Safety
Important safety information
............................................................
.
.
.
.
This section describes important safety guidelines that must be observed by personnel
installing or operating PTP 300 or PTP 500 equipment.
WARNING
To prevent loss of life or physical injury, observe the safety guidelines
in this section.
Power lines
Exercise extreme care when installing antennas near power lines.
Working at heights
Exercise extreme care when working at heights.
Grounding and protective earth
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.

Safety
PIDU Plus
The supplied Power Indoor Plus (PIDU Plus PTP 300/500/600 Series) is used to power
the ODU. Failure to use the Motorola supplied PIDU could result in equipment damage
and will invalidate the safety certification and may cause a safety hazard.
Powering down before servicing
Always power down and unplug the equipment before servicing.
Cable measuring card
A cable measuring card must NEVER be used at the ODU end connected to power
from the PIDU Plus. It must only be used at the bottom of the mast with a multimeter.
This is because the PIDU Plus voltage exceeds the limit allowed in some countries for
safe handling in wet conditions and therefore may create a safety hazard.
Non-Motorola power supply
Safety may be compromised if a different power supply is used than the one supplied
by Motorola as part of the system.
Alternative DC supplies
When using alternative DC supplies (via the PIDU Plus DC in terminals), such as
battery-backed DC power source, the supply MUST comply with the following
requirements:
•
The voltage and polarity is correct and is applied to the correct terminals in the
PIDU Plus.
•
The power source is rated as Safety Extra Low Voltage (SELV).
•
The power source is rated to supply at least 1A 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).

Safety
Primary disconnect device
The main power supply is the primary disconnect device.
External cables
Safety may be compromised if outdoor rated cables are not used for connections that
will be exposed to the weather.
Grounding PTP-SYNC
In order to meet the safety requirements for deployment in Australia and New Zealand
(AS/NZS 60950-1), the PTP-SYNC unit, if deployed, must be grounded to a Protective
Ground in accordance with Local Electrical Regulations.
RF exposure near the antenna
Strong radio frequency (RF) fields will be present close to the antenna when the
transmitter is on. Always mute the transmitter before undertaking maintenance
activities in front of the antenna.
Minimum separation distances
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 4-67.

Important regulatory information
............................................................

Operation of the PTP 300 and PTP 500 Series products involves their use as unlicensed
devices in frequency bands where they are not allowed to cause interference to
licensed services (called primary users of the bands).
Radar avoidance
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 300 and PTP 500 systems provide detect and avoid 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 licence key/region 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.

Regulatory
USA specific information
The USA Federal Communications Commission (FCC) has asked manufacturers to
implement special features to prevent interference to weather radar systems that
operate in the band 5600 MHz to 5650 MHz. These features must be implemented in
all products able to operate outdoors in the band 5470 MHz to 5725 MHz.
Manufacturers must ensure that such radio products cannot be configured to operate
outside of FCC rules; specifically it must not be possible to disable or modify the radar
protection functions that have been demonstrated to the FCC.
In order to comply with these clear FCC requirements for all manufacturers, Motorola
is releasing new versions of PTP 300 and PTP 500 for USA or Canada operation. These
new devices will only be allowed to operate with licence keys/region codes which will
comply with FCC/IC rules.
Other versions of the products will be available for use in the rest of the world, but
these versions will not be supplied to the USA except under strict controls, when they
are needed for export and deployment outside the USA.
Installers must follow this procedure when deploying PTP 300 or PTP 500 links in the
USA or Canada:
•
Check whether either master or slave units are being installed within 35 km of a
TDWR system or have a line of sight propagation path to such a system. This can
be checked by visiting http://spectrumbridge.com/udrs/home.aspx.
•
If a TDWR system is located within 35km or has line of sight propagation to the
PTP device, then the installer must:
o
Register the installation on http://spectrumbridge.com/udrs/home.aspx.
o
Use channel barring to ensure a minimum of 30 MHz separation between
the TDWR frequency and the operating channel frequency of the PTP
system.

Overview
Chapter 1 Product description
Overview
Motorola PTP 300 and PTP 500 Series 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 300 and PTP 500 Series are 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. The system is transparent to higher-level protocols
such as VLANs and Spanning Tree.
Key features
The key features of the PTP 300 and PTP 500 Series include:
•
True non-line-of-sight (NLOS) operation by using a combination of Orthogonal
Frequency Division Multiplexing (OFDM) modulation and Multiple-Input
Multiple-Output (MIMO) techniques.
•
Wireless connections of up to 250 km (155 miles) in near line-of-sight conditions
and up to 100 meters (330 ft) in deep non-line-of-sight conditions.
•
Coexistence with other users of the band using a combination of Spectrum
Management functionality and Antenna beam shape.
•
High link availability, through the use of adaptive modulation techniques that
dynamically reduce the data rate in severe or adverse conditions.
•
High system gain through high sensitivity antennas for improved signal recovery.
•
A radio system that operates using ultra-fast digital signal processors and is
controlled by updateable firmware.
•
A built-in web server for advanced management capabilities including detailed
radio signal diagnosis.
•
A range of security features to prevent unauthorized access to data. Optional AES
encryption for data transmitted over the wireless, with 128-bit or 256-bit
encryption keys. SNMPv3 with optional AES privacy and SHA1 authentication.

PTP 300 and PTP 500 Series User Guide
Overview
Benefit of the 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.
Similarity to 802.11a devices
The products are not 802.11a devices. Although similar, they use different encoding
and radio transmission systems from 802.11a. In areas where 802.11a systems are
operating, the products will detect the 802.11a radio signals and choose a clear
channel away from any interference.
Avoiding interference from nearby devices
At initialization, the products monitor the available frequency channels to find a
channel that is clear of interference. In operation, the products continuously monitor
the spectrum to ensure it is operating on the cleanest channel.
Typical deployment
The PTP 300 or PTP 500 Series Bridge consists of an identical pair of units deployed
one at each end of the link. The radio link operates on a single frequency channel in
each direction using Time Division Duplex (TDD). One unit is deployed 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. An example application is an
enterprise that has a requirement to connect together the Local Area Network (LAN)
of two or more buildings as shown in Figure 1-1.

Cabling and lightning protection
Cabling and lightning protection
The cabling and lightning protection components of a PTP 300 or PTP 500 installation
are:
•
Outdoor drop cable
•
Indoor CAT5e cable
•
Grounding cables
•
Lightning protection units
PTP and lightning protection
The PIDU Plus meets the low level static discharge specifications identified in EMC
immunity compliance on page 4-58 but does not provide lightning or surge
suppression.
The amount of lightning protection is dependent on regulatory requirements and the
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.
CAUTION
The products are not designed to survive direct lightning strikes. For this
reason the units should not be installed as the highest point in a localized
area. See Grounding and lightning protection on page 2-14.
Outdoor 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 (if installed),
GPS receiver (if installed) and the ODU port of the PIDU Plus.
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. See Cable and connector specifications on
page 4-17.

Cabling and lightning protection
Chapter 1 Product description
Indoor connections
The CAT5e cable that connects the PIDU Plus to the network equipment must meet the
screening requirements specified in Cable and connector specifications on page 4-17.
CAUTION
The connected network equipment must feature screened RJ45
connectors and must be connected to ground, otherwise the PIDU Plus will
not be grounded, and this may increase the levels of unwanted radiation
from the ODU - PIDU Plus cables.
NOTE
The ODU network connection implements automatic MDI/MDI-X sensing and
pair swapping, allowing connection to networking equipment that requires
cross-over cables (MDI-X networks) or straight-through cables (MDI
Networks).
Cable grounding kits
Drop cables must be grounded at the points specified in Grounding and lightning
protection on page 2-14. One cable grounding kit (Figure 1-12) is required for each
drop cable grounding point.

PTP-SYNC unit
PTP-SYNC unit description
The PTP-SYNC unit (Figure 1-14) is an optional component for the PTP 500 Series. It is
required when TDD synchronization is implemented using PTP-SYNC. It measures the
difference between the TDD frame timing and a 1 Hz timing reference, and signals this
time difference to the ODU.
For more information on this feature, refer to TDD synchronization on page 1-30.
The PTP-SYNC is a compact indoor unit mounted on a wall or a shelf or (using an
optional rack mounting adaptor) in a standard 19 inch rack. It is powered using
standard power-over-Ethernet from the PIDU Plus. One PTP-SYNC unit is required for
each synchronized link.

Time division duplexing
TDD cycle
PTP 300 and PTP 500 series links operate using Time Division Duplexing (TDD). They
use a TDD cycle in which the ODUs alternately transmit and receive TDD bursts. The
TDD cycle is illustrated in Figure 1-16. The steps in the cycle are as follows:
1. The TDD master transmits a burst to the TDD slave.
2. A delay occurs as the master-slave burst propagates over the link.
3. The slave receives the burst from the master.
4. The slave transmits a burst to the master.
5. A delay occurs as the slave-master burst propagates over the link.
6. The master receives the burst from the slave.
7. The master transmits the next burst to the slave.
TDD frame parameters
The TDD burst duration varies depending on the following:
•
Channel bandwidth
•
Link range
•
Link optimization mode
•
Link symmetry
•
Offered traffic loading.
The TDD frame duration varies depending on the following:
•
TDD burst duration master-slave.
•
TDD burst duration slave-master.
•
Link range.
The propagation delay in Step 2 is necessarily equal to the propagation delay in Step
5, and is determined solely by the link range. There will be added delays between rx
and tx on the master and slave to minimise interference.

Channel selection
The PTP 300 and PTP 500 Series links are capable of transmitting and receiving on the
same channel or on different channels. In other words, the slave-master direction may
use a different channel from the master-slave direction. Independent selection of
transmit and receive frequencies can be useful in planned networks or for countering
interference.
When links operate in radar avoidance regions, each unit must monitor its transmit
channel for the presence of radar signals, and thus transmit and receive channels are
always identical.

Link mode optimization
Link mode optimization allows the link to be optimized according to the type of traffic
that will be bridged. The link supports two modes, IP Traffic and TDM Traffic.
IP traffic
IP Traffic mode is optimized to provide the maximum possible link capacity. IP Traffic
mode is an appropriate choice where applications in the bridged networks provide
some measure of reliable transmission, and where very low latency is not critical. IP
mode supports both fixed and adaptive link symmetry (see Link symmetry on page 121).
TDM traffic
TDM Traffic mode is optimized to provide the lowest possible latency. TDM Traffic
mode additionally implements a more conservative approach to adaptive modulation,
leading to lower error rates in fading channels at the expense of slightly lower link
capacity. TDM Traffic mode is an appropriate choice for delay intolerant data without
reliable transmission (for example voice over IP data). TDM mode is selected
automatically when Telecom interfaces are enabled.
Link symmetry
The PTP 300 and PTP 500 Series provide four configuration options for apportioning
the available capacity between the two link directions.
•
Symmetric: The Master and Slave have equal capacity. The system achieves this
by allocating an equal Burst Duration for the Master and the Slave.
•
3:1 The capacity in the direction Master to Slave is three times that of the
direction Slave to Master. The system series achieves this by setting the Burst
Duration of the Master to three times that of the Slave.
•
1:3 The capacity in the direction Slave to Master is three times that of the
direction Master to Slave. The system achieves this by setting the Burst Duration
of the Slave to three times that of the Master.
NOTE
The 3:1 and 1:3 modes are not available when TDD synchronization is
enabled or when 5 MHz bandwidth is selected.

Chapter 1 Product description
Adaptive: The capacity allocated to a given link direction is dependant on the
offered level of network traffic in both link directions. If the level of offered
traffic in both directions is equally high or equally low, the system will allocate
equal capacity to both directions. If however the offered level of traffic is greater
in one direction, it is allocated a greater proportion of the overall link capacity.
The system achieves this by increasing (or decreasing) the duration of the
Transmit Burst in a given link direction as the offered level of network traffic
increases (or decreases) in this same direction. This is done independently for
the two directions.
NOTE
Adaptive mode is not available in the following configurations :
o
When link mode optimization is set to TDM Traffic see Link mode
optimization on page 1-21).
o
When TDD synchronization is enabled.
o
In regions where radar avoidance is operational (see Radar avoidance on
page 1-27).

Non Line Of Sight (NLOS) and Line Of Sight (LOS)
PTP 300
The PTP 300 Series Bridge is designed to operate by default in both Non Line Of Sight
(NLOS) and Line Of Sight (LOS) environments. However, the PTP 300 web interface
includes a Line Of Sight mode control. When this control is enabled, the bridge can
operate at higher data throughput rates over a short unobstructed path.
LOS mode is available only where license key enables the capability, the mode is
enabled in the Installation Wizard, and the link range is less than 10 km (6.2 miles). A
PTP 300 bridge operating in LOS mode has the same throughput capacity as a PTP
500 Lite bridge.
PTP 500
The PTP 500 Series Bridge is designed to operate in both Non Line Of Sight (NLOS)
and Line Of Sight (LOS) environments. The LOS mode feature is not available in the

Wireless operation
OFDM and channel bandwidth
The PTP 300 and PTP 500 Series transmit using Orthogonal Frequency Division
Multiplexing (OFDM). This wideband signal consists of many equally spaced subcarriers. 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. OFDM
works exceptionally well over a Non-Line-of-Sight (NLoS) channel.
The channel bandwidth of the OFDM signal is configurable to one of three values:
5 MHz, 10 MHz and 15 MHz. Higher bandwidths provide greater link capacity at the
expense of using more spectrum. Systems configured for a narrower channel
bandwidth provide better receiver sensitivity and can also be an appropriate choice in
deployments where the amount of free spectrum is limited.
Each channel is offset in center frequency from its neighboring channel by 5 MHz.
NOTE
The Channel Bandwidth must be configured to the same value at both ends
of the link.
Spectrum management
The spectrum management feature of the PTP 300 and PTP 500 Series 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.
Spectrum management measurements
The system performs two mean signal measurements per TDD cycle, per channel. This
mean measurement represents the mean received signal power for the
40 microseconds measurement period.
The Spectrum Management algorithm collects measurements equally from all
channels. This process is called the Channel Availability Check (hereafter referred to
by the acronym CAC). The CAC uses a round-robin channel selection process to collect
an equal amount of measurements from each channel. The CAC measurement process
is not altered by the channel barring process. Measurements are still collected for all
channels irrespective of the number of barred channels.

Chapter 1 Product description
Measurement analysis
Spectrum Management uses statistical analysis to process the received peak and mean
measurement. The statistical analysis is based on a fixed, one minute, measurement
quantization period. Spectrum Management collects data for the specified
quantization period and only at the end of the period is the statistical analysis
performed. The analysis produces three key metrics for each channel:
•
Peak of Means
•
99.9% Percentile of the Means
•
Mean of Means
These metrics are defined in Interpreting the spectrum management plots on page 725.
Statistical summary
The display of statistical measurement on the spectrum management page always
shows a statistical summary of all channel measurement. The statistical summary is
controlled by the Statistics Window attribute. This attribute defaults to a value of
twenty minutes, which means that the mean and percentile values displayed for each
channel are calculated over the 20 minute period. All channel decisions are made
using the values computed over the statistics window period.
Spectrum management in fixed frequency mode
The transmit and receive frequencies can be fixed in a PTP 300 or PTP 500 wireless
link. Once fixed frequency mode is configured, the spectrum management software
will not attempt to move the wireless link to a channel with lower co-channel and
adjacent-channel interference. Therefore this mode of operation is only recommended
for deployments where the installer has a good understanding of the prevailing
interference environment (see Step 2: Wireless configuration on page 6-31). Care must
also be taken to ensure that the frequency allocations at each end of the link are
compatible.
Fixed frequency mode is not available in regions where radar detection is required by
the regulations.

Adaptive modulation
The PTP 300 and PTP 500 Series can transport data over the wireless link using a
number of different modulation modes ranging from 64QAM 0.83 to BPSK 0.50. For a
given channel bandwidth and TDD frame structure, 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 such as 64QAM 0.83 will transport data at a much higher rate than the
less complex modulation modes, the receiver requires a much higher signal to noise
ratio.
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. This is one of a number of features which allows the system to
operate in challenging none line of sight radio channels.
Specifications of capacity for all channel bandwidths, modulation modes and
configurations are provided in Data throughput capacity on page 4-80.
Specifications of receive level thresholds for each modulation mode (assuming no
interference) are provided in the various system threshold tables in Chapter 4
Reference information.
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.
MIMO
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 over a non-line-of-sight path.

Chapter 1 Product description
The PTP 300 and PTP 500 transmit 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 non- line
of sight radio channels.
The two modes have been implemented by the introduction of two sets of modulation
modes. The lower order modulations (BPSK 0.50 up to QPSK 0.50) are only available
as single payload modes. Each of the higher order modulations (QPSK 0.75 to
64QAM 0.83) are available in single payload mode and dual payload mode. The
switching between modes is automatically controlled by the adaptive modulation
feature described in Adaptive modulation on page 1-25.
NOTE
The system automatically chooses between dual and single payload to try to
increase the capacity of a link. However the user may choose 'single payload
only' at installation time, forcing this more robust option.
Intelligent dynamic frequency selection
The PTP 300 and PTP 500 Series use an interference mitigation technique known as
Intelligent Dynamic Frequency Selection (i-DFS). Both the Master and Slave
continually monitor for interference on all channels and then select the best frequency
of operation. This is a dynamic process where the system can continually move
channels in response to changes in interference. Two modes of operation are available:
•
The first mode is where the two link directions are forced to select the same
frequency. This is determined by the Master.
•
The second mode is where the frequency of operation can be determined
independently for each direction. This uses the CAC measurements. It enables
the system to operate successfully in areas where other radio equipments are
operating within the same band. It is not permitted in radar regions.

PTP 300 and PTP 500 Series User Guide
Wireless operation
Radar avoidance
In regions where protection of radars is part of the local regulations, the PTP 300 and
PTP 500 must detect interference from radar-like systems and avoid co-channel
operation with these systems.
To meet this requirement, the PTP 300 and PTP 500 implement the following features:
•
The equipment 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 for radar interference before making the channel an
available channel.
•
This compulsory channel scan will mean that there is at least 60 seconds service
outage every time radar is detected and that the installation time is extended by
at least 60 seconds even if there is found to be no radar on the channel
•
When operating on a channel, the spectrum management algorithm implements a
radar detection function 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 thirty minutes after the impulsive
interference pulse was detected.
•
After the thirty 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 a uniform 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 same
effect of spreading the load across the spectrum).
•
The FCC does allow channels to be barred if there is actually interference on
them.
NOTE
Fixed frequency allocation is not recommended in radar avoidance regions,
as any radar detection would cause a system outage of at least 30 minutes.

Security
The PTP 300 and PTP 500 Series support optional encryption for data transmitted over
the wireless link. The encryption algorithm used is the Advanced Encryption Standard
(AES) with 128-bit and 256-bit key size. AES is a symmetric encryption algorithm
approved by U.S. Government organizations (and others) to protect sensitive
information. The AES implementation in PTP 300 and PTP 500 is approved to FIPS197.
Encryption is enabled through the purchase of an upgrade.
Region codes
Some aspects of wireless operation are controlled, enforced or restricted according to
a region code. Region codes represent individual countries (for example Denmark) or
regulatory regions (for example FCC or ETSI).
Region codes affect the following aspects of wireless operation:
•
Maximum transmit power
•
Radar avoidance
•
Transmit power reduction in edge channels
•
Frequency range
•
Channel plan
A region code is encoded in the license key. The region code can be changed by
generating and entering a new license key.
NOTE
Some units are supplied with two alternative license keys for different region
codes, one of which is factory configured.
CAUTION
To avoid possible enforcement action by the country regulator, always
operate links in accordance with local regulations.

PTP networks
Using Intelligent Dynamic Frequency Selection
The Intelligent Dynamic Frequency Selection (i-DFS) feature allows a PTP 300 or PTP
500 unit to select wireless channels for a lower level of radio frequency (RF)
interference. This approach is appropriate where the network consists of a small
number of PTP links, or where the RF interference is predominantly from equipment
belonging to other operators.
Using frequency 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

Chapter 1 Product description
Synchronized networks
TDD synchronization can be used to relax constraints on the frequency planning of
PTP 500 networks. Synchronization has the following benefits:
•
Allows tighter frequency re-use, and thus wider channel bandwidth.
•
Allows more convenient collocation of units on a single mast.
•
Allows use of smaller or lower performance antennas.
•
Reduces inference, resulting in use of more efficient modulation modes.
NOTE
TDD synchronization is not supported in the PTP 300 Series.
In a correctly designed synchronised network, all links are configured with the same
TDD frame duration, and the TDD frame contains guard periods longer than the
propagation delay between the most distant interfering units.
Each synchronized unit is assigned to one of two phases. A master ODU can be
assigned to either phase. A slave ODU must be assigned to a different phase from the
associated master ODU. The phase is set by suitable configuration of TDD Frame
Offset.
TDD synchronization eliminates RF interference between units in the same phase. This
means that frequency planning in a synchronized network is concerned only with
interference between units in different phases. Frequency planning is still necessary,
but the number of potential interference paths to be considered is halved. Frequency
planning in a synchronized TDD network has approximately the same level of
complexity as frequency planning in a Frequency Division Duplex (FDD) network.
TDD synchronization
Additional hardware
To synchronize PTP 500 links, one PTP-SYNC unit is required for each master ODU.
The PTP-SYNC unit is connected in line in the drop cable between the PIDU Plus and
the ODU, and is collocated with the PIDU Plus.
NOTE
TDD synchronization is not supported in the PTP 300 Series.

Timing references for use with PTP-SYNC
PTP-SYNC requires an external timing reference in all but the simplest networks. Up
to ten PTP-SYNCs can be connected in a chain to share the timing signal from one
timing reference. In the majority of applications, one reference is required for each
site that contains master ODUs.
The timing reference can be from any timing system that provides a 1 Hz signal,
accurately synchronized in frequency and phase with a network-wide master timing
reference. GPS timing receivers are a very practical way of obtaining a suitable
reference. The PTP-SYNC is compatible with the following GPS timing receivers:
•
Trimble Acutime™ Gold GPS receiver
In simple networks where all master ODUs are at a single site, the external reference
can be omitted. In this case, one ODU acts as a reference for other collocated units.
Configuring the TDD frame
In synchronized operation, frame duration and burst duration must be configured
directly in the web-based management interface. Frame duration must be identical
across all links in a synchronized network.
PTP LINKPlanner provides a capability for computing suitable frame parameters in a
synchronized network. Please refer to the PTP LINKPlanner User Guide for guidance
on configuring TDD synchronization.
Link symmetry is always 1:1 in synchronized networks.
Link capacity in synchronized networks
The TDD frame duration is extended in synchronized networks to allow for the
propagation delay of the longest link in the network and to incorporate additional
guard periods. These guard periods protect against delayed interference from distant
units in the same network.
The longer frame duration results in slightly lower link capacity than for an equivalent
non-synchronized link with the same channel bandwidth and modulation mode.
However, TDD synchronization also reduces interference, and this may allow operation
in higher modulation modes. The benefit of operating in a higher modulation mode
normally outweighs the penalty of the slightly longer TDD frame.

Advantages of PTP-SYNC
The advantages of PTP-SYNC over alternative technologies are:
•
PTP-SYNC does not require individual GPS receivers, nor must they be located
close to the ODUs. This reduces the complexity and the cost of the installation on
the mast.
•
The GPS receiver can be located anywhere with a clear view of the sky, offering
additional flexibility in the installation.
•
The PTP-SYNC solution is compatible with standard 1 Hz interfaces, allowing an
operator to take advantage of alternative timing references that may be already
present at the site.
•
The recommended GPS receiver continues to provide accurate timing even after
the number of received satellites has dropped down to one, leading to
significantly better availability of the reference signal.
•
The PTP-SYNC offers the possibility of creating synchronized single-hub networks
where no GPS receiver is required.

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 two control protocols
The PTP 300 and PTP 500 Series are transparent to layer two control protocols (L2CP)
including:
•
Spanning tree protocol (STP), rapid spanning tree protocol (RSTP)
•
Multiple spanning tree protocol (MSTP)

Ethernet bridging
Chapter 1 Product description
Quality of service for bridged Ethernet traffic
The PTP 300 and PTP 500 Series support eight traffic classes for Ethernet frames
queued for transmission over the wireless link. Ethernet frames are classified by
inspection of the Ethernet priority code point in the outermost VLAN tag.
The system provides a configurable mapping between Ethernet priority and traffic
class, together with a simple way to restore a default mapping based on the
recommended default in IEEE 802.1Q-2005. Untagged frames can be classified into
any one of the eight classes.
Scheduling for transmission over the wireless link is by strict priority. In other words,
a frame at the head of a given queue is transmitted only when all higher priority
queues are empty.
Fragmentation
The PTP 300 and PTP 500 Series minimize latency and jitter for high-priority Ethernet
traffic by fragmenting Ethernet frames before transmission over the wireless link. The
fragment size is selected automatically according to channel bandwidth and
modulation mode of the wireless link. Fragments are reassembled on reception, and
incomplete Ethernet frames are discarded.
Management network
IP interface
The PTP 300 and PTP 500 ODU contains an embedded management agent with a
single IP interface. Network management communication is exclusively based on IP
and associated higher layer transport and application protocols. The default IP address
of the management agent is 169.254.1.1 in the master ODU and 169.254.1.2 in the
slave ODU. The products do not require use of supplementary serial interfaces.
MAC address
The management agent end-station MAC address is recorded on the enclosure. The
MAC address is not configurable by the user.
VLAN membership
The management agent can be configured to transmit and receive either untagged,
priority-tagged, C-tagged (IEEE 802.1Q) or S-tagged (IEEE 801.ad) frames. S-tagged
frames must be single tagged, in other words, an S-tag with no encapsulated C-tag.
The VLAN ID can be 0 (priority tagged) or in the range 1 to 4094.

In-band management
In the in-band management mode, the management agent can be reached from the
Ethernet port at the local ODU, and (assuming that the wireless link is established) the
Ethernet port at the remote ODU.
Management frames in the customer network are processed by the management agent
if (a) destination MAC address in the frame matches the CMU MAC address, and (b)
the VLAN ID in the frame matches the VLAN configuration of the management agent.
If Local Packet Filtering is enabled, unicast frames forwarded to the management
agent are filtered, that is, not forwarded in the customer network.
In-band quality of service
Frames generated within the management agent may be assigned a configured
Ethernet priority. Management frames are multiplexed with customer frames of the
same priority for transmission at the wireless port.
Source address learning
If Local Packet Filtering is enabled, the system learns the location of end stations from
the source addresses in received management frames. The agent filters transmitted
management frames to ensure that the frame is transmitted at the Ethernet port, or
over the wireless link as appropriate. If the end station address is unknown, then
management traffic is transmitted at the Ethernet port and over the wireless link.
Wireless link down alert
The PTP 300 and PTP 500 Series provide an optional indication of failure of the
wireless link by means of a brief disconnection of the data port. The Wireless link
down alert can be used to trigger protection switching by Spanning Tree Protocol
(STP) or Ethernet Automatic Protection Switching (EAPS) in a redundant network.
Back-to-back links
PTP 300 and PTP 500 will not operate correctly if a direct cabled connection is made
between two PIDUs. Where two or more links are deployed in a chain, always use an
Ethernet switch or router to interconnect the links at the relay points.

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 circuitmode 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

Telecoms circuits
Chapter 1 Product description
Telecoms circuits
The PTP 300 and PTP 500 provide native support for one E1 link, or one T1 link. The
link relays unstructured E1 or T1 data and provides accurate timing transfer.
Lowest telecoms modulation mode
In narrow channel bandwidth and lower modulation modes, the link may have
insufficient capacity to relay the E1/T1 payload; in this case, the wireless link
continues to carry timing information in order to maintain accurate clock
synchronization. The relay of telecoms data resumes automatically when the link
reaches a suitable modulation mode.
Links that are able to operate consistently in a high modulation mode can take
advantage of lower link latency. This option is configured by setting the "Lowest
Telecoms Modulation Mode" during installation. Appropriate settings for this control
may be determined by using the PTP LINKPlanner tool. The reduction in latency is
achieved by disabling the relay of telecoms data in lower modulation modes, and this
necessarily results in somewhat lower availability for the telecoms circuit. The loss of
availability can be estimated using the PTP LINKPlanner.
The unit will override the user setting of Lowest Telecoms Modulation Mode if the
selected mode has insufficient capacity to carry the telecoms data, or if the mode
demands very high latency and requires more buffering than the link can provide.
When the effective mode differs for Single and Dual Payload operation two modes will
be displayed: "Lowest Dual Payload Modulation Mode" and "Lowest Single Payload
Modulation Mode".

Fixed frequency operation
In a PTP 300 or PTP 500 link, data errors may occur during channel changes on an
operational link. It may be appropriate to minimize channel-change-related errors in a
link carrying Telecoms traffic by preventing channel changes initiated by i-DFS. This
can be achieved by barring all channels except one in the Spectrum Management
page, or alternately by selecting Fixed Frequency mode. These steps unavoidably
disable interference avoidance mechanisms, and should not be taken if the risk of
errors due to interference is more severe than the risk due to channel changes.
Fixed frequency operation is not available when radar detection requirements exist in
the frequency band. Channel barring is allowed in radar regions, but it is unwise to
bar all channels except one, as any radar signals detected on that channel will drop
the link for up to 30 minutes.

SNMPv3 security
SNMP Engine ID
PTP 300 and PTP 500 support three different formats for SNMP Engine ID:
•
MAC address
•
IP address
•
Configurable text string
SNMPv3 security configuration is re-initialized when the SNMP Engine ID is changed.
User-based security model
PTP 300 and PTP 500 support the SNMPv3 user-based security model (USM) for up to
10 users, with MD5, SHA-1, DES and (subject to the license key) AES protocols in the
following combinations:
•
No authentication, no privacy,
•
MD5, no privacy,
•
SHA-1, no privacy,
•
MD5, DES,
•
SHA-1, DES,
•
MD5, AES,
•
SHA-1, AES.
Use of AES privacy requires the AES upgrade described in AES license on page 1-46.
The ODU will allow the creation of users configured with AES privacy protocol,
regardless of license key. However, a user configured to use AES privacy protocol will
not be able to transmit and receive encrypted messages unless the license key enables
the AES capability.
View-based access control model
PTP 300 and PTP 500 support the SNMPv3 view-based access control model (VACM)
with a single context. The context name is the empty string. The context table is readonly, and cannot be modified by users.

Access to critical security parameters
The SNMPv3 management interface does not provide access to critical security
parameters (CSPs). It is not possible to read or modify AES keys used to encrypt data
transmitted at the wireless interface.
MIB-based management of SNMPv3 security
PTP 300 and PTP 500 support a standards-based approach to configuring SNMPv3
users and views through the SNMP MIB. This approach provides maximum flexibility
in terms of defining views and security levels appropriate for different types of user.
The system provides a default SNMPv3 configuration. This initial configuration is not
secure, but it provides the means by which a secure configuration can be created
using SNMPv3.
The secure configuration should be configured in a controlled environment to prevent
disclosure of the initial security keys necessarily sent as plaintext, or sent as encrypted
data using a predictable key. The initial security information should not be configured
over an insecure network.
The default configuration is restored when any of the following occurs:
•
All ODU configuration data is erased.
•
All SNMP users are deleted using the SNMP management interface.
•
The SNMP Engine ID Format has been changed.
•
The SNMP Engine ID Format is IP Address AND the IP Address has been
changed.
•
The SNMP Engine ID Format is Text String AND the text string has been
changed.
•
The SNMP Engine ID Format is MAC Address AND configuration has been
restored using a file saved from a different unit.
•
SNMPv3 Security Management is changed from web-based to MIB-based.
The default user configuration is specified in SNMPv3 default configuration (MIBbased) on page 4-55.
The system creates the initial user and template users with localized authentication
and privacy keys derived from the passphrase string 123456789. Authentication keys
for the templates users are fixed and cannot be changed. Any or all of the template
users can be deleted.
The default user initial is created with a view of the entire MIB, requiring
authentication for SET operations. There is no access for template users.
phn-1115_006v000
Sep 2010

System management
Chapter 1 Product description
NOTE
VACM grants access for requests sent with more than the configured
security level.
The default user initial will have read/write access to the whole of the MIB. This is
described in further detail in View-based access control model on page 1-42. The
template users have no access to the MIB in the default configuration. User initial will
normally be used to create one or more additional users with secret authentication and
privacy keys, and with appropriate access to the whole of the MIB or to particular
views of the MIB according to the operator’s security policy. New users must be
created by cloning template users. The user initial may then be deleted to prevent
access using the well-known user name and keys. Alternatively, the keys associated
with initial may be set to some new secret value.
Web-based management of SNMPv3 security
PTP 300 and PTP 500 support an alternative, web-based approach for configuring
SNMPv3 security. In this case, the web-based interface allows users to specify
SNMPv3 users, security levels, privacy and authentication protocols, and passphrases.
Web-based management will be effective for many network applications, but the
capabilities supported are somewhat less flexible than those supported using the MIBbased security management.
Selection of web-based management for SNMPv3 security disables the MIB-based
security management.
Web-based management of SNMPv3 security allows for two security roles:
•
Read Only
•
System Administrator
Read Only and System Administrator users are associated with fixed views allowing
access to the whole of the MIB, excluding the objects associated with SNMPv3
security. System Administrators have read/write access as defined in the standard and
proprietary MIBs.
Web-based management of SNMPv3 security allows an operator to define the security
levels and protocols for each of the security roles; all users with the same role share a
common selection of security level and protocols.

•

•
SNMPv3 Security Management is changed from MIB-based to web-based.
Additionally, all SNMP user accounts are disabled when the authentication protocol,
the privacy protocol, or the security level is changed.
Downgrade of the license key
A possible lockout condition exists if a user downgrades the license key so as to
disable the AES capability when SNMPv3 users are configured with AES privacy and
VACM is configured to require privacy. In this case, recovery is by either (a) restoring
the correct license key, or (b) using recovery mode to erase all configuration and
entering new configuration.
Option (b) will cause default users and access configuration to be re-created.

Chapter 1 Product description
AES license
PTP 300 and PTP 500 provide optional encryption using the Advanced Encryption
Standard (AES). Encryption is not available in the standard system.
AES upgrades are supplied as an access key purchased from your Motorola Point-toPoint distributor or solutions provider. The access key authorizes AES operation for
one ODU. Two access keys are needed to operate AES on a link. The upgrade is
applied by entering an access key together with the MAC address of the target ODU
into the PTP License Key Generator web page, which may be accessed from
http://www.motorola.com/ptp/support.
The License Key Generator creates a new license key that is delivered by email. The
license key must be installed on the ODU. When the license key is installed, the ODU
must be rebooted before AES can be enabled. Once applied, the AES upgrade is bound
to a single ODU and is not transferrable.
AES encryption may be used in the following ways:
•
At the wireless port to encrypt data transmitted over the wireless link.
•
At the SNMP management interface in the SNMPv3 mode.
Two levels of encryption are available to purchase:
•
128-bit: This allows an operator to encrypt all traffic sent over the wireless link
using 128-bit encryption.
•
256-bit: This allows an operator to encrypt traffic using either 128-bit or 256-bit
encryption.
Encryption must be configured with the same size key in each direction.
AES encryption at the wireless port is based on pre-shared keys. An identical key must
be entered at each end of the link.
AES encryption for SNMPv3 is always based on a 128-bit key, regardless of level
enabled in the license key.

Capacity upgrades
Capacity upgrades are supplied as an access key purchased from your Motorola Pointto-Point distributor or solutions provider. The upgrade is applied by entering an access
key together with the MAC address of the target ODU into the PTP License Key
Generator web page, which may be accessed from
http://www.motorola.com/ptp/support.
The License Key Generator creates a new license key delivered by email. The license
key must be installed on the ODU as described in reference to Task 4: Installing
license keys on page 6-14. Once applied, the capacity upgrade is bound to a single
ODU and is not transferrable.
Software upgrade
The management agent supports application software upgrade using either the webbased interface or the SNMP interface.
PTP 300 and PTP 500 software images are digitally signed, and the ODU will accept
only images that contain a valid Motorola PTP digital signature. The ODU always
requires a reboot to complete a software upgrade.
NOTE
Obtain the application software and this user guide from the support website
BEFORE warranty expires.
NOTE
ODU software version must be the same at both ends of the link. Limited
operation may sometimes be possible with dissimilar software versions, but
such operation is not supported by Motorola.
The management process for software upgrade is described in detail in Task 5:

Recovery mode
The PTP 300 and PTP 500 recovery mode provides a means to recover from serious
configuration errors including lost or forgotten passwords and unknown IP addresses.
Recovery mode also allows new main application software to be loaded even when the
integrity of the existing main application software image has been compromised. The
most likely cause of an integrity problem with the installed main application software
is where the power supply has been interrupted during an earlier software upgrade.
The ODU operates in recovery mode in the following circumstances:
•
When a checksum error occurs for the main application software image.
•
When the PIDU Plus recovery button is pressed at the same time as the ODU is
rebooted or power cycled.
Recovery mode options
Options in recovery mode are as follows:
•
Load new main application software.
•
Reset all configuration data to factory default. This option resets IP and Ethernet
configuration.
•
Reset IP and Ethernet configuration to factory default.
•
Reboot with existing software and configuration.
NOTE
If recovery mode has been entered because of a checksum error, by default
the ODU will reboot with existing software and configuration, following a 30
second wait.
The recovery software image is installed during manufacture of the ODU and cannot
be upgraded by operators.
For detailed instructions on using the recovery mode, see Using recovery mode on
page 7-53.

Chapter 2 Planning considerations
Spectrum planning
Each frequency variant has specific regulatory restrictions that affect frequency range,
radar avoidance and channel bandwidth usage.
Conformance to regulations
Ensure the link is configured to conform to local regulatory requirements by installing
license keys for the correct region code.
CAUTION
For the connectorized model, when using external antennas of higher gain
than the appropriate integrated antenna, the regulations may require the
maximum Tx power to be reduced. To ensure that regulatory requirements
are met for connectorized installations, refer to Regulatory issues with
connectorized units on page 4-62.
The license and region codes for each frequency variant are listed in Licenses and
region codes on page 4-32.
Frequency selection
Choose a method of frequency selection. The choice depends upon whether or not the
region mandates DFS (radar detection).
Regions without mandatory radar detection
In regions that do not mandate DFS, choose ‘i-DFS’ or ‘Fixed Frequency’:
•
Intelligent Dynamic Frequency Selection (i-DFS): In this mode, the unit
continually continually monitors the spectrum looking for the channel with the
lowest level of interference. Statistical techniques are used to select the most
appropriate transmit and receive channels. The unit can be configured such that
it operates in i-DFS mode, but does not operate on selected channels. This allows
a frequency plan to be implemented in cases where multiple links are installed in
close proximity.
phn-1115_006v000
2-2
Sep 2010
PTP 300 and PTP 500 Series User Guide
•
Spectrum planning
Fixed Frequency: In this mode, the unit must be configured with a single fixed
transmit frequency and a single fixed receive frequency. These may set to the
same value or to different values. This mode should only be considered in
exceptional circumstances, for example where it is known that are no sources of
interference on the selected channels.
Regions with mandatory radar detection
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.
NOTE
The PTP 300 and PTP 500 fully conform to regional regulatory requirements
for radar avoidance.
In DFS regions, choose ‘DFS’ or ‘DFS with i-DFS’:
•
Dynamic Frequency Selection (DFS): Once a channel is selected, the unit will
only attempt to find an alternative channel if radar activity has been detected on
the operating channel.
•
DFS with i-DFS: In addition to switching channels on detection of radar, the unit
will also switch to a channel which has a significantly lower level of interference
than the current channel of operation. Before radiating on the newly selected
channel, the unit must again ensure that there is no radar activity on the new
channel for a period of 60 seconds. This mode therefore provides the benefit of
switching to a channel with lower interference but at the expense of an an outage
of approximately 60 to 120 seconds. For this reason, the threshold for switching
channels is greater than when i-DFS is operating in a non-radar region.

Chapter 2 Planning considerations
NOTE
Radar avoidance requirements in the 5.4 GHz band are defined as follows:
o
For the EU: in specification EN 301-893 version V1.5.1.
o
For the US: in the specification FCC part 15.407 plus the later
requirements covered in Important Regulatory Inofrmation in this
User Guide.
o
For Canada: in the specification RSS210 Annex 9 (Issue 7).
Radar avoidance at 5.8 GHz is applicable to EU operation (not FCC/IC) and
the requirements are defined in EN 302 502.
Available spectrum
The available spectrum for operation depends on the region. When configured with the
appropriate license key, the unit will only allow operation on those channels which are
permitted by the regulations.
Of particular note, is that certain regulations have allocated certain channels as
unavailable for use:
•
ETSI has allocated part of the 5.4 GHz band to weather radar.
•
UK and some other European countries have allocated part of the 5.8 GHz band
to Road Transport and Traffic Telematics (RTTT) systems.
For details of these restrictions, refer to Licenses and region codes on page 4-32.
Where regulatory restrictions apply to certain channels, these channels are barred
automatically by the use of the correct licence key and region code. 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 license key installed for this region, the PTP
500 will not operate on channels within this band.
The number and identity of channels barred by the licence key and region code is
dependent on the channel bandwidth and channel raster selected.
Barred channels are indicated by a ‘No Entry’ symbol displayed on the Spectrum
Management web page, see Spectrum management in radar avoidance mode on page
7-29.

Avoidance of weather radars (USA only)
To comply with FCC rules, units which are installed within 35 km of a Terminal
Doppler Weather Radar (TDWR) system (or have a line of sight propagation path to
such a system) must be configured to avoid any frequency within +30 MHz or
–30 MHz of the frequency of the TDWR device.
When planning a link in the USA, visit http://spectrumbridge.com/udrs/home.aspx,
enter the location of the planned link and search for TDWR radars. If the search result
lists one or more TDWR radars within 35 km (22 miles), perform the following tasks:
•
Register the installation on http://spectrumbridge.com/udrs/home.aspx.
•
Make a list of channel center frequencies that must be barred, that is, those
falling within +30 MHz or –30 MHz of the frequency of the TDWR radars.
CAUTION
To comply with FCC rules, the affected channels must be barred during
staging, before the units are allowed to radiate on site, as described in
Chapter 6 Configuration and alignment.
Channel bandwidth
Select the required channel bandwidth for the link.
The channel bandwidth may be set to 5 MHz, 10 MHz or 15 MHz. The wider the
channel bandwidth, the greater the capacity.
As narrower channel bandwidths take up less spectrum, selecting a narrow channel
bandwidth may be a better choice when operating in locations where the spectrum is
very busy.
NOTE
Both ends of the link must be configured to operate on the same channel
bandwidth.

This section describes factors to be taken into account when choosing sites for the
ODU, PIDU Plus and PTP-SYNC unit (if installed).
ODU site 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 4-67.
•
Height and location to achieve the best radio path.
•
Height in relation to other objects with regard to lightning strikes.
•
Aesthetics and planning permission issues.
•
Cable lengths; see Maximum cable lengths on page 2-7.
•
The effect of strong winds on the installation; see Wind loading on page 2-7.
PIDU Plus site selection
When selecting a site for the PIDU Plus, consider the following factors:
•
Indoor location with no possibility of condensation.
•
Availability of a mains electricity supply.
•
Accessibility for viewing status indicators and pressing Recovery switch.
•
Cable lengths; see Maximum cable lengths on page 2-7.
PTP-SYNC site selection
If PTP-SYNC is to be installed, consider the following factors when selecting a site:
•
Indoor location, or outdoor in a weatherproofed cabinet, with no possibility of
condensation.
•
Accessibility for viewing status indicators.
•
Cable lengths; see Maximum cable lengths on page 2-7.

Wind loading
Ensure that the site 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.
Calculation of lateral force
The ODU, with or without the integral antenna, is essentially a flat structure and so
the magnitude of the lateral force can be estimated from:
Force (in pounds) = 0.0042 . A . v2
Where A is the surface area in square feet and v is the wind speed in miles per hour.
The lateral force produced by a single PTP 300 or PTP 500 ODU (integrated or
connectorized model) at different wind speeds is shown in Table 2-2 and Table 2-3.

speeds up to 242 kph (151 mph). Ensure that the structure to which the ODU is fixed
to is also capable of withstanding the prevalent wind speeds and loads.
Wind speed statistics
Contact the national meteorological office for the country concerned to identify the
likely wind speeds prevalent at the proposed location. Use this data to estimate the
total wind loading on the support structures. Sources of information:

PTP 300 and PTP 500 Series User Guide
Link planning
Link planning
Link planning must take account of range, obstructions and path loss.
Range and obstacles
Calculate the range of the link and identify any obstacles that may affect radio
performance.
Performed 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.
The PTP 300 and PTP 500 Series are designed to operate in Non-Line-of-Sight (NLoS)
and Line-of-Sight (LoS) environments. An NLOS environment is one in which there is
no optical line-of-sight, that is, there are obstructions between the antennas.
The bridge operates at ranges from 100 m (330 ft) to 250 km (155 miles). Operation of
the system will depend on obstacles in the path between the units. Operation at 40 km
(25 miles) or above requires a near line of sight path. Operation at 100m (330 ft) may
be achieved with one unit totally obscured from the other unit, but with the penalty of
transmitting at higher power in a non-optimal direction, thereby increasing
interference in the band.
NOTE
In radar detection regions, the minimum LoS operating range with
integrated antennas is 300 meters (990 ft). When higher gain connectorized
antennas are used, operation with a predicted receiver signal level of 45
dBm or higher is not recommended.
PTP LINKPlanner
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.

Chapter 2 Planning considerations
PTP LINKPlanner for synchronized networks (PTP 500 only)
TDD synchronization should be planned using PTP LINKPlanner. This will provide the
necessary TDD Frame parameter values which are required to complete a
synchronized installation. Please refer to the PTP LINKPlanner User Guide.
Using Line Of Sight Mode (PTP 300 only)
To permit higher data throughput rates over links of range 10 km (6.2 miles) or less,
the PTP 300 Series Bridge can be configured to operate with Line Of Site mode
enabled.
The line of sight capability must be enabled in the license key. This requires purchase
of an upgrade access key.
Line Of Site mode may be used only when the path is completely unobstructed and the
link range is less than 10 km (6 miles). An unobstructed path is one in which the first
Fresnel zone is clear of obstructions and there is zero excess path loss. The PTP
LINKPlanner provides capabilities to check for obstructions in the path.
CAUTION
The link may suffer severely reduced data rate and availability if the LOS
mode is enabled in a link with an obstructed path.
The Line Of Sight mode control is in the Installation Wizard. If the user selects LOS
mode and the link range clearly exceeds 10 km (6.2 miles), the unit automatically
disables LOS mode and data rates, and raises a "Line Of Sight Mode Inactive" front
panel alarm and email alert.
Path loss considerations
Path loss is the amount of attenuation the radio signal undergoes between the two
ends of the link.
Calculating path 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
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.
For minimum error rates on TDM links, the maximum modulation mode should be
limited to 64QAM 0.75.
The values for (BPSK) are static receive sensitivity measurements. The other values
are static receive sensitivity measurements with an AMOD threshold applied. The
AMOD threshold applied is for a benign radio channel.
When selecting a modulation mode, the system is influenced by the parameters listed
in Table 2-4.

Chapter 2 Planning considerations
Parameter
Meaning
AMOD Threshold
The combined receive input signal level on both horizontal
and vertical inputs that results in the link consistently
entering the receive modulation mode under consideration as
the signal level is increased.
System Threshold
Thresholds for all modes except BPSK are for the relevant
link optimization AMOD thresholds. System threshold for
BPSK is the RPSK receive sensitivity.
Max Link Loss
The maximum link loss for each modulation mode is derived
from the AMOD threshold for that mode (sensitivity threshold
for BPSK) and the maximum region 1 center channel output
power. The figures assume integral antennas are used, with
gain 23 dBi (5.8 GHz and 5.4 GHz).
When to install connectorized units
The majority of radio links can be successfully deployed with the integrated PTP 300
or PTP 500 Series. 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 (>80 km or >50 miles) extend over water.
•
Where there are known to be high levels of interference.
NOTE
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 lightning protection
Chapter 2 Planning considerations
Grounding and lightning protection
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 300 and PTP 500 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.
Standards
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.
Lightning protection zones
The ‘rolling sphere method’ 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.
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.

General protection requirements
To adequately protect a PTP 300 or PTP 500 installation, both ground bonding and
transient voltage surge suppression are required.
NOTE
Where an installation already has, or requires the use of a Master Ground
Bar then the requirements of Motorola specification R56: Standards And

Grounding and lightning protection
Chapter 2 Planning considerations
Basic requirements
The following basic protection requirements must be implemented:
•
The equipment (ODU or GPS receiver for PTP-SYNC) must be in ‘Zone B’ (see
Lightning protection zones on page 2-14).
•
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 cable requirements
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.

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.

Data network planning
VLAN membership
Decide if the IP interface of the ODU management agent will be connected in a VLAN.
If so, decide if this is a standard (IEEE 802.1Q) VLAN or provider bridged (IEEE
802.1ad) VLAN, and select the VLAN ID for this VLAN.
Use of a separate management VLAN is strongly recommended. Use of the
management VLAN helps to ensure that the ODU management agent cannot be
accessed by customers.
Priority for management traffic
Choose the Ethernet priority for management traffic generated within the ODU
management agent. The priority should be selected so as to be consistent with existing
policy on priority of management traffic in the network. Use of a high priority is
strongly recommended to ensure that management traffic is not discarded if the link is
overloaded.
IP interface
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 and VLAN.
Find out the correct subnet mask and gateway IP address for this network segment
and VLAN.
Ensure that the design of the data network permits bi-direction 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.

Quality of service for bridged Ethernet traffic
Choose an appropriate assignment between the priority code point in bridged Ethernet
frames and traffic classes. This assignment should be consistent with quality of service
policy in the rest of the customer data network.
The user interface provides a convenient shortcut to select the assignment
recommended in IEEE 802.1Q-2005.
NOTE
Ethernet priority information is coded in the Ethernet VLAN tag and
differentiated quality of service is therefore not available in a network based
on untagged Ethernet frames.
Back to back links
Avoid the use of direct cabled connections between two PIDUs. 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 Ethernet’ switches
Do not connect PTP 300 or PTP 500 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

Enabling SNMP
Enable the SNMP interface for use by configuring the following attributes in the
Remote Management page:
•
SNMP State (default disabled)
•
SNMP Version (default SNMPv1/2c)
•
SNMP Port Number (default 161)
When the SNMP Version is set to SNMPv1/2c the interface must be additionally
configured by entering the following attributes:
•
SNMP Trap IP Address
•
SNMP Trap Port Number
•
SNMP Community String

Planning for SNMPv3 operation
SNMP security mode
Decide how SNMPv3 security will be configured.
MIB-based security management uses standard SNMPv3 MIBs to configure the userbased security model and the view-based access control model. This approach provides
considerable flexibility, allowing a network operator to tailor views and security levels
appropriate for different types of user. MIB-based security management may allow a
network operator to take advantage of built-in security management capabilities of
existing network managers.
Web-based security management allows an operator to configure users, security
levels, privacy and authentication protocols, and passphrases using the web-based
management interface. The capabilities supported are somewhat less flexible than
those supported using the MIB-based security management, but will be sufficient in
many applications. Selection of web-based management for SNMPv3 security disables
the MIB-based security management. The system does not support concurrent use of
MIB-based and web-based management of SNMPv3 security.

Chapter 2 Planning considerations
Web-based management of SNMPv3 security
Identify the format used for SNMP Engine ID. Three formats are available:
•
MAC address (default)
•
IP address
•
Text string
If SNMP Engine ID will be based on a text string, identify the text string required by
the network management system. This is often based on some identifier that survives
replacement of the PTP hardware.
Identify the user names and security roles of initial SNMPv3 users. Two security roles
are available:
•
Read Only
•
System Administrator
Identify the security level for each of the security roles. Three security levels are
available:
•
No authentication, no privacy
•
Authentication, no privacy
•
Authentication, privacy
If authentication is required, identify the protocol. Two authentication protocols are
available:
•
MD5
•
SHA
If privacy will be used, identify the protocol. Two privacy protocols are available:
•
DES
•
AES
AES link encryption is only available to users who have purchased an appropriate
license key.
If authentication or authentication and privacy protocols are required, identify
passphrases for each protocol for each SNMP user. It is considered good practice to
use different passphrases for authentication and privacy. Passphrases must have
length between 8 and 32 characters, and may contain any of the characters listed in
Table 2-5.

Antenna specifications
Antenna specifications
This section contains specifications of the antennas that are approved for use with the
connectorized ODUs.
For more information on antenna restrictions, refer to Regulatory issues with
connectorized units on page 4-62.
Antenna selection criteria
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.
Non-FCC regions
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 Conformance to
regulations on page 2-2.
FCC regions
In FCC regions, antenna choice is restricted as described in FCC antenna restrictions
(5.4 GHz) on page 4-20 and FCC antenna restrictions (5.8 GHz) on page 4-23.

Chapter 4 Reference information
FCC antenna restrictions (5.4 GHz)
In FCC regions, external antennas from the list in Table 4-20 can be used with the
Connectorized version of the PTP 54300 and PTP 54500. 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 34.9 dBi (33.4 dBi for 5 MHz bandwidth)
per polarization or antenna.
However, the Maximum Transmit Power must be reduced to avoid exceeding the EIRP
limits.
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 54300 and PTP
54500. The required antenna impedance is 50 ohms.

Transmit power reduction at the band edges
Operation at or near the 5.8 GHz band edges can results in a lower maximum transmit
power. In some configurations the system reduces the power when operating at the
edge channels. The amount of reduction, if any, is dependant on the region code of the
region of operation. This currently only affects systems configured with region code 1.
The maximum powers at the edge channels for 5 MHz, 10 MHz and 15 MHz are
presented in Table 4-35 (for region code 1 ONLY).

Chapter 4 Reference information
Compliance with regulations
Changes or modifications not expressly approved by Motorola could void the user’s
authority to operate the system.
This system has achieved Type Approval in various countries around the world. This
means that the system has been tested against various local technical regulations and
found to comply. The frequency bands in which the system operates may be
‘unlicensed’ and, in these bands, the system can be used provided it does not cause
interference. Further, it is not guaranteed protection against interference from other
products and installations.
CAUTION
When planning a link that will use Connectorized PTP 300 or PTP 500 Series
(with external antennas), ensure that regulatory requirements are met for the
installation, as described in Regulatory issues with connectorized units on page
4-62.
FCC and ETSI compliance testing (without PTP-SYNC)
Without PTP-SYNC installed, the system has been tested for compliance to both US
(FCC) and European (ETSI) specifications. It has been shown to comply with the limits
for emitted spurious radiation for a Class B digital device, pursuant to Part 15 of the
FCC Rules in the USA and appropriate European ENs. These limits have been
designed to provide reasonable protection against harmful interference. However the
equipment can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to other radio
communications. There is no guarantee that interference will not occur in a particular
installation.
NOTE
A Class B Digital Device is a device that is marketed for use in a residential
environment, notwithstanding use in commercial, business and industrial
environments.
NOTE
Notwithstanding that Motorola has designed (and qualified) the PTP 300 and
PTP 500 products to generally meet the Class B requirement to minimize the
potential for interference, the PTP 300 and PTP 500 product ranges are not
marketed for use in a residential environment.

FCC and ETSI compliance testing (with PTP-SYNC)
With PTP-SYNC installed, this equipment has been tested and found to comply with the
limits for a Class B digital device, provided that the PIDU Plus is correctly grounded as
described in Indoor CAT5e cable on page 4-18.
Radio and television interference
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 PIDU Plus into a power outlet on a circuit different from
that to which the receiver is connected.
•
Consult your installer or supplier for help.
Deployment and operation
The Radio Regulations of various countries’ limits constrain the operation of radio
products generally. In particular the local regulator may limit the amount of conducted
or radiated transmitter power and may require registration of the radio link.
The power transmitted by the PTP 300 and PTP 500 Series is controlled by the use of
region-specific license keys. Contact your supplier/installer to ensure that your
product is set for the correct license key for your country and region and to ensure
that you have fulfilled all the local regulatory requirements, especially if you are
intending to use a link with external antennas.

Maximum EIRP for connectorized units
In most regions (including USA, Canada, Europe and Australia) 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 Bandwidth) dBm.
In some regions (including Europe) operation of products in the band 5725 MHz to
5850/5875 MHz is constrained by an EIRP limit. The constraint is that the EIRP must
not exceed 36 dBm or (23 + 10 x Log Bandwidth) dBm.
As the products have an operating bandwidth from approximately 5 MHz to
approximately 15 MHz, then the maximum allowed EIRP depends on the operating
bandwidth of the radio as shown in Table 4-54.

Calculating EIRP for connectorized units
When operating with external antennas, the installer or operator has to set the
maximum transmit power to ensure that the EIRP limit is not exceeded. The EIRP may
be calculated from:
Allowed EIRP(dBm) =
Max_Transmit_Power (dBm) + Antenna Gain (dBi) – Feeder Losses (dB)
and hence:
Max_Transmit_Power (dBm) =
Allowed EIRP(dBm) – Antenna Gain (dBi) + Feeder Losses (dB)

The Set_Max_Transmit_Power parameter for connectorized units
As the actual maximum transmit power can only be adjusted in 1 dB steps, then the
installer or operator must configure the system to have a Set_Max_Transmit_Power
parameter as calculated below:
Set_Max_Transmit_Power = [Max_Transmit_Power] rounded down to nearest
lower dB step
In order to simplify matters, the settings to be used for regions with the EIRP limits in
Table 4-54 (assuming short feeder cables) are shown in Table 4-55.

NOTE
Gain of antenna in dBi = 10*log(G).
The regulations require that the power used for the calculations is the
maximum power in the transmit burst subject to allowance for source-based
time-averaging.
At 5.4 GHz and EU 5.8 GHz, the products are generally limited to a fixed
EIRP which can be achieved with the Integrated Antenna. The calculations
above assume that the maximum EIRP allowed by the regulations is being
transmitted.
NOTE
If there are no EIRP limits in the country of deployment, use the distance
calculations for FCC 5.8 GHz for all frequency bands.
At FCC 5.8 GHz, for antennas between 0.6m (2ft) and 1.8m (6ft), alter the
distance proportionally to the antenna gain.

This section provides instructions, tables and graphs to allow calculation of the data
rate capacity that can be provided by alternative PTP 300 and PTP 500 configurations.
The following topics are described in this section:
•
Data rate defined on page 4-77
•
Calculation procedure and example on page 4-78
•
Data throughput capacity on page 4-80
•
Range adjustment curves on page 4-87
Data rate defined
The data rate capacity of a PTP link is defined as the maximum end-to-end Ethernet
throughput (including Ethernet headers) that it can support. It is assumed that
Ethernet frames are 1500 octet. Data rate capacity is determined by the following
factors:
•
Product (PTP 300 or PTP 500)
•
Link Symmetry
•
Link Mode Optimization (IP or TDM)
•
Modulation Mode
•
Channel Bandwidth
•
Link Range

Calculation procedure and example
Procedure
To calculate the data rate capacity of a PTP 300 or PTP 500 link, perform Procedure
4-1.
Procedure 4-1 Calculating data rate capacity
1
Use the tables in Data throughput capacity on page 4-80 to look
up the data throughput capacity rates (Tx, Rx and Both) for the
required combination of:
Product (PTP 300 or PTP 500)
Link Symmetry
Link Mode Optimization
Modulation Mode
Channel Bandwidth
2
The tables contain data rates for links of zero range. Use the
curves in Range adjustment curves on page 4-87 to look up the
Throughput Factor that must be applied to adjust the data rates
for the actual range of the link.
3
Multiply the data rates by the Throughput Factor to give the
throughput capacity of the link.
NOTE
There is a small difference between the rates for IP and TDM because there
is fragmentation in TDM (for low priority traffic) which causes the
throughput to be reduced buy approximately 1% compared to the IP mode.

Data rate calculations
Example
Suppose that the link characteristics are:
•
Product = PTP 500
•
Link Symmetry = 1:1
•
Link Mode Optimization = TDM
•
Modulation Mode = 64QAM 0.83 Dual
•
Channel Bandwidth = 10 MHz
•
Link Range = 55 km
To calculate the throughput capacity of the link, proceed as follows:
Procedure 4-2 Example of data rate capacity calculation
1
Use Table 4-65 to look up the data throughput capacity rates:
Tx = 32.78
Rx = 32.78
Both = 65.56
2
Use Figure 4-8 to look up the Throughput Factor for 1:1, TDM and Link
Range 55 km. The factor is 0.7.
3
Multiply the rates from Step 2 by the Throughput Factor from Step 3 to
give the throughput capacity of the link:
Tx = 22.95
Rx = 22.95
Both = 45.89
If the product is a PTP 500 Lite, divide these figures by 2.

Chapter 4 Reference information
Data throughput capacity
The following tables show the data throughput rates (Mbits/s) that are achieved when
the link distance (range) is 0 km:
•
Table 4-60 - PTP 300, link symmetry = adaptive or 3:1
•
Table 4-61 - PTP 300, link symmetry 1:1, link optimization IP
•
Table 4-62 - PTP 300, link symmetry 1:1, link optimization TDM
•
Table 4-63 - PTP 500 Full, link symmetry = adaptive or 3:1
•
Table 4-64 - PTP 500 Full, link symmetry 1:1, link optimization IP
•
Table 4-65 - PTP 500 Full, link symmetry 1:1, link optimization TDM
Use the curves in Range adjustment curves on page 4-87 to adjust these figures to
allow for link range
NOTE
When using these tables, be aware of the factors that affect data throughput,
as listed below.
Data throughput capacity is restricted by the following factors:
•
Throughput for Link Symmetry 3:1 is the same as that for 1:3, but the Tx and Rx
data rates are swapped.
•
The data rates for Adaptive symmetry apply to the most asymmetric case where
the link has significant offered traffic in one direction only. The data rates for
Adaptive symmetry with bidirectional offered traffic are the same as those for
Link Symmetry = 1:1 with Link Optimization = IP.
•
PTP 500 Lite data rates are half the quoted PTP 500 Full rates.

Insert the eight contacts into the connector body in accordance with
Table 5-1. It is easiest to insert the pins from the inside out, in the order
12, 11, 9, 5, 4, 3, 2, 1. Push the contacts in so that the shoulder on the
contact fits into the hole in the connector shell. When all contacts have
been fitted, push them in further to engage with the locking mechanism
in the connector shell. This can be done by applying pressure to the
contact with a small diameter stiff object, such as tweezers.
If a contact is pushed in to the point where the locking mechanism
engages before all of the contacts have been inserted it will limit the
amount of room available to fit the remaining contacts, requiring harder
bends to be applied.
6
Fit the adaptor to the connector shell. The plastic ring fits inside the
rubber boot and ensures a tight fit when the adaptor body is clipped onto
the connector shell. Be aware that the adaptor body is a hard push fit
onto the connector shell.

Meaning
This attribute controls how the unit identifies and connects to
the correct peer unit. There are two methods:
‘Link Access’ means that each unit must be configured with a
Target MAC Address equal to the actual MAC address of its
peer.
‘Link Name Access’ means that both units must be configured
with the same Link Name.
Link Name
Only displayed when Access Method is set to ‘Link Name
Access’. A link can only be established between units that
have identical Link Names.
Link Name may consist of letters (A-Z and a-z), numbers
(0-9), spaces, and the following special characters:
(),-.,:<=>[]_{}
Target MAC
Address
This is only displayed when Access Method is set to ‘Link
Access’. This is the MAC Address of the peer unit that will be
at the other end of the wireless link. This is used by the
system to ensure the unit establishes a wireless link to the
correct peer. The MAC Address can be found embedded
within the serial number of the unit. The last six characters of
the serial number are the last three bytes of the unit’s MAC
address.
NOTE
A PTP 300 or PTP 500 Series system is shipped as a pair
of units with pre-loaded correct MAC addresses. Target
MAC addresses will only need to be entered if an existing
unit has to be replaced in the field or the units
configuration has been erased.

Attribute
Dual Payload
Chapter 6 Configuration and alignment
Meaning
This controls whether the link takes advantage of the channel
condition to increase the link throughput. If set to ‘Disable’,
the robustness of the link is improved. The default value is
‘Enabled’.
This control is automatically set to ‘Enabled’ if either E1 or
T1 is enabled and Lowest Telecoms Modulation Mode is set to
a Dual Payload modulation.
Master Slave
Mode
At this point it is necessary to decide which end will
designate a Master. The Master unit is the controlling unit
with respect to the point-to-point link and its maintenance.
The master transmits until the link is made, while the Slave
listens for its peer and only transmits when the peer has been
identified.
Link Mode
Optimization
Optimizes the link behavior according to the type of traffic
that will be bridged. There are two modes to choose from: IP
and TDM. For more information, see Link mode optimization
on page 1-21.

Attribute
Link Symmetry
Chapter 6 Configuration and alignment
Meaning
(Master only) Values of "Adaptive", "3 to 1", "1 to 1" and
"1 to 3" can be selected. The adaptive setting allows link
symmetry to vary dynamically in response to offered traffic
load. The remaining values select three options for fixed
division between transmit and receive time in the TDD frame
of the master ODU. The first number in the ratio represents
the time allowed for the transmit direction and the second
number represents the time allowed for the receive direction.
The appropriate matching Link Symmetry is set at the slave
ODU automatically. For example, if Link Symmetry is
configured as ‘3 to 1’ at the master ODU, then the slave ODU
will be set automatically as ‘1 to 3’. In this example, the
master-slave direction has triple the capacity of the slavemaster direction.
Link Symmetry is subject to the following restrictions:
‘Adaptive’ is not supported in regions where radar
avoidance is in use.
‘Adaptive’ is not supported when link optimization is set
to ‘TDM’.
‘Adaptive’ is not supported in 5 MHz channel bandwidth.
‘3 to 1’ and ‘1 to 3’ are not supported in 5 MHz channel
bandwidth.
‘3 to 1’ and ‘1 to 3’ are not supported when E1/T1
services are enabled.
Spectrum
Management
Control
Is used to configure the Spectrum Management features, see
Managing spectrum on page 7-20 for more details. In regions
that do not mandate DFS (Radar Detection), the Spectrum
Management Control options are ‘i-DFS’ and ‘Fixed

the Spectrum Management Control options are ‘DFS’ and
‘DFS with i-DFS’.

Attribute
Lower Center
Frequency
Meaning
Not displayed when Spectrum Management Control is set to
‘Fixed Frequency’. The software allows a user to optionally
adjust the channel center frequencies. Changing the Lower
Center Frequency attribute causes all channel center
frequencies to be offset. It effectively slides the
channelization up or down.
CAUTION
The lower center frequency attribute must be configured
to the same value for both the master and slave. Failure
to do so will cause the wireless link to fail
reestablishment. The only way to recover from this
situation is to modify the Lower Center Frequency
attribute so that they are identical on both the master
and slave unit.
Default Raster
This is only displayed when Spectrum Management Control is
set to ‘Fixed Frequency’. If this is set to ‘On’, the list of
options presented in the fixed Tx frequency box is limited by
the default raster.

Fixed Tx
Frequency, Fixed
Rx Frequency
Chapter 6 Configuration and alignment
Meaning
This is only displayed when Spectrum Management Control is
set to ‘Fixed Frequency’. The software allows a user to
optionally fix the Transmit and the Receive frequencies for a
wireless link. The settings must be compatible at each end of
the link. Once configured, the spectrum management
software will not attempt to move the wireless link to a
channel with lower co-channel or adjacent channel
interference. Therefore this mode of operation is only
recommended for deployments where the installer has a good
understanding of the prevailing interference environment.
Figure 6-29 shows an example fixed frequency configuration
for a 15 MHz channel bandwidth. In this example, the Fixed
Transmit Frequency is set to 5735 MHz and the Fixed
Receive Frequency is set to 5735 MHz. Care must be taken
when configuring the Fixed Transmit and Receive
Frequencies to ensure that both frequencies are on the same
channel raster as the Lower Center Frequency. For example,
if the channel raster is 5 MHz, both the Fixed Transmit and
Receive Frequencies must be a multiple of 5 MHz from the
Lower Center Frequency (5740 = 5735 + 5 MHz) and (5745
= 5735 + 5 MHz x 2).
NOTE
A raster limits the selection of the Rx frequency based
upon the setting of the Tx frequency.
Installation Tones
‘Disabled’ means that audio tones will not be emitted during
antenna alignment.
‘Enabled’ means that audio tones will be emitted during
antenna alignment (the recommended option).

Checking that the units are armed
Select menu option Home. The System Summary page is displayed. Check that the
Install Arm State is set to ‘Armed’ (Figure 6-33); this confirms that the units are ready
for alignment.
Figure 6-33 System Summary page (when unit is armed)
If the units are not armed, execute the installation wizard as described in Task 8:
Configuring wireless and telecoms interfaces on page 6-26.
Aligning antennas
Use this procedure to align linked antennas (master and slave), whether integrated or
connectorized.
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 6-47 before
starting alignment.
NOTE
To achieve best results, make small incremental changes to elevation and
azimuth.

Task 10: Aligning antennas
Chapter 6 Configuration and alignment
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:
Procedure 6-16 Align antennas
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 three recommended methods in Monitoring received signal
level on page 6-47).
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 three 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 the DVM
method (see Method #2: digital voltmeter (DVM) on page 6-50) the
graphical installation method (see Method #3: graphical install on
page 6-51) 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.

Aligning separate antennas for spatial diversity
If a connectorized ODU is installed at either site with two separate antennas for spatial
diversity, proceed as follows:
Procedure 6-17 Aligning spatial diversity antennas
1
Connect the horizontal polarization antenna to the ODU, disconnect the
vertical polarization antenna, then perform Aligning antennas on page
6-45.
2
Connect the vertical polarization antenna to the ODU, disconnect the
horizontal polarization antenna, then perform Aligning antennas on
page 6-45.
3
Re-connect the horizontal polarization antennas. The received signal
level should increase.
4
Weatherproof the antenna connections at the ‘H’ and ‘V’ interfaces of
the ODUs, as described in Mounting and connecting antennas on page
5-17.
Monitoring received signal level
The goal of antenna alignment is to find the center of the main beam. This is done by
adjusting the antennas while monitoring the receive signal level. Choose one of three
methods for monitoring receive signal level:
•
Method #1: ODU installation tones on page 6-48
•
Method #2: digital voltmeter (DVM) on page 6-50

Task 10: Aligning antennas
Chapter 6 Configuration and alignment
Method #1: ODU installation tones
This is the first of three methods that may be used to monitor receive signal level
during antenna alignment.
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.
NOTE
When using ODU installation tones to align connectorized antennas, it may
not be possible to hear the tones. To overcome this problem, either use an
assistant, or use a stethoscope to give a longer reach.
The tones and their meanings are described in Table 6-7. In each of the states detailed
in the table, align the unit to give the highest pitch tone.

PTP 300 and PTP 500 Series User Guide
Task 10: Aligning antennas
During alignment, the installation tones should exhibit the following behavior:
•
Band scan: When first started up and from time to time, the Master unit will
carry out a band scan to determine which channels are not in use. During this
time, between 10 and 15 seconds, the Master unit will not transmit and as a
consequence of this neither will the Slave unit. During this time the installation
tone on the master unit will drop back to the band scan state, and the Slave unit
will drop back to the Scanning state with the pitch of the tone set to the
background noise level. Alignment of the unit should cease during this time.
•
Radar detection: If the unit is operating where mandatory radar avoidance
algorithms are implemented, the ranging behavior may be affected. The Master
has to monitor the initially chosen channel for 60 seconds to make sure it is clear
of radar signals before transmitting. If a radar is detected during any of the
installation phases, a further compulsory 60 seconds channel scan will take place
as the master unit attempts to locate a new channel that is free of radar
interference.
•
Ranging: The PTP 300 and PTP 500 Series do not require the user to enter the
link range. The Master unit typically takes less than 60 seconds to determine the
length of the link being installed. The Master unit will remain in the Scanning
state until the range of the link has been established. The Master unit will only
move to the Synchronized state when the range of the link has been established.
The Slave unit does not have a ranging process. The slave unit will change to the
Synchronized state as soon as the wanted signal is demodulated.
•
Retrying same channel: If, at the end of the ranging period, the Registered
state is not achieved due to interference or other reasons, the Master unit will
retry twice more on the same channel before moving to another available
channel. Should this occur it might take a number of minutes to establish a link
in the Registered state.

Meaning
Region Code
The region code prohibits the wireless unit from operating
outside the regulated limits. An invalid region code indicates
a corrupted license key. Note that a change of state may
generate an SNMP trap and/or SMTP email alert.
Install Status
A non-OK value indicates that signaling was received with the
wrong MAC address. Note that it is very unusual to detect
this, because units with wrongly configured Target MAC
Address will normally fail to establish a wireless link.
However, rare circumstances may establish a partial wireless
link and detect this situation. NB: A non-OK value on start-up,
or a change of value during operation, may generate an
SNMP trap and/or SMTP email alert.

Alarm
Chapter 7 Operation
Meaning
Install Arm State
This alarm warns when a wireless unit is in installation mode.
After installation the wireless unit should be disarmed. This
will increase the wireless link’s data-carrying capacity and
stop the installation tone generator. The wireless link is
disarmed from the ‘Installation’ process, see Disarming the
units on page 6-52. A change of state may generate an SNMP
trap and/or SMTP email alert.
Unit Out Of
Calibration
The unit is out of calibration and must be returned to the
factory using the RMA process for re-calibration.
Incompatible
Region Codes
The PTP 300 and PTP 500 Series use region codes to comply
with local regulatory requirements governing the
transmission of wireless signals in the frequency bands in
which it operates. Region codes can only be changed by
obtaining a new PTP 300 or PTP 500 Series license key. If
this alarm is encountered, the appropriate license keys from
the country of operation should be obtained from your
distributor. Applying license keys containing the same region
codes to both ends of the link will remove the alarm. A
change of state may generate an SNMP trap and/or SMTP
email alert.
Incompatible
Master and Slave
A non-zero value indicates that the master and slave ends of
the wireless link are different hardware products, or have
different software versions. Note that it is very unusual to
detect this because incompatible units will normally fail to
establish a wireless link. However, some combinations may
establish a partial wireless link and detect this situation. Note
that a non-zero value may generate an SNMP trap and/or
SMTP email alert.
Ethernet
Configuration
Mismatch
The detection of Ethernet fragments (runt packets) when the
link is in full duplex is an indication of an auto-negotiation or
forced configuration mismatch. Note that a change of state
may generate an SNMP trap and/or SMTP email alert.
No Wireless
Channel Available
Spectrum Management was unable to locate a suitable
wireless channel to operate on. Note that a change of state
may generate an SNMP trap and/or SMTP email alert.

This warning is displayed if the Ethernet link has been
administratively disabled via the SNMP Interface. The
Ethernet Interface MIB-II ifAdminStatus attribute has been
set to DOWN. To enable the Ethernet interface, set the
ifAdminStatus attribute to UP. Note that a change of state
may generate an SNMP trap and/or SMTP email alert.
Ethernet Link
Status
Current status of the Ethernet link. If there are any problems
with the Ethernet interface, this alarm will be asserted. This
alarm will most likely be seen if the unit has no Ethernet
cable plugged into its Ethernet socket. Note that a change of
state may generate an SNMP trap and/or SMTP email alert.
Telecoms
Interface
Loopback
The loopback status of the telecoms channel. This is intended
for installation testing and should be set to 'None' for normal
operation. The wire connections to a unit can be tested by
applying a 'Copper' loopback to the local unit. The wireless
connection to the remote unit can be tested by applying a
'Wireless' loopback to the remote unit with no loopback on
the local unit.
A change of state may generate an SNMP trap and/or SMTP
email alert. The loopback can be disabled from the telecoms
configuration sub menu (see Performing a telecoms loopback
test on page 8-19).
TDD
Synchronization
Alarm
PTP 500 only. Indicates the current status of the TDD
Synchronization (OK, Timing System Failure, Not

Chapter 7 Operation
The status page can be configured to refresh itself at an operator defined rate (if the
user is logged in as system administrator). The refresh period defaults to 3600 seconds
and can easily be changed to refresh at any period between 2 seconds and 3600
seconds. Pressing the Update Page Refresh Period button causes a new page
refresh period to be adopted by the system. The page refresh mechanism uses an
HTML Meta refresh command. Therefore the refresh is always initiated by the local
browser and not by the ODU at this interval.
The two ODUs are arranged in a master and slave relationship. The roles of the units
in this relationship are displayed in the page title. The master unit will always have the
title ‘- Master’, and the slave will always have ‘- Slave’ appended to the ‘Systems
Status’ page title.
The status page attributes are defined in Table 7-5.

Region Code
The region code is used by the system to constrain the
wireless to operate within regulatory regime of the particular
country. The region code is encoded in the product license
key. If the operator wishes to change region code, a new
license key must be obtained from Motorola or the local pointto-point distributor or system integrator.
Elapsed Time
Indicator
The elapsed time indicator attribute presents the total time in
years, days, hours, minutes and seconds since the last system
restart. The system can restart for several reasons, for
example commanded reboot from the system reboot web
page, or a power cycle of the equipment.
Ethernet Link
Status
This indicates the current status of the Ethernet link. A state
of ‘Up’ with a green background indicates that an Ethernet
link is established. A state of ‘Down’ with a red background
indicates that the Ethernet link is not established.

that has full duplex transmission; one workstation can be
sending data on the line while another workstation is
receiving data.
Half Duplex data transmission means that data can be
transmitted in both directions on a signal carrier, but not at
the same time. For example, on a local area network using a
technology that has half duplex transmission, one workstation
can send data on the line and then immediately receive data
on the line from the same direction in which data was just
transmitted.

Telecoms Status
Chapter 7 Operation
Meaning
Indicate the current status of the telecoms channel. Channels
which are disabled during installation are marked as such.
Correctly operating channels display "Up" on a green
background, but alarm conditions (described in Alarm display
on page 7-7) have a red background.
The Telecoms Latency value, displayed in microseconds, is
determined when the wireless link starts and will remain the
same for a given wireless configuration. Section Telecoms
circuits on page 1-38 describes methods for reducing
telecoms latency on links which support high data rate
modulation modes.
Under normal circumstances the unit will freely transition
between modulation modes to suit the wireless conditions.
The "Single Payload Lock" indicates that the ODU will
prevent transitions from Single Payload modes to the higher
Dual Payload modes in order to avoid loss of telecoms data.
This field appears where such a transition would pass
through modes which cannot carry telecoms data. This may
be because, in order to control latency, the lowest modulation
mode has been set to a higher Single Payload mode.
In the absence of the Single Payload Lock the wireless will
transition to the faster Dual Payload modes as soon as the
conditions are appropriate. With the lock enabled, the
wireless will dwell in slower Single Payload modes whenever
there are operational telecoms links (operational links are
shown as "Up" in the telecoms channel field described
above). When the lock is actively preventing transitions, the
value displayed changes from "Enabled" to "Applied".

Status
As the attribute name suggests it displays the current status
of the wireless link. A state of ‘Up’ on a green background
indicates that a point-to-point link is established. A state of
‘Down’ on a red background indicates that the wireless link is
not established.
Maximum
Transmit Power
The maximum transmit power that the local wireless unit is
permitted to use to sustain a link.
Remote Maximum
Transmit Power
The maximum transmit power that the remote wireless unit is
permitted to use to sustain a link.
Transmit Power
Transmit power histogram is expressed in dBm and
presented as: max, mean, min, and latest. The max, min and
latest are true instantaneous measurements; the mean is the
mean of a set of one second means. See Histogram data on
page 7-19.
Receive Power
Receive power histogram is expressed in dBm and presented
as: max, mean, min, and latest. The max, min and latest are
true instantaneous measurements; the mean is the mean of a
set of one second means. See Histogram data on page 7-19.
Vector Error
The vector error measurement compares the received
signal’s In phase / Quadrature (IQ) modulation characteristics
to an ideal signal to determine the composite error vector
magnitude. The results are stored in an histogram and
expressed in dB and presented as: max, mean, min and latest.
The max, min and latest are true instantaneous
measurements; the mean is the mean of a set of one second
means. The expected range for Vector Error would be
approximately -1.5 dB (NLOS link operating at sensitivity
limit on BPSK 0.50) to –28 dB (short LOS link running
64QAM 0.83). See Histogram data on page 7-19.

Link Loss
Meaning
The link loss is the total attenuation of the wireless signal
between the two point-to-point units. See Histogram data on
page 7-19. The link loss calculation presented below:
Pll = PTx − PRx + g Tx + g Rx
Where:
Pll = Link Loss (dB)
PTx
= Transmit power of the remote wireless unit (dBm)
PRx
= Received signal power at the local unit (dBm)
gTx , g Rx
= Antenna gain at the remote and local units
respectively (dBi). The antenna gain of the ODU (23.5
dBi) is used unless one or both of the units is a
Connectorized version.
For connectorized ODUs, the link loss calculation is modified
to allow for the increased antenna gains at each end of the
link.
Transmit Data
Rate
The data rate in the transmit direction, expressed in Mbps
and presented as: max, mean, min, and latest in an histogram
format. The max, min and latest are true instantaneous
measurements; the mean is the mean of a set of one second
means. Expected data rates can be found in Data rate
calculations on page 4-77.
Receive Data Rate
The data rate in the receive direction, expressed in Mbps and
presented as: max, mean, min, and latest in an histogram
format. The max, min and latest are true instantaneous
measurements; the mean is the mean of a set of one second
means. Expected data rates can be found in Data rate
calculations on page 4-77.
Link Capacity
The maximum aggregate data rate capacity available for user
traffic, assuming the units have been connected using Gigabit
Ethernet. The link capacity is variable and depends on the
prevailing wireless conditions as well as the distance (range)
between the two wireless units.

Chapter 7 Operation
Managing spectrum
This section describes how to configure the spectrum management feature of the PTP
300 or PTP 500 and how to interpret spectrum management graphical plots.
This section contains the following procedures:
•
Configuring spectrum usage at the master on page 7-20
•
Viewing spectrum usage at the slave on page 7-23
•
Interpreting the spectrum management plots on page 7-25
•
Viewing the active channel history on page 7-33
•
Viewing historic spectrum management metrics on page 7-34
Configuring spectrum usage at the master
All spectrum management configuration changes are applied at the master ODU only.
These changes are then sent from the master to the slave, so that both master and
slave keep identical copies of spectrum management configuration. It is therefore
possible to swap master and slave roles on an active link without modifying Spectrum
Management configuration.
NOTE
Before attempting to improve the performance of the spectrum management
algorithm by changing the default configuration, consulting the Motorola
Point-to-Point distributor or one of the system field support engineers.
The default channelization can be modified by varying the lower center frequency
attribute in the installation wizard, as described in Step 2: Wireless configuration on
page 6-31.
To configure spectrum usage at the master, proceed as follows:
Procedure 7-1 Configure spectrum usage at the master
1
Log into the master ODU for the link.
2
Select menu option System, Spectrum Management. The Spectrum
Management page is displayed (Figure 7-8).

Hopping Margin
Spectrum Management uses this margin when making a
channel hop decision. If the interference level of the target
channel is lower than that of the active channel by at least the
Hopping Margin, the link will hop to the target channel. The
default setting is 3 dB in non-radar regions, or 10 dB in radar
regions.
Asymmetric DFS
Only displayed in non-radar regions when i-DFS is enabled.
The default configuration of symmetric operation constrains
the link to operate symmetrically, using the same transmit
and receive channels. When in symmetric mode the slave unit
will always follow the master. If the master moves to a new
channel the slave will hop to the same channel. When the
Point-to-Point link is configured as an asymmetric link both
the master and slave are free to select the best channel from
their own set of local interference metrics.
Spectrum
Management
Control
Only displayed in radar regions. The options are ‘DFS’ and
‘DFS with i-DFS’.
Hopping Period
The Spectrum Management algorithm evaluates the metrics
every ‘Hopping Period’ seconds (180 seconds by default)
looking for a channel with lower levels of interference. If a
better channel is located, Spectrum Management performs an
automated channel hop. If SNMP or SMTP alerts are enabled
an SNMP TRAP or an email alert is sent warning the system
administrator of the channel change.
Hopping Counter
This is used to record the number of channel hops. The
number in the (+) brackets indicates the number of channel
changes since the last screen refresh.

the composite vector error magnitude. The histogram is
calculated over a one hour period.
Link Loss
The link loss measurement is calculated as follows:
Peer_Tx_Power (dBm) – Local_Rx_Power (dBm) + 2 x
Antenna_Pattern (dBi)
The histogram is calculated over a one hour period.
Signal Strength
Ratio
The Signal Strength Ratio is:
Power received by the vertical antenna input (dB) ÷
Power received by the horizontal antenna input (dB)
This ratio is presented as: max, mean, min, and latest in an
histogram format. The max, min and latest are true
instantaneous measurements; the mean is the mean of a set
of one second means. See Histogram data on page 7-19.
Transmit Data
Rate
The data rate in the transmit direction, expressed in Mbps
and presented as: max, mean, min, and latest in an histogram
format. The max, min and latest are true instantaneous
measurements; the mean is the mean of a set of one second
means. Expected data rates can be found in Data rate
calculations on page 4-77.

Measurement
Period
The time over which the system histograms were collected.
Signal Strength 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 Signal Strength Ratio. This indicates the
antenna system is doing exactly as intended.

illuminates, there should be a 45 second delay, following which the yellow Ethernet
LED should flash 10 times.
If the Ethernet LED did not flash 10 times, proceed as follows:
Procedure 8-7 Ethernet LED did not flash 10 times
1
Remove and examine the cable that connects the PIDU Plus to the LPU
or ODU.
2
Check that the wiring to pins 4&5 and 7&8 is correct. For example, the
wiring to pins 4 and 7 may be crossed.
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.
5
Check that the PWR LED near the top right of the LPU PCB is
illuminated to indicate power in the Ethernet cable (Figure 8-3).
6
If any test fails, replace or repair the cable that connects the PIDU Plus
to the LPU or ODU.

No Ethernet activity
If the Ethernet LED did flash 10 times but then went off, proceed as follows:
Procedure 8-8 Ethernet LED flashed 10 times then went out
1
Check that the RJ45 connection from the LAN port of the PIDU Plus to
the PC is working.
2
If the PC connection is working, remove and examine the cable that
connects the PIDU Plus to the LPU or ODU.
3
Check that the wiring to pins 1&2 and 3&6 is correct. For example, the
wiring to pins 1 and 3 may be crossed.
4
If this test fails, replace or repair the cable that connects the PIDU Plus
to the LPU or ODU.
Irregular Ethernet activity
The yellow Ethernet LED should blink randomly as normal traffic passes through. If
the Ethernet LED flashes irregularly, for example there is a short flash followed by a
long flash, this indicates that the ODU has booted in recovery mode. The causes may
be installation wiring or a corrupt ODU software load. For more information, see Using
recovery mode on page 7-53.
Connection is not 100 BaseT
If the Ethernet connection to the network is only 10 BaseT, when 100 BaseT is
expected, proceed as follows:
Procedure 8-9 Connection is not 100 BaseT
1
Remove and examine the cable that connects the PIDU Plus to the LPU
or ODU.
2
Check that the wiring to pins 4&5 and 7&8 is correct. For example, the
wiring to pins 4 and 7 may be crossed.
3
If this test fails, replace or repair the cable that connects the PIDU Plus
to the LPU or ODU.

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 8-10.
4
Check the Ethernet Rx Crc And Align counter. The test has passed if
this is less than 10.
Test Ethernet packet errors reported by managed switch or
router
If the ODU is connected to a managed Ethernet switch or router, it may be possible to
monitor the error rate of Ethernet packets. Please refer to the user guide of the
managed network equipment.

Test ping packet loss
Using a computer, it is possible to generate and monitor packets lost between the
PIDU Plus and the ODU. This can be achieved by executing the Command Prompt
application which is supplied as standard with Windows and MAC operating systems.
To test ping packet loss, proceed as follows:
Procedure 8-11 Test ping packet loss
1
Ensure that the IP address of the computer is configured appropriately
for connection to the ODU under test.
2
Ensure that the IP address of the computer does not clash with other
devices connected to the network.
3
If the PIDU Plus is connected to an Ethernet switch or router then
connect the computer to a spare port, if available.
4
If it is not possible to connect the computer to a spare port of an
Ethernet switch or router, then the PIDU Plus 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 PIDU Plus from the network.
Connect the computer directly to the LAN port of the PIDU Plus.
5
On the computer, open the Command Prompt application.

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.
7
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 resistance at the PIDU Plus end of the 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 PIDU Plus. 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 are example values and

Testing PTP-SYNC
Refer to Table 1-6 for descriptions of the PTP-SYNC LEDs.
LEDs do not illuminate
Ensure that there is a cable connection between the PIDU Plus ‘ODU’ interface and
the ‘PIDU IN’ interface of the PTP-SYNC unit.
The ‘STATUS’ LED does not blink
This probably indicates that a 1PPS synchronization pulse is not detected by the PTPSYNC unit (no satellite lock).
Depending on system configuration, take one of the following actions:
•
System using a GPS receiver module - Ensure that there is a cable connection
between the PTP-SYNC ‘GPS/SYNC IN’ interface and the LPU, also that there is a
cable connection between the LPU and the GPS receiver module. Check that the
GPS receiver module has an uninterrupted view of the sky.
•
System using an alternative 1PPS timing source - Ensure that there is a cable
connection between the PTP-SYNC ‘GPS/SYNC IN’ or ‘1PPS IN’ interface and the
1PPS timing source.
•
On cluster slave units – Ensure that there is a cable connection between the slave
GPS/SYNC IN interface and the SYNC OUT interface of the preceding unit in the
chain.
The ‘ODU’ LED does not illuminate within 90 seconds of powerup
This probably indicates that there is no communication between PTP-SYNC and ODU
Ensure that the PTP-SYNC ‘ODU OUT’ interface is connected to the ODU (and LPUs if
installed) via the drop cable .

Testing a telecoms link
If an E1 or T1 link has been installed, it may be helpful to test the link by performing a
loopback test.
This task consists of the following procedure:
•
Performing a telecoms loopback test on page 8-19
Performing a telecoms loopback test
The loopback test allows the telecoms data stream to be looped back at the copper or
wireless interface. A typical T1 or E1 installation might include a ‘Copper’ loopback on
the local unit followed by a ‘Wireless’ loopback on the remote unit.
NOTE
The Telecoms page is only available when the Telecoms Interface has been
set to either T1 or E1, as described in Task 8: Configuring wireless and
telecoms interfaces on page 6-26.
To perform a loopback test, proceed as follows:
Procedure 8-15 Configure telecoms circuits for network
1
Select menu option System, Configuration, Telecoms. The Telecoms
page is displayed (Figure 8-5).
2
Select the Telecoms Loopback option: ‘Copper’ or ‘Wireless’ (Table 8-3).
3
Select Submit Updated System Configuration.
4
Perform loopback tests.
5

Connects the received data on a given telecoms interface to
the transmit interface.
May be used, in conjunction with a Bit Error Rate Tester, to
confirm that the correct connections have been made to the
ODU. This mode cannot be used for resistance tests, as it is
only capable of looping back valid telecoms signals.
Wireless
Sends the telecoms data received from the wireless link back
across the link on the same telecoms channel.
The link may be checked using, for example, a Bit Error Rate
Tester to ensure that no errors are detected.
