2 System Overview
A system is made up of one to six Base Stations that make up a Hub (or cell) with each Base Station
communicating with their associated SUs (Subscriber Units). Together, they provide a wide coverage,
high-capacity system that transfers IP traffic between the Hub and its multiple SUs. Each Hub has the
ability to communicate in all directions using up to six sectors of 60 degrees each. Each of the Hub’s six
sectors has the capability of communicating 20 Mbps in total bandwidth allowing a maximum of 360
Mbps per Hub.
Figure 2-1: Each HUB is made up of one to six Base Stations and
multiple remotes(SUs)
Uplink and Downlink, each SU communicates with a BSU in a coordinated manner so that
all other remotes within the BSU’s jurisdiction have an equal amount of time to coordinate
their data needs in both the uplink and downlink sessions. All SUs are very quickly handled on
a case by case basis giving the user, at the SU, the impression that they are in constant
communication with its Hub’s or BSU’s Sector.

Point-to-Multipoint Network Model
When we talk about the PMP network, one should look at the Subscriber Unit (SU)
and the Base Station Unit (BSU) as an integrated transmission and switching medium
with physical ports or access points that interface to end user devices. Each Base
Station Unit or SU represents one such physical port or access point. Packets received
by a SU are transmitted to the Base Station Unit and emerge out from it as a single
data stream. Packets flowing into the Base Station Unit are broadcasted to the SUs,
which select only packets destined for their local networks based on a set of filtering
criteria.

Depending on the transmission mode selected, the PMP network can function either
as a "bridge" or as an "IP gateway" to the end user. In Bridging mode, the PMP
network provides a direct physical connection between a SU and its Base Station Unit
for the exchange of Ethernet frames between the two entities. To conserve wireless
bandwidth, the SU uses some simple filtering criteria in hardware and software to
prevent traffic destined for local network to be sent uplink. If the destination Ethernet
address is not in the hardware table, the packet is given to software, which provides
further filtering by matching the destination address with local addresses stored in its
ARP table. The size of the ARP table is set to 512.
In the downlink direction, the outbound traffic is filtered in the SU via a
"Programmable Hash Filter". If the destination Ethernet address of a downlink packet
2-1

triggers a "hit" in the hash list, the hardware will forward the packet to software for
delivery to the local network. Otherwise, the packet is discarded.

Limitations of the Bridging Mode
Again, if we consider the PMP network as a multi-port bridge, then it exhibits only a
limited bridging function. For a true bridge to work, whatever traffic flows into one
port should be fanned out to all the other ports, if the destination Ethernet address is
not local to the receiving port. For the PMP network to behave the same, whatever
data received by the Base Station Unit from a SU should also be broadcasted back
downlink to all other SUs associated with the Base Station Unit. However, this is not
done.

Other than the above constraint, Bridging mode also consumes more wireless
bandwidth than IP Routing mode for several reasons. First, the entire Ethernet frame,
which includes the 18 bytes Ethernet header, is transmitted between the SU and the
Base Station Unit. Second, all ARP packets are transmitted between the SU and Base
Station Unit as well. Empirical result has shown that in general Bridging mode can
consume up to 10% more bandwidth than IP Routing mode.
VLAN Switching – The PMP Implementation
VLAN switching is mainly used for segregating LAN traffic based on VLAN ID that
accompanies a received VLAN frame. It allows a network operator to partition his
LAN segment into closed user groups and allow a device to communicate only with
other devices of the same group. Unlike a regular bridge, a VLAN switch is able to
deliver received VLAN frames only to other ports tagged with the same VLAN ID,
thus reducing unwanted network traffic.
VLAN switching is quick and simple from a switching node’s perspective. However,
setting up a VLAN network can be a mundane exercise for the network administrator.
The reason is that most of the end user devices today (PCs for example) are not
VLAN aware. This forces the network operator to place VLAN switches at critical
junctions all over the place so that VLAN frames can be converted into regular
Ethernet frames and vice versa. This can be a nightmare and a costly endeavor if
proper planning does not take place beforehand. There is a built-in VLAN to
Ethernet conversion capability in the SUs and Base Station Units, as illustrated in
Figure 2-5.

T S U N A M I
M U L T I P O I N T
In Fig.2-5 above, the VLAN switch has both tagged and untagged ports. A tagged
port can only receive and transmit VLAN frames. For a port such as port 1 that
associates with multiple VLAN ids, it has to be tagged. An untagged port can receive
both tagged VLAN frames or untagged regular Ethernet frames but will only transmit
untagged Ethernet frames. An untagged port can only be associated with one unique
VLAN id and is most commonly used for connection to VLAN unaware devices. As
shown in Fig. 2.2, SU1, PC1, SU3, PC3 and router2 form a closed user group
associated with VLAN id 2. SU 2, PC2 and Router1 form another closed user group
associated with VLAN id 3. When SU1, for example, receives a regular Ethernet
frame from PC1, it tagged the frame with VLAN id 2, which is SU1’s configured
VLAN id. The VLAN frame is passed to the VLAN switch via BS1 and broadcasted
to port 2 and port 4 of the VLAN switch. When SU3 receives the VLAN frame from
BS2, it converts the VLAN into regular Ethernet frame and gives it to PC3.
For control purpose, the VLAN IDs of all Base Station Units are hard coded to 1 and
cannot be changed by the operator. For any device such as Wireless Manager or
Ethernet Console to communicate with a Base Station Unit, the device needs to be
connected to an untagged VLAN port associated with VLAN ID 1. Otherwise, the
Base Station Unit will not be reachable. When a Base Station Unit wants to transmit a
control message or send a response back to the Wireless Manager or Ethernet
Console, it will transmit a tagged VLAN frame of id 1, which will be received by all
devices connected to VLAN ports associated with VLAN id 1.
In PMP network VLAN switching is a special Bridging mode with the VLAN tag
enabled in the Base Station Unit configuration. As such, VLAN switching is also
bounded by the same constraint that SUs within the same Base Station Unit cannot
communicate with each other. VLAN switching is not supported in IP routing mode.
IP Routing and Default Gateway
In IP routing mode, a SU performs the following functions. First, it serves as a DHCP
relay agent that facilitates the exchange of DHCP packets between the local PC and a
remote DHCP server and also automatically becomes the PC's default IP gateway at
the end of the process once the PC obtains its IP address assignment. Second, the SU
provides additional network security measures by blocking any unauthorized PCs
from accessing the wireless network. Four access modes have been implemented, as
described below:
A: RESTRICTED ACCESS
In this mode, for any device with an IP address not obtained from DHCP to access
the PMP network, its static IP address must first be recorded in the PMP's database.
We allow up to 5 static IP addresses to be associated with each SU.
In the Restricted mode, the Programmable Hash Filter discussed earlier contains only
the DHCP based IP addresses, the static IP addresses and the gateway address that
2-5
T S U N A M I
M U L T I P O I N T
have been registered. Any device with an IP address not in the PMP's configuration
database will not be able to access the wireless network.
B. LOCAL ACCESS
In this mode, any device connected directly to the SU's local network will be able to
access the network, regardless of how its IP address is obtained.
C. OPEN ACCESS
This mode allows any device connected either directly to the SU's local network or
indirectly via a router to access the wireless network. When this mode is activated, the
Programmable Hash Filter is disabled, allowing the SU software to receive all
downlink packets. If the downlink packet is destined for the SU’s local network, the
software will deliver the packet directly. If the downlink packet belongs to a different
subnet or network, the software will forward the packet to its gateway, which serves as
the SU's default gateway to external networks.
D. SUBNET ACCESS
This mode is same as the Local Access Mode except that the Programmable Hash
Filter is opened wide enough just to include all IP addresses that reside within the SU's
own subnet.
Address Filters in IP Routing Mode
In IP Routing mode, the uplink filtering is done via the access control mechanisms as
described earlier. For downlink direction, IP addresses instead of Ethernet addresses
are used in the hash filter. If a hash hit is triggered, the software will search its ARP
table to locate the destination Ethernet address that corresponds to the destination IP
address contained in the packet. If an entry is not found the packet will be discarded.

Proxy: to ARP or not to ARP ....
In addition to enforcement of the access modes discussed above, one of the main
functions of the SU is to serve as a proxy server for the local devices. Without this
function many of our network applications will fail. Before we go into detailed
discussions, however, we need to first understand the basics in IP networking.
When a device such as a PC, router, SU or Base Station Unit wants to transmit an IP
packet, it needs to first decide if the destination IP address resides within its own
subnet. If the answer is yes, the sending device needs to search for the corresponding
Ethernet address associated with the destination IP address by broadcasting an ARP
request to its local network. A device with a matching IP address or one which is
interested in receiving packets for that IP address will send back an ARP response,
which contains the destination Ethernet address. Once the destination Ethernet
address is known, the sending device can then deliver the packet directly to that
Ethernet address. If the destination IP address resides in a different subnet, then the
sending device will not even bother to issue an ARP request but will instead forward
the packet to a default gateway for delivery.
Now back to the PMP discussion. In the PMP network, it is quite common to have
multiple SUs share the same subnet address. In that case, when a PC connected to a
SU wants to send packets to a PC connected to another SU, the originating PC will
issue an ARP request to explore the Ethernet address of the destination PC, since
both of them reside in the same subnet. Unfortunately, the destination PC will not be
able to receive the ARP request because it is not physically connected to the
originating PC. This then forces the SU connected to the originating PC to issue a
proxy response on behalf of the destination PC. The SU will issue a proxy response
only when it knows via initial learning that the destination PC is not connected to its
local network.

T S U N A M I

The proxy capability allows SUs in the PMP network to share the same subnet
address, even though they are not directly connected. Without this capability, all the
SUs in the network will be forced to have different subnet addresses.

Network Configurations in the IP Routing Mode
In the PMP network, IP routing mode is superior to Bridging mode for several
reasons. First, as mentioned earlier, IP Routing mode conserves wireless bandwidth.
Second, it provides added control over which hosts attach to the network. Third, it
allows communications among end user devices associated with the same Base Station
Unit. Fourth, it gives the network operator greater freedom in partitioning his network
into logical subnets. However, if the operator expects his network to run smoothly in
IP Routing mode, some careful forward planning will be required, as illustrated in the
following examples.

In this configuration two subnets 191.168.20.0 and 191.168.21.0 are installed. BS1
belongs to subnet 191.168.20.0 and is connected to one of the router ports, which has
the same subnet address. BS2 belongs to subnet 192.168.21.0 and is connected to a
second router port with the same subnet address.
For PC1 to send a packet to PC2, it will first issue an ARP request, which SU1 will
respond on behalf of PC2 as part of the proxy process described earlier.
PC1 then transmits data packets to SU1, which forwards only the IP portion to BS1
after stripping off the 18 bytes Ethernet header. BS1 delivers the packet to Router1
after appending its own Ethernet address as the source Ethernet address. Router1
recognizes that the destination address belongs to subnet 192,168,20,0 and forwards it
back to BS1 via the same router port. The packet is received by SU2 via BS1 and
filtered via the Programmable Hash Filter since PC2's address is already recorded in
SU2’s database. The packet is delivered to software, which searches via its ARP table,
appends PC2's Ethernet address as the destination Ethernet address and its own
address as the source Ethernet address and delivers the packet to PC2.
For PC1 to send a packet to PC3, it will forward the packet to SU1 since the
destination address lies outside of PC1's subnet and also that SU1 is PC1's default
gateway. When Router1 receives the packet it recognizes that the destination address
belongs to a different subnet than that of the receiving port. The packet is then sent to
BS2 via the other router port and is ultimately received by PC3 following similar
process described above. PC4 cannot access the network because its IP address is not
recognized by the SU in Restricted mode.

For illustrative purpose, all SUs and Base Station Units are assigned to different
networks. This is possible because in IP Routing mode the PMP network can function
like a multi-port router where each port has its own network address. In this
configuration we have added Router2, which is connected to SU4 and also to PCX via
a second port with a different network interface 175.168.20.0. In order for SU4 to
receive IP packets for PCX or any unknown device that is connected to Router2, its
hash mode must be set to OPEN. For PCX to send data to PC2, it will deliver the
packet to Router2, which is PCX's gateway to the PMP network. Router2 forwards
the packet to SU4, which is its default gateway. SU4 delivers the packet to Router1 via
BS2. Router1 forwards the packet to BS1. The packet is received by SU2 and delivered
to PC2. If PC2 wants to send packet to PCX, it will forward the packet to SU2, which
delivers the packet to Router1 via BS1. Router1 then sends the packet to SU4 via BS2.
Since hash mode for SU4 is set to OPEN, the hardware will deliver the packet to
software bypassing the Programmable Hash Table. SU4 recognizes that this packet is
for a different subnet and forwards it to Router2 for delivery to PCX.
USEFUL HINTS FOR TESTING PMP NETWORK UNDER BRIDGING MODE
Before changing the Base Station Unit Configuration to VLAN switching, make sure
that the Base Station Unit and the Ethernet console are connected to a VLAN switch.
Otherwise, you will not be able to talk to the Base Station Unit again since the PC
hosting the Ethernet Console cannot send or receive VLAN frames.
USEFUL HINTS FOR TESTING PMP NETWORK UNDER IP ROUTING MODE
Make sure to configure the Base Station Unit to have the router port as its default
gateway and that the IP addresses of the Base Station Unit and the router port reside
in the same subnet. Also remember to configure the router port to point to the Base
Station Unit as its gateway.
Make sure that a SU and its directly connected devices are in the same subnet. The
subnet address of a device can be obtained by logically “AND” the device’s IP address
with its subnet mask. A subnet mask of 255.255.255.0 implies that there are 255 IP
addresses within the same subnet.
If the IP address of a PC connected to a SU is not dynamically assigned, make sure
that the PC’s IP address appears in the SU’s static IP list. Otherwise, the PC will not
be able to access the wireless network if the SU is running in Restricted mode. Also,
remember to configure the PC to point to the SU as its default gateway.
In the latest firmware release, the proxy setting is turned on automatically – don’t
change the setting.

USEFUL HINTS FOR ANYONE TRYING TO OPERATE THE PMP NETWORK
When changing back and forth between Bridging mode and IP routing mode, always
remember to manually clear the ARP table of your PC.
Don’t just turn off the power of the Base Station Unit “at-will” because the Base
Station Unit might be saving internal variables or configuration parameters to the flash
memory at that moment. Always wait for a minute after keying in an operator
command before shutting the Base Station Unit down.
It is wise to connect a Wireless Manager (WM) to the PMP network. The WM serves
as an external data storage and configuration backup for the PMP network, even if we
don’t care about its other features. The configuration is downloaded from WM to a
Base Station Unit every time the Base Station Unit is powered up.
Always follow the simple proxy rule and fundamental principles concerning subnet
and default gateway in planning and analyzing the PMP network. A good
understanding of the basic IP Networking is needed regardless of whether you operate
the PMP network in IP Routing or Bridging mode.
If you cannot get the network to work - most likely there is a set up error. Check the
network configuration using the above hints and try again.

3 Site Planning & Installation
The installation of a wireless network requires much the same basic planning as any
wired network. The main difference is that the wireless signal requires some additional
planning. This planning includes RF path planning, site preparation, and installation of
outdoor components such as outdoor units, antennas, lightning protection devices,
and cabling suitable for outdoor conditions.
Although the technology implemented in this broadband fixed wireless system can
make use of multipath signals, reducing the effect of obstructions in the path, it is
important that the characteristics of the path be carefully examined. With this
knowledge, components and network requirements can be correctly planned for your
specific application.
This chapter provides insight into the planning necessary to prepare your site for your
broadband fixed wireless system.
General Considerations
A basic consideration is the physical location of the sites at each end of the link.
Because microwave signals travel in a straight line, a clear line of sight between
antennas is ideal. Frequently, however, the locations of the desired links are fixed.
When a clear line of sight cannot be achieved, you must plan accordingly.
Other general site considerations include:
a. Will a tower have to be constructed? Are permits required?
b. Possibility of future obstructions-Will trees grow high enough to interfere
with the signal? Are there plans to erect buildings between the sites that may
obstruct the path?
c. Availability of grounding-Good grounding is important in all areas of the
world, but in areas prone to lightning, it is especially critical.
d. Distance between the indoor portion of the system and the user’s network.
e. The SU may potentially be served by different Base Stations. Can the best
BSU access and available sighting location be determined prior to installation.
3-1
T S U N A M I
M U L T I P O I N T
The planning of a wireless link involves collecting information and making decisions.
The following sections will help you determine which information is critical to the site
and will be an aid in the decision-making process.
Weather
It is important to research any unusual weather conditions that are common to the site
location. These conditions can include excessive amounts of rain, wind velocity or
extreme temperature ranges. If extreme conditions exist that may affect the integrity of
the radio link, it is recommended that these conditions be taken into consideration
early in the planning process.
RAIN
Except in extreme conditions, attenuation (weakening of the signal) due to rain does
not require serious consideration for frequencies up to the range of 6 GHz. When
microwave frequencies are at 10-12 GHz range or above, attenuation due to rain
becomes much more of a concern, especially in areas where rainfall is of high density
and long duration. The systems discussed in this manual operate at frequencies below
6 GHz, so rain is not a concern.
Temperature can adversely affect the radio link when such as temperature inversion,
or very still air accompanied by stratification. Temperature inversion can negate
clearances, and still air along with stratification can cause severe refractive or reflective
conditions, with unpredictable results. Temperature inversions and stratification can
also cause ducting, which may increase the potential for interference between systems
that do not normally interfere with each other. Where these conditions exist, it is
recommended that shorter paths and adequate clearances are used.
WIND
Any system components mounted outdoors will be subject to the effect of wind. It is
important to know the direction and velocity of the wind common to the site.
Antennas and their supporting structures must be able to prevent these forces from
affecting the antenna or causing damage to the building or tower on which the
components are mounted. Antenna designs react differently to wind forces, depending
on the area presented to the wind. This is known as wind loading.
Note For definitions of wind loading specifications for antennas and towers, refer
to TIA/EIA- 195 (for antennas) or TIA/EIA-222 (for towers) specifications.
LIGHTNING
The potential for lightning damage to radio equipment should always be considered
when planning a wireless link. A variety of lightning protection and grounding devices
3-2
T S U N A M I
M U L T I P O I N T
are available for use on buildings, towers, antennas, cables, and equipment, whether
located inside or outside the site, that could be damaged by a lightning strike.
Lightning protection requirements are based on the exposure at the site, the cost of
link down-time, and local building and electrical codes. If the link is critical, and the
site is in an active lightning area, attention to thorough lightning protection and
grounding is critical.
LIGHTNING PROTECTION
To provide effective lightning protection, install antennas in locations that are unlikely
to receive direct lightning strikes, or install lightning rods to protect antennas from
direct strikes. Make sure that cables and equipment are properly grounded to provide
low-impedance paths for lightning currents. Install surge suppressors on adjacent
telephone lines and power lines.
Recommended is additional lightning protection in those regions that have extreme
lightning occurrences for cables leading to the wireless OutDoor Unit (ODU)
to/from the indoor power brick. This optional lightning protection should be placed
at points close to where the cable passes through the bulkhead into the building, as
well as near the ODU. Use the earthing screw at the ODU and use proper grounding.
CAT5 CABLE
When the entire control cable, from the building entrance to the ODU, is encased in
steel conduit, no surge arrestors are required. Otherwise, each control cable requires
one surge arrestor within two feet of the building entrance.
Note For installations with several radios, it may be more convenient to use a Type66 punch block with surge arrestors. A Type-66 punch block can accommodate up to
25 conductor pairs.
Interference
An important part of planning your broadband fixed wireless system is the avoidance
of interference. Interference can be caused by effects within the system or outside the
system. Good planning for frequencies and antennas can overcome most interference
challenges.
CO-CHANNEL AND ADJACENT CHANNEL INTERFERENCE
Co-channel interference results when another RF link is using the same channel
frequency. Adjacent-channel interference results when another RF link is using an
adjacent channel frequency. In selecting a site, a spectrum analyzer can be used to
determine if any strong signals are present at the site and, if they are, to determine how
3-3
T S U N A M I
M U L T I P O I N T
close they are to the desired frequency. The further away from your proposed
frequency, the less likely they are to cause a problem.
Antennas
Antennas frequently play a key role in reducing the potential for interference. They
come in a variety of configurations that have different performance characteristics in
the areas of gain and directionality. Antennas that transmit/receive in all directions are
known as omni-directional, while those that transmit/receive in one specific direction
are categorized as directional. Antennas also vary in beamwidth, which is the aperture
to which they can “see” signals. Larger antennas typically provide narrower
beamwidths and can diminish interference from nearby transmitters by:
• Focusing RF energy from the intended destination
• Reducing the power of interfering sources not directly aligned to the antenna
Antennas: the narrower, the better
Tsunami Multipoint Ethernet Systems use integrated directional antennas that
transmit and receive a relatively narrow beamwidth of radio energy, improving system
performance by reducing the likelihood that surrounding RF clutter will interfere with
reception. The antennas with this system are directional and can not be detached.

Even when other licensees are not an issue, if you are using a network deployment
using the "cell" approach, all these considerations are still important to reduce
interference between your own adjacent installations. Antennas are tuned to operate
on a specific group of frequencies. Tsunami Multipoint offers a variety of channel
plans that provide a flexible tool for overcoming present and future interference. Four
non-overlapping 20 MHz channels (six total directional channels) can be used to avoid
existing traffic in the 5.8 GHz frequency band. If one part of the 5.8 GHz spectrum is
occupied when Tsunami Multipoint is initially deployed, another frequency channel
can be selected to bypass the interfering signal. If interference arises after deployment,
another frequency channel plan can be selected to “steer around” the impacted
channel. Beamwidth and gain have been optimized in this equipment.
ANTENNA POLARIZATION
The Tsunami Multipoint system uses left-hand circular polarization. As a result, the
signal is successfully received regardless of the orientation of the antenna. Circular

T S U N A M I
M U L T I P O I N T
polarization also provides protection against multipath degradation of the signal
quality.
TOWERS
When planning antenna placement, it might be necessary to build a free-standing
tower for the antenna. Regulations and limitations define the height and location of
these towers with respect to airports, runways, and airplane approach paths. These
regulations are controlled by the FAA. In some circumstances, the tower installations
must be approved by the FAA, registered with the FCC, or both.
To ensure compliance, review the current FCC regulations regarding antenna
structures. These regulations (along with examples) are on the FCC web site at
wwwfcc.gov/wtb/antenna/.
Path Planning
To get the most value from a wireless system, path planning is essential. In addition to
the fact that radio signals dissipate as they travel, many other factors operate on a
microwave signal as it moves through space. All of these must be taken into account,
because any obstructions in the path will attenuate the signal.
CALCULATING A LINK BUDGET
A link budget is a rough calculation of all known elements of the link to determine if
the signal will have the proper strength when it reaches the other end of the link. To
make this calculation, the following information should be considered.
A signal degrades as it moves through space. The longer the path, the more loss it
experiences. This free-space path loss is a factor in calculating the link viability. Freespace path loss is easily calculated for miles or kilometers.
Availability represents the quality of a link. It is the ratio of the time that the link is
available to the total time. This serves as a guide to the service that you can expect, on
average, over a period of one year. Table 2-2 shows how percentage availability relates
to outage time per year.
Note: use the path planning tools located on the WMUX web site: www.wmux.com
Note You can lower the bit error rate (BER), resulting in greater reliability, by
reducing the data throughput or reducing the distance.
UNLICENSED FREQUENCIES-ISM
The FCC has identified the frequencies from 5.725 to 5.825 GHz as an Industrial,
Scientific, Medical (ISM) band. This band can be used by anyone without having to
3-5
T S U N A M I

obtain a license. However, you must use radio equipment that is "type approved" by
the FCC or local government for use within the specific band.

Crimping Method for Connector Termination
Loose piece contacts are designed to be crimped with crimp tooling (hand tools, die
assemblies, or crimping heads), but can be done with normal hand tools. The
applicable crimp tooling for the contacts is described later. Read the material packaged
with the crimp tooling for the proper crimping procedure.

Figure 3-2: Crimping styles and insertion
Insertion - Normally, an insertion tool is not required to insert contacts into the housings.
However, if the wire bundle is large, or if the wire is fragile, an insertion tool is recommended.
To insert a contact, grip insulation of wire (directly behind contact) and align contact with
BACK of desired contact cavity. Insert contact straight into cavity until it bottoms. Pull back
lightly on wire to be sure contact is locked in place.
Extraction - Extraction tools are designed for removing pin and socket contacts from the
connectors. Refer to the instruction material packaged with the tool for the proper extraction
procedure.
MATING CONNECTORS
These connectors have a positive lock feature which prevents accidental disengagement. Align
polarizing keys and keyways and start plug into receptacle. Rotate coupling ring CLOCKWISE
until positive lock snaps into position.
Do not use for blind mating applications.

Wire Size and Preparation
Contacts are available for the wire sizes specified. Prepare wire for crimping by stripping insulation. DO
NOT nick, scrape, or cut the stranded or solid wire conductor during stripping operation.
When using twisted pair cable, one wire should be cut shorter than the other by the same distance as the strip length of the
longer wire.
WirePreparation
Loading Contact Into Housing
Normally an insertion tool is not required to insert contacts Into housings. However, if the wire bundle is large or the individual wires
are fragile, the use of an Insertion tool is recommended.
Shield and Strain Relief
If wire at the rear of the housing is subjected to strain, use of a strain relief will prevent damage to the contacts, wires,
and housing.
Strain Relief Kits
Several types and sizes of strain relief kits are available. Shield and strain relief kits include a shield, strain relief
clamps, and two self-tapping screws. Flexible strain relief boots and grippers are used with jacketed cable (or firmly
taped discreet wires) to provide wire protection and prevent contact pullout when severe cable angle applications are
encountered, or when connectors are frequently disconnected and reconnected. Heat shrink sealing boots can also
provide a splash-proof strain relief for jacketed cable.
NOTE
If a strain relief Is used on the connector, the wires may be dressed to an angle at the and of the strain relief.
However, without use of a strain relief, the wires. should not be dressed closer then 2.50 inches from the back of
the housing. To prevent damage to contacts and/or housing, avoid exerting stress on wire.

Alternative Method of Connection
Another method that is acceptable is to use what are called “jelly beans” or Telephone
Wire Tap Connectors. These moisture resistant and easy to install devices have been
used by the telephone industry for years both indoors and out (for this installation,
recommendation is for using only indoors). These can be purchased at many
electronic supply stores worldwide including Radio Shack (part #64-3081), Tandy or
through most well stocked DYI stores. For this method, you will need eight (8) of
these devices per cable.
Self-stripping tap connectors permit a
continuous feed or loop without interruptions
and let you splice wires without cutting any
conductors. The connectors can be used with
Where you had to cut the cable for entry or egress, strip back the outer CAT5 cable
jacket about two (2) inches on each side of the cut – do not strip the individual wires
leaving bare copper! Into each 2-wire Tap Connector, push in the like colored wires
from each cable end firmly and equally into the Tap. While holding the wires in firmly,
squeeze the button with wide pliers to equally force the button into the Tap. If
properly done, the button will now be flush with the rest of the Tap Connector body
and the two wires will not pull out. Continue with the installation of seven (7) more of

these Taps being sure that each wire from the ends of each severed cables match
exactly in color per each Telephone-type Wire Tap Connector.
Refer to the table below that provides the details on each of the eight (8) wires that will
need to be spliced from one cable to the like color on the other cable. After
successfully installing the wire tap devices, the severed cable will carry the Ethernet
and voltages necessary for operation.

Mechanical Considerations – Mounting Units
The outside component of your Tsunami Multipoint Base Station Unit are designed to
directly mount to 1-1/2 inch to 3 inch pole diameters (outer diameter).
For mounting directly to a proper size pole, first attach the bottom mounting bracket
to the pole using the retainer as seen below while keeping the unit upright (lash to pole
or keep hosting rope in place). Then attach the ODU to the pole using the upper
mounting bracket, and lock into position by tightening the bottom bracket screws and
the upper arm bolts using the supplied mounting nuts. To adjust the up/down tilt,
move the arm nuts and bracket until at the right angel and then tighten all nuts as
shown. See photos and diagrams below for detail. Connect the weatherproof circular
connector from the cable from the power unit to the bottom of the ODU assembly.
Note:
Different diameter poles require
different mounting techniques.
Adapt the mounting brackets
according to the mounting pole
diameter. If the pole diameter is
larger than can be accommodated
(>3.00”), use a pair of extenders
and mount a smaller diameter
pole parallel to the thicker pole
and away from the tower.
GPS antenna connection on top
of the BSU ODU. Remove water
protection cap and connect the
GPS cable with antenna.
Figure 4-2: Base Station Unit ODU mounting detail
FLAT SURFACE MOUNTING
For mounting to a flat surface, attach mounting bracket to the SU using bolts
supplied, and then mount to flat surface using your own hardware.
GPS ANTENNA MOUNTING
For operation with multiple base stations, the frame timing of all BSUs must be
synchronized using GPS. The GPS antenna (small metal plate with black 2x2”
antenna with thin cable) must be connected to the SMA connector on top of the
ODUnit (see drawing above). Find a location nearby where the antenna plate can be
mounted and secured with the black antenna bump up and the plate parallel to the
earth/horizon. This small antenna needs to see as much of the sky as possible to

T S U N A M I
M U L T I P O I N T
acquire at least one GPS satellite to extract timing signals for the ODU transmission
synchronization.
Figure 4-3: ODU with GPS antenna
Each BSU ODU must have its GPS antenna attached and mounted as described
above.
Figure 4-4: Base Station ODU
Connect the supplied cable between the ODU (pictured above) and the power unit
mounted near your PC or network. The ODU cable to the inside power unit may be
of two different styles (see Figures 2-12 and 2-13). Whichever cable, connect the
ODU with the larger of the connectors by aligning the plastic slot and then handtighten the outside ring to secure and seal the connector to the ODU.
