolts into the lower holes. Loosely attach the self-locking hex nuts.
7. Tighten all hex nuts sufficiently to prevent the RF U from any movement. Ensure the heads of the
carriage bolts are firmly against the mounting plate prior to tightening the self-locking hex nuts.
8. Install the RF lightning arrestor that connects to the antenna cable to the RFU Type-N connector labeled
To Antenna and seal the connectors using weatherproofing material (butyl and electrical tape, butyl
tape or self-vulcanizing adhesive) listed in “Installation Requirements.”
9. Install the IF/DC-passing lightning arrestor that connects to the IDU cable to the RFU TNC connector
labeled To IDU and seal the connectors using weatherproofing material.

Installing and Adjusting the Antenna
The installation information discussed in this section is generic. For installation procedures specific to the
antenna you are installing, refer to the antenna manufacturer’s documentation.
Antenna Installation
WARNING (FCC requirement for implementation in the USA):
Antennas used for the transmitter must be fix-mounted on outdoor permanent structures with a
separation distance of at least 1.5 meters from all persons during normal operation. Antennas
must be professionally installed. Installers must be provided with antenna installation
instructions and transmitter operating conditions, including antenna co-location requirements of
CFR47 Part 1.1307(b)(3), for satisfying RF exposure compliance.
Antenna installation consists of permanently mounting the antenna to the mast, pole, or tower and then
attaching the RFU to it.
The antenna and RFU assembly must be mounted outdoors on a tower, building roof, or other location that
provides line-of-sight path clearance to the far-end location. In some cases, the antenna can be mounted
indoors, behind a window. However, RF attenuation through windows can vary greatly, depending upon the
glass and any coatings that might be present, plus the precise location and angle of the antenna relative to
the window. In cases of indoor installations, ensure that the antenna location is restricted and bear in mind
the RF exposure requirements of the warning statement above.
In general, antennas smaller than 2.0 feet diameter, or 1-foot panels, are not recommended for use with
these radios.
Antennas should be:
■ Ordered with the suitable mounting kit specific to the site requirements.
■ Very rigidly mounted, with adequate room for azimuth and elevation adjustment from the rear.
The antenna polarization must be the same at both ends of the link, either vertical or horizontal.
In general, antenna mountings require a support pipe to which upper and lower support brackets are
attached with U-bolts. The antenna and optional elevation and azimuth adjustment rods are then mounted
onto the support brackets. The entire structure must be adequately grounded for lightning protection. The
antenna system must always be installed according to the manufacturer's instructions.
Unless special test equipment is available, two operating Lynx radios are required to align the antennas.
Alternatively, you can use a CW generator to transmit a signal toward the end being aligned.
The antenna is coarse-aligned using visual sighting and then fine-aligned using the receive signal level (RSL)
voltage of the radio.
The RSL voltage reading still can be used to peak antennas even if the wireless units have not synchronized;
however, you cannot measure far-end RSL from the near-end terminal until the units are synchronized.
Chapter 3. Installing the Unit 2-30
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
Alignment Guidelines
When aligning antennas, if the RFU is located indoors or distant from the antenna location, you may want to
run wires or a cable from the RSL test point to the antenna so that the voltmeter reading or audio device is
directly visible and audible to the technicians aligning the antenna. Alternatively, you can use coaxial
couplers to couple the RSL voltage from an IDU to bring the voltage to the antenna location. If this approach
is used, remove couplers after alignment is complete. You may also temporarily mount the RFU near the
antenna for the purposes of alignment (an additional short RF transmission line may be required).
A cellular telephone or two-way radio can be useful for coordinating alignment activities between both ends
of the link. Once you have coarse-aligned and synchronized the units, you also can use the built-in order
wire phone service to coordinate installation.
An order wire telephone can provide end-to-end voice communications once the units are synchronized.
Synchronization usually can be accomplished by coarse alignment alone. After synchronization, you can use
the orderwire phones to communicate between radio sites for antenna fine alignment activities. The phone
interconnect cable can be extended to the antenna when desired.
The larger the antenna size, the more critical alignment becomes. For example, with a 2-foot dish at 5.8 GHz,
the antenna can be moved ±3 degrees off the correct heading before the receive signal level drops by 3 dB.
This compares with a 6-foot dish, which may only be moved ±1 degree for the same degradation.
■ It is critical that antenna alignment be performed on one end of the link at a time, one plane at a time.
■ One antenna should remain stationary at all times.
■ Each end should be fine-aligned several times, until the planned RSL is reached.
In some cases, you may need to perform coarse alignment using a wide arc in both azimuth and elevation
while reading the RSL to find the main beam of the opposite end antenna.
Note: The RSL voltage is slightly delayed, so make small incremental adjustments during the fine
alignment phase and wait for the RSL voltage to settle at each adjustment. When aligned to
maximum RSL, ensure that all antenna mechanics are tightened without impacting the alignment.
Coarse Alignment
To coarse-align the antenna, set the antenna for flat elevation (no up-tilt or down-tilt) using a spirit level;
point the antenna at a heading marker obtained using a compass/GPS (magnetic corrected) back-bearing
from an adjacent location (ideally, 100 feet or more away from the antenna). If the path has substantial
change to elevation from one end to the other, this may not be an advisable method for starting the
alignment activities. In such cases, compare antenna elevations at each end of the link and set the initial
elevation of the antenna to roughly match the anticipated up-tilt or down-tilt.
If you cannot set a heading marker sufficiently far away (for example when on a city building roof or looking
through a window), obtain a rough azimuth setting by sighting along the antenna feed or based upon
compass measurements made during the path planning stage.

Note: Use the instructions provided by the antenna manufacturer to verify that both antennas are on
the same polarization; otherwise, the RSL will be approximately 25 to 30 dB below the calculated
level.
Because maximizing the receive RF signal level at each end of the radio link is critical, most antennas also
require fine alignment using an operating link.
Once the coarse alignment is completed at both ends, the link can be powered and some level of reliable
communication established. The voltage at the Lynx test point can be measured with a DVM to determine
the relative receive RF signal level.
Note: Make sure that you read Power Connections prior to powering up the Lynx radios.
Fine Alignment
When fine-aligning the antenna:
■ Adjust the azimuth and then the elevation of the local antenna to maximize the RSL voltage.
■ Align the far-end antenna in the same manner, using the RSL voltage of its local RFU.
RSL Voltage Guidelines
The following example graph illustrates the typical variation of RSL voltage as the receive signal level is
increased from threshold to a higher level. There is some variation between receivers, but an approximate
estimate of the potential RSL value can be made using this figure.
12/
Figure 4 Typical RSL Voltage vs. Receive RSL
Note: Use the Factory Test Data Sheet shipped with your terminal to obtain the best estimate of your
RSL.
Chapter 3. Installing the Unit 2-32
CPN 62140 01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
Above -30 dBm RSL, the receiver can produce errors; however this level is rarely exceeded. Refer to
Calculating Received Signal Level and Link Budget to calculate the anticipated RSL.
During anomalous propagation conditions, the RSL can fade up but does not typically increase by more than
10 dB (except in unusual, very long paths, which may increase by 15 dB).
Antenna alignment should enable the RSL to peak to the level calculated in the link budget. If the RSL is
peaked but is approximately 20 dB below the calculated level, it is likely the antennas are aligned on a
sidelobe of the antenna's radiated signal. In such case, you must adjust the antennas in a wide arc in both
azimuth and elevation (at both sides) until the main lobe is located.
Other typical causes of low RSL are:
■ Path obstructions
■ Excess loss in connectors/cables (poor terminations, improper bend radius, kinked, crushed, and so on)
■ Poor quality or unaccounted for adapters and pigtail jumper cables
■ Different antenna polarization at each end of the link
■ Misadjustment of the radio’s transmit power output adjustment
■ Insufficient RF output power (faulty radio transmitter)
■ Faulty antenna
Establishing Connections
Antenna Connection
The Lynx radio is equipped with an N-type female connector at the antenna port. You can use a short length
jumper cable (such as 1/4-inch to 1/2-inch coax or pigtail of approximately 6 feet in length) fitted with two
N-type male connectors to connect the antenna port to the antenna (if the RFU is located near the antenna)
or to the primary transmission line (if the RFU is mounted remotely from the antenna).
A low-loss 50-ohm cable is recommended for the antenna transmission line between the RFU and the
antenna (such as Andrew LDF4-50 or Times LMR-600 1/2-inch coaxial cable, an Andrew LDF4.5-50 or Times
LMR-900 5/8-inch coaxial cable, or an EW-52 waveguide).
The return loss presented by the transmission line at the RFU interface should be as high as possible (20 dB
minimum recommended). The length of the antenna transmission line should be kept as short as possible to
minimize losses.
To minimize feeder losses, use an elliptical wave guide (typical loss is 1.25 dB/100 ft. at 5.8 GHz) for
implementations with longer transmission line lengths (such as >200 feet) or long paths (such as >20 miles).
Depending upon path length and transmission line feeder length, ½-inch or 5/8-inch coaxial cables are often
sufficient.
Chapter 3. Installing the Unit 2-33
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
Antenna Cabling Guidelines for 5.8 GHz Units
■ Coaxial cables of 7/8-inch or larger diameter can exhibit moding at 5.8 GHz and are never recommended.
Also, some small diameter cable types, such as RG-8, will have high loss or poor VSWR at these
frequencies. If small diameter cables are required, be certain to keep the lengths of these cables as short
as possible.
■ For wave guide transmission line at 5.8 GHz, EW-52 wave guide is recommended. EW-63 will also work,
but may exhibit more loss.
■ Do not use right angle N-type connectors with the Lynx radios operating at 5.8 GHz unless the connector
has been specifically rated and tested up to 5850 MHz. Unless specifically designed for these
frequencies, these connectors may present high loss at these frequencies.
■ Do not use a low quality jumper cables with the radios.
■ Always precisely follow manufacturer’s recommended procedures and tools for termination.
Transmission Line Connection
If the RFU is mounted near the antenna, the RF transmission line can be pre-terminated at both ends and
simply attached from the antenna feed to the RFU without any special consideration to securing the
transmission line to the antenna structure (as the length is likely to be very short).
In this configuration, Proxim recommends you place an RF lightning suppression device specified for use at
5.8 GHz (such as Polyphaser LSX) between the RF transmission line and the RFU’s RF port, as close as
possible to the RFU. Always properly ground any lightning suppression device.
When the RFU is mounted near the antenna, generally follow the following instructions for the cable that is
used to connect the RFU to the IDU. This cable is likely to be longer and will also egress the structure in
which the IDU is located. It may require more care for installation, including grounding and securing the
cable.
Lightning suppression is required at the interconnection cable junction as close as possible to the RFU, as well
as at the egress point. For this cable, the lightning suppressors must be designed to pass DC and support
the intermediate frequencies (approximately 800 MHz) and the digital signals carried by this cable.
Polyphaser carries an appropriate device for this application.
To prepare the transmission line feeder or the RFU-to-IDU cable:
1. Cut the cable to the approximate length (allowing some excess).
2. Install the appropriate connector on the antenna or RF Unit end:
Place tape or a covering over the connector end so that debris cannot harm the connector.
Pull the transmission line through the cable ducts, trays, or conduit (as required) to the antenna, while
being careful not to kink or damage the transmission line in any way.
Chapter 3. Installing the Unit 2-34
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
RF transmission line must never be bent, twisted, or deformed in any way.
Pay close attention to the transmission line specifications for bend radius when installing.
3. Support the transmission line in a tray on horizontal runs and by hangers on vertical runs. Space
hangers according to the manufacturer instructions (typically every five feet under conditions of no ice
and not greater than 85 mph winds).
4. Ground the transmission line using the manufacturer grounding kit. Grounding kits attach to the outer
copper conductor. Install grounds at the antenna, at the bottom of the antenna structure (if applicable),
and where the transmission line enters the building. Be sure to ground long transmission line runs
every 100 feet.
5. Install lightning protection devices, including proper grounding and termination to cables. There should
always be a lightning protection device at the egress point for whatever cables egress the building or
enclosure.
For an all-indoor implementation, the in-line lightning protection device must be rated for the operating
frequency of the Lynx (5.8 GHz).
Lightning protection for the RFU-to-IDU connection portion of an outdoor implementation of the RFU
must be rated to 800 MHz and must be non-blocking to DC. Proxim recommends placing lightning
arrestors near the RFU and at the egress point for 2-piece systems. Lightning arrestors must be
properly grounded to operate.
6. After installation, terminate the transmission line with an N-type male connector or adapter attached at
the equipment end. For wave guide, this typically requires a CPR-to-N adapter.
Be sure to use manufacturer-specified connectors and termination tools, and follow termination
instructions precisely. Improper transmission line terminations can cause excess losses and reflections
that can lead to many problems with the system.
7. Prior to operation, check the electrical integrity of the transmission line, including all connectors, with a
simple DC check between the center conductor and outer conductor (this is neither possible, nor required
for wave guide).
The transmission line ideally should be connected directly to the antenna at one end and to the Lynx
antenna port at the other end (through the RF Lightning arrestor). However, short pigtail jumper cables
may be required to avoid sharp bends in the primary transmission line to limit stress on either
connection.

Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
Power Connections
The following sections describe the wiring and power connections for the Lynx radios.
The Lynx radios do not have a power on/off switch. When you connect the DC power, the unit powers up
and is operational immediately. There can be up to 200mW of RF power present at the antenna port. The
antenna port should be terminated (either connected to an antenna or an appropriate 50-ohm load, such as
provided by a fixed RF attenuator) before power is applied. Connect the cable between the IDU and the RFU
prior to applying power. The IDU can be powered separately (with no cable or RFU present), but do not
connect the RFU without removing power first; then connect the cable and re-apply power.
Power is connected using the terminal block contained in the accessory kit. The terminal connector is a 3-pin
mating connector.
Use the pin information listed in following tables, along with the associated figures, to wire the terminal and
connect the DC power supply properly.
For DC power return connection, connect to the opposite voltage (either the -DC or the +DC Pin) and connect
the return to ground at the DC power plug on pin 2.
Necessary ONLY if power supply needs to be
referenced to chassis ground.

Note: Each Lynx terminal block must be fused externally with an 8 Amp maximum fuse. The DC power
cable must be shorter than 3 meters (9.75 feet).
Chapter 3. Installing the Unit 2-36
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
To wire the DC power, wire the power cable with an adequate current rating (minimum 18 AWG) into the
terminal block using the screw connections on the terminal block.
Figure 7 Power Connection for IDU
The recommended minimum current rating of external fuses and cables is 5 amps. The Lynx radios consume
less than 3.1 Amp + 48V.
■ If using negative power, connect the negative voltage to pin 1. Connect the ground return connection
to pin 3 and use an optional jumper to pin 2 for ground reference.
■ If using positive power, connect the positive voltage to pin 3. Connect the ground return connection to
pin 1 and use an optional jumper to pin 2 for ground reference.
The ground connection is available using pin 2. Do not ground both sides of the power supply.
Proxim recommends you leave the ground connection floating if the power supply also is floating. This
configuration can help avoid ground loops and provide the best lightning protection; however, if the power
source is referenced to ground, this configuration may not provide adequate grounding for lightning
protection. This configuration is more susceptible to lightning damage no matter what grounding scheme for
the radio power supply is chosen.
A grounding screw and nut is provided on the left front panel of the IDU. Be sure to use the local electrical
code to determine wire size and proper connection to the grounding screw.
Note: Proper grounding, either through the chassis or the power supply, is important for protecting the
unit against lightning. A grounding screw hole is provided on the front panel.
After wiring the terminal block for power connection, use a digital voltmeter (DVM) to verify voltage and
polarity of the plug.
Chapter 3. Installing the Unit 2-37
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
CAUTION!
Do not connect the DC power plug to the terminal until the RFU is connected to the IDU and
the antenna, or appropriate termination.
Do not connect the RFU-to-IDU cable while power is applied to the IDU. The IDU can be
powered without the RFU connected; however, power should be removed before the RFU is
connected and reapplied after the cable is connected and the RFU is properly terminated at
the RF port.
Adjusting Output Power
In certain cases, you may need to adjust the output power lower from the factory setting; for example, to:
■ Meet EIRP (Effective Isotropic Radiated Power) limits
■ Avoid exceeding the maximum far-end RSL of -30 dBm
■ Coordinate a hub or repeater location
Note: In certain countries, Effective Isotropic Radiated Power (EIRP) limits dictate the maximum output
power the Lynx radio can transmit, given transmission line loss and antenna gain. Consult with
appropriate government agencies or Proxim Corporation if there is any question regarding
maximum output power allowed. Never adjust power above the factory default settings.
Using the NMS port, you can adjust the output power from factory settings.
Note: For precise measurement of transmitter power, a calibrated RF power meter (such as the HP 435B
with Power Sensor HP8481) is recommended. This power sensor can be connected directly to the
output of the radio without exceeding the power rating. With some power meters, it may be
necessary to place a calibrated in-line fixed attenuator between the radio antenna port and the
power meter so as to not exceed the power meter's maximum input level. Thruline power meters
do not operate at Lynx RF frequencies.
If adjusting the output power to meet an EIRP limit, you must calculate the overall system gains and losses,
including feeder losses for the type of transmission line installed and the antenna gain.
You can determine the radio transmit power for EIRP limited installations using the following equation:
Tx Power (dBm) = EIRP Limit (dBm) + Transmission System Losses (dB) - Antenna Gain (dB)
Establishing a Connection Between the Units
Follow these steps to establish connection between the radios:
1. Ensure that the antennas at both ends are aligned.
Perform a general alignment of the antennas on both ends of the path using binoculars, compass, or
other related tools. You must have the antennas aligned as accurately as possible before putting radio
Chapter 3. Installing the Unit 2-38
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
traffic over the link. This helps in getting the system running more rapidly. Assure that both antennas
are set for the same polarization (vertical or horizontal at both ends).
2. Connect the transmission line to the antenna and feed it to the Lynx radio location.
Connect the opposite end of the transmission line to the N-type female connector located on the RFU
through a lightning arrestor. If the RFU is mounted indoors or in a shelter, the lightning protection
should be located at the cable egress point. If the RFU is mounted outdoors, it can be mounted at the
RF input port of the RFU. The transmission line connection must be terminated into an antenna or a load
before DC power is applied to the radio.
3. Connect RFU to IDU.
Connect the cable the runs from the RFU to the IDU. If the RFU is mounted outdoors, ensure that proper
lightning protection is used at the shelter or building egress point as well as at the RFU connector.
4. Confirm DC power connection.
With the DC power source active but not plugged into the Lynx radio, confirm with a voltmeter that the
DC mating connector has the proper power connections as discussed in Power Connections.
– Verify the polarity and the absolute voltage on all pins.
– Verify ground connection for power (if applicable).
– Ensure that the RF Antenna port connection is properly terminated before applying power.
5. Connect power to the Lynx radio.
When the unit is initially powered-on, some alarm conditions may be present. This is normal and alarms
can be ignored at this time.
6. Adjust RF power (if necessary).
Using the NMS port, verify the RF output power setting and, if necessary, adjust the output power of the
local transmitter in accordance with the path analysis calculations.
In cases of no EIRP limits, the radio transmitter output power should be left at the factory setting, except
for very short paths using very high gain antennas, where excessive power may not be advised (in which
case power should be reduced).
Terminate the RF output port at all times when power is applied to the Lynx radio. Therefore, disconnect
power to the unit before connecting a power meter; reapply power once connected.
Often, an RF power meter has a limit to the input power it can measure without damage. Proxim advises
you place a calibrated fixed value RF attenuator (typically 20 dB or more) between the Lynx radio and
the power meter to ensure proper operation and safety for the RF power meter. The value of this fixed
Chapter 3. Installing the Unit 2-39
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
attenuation then can be added to the value of the RF power meter reading to obtain the actual
transmitter output power.
7. Confirm Received Signal Level (RSL).
Connect a voltmeter to the RSL measurement port on the RF Unit. This voltage reading corresponds to
the Received Signal Level (RSL) of the near-end radio. RSL is the amount of signal the near-end radio is
receiving from the far-end radio. Because the antennas have not been finely aligned, the RSL value at
this time will not be very high. However, you can verify that some communication is taking place
between the two units.
Use the RSL voltage reading to align the antennas. Align one antenna at a time as discussed in
“Alignment Guidelines” on page 31. Align both ends of the link before proceeding.
The RSL voltage output on the unit’s front panel puts out a voltage over the usable range of the unit.
The RSL of both sides of the link can also be measured using the NMS port.
Several factors can contribute to low RSL:
º Incorrect antenna alignment (aligned on a sidelobe and not on the main signal)
º Improper polarization orientation of antennas (horizontal versus vertical)
º Transmission line problems (loose connections, bent or damaged cables, “loss-y” adapters, improper
termination)
º Path obstructions (trees, buildings, hills, and so on)
º Path clearance (line-of-sight, earth curvature, Fresnel zone, diffraction, and partial obstruction)
º Weather (inversion layers, ducting, and multipath)
º Antenna feed (coaxial/connector) problem
º Highly reflective surfaces of the path terrain
If RSL is lower than anticipated, re-check the path clearance and transmission line, as these are the
typical causes of low RSL.
You can verify radio operations by connecting units back-to-back with attenuators (60-80 dB), as
described in “Back-to-Back Testing” on page 58. If the problem persists, see “Troubleshooting” on page
49.
The transmitter output power adjustment on the radio affects the RSL. Depending upon EIRP limits (if
any), path distance, and antenna gain, you may need to adjust the output transmit power to the proper
level before putting the units in service.
Chapter 3. Installing the Unit 2-40
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
8. Verify the channel plans.
Verify that the units follow the same channel plan and that the opposite Tx and Rx frequencies complete
a matched pair of radios (for example, A1 and A2 make up a matched pair).
9. Connect the unit to the intended telecommunications equipment to pass the T1 traffic.
Connect to the T1 circuits using 8-pin modular (RJ-48C) connectors. All front panel LEDs should either
be off or green. If any LEDs are red, see “LED and Control Button Descriptions” on page 42 or
“Troubleshooting Alarms” on page 55.
Viewing the Radio Front Panel
This section describes the front panel components, LEDs, and control buttons for the Lynx.GX .
The IDU front panel can be thought of as having three distinct parts.
■ The left portion of the IDU contains the connection for the RF Unit, the DC power connection, and the
RSL and GND test points.
■ The middle portion of the IDU contains connectors specific to the Lynx 16T model.
■ The right portion contains LEDs, CONFIG, ALARMS, and ORDERWIRE connections, and a FAR END toggle
switch.
Figure 8 illustrates the left and right portions of the IDU, which are the same for all Lynx.GX models. The
front panel components shown in this figure are described following the figure.

To RFU
This is an RF TNC female connector that is an integral part of the system. The TNC connector is used to
connect the IDU to the RF Unit.
The voltage on this connector is 42 VDC.
± 24 VDC OR ±48 VDC
The power receptacle recommendation for positive or negative DC power is 24 or 48. However, it will
accept any voltage between 20 and 63 Volts. Optionally, you can use an AC power adapter. For
additional information, see “Power Connections” on page 36.
RSL / GND
There are two front panel test points. Connecting a voltmeter across the GND and RSL front panel test
points, the voltage reading corresponds to the Received Signal Level (RSL) of the near-end radio. For
example, a value of .65V corresponds to –65 dB. Pressing and holding the FAR END button while
measuring the voltage at these test points displays the RSL of the far-end radio.
CONFIG
This is a serial interface port (RS-232) to the radio using a Female DB-9 connector. This port provides
connection to a computer or terminal using a standard null-modem cable for retrieving diagnostic
information, and allows IP and SNMP Community String configuration for the radio. The settings for this
port are 9600 bps, 8 data bits, No Parity, 1 Stop Bit, and No Flow Control. The terminal emulation is
VT100. See “Appendix B. Connectors and Pin Assignments” on page 63 for ALARM port connector
information.
ALARMS
This connector provides alarms for external alarm collection systems using a Male DB-9 connector. There
are two Form C relays that can be connected to other transmission equipment for monitoring alarm status
locally or remotely. One alarm represents Major alarms (usually alarm conditions) and the other Minor
alarms (usually warning conditions). See “Appendix B. Connectors and Pin Assignments” on page 63 for
ALARM port connector information.
NMS1 and NMS2
There are two Ethernet 10/100 Base-TX connections for access to the Network Management System
(NMS) using SNMP, HTTP, or Telnet. Both of these connections auto-negotiate speed and duplex, and
auto-sense MDI or MDI-X connections.
AUX DATA
This is a serial interface port (RS-232) using an RJ-45 connector, which supports speeds from 2400 to
19200 baud (set through the NMS). This allows auxiliary serial data connection from one end of the

wireless link to the other. It can be used for separate data connections for serial devices. See “Appendix
B. Connectors and Pin Assignments” on page 63 for AUX DATA port connector information.
VF
This RJ-45 connector is used to link two Lynx radios at a repeater site for Orderwire operation. This allows
Orderwire calls to and from any point in the network. The circuit is a 4-wire audio (2xTX and 2xRX) that
also can be connected to other existing Orderwire networks. All phones off hook hear and participate in
the call. See “Appendix B. Connectors and Pin Assignments” on page 63 for VF port connector
information.

Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
ORDERWIRE HANDSET
This connection is used to access the electronic orderwire function (a facility for telephone style service
from one radio to another). A standard analog telephone (with an electronic ringer) plugs into this
connector. You can dial the orderwire address of the far-end radio (or any radio in the network) to cause
that radio and any connected orderwire phone to ring; however, communications is automatically
established when both handsets are lifted off hook. This communication does not interrupt or interfere
with the other radio communications. The radio link must be operational to use this facility. The orderwire
feature can be very useful for installation, maintenance, and troubleshooting.
Note: All Lynx radios connected to the same orderwire network should have unique address settings
(telephone numbers).
Establishing Near-End to Far-End Communications using Orderwire
To establish near-end to far-end communications using orderwire:
1. Connect the telephone to the near-end and far-end radios.
Using a standard RJ-11 telephone cable, connect a standard electronic telephone (a touch tone phone,
complete with dialer) to the Orderwire connector on the radio front panel. This connector is wired
identically to a standard two-wire telephone jack. For connector pin assignment, see “Appendix B.
Connectors and Pin Assignments” on page 63.
2. Call the far-end radio.
With a telephone connected to each radio on opposite ends of the link, either telephone can be used to
dial-up the far-end location. The far-end radio internal ringer and the connected telephone ring, and if
answered, two-way full-duplex voice communication is established.
If the radios are connected in a repeater configuration, you can establish Orderwire services in the network
by connecting the radios (by cabling their front-panel VF connectors).
Orderwire operates on radios at each end of the repeater and at the repeater site. You can extend this
function through several repeater sites. For hub connections of three or more Lynx radios, an external 4-wire
radio is required to connect all devices for Orderwire operations.
Dialing an * [asterisk/star key] on the orderwire telephone implements an “all call” feature that rings all
connected radios. All telephones provide communication to all other telephones in the connected network.
Even if a particular telephone does not ring, it can still be used to talk and listen to any ongoing orderwire
activity if the orderwire is in use at other terminal locations.
Also, if a phone anywhere in the connected network has accidentally been left off-hook, the # [pound] key
can be used to mute all off-hook handsets until they are placed on and off hook again.

Port/Circuit Connections by Model
The following connection types are illustrated in the figures that follow.
10/100 BaseT / 100 BaseFX
The Tsunami Bridges use 100 Base-TX and 100 Base-FX RJ-48 modular port connectors and ST
connectors for the Fast Ethernet interface. They carry the signals in and out of the radio.
CHn
T1 or E1 data channels.
T1
A wayside data channel for T1 (DSX-1) interface voice connection. This channel does not affect the
Ethernet traffic.
E1
A balanced (120 ohm) wayside data channel for CEPT-1 interface connections.
Note: If an unbalanced 75 ohm connection (RJ-45 connector) is required, an optional 75ohm to 125
ohm balun will provide this interface. If you cannot locate these devices, contact Customer
Support.
DS-3
The connection for the DS-3 signal is BNC female (75 Ohm, unbalanced).
DS-3 input: 75 ohms unbalanced connection, shield floating with respect to chassis ground (user may
ground this shield if necessary).
DS-3 output: 75 ohms, configured by default as single-ended, with shield connected to chassis ground.
Note: DS-3 output can be changed to a 75 ohm output with shield floating with respect to chassis
ground by repositioning an internal jumper. This alternate configuration is recommended if the
shield is already grounded at the receiving end of the cable. Contact customer service for more
information.
10/100 Base-T and 100 Base-FX Ethernet Connections
The radios use 10/100 Base-T and 100 Base-FX RJ-48 modular port connectors and ST connectors for the
Fast Ethernet interface. They carry the signals in and out of the radio.

Maintaining the Radio
The radio does not require any regular maintenance. However, it is prudent to monitor the radio link at
regular intervals to ensure that the link conditions are not changing. When visiting a radio site for
maintenance, you should check the following items and record the results:
■ RSL voltage
■ Power voltage
■ Far-end RSL voltage
■ Alarm conditions
Also, be sure to verify that the unit has adequate ventilation and that the security ID is set similarly at each
unit through the network management system.
If any alarm conditions exist, you should record them. See “Troubleshooting Alarms” on page 55.
Data Stream Errors
When the radio is in service, errors in the data stream may occur. This is usually known to the operator
either by faulty data indications of downstream equipment or by external bit error rate testing.
It is possible that no alarms appear on the front panel during normal operations, even when there are errors
present in the data stream.
Some errors do not result in an alarm (such as bipolar violations, slow “dribbling” errors, improperly
terminated connections or incorrect settings), but are exhibited on downstream data processing equipment or
during a BER test.
In other cases, there may be data errors due to atmospheric conditions (fading), interference, or other
reasons, but not at a high enough error level to be indicated with the BER alarm LED. In the case of these
types of errors, the following information can be helpful to troubleshoot the radio link.

Indications
■ During external BER test, test equipment indicates errors
■ Downstream equipment (mux, channel bank, codec, router, and so on) indicates errors
Possible Causes
■ Path fading due to atmospheric conditions
■ Poor transmission line connections
■ Antenna problems, misalignment or path clearance
■ Received signal level (RSL) is too strong
■ Far-end radio transmitter circuitry is faulty
■ Near-end radio receiver circuitry is faulty
■ Interference
Recommended Actions
■ Verify 100 Base-T wiring
■ Follow the troubleshooting instructions described in “Radio Fail Alarms.”
Changing Frequency Plans
The information in this section can be used for indoor unit models only.
The Lynx.GX frequency selections are listed in “Frequency Plan Determination.” The near-end radio and the
far-end radio must be corresponding (for example, A1 / A2).
The frequency of a given Lynx terminal is set by:
■ The specific filter
■ The physical orientation of this assembly
■ A setting within the CONFIG port (see “CONFIG Port Command Line Interface”).
With respect to a given filter, the frequencies are fixed, because tuned RF filters are required for normal
operation. Changing of the (pre-tuned) radio frequencies may be required when installing spares or for
special situations (such as interference mitigation). This is accomplished by installing an alternate filter.
1. Remove any cables connected to the antenna connector on the diplexer (filter) and then remove the two
screws that mount the filter to the Lynx chassis.
2. Slowly remove the filter from the chassis being careful to not endanger the cables that are connected to
the rear side of the filter.
3. Disconnect the two SMA connectors that are attached to the rear of the filter with a 5/16-inch open end
wrench.
4. Select the new filter such that the frequency channel label on the filter corresponds to the desired
frequency channel (or rotate filter if applicable).
Appendix A Troubleshooting 2-50
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
5. Connect the two SMA connectors to the new or reoriented filter with the 5/16-inch open end wrench.
6. Slowly place the wired filter assembly so that it is flush with the rear panel.
7. Install the two screws that mount the filter to the rear panel.
8. Modify the operating frequency as described in the CONFIG menus.
9. Single-band versions of this radio can be interchanged from A1 to A2 by changing (but not rotating) the
installed filter. After the filter is changed, you must change the frequency settings within the
configuration menu (NMS) to match the installed filter.
Dual-band versions of this radio can also change channels, but the orientation of low-side or high-side
transmit must be retained. That is, an A1 radio can only be changed into a B1 radio with a new filter, but
not into an A2 or a B2. Likewise, the A2 radio can only be changed into a B2 radio with a new filter, but not
into an A1 or B1. The diplexer filters can go on any radio and must be properly oriented. After the filter is
changed, you must change the frequency setting within the configuration menu (NMS) to match the installed
filter.
Servicing Channel Orientations
For dual-band units, a spare of each band may be required. For single-band units, one spare Lynx terminal
can service both channel orientations. See “Changing Frequency Plans” for how to change frequencies of a
spare radio.
Customers with several radios, or radios in critical operations, are encouraged to purchase one or more spare
radios of each model in their system. This allows for rapid restoration of radio service in the unlikely event of
a radio failure.
Counteracting and Evaluating Interference
The recommended interference countermeasures available are:
■ Short paths
■ Narrow beam antennas (high gain)
■ Frequency selection
■ Antenna Polarization
■ Transmit Power
■ Equipment/Antenna Location
■ Use of a Spectrum Analyzer to evaluate potential interference
Short Paths
The single most effective countermeasure against interference is to maintain “short path” length. This may be
achieved by dividing long paths into multiple small paths by cascading hops. Intermediate repeaters can be
formed using back-to-back Lynx terminals and transmit output power reduced, if required.
Appendix A Troubleshooting 2-51
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
By definition, “short path” is defined as 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 at 5.3/5.8 GHz.
Narrow Beam Antennas (High Gain)
This is the next most effective countermeasure. Narrow-beam antennas ensure that the transmitted power is
sent in a single direction; this minimizes the possibility of causing interference inadvertently to other users.
Narrow beam antennas also reject off-azimuth signals being received from potential sources of interference
and have high gain, which boosts desired receive levels and improves the carrier-to-interference ratio.
When selecting narrow beam antennas, it is helpful to know that larger antennas generally out-perform
smaller antennas. Another important antenna specification is the front-to-back ratio, which ensures rejection
of unwanted signals from azimuth angles behind the antenna.
Frequency Selection
The Lynx radios offer several distinct non-overlapping frequency channel plans (see “Determining the
Frequency Plan” on page 16 and “Changing Frequency Plans” on page 50) and the unit’s RF filter can reject
interference more than 10 MHz away from the receive frequency.
Offset frequencies combined with other countermeasures may enable several receive channels to operate at
a single hub site. Because of the limited spreading ratio used, frequency selection is more efficient than code
selection for interference rejection when operating multiple Lynx terminals at a single site.
You often can overcome interference by exchanging frequencies of both ends of the radio link (for example,
change your A1 terminal to an A2 and change the other end from an A2 to an A1). Also, changing channel
plans (for example, from A to B) can be very effective.
Note: The information in this section can be used for indoor unit models only.
The Lynx frequency selections are listed in “Determining the Frequency Plan” on page 16. The near-end
radio and the far-end radio must be corresponding (such as A1 / A2).
The frequency of a given Lynx terminal is set by the specific filter, the physical orientation of this assembly,
and a setting within the CONFIG port.
With respect to a given filter, the frequencies are fixed, because tuned RF filters are required for normal
operation. Changing of the (pre-tuned) radio frequencies may be required when installing spares or for

not into an A1 or B1. The diplexer filters can go on any radio and must be properly oriented. After filter
is changed, the frequency setting within the configuration menu (NMS) must be changed to match the
installed filter.
Servicing Channel Orientations
For dual-band units, a spare of each band may be required. For single-band units, one spare Lynx terminal
services both channel orientations.
Customers with several units, or units in critical operations, are encouraged to purchase one or more spare
radios of each model in their system. This allows for rapid restoration of radio service in the unlikely event of
a radio failure.
Antenna Polarization
Cross-polarized antennas can provide approximately 20 to 30 dB discrimination of unwanted signals. The
actual discrimination depends upon the antenna design and any rotation of polarization along the path (for
example, due to reflections). Discrimination only exists between two orthogonal polarizations:
■ Vertical versus horizontal
■ Left-hand circular versus right-hand circular
There is only 3 dB discrimination between circular and linear (vertical or horizontal) polarization.
Interference can sometimes be overcome by changing antenna polarization at both ends of the link.
Appendix A Troubleshooting 2-53
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
Transmit Power
The maximum level into the receiver is -30 dBm. Errors can occur in the receive data stream above this
level. You should reduce transmit output power on very short paths to avoid overload.
Equipment/Antenna Location
Interference is occasionally caused by the unit or the antenna being too close to another similar transmitter.
Moving the unit, the antennas, 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. Before turning up a new hop, use a spectrum analyzer to monitor the spectrum at each end to
check for possible interfering signals. For more details, see the section that follows.
Use of a Spectrum Analyzer to Evaluate Potential Interference
Connecting to the antenna and using “peak hold” on a spectrum analyzer, the spectrum across the receive
frequency range of the radio can be swept and any signals being received at levels above the radio's specified
threshold identified.
If potential interfering signals are found, you can change the Lynx frequency plan to avoid a receive channel
that may contain significant interference (see “Changing Frequency Plans” on page 50). For example,
interference can be reduced by moving from the A1/A2 plan to the B1/B2 plan, or by swapping terminals or
RF filters so that A1 becomes A2. Signals outside the receiver frequency range can be ignored: they do not
cause interference.
If a spectrum analyzer is not available, you can use the RSL voltage to indicate the background noise and
interference level within the receiver RF filter band when the far-end transmitter is turned off. With the far-
end radio turned off, if an RSL voltage level above the radio's threshold level is measured, there is potential
interference in this frequency channel.
When using a spectrum analyzer for determining the presence of interference, use very narrow resolution
bandwidth settings to detect signals down to the unit’s threshold (approximately -80 dBm, depending upon
the type of radio).

Troubleshooting Alarms
Use these troubleshooting guidelines when you receive:
■ RF Link Alarms
■ Radio Fail Alarms
■ Far End Alarms
RF Link Alarm
This LED indicates that the demodulator function is not synchronizing with the intended received signal.
Possible Causes
■ Severe path fading due to atmospheric conditions, usually accompanied by low RSL voltage reading
■ Poor transmission line connections, usually accompanied by low RSL voltage reading
■ Antenna problems, misalignment, or path clearance, usually accompanied by low RSL voltage reading
■ Improper radio settings (such as frequency channel)
■ Received signal level (RSL) is too strong
■ Interference
■ Far-end radio transmitter circuitry is faulty
■ Near-end radio receiver circuitry is faulty
■ Link security ID not the same for each radio
Recommended Actions
Check the following at each end of the link:
■ Verify that rear panel filters are opposite channel plans on each end (for example, one is A1 and other is
A2).
■ Verify that radio frequency settings match each installed filter using the NMS Config menu.
■ Verify that all connections between radios and antennas are secure and all devices between radios and
antennas are rated for the radio frequency band (5.3/5.8 GHz).
Measure RSL by placing a voltmeter across RSL and GND test points and:
1. Comparing this voltage to the Factory Test Data Sheet and estimating the RSL in dBm.
2. Comparing this to the RSL that was expected using path calculations (see “Calculating RSL and Link
Budget” on page 15).
3. Pressing and holding the DISPLAY FAR END button and measuring the far-end RSL (while continuing to
hold the button) or on those models without FAR-END RSL on the front panel, using the built-in browser
software to acquire the near-end and far-end RSLs.
Appendix A Troubleshooting 2-55
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
4. Comparing these RSLs to the Factory Test Data Sheet for the far-end radio and estimating the RSL in
dBm.
5. Comparing this RSL to the expected RSL from the link budget calculations.
Excessive Loss
If RSL from both ends of the radio are approximately the same as each other, but lower than anticipated for
this installation, then the likely cause of the BER alarm is excessive losses between the radios. Excessive loss
problems could include the transmission line at either end, all adapters, connectors, the antennas, the
antenna alignment, as well as the path itself (any obstructions or clearance problems).
Verify antenna alignment, line-of-sight, and path clearance; if this does not improve RSL, check all devices
between the radios and their antennas at both ends. Make sure all transmission lines, connectors, and any
other devices are properly rated for operation at the radio's frequency (5.3/5.8 GHz).
Power Adjustment
If only one end has low RSL, this could be caused by low transmit output power from the opposite end radio.
Verify that the transmitter output power of the radio opposite to the low RSL receiver has been set in
accordance to path calculations or EIRP restrictions (where applicable).
Power adjustment must be performed by professional installation personnel only. The PWR test
point can be used and compared with the Factory Test Data Sheet; the front panel recessed potentiometer
can be turned clockwise to increase power. If an RF power meter is available, you can connect it to the RF
output of the radio for precision measurement. This test also verifies that the radio transmitter is working
properly.
If one terminal (or both) has high RSL, this could be caused by a very short path or interference.
Short Path or Interference
To verify the possible presence of interference, remove DC power to the unit opposite the one that is reading
high RSL. Once power is removed, measure RSL on the remaining radio. If RSL voltage is lower than that
listed for “Threshold” in the Factory Test Data Sheet, an interfering signal is present.
If interference is suspected, the easiest potential remedy is to swap frequency channels on both sides of the
link. (see “Changing Frequency Plans” on page 50). Swap terminals at both ends of the link so they are the
opposite of their original installation. After both ends are moved, reconnect the radios and determine
whether the BER alarm is still active. If so, you can install other frequency channels or try other interference
counter-measures, as discussed in “Counteracting and Evaluating Interference” on page 51.
Appendix A Troubleshooting 2-56
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
Possible Radio Failure
If all path related and data input problems have been pursued and the BER alarm is still active, the problem
could be related to a radio failure. Although radio failure typically is indicated by more severe alarm
conditions, it is possible that one of the radios may be out of specification, and this could be the cause of the
BER alarm. A back-to-back test verifies proper radio operation. See “Back-to-Back Testing” on page 58 for
more information. A threshold test on both radios, along with a test to verify proper RF output power, would
be beneficial.
Perform a back-to-back test before returning any radio terminal to the factory for repair. A back-to-back test
verifies radio operation.
If the radios pass their back-to-back testing successfully, the problem is likely with the path, with the
connections between the radio and the antenna, or interference. Before you reinstall the radios, be sure to
set the output power to the appropriate level for the installation.
Radio Fail Alarms
This LED indicates a known problem with the radio hardware.
Possible Causes
■ Internal synthesizers are unlocked
■ Internal digital circuits have failed
Recommended Actions
1. Remove power from the unit.
2. Verify that the correct frequency is configured on the browser Configuration tab.
3. Check to make sure power supply voltages are within specification.
4. Reapply power to the unit, even if the voltages were within specification.
If the RADIO FAIL alarm clears, place the radio back into service.
If the RADIO FAIL alarm does not clear, perform a back-to-back test to verify radio operation.
If the RADIO FAIL alarm is still active in a back-to-back test, return the radio to the factory for repair.
Far End Alarms
This LED indicates that there is an alarm condition present on the far-end radio. When the DISPLAY FAR END
button is pressed (and held), the status LEDs indicate the alarm conditions of the far-end radio.
Possible Causes
One or more alarm condition(s) exist on the far-end radio.
Appendix A Troubleshooting 2-57
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
Recommended Actions
Press and hold the DISPLAY FAR END button and observe the LED status.
Follow the troubleshooting instructions provided in “RF Link Alarms” and “Radio Fail Alarms.”
Measuring Radio Function
You can measure radio function using Back-to-Back Testing and Link Testing, which are described in this
section.
Back-to-Back Testing
Back-to-back testing is an ideal method of testing the Lynx radio. This testing eliminates link problems
caused by auxiliary equipment, installation, or the radio path, and isolates potential radio hardware
problems.
Note: Back-to-back testing must be performed to verify a radio problem before returning any radio to
the factory for repair.
Required Equipment for Test
Back-to-back testing must be performed with both radios at the same location. The following test equipment
is required:
■ DC power source capable of supplying approximately 90 Watts (total) to the radios (or two AC adapters)
■ One low-loss coaxial cable, N-to-N male
■ One (or more) coaxial in-line calibrated fixed attenuators, 40 to 80 dB total attenuation
The following test equipment may also be useful for further testing of the radio:
■ BER tester
■ Variable (60 dB range or more) RF attenuator (rated for the proper frequency, 2.4 or 5.8 GHz)
■ RF power meter
When the equipment is connected as shown in the following figure, both radios should have no alarm
conditions. If these conditions have been met, it is likely that the radio is operating in accordance to
specifications. If errors or alarms occur during this test, verify alarm status. If alarms or errors are still
present, the radio is likely to be faulty.
Figure 16 Back-to-Back Test Configuration
Appendix A Troubleshooting 2-58
CPN 62140 12/01/02
Lynx.GX and Tsunami Wireless Radio Installation and Maintenance
If further troubleshooting is required, you can insert a variable RF attenuator between the radios to fade
down the path to determine that the threshold specification is being met. You can run the threshold tests in
both directions to isolate the radio problem (if any). See “Link Testing” below for more information. You
can use an RF power meter to individually test each radio’s output power.
The Lynx radios will be damaged if appropriate attenuation is not supplied between
radios. You must provide a minimum of 40 dB and no more than 80 dB attenuation
between the two radios.
Link Testing
Link testing is the preferred way to evaluate a radio link's performance. It can be performed from end-to-
end or in link test mode (which tests both directions of the radio path). The following figure illustrates a
typical test configuration (which may include the radio’s path instead of in-line attenuators).
Figure 17 Link Testing Configuration
When performing testing, make sure of the following:
■ Disconnect all 100 Base-T inputs and outputs to both radios
■ Verify all configuration settings
You can perform link testing on the bench with two terminals back-to-back, or over the radio path. Also, it
can be performed from end-to-end (which requires two 100BaseT test sets over a link, the far-end unit
slaved to the near-end unit's clock) or in loopback mode.
Note: If link testing indicates an unacceptable level of errors, follow the instructions in “RF Link Alarms”
or perform a back-to-back test as described in “Back-to-Back Testing” on page 58.

Problem
■ Non-functioning CONFIG port
■ No access to the main menu
Solution
To verify your PC settings and RS-232 cable, bring up a HyperTerminal session with one end of the cable
plugged into the PC com port and the other end unplugged.
Using a piece of wire, short pins 2 and 3 together on the unplugged end of the cable. Make sure the
HyperTerminal window is active and enter some characters from the keyboard. You should see the
characters displayed in the HyperTerminal window. If you cannot see the characters, make sure the com
port settings are correct and try a different cable.
Double-check the HyperTerminal configuration settings and plug the cable back into the radio config port.
If the characters displayed as previously described, the HyperTerminal configurations are correct, and the
menu still is not displayed when you press the Enter key twice, the config port may already be “logged in.”
Once you are logged in to the Config menu, the config port stays logged in for the timeout period specified
under Main Menu item 4, User Configuration. The default is 7200 seconds or 2 hours.
If you unplug the cable or shut down HyperTerminal while you are still logged in and you restart the
HyperTerminal session, it appears as if you have a blank screen that is not responding.
To get started again, press the <Tab> key a few times. If you were in a screen with multiple entry fields
when you shut down, you will see the cursor move between those fields. Bring the cursor back to the
command field on the lower right part of the screen and press the <H> key followed by Enter to go back to
the Main Menu.
To log out of the config port, go to the command field and press the <H> key; then press Enter to go to
the Main Menu. Then press <O> and Enter to go to the Logon menu.
From the command field in the logon screen, press <D> and Enter to end the session. Pressing Enter twice
restarts the session and brings up the logon screen.

Repair Policy
The Lynx terminal includes comprehensive alarm indicators designed to diagnose potential faults. Should a
fault occur, it often can be resolved by operator adjustment.
Should a fault occur that cannot be resolved by operator adjustment and has been confirmed by back-to-
back testing, the equipment should be returned to the factory for repair.
The Lynx radios are complex systems not designed for user repair. Do not remove the cover or open any
part of the terminal. The complete terminal should be sent back in its original packing material for factory
repair.
Contact the factory in advance of returning the product. You will be assigned a Return Material Authorization
(RMA) number that authorizes your return. Units sent to the factory without an RMA number may delay the
repair process.
Be sure to include the following information:
■ RMA number
■ Description of the problem
■ Your name and telephone number
■ Return shipping address
■ Urgency of repair

AC
Alternating Current
Alternating current
In electricity, alternating current (AC) occurs
when charge carriers in a conductor or
semiconductor periodically reverse their
direction of movement.
amp
Ampere. An ampere is a unit of measure of the
rate of electron flow or current in an electrical
conductor. One ampere of current represents
one coulomb of electrical charge (6.24 x 1018
charge carriers) moving past a specific point in
one second.
amplifier
An electronic device that increases the voltage,
current, or power of a signal.
analog
An analog signal is one in which a base carrier’s
alternating current frequency is modified in
some way, such as by amplifying the strength
of the signal or varying the frequency, in order
to add information to the signal.
antenna
A device used for radiating or receiving
electromagnetic energy.
attenuate
To lessen the strength of.
AUX
Auxiliary
azimuth
Azimuth and elevation are angles used to define
the apparent position of an object in the sky,
relative to a specific observation point. The
observer is usually (but not necessarily) located
on the earth's surface. The azimuth (az) angle
is the compass bearing, relative to true
(geographic) north, of a point on the horizon
directly beneath an observed object. As seen
from above the observer, compass bearings are
measured clockwise in degrees from north.
Azimuth angles can thus range from 0 degrees
(north) through 90 (east), 180 (south), 270
(west), and up to 360 (north again).
The elevation (el) angle, also called the
altitude, of an observed object is determined by
first finding the compass bearing on the horizon
relative to true north, and then measuring the
angle between that point and the object, from
the reference frame of the observer. Elevation
angles for objects above the horizon range from
0 (on the horizon) up to 90 degrees (at the
zenith).
back-to-back testing
A simple way to verify that the radios are fully
operational before they are installed.
bandwidth
The width of a band of electromagnetic
frequencies. Used to mean (1) how fast data
flows on a given transmission path, and (2),
somewhat more technically, the width of the
range of frequencies that an electronic signal
occupies on a given transmission medium. Any
digital or analog signal has a bandwidth.
baseband
Any frequency band on which information is
superimposed, whether or not the band is
multiplexed and information is sent on sub-
bands. The frequency band is not shifted to
some other frequency band but remains at its
original place in the electromagnetic spectrum.
baud
Baud was the prevalent measure for data
transmission speed until replaced by a more
accurate term, bps (bits per second).
beamwidth, half power
In a plane containing the direction of the
maximum lobe of the antenna pattern, the
angle between the two directions in which the
radiated power is one-half the maximum value
of the lobe.
BER
Bit Error Rate. The bit error rate (BER) is the
percentage of bits that have errors relative to
the total number of bits received in a
transmission, usually expressed as ten to a
negative power.
BNC connector
Developed in the late 1940’s as a miniature
version of the Type C connector, BNC stands for
Bayonet Neill Concelman and is named after
Amphenol engineer Carl Concelman. The BNC
product line is a miniature quick
connect/disconnect RF connector.

diplexer
Combines signals so only one coaxial wire
needs to be run.
broadband
In general, broadband refers to
telecommunication in which a wide band of
frequencies is available to transmit information.
Because a wide band of frequencies is available,
information can be multiplexed and sent on
many different frequencies or channels within
the band concurrently, allowing more
information to be transmitted in a given amount
of time (much as more lanes on a highway
allow more cars to travel on it at the same
time).

Coaxial cable. A cable comprised of a center
conductor, surrounded by an insulating core,
with a braided or solid shield. Conductive shield
surrounds the core with outside insulation. duplex
Duplex communication means that both ends of
the communication can send and receive
signals at the same time. Full duplex
communication is the same thing. Half duplex
is also bidirectional communication, but signals
can only flow in one direction at a time.
codec
The term codec is also an acronym that stands
for "compression/decompression." A codec is
an algorithm or specialized computer program
that reduces the number of bytes consumed by
large files and programs. DVM
Digital Volt Meter.
dB
Decibel. In electronics and communications,
the decibel (abbreviated as dB, and also as db
and DB) is a logarithmic expression of the ratio
between two signal power, voltage, or current
levels.
E1
E1 (or E-1) is a European digital transmission
format devised by the ITU-TS and given the
name by the Conference of European Postal and
Telecommunication Administration (CEPT). It is
the equivalent of the North American T-carrier
system format. The E1 signal format carries
data at a rate of 2.048 million bits per second
and can carry 32 channels of 64 Kbps each. E1
carries at a somewhat higher data rate than T-1
(which carries 1.544 million bits per second)
because, unlike T-1, it does not do bit-robbing
and all eight bits per channel are used to code
the signal. E1 and T-1 can be interconnected for
international use.

Used to define the gain of an antenna system
relative to an isotropic radiator at radio
frequencies. The symbol is an abbreviation for
"decibels relative to isotropic."

Generally, narrowband describes
telecommunication that carries voice
information in a narrow band of frequencies.
More specifically, a specific frequency range set
aside by the U.S. FCC for mobile or radio
services, including paging systems, from 50 cps
to 64 Kbps.
NMS
Network Management System
ohm
The standard unit of electrical resistance in the
International System of Units (SI). Ohms are
also used, when multiplied by imaginary
numbers, to denote reactance in alternating-
current (AC) and radio-frequency (RF)
applications.
Ohm’s Law
Ohm's Law is the mathematical relationship
among electric current, resistance, and voltage.
oscillator
An electronic device used for the purpose of
generating a signal. Oscillators are found in
computers, wireless receivers and transmitters,
and audio-frequency equipment.
parabolic antenna
An antenna consisting of a parabolic reflector
and a source at or near the focus. A microwave
dish antenna is an example of a parabolic
antenna.
parallel
More than one event happening at a time.
parallel processing
In computers, parallel processing is the
processing of program instructions by dividing
them among multiple processorss with the
objective of running a program in less time.
parity
A technique of checking whether data has been
lost or written over when it has moved from
one place in storage to another or when
transmitted between computers.
polarization
An expression of the orientation of the lines of
electric flux in an electromagnetic field.
Polarization is important in wireless
communications systems. The physical
orientation of a wireless antenna corresponds to
the polarization of the radio waves received or
transmitted by that antenna.
PPP
Point-to-Point Protocol. A protocol for
communication between two computers using a
serial interface.
protocol
In information technology, the special set of
rules that end points in a telecommunication
connection use when they communicate.
QAM
Quadrature amplitude modulation. QAM is a
method of combining two amplitude-modulated
(AM) signals into a single channel, thereby
doubling the effective bandwidth. QAM is used
with pulse amplitude modulation (PAM) in
digital systems, especially in wireless
applications.
QPSK
Quadrature Phase Shift Keying. A digital
frequency modulation technique used for
sending data over coaxial cable networks. Since
it's both easy to implement and fairly resistant
to noise, QPSK is used primarily for sending
data from the cable subscriber upstream to the
Internet.
resistance
The opposition that a substance offers to the
flow of electric current.
RIP
Routing Information Protocol. A widely-used
protocol for managing router information within
a self-contained network such as a corporate
local area network or an interconnected group
of such LANs.
