This section describes important safety and regulatory guidelines that must be
observed by personnel installing or operating PTP 250 equipment.
I m port ant safet y inform at ion
WARNING
To prevent loss of life or physical injury, observe the safety guidelines
in this section.
Pow er line s
Exercise extreme care when installing antennas near power lines.
W ork ing at he ight s
Exercise extreme care when working at heights.
Grounding and pr ot e ctive e a rt h
The Outdoor Unit (ODU) must be properly grounded to protect against lightning. It is
the user’s responsibility to install the equipment in accordance with national
regulations. In the USA, follow Section 810 of the
National Electric Code, ANSI/NFPA
No.70-1984
(USA). In Canada, follow Section 54 of the
Canadian Electrical Code
.
These codes describe correct installation procedures for grounding the outdoor unit,
mast, lead-in wire and discharge unit, size of grounding conductors and connection
requirements for grounding electrodes. Other regulations may apply in different
countries and therefore it is recommended that installation of the outdoor unit be
contracted to a professional installer.
Safet y and Regulatory
phn- 2 182_002v 000
I I May 2011
Using t he cor r e ct pow er supply
Always use the Motorola Power over Ethernet injector unit (PoE power supply) or
Powered Indoor Unit (PIDU Plus) to power the ODU. Failure to use the correct power
supply could result in equipment damage and will invalidate the safety certification
and may cause a safety hazard.
Alt ernat ive DC supply
If the PTP 250 is to be powered from a DC supply (either as the primary power source
or as a backup to the AC supply), the DC supply must be input to the ODU via a PIDU
(not a PoE power supply). The DC supply must be connected to the PIDU DC IN
terminals. The DC supply must comply with the following requirements:
• The voltage and polarity is correct and is applied to the correct terminals in the
PIDU.
• The power source is rated as Safety Extra Low Voltage (SELV).
• The power source is rated to supply at least 1 A continuously.
• The power source cannot provide more than the Energy Hazard Limit as defined
by IEC/EN/UL60950-1, Clause 2.5, Limited Power (The Energy Hazard Limit is
240VA).
Pow ering dow n be fore servicing
Always power down and unplug the equipment before servicing.
Lightning pr ot e ction unit ( LPU)
Do not remove the LPU printed circuit board when the LPU is connected to the power
supply, as high voltages are present.
N on - M ot orola pow e r supply
Safety may be compromised if a different power supply is used than the one supplied
by Motorola as part of the system.
Safet y and Regulatory
phn- 2182_002v000
May 2011 III
Drop ca ble t este r
The drop cable tester must NEVER be used at the ODU end connected to power from
the PoE power supply. It must only be used at the bottom of the mast with a
multimeter. This is because the PoE power supply voltage exceeds the limit allowed in
some countries for safe handling in wet conditions and therefore may create a safety
hazard.
Prim ary disconne ct de vice
The main power supply is the primary disconnect device.
Ex t ernal ca bles
Safety may be compromised if outdoor rated cables are not used for connections that
will be exposed to the outdoor environment.
RF exposure nea r t he a nt e nna
Strong radio frequency (RF) fields will be present close to the antenna when the
transmitter is on. Always turn off the power to the ODU before undertaking
maintenance activities in front of the antenna.
Minim um sepa ra t ion dist a nces
Install the ODUs so as to provide and maintain the minimum separation distances from
all persons.
The minimum separation distances for each frequency variant are specified in
Calculated distances and power compliance margins on page 4-25.

I V May 2011
I m port ant r e gulat or y inform a t ion
Operation of the PTP 250 product involves its use as an unlicensed device in frequency
bands where it is not allowed to cause interference to licensed services (called primary
users of the bands).
Radar a voida nce
In some countries radar systems are the primary users and the regulators have
devised special requirements to protect their operation from interference caused by
unlicensed devices. The unlicensed devices are required to detect the presence of
radar systems and avoid co-channel operation with the radar systems.
The PTP 250 system provides detection and avoidance functionality for countries and
frequency bands requiring protection for radar systems.
Installers and users are reminded that they must follow local regulations with regard
to any requirements for radar detection as well as transmitted power level. This can
be achieved by using the correct country code for the product concerned. Failure to
follow this could leave the installer and/or user liable to civil and/or criminal penalties.
Contact the Motorola helpdesk if you are unsure about any specific areas where you
need guidance.

This section introduces the key features, typical uses, product variants and
components of the PTP 250.
Purpose
Motorola PTP 250 products are designed for Ethernet bridging over point-to-point
microwave links in the unlicensed bands 5.4 GHz (ETSI Band B) and 5.8 GHz (ETSI
Band C and FCC ISM band). Users must ensure that the links comply with local
operating regulations.
The PTP 250 is used to create a transparent bridge between two segments of the
operator’s network. This bridge can be treated as a virtual wired connection between
two points.
Key feat ur e s
The key features of the PTP 250 include:
• Orthogonal Frequency Division Multiplexing (OFDM) modulation and Multiple-
Input Multiple-Output (MIMO) techniques.
• Wireless connections of up to 54 km (34 miles) in near line-of-sight conditions.
• High link availability, through the use of adaptive modulation techniques that
dynamically reduce the data rate in severe or adverse conditions.
• High-sensitivity antennas for improved signal recovery.
• A built-in web server for advanced management capabilities including detailed
radio signal diagnosis.
• Password control and encryption.
Be nefit of t he chosen bands
The products operate in bands that offer the dual benefits of high data throughput and
good radio propagation characteristics. The wide band of spectrum available is
subdivided into several channels such that multiple systems can operate in the vicinity
without causing interference to one another.

8 0 2 .1 1 n device
PTP250 uses 802.11n encoding and radio transmission. In areas where the PTP 250
co-exists with 802.11a and 802.11n devices, the PTP 250 detects the 802.11a and
802.11n radio signals and chooses a clear channel away from any interference.
Avoiding int erference from nearby de vices
At initialization, the products monitor the available frequency channels to find a
channel that is clear of interference.
Typical deploym e nt
The PTP 250 bridge consists of a pair of identical units, one deployed at each end of
the link. The radio link operates on a single frequency channel. One unit is configured
as a master and the other as a slave. The master unit takes responsibility for
controlling the link in both directions.
The bridge is aimed at a wide range of applications. One example is an enterprise that
needs to connect together the Local Area Network (LAN) of two or more buildings as
shown in Figure 1-1.

1-4 May 2011
System com ponent s
Each end of the link consists of:
• Outdoor Unit (ODU): An integrated (or connectorized) outdoor transceiver unit
containing all the radio and networking electronics.
• PoE power supply: An indoor connection box containing a mains power supply,
status indicators and network connection port.
• Cabling and lightning protection: CAT5e cables, grounding cables, connectors
and a lightning protection unit (LPU).
Product va ria nt s
The PTP 250 is available in the following product variants:
• FCC/IC or ETSI/RoW: The PTP 250 is available in two regional variants: one is
for use in countries where FCC or IC licensing restrictions apply (FCC/IC), and
the other is for use in ETSI countries or the rest of the world (ETSI/RoW). The
regional variants may operate in the following bands:
o ETSI/RoW: 5.4 GHz or 5.8 GHz.
o FCC/IC: 5.8 GHz only.
• Integrated or Connectorized: Both products are available in either Integrated
(with attached antenna) or Connectorized (without an antenna) variants.
• Link Complete or End Complete: The Link Complete kit consists of two ODUs
and two PoE power supply units. The End Complete kit consists of one ODU and
one PoE power supply unit.
To obtain part numbers for the above variants, refer to Installation inventories on page
4-2.

The connectorized ODU also has interfaces to connect to an external antenna (Figure
1-5) via an N type connector with RF cable of type LMR100, LMR200, LMR300,
LMR400 or LMR600. The ‘V’ interface is for vertical polarization and the ‘H interface
is for horizontal polarization.
Figure 1 - 5 Connect orized ODU antenna int erfaces
Mount ing bra cket s
The ODU is supplied with a bracket for mounting it to a pole of 50mm (2”) to 75mm
(3”) in diameter.
The bracket allows for adjustment in both azimuth and elevation. The bracket may be
split to allow the pole mount section of the bracket to be mounted to the pole first.
This allows the installer to take the weight of the unit and secure it, one handed, with
a single mounting bolt.
N e t w ork conne ct ion
The network connection to the ODU is made via a 1000BaseT (Gigabit) Ethernet
connection. Power is provided to the ODU over the 1000BaseT Ethernet connection
using a standard IEEE 802.3at power supply.

This section describes the cabling and lightning protection components of PTP 250
installations.
PTP and light ning pr ot e ct ion
The PoE power supply meets the low level static discharge specifications identified in
Electromagnetic compatibility (EMC) compliance on page 4-22 but does not provide
lightning or surge suppression.
The amount of lightning protection is dependent on regulatory and end user
requirements. The standard ODU is fitted with surge limiting circuits and other
features to minimize the risk of damage due to nearby lightning strikes. To be fully
effective, these standard features require some additional equipment to be configured
as part of the system installation.
WARNING
The units are not designed to survive direct lightning strike. For this reason
they must not be installed in ‘Zone A’, as defined in Lightning protection
zones on page 2-11. Mounting in Zone A may put equipment, structures and
life at risk.
Out door connections
The term ‘drop cable’ refers to the cable that is used for all connections that terminate
outside the building, for example, connections between the ODU, LPU and PoE power
supply.
CAUTION
For outdoor connections, always use Cat5e cable that is gel-filled and
shielded with copper-plated steel. This is the only type of outdoor drop cable
supported in this application.

I ndoor connections
The CAT5e cable that connects the PoE power supply to the network equipment must
meet the following requirements:
• Screening: Must be either foil screen (FTP) or braided screen (STP) cable.
• Connectors: Must use screened RJ45 connectors with metal shells at both ends.
• Electrical connection: There must be a continuous electrical connection
between both screened connectors.
CAUTION
The connected network equipment must feature screened RJ45
connectors and must be connected to ground, otherwise the PoE power
supply will not be grounded, and this may increase the levels of unwanted
radiation from the ODU - PoE power supply cables.
Cable grounding k it s
Drop cables must be grounded at the points specified in Grounding and lightning
protection on page 2-11. One cable grounding kit (Figure 1-8) is required for each
drop cable grounding point.

W ireless ope rat ion
This section describes how PTP 250 wireless links are operated, including modulation
modes, power control and security.
W ireless Tra nsm ission s
The PTP 250 uses Time Division Duplexing (TDD) transmission, which means that a
single frequency channel is used for both Transmit and Receive. This is handled
automatically by the radio.
The PTP 250 transmits using Orthogonal Frequency Division Multiplexing (OFDM).
This wideband signal consists of many equally spaced sub-carriers. Although each
sub-carrier is modulated at a low rate using conventional modulation schemes, the
resultant data rate from all the sub-carriers is high.
The channel width of the OFDM signal is configurable to one of two values: 20 MHz or
40 MHz. The higher channel width provides greater link capacity at the expense of
using more spectrum. The lower channel width provides better receiver sensitivity and
can also be appropriate where the amount of free spectrum is limited.
Each channel is offset in center frequency from its neighboring channel by 20 MHz.
Spe ct r um m ana gem ent
At system start-up, the spectrum management feature of the PTP 250 monitors the
available wireless spectrum and directs both ends of the wireless link to operate on a
channel with a minimum level of co-channel and adjacent channel interference.
Alternatively, the user can specify a single channel to use (or several to be chosen
from) at the master unit.
Adapt ive m odula t ion
The PTP 250 can transport data over the wireless link using different modulation
modes. For a given channel width, each modulation mode transports data at a fixed
rate. Also, the receiver requires a given signal to noise ratio in order to successfully
demodulate a given modulation mode. Although the more complex modulations will
transport data at a much higher rate than the less complex modulation modes, the
receiver requires a much higher signal to noise ratio.
Wir eless operation Chapt er 1 Product descr ipt ion
phn- 2 182_002v 000
1-18 May 2011
The system provides an adaptive modulation scheme where the receiver constantly
monitors the quality of the received signal and notifies the far end of the link of the
optimum modulation mode with which to transmit. In this way, optimum capacity is
achieved at all times.
NOTE
PTP LINKPlanner includes an estimate of mean data rate, the data rate
provided by each modulation and the percentage of time spent in each
modulation mode.
MI MO
Multiple-Input Multiple-Output (MIMO) techniques provide protection against fading
and increase the probability that the receiver will decode a usable signal. When the
effects of MIMO are combined with those of OFDM techniques and a high link budget,
there is a high probability of a robust connection.
The PTP 250 transmits two signals on the same radio frequency, one of which is
vertically polarized and the other horizontally polarized. The system also has the
ability to adapt between two modes of operation:
• Dual Payload: When the radio channel conditions allow, the system will transmit
two different and parallel data streams, one on the vertical channel and one on
the horizontal channel. This doubles the capacity of the system.
• Single Payload: As the radio channel becomes more challenging, the system has
the ability to detect this and switch to a mode which transmits the same data
stream on both vertical and horizontal channels. This provides polar diversity and
is another key feature which allows the system to operate in challenging radio
channels.
The switching between modes is automatically controlled by the adaptive modulation
feature described in Adaptive modulation on page 1-17.

Ra da r a voida nce
In regions where protection of radars is part of the local regulations, the PTP 250 must
detect interference from radar-like systems and avoid co-channel operation with these
systems.
To meet this requirement, the PTP 250 implements the following features:
ETSI regulat ions
The regulations have radar detection requirements for both master and slave devices.
The requirements for a master device are:
• The device can only transmit on available channels, of which there are none at
initial power up. The radar detection algorithm will always scan a usable channel
for 60 seconds (channel availability check) for radar interference before making
the channel an available channel.
• As a result of this compulsory channel scan, there is a service outage of at least
60 seconds every time radar is detected, and the installation time is extended by
at least 60 seconds even if no radar is detected on the channel.
• When operating on a channel, the spectrum monitoring algorithm implements a
radar detection function (in-service monitoring) which looks for impulsive
interference on the operating channel. If impulsive interference is detected,
spectrum management will mark the current operating channel as having
detected radar (unavailable channel) and initiate a channel hop to an available
channel. The previous operating channel will remain in the unavailable state for
30 minutes after the impulsive interference pulse was detected.
• After the 30 minutes have expired the channel will be returned to the usable
channel
pool.
• There is a secondary requirement for bands requiring radar avoidance.
Regulators have mandated that products provide an approximately even loading
of the spectrum across all devices. In general, this prevents operation with fixed
frequency allocations. However, ETSI regulations do allow frequency planning of
networks (as that has the effect of spreading the load across the spectrum).
NOTE
The Master device will not initiate any transmissions on channels which
overlap the band 5600-5650 MHz as the radar detection requirements are
more severe.
Wir eless operation Chapt er 1 Product descr ipt ion
phn- 2 182_002v 000
1-20 May 2011
The requirements for a slave device are:
• The slave device can only transmit after receiving a transmission from its
associated master to demonstrate that the channel is an available channel.
• The slave device is required to vacate the channel when the master device has
detected a radar signal.
• The slave device is also required to perform in-service monitoring
and will stop
transmitting on a channel having detected a radar signal (having informed the
master device) and will not re-use the channel for thirty minutes.
• Once the slave device has detected a radar on a channel, it will perform a
channel availability check
before transmitting again on the channel.
• The slave device is also required to perform Channel Availability Check (CAC)
measurements before responding to a master transmission, but this requirement
only applies after the slave has detected a radar signal on the channel.
Securit y
The PTP 250 supports 48-bit proprietary encryption for data transmitted over the
wireless link.
Count r y of operat ion
Some aspects of wireless operation are controlled, enforced or restricted according to
country of operation.
The Country Code must be set in the user interface by the user at first login. The
Country Code setting affects the following aspects of wireless operation:
• Maximum transmit power
• Radar avoidance
• Transmit power reduction in edge channels
• Frequency range
• Channel plan
CAUTION
To avoid possible enforcement action by the country regulator, always
operate links in accordance with local regulations.

NOTE
Equipment supplied to the USA can ONLY be set to operate with a Country
Code which is fully compatible with FCC Rules.
Using fr e quency planning
Networks will benefit from the use of fixed channel allocations if (a) the network
consists of multiple PTP links, and (b) RF interference predominantly arises from
equipment in the same network.
Frequency planning is the exercise of assigning operating channels to PTP units so as
to minimize RF interference between links. Frequency planning must consider
interference from any PTP unit to any other PTP unit in the network. Low levels of
interference normally allow for stable operation and high link capacity.
The frequency planning task is made more straightforward by use of the following
techniques:
• Using several different channels
• Separating units located on the same mast
• Using high performance (directional) external antennas
For help with planning networks, refer to Chapter 2 Planning considerations, or
contact a Motorola distributor or re-seller.

Cust om er ne t w ork
Tr a nspare nt Et hernet service
The PTP 250 provides an Ethernet service between the Ethernet port at a local ODU
and the Ethernet port at an associated remote ODU. The Ethernet service is based on
conventional layer two transparent bridging, and is equivalent to the Ethernet Private
Line (EPL) service defined by the Metro Ethernet Forum (MEF).
The service is transparent to untagged frames, standard VLAN frames, priority-tagged
frames, provider bridged frames, and provider backbone bridged frames. In each case,
the service preserves MAC addresses, VLAN ID, Ethernet priority and Ethernet
payload in the forwarded frame. The maximum frame size for bridged frames is
2000 octets.
Layer t w o cont rol pr ot ocols
The PTP 250 is transparent to layer two control protocols (L2CP) including:
• Spanning tree protocol (STP), rapid spanning tree protocol (RSTP)
• Multiple spanning tree protocol (MSTP)
• Link aggregation control protocol (LACP)
• Link OAM, IEEE 802.3ah
• Port authentication, IEEE 802.1X
• Ethernet local management interface (E-LMI), ITU-T Q.933.
• Link layer discovery protocol (LLDP)
• Multiple registration protocol (MRP)
• Generic attribute registration protocol (GARP)
The system does not generate or respond to any L2CP traffic.

Ethernet bridging behavior at each end of the wireless link is equivalent to a two-port,
managed, transparent MAC bridge where the two ports are:
• Ethernet Port
• Wireless Port
Frames are transmitted at the Wireless port over a proprietary point-to-point circuit-
mode link layer between ends of the link. Ethernet frames received at the Ethernet
port, or generated internally within the management agent, are encapsulated within a
lightweight MAC layer for transmission over the wireless link.
Protocol layers involved in bridging between Ethernet and wireless interfaces are

Spectrum planning
This section describes the regulatory restrictions that affect radio spectrum usage.
Each frequency variant has specific regulatory restrictions that affect frequency range,
radar avoidance and channel width usage.
Ava ila ble spect r um
Ensure the link is configured to conform to local regulatory requirements.
The available spectrum for operation depends on the country of operation:
• The 5.4 GHz band is available in all EU countries.
• The 5.8 GHz band is currently only available in a limited number of EU countries
(UK, Eire, Norway, Denmark, Germany and Spain).
Certain regulations have allocated certain channels as unavailable for use:
• Europe has allocated part of the 5.4 GHz band to weather radar.
• The UK and some other European countries have allocated part of the 5.8 GHz
band to Road Transport and Traffic Telematics (RTTT) systems.
For examples of these restrictions, refer to Examples of regulatory limits on page 4-32.
Where regulatory restrictions apply to certain channels, these channels are barred
automatically by the use of the correct country setting. For example, at 5.8 GHz in the
UK and some other European countries, the RTTT band 5795 MHz to 5815 MHz is
barred. With the appropriate configuration for a country in this region, the PTP 250
will not operate on channels within this band.
The number and identity of channels barred by the country selection is dependent on
the channel width selected.
NOTE
For the connectorized model, when using external antennas of higher gain
than the appropriate integrated antenna, the regulations may require the
maximum transmit power to be reduced. To ensure that regulatory
requirements are met for connectorized installations, refer to Calculating
EIRP for connectorized units on page 4-30.

Frequency selection
The PTP 250 fully conforms to regional regulatory requirements for radar avoidance.
In regions that mandate DFS, the unit first ensures that there is no radar activity on a
given channel for a period of 60 seconds before radiating on that channel. Once a
channel has been selected for operation, the unit will continually monitor for radar
activity on the operating channel. If detected, it will immediately cease radiating and
attempt to find a new channel.
Radar avoidance requirements in the 5.4 GHz band are defined as follows:
• For the EU: in specification EN 301-893 version V1.5.1.
Radar avoidance at 5.8 GHz is applicable to EU operation (not FCC/IC) and the
requirements are defined in EN 302 502.
Cha nnel w idt h
Select the required channel width for the link (20 MHz or 40 MHz). The wider channel
has the greater the capacity. As narrower channel widths take up less spectrum,
selecting a narrow channel width may be a better choice when operating in locations
where the spectrum is very busy.

Sit e pla nning
This section describes factors to be taken into account when choosing sites for the
ODU and PoE power supply.
ODU sit e selection
When selecting a site for the ODU, consider the following factors:
• Height and location to ensure that people are kept away from the antenna; see
Calculated distances and power compliance margins on page 4-25.
• Height and location to achieve the best radio path.
• Ability to meet the requirements specified in Grounding and lightning protection
on page 2-11.
• Aesthetics and planning permission issues.
• Cable lengths; see Maximum cable lengths on page 2-5.
• The effect of strong winds on the installation; see Wind loading on page 2-5.
Pow e r supply sele ct ion
Select a suitable power supply unit for the PTP 250. The only supported units are the
PoE power supply (included in PTP 250 kits) or the PTP 300/500/600 Series PIDU. The
PoE power supply is suitable for the majority of installations, but the PIDU is required
in the following situations:
• When a -48 V DC power supply is required, either as the primary supply or as a
backup to the AC mains.
• When an extended operating temperature range is required for the mains
powering system, for example when the indoor equipment is in a building without
temperature control or air conditioning.
For PIDU ordering information, see Alternative components on page 4-9.
The power supply unit must be installed in an indoor location with no possibility of
condensation, with an ambient temperature within the specified operating range of the
product; see Power supply unit specifications on page 4-12.

Ensure that the supporting structure will not be prone to excessive wind loading.
Antennas and equipment mounted on towers or buildings will subject the mounting
structure to significant lateral forces when there is appreciable wind. Antennas are
normally specified by the amount of force (in pounds) for specific wind strengths. The
magnitude of the force depends on both the wind strength and size of the antenna.
The ODU, with or without the integral antenna, is essentially a flat structure. The

Link pla nning
This section describes factors to be taken into account when planning links, such as
range, obstacles and path loss. PTP LINKPlanner is recommended.
Ra nge and obst a cle s
Calculate the range of the link and identify any obstacles that may affect radio
performance.
Perform a survey to identify all the obstructions (such as trees or buildings) in the path
and to assess the risk of interference. This information is necessary in order to achieve
an accurate link feasibility assessment.
NOTE
When higher gain connectorized antennas are used, reduce the transmit
power to ensure that the receiver signal level does not exceed -20 dBm.
PTP LI N KPla nner
The Motorola PTP LINKPlanner software and user guide may be downloaded from
http://www.motorola.com/ptp/support.
PTP LINKPlanner imports path profiles and predicts data rates and reliability over the
path. It allows the system designer to try different antenna heights and RF power
settings. It outputs an installation report that defines the parameters to be used for
configuration, alignment and operation. The installation report can be used to compare
the predicted and actual performance of the link.

Pat h loss considerat ions
Path loss is the amount of attenuation the radio signal undergoes between the two
ends of the link.
Calculat ing pa t h loss
The path loss is the sum of the attenuation of the path if there were no obstacles in the
way (Free Space Path Loss), the attenuation caused by obstacles (Excess Path Loss)
and a margin to allow for possible fading of the radio signal (Fade Margin). The
calculation of Equation 2-1 needs to be performed to judge whether a particular link
can be installed.

Adaptive modulation ensures that the highest throughput that can be achieved
instantaneously will be obtained, taking account of propagation and interference.
When the link has been installed, web pages provide information about the link loss
currently measured by the equipment, both instantaneously and averaged. The
averaged value will require maximum seasonal fading to be added, and then the radio
reliability of the link can be computed.

W hen t o install connector ized unit s
The majority of radio links can be successfully deployed with the integrated PTP 250.
However the integrated units may not be sufficient in some areas, for example:
• Where the path is heavily obscured by dense woodland on an NLOS link.
• Where long LOS links (>23 km or >14 miles) are required.
• Where there are known to be high levels of interference.
PTP LINKPlanner can be used to identify these areas of marginal performance.
In these areas, connectorized ODUs and external antennas should be used.
The external antennas can be either dual-polarization (as the integrated antenna) or
two single polarized antennas can be used in a spatially diverse configuration. It is
expected that the dual-polarization antennas would normally be used to simplify the
installation process; spatially diverse antennas may provide additional fade margin on
very long LOS links where there is evidence of correlation of the fading characteristics
on Vertical and Horizontal polarizations.

Grounding and light ning prot ection
Structures, equipment and people must be protected against power surges (typically
caused by lightning) by conducting the surge current to ground via a separate
preferential solid path.
The actual degree of protection required depends on local conditions and applicable
local regulations.
Motorola recommends that PTP 250 installation is contracted to a professional
installer.
WARNING
Electro-magnetic discharge (lightning) damage is not covered under
warranty. The recommendations in this guide, when followed
correctly, give the user the best protection from the harmful effects
of EMD. However 100% protection is neither implied nor possible.
Sta ndards
Full details of lightning protection methods and requirements can be found in the
international standards IEC 61024-1 and IEC 61312-1, the U.S. National Electric Code
ANSI/NFPA No. 70-1984 or section 54 of the Canadian Electric Code.
Light ning pr ot e ct ion zone s
The ‘rolling sphere method’ (Figure 2-1) is used to determine where it is safe to mount
equipment. An imaginary sphere, typically 50 meters in radius, is rolled over the
structure. Where the sphere rests against the ground and a strike termination device
(such as a finial or ground bar), all the space under the sphere is considered to be in
the zone of protection (Zone B). Similarly, where the sphere rests on two finials, the
space under the sphere is considered to be in the zone of protection.

Figure 2 - 1 Rolling sphere m ethod to determ ine t he light ning protect ion zones
Assess locations on masts, towers and buildings to determine if the location is in Zone
A or Zone B:
• Zone A: In this zone a direct lightning strike is possible. Do not mount equipment
in this zone.
• Zone B: In this zone, direct EMD (lightning) effects are still possible, but
mounting in this zone significantly reduces the possibility of a direct strike.
Mount equipment in this zone.
WARNING
Never mount equipment in Zone A. Mounting in Zone A may put
equipment, structures and life at risk.

Ba sic r e quir e m ent s
The following basic protection requirements must be implemented:
• The ODU must be in ‘Zone B’ (see Lightning protection zones on page 2-11).
• A lightning protection unit (LPU) must be installed within 600 mm (24 in) of the
point at which the drop cable enters the building or equipment room.
• The drop cable must be bonded to the supporting structure in order to prevent
lightning creating a potential between the structure and cable, which could
cause arcing, resulting in fire risk and damage to equipment.
• The drop cable must be grounded at the building entry point.
• The drop cable must not be laid alongside a lightning air terminal.
• All grounding cables must be a minimum size of 10 mm2 csa (8AWG), preferably
16 mm2 csa (6AWG), or 25 mm2 csa (4AWG).
Grounding ca ble require m ent s
When routing, fastening and connecting grounding cables, the following requirements
must be implemented:
• Grounding conductors must be run as short, straight, and smoothly as possible,
with the fewest possible number of bends and curves.
• Grounding cables must not be installed with drip loops.
• All bends must have a minimum radius of 203 mm (8 in) and a minimum angle of
90° (Figure 2-2). A diagonal run is preferable to a bend, even though it does not
follow the contour or run parallel to the supporting structure.
• All bends, curves and connections must be routed towards the grounding
electrode system, ground rod, or ground bar.
• Grounding conductors must be securely fastened.
• Braided grounding conductors must not be used.
• Approved bonding techniques must be used for the connection of dissimilar
metals.

If the ODU is to be mounted on a metal tower or mast, then in addition to the general
protection requirements (above), the following requirements must be observed:
• The equipment must be lower than the top of the tower or its lightning air
terminal.
• The metal tower or mast must be correctly grounded.
• A grounding kit must be installed at the first point of contact between the drop
cable and the tower, near the top.
• A grounding kit must be installed at the bottom of the tower, near the vertical to
horizontal transition point. This grounding kit must be bonded to the tower or
tower ground bus bar (TGB), if installed.
• If the tower is greater than 61 m (200 ft) in height, an additional grounding kit
must be installed at the tower midpoint. Additional ground kits must be installed
as necessary to reduce the distance between ground kits to 61 m (200 ft) or less.

addition to the general protection requirements (above), the following requirements
must be observed:
• The ODU must be below the lightning terminals and finials.
• A grounding conductor must be installed around the roof perimeter, to form the
main roof perimeter lightning protection ring.
• Air terminals are typically installed along the length of the main roof perimeter
lightning protection ring typically every 6.1 m (20 ft).
• The main roof perimeter lightning protection ring must contain at least two down
conductors connected to the grounding electrode system. The down conductors
should be physically separated from one another, as far as practical.

Da t a ne t w ork planning
This section describes factors to be considered when planning PTP 250 data networks.
I P int erfa ce
Choose an IP address for the IP interface of the ODU management agent. The IP
address must be unique and valid for the connected network segment.
Ensure that the design of the data network permits bi-directional routing of IP
datagrams between network management systems and the ODUs. For example, ensure
that the gateway IP address identifies a router or other gateway that provides access
to the rest of the data network.
Back t o back link s
Do not use direct cabled connections between the data ports of two PoE power
supplies. Where two or more links are deployed in a chain, always use an Ethernet
switch or router to interconnect the links at a relay point.
‘Green Et hernet ’ sw it ches
Do not connect PTP 250 units to Ethernet networking products that control the level of
the transmitted Ethernet signal based on the measured length of the Ethernet link, for
example Green Ethernet products manufactured by D-Link Corporation. The Ethernet
interfaces in these networking products do not work correctly when connected directly
to the PoE power supply.

Ant e nna specificat ions
This section contains specifications of the antennas that are approved by the FCC for
use with the connectorized ODUs.
Ant e nna selection crit eria
The main selection criterion is the required antenna gain. The secondary criterion is
the ease of mounting and alignment. For example, the Radio Waves Parabolic dishes
are supplied with a mount that allows adjustment for alignment independent of the
actual antenna mounting. This type of antenna is much easier to align than those that
have to be rotated around the mounting pole for alignment.
N on - FCC r egions
In non-FCC regions, antenna choice is not restricted, but any region specific EIRP limit
must be obeyed by reducing the maximum transmit power, see Calculating EIRP for
connectorized units on page 4-30.
FCC re gions
In FCC regions, antenna choice is restricted as described in 5.8 GHz FCC antenna
restrictions on page 4-15.
The maximum permitted antenna gain depends upon product variant and channel
width, as specified in Calculating EIRP for connectorized units on page 4-30.

5 .8 GHz FCC ant enna restrictions
In FCC regions in the 5.8 GHz band, external antennas from the lists in Table 4-13 can
be used with the Connectorized version of the PTP 250. These are approved by the
FCC for use with the product and are constrained by the following limit for Single/Dual
Polarization Parabolic Dish Antennas: up to 37.6 dBi per polarization or antenna.
In FCC regions when using external antennas, cable loss between the connectorized
ODU and the antenna ports must not be less than 1.2 dB.
CAUTION
Antennas not included in this table, or those having a gain greater than the
specified maximum, are strictly prohibited for use with the PTP 250 in the
5.8 GHz band. The required antenna impedance is 50 ohms.

Ra dio a nd t elevision int erference
If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged
to try to correct the interference by one or more of the following measures:
• Reorient or relocate the Outdoor Unit (ODU).
• Increase the separation between the affected equipment and ODU.
• Connect the ODU and PoE power supply into a power outlet on a circuit different
from that to which the receiver is connected.
• Consult your installer or supplier for help.
Max im um pe r m it t ed EI RP
In most countries, operation of products in the band 5470 MHz to 5725 MHz is
constrained by an EIRP limit. The constraint is that the EIRP must not exceed 30 dBm
or (17 + 10 x Log Channel width) dBm.
In some countries, operation of products in the band 5725 MHz to 5875 MHz is
constrained by an EIRP limit. The constraint is that the EIRP must not exceed 36 dBm
or (23 + 10 x Log Channel width) dBm.
For examples of countries that impose an EIRP limit, refer to Table 4-23.

Calcula t ing EI RP for connector ized unit s
When operating with external antennas in countries that impose an EIRP limit, the
administrator has to set the maximum transmit power to ensure that EIRP does not
exceed the limit allowed by regulations.
To calculate the maximum EIRP that the unit can output, use this formula:
Maximum EIRP (dBm) =
Maximum Power Level (dBm) + Antenna Gain (dBi) – Cable Loss (dB)
To calculate the highest permissible setting of Maximum Power Level, use this
formula:
Maximum Power Level (dBm) =
Allowed EIRP (dBm) – Antenna Gain (dBi) + Cable Loss (dB)

Prior to alignment, ensure that the following parameters are available:
• Location of both sites (latitude and longitude).
• Bearing to the other end of the link for both sites.
• Prediction of receive signal level for both ends of the link.
• Prediction of link loss.
PTP LINKPlanner provides all of these parameters in the form of an installation report.
If a connectorized ODU is installed at either site with two separate antennas for spatial
diversity, refer to Aligning separate antennas for spatial diversity on page 6-27 before
starting alignment.

NOTE
To achieve best results, make small incremental changes to elevation and
azimuth.
CAUTION
The action of tightening the mounting bolts can alter antenna alignment.
This can be helpful when fine-tuning alignment, but it can also lead to
misalignment. To prevent misalignment, continue to monitor receive signal
level during final tightening of the bolts.
To align the antennas, proceed as follows:
1 At each end of the link, adjust the antenna to point at the other end of the
link. This should be done with the aid of a compass.
2 Without moving the master antenna, adjust the elevation and azimuth of the
slave antenna to achieve the highest receive signal level (using one of the
recommended methods in Monitoring received signal level on page 6-27).
3 Without moving the Slave antenna, adjust the elevation and azimuth of the
Master antenna to achieve the highest receive signal level (using one of the
recommended methods).
4 Repeat steps 2 and 3 as necessary to fine-tune the alignment to find the
center of the beam.
5 When the antennas have been aligned on the center of the beam, verify that
the receive level is within the predicted range (from the installation report).
If this is not the case, go back to step 2.
The current value of receive level can be verified by using Graphical
alignment on page 6-29 or by selecting menu option Status and monitoring
the Receive Power attribute on the System Status page.
6 If after repeated attempts to align, the receive level still does not lie within
the predicted range, this may be because the data provided to the
prediction tool (such as PTP LINKPlanner) is inaccurate. For example
estimates of path obstructions, antenna heights or site locations may be
inaccurate. Check this data and update the prediction as necessary.
7 Once the antennas have been aligned correctly, tighten the integrated ODU
(or connectorized antenna) mountings. To ensure that the action of
tightening does not alter antenna alignment, continue to monitor received
signal level.

The ODU emits audible tones during installation to assist with alignment. The pitch of
the alignment tone is proportional to the received power of the wireless signals. Adjust
the alignment of the unit, in both azimuth and elevation, until the highest pitch tone is
achieved.
The tones and their meanings are described in Table 6-5. In each of the states detailed
in the table, align the unit to give the highest pitch tone.

V/H Ratio The maximum, mean, minimum and latest measurements of
V/H Ratio. See Diagnostics calculated over time on page 7-23.
This is calculated from:
Power received by the vertical antenna input (dB) ÷
Power received by the horizontal antenna input (dB)
V/H Ratio is an aid to debugging a link. If it has a large
positive or negative value, then investigate the following
potential problems:
An antenna coaxial lead may be disconnected.
When spatial diversity is employed, the antenna with the
lower value may be pointing in the wrong direction.
When a dual polar antenna is deployed, the antenna may
be directed using a side lobe rather than the main lobe.
When there is a reflection from water on the link and spatial
diversity is employed, then one expects large, slow swings in
V/H Ratio. This indicates the antenna system is doing exactly
as intended.
Transmit Data
Rate
The maximum, mean, minimum and latest measurements of
Transmit Data Rate (Mbps). See Diagnostics calculated over

Recovering a lost I P a ddress
To recover a lost IP address, physical access to the PoE power supply is recommended.
NOTE
The unit does still respond to its normal IP address through a power cycle.
If the IP address of the unit has been lost or forgotten, proceed as follows:
1 Set the management PC Ethernet port to an IP address that is valid for
the 169.254.X.X network, avoiding 169.254.0.0, 169.254.1.1 and
169.254.1.2. Refer to Configuring the management PC on page 6-3.
2 Connect the management PC Ethernet port to the DATA IN port of the
PoE power supply using a standard (not crossed) Cat5e cable (Figure
6-3).
3 Perform a power cycle, that is, disconnect and then reconnect the PoE
power supply to its AC supply.
4 Access the web interface within 30 seconds of powering on, using default
IP address 169.254.1.1.
5 Select menu option Configuration, LAN Configuration.
6 Obtain the correct IP address of the unit from the LAN Configuration
page.

This section describes how to test the link end hardware, either when it fails on
startup, or after a lightning strike.
Before testing link end hardware, confirm that all outdoor drop cables, that is those
that connect the ODU to equipment inside the building, are of the supported type, as
defined in Installation inventories on page 4-2.
NOTE
These tests apply to installations that use the PoE power supply. If the PIDU
is installed instead of the PoE power supply, the test procedures will be
different.
Testing w hen PoE LED s do not illum ina t e correctly
If the DATA & POWER OUT and DATA IN LEDs do not illuminate correctly during the
start-up sequence, test the link end as described in Test flowcharts on page 8-3 and
the detailed test procedures that follow.
Testing a ft e r a light ning st rik e
If the installation has been struck by lightning, proceed as follows:
1 Test the link end as described in Test flowcharts on page 8-3 and the
detailed test procedures that follow.
2 Ensure that the PoE power supply is working and that the resistances
are correct as specified in Test resistance at the PoE end of the drop
cable on page 8-10.
3 If the ODU is not working, power off the ODU and LPU and return them
to Motorola.
4 If the ODU is working but there is suspicion of damage to the LPU, then
refer to

PORT LED is off
When the PoE power supply is connected to the power supply and the AC LED
illuminates, there should be a 45 second delay, following which the PORT LED should
illuminate (green steady).
If the PORT LED is off, proceed as follows:
1 Check that the RJ45 connection from the DATA IN port of the PoE
power supply to the PC is working.
2 If the PC connection is working, remove and examine the cable that
connects the PoE power supply to the LPU or ODU.
3 Check that the resistances are correct as specified in Test resistance at
the PoE end of the drop cable on page 8-10.
4 If this test fails, replace or repair the cable that connects the PoE power
supply to the LPU or ODU.

If the PORT LED is flashing, proceed as follows:
1 Remove and examine the cable that connects the PoE power supply to
the LPU or ODU.
2 Check that the resistances are correct as specified in Test resistance at
the PoE end of the drop cable on page 8-10.
3 Use the LPU (if installed) to check that power is available on the cable
to the ODU. Access the connections by rotating the LPU lid as shown in
Figure 8-3. Slacken the lid nut but do not remove it.
4 Test that test point P1 on the LPU PCB corresponds to pin 1 on the
RJ45. Repeat for points P2 to P8.

To test for Ethernet packet errors, proceed as follows:
1 Log in to the unit and select menu option Statistics.
2 Select Reset Counters at the bottom of the page and wait until the Data
Port Rx Packets counter has reached 1 million.
3 If the counter does not increment or increments too slowly, because for
example the link is newly installed and there is no offered Ethernet
traffic, then abandon this procedure and consider using the procedure
Test ping packet loss on page 8-9.
Test Et he r net pack et e r r ors report ed by m ana ged sw it ch or

Test ping pa cket loss
Using a computer, it is possible to generate and monitor packets lost between the PoE
power supply and the ODU. This can be achieved by executing the Command Prompt
application which is supplied as standard with Windows and Max OS X operating
systems.
To test ping packet loss, proceed as follows:
1 Ensure that the IP address of the computer is configured appropriately for
connection to the ODU under test, and does not clash with the IP addresses
of other devices connected to the network.
2 If the PoE power supply is connected to an Ethernet switch or router then
connect the computer to a spare port, if available.
3 If it is not possible to connect the computer to a spare port of an Ethernet
switch or router, then the PoE power supply will need to be disconnected
from the network in order to execute this test.
CAUTION
The following steps will disrupt network traffic carried by the ODU
under test:
Disconnect the PoE power supply from the network.
Connect the computer directly to the LAN port of the PoE power supply.
4 On the computer, open the Command Prompt application.
5 Send 1000 ping packets of length 1500 bytes. The process will take 1000
seconds, which is approximately 17 minutes.
If the computer is running a Windows operating system, this is achieved by
typing:
ping –n 1000 –l 1500 <ipaddress>
where <ipaddress> is the IP address of the ODU under test.
If the computer is running a MAC operating system, this is achieved by
typing:
ping –c 1000 –s 1492 <ipaddress>
where <ipaddress> is the IP address of the ODU under test.

6 Record how many Ping packets have been lost. This is reported by Command
Prompt on completion of the test.
The test has passed if the number of lost packets is less than 2.
Test resist a nce a t t he PoE e nd of t he drop cable
If the above procedures fail to diagnose the issue, there may be a fault in the wiring of
the drop cable that connects the ODU (or LPU) to the PoE power supply. Perform this
task to test the resistances between the RJ45 pins.
Use the PTP drop cable tester (Figure 8-4) to make testing easier. This can be ordered
from http://www.motorola.com/ptp/support by selecting Order Cable Tester and
completing the order form.
NOTE
The values printed on the PTP drop cable tester do not apply to the PTP 250.
Figure 8 - 4 Drop cable test er ( front and back views)
Unplug the drop cable from the DATA & POWER OUT port of the PoE power supply.
Connect the drop cable tester to the end of the drop cable. Then, perform the tests
described in Table 8-1. Record the results in the Result column, if this is helpful.

Te st ing t he radio link
This section describes how to test the link when there is no radio communication, or
when it is unreliable, or when the data throughput rate is too low. It may be necessary
to test the ODUs at both ends of the link.
N o activit y
If there is no wireless activity, proceed as follows:
1 Select menu option Home and check Wireless Link Status on the System
Summary page.
2 Check that the firmware at each end of the link is the same version.
3 Check Range and Transmit Power.
4 Check Master/Slave Mode for each unit and ensure that one unit is
Master and the other unit is Slave.
5 Check that the link is not obstructed or the ODU misaligned.
6 Use the Channel Status web page at each end of the link to confirm that
there is a quiet wireless channel to use. Refer to Checking channel status
on page 7-19.
7 If there are no faults found in the configuration and there is absolutely no
wireless signal, retry the installation procedure.
8 If this does not work then report a suspected ODU fault to Motorola.

If there is some activity but the link is unreliable or does not achieve the data rates
required, proceed as follows:
1 Use the Channel Status web page to check if a quieter channel is available
and is enabled. Refer to Checking channel status on page 7-19.
2 Use the Diagnostics Plotter to check that reported Link Loss is low
enough to allow the communication rates required. Refer to Using the
diagnostics plotter on page 7-21.
3 Check that the ODU has not become misaligned.
4 Use the Retry Histogram to check the number of retries. An excessive
number of retries (>10%) could indicate a problem. Refer to Checking the
retry histogram on page 7-20.
5 Use the Diagnostics Plotter to check reported Receive Power at either end
of the link. Ensure that this matches the predicted value from
LINKPlanner. Refer to Using the diagnostics plotter on page 7-21.
