2. Product Description
2.1 General Description
The Tsunami licensed radios provide high capacity transmission and operational convenience in a digital
communications network.
These Tsunami radios provide 1000BaseF intelligent bridging between two fixed coordinated locations.
Because each owner controls the operation of the link, there is no reliance on any outside services.
Tsunami radio operators are able to operate whenever needed, and to be in control of their own
network.
The Tsunami offers two primary benefits:
v CONVENIENCE Easy to install and operate with a user license
coordinated in the USA. (Other countries may also require
a user license and/or frequency coordination).
v CAPABILITY Full transparent Fast Ethernet connections with no
throughput reduction over any line-of-sight distance (within
legal limits of government regulation)
Tsunami radios are ISO Layer 2 Data Link Layer (use MAC address for filtering) devices where
they provide their full stated throughput. At level 2 (bridges) or 3/4 (routers) where hardware plays
the major part, the most common tester is the SmartBits 200 product from NetCom Systems. At
Application Layer 7, you will see less than 40% throughput from the maximum capacity measured with
SmartBits due to the increased protocol/software overhead at that level. Layer 7 can be tested with
software such as Ganymede's Chariot or Qcheck product (www.qcheck.net/index.html). Use Qcheck (or
equivalent), do NOT use PING for throughput testing (www.qcheck.net/whyqcheck.html)!
As an example: testing copper CAT5e cable with SmartBits will test 100% throughput (let's say you can
send/receive a full 100Mbps). At Layer 7 you will be transferring bits at the 100Mbps rate, but
approximately only 45Mbps of user data will transfer (Ethernet has a high overhead of bytes added to
each data packet frame each time you go up a layer). The advantage is the more complex overhead
makes the data virtually resilient to corruption and minor errors (i.e. collisions), it’s easy to reroute and
the network can use inexpensive plug/play devices like hubs/switches instead of multiplexers as used in
the telco industry (i.e. LYNX T1/E1/DS3 radios)
Western Multiplex tests for stated throughput at Layer 2/3 where bridges are defined. At layer 7
(application layer), you may see less than 50% or more depending on the other traffic that may be on
the LAN as this layer is more dependent on the type of data being sent (it does not matter if it's wire,
fiber or any Ethernet bridge -wired or wireless). Another way to look at it: the model 31145 12Mbps
(10Mbps 10BaseT+T1/E1 wayside) bridge will test the same as a piece of CAT5e Ethernet cable.

2.3.2 Test Points on ODU
The Tsunami radio products do not have an on/off switch.
GND This is a grounding post to connect to earth ground.
RSL This is a test point (BNC connector) that relates to the Received Signal Level (RSL).
The voltage is measured with a voltmeter (using the GND test point for reference)
which corresponds to the actual power level of the incoming received signal.
This is a test point which corresponds to the output transmit power of the radio. The
voltage is measured with a voltmeter (using the GND test point for reference) which
corresponds to the actual power level of the outgoing signal. This measurement is
used during installation, maintenance and troubleshooting
.This voltage only applies to the near-end and does not allow measurement
of the far-end output transmit power, even when the DISPLAY FAR END
button is pressed.
There is a receptacle on the front panel to the right of the LOCAL TX PWR test point
which is an installation adjustment allowing the output transmit power to be
increased or decreased within the radio's specified limits. Using a small screwdriver,
this adjustment is used to set the output power of the transmitter, in accordance to
the path planning.
The Tsunami system requires professional installation. Transmitted output
power limits may apply when using this radio. Consult FCC, IC, Western
Multiplex or other regulatory authorities for limits which may apply. See
Section 3.13.1 for details on setting output power. Do not adjust output
power above factory settings.

2.3.5 Connections
RF CONNECTION
The RF port of this Tsunami radio is an N-type female connector that is used to connect to the ODU
using coaxial transmission line.
Use LDF4-50, LMR-400 or equivalent up to 100 meters (300 ft.)
Use LDF4.5-50, LMR-600 or equivalent up to 300 meters (1000 ft.)
.
DATA CONNECTION
The connection for the Gigabit Ethernet interface that carries the signals in and out of the radio is an SC
type 1000BaseF fiber connection.
DC POWER CONNECTION
The input accepts positive or negative DC power at any voltage between 37 and 63 Volts.
OPTIONAL CONNECTIONS
There are several connections that are not required for operation, but provide additional facilities to the
user.
EOW
VF
This connection is used to access the electronic orderwire function. This is a facility
for "telephone" style service from one radio to another. A standard electronic
telephone [one with a handset and DTMF (push-button tone) dialing] plugs into this
connector. The user can dial the orderwire address of the far-end radio (or any radio
in the Tsunami network) to establish telephone communication between sites. 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.
This connector is used to link two Tsunami radios at a repeater site for Orderwire
operation. This would allow orderwire "telephone" calls to and from any point in the
Tsunami network.
The Tsunami orderwire circuit can also be connected to other existing
orderwire networks. See Section 3.14.1 for details.
ALARM This connector is used for monitoring alarms electrically. The Form C relays can be
connected to other transmission equipment for monitoring alarm status locally or
remotely.
DIAG This is a serial interface port (RS-232) to the Tsunami radio. This port provides
configuration and maintenance information about the Tsunami radio(s) to a

3. Installation & Adjustments
3.1 Shipping Container
The equipment is shipped in boxes unless ordered as an integrated system and configured at the
factory, in which case the equipment may be racked and shipped in a crate. The equipment is
packaged so as to prevent damage in transit.
The boxes should be left intact and sheltered until arrival at the installation site.
If the shipping container shows signs of damage, the transportation
company should be notified immediately. Extra care and inspection
of the contents is advised immediately upon receipt.
It is recommended that all the packaging materials be retained.
In the unlikely event that the equipment must be returned to the
factory, use the original packing materials for return shipment. The
original packaging materials are also recommended for
transporting the equipment from location to location.
Inside the primary shipping containers, internal boxes may contain other items. These boxes should
also be saved for future use.
Also, save the Tsunami radio test data sheet that is provided. The
test data sheet can be placed where the Tsunami terminal will be
installed for future quick reference. All Tsunami units are individually
tested and the actual measured performance recorded on the
Factory Test Data Sheet. You will find this information to be of use
during installation, troubleshooting and maintenance.
A set of “quick installation instructions” is also provided which can be useful for easy reference during
installation.

3.3 Before Installation Task List
There are several tasks that should be accomplished prior to installing the Tsunami radio system. This
section briefly describes the following:
- Site selection
- Line-of-Sight and Path Clearance determination
- Anticipated RSL calculation
- Fade margin calculation
- Availability calculation
- Frequency plan determination
- Power supply planning
- Antenna (and accessories) purchase
Only directional antennas should be used with Tsunami radios.
These are typically flat panel or solid parabolic antennas. Western
Multiplex recommends a maximum beamwidth of 10 degrees for
directional systems.
3.3.1 Site Selection Requirements
The radio site must have:
- access to the appropriate power
- close proximity to the telephone or computer system you wish to interconnect
- line-of-sight to the other radio location with adequate clearance
- location for mounting the antenna

PAGE 3-4 SECTION 3: INSTALLATION & ADJUSTMENTS
3.3.2 Line-of-Sight and Path Clearance Guidelines
The Tsunami radios will not operate properly unless they have line-of-sight between their
corresponding antennas. The Tsunami radio transmission will not pass through trees or other
obstacles. Factors to consider include:
- Earth curvature
- Future growth of trees
- Height of buildings
In addition to the line-of-sight requirement, a well-engineered path will also have additional path
clearance to allow for signal loss due to partial obstructions, atmospheric ducting and ground
reflections. To maximize radio reception, 0.6 times the first Fresnel zone should be calculated and this
distance added to the path clearance (in addition to trees or buildings).

GIGABIT ETHERNET WIRELESS BRIDGES
JANUARY 2001
SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-5
3.3.3 RSL Calculation and Link Budget
The received signal level (RSL) can be estimated using the following formula:
RSL (dBm) = Pout - FL1+ G1 + G2 - FL2 - Lp
where: Pout is the transmitter output power (in dBm)
FL1 is the feeder loss of the transmit side (in dB)
G1 is the gain of the transmit antenna (in dB)
G2 is the gain of the receive antenna (in dB)
FL2 is the feeder loss of the receive side (in dB)
Lp is the Path loss, defined by:
Lp (dB) = 96.6 + 20 log10F + 20 log10D
where: F = Frequency in GHz (2.4 or 5.8)
D = Distance of path in miles
This link budget is very important for determining any potential problems during installation. If you
have calculated the expected RSL, you can see if it has been achieved during installation, and
troubleshoot if necessary.

PAGE 3-6 SECTION 3: INSTALLATION & ADJUSTMENTS
3.3.4 Fade Margin Calculation
The fade margin is the difference between the actual received signal and the radio’s threshold. Using
the formula provided in Section 3.3.3, the anticipated RSL can be calculated. Compare this RSL to the
specified threshold of the Tsunami radio (shown in Section 2.2) and calculate the fade margin as the
difference between the two signal levels.
3.3.5 Availability Calculation
Availability of the microwave path is a measure of the percent of the time that the link will operate
without producing an excessive BER due to multipath fading. In the absence of direct interference,
availability is affected by the following:
- Path length
- Fade margin
- Frequency (5.8 GHz in the case of these Tsunami radios)
- Terrain (smooth, average, mountainous)
- Climate (dry, temperate, hot/humid)
Depending on the type of traffic carried over the link, the system designer may wish to design for a
specific availability. For example, if the data or voice traffic that is carried by the radio is critical then it
may be designed for a very high availability (e.g. 99.999% or 5.3 minutes of outage per year). To
improve availability, for example, the fade margin can be increased by making the path shorter, or by
using higher gain antennas.

The Tsunami radio must have access to a supply of appropriate DC power. The Tsunami can be
powered from a DC battery system, or from a solar or generator power plant, usually with battery
reserves. Typically either a positive or negative 48 volt supply is used. For DC, be sure the cable is of
sufficient gauge to carry the necessary current and it is less than three (3) meters (9.75 feet) in length.
Before installing the radio, plan for the continuous power consumption needs in accordance with the
specifications given in Section 2.2 of this manual. It is also wise to plan for backup power for critical
communication circuits (including the Tsunami radio). Backup power allows the radios and associated
equipment to continue operation when primary power is interrupted.
3.3.7 Antenna Planning
Using path planning mathematics, proper antenna size can be determined which will yield the desired
path performance. In general, the larger the antenna that is used with the Tsunami radio, the better
the link will perform. Larger antennas have narrower beamwidth and higher gain, which will yield better
link performance (higher fade margin, better availability) and improve immunity to interference (due to
the smaller beamwidths). However, larger antennas are more costly to purchase and install than
smaller antennas, in some cases requiring special equipment for installation. All of these factors
should be taken into consideration when selecting antennas.
In areas where transmitted output power restrictions apply, the use
of larger antennas will maintain the benefit of narrow beamwidths
and receive gain. However, output power may need to be reduced to
meet regulations. (See Section 3.13.1)
Prior to installation, the specific antenna location and mounting should be determined. This advanced
planning also yields the transmission line requirements.
Only dual-band/dual-polarized directional antennas can be used
with these Tsunami radios.

3.6 Mounting the Tsunami Radio
The Tsunami radio can be mounted at any height in a standard 19-inch rack. Blank rack-mounting
spaces above and below the Tsunami are recommended, especially if the surrounding equipment
dissipates a considerable amount of heat.
The Tsunami radio may be set up for mounting with the front edge projecting from the front face of a
standard 19-inch rack using the rack mounting brackets enclosed with the screws in the Accessory Kit
(4 per bracket). The rack mounting brackets may be reversed, in order to install for flush or cabinet
mounting if preferred. Depending on rack configuration, it may be necessary to remove the four
adhesive backed rubber feet on the bottom of the unit.
The Tsunami radio has internal fans which intake and exhaust on
the left and right sides of the chassis. When rack mounting, it is
important to leave a small gap between the outer edges of the
radio and the inside edge of the rack.
The Tsunami radio may alternatively be placed on a table or shelf
attached to a wall. Because of the low weight of the Tsunami, any
mounting option other than rack mounting will be less secure.
The ODU is mounted on a substantial mounting pole (minimum 2.5 inches) to accommodate the
supplied mounting bracket.

3.7 Power Connection and Wiring
There is no ON/OFF switch on the Tsunami. As soon as
power is applied, the equipment will be operational. This
means that there can be up to 1W of RF power present at the
antenna port. The antenna port should be terminated before
power is applied.
Power is connected using the DC power plug contained in the Accessory Kit. Use Table 3-B or 3-C
along with the associated diagram of Figure 3-3 or 3-4 to connect the DC power cables. For example,
for a negative DC power input, use Table 3-B and Figure 3-4.

3.7.1 DC Power Wiring
Connect the power cable with adequate current rating (minimum of 20 AWG) to the terminals shown
on the removed (not plugged into the radio) DC power plug using the screw connections. The
recommended minimum current rating of external fuses and cables is 5 Amps. The Tsunami radios
consume less than 4 Amps at ±48V. Be sure the DC power cable is less than 3 meters (9.75 feet) in
length.
Each Tsunami terminal should be externally fused separately with
a 8 Amp maximum fuse. The DC power cable must be less than
three (3) meters in length.
If using negative power, connect the negative voltage to pins 1 or 6. Connect the ground return
connection to pins 3 or 4. See Figure 3-3.
If using positive power, connect the positive voltage to pins 3 or 4. Connect the ground return
connection to pins 1 or 6. See Figure 3-4.
The ground connection is available at pins 2 and 5. Either pin may be used to ground the return side
of the power supply. Do not ground both sides of the power supply.
Proper grounding, either through the chassis and/or the power
supply, can be very important for protection from lightning. A
grounding screw hole is provided on the rear panel.
The ground connection may be left floating if the power supply is
referenced to ground externally and to avoid ground loops in some
configurations. However, this may not provide adequate grounding
for lightning protection.
Use a DVM (digital voltmeter) to verify voltage and polarity on the DC power plug.
Do not connect the DC power plug to the rear of the Tsunami
terminal until a load is connected to the antenna port (either an RF
pad, or an RF cable and antenna).

3.8 Antenna Installation & Alignment
The antenna installation consists of permanently mounting the antenna and then attaching the ODU
mounting plate and then the ODU itself to the mount. The antenna and ODU 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 general, antennas smaller than 1.5 feet diameter are not recommended for
urban.
Antennas should be ordered with the suitable mounting kit specific to the site requirements. The
antenna must be 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. The mounting kit includes the details on how to mount and adjust azimuth and tilt. Here,
the details on how to mount the adapter plate and ODU are described.
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 whole 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 Tsunami radios are required to align the
antennas. The antenna is coarse aligned using visual sighting and then fine aligned using the receive
signal level (RSL) voltage of the Tsunami. See figure 3-8.
The RSL voltage reading can still be used to peak antennas even if
the radios have not synchronized, however far-end RSL cannot be
measured from the near-end terminal until radios are synchronized.
INSTALLER CAUTION: Antennas used for this device must be fix-mounted
on permanent outdoor structures to provide 5 meter or more separation from
all persons during device operation to comply with FCC and other regulatory
RF Exposure requirements. Installers should contact the manufacturer for
applicable antenna gain and type restrictions to ensure compliance.

After attaching the mounting plate, use the antenna in either the horizontal or vertical polarization
position (remember, both ends of the link MUST use the same polarization).
Note: the A and B feed coax cables must be used for horizontal or
vertical polarization with the ODU.
After mounting the antenna, attach the dual coax cables that connects the ODU with the IDU.

3.8.2 Course Antenna Alignment
To coarse-align the antenna, first set it for flat elevation (no up or down tilt) using a spirit level. Then
point it 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 a heading marker cannot be set sufficiently far away (for example when on a city building roof or
looking through a window) then a rough azimuth setting can be obtained by sighting along the antenna
feed.
It should be verified that both antennas are on the same polarization
by using the manufacturer’s instructions. Otherwise the RSL will be
approximately 25 to 30 dB below the calculated level.
Most antennas will also need fine alignment obtained using an operating link because it is very
important to maximize the receive RF signal level at each end of the radio link.
Read Section 3.7 before applying DC power to the Tsunami radio.
Once the coarse alignment has been set-up at both ends, then the link can be powered and some
level of reliable communication established. The voltage at the Tsunami ODU RSL test point (BNC
connector) should be measured with a DVM to determine the relative receive RF signal level.
For the fine alignment, adjusting first the azimuth and then the elevation of the local antenna will
maximize the RSL voltage. Then, the far antenna is aligned in the same way, using the RSL voltage of
its local Tsunami radio ODU.
When aligning antennas it may be convenient to allow direct visiblity to the technicians aligning the
antenna.
An orderwire telephone will provide end-to-end voice communications
once radios are synchronized. Synchronization usually can be
accomplished by coarse alignment only. After synchronization, the
orderwire phones can be used to communicate between radio sites for
antenna fine alignment. 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, 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.
The graph shown in Figure 3-8 shows the typical variation of RSL voltage as the receive signal level is
increased from threshold to a higher level. There is some variation between Tsunami receivers, but an
approximate estimate of the potential RSL value may be made using this figure.
Use the Factory Test Data Sheet shipped with your Tsunami terminal to
obtain the best estimate of your RSL.

SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-19
Above 0 dBm RSL, the receiver may produce errors: however this level is rarely likely to be exceeded.
A link budget calculation should be made to calculate the anticipated RSL as described in Section
3.3.3. During anomalous propagation conditions, the RSL may fade but will not increase up more than
10 dB (except in unusual very long paths which may fade up by 15 dB).
Antenna alignment should enable the RSL to be peaked to the level
calculated in the link budget. If the RSL is peaked but is
approximately 20 dB below the calculated level, then it is likely that
the antennas are aligned on a sidelobe of the antenna's radiated
signal. In this case, the antennas should be rotated in a wide arc until
the main lobe is located. (Other possible causes of low RSL are path
obstructions, loss in connectors, adapters and pigtail jumper cables
or different antenna polarization at each end of the link.)

3.10 System Turn-up to Service
1. Prior to installing the system, it may be desirable to perform a back-to-back test of the Tsunami
radio pair. Consult Section 4.9 for further details. Back-to-back testing is a simple way to verify
that the Tsunami radios are fully operational before they are installed. Installation adds several
variables (such as antenna alignment) which can lead to system turn-up delays. Also, during
back-to-back testing, the DIP switch settings and some connections can be tested. This step
can eliminate a majority of troubleshooting once the radios are installed.
A cellular phone or two-way radio system (walkie talkie, CB,
mobile radio) can be very useful during installation. These can
be used for temporary near-end and far-end communications
between the installation personnel at one site and installation
personnel at the other site while installing the system. These can
also be helpful for communication between a person at the top of
a very tall tower and ground personnel.
The Tsunami radio incorporates an internal Orderwire feature
that provides end-to-end “telephone” style communications.
However, the link must be partially operational to use this feature.
In lieu of, or in addition to the use of cellular phones or two-way
radio, this Orderwire feature can also be very useful for
installation, but typically cannot be put into service until step 8 or
9 of this procedure is completed. See Section 3.14.1 for more
details.
2. Perform a general alignment of the antennas on both ends of the path using binoculars,
compass or other related tools. It is important to have the antennas aligned as accurately as
possible before putting radio traffic over the link. This will help in getting the system running
more rapidly. See Section 3.10 for more details.
3. Connect the transmission line to the antenna, and feed it to the Tsunami radio location (see
Section 3.9). Connect the opposite end of the transmission line to the N-type female
connector located on the filter assembly which occupies the top half of the Tsunami rear
panel. The connection must be terminated into an antenna or a load before DC power is
applied to the radio.
4. Verify that the same channel plan (e.g. A, B) as the near-end radio, and the opposite Tx and
Rx frequencies (e.g. A1 and A2 make up a matched pair of radios).
5. With the DC power source active, but not plugged into the Tsunami radio, using a voltmeter,
confirm that the DC mating connector has the proper power connections in accordance with
Section 3.7. Verify the polarity and the absolute voltage on all pins. Verify ground connection
for power.
6. Connect power to the Tsunami radio. Verify that the Front Panel “ON” LED indication is
illuminated. This confirms that power has been properly applied.
Ensure that the RF Antenna port connection is properly terminated
before applying power to the Tsunami terminal, as in step 3.

When the Tsunami radio is initially powered-on, some alarm
conditions may be present. This is normal and alarms can be
ignored at this time.
The Tsunami radio requires professional installation. With some
Tsunami models, in certain countries, there may be Effective
Isotropic Radiated Power (EIRP) limits which dictate the maximum
output power that the Tsunami radio can transmit given the
transmission line loss and the gain of the antenna. Consult with
appropriate government agencies or Western Multiplex if there is
any question regarding maximum output power allowed. Do not
adjust output power above factory settings.
7. Connect a voltmeter to the ODU’s test points (BNC connection). This voltage reading
corresponds to the Received Signal Level (RSL) of the near-end radio. In other words, RSL is
the “amount” of signal the near-end radio is receiving from the far-end radio. Since the
antennas have not been finely aligned, it is not expected at this time that the RSL will read
very high. However, at this point it can be verified that some communication is taking place
between the two Tsunami terminals. Use the RSL voltage reading to align the antennas. Align
one antenna at a time in accordance with Section 3.10. Complete alignment of both ends of
the radio link before going further.
The RSL voltage output on the radio's front panel will output a
voltage over the usable range of the radio. Refer to Figure 3-8 in
Section 3.8.2.
RSL of both ends should be verified to be within approximately 2 dB of predicted value (see
Section 3.3.3). There are several factors that can contribute to low RSL:
-Incorrect antenna alignment (aligned on a lobe and not on the main signal)
-Improper polarization alignment of antennas (horizontal vs. vertical)
-Transmission line problems (loose connections, bent or damaged cables, lossy
adapters)
-Path obstructions (trees, buildings, hills, etc.)
-Path clearance (line-of-sight, earth curvature, Fresnel zone, diffraction and partial
obstruction)
-Weather (inversion layers, ducting and multipath)
- Antenna feed (coaxial/connector) problem

Tsunami FAMILY
GIGABIT ETHERNET WIRELESS BRIDGES

SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-23
The Tsunami radio requires professional installation. Don’t forget
that the transmitter output power adjustment on the Tsunami radio
effects the RSL. Depending on 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 radios in service.
If radio synchronization has been established, the radio link may
be able to provide some limited communications over the link. It
can be helpful to establish voice communications from one end of
the radio link to the other using the Orderwire feature of the
Tsunami radio. See Section 3.14.1 for details.
If RSL is lower than anticipated, recheck the path clearance and transmission line as these are the
typical causes of low RSL. Radio operations can be verified by connecting radios back-to-back with
attenuators (40-60 dB), (see Section 4.9). If the problem remains, consult Section 4 of this manual for
troubleshooting techniques which will help determine the source of the problem.
8. Once radio performance is verified and acceptable, the Tsunami radios can now be put into
service with the intended Gigabit Ethernet traffic. Connect to the LAN or computer using the
SC (fiber) 1000BaseF connector. With Ethernet traffic applied in both directions, all front
panel LEDs, except for POWER and the data TXD/RXD lights should be off. If any other
LEDs are on, consult the trouble shooting sections of this manual.
9. Now that the link is operational, other services can be connected including T1 (DSX-1),
Orderwire, Diagnostics, Alarms and Aux Data (Service Channel). Consult Section 3.14 for
details on these connections.

3.11 Additional Connections
There are additional customer connections which are optional and are not required to make the
Tsunami operational but may prove useful.
3.11.1 Orderwire Connection
Orderwire is a “telephone” type wayside service which allows users of the Tsunami radio to establish
voice communications from one radio to another, either directly to the companion far-end, or through
a repeater configuration, or several repeater configurations.
Telephone connection specifications:
REN (Ringer Equivalency Number) 1.0 B
DTMF tones within ±1.5% of nominal freq.
Ringing Voltage 48 VDC, typical
(Ringing voltage is adequate for modern solid state ringers,
NOT for the older mechanical type ringers)
This Orderwire service does not affect the normal radio transmission of traffic. Refer to Section 2.3.5
for the telephone specifications. For simple near-end to far-end communications, follow the steps
below:
1. Using a standard RJ-11 telephone cable, connect a standard electronic telephone (a touch
tone phone, complete with dialer; a handset by itself will not work) to the Orderwire connector
on the Tsunami front panel. This connector is wired identically to a standard two-wire
telephone jack, see Figure 3-9 for details.
2. With a telephone connected to each Tsunami terminal on opposite ends of the link, either
telephone can be used to “dial-up” the far-end location. The far-end terminal’s internal ringer
and the connected telephone will ring, and if answered, two-way full-duplex voice
communication is established.
If using the Orderwire or Network management functions, all
Tsunami radios connected must have unique address settings
(telephone numbers).
4. If the Tsunami radios are connected in a repeater configuration, Orderwire services can be
established to all Tsunami terminals in the network by implementing a connection of their rear-
panel connectors between repeater terminals. At the repeater site, a cable can be connected to
the two Tsunami terminals between their rear panel VF 9-pin connectors as shown in Figure 3-6.
With this cable in place, the Orderwire function will operate at terminals at each end of the
repeater and at the repeater site. This function can be continued through several repeater sites if
desired. For hub connections of 3 or more Tsunami radios at the same site, an external 4-wire
bridge is required to connect all radios to the orderwire.
The orderwire system can be integrated with orderwire equipment
supported by many other vendors. If your existing orderwire

network uses 2 digit addressing, and 0 dBm VF interface, it can be connected
to a Tsunami as shown in Figure 3-9.
Dialing a V (star key) on the orderwire telephone implements an “all call”
feature which rings all connected radios. Also, if a phone anywhere in the
connected network has accidentally been left off-hook, the # (pound key) key
can be used to mute all off-hook handsets until they are placed on and off
hook again.
The orderwire operates like a “party line”. 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.

radio prior to installation. If IP addresses and security are set properly, the connection can also be
used as an out-of-band connection for radio management. Alternatively, if the 100BaseT/F is
connected to a network, or combined with the 100BaseT traffic on the link, via an external 10/100
switch, hub or router, full wireless NMS can be achieved for all radios in the network.
The factory default IP address is set to 10.0.0.1. To reset the radio back to the factory default, Hold
down the far-end test button while powering up the radio. Release the switch after 6 seconds.
More details on the NMS connection can be found in Section 4 of
this manual. In the future, this connection will also allow NMS via
SNMP (Simple Network Management Protocol) in addition to the
HTML interface that is presently supplied. Consult factory for
details or assistance with NMS connections, if required.
Ethernet Cable:Straight version to hub/switch, crossed version direct to PC.

4.1 Regular Maintenance
The Tsunami radios do not require any regular maintenance, however, it is prudent to monitor the
radio link at regular intervals to assure that the link conditions are not changing. When visiting a
radio site for maintenance, the following items may be checked and their results recorded:
vRSL Voltage
vPWR Voltage
vFar-end RSL Voltage
vAlarm conditions
vVerify radio has adequate ventilation
vVerify security ID is set the same at each radio through NMS
If any alarm conditions exist, they should be recorded, and troubleshooting procedures from this
Section of the manual should be followed.

4.3 Repair Policy
The Tsunami terminal includes comprehensive alarm indicators designed to diagnose potential
faults. Should a fault occur, it often may be resolved by operator adjustment.
Should a fault occur that cannot be resolved by operator adjustment and has been confirmed by
looping terminals together on the bench (See Section 4.7), then the equipment should be returned
to the factory for repair.
The Tsunami radio is a complex system not designed for user repair. Do not remove the cover or
open any part of the Tsunami terminal. The complete Tsunami terminal should be sent back in its
original packing material for factory repair.
Please 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 be delayed in the processing of the repair. Be sure to include the following
information:
vRMA number
vdescription of the problem
vyour name and telephone number
vreturn shipping address
vurgency of repair
Please refer to the published Warranty policy for repair policy
details.
Tsunami radios should be packaged in their original packing
boxes for shipment whenever possible Western Multiplex can
provide an empty box shipment to facilitate proper packaging.
Regardless, proper and adequate packaging must be used for
shipments to protect the radio(s) from damage. Western
Multiplex can not be held responsible for any repairs due to
inadequately packed materials. Damage caused by improper
packing will likely result in higher repair costs and delays (refer
to the Warranty section at the beginning of this manual).

4.4.1 RF LINK Alarm
Function:
This LED indicates that the demodulator function is not synchronizing with the intended received
signal.
Possible Causes:
vSevere path fading due to atmospheric conditions, usually accompanied by low RSL
voltage reading
vPoor transmission line connections usually accompanied by low RSL voltage reading
vAntenna problems, misalignment, or path clearance usually accompanied by low RSL
voltage reading
vImproper radio settings (e.g. frequency channel)
vReceived signal level (RSL) is too strong
vInterference
vFar-End radio transmitter circuitry is faulty
vNear-End radio receiver circuitry is faulty
vLink security ID not the same for each radio
Recommended Actions:
Check the following at each end of the link:
vVerify that rear panel filters are opposite channel plans on each end (e.g. one is A1 and
other is A2).
vVerify that radio frequency settings match each installed filter (in NMS menus).
vVerify 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. Compare this voltage to
the Factory Test Data Sheet and estimate the RSL in dBm. Compare this to the RSL that was
expected using path calculations (see Section 3.3.3). Press and hold the DISPLAY FAR END
button and measure the far-end RSL (while continuing to hold the button). Compare this RSL to
the Factory Test Data Sheet for the far-end radio and estimate the RSL in dBm. Again, compare
this RSL to the expected RSL from the link budget calculations.
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(s) 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). Antenna alignment, line-of-sight and path clearance should
be verified; if this does not improve RSL, all devices between the radios and their antennas at
both ends should be checked. Make sure all transmission line, connectors and any other devices
are properly rated for operation at the radio's frequency (5.3/5.8 GHz).

PAGE 4-6 SECTION 4: TROUBLESHOOTING
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, this
can be connected to the RF output of the radio for precision measurement. This test will also
verify 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.
To verify the possible presence of interference, remove DC power to the radio which is opposite to
the one that is reading high RSL. Once power is removed, measure RSL on the remaining radio.
If RSL voltage is lower than that which is listed for "Threshold" in the Factory Test Data Sheet,
then 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 Section 4.2 for details. Swap terminals at
both ends of the link so that they are the opposite from their original installation. After both ends
are moved, reconnect the radios and determine if the BER alarm is still active. If the BER alarm is
still active, other frequency channels can be installed, or other interference countermeasures can
be tried, in accordance with Section 4.8.
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. While radio failure is typically 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 will verify proper radio operation. See
Section 4.9 for details. 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.
(See Section 4.7).
If the radios successfully pass their back-to-back testing, the problem is likely with the path or the
connections between the radio and the antenna or interference. Before reinstalling the radios, be
sure to set the output power to the appropriate level for the installation.

4.4.2 RADIO FAIL Alarm
Function:
The RADIO FAIL alarm indicates a known problem with the radio hardware.
Possible Causes:
vInternal synthesizers are unlocked
vInternal digital circuits have failed
Recommended Actions:
1. Remove power from the unit.
2. Check to make sure power supply voltages are within specification.
3. Even if the voltages were within specification, reapply power to the unit.
4. If RADIO FAIL alarm clears, place the radio back into service.
5. If RADIO FAIL alarm does not clear, perform a back-to-back test to verify radio operation, as
described in Section 4.7.
6. If RADIO FAIL alarm is still active in a back-to-back test, return the radio to the factory for
repair (see Section 4.3).

4.5 Errors in the Data Stream
When the radio is in service, errors in the data stream may occur. This is usually known to the
operator by either faulty data indications of downstream equipment or external bit error rate
testing.
It is possible that no alarms appear on the front panel during normal operations, but there are
errors present in the data stream. Some errors will not result in no alarm (such as bipolar
violations, slow "dribbling" errors, improperly terminated connections or incorrect settings), but will
be 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:
vDuring external BER test, test equipment indicates errors
vDownstream equipment (mux, channel bank, CODEC, router, etc.) indicates errors
Possible Causes:
vPath fading due to atmospheric conditions
vPoor transmission line connections
vAntenna problems, misalignment or path clearance
vReceived signal level (RSL) is too strong
vFar-End radio transmitter circuitry is faulty
vNear-End radio receiver circuitry is faulty
vInterference
Recommended Actions:
1. Verify 1000BaseF fiber connection and cable.
2. Follow the instructions described in Section 4.4.1

4.6 Back-to-Back Testing
Back-to-back testing, as shown in Figure 4-1, is an ideal method of testing the Tsunami radios.
This testing eliminates link problems caused by auxiliary equipment, installation, or the radio path
and isolates potential radio hardware problems. Back-to-back testing must be performed with both
radios at the same location. The following test equipment is required:
vDC power source capable of supplying approximately 250 Watts (total) to the radios.
vTwo coax couplings and 70dB loss attenuation per cable.
vBER tester
Back-to-back testing must be performed to verify a radio
problem before returning any radio to the factory for repair.
Use two coax cables and approximately 70dB attenuation per
cable
When the equipment is connected as shown in Figure 4-1, both Tsunami radios should have no
alarm conditions. If these conditions have been met, then it is likely that the Tsunami radio is
operating in accordance to specifications. If errors or alarms occur during this test, verify that all
configuration settings are properly set. If alarms or errors are still present, the radio is likely to be
faulty.

4.7 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). Figure 4-2 illustrates
a typical test configuration (which may include the radio’s path instead of in-line attenuators).
Figure 4-2 illustrates a typical test configuration for end-to-end testing.
When performing testing, make sure of the following:
- Disconnect all 1000BaseF inputs and outputs to both radios.
- Verify all configuration settings.
Link testing may be performed on the bench, with two terminals back to back, or over the radio
path. Also, it may be performed from end-to-end (which requires two 1000BaseF test sets over a
link, the far-end unit slaved to the near-end unit’s clock) or in loopback mode)
If link testing indicates an unacceptable level of errors, follow the instructions in Section 4.4.1. or
perform a back-to-back test.

4.8 Network Management System (NMS)
The Tsunami 1000BaseF radio platform provides multiple methods of managing the radio
network:
1) SNMP
2) Browser (IE, Netscape, etc.) graphical user interface
3) Software upgrade procedure
4) TelNet (via VT100 session using Windows Hyperlink)
4.8.1 SNMP
Use your favorite SNMP access software such as HP OpenView. Please contact customer
service/support to get a copy of the MIB file e-mailed to you or from our FTP site.
4.8.2 Browser GUI
Use Internet Explorer™ or Netscape™ to access the radio by typing in its IP address. If you are
setting up the radios for the first time, the default IP address is: 10.0.0.1 You will have to configure
your computer to this domain first by setting its address to 10.0.0.5 and then changing the radio’s
IP to one within the domain of your network. After changing one radio’s IP address (see
Configuration tab) change the other radio’s IP address also, but not to the same address of the
previous radio. Reconfigure the IP address of your computer to it’s original address and then
restart the PC so it is now in the same domain as the radios.
The browser interface shows a “virtual” front panel of the radio that is addressed. To view the front
panel of the associated far-end radio, click on the window that is located on the virtual front panel
(see following illustrations). Illustrations on the next few pages of this manual provide details on all
browser screens and operations.
4.8.3 In-band NMS Set-up
Use a 4-port (or larger) 100/1000 switch (recommended as opposed to a hub that will also work)
at each radio to operate the NMS in-band with the 100BaseT/F traffic. The NMS port can have a
unique domain that is valid only with the PC that is being used for network management and
system-wide operational status and will not interfere with 100BaseT/F traffic as the radio's MAC
address plus its IP address are unique.
Radios are set at the factory to IP addr: 10.0.0.1. Temporally set your PCs domain (write down its
present IP address) to a suggested setting of PC=10.0.0.5-the PC will force a re-boot. Re-boot
the PC computer attached to the first radio's 100BaseT NMS port and log-in to radio NMS
w/favorite browser (IE or Netscape) after log-in (manager:manager). Change the IP address
(Configuration) to an unused one in your domain (if you want to also change the password at this
time, do this first). Do the same with other radio (may have to reboot computer attached to this
other 10.0.0.1 radio as the other's MAC address does not match the MAC/IP address the PC
knows about). Set the IP address this radio to a different IP address in your normal operating
domain. Set your PC back to its original domain (will force reboot again). This should allow for
typical LAN operation. Type http://10.0.0.1/index.htm to gain initial access.

The radio has two banks of flash memory available, Bank 0 and Bank 1, only one bank will be in
use at a time. The radio will automatically utilize the new uploaded bank.
In addition, through the procedure, you can also manually select Bank 0 or Bank 1 by selecting
the (switch) button. Switching between Banks is quick and you will need to re-start the browser.
Also, to determine if a flash memory Bank has any software, you can read the Bank status. E.g.
Valid or invalid, invalid indicating that it is an empty memory Bank.

Use a standard TELNET session (i.e. Windows Hyperlink). Program will emulate a VT100
monitor. Plug into the radio’s CONFIGuration port.
Set the session to an unused COM port (e.g. COM1) and use 19,200 baud, 8 bits, No parity and
One stop bit. Cable is two (2) DB-9F connectors with pins 2-3, 3-2 and 5-5 using 3 conductor wire.
To start a session (type what is within the single quotes and then the Enter key):
Hit the PC’s CR/Enter key two (2) times after the radio has reinitialized
Type ‘1’ and CR/Enter to enter the User Name and then Enter key (factory default=manager)
Type ‘2’ and CR/Enter to enter the Password and then the Enter key (factory default=manager)
Type ‘a’ and Enter Key to accept the two entries - you should now see a menu list (a=accept)
Any time you wish to go back to a previous screen, type ‘o’ for out (if an ‘o’ does not exit from the
page you working from, use ‘logout’ to exit).
There are many user changeable functions that may not be present in the browser such as setting
the “Default Gateway” if the radio’s NMS port is connected through a router.
As an example, the following steps can be used to check the radio’s Network Status:
From the NMU Main Menu, type 3 and Enter.
Note the radio’s IP address, subnet mask, MAC address and other radio parameters.
Example 2: Set a Default Gateway:
From the main menu (after logging in), type ‘11‘ to get to the VxWorks Shell prompt (->).

Appendix B – Networking Q&As
Q: What is Ethernet?
A: Ethernet is a type of network cabling and signaling specifications (OSI Model layers 1
[physical] and 2 [data link]) originally developed by Xerox in the late 1970. The IEEE's
(Institute of Electrical and Electronics Engineers) used Ethernet Version 2 as the basis for the
802.3 CSMA/CD network standard.
Q: What is an 802.3 network?
A: That's IEEE-ish for Ethernet.
Q: What is CSMA/CD?
A: CSMA/CD is the media access control mechanism used by Ethernet and 802.3 networks;
in other words, it determines how a packet of data is placed on the wire. CSMA/CD
stands for "Carrier Sense Multiple Access, with Collision Detection". Before an Ethernet
device puts a packet "on the wire", it listens to find if another device is already
transmitting. Once the device finds the wire is clear, it starts sending the packet while also
listening to hear if another device started sending at the same time (which is called a
collision). Refer to the Q&A on collisions for more info about this phenomena.
Q: What is an OSI Model?
A: The Open Systems Interconnect (OSI) reference model is the ISO (International
Standards Organization) structure for the "ideal" network architecture. This Model outlines
seven areas, or layers, for the network. These layers are (from highest to lowest):
LAYER
7) Applications: Where the user applications software lies. Such issues as file access
and transfer (FTP), virtual terminal emulation, Internet connections (HTTP), inter-
process communication and the like are handled here.
6) Presentation: Differences in data representation are dealt with at this level. For
example, UNIX-style line endings (CR only) might be converted to MS-DOS style
(CRLF), or EBCIDIC to ASCII character sets.
5) Session: Communications between applications across a net- work is controlled at
the session layer. Testing for out-of-sequence packets and handling two-way
communication are handled here.
4) Transport: Makes sure the lower three layers are doing their job correctly, and
provides a transparent, logical data stream between the end user and the network
service s/he is using. This is the lower layer that provides local user services.
3) Network: This layer makes certain that a packet sent from one device to another
actually gets there in a reasonable period of time. Routing and flow control are
performed here. This is the lowest layer of the OSI model that can remain ignorant of
the physical network.

SECTION 5: APPENDICES PAGE 5-3
2) Data Link: This layer deals with getting data packets on and off the physical layer,
error detection and correction and retransmission. This layer is generally broken into
two sub-layers: The LLC (Logical Link Control) on the upper half, which does the error
checking, and the MAC (Medium Access Control) on the lower half, which deals with
getting the data on and off the physical layer (wire, fiber and Tsunami Wireless
Bridges).
1) Physical: The nuts and bolts layer. Here is where the cable, fiber, radio, connector
and signaling specifications are defined.
Q: What does an Ethernet packet look like?
A. See the information below, as described in the National Databook. The Ethernet packet
preamble is normally generated by the chipset. Software is responsible for the destination
address, source address, type, and data. The chips normally will append the frame check
sequence.
+------------+
| | Preamble –
| 62 bits | A series of alternating 1's and 0's used by the
| | Ethernet receiver to acquire bit synchronization.
| |
+------------+
| | Start Of Frame Delimiter –
| 2 bits | Two consecutive 1 bits used to acquire byte
| | alignment.
+------------+
+------------+
| | Destination Ethernet Address –
| 6 bytes | Address of the intended receiver.
| | The broadcast address is all 1's.
+------------+
| | Source Ethernet Address –
| 6 bytes | The unique Ethernet address of the sending
| | station.
+------------+
| | Length or Type field –
| 2 bytes | For IEEE 802.3 this is the number of bytes of
| | data.
+------------+
| 46 bytes | Data –
| to | Short packets must be padded to 46 bytes.
| 1500 bytes |
+------------+
+------------+
| | Frame Check Sequence(CRC) -
| 4 bytes | The FCS is a 32 bit CRC calculated using
| | the AUTODIN II polynomial.
+------------+
The shortest packet is: 6 + 6 + 2 + 46 = 60 bytes The longest packet is: 6 + 6 + 2 + 1500
= 1514 bytes
Q: What is a MAC address?
A: It is the unique hexadecimal (numbering base 16) serial number assigned to each
Ethernet network device to identify it on the network.. With Ethernet devices (as with most
INSTALLATION AND MAINTENANCE MANUAL
Tsunami FAMILY
GIGABIT ETHERNET WIRELESS BRIDGES
JANUARY 2001
PAGE 5-4 SECTION 5: APPENDICES
other network types), this address is permanently set at the time of manufacturer, though
it can usually be changed through software (though this is generally a Very Bad Thing to
do).
Q: Why must the MAC address to be unique?
A: Each communicating end device (not bridges) has a unique MAC address, so that it will
be able to exclusively grab packets off the network meant for it. If MAC addresses are not
unique, there is no way to distinguish between two devices. Devices on the network watch
network traffic and look for their own MAC address in each packet to determine whether
they should decode it or not. Special circumstances exist for broadcasting to every
device.
Q: Is there a special numbering scheme for MAC addresses?
A: The MAC addresses are exactly 6 bytes in length, and are usually written in hexadecimal
as 12:34:56:78:90:AB (the colons may be omitted, but generally make the address more
readable). Each manufacturer of Ethernet devices applies for a certain range of MAC
addresses they can use. The first three bytes of the address determine the manufacturer.
RFC-1700 (available via FTP) lists some of the manufacturer-assigned MAC addresses.
A more up-to-date listing of vendor MAC address assignments is available on
ftp.lcs.mit.edu in pub/map/Ethernet-codes.
Q: What does CRC mean?
A: Cyclical Redundancy Check - A method of detecting errors in a message by performing a
mathematical calculation on the bits in the message and then sending the results of the
calculation along with the message. The receiving work-station performs the same
calculation on the message data as it receives it and then checks the results against
those transmitted at the end of the message. If the results don't match, the receiving end
asks the sending end to send again.
Q: What do 10Base5, 10BaseT, 10Base2, etc mean?
A: These are the IEEE names for the different physical types of Ethernet. The "10" stands
for maximum signaling speed: 10MHz. "Base" means Baseband. 10BaseT, where the T
means twisted pair, and 10BaseF where the F means fiber (see the following Q&A for
specifics). This actually comes from the IEEE committee number for that media.
In actual practice:
10Base2 Is a maximum of 10MHz Ethernet running over thin, 50 Ohm baseband coaxial
cable. 10Base2 is also commonly referred to as thin-Ethernet or Cheapernet. 10Base5 is
10MHz Ethernet running over standard (thick) 50 Ohm baseband coaxial cabling.
10BaseF is Ethernet running over fiber-optic cabling. 10BaseT is Ethernet running over
unshielded, twisted-pair cabling.
Q: What is UTP?
A: Twisted pair cables. UTP is for Unshielded, Twisted Pair, while STP is for Shielded,
INSTALLATION AND MAINTENANCE MANUAL
Tsunami FAMILY
GIGABIT ETHERNET WIRELESS BRIDGES
JANUARY 2001
SECTION 5: APPENDICES PAGE 5-5
Twisted Pair. UTP is what's typically installed by phone companies (though this is often
not of high enough quality for high- speed network use) and is what 10BaseT Ethernet
runs over. UTP is graded according to its data carrying ability (e.g., Level 3, Level 4, Level
5). 10BaseT Ethernet requires at least Level 3 cable. Many sites now install only Level-5
UTP (CATegory 5), even though level 4 is more than sufficient for 10BaseT, because of
the greater likelihood that emerging high-speed standards will require cable with better
bandwidth capabilities.
Q: Are there any restrictions on how Ethernet is cabled?
A: Yes, there are many, and they vary according to the media used. First of all, there are
distance limitations: 10BaseT generally accepted to have a maximum run of 100-150M,
but is really based on signal loss in dB's (11.5db maximum loss source to destination).
Then there are limitations on the number of repeaters and cable segments allowed
between any two stations on the network.
The rule is, any possible path between two network devices on an unbridged/unrouted
network cannot pass through more than 4 repeaters or hubs, nor more than 3 populated
cable segments. 10BaseT and 10BaseF are star-wired, so there is no minimum distance
requirement between devices, since devices cannot be connected serially. You can install
up to the Ethernet maximum of 1024 stations per network with both 10BaseT and
10BaseF.
Q: When should I choose BaseT, BaseF (or others)?
A: The specific environment and application must be considered when selecting your media
type. However, there are some general rules-of-thumb that you can consider:
Avoid using copper between buildings. The electrical disturbances caused by lightning, as
well as naturally occurring differences in ground potential over distance, can very quickly
and easily cause considerable damage to equipment and people. The use of fiber-optic
cabling between buildings eliminates network cabling as a safety risk. There are also
various wireless media available for inter-building links, such as laser, spread-spectrum
RF and microwave.
10BaseT is the most flexible topology for LANs, and is generally the best choice for most
network installations. 10/100/1000BaseT hubs, or multi-hub concentrators, are typically
installed in a central location to the user community, and inexpensive UTP cabling is run
to each network device (which may be 100m, or 330ft, from the hub). The signaling
technology is very reliable, even in somewhat noisy environments, and 1 hubs will usually
detect many network error conditions and automatically shut-down the offending port(s)
without affecting the rest of the network (unless, of course, the offending port was your
server, shared printer, or router to the rest of the world.
100/1000BaseF, and its predecessor, FOIRL, are the only recommended topologies for
inter-building links. However, they need not be limited to this role. 100/1000BaseF can
also be run to the desktop, though the cost is prohibitively high in all but the most
specialized environments (generally, extremely noisy manufacturing facilities, or very
security-conscious installations). More commonly, FOIRL (and now, 10BaseF) is used
inside buildings and long distance wireless connections to form backbone networks.
Q: Is there an official "standard" punch down scheme for 10BaseT?

PAGE 5-6 SECTION 5: APPENDICES
A: Get a copy of EIA/TIA-568, it covers all of that sort of stuff: horizontal, vertical,
connectors, patch cords, cross-connects, etc.
Q: Is it safe to run Unshield Twisted Pair next to power cable?
A: According to EIA/TIA-569, the standard wiring practices for running data cabling and
companion to the above referenced EIA/TIA-568, you should not run data cable parallel to
power cables. However, in reality, this should not be a problem with networks such as
10BaseT. 10BaseT uses differential signaling to pick the data signals off the wire. Since
any interference from nearby power lines will usually affect all pairs equally, anything that
is not canceled-out by the twists in the UTP should be ignored by the receiving network
interface.
Q: Can I connect the 10BaseT interface of two devices directly together, without using a hub?
A: Yes, but not more than 2 devices, and you also need a special jumper cable between the
two 10BaseT ports:
RJ45 pin RJ45 pin
======== ========
1 <--[TX+]--------[RX+]--> 3
2 <--[TX-]--------[RX-]--> 6
3 <--[RX+]--------[TX+]--> 1
6 <--[RX-]--------[TX-]--> 2
Q: What is a "segment"?
A: A piece of network wire bounded by bridges, routers, repeaters or terminators.
Q: What is a "subnet"?
A: Another overloaded term. It can mean, depending on the usage, a segment, a set of
machines grouped together by a specific protocol feature (note that these machines do
not have to be on the same segment, but they could be) or a big nylon thing used to
capture enemy subs.
Q: What is a repeater?
A: A repeater acts on a purely electrical level to connect to segments. All it does is amplify
and reshape (and, depending on the type, possibly retime) the analog waveform to extend
network segment distances. It does not know anything about addresses or forwarding,
thus it cannot be used to reduce traffic as a bridge can in the example above.
Q: What is a "hub"?
A: A hub is a common wiring point for star-topology networks, and is a common synonym for
concentrator (though the latter generally has additional features or capabilities). 10BaseT
and 10BaseF Ethernet and many proprietary network topologies use hubs to connect
multiple cable runs in a star-wired network topology into a single network. Hubs have

Tsunami FAMILY
GIGABIT ETHERNET WIRELESS BRIDGES

SECTION 5: APPENDICES PAGE 5-7
multiple ports to attach the different cable runs. Some hubs (such as 10BaseT) include
electronics to regenerate and retime the signal between each hub port. Others (such as
10BaseF) simply act as signal splitters, similar to the multi-tap cable-TV splitters you
might use on your home antenna coax (of course, 10BaseF uses mirrors to split the
signals between cables).
Q: What is a bridge?
A: A bridge will connect to distinct segments and transmit traffic between them. This allows
you to extend the maximum size of the network while still not breaking the maximum wire
length, attached device count, or number of repeaters for a network segment.
Q: What does a "learning bridge"?
A: A learning bridge monitors MAC (OSI layer 2) addresses on both sides of its connection
and attempts to learn which addresses are on which side. It can then decide when it
receives a packet whether it should cross the bridge or stay local (some packets may not
need to cross the bridge because the source and destination addresses are both on one
side). If the bridge receives a packet that it doesn't know the addresses of, it will forward it
by default. IEEE’s standard for a learning bridge is 802.1D.
Q: Is there a maximum number of bridges allowed on a network?
A: Per IEEE 802.1 (d), the maximum number of concatenated brides in a bridged LAN is 7.
This number is rather arbitrary, however, and is based on simulations of application
performance with expected bridge delays.
In addition, the number assumes that all bridges are LOCAL (no remote WAN connections),
and that the default Hold Time of 1 second is in place (this is the time after which a bridge will
discard a frame it is holding). This prevents extra-late frame delivery. (i.e, a frame should
never be delivered more than ~7 seconds after is it sent). The rule of thumb for wireless WAN
bridged LANs is to limit the number of hops to 4.
Q: What is a router?
A: Routers work much like bridges, but they pay attention to the upper network layer
protocols (OSI layer 3) rather than data link layer (OSI layer 2) protocols. A router will
decide whether to forward a packet by looking at the protocol level addresses (for
instance, TCP/IP addresses) rather than the MAC address. Because routers work at layer
3 of the OSI stack, it is possible for them to transfer packets between different media
types (i.e., leased lines, Ethernet, token ring, X.25, Frame Relay and FDDI). Many routers
can also function as bridges.
Q: So should I use a router or a bridge?
A: There is no absolute answer to this. Your network layout, type and amount of hosts and
traffic, and other issues (both technical and non-technical) must be considered. Routing
would always be preferable to bridging except that routers are slower and usually more
expensive (due to the amount of processing required to look inside the physical packet

Tsunami FAMILY
GIGABIT ETHERNET WIRELESS BRIDGES
JANUARY 2001
PAGE 5-8 SECTION 5: APPENDICES
and determine which interface that packet needs to get sent out), and that many
applications use non-routable protocols.
Rules of thumb:
Bridges are usually good choices for small networks with few, if any, slow redundant links
between destinations or for connecting distant LANs. Further, bridges may be your only
choice for certain protocols, unless you have the means to encapsulate (tunnel) the un-
routable protocol inside a routable protocol.
Routers are usually much better choices for larger networks, particularly where you want
to have a relatively clean WAN backbone. Routers are better at protecting against
protocol errors (such as broadcast storms) and bandwidth utilization. Since routers look
deeper inside the data packet, they can also make forwarding decisions based on the
upper-layer protocols.
Occasionally, a combination of the two devices are the best way to go. Bridges can be
used to segment small networks that are geographically close to each other, between
each other and the router to the rest of the WAN.
Q: Are there problems mixing Bridging & Routing?
A: Only if you plan on having bridged links in parallel with routed links. You need to be very
careful about running bridges providing links in parallel to a router. Bridges may forward
broadcast requests which will confuse the router there are lots of protocols you may not
think of filtering (e.g. ARP, Apple ARP over 802.3 etc. etc.). Also, DECnet routers have
the same MAC address on all ports. This will probably cause the bridge to think it is
seeing an Ethernet loop.
Q: Who makes the fastest/easiest/most advanced bridges or routers?
A: The IETF runs bench marks on a wide selection of wired/fiber bridges and routers.
Network Computing runs bench marks for wireless routers (point-to-multipoint) and
bridges (point-to-point).
Q: What does "IPG" mean?
A: The InterPacket Gap (more properly referred to as the InterFrame Gap, or IFG) is an
enforced quiet time of 9.6 us between transmitted Ethernet frames.
Q: What means "promiscuous mode"?
A: Promiscuous mode is a condition where the network interface controller will pass all
Ethernet frames, regardless of destination address, up to the higher level network layers.
Normally the network controller will only pass up frames that have that device's
destination address. However, when put in promiscuous mode, all frames are passed on
up the network stack regardless of destination address. Promiscuous mode is usually
used by network monitoring tools and transparent bridges.
Q: What is a collision?
INSTALLATION AND MAINTENANCE MANUAL
Tsunami FAMILY
GIGABIT ETHERNET WIRELESS BRIDGES
JANUARY 2001
SECTION 5: APPENDICES PAGE 5-9
A: A condition where two devices detect that the network is idle and end up trying to send
packets at exactly the same time (within 1 round-trip delay). Since only one device can
transmit at a time, both devices must back off and attempt to retransmit again.
The retransmission algorithm requires each device to wait a random amount of time, so
the two are very likely to retry at different times, and thus the second one will sense that
the network is busy and wait until the packet is finished. If the two devices retry at the
same time (or almost the same time) they will collide again, and the process repeats until
either the packet finally makes it onto the network without collisions, or 16 consecutive
collision occur and the packet is aborted.
Q: What causes a collision?
A: See above. Ethernet is a CSMA/CD (Carrier Sense Multiple Access/ Collision Detect)
system. It is possible to not sense carrier from a previous device and attempt to transmit
anyway, or to have two devices attempt to transmit at the same time; in either case a
collision results. Ethernet is particularly susceptible to performance loss from such
problems when people ignore the "rules" for wiring Ethernet.
Q: How many collisions are too many?
A: This depends on your application and protocol. In many cases, collision rates of 50% will
not cause a large decrease in perceived throughput. If your network is slowing down and
you notice the percentage of collisions is on the high side, you may want try segmenting
your network with either a bridge or router to see if performance improves.
Q: How do I reduce the number of collisions?
A: Disconnect devices from the network. Seriously, you need to cut- down on the number of
devices on the network segment to affect the collision rate. This is usually accomplished
by splitting the segment into two pieces and putting a bridge or router in between them.
Q: What is a late collision?
A: A late collision occurs when two devices transmit at the same time, but due to cabling
errors (most commonly, excessive network segment length or repeaters between
devices) neither detects a collision. The reason this happens is because the time to
propagate the signal from one end of the network to another is longer than the time to put
the entire packet on the network, so the two devices that cause the late collision never
see that the other's sending until after it puts the entire packet on the network. Late
collisions are detected by the transmitter after the first "slot time" of 64 byte times. They
are only detected during transmissions of packets longer than 64 bytes. It's detection is
exactly the same as for a normal collision; it just happens "too late."
Typical causes of late collisions are segment cable lengths in excess of the maximum
permitted for the cable type, faulty connectors or improper cabling, excessive numbers of
repeaters between network devices, and defective Ethernet transceivers or controllers.
Another negative concerning late collisions is that they occur for small packets also, but
cannot be detected by the transmitter. A network suffering a measurable rate of late
collisions (on large packets) is also suffering lost small packets. The higher protocols do
not cope well with such losses. Well, they cope, but at much reduced speed. A 1% packet

PAGE 5-10 SECTION 5: APPENDICES
loss is enough to reduce the speed of NFS by 90% with the default retransmission timers.
That's a 10 times increase of the problem!
Finally, Ethernet controllers do not retransmit packets lost to late collisions.
Q: What is a jam?
A: When a workstation receives a collision, and it is transmitting, it puts out a jam so all other
stations will see the collision also. When a repeater detects a collision on one port, it puts
out a jam on all other ports, causing a collision to occur on those lines that are
transmitting, and causing any non-transmitting stations to wait to transmit.
Q: What is a broadcast storm?
A: An overloaded term that describes an overloaded protocol. Basically it describes a
condition where devices on the network are generating traffic that by its nature causes the
generation of even more traffic. The inevitable result is a huge degradation of
performance or complete loss of the network as the devices continue to generate more
and more traffic. This can be related to the physical transmission or to very high level
protocols.
Q: How do I recognize a broadcast storm?
A: That depends on what level it is occurring. Basically you have to be aware of the potential
for it beforehand and be looking for it, because in a true broadcast storm you will probably
be unable to access the network. This can change dramatically for a higher level protocol.
NFS contention can result in a dramatic DROP in Ethernet traffic, yet no one will have
access to resources.
Q: How can I prevent a broadcast storm?
A: Avoid protocols that are prone to it. Route (with routers) or Bridge (with wired/wireless
bridges) when it is practical.
Q: What is *high* traffic on an Ethernet? 5%? 20%? 90%?
A: High traffic is when things start slowing down to the point they are no longer acceptable.
There is not set percentage point, in other words. Usually start paying attention when it
gets over 40-50%.
Q: Why do I see different throughput speeds?
A: Bridges (such as Tsunami) are ISO Layer 2 Data Link Layer (use MAC address for
filtering) devices where they provide their full stated throughput. At level 2 (bridges) or 3
(routers) where hardware plays the major part, the most common tester is the SmartBits
200 product from NetCom Systems. At Application Layer 7, you will see less than 40%
throughput from the maximum capacity measured w/SmartBits due to the increased
protocol/software overhead at that level. Layer 7 can be tested with software such as
Ganymede's Chariot or Qcheck product.

As an example: testing copper CAT5 cable with SmartBits will test 100% throughput (let's
say you can send/rcv a full 10Mbps). At Layer 7 you will be transferring data at the
10Mbps rate, but only 4Mbps of user data will transfer (Ethernet has a high overhead of
bytes added to each data packet each time you go up a layer). The advantage is the more
complex overhead makes the data virtually resilient to corruption and minor errors (i.e.
collisions), it’s easy to reroute and can use inexpensive plug/play devices like
hubs/switches instead of multiplexers as used in the telco industry (i.e. LYNX T1 radios)
Western Multiplex tests at Layer 2 where bridges are defined. At layer 7 (Application
Layer), you will see less than 40% or more depending on the other traffic that may be on
the LAN as this layer is more dependent on the type of data being sent (it does not matter
if it's wire, fiber or any Ethernet bridge -wired or wireless). Another way to look at it: the
model 31145 12Mbps (10Mbps 10BaseT+T1/E1 wayside) bridge will test the same as a
piece of CAT5 Ethernet cable.
Q: How can I test an Ethernet?
A: This depends on what level you want to test. The most basic test (a.k.a., "the fire test") is
to connect a pair of devices to the network and see if they can communicate with each
other. If you want to test the electrical integrity of the wire (i.e., will it carry a signal
properly), a TDR or cable scanner that incorporates TDR and other functions, would be
the most comprehensive tool. If you need to test the performance or troubleshoot protocol
transmission problems, you will need special and usually very expensive software, usually
coupled with custom hardware, to capture, optionally filter, and analyze the network
packets. Also, see the answer to the question above.
Q: What is a "TDR"?
A: A Time-Domain Reflectometer is a tool used to detect cable faults. This device operates
by sending a brief signal pulse down the cable and looking for its reflection to bounce
back. By analyzing the reflected pulse, it is possible to make judgments about the quality
of the cable segment. More advanced units can not only detect and identify the nature of
the problem, but give a reasonably accurate indication of the problem's location (distance
from the point of the test). There is also a device known as an OTDR, which is an Optical
Time-Domain Reflectometer for fiber-optic cables.
Q: What is a "BERT"?
A: Bit Error Rate Tester. This equipment is used to analyze the amount and types of errors
that occur on a cable segment.
Q: What (free) tools are there to monitor/decode/etc an Ethernet?
A: There are many built into most DOS ,Unix and other operating systems. For example, the
ping command can be used to determine if a given host is alive, and will also tell you the
round trip transmission time. The command “ifconfig” will tell you the status of the network
interfaces. “netstat” will summarize statistics for network usage.
DOS commands (through Windows DOS application) are:

Displays and modifies the IP-to-Physical address translation tables used by address
resolution protocol (ARP).
ARP -a [inet_addr] [-N if_addr]
-a Displays current ARP entries by interrogating the current protocol data. If
inet_addr is specified, the IP and Physical addresses for only the specified
computer are displayed. If more than one network interface uses ARP, entries for
each ARP table are displayed.
-g Same as -a.
inet_addr Specifies an internet address.
-N if_addr Displays the ARP entries for the network interface specified by if_addr.
-d Deletes the host specified by inet_addr.
-s Adds the host and associates the Internet address inet_addr with the Physical
address eth_addr. The Physical address is given as 6 hexadecimal bytes
separated by hyphens. The entry is permanent.
eth_addr Specifies a physical address.
if_addr If present, this specifies the Internet address of the interface whose
address translation table should be modified. If not present, the first
applicable interface will be used.
Example:
> arp -s 157.55.85.212 00-aa-00-62-c6-09 .... Adds a static entry.
> arp -a .... Displays the arp table.
FTP
Transfers files to and from a computer running an FTP server service (sometimes called
a daemon). FTP can be used interactively.
FTP [-v] [-d] [-i] [-n] [-g] [-s:filename] [-a] [-w:windowsize] [-A] [host]
-v Suppresses display of remote server responses.
-n Suppresses auto-login upon initial connection.
-i Turns off interactive prompting during multiple file transfers.
-d Enables debugging.
-g Disables filename globbing (see GLOB command).
-s:filename Specifies a text file containing FTP commands; the commands will
automatically run after FTP starts.
-a Use any local interface when binding data connection.
-A login as anonymous.
-w:buffersize Overrides the default transfer buffer size of 4096.
host Specifies the host name or IP address of the remote host to connect to.
Notes:
- mget and mput commands take y/n/q for yes/no/quit.
- Use Control-C to abort commands.
NET CONFIG Displays your current workgroup settings.
NET DIAG Runs the Microsoft Network Diagnostics program to display

PAGE 5-14 SECTION 5: APPENDICES
Manipulates network routing tables.
ROUTE [-f] [command [destination] [MASK netmask] [gateway] [METRIC metric]]
-f Clears the routing tables of all gateway entries. If this is used in conjunction with
one of the commands, the tables are cleared prior to running the command.
command Must be one of four:
PRINT Prints a route
ADD Adds a route
DELETE Deletes a route
CHANGE Modifies an existing route
destination Specifies the destination host.
MASK Specifies that the next parameter is the 'netmask' value.
netmask Specifies a subnet mask value to be associated with this route entry. If
not specified, it defaults to 255.255.255.255.
gateway Specifies gateway.
METRIC Specifies that the next paramenter 'metric' is the cost for this destination
All symbolic names used for destination are looked up in the network database file
NETWORKS. The symbolic names for gateway are looked up in the host name database
file HOSTS.
If the command is PRINT or DELETE, wildcards may be used for the destination and
gateway, or the gateway argument may be omitted.
Diagnostic Notes:
Invalid MASK generates an error, that is when (DEST & MASK) != DEST.
Example> route ADD 157.0.0.0 MASK 155.0.0.0 157.55.80.1
The route addition failed: 87
Examples:
> route PRINT
> route ADD 157.0.0.0 MASK 255.0.0.0 157.55.80.1 METRIC 3
