PTP 59600 available spectrum settings
The available spectrum settings for the PTP 59600 are illustrated in this section.
Adjustment of the lower centre frequency allows the operator to slide the available
frequency settings up and down the 5.9 GHz band in steps of 2 MHz.
In the 30 MHz channel bandwidth (Figure 4-26) the PTP 59600 variant operates on a
10 MHz channel raster. In the 15 MHz (Figure 4-27), 10 MHz (Figure 4-28) and 5 MHz
(Figure 4-29) channel bandwidths, the PTP 59600 variant operates on a 6 MHz
channel raster. The channel raster is set to even centre frequencies.
NOTE
These tables contain data for one typical region code. The specified channel
centre frequencies may not be available in other region codes.
The PTP 59600 product variant does not apply any band edge power reduction.

Data rate calculations
Data rate calculations
This section provides instructions, tables and graphs to allow calculation of the data
rate capacity that can be provided by alternative PTP 600 configurations.
The following topics are described in this section:
•
Data rate defined on page 4-99
•
Calculation procedure and example on page 4-99
•
Data throughput capacity on page 4-102
•
Range adjustment curves on page 4-113
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 variant (PTP 600 Full or Lite)
•
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 600 link, perform Procedure 4-1.

UNDER DEVELOPMENT

Data rate calculations
Chapter 4 Reference information
Procedure 4-1 Calculating data rate capacity
Use the tables in Data throughput capacity on page 4-102 to look up the
data throughput capacity rates (Tx, Rx and Both) for the required
combination of:
•
Link Symmetry
•
Link Mode Optimization
•
Modulation Mode
•
Channel Bandwidth
The tables contain data rates for PTP 600 Full only. If the ODUs are PTP
600 Lite, divide the data rates by 2.
The tables contain data rates for links of zero range. Use the curves in
Range adjustment curves on page 4-113 to look up the Throughput
Factor that must be applied to adjust the data rates for the actual range of
the link.
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 variant = PTP 600 Lite
•
Link Symmetry = 1:1
•
Link Mode Optimization = TDM
•
Modulation Mode = 64QAM 0.92 Dual
•
Channel Bandwidth = 10 MHz
•
Link Range = 60 km
The calculation procedure for this example is described in Procedure 4-2.
Procedure 4-2 Example of data rate capacity calculation
Use Table 4-63 to look up the data throughput capacity rates:
•
Tx = 41.41 Mbits/s
•
Rx = 41.41 Mbits/s
•
Both = 82.81 Mbits/s
Divide these rates by 2 to give PTP 600 Lite rates:
•
Tx = 20.70 Mbits/s
•
Rx = 20.70 Mbits/s
•
Both = 41.40 Mbits/s
Use Figure 4-38 to look up the Throughput Factor for 1:1, TDM and Link
Range 60 km. The factor is 0.86.
Multiply the rates from Step 2 by the Throughput Factor from Step 3 to
give the throughput capacity of the link:
•
Tx = 17.80 Mbits/s
•
Rx = 17.80 Mbits/s
•
Both = 35.60 Mbits/s

Data rate calculations
Chapter 4 Reference information
Data throughput capacity
Table 4-62, Table 4-63, Table 4-64, Table 4-65 and Table 4-66 show the data
throughput rates (Mbits/s) that are achieved when two PTP 600 Full ODUs are linked
and the link distance (range) is 0 km. Use the curves in Range adjustment curves on
page 4-113 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:
•
PTP 600 Lite data rates are half the PTP 600 Full rates given in this section.
•
Modulation Mode “256QAM 0.81 dual” is not available in all product variants and
channel bandwidths.
•
Throughput for Link Symmetry 2:1 is the same as that for 1:2, 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.

Cable connection procedures
This section describes three procedures that may be performed repeatedly in the
course of site installation:
•
Preparing the supported Superior Essex cable.
•
Installing a cable grounding kit.
•
Installing a lightning protection unit (LPU)
Preparing the supported Superior Essex cable
The maximum cable length between the ODU and the user’s network equipment is
100m (330 ft). Cable lengths up to 300m (984 ft) can be used where the PIDU Plus to
ODU cable is supplying power only, that is, when using the PTP 600 Series optical
interface.
For details of recommended cables and connectors, refer to Cables and connectors on
page 1-15.
WARNING
The copper screen of the supported Superior Essex cable is very
sharp and may cause personal injury. When preparing the Superior
Essex cable, take the following safety precautions:
ALWAYS wear cut resistant gloves (check the label to ensure they are cut
resistant).
ALWAYS wear protective eyewear.
ALWAYS use a rotary blade tool to strip the cable (DO NOT use a bladed
knife). To use the rotary blade tool, fit it around the outer cable sheaf and
rotate the cutter around the cable once or twice. The stripped outer
section can then be removed.

CAUTION
Check that the crimp tool matches the RJ45 connector being used, otherwise
the cable or connector may be damaged.
NOTE
The cable inner sheaf must be located correctly under the connector housing
tang. If this is not done correctly, there is no strain relief on the cable
terminations.
Both ends of the ODU cable are terminated in the same way. The above procedure
should be repeated for the PIDU Plus end of the cable when the cable routing process
is complete. This assumes that the installation uses PTP LPUs. If not, then the PIDU
Plus end of the cable does not require a Gland, but just the RJ45.
NOTE
The PIDU Plus end of the cable does not employ a cable gland.

there is no solder or flux residue on the outside of the contact. Care should also
be taken that the individual conductor insulation does not peel back with the
soldering heat, allowing possible shorts when assembled into the connector shell.
Fit four contacts into the unused locations, to provide strength and sealing.

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, pushed 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.
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.
Fit the strain relief clip.
Connect the adapter to the GPS, then wrap a layer of self-amalgamating tape,
starting 25mm below the bared back outer of the cable and finishing at the GPS

Using the ODU installation tones
The PTP 600 ODU emits audible tones during installation to assist with alignment. The
pitch of the alignment tone is proportional to the received power of the wireless
signals. Adjust the alignment of the unit in both azimuth and elevation until the
highest pitch tone is achieved. The tones and their meanings are described in Table

Chapter 5 Installation
CAUTION
If, when in the Synchronized or Registered state, the tone varies wildly,
there may be interference or a fast fading link. Installing in this situation
may not give a reliable link. Investigate the cause of the problem.
Aligning the units
To align the units, proceed as follows:
Procedure 5-18 Align Master and Slave
Adjust the elevation and azimuth of the Master unit to achieve an approximate
visual alignment with the site of the Slave unit.
Adjust the elevation and azimuth of the Slave unit to achieve an approximate
visual alignment with the site of the Master unit.
Without moving the Master unit, adjust the elevation and azimuth of the Slave
unit to achieve the highest pitch installation tone.
Without moving the Slave unit, adjust the elevation and azimuth of the Master
unit to achieve the highest pitch installation tone.
Repeat steps 3 and 4 as necessary to fine tune the alignment.
NOTE
To achieve best results, make small incremental changes to elevation and
azimuth.
There is a graphical installation screen (see Graphical install on page 6-75) available in
the web interface that displays the state of the link during the alignment process (up =
green, down = red).

User Guide: PTP 600 Series
Establishing a radio link
Behaviour during alignment
When the units are powered up and alignment begins, the following behavior may be
observed:
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 behaviour for the PTP 600 Series 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 Master unit can take up to 60 seconds in 0-40 km (0-25 miles) mode, 90 seconds in
0-130 km (0-81 miles) mode and 120 seconds in 0-200 km (0-124 miles) mode to
determine the range 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.

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.
Adjusting power settings
The transmit power levels of the installed units must be adjusted to ensure they are
not too high. Excessive power levels may cause saturation of the receivers or false
radar detection (in radar enabled regions), leading to degradation of link performance
and link failure.
To adjust power levels, proceed as follows:
Procedure 5-19 Adjust power levels
Consult the report generated by the LINKPlanner tool and note the Transmit
power recommended levels.
Set the local unit power equal to the “LOCAL - Max Transmit Power setting
while pointing” value from the LINKPlanner report.
Set the remote unit power equal to the “REMOTE - Max Transmit Power setting
while pointing” value from the LINKPlanner report.
Access each unit separately.
Align the units.
Repeat Step 2 and 3 using the values “LOCAL - Max Transmit Power setting
before disarm” and “REMOTE - Max Transmit Power setting before disarm” , if
different than the corresponding “while pointing” values.
Reboot the local unit then reboot the remote unit.
Disarm the units.

Home (system summary)
The home page for the PTP 600 Series (Figure 6-2) displays a high level summary of
the status of the wireless link and associated equipment.
Figure 6-2 System Summary page
The home page normally displays four key system attributes:
Wireless Link Status
The Wireless Link Status attribute displays the current status of the PTP 600 Series
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. If the link is down for an unknown reason the system administrator
should first consult the status web page for a more detailed summary of up to date
system diagnostics.

System alarms
The following system alarms are defined:
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.
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 Disarm installation on page 6-72. 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 600 Series uses 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 600 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.

Chapter 6 Operation
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.
SNTP Synchronization failed
This warning indicates that SNTP has been enabled but that the unit is unable to
synchronize with the specified SNTP server. Section SNTP (Simple Network Time
Protocol) on page 6-117 explains how to configure SNTP. Note that a change of state
may generate an SNMP trap and/or SMTP email alert.
Wireless Link Disabled Warning
This warning is displayed if the Wireless link has been administratively disabled via
the SNMP Interface (see Managing faults on page 6-112). The Wireless Interface MIBII 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 Disabled Warning
This warning is displayed if the Ethernet link has been administratively disabled via
the SNMP Interface (see Managing faults on page 6-112). The Ethernet Interface MIBII 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.

Fiber Link Status
If the fiber link is not OK, there are two possible causes: Either the fiber link has been
installed but disabled (because the license key does not include fiber support), or the
link could not be established even though an optical carrier was detected (due perhaps
to a broken TX fiber, or the link is disabled at the fiber link partner). Note that a
change of status may generate an SNMP trap and/or SMTP email alert.
Telecoms Channel A/B Status
Indicates one of the following alarm conditions on a telecoms channel:
Alarm Condition
Meaning
No Signal (Local)
There is no telecoms signal present at the connection to
the ODU at the local end.
No Signal (Remote)
There is an absence of telecoms data across the wireless
link.
No Signal (Local and
Remote)
The above two alarm conditions occur concurrently.
Remote Timing
There is insufficient wireless capacity available to carry
telecoms data. Under these conditions telecoms timing
information is still sent to keep the telecoms clocks
synchronized.
No Signal (Local)
and Remote Timing
Indicates both no local signal and remote timing.
In remote timing mode the ODU will transmit an Alarm Indication Signal (AIS),
consisting of all-ones, from the associated telecoms interface. A change of state may
generate an SNMP trap and/or SMTP email alert.
See Telecoms interface on page 6-57 for a description of the Telecoms Interface.
Telecoms Channel A/B Loopback
The loopback status of telecoms channel A and B. These are 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 Configuring the
telecoms circuits on page 6-49).

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 a HTML Meta
refresh command. Therefore the refresh is always initiated by the local browser and
not by the PTP 600 Series at this interval.
The two PTP 600 Series units 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 following attributes are displayed on the status page:
Link Name
The link name is allocated by the system administrator and is used to identify the
equipment on the network. The link name attribute is limited to a maximum size of 63
ASCII characters.
Site Name
The site name is allocated by the system administrator and can be used as a generic
scratch pad to describe the location of the equipment or any other equipment related
notes. The site name attribute is limited to a maximum size of 63 ASCII characters.
Software Version
The attribute describes the version of software installed on the equipment. The format
of the attributes is FFSSS-XX-YY where FF is the frequency variant (2.5, 4.5, 5.4, 5.8
or 5.9 GHz), SSS is the System Release, XX is the major release version and YY is the
minor release version.
Hardware Version
The hardware version attribute contains all the combined hardware version
information. The attribute is formatted as DXX-RYY-Z where DXX contain the version
of the digital card, RYY contains the version of the RF (radio frequency) card and Z
describes the antenna type which can be I (integrated) or C (connectorized).
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 point-to-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.
Ethernet Speed and Duplex
The negotiated speed and duplex setting of the Ethernet interface. The speed setting is
specified in Mbps.
Full Duplex data transmission means that data can be transmitted in both directions
on a signal carrier at the same time. For example, on a local area network with a
technology 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.
Remote IP Address
Hyperlink to the other side of the Link. The IP address of the peer link is displayed if
the Link is UP, otherwise “unavailable” is displayed.
Telecoms Channel A and B
Indicate the current status of the telecoms channels. Channels which are disabled
during installation are marked as such. Correctly operating channels display "Up" on a
green background, but alarm conditions (described in Section Home page alarm
display on page 6-6) 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 1-36 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".
TDD Synchronization
Displays the TDD Synchronization status for the link. For more information, refer to
TDD synchronization status on page 6-16.
Refresh Page Period
The Status page refreshes automatically according to the setting entered here (in
seconds). This attribute is only displayed when the user is logged on as System
Administrator.
Wireless Link 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

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

Expected data rates can be found in Data rate calculations on page 4-99.
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 of the prevailing wireless conditions as well as the distance (range) between
the two wireless units.
Transmit Modulation Mode
The modulation mode currently being used on the transmit channel. A list of all the
modulation modes can be found in Data rate calculations on page 4-99, where data
rate calculations plots are given for each available modulation mode.
Receive Modulation Mode
The modulation mode currently being used on the receive channel. A list of all the
modulation modes can be found in Data rate calculations on page 4-99, where data
rate calculations plots are given for each available modulation mode.
Link Symmetry
A ratio that expresses the division between transmit and receive time in the TDD
frame. 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.
NOTE
Link Symmetry is configured at the master ODU only. The appropriate
matching Link Symmetry is set at the slave ODU automatically. For example,
if Link Symmetry is configured as “2 to 1” at the master ODU, then the slave
ODU will be set automatically as “1 to 2”. In this example, the master-slave
direction has double the capacity of the slave-master direction.

Maximum Transmit Power
This specifies the maximum transmit power in dBm of the system. It is country
dependent and although the user can change this in 1dB steps, it will be limited to that
country’s regulations.
NOTE
UK requirement: In the UK there is a legal requirement to provide a
minimum of 19 dB of transmit power control range. When the equipment is
operating with a UK License Key, an additional facility is provided on the
configuration page that allows the transmitted power to be reduced by 19 dB
compared to the maximum allowed with a simple single step control..
Why Reduce Transmit Power? If the link losses are low and the link data
rate and availability targets are being easily achieved, the transmitted power
level may be reduced with a consequent benefit to other users of the band,
such as fixed satellite links.

Spectrum management
Spectrum Management Selection is the PTP 600 Series feature that 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.
Wireless channels
The PTP 600 Series operates using a set of predefined overlapping channels. There are
a different number of channels, depending on the raster mode selected. Each channel
occupies 30 MHz, 20 MHz, 15 MHz, 10 MHz or 5 MHz of wireless spectrum and is
offset in center frequency from its neighboring channel by 10 MHz or 6 MHz. It is
important to note that adjacent channels on the Spectrum management display have a
10 MHz or 6 MHz overlap to the adjacent channel.
The default channelization can be modified by varying the lower center frequency
attribute in the installation wizard, as described in Installation step 2 - wireless
configuration on page 6-59.
Spectrum management measurements
The PTP 600 Series 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. It is important to note that 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.
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.

User Guide: PTP 600 Series
Configuring the PTP 600
The analysis produces three key metrics for each channel:
Peak of Means
This is the largest mean interference measurement encountered during the
quantization period. The peak of means is similar to the peak of peaks and is useful for
detecting slightly longer duration spikes in the interference environment.
99.9% Percentile of the Means
This is the value of mean interference measurement which 99.9% of all mean
measurements fall below, during the quantization period. The 99.9% percentile metric
is useful for detecting short duration repetitive interference that by its very nature has
a minimal effect of the mean of means.
Mean of Means
This is the arithmetic mean of the measured means during a quantization period. The
mean of means is a coarse measure of signal interference and gives an indication of
the average interference level measured during the quantization period. The metric is
not very good at predicting intermittent interference and is included to show the
spread between the mean of means, the 99.9% percentile and the peak of means.
NOTE
The arithmetic mean is the true power mean and not the mean of the values
expressed in dBm.
Spectrum Management uses the 99.9% percentile as the prime interference
measurement. All subsequent references to interference level refer to this
percentile measurement.
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.

The spectrum management master / slave relationship
The Spectrum Management operates in a master / slave relationship. The master is
assumed to be the link master configured during installation. All Spectrum
Management configuration changes MUST be performed from the master. To enforce
this, the Spectrum Management web page has a different appearance depending if you
are viewing the data from the master or slave.
All configuration changes are applied at the master only. These changes are then
messaged from the master to the slave. Any Spectrum Management configuration
messages received at the slave are stored in non-volatile memory. This enables both
master and slave to keep identical copies of Spectrum Management configuration data
in their non-volatile memories. It is therefore possible to swap master and slave roles
on an active Point-to-Point link without modifying Spectrum Management
configuration.
Figure 6-9 shows an example Spectrum Management webpage as seen from the
master.
Figure 6-10 shows an example Spectrum Management webpage as seen from the
slave. It should be noted that the key configuration attributes are not available on the
slave web page.
NOTE
These examples are for 15 MHz operation; other channel bandwidths are
similar. The width of the vertical green bar represents the channel width.

Spectrum management configuration
The following section describes the user modifiable configuration accessible from the
Spectrum Management webpage (Figure 6-9). It is recommended that the default
values are maintained. If the user believes that the performance of the Spectrum
Management algorithm requires some modifications this should only be done after
consulting the Motorola Point-to-Point distributor or one of the system field support
engineers.
The Spectrum Management page contains the following fields:
Page Refresh Period
The page refreshes automatically according to the setting entered here (in seconds).
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 (not configurable)
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.
Interference Threshold
Spectrum Management uses the interference threshold to perform instantaneous
channel hops. If the measured interference on a channel exceeds the specified
threshold, then i-DFS will instruct the wireless to immediately move to a better
channel. If a better channel cannot be found the PTP 600 Series will continue to use
the current active channel. (Default –85 dBm).
Channel Bandwidth (not configurable)
This shows the value of the variable channel bandwidth selected.
Barring channels
Channels can only be barred / unbarred by the system administrator from the master
Spectrum Management web page. The barring / unbarring operations are disabled on
the slave web page. If an attempt to bar / unbar a channel is made at the slave, a
warning dialog is generated.
Barring/Unbarring of channels is performed by clicking the appropriate channel on the
local or peer channel spectrum plots on the master web page. Each bar / unbar
attempt will be proceeded by a confirmation dialog. It should be noted that the
channel bar will take effect immediately and is not related to the measurement
quantization period.

Spectrum management (fixed frequency)
The PTP 600 Series software allows a user to optionally fix transmit and receive
frequencies for a wireless link. Once configured, the spectrum management software
will not attempt to move the wireless link to a channel with lower co and adjacent
channel interference. Therefore this mode of operation is only recommended for
deployments where the installer has a good understanding the prevailing interference
environment. (See Installation step 2 - wireless configuration on page 6-59). Care must
also be taken to ensure that the frequency allocations at each end of the link are
compatible. To help the user when identifying the mode of operation Spectrum
Management uses two visual cues. See Figure 6-14. The main page title identifies the
mode of operation using the “Fixed Frequency Mode” postfix and the selected
channels are identified by a red capital ‘F’.

telecoms signals.
A "Wireless" loopback sends the telecoms data received across the wireless link back
across the link on the same Telecom channel. The link may be checked using, for
example, a Bit Error Rate Tester to ensure that no errors are detected.
A typical T1 or E1 installation might include a "Copper" loopback on the local unit

CAUTION
The factory default configuration is limited in range to 40 Km (25 miles). If
you wish to install a wireless link with a range of > 40 Km (> 25 miles) and
< 200 Km (< 124 miles) or < 5 Km (< 3 miles) you must follow Manual
configuration on page 6-52.
The factory default configuration is set to Region 1. Region 1 allows the PTP
600 Series a maximum transmit power of 25 dBm. If the local regulatory
regime limits the maximum transmit power (EIRP) to less than 25 dBm, you
should obtain a new license key containing the correct region code from
your local distributor or direct from Motorola. Alternatively in the short
term, you should reduce the maximum transmit power by following the
procedures in Manual configuration on page 6-52.
Manual configuration
If the installer / system administrator wishes, they may modify the default installation
configuration. If only the IP addresses (network configuration) are incorrect it is
recommended that the values are changed via the configuration menu, as described in
LAN configuration on page 6-42.
NOTE
If any other parameters (for example region code) require modification, then
it is recommended that the system administrator use the Installation Wizard.
The PTP 600 Series operational software requires a license key (Figure 6-26) to enable
the wireless bridging capability and programs region code specific parameters in to
the unit.

The Wireless Configuration page contains the following fields:
Access Method
This controls whether the link can be established between a pre-paired Master and
Slave only (‘Link Access’) or between Master and Slave belonging to the same group
(‘Group Access’).
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 600 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

Dual Payload
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 1-20.

Ranging Mode
During installation, the wireless units perform “Automatic Ranging”. The ranging
mode allows the installer to control the behavior of the system’s automatic ranging
algorithms. The default value is 0 to 40 km (0 to 25 miles). If the installer is required
to install a link of greater than 40 km (25 miles) then the ranging mode attribute
MUST be configured to ‘0 to 100km’ (0 to 62 miles) or ‘0 to 200km’ (0 to 124 miles)
mode depending on the range of the link.
NOTE
If preferred, range functions can be configured to operate in miles, as described
in Properties on page 6-131.
Target Range
Installers that know the range between the two wireless units to within ± 1 km can use
the target range mode. The main advantage of the target range mode is that it reduces
the time taken by the units to range. To use the target range mode the installer MUST
select Target Range as the ranging mode and enter the approximate range in km in
the Target range data entry field at both ends of the link.
Platform Variant
Chooses between an integrated unit or a connectorized unit that requires an external
antenna.
Frequency Band
Only displayed for the PTP 25600 frequency variant, which operates in one of three
bands as described in Variable channel bandwidth operation on page 2-5:
Lower: 2496 MHz to 2568 MHz
Middle: 2572 MHz to 2614 MHz

Link Symmetry
(Master only) Values of "Adaptive", "2 to 1", "1 to 1" and "1 to 2" 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 “2 to 1” at the master ODU, then the slave
ODU will be set automatically as “1 to 2”. In this example, the master-slave direction
has double the capacity of the slave-master direction.
NOTE
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.
"2 to 1" and "1 to 2" are not supported in 5 MHz channel bandwidth.
“2 to 1” and “1 to 2” are not supported when E1/T1 services are enabled.
Spectrum Management Control
Is used to configure the PTP 600 Series Spectrum Management features, see
Spectrum management on page 6-22 for more details. In regions that do not mandate
DFS (Radar Detection), the Spectrum Management Control options are “i-DFS” and
“Fixed Frequency”. In regions that mandate DFS (Radar Detection), the Spectrum
Management Control options are “DFS” and “DFS with i-DFS”.
The Spectrum Management Control is disabled if the regulatory requirement is fixed
frequency only (for example if the frequency variant is PTP 25600).
Lower Center Frequency
Not displayed for the PTP 49600. Not displayed when Spectrum Management Control
is set to “Fixed Frequency”. The software for the PTP 600 Series 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.

Chapter 6 Operation
NOTE
Because the 4.9 GHz spectrum is restricted by license, the Lower Center
Frequency is fixed for the PTP 49600 and is therefore not displayed.
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
This is only displayed when Spectrum Management Control is set to “Fixed
Frequency”. The software for the PTP 600 Series 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 6-32 shows an example of the fixed frequency configuration for a 30 MHz
channel bandwidth. In this example, the Fixed Transmit Frequency is set to 4436 MHz
and the Fixed Receive Frequency is set to 4436 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 10 MHz, both the Fixed Transmit and Receive
Frequencies must be a multiple of 10 MHz from the Lower Center Frequency (4426 =
4416 + 10 MHz) and (4486 = 4416 + 10 MHz × 7).
NOTE
A raster limits the selection of the Rx frequency based upon the setting of
the Tx frequency.

Configuring SNMP notifications
Perform this task to enable the PTP 600 to generate Simple Network Management
Protocol (SNMP) traps.
If SNMP is enabled, then the PTP 600 generates SNMP traps when certain events
occur, and sends the traps to the network SNMP management agent, which notifies
the system administrator.
To configure SNMP notifications, proceed as follows:

Diagnostics plotter
To further enhance the diagnostic capabilities of the PTP 600 Series, the storage of
link performance histograms has been extended to 31. To optimize RAM (volatile
memory) usage a cascading histogram approach has been adopted. The root histogram
is identical to the histograms in earlier releases of the software, that is data is stored
for one hour at a resolution of one second. Previously, the histograms were simple
cyclic buffers which never stored more that the last one hour of data. The new
cascading histogram approach daisy chains multiple histograms together. When the
first histogram fills up the overflow from the first is used as an input to the next
histogram in line. To optimize memory utilization, a statistical analysis is performed on
the overflow to reduce the amount of data to be stored. In the case of the PTP 600
Series the cascading histograms are defined as:
•
Histogram 1: 1 hour at a resolution of 1 second
•
Histogram 2: 24 hours at a resolution of 1 minute
•
Histogram 3: 30 Days at a resolution of 1 hour
For example, when histogram 1 fills up and starts to overflow the first minute of
overflow is analyzed and the maximum, minimum and mean over that minute are
computed and inserted into histogram 2. When histogram 2 fills up and starts to
overflow the first hour of overflow is analyzed and the maximum, minimum and mean
over that hour is computed and inserted into histogram 3. When histogram 3 starts to
overflow, the overflow data is simply discarded.

When the link end hardware (PIDU Plus, LPU, ODU and cabling) has been installed,
test it by following this procedure:
Procedure 7-2 Testing link end hardware
Apply mains or battery power to the PIDU Plus. The green Power LED should
illuminate continuously.
After 45 seconds, the orange Ethernet LED should be observed starting with

Connect the CAT5e cable from the LAN port of the PIDU Plus to the network.
The Ethernet LED should blink randomly as traffic passes through.
If the Power and Ethernet LEDs do not illuminate correctly, test the link end
as described in the flowchart (Figure 7-1) and detailed test procedures that
follow.
If a UltraSync GPS synchronization unit has been installed, but one or more of
its status LEDs are not illuminated, refer to Test UltraSync GPS receiver on

Motorola.
If all tests so far have succeeded, proceed as follows:
Procedure 7-7 Other power tests
Reconnect the ODU cable to the PIDU Plus.
Measure the current with an ammeter placed across the two jumper pins. It
should be in the range 300 mA to 1 A with the ODU connected.
If the ammeter reading is too high, the ODU may be drawing too much power,
or the ODU may be short-circuited. Report a suspected ODU fault to Motorola.
If the ammeter reading is too low, the PIDU Plus may be supplying too little
power. Report a suspected PIDU Plus fault to Motorola.

Power LED is flashing
If the green Power LED is flashing, proceed as follows:
Procedure 7-8 Power LED is flashing
Remove and examine the cable that connects the PIDU Plus to the LPU or ODU.
Check that pins 4&5 and 7&8 are not crossed with pins 1&2 and 3&6.
Check that the resistance between pins 1&8 is greater than 100K ohms.
If either check fails, replace or repair the cable that connects the PIDU Plus to
the LPU or ODU.
Ethernet LED did not flash 10 times
When the PIDU Plus is connected to the power supply and the green Power LED
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 7-9 Ethernet LED did not flash 10 times
Remove and examine the cable that connects the PIDU Plus to the LPU or ODU.
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.
If an LPU is installed, it can be used to check that power is available on the
cable to the ODU. The connections can be accessed by rotating the LPU lid as
shown in Figure 7-3. The Lid nut only needs to be slacken, do not remove. Test
that point P1 on the LPU PCB corresponds to pin 1 on the RJ45. Repeat for
points P2 to P8. An indication of power on the Ethernet cable is also provided
inside the LPU: the LED PWR1 should illuminate but LED PWR2 should not.
If either test fails, replace or repair the cable that connects the PIDU Plus to the
LPU or ODU.

Status page
The link loss calculation presented on the Status Page of the management interface
has to be modified to allow for the increased antenna gains at each end of the link.
The manufacturing process of the Connectorized 600 Series configures the standard
hardware of the unit for use with external antennas. The installer is prompted, as part
of the installation process, to enter the gain of the external antenna(s) and cable losses
at each end of the link. Peer-to-peer messaging is used to pass the effective antenna
gain to each end of the link so that the link loss calculations can be correctly
computed.

Deployment considerations
Deployment considerations
When to use external antennas
The majority of radio links can be successfully deployed with the PTP 600 Series. It
should only be necessary to use external antennas where the LINKPlanner indicates
marginal performance for a specific link – for example when the link is heavily
obscured by dense woodland on an NLOS link or extremely long LOS links (>80km or
>50 miles) over water.
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.
Link budget
An estimate of the link budget for a specific application can be obtained by using the
Motorola LINKPlanner tool. For more information see the Motorola web site.

Maximum EIRP
Normal EIRP limits
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 (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 (23 + 10 x Log Bandwidth) dBm.
As the PTP 600 has an operating bandwidth from approximately 5 MHz to
approximately 30 MHz, then the maximum allowed EIRP depends on the operating
bandwidth of the radio as shown in Table 8-1.

Calculating EIRP
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
As the actual maximum transmit power can only be adjusted in 1 dB steps, then the
installer or operator must configure the PTP 600 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 8-1 (assuming short feeder cables) are shown in Table 8-2.
NOTE
Table 8-2 has been calculated on the basis of 0.5 dB cable loss and the
highest gain antennas per size of which we are aware. At these operating
frequencies, feeder losses even with short cables are unlikely ever to be
below 0.5 dB for practical installations and cable diameters.

Cable losses (FCC regions only)
The FCC approval for the product is based on tests with a cable loss between the units
of not less than 1.2 dB at 5.8 GHz. The use of lower cable losses would result in the
installation being outside the FCC rules. As an indication, 1.2 dB of cable loss
corresponds to the following cable lengths excluding connector losses (source: Times

Antenna choices
Antenna choices
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 Licenses and region
codes on page 2-3.
FCC regions
In FCC regions, antenna choice is restricted as described in PTP 54600 FCC antenna
restrictions on page 4-64 and PTP 58600 FCC antenna restrictions on page 4-85.
The maximum permitted antenna gain depends upon product variant and channel
bandwidth, as specified in PTP 49600 radio system specifications on page 4-47 and
Regulatory issues with connectorized units on page 8-10.

Chapter 8 Connectorized PTP 600 series
Installing connectorized bridges
The section covers the generic installation instructions for the Connectorized versions
of the PTP 600 Series point-to-point wireless Ethernet bridges. The actual installation
procedure will depend on antenna choice, cable choice, required antenna separation
etc.
PTP 54600 FCC antenna restrictions on page 4-64 and PTP 58600 FCC antenna
restrictions on page 4-85 show a wide variety of antennas that can be used with the
Connectorized PTP 600 Series.
Cables and connectors
Cables should be selected using the above criteria. However it should be noted that a
cable of a type similar to LMR400 is a lot more difficult to handle and route than a
cable of a type similar to LMR100.
Motorola recommends the use of weatherproof connectors, preferably ones that come
supplied with adhesive lined heat shrink sleeve that is fitted over the cable/connector
interface.
The connectors required at the Connectorized PTP 600 Series end of the antenna
cables are N-Type Male.
The connectors required at the antenna end of the antenna cables is dependant on the
antenna type chosen.
Tools
The tools required for mounting a Connectorized PTP 600 Series unit are the same as
those required for an Integrated 600 Series detailed in Preparing for site installation
on page 5-7. The tools required for mounting the antennas are specific to the antenna
chosen. The installer should refer to the antenna manufacturer’s instructions.

Miscellaneous supplies
The following miscellaneous supplies will be required:
•
Cable ties, cable cleats – for securing cables
•
Self-amalgamating tape – to weatherproof the RF connectors
•
PVC tape – for additional protection of the RF connectors and securing cables
Mounting the connectorized PTP 600
A Connectorized PTP 600 Series is shipped with the same bracket as supplied with an
Integrated unit. Details on the use of this bracket can be found in Mounting brackets
on page 1-7. The PTP 600 Series should be mounted in a position that gives it
maximum protection from the elements, but still allows easy access for making off the
various connections and applying the recommended weatherproofing.
When using dual polar antennas the Connectorized PTP 600 Series should be mounted
in such a position as to minimize the cable length, keeping losses to a minimum, taking
into account the minimum cable lengths required by the FCC regulations, see PTP
58600 FCC antenna restrictions on page 4-85.
When using separate antennas the Connectorized PTP 600 Series should be mounted
in such a position as to minimize both cable runs between the unit and the antennas. It
is not necessary to mount the Connectorized PTP 600 Series at the mid point between
the antennas.
Mounting the antennas
The Antennas should be mounted according to the manufacturer’s instructions. Actual
antenna position will depend on the available mounting positions and link
requirements. It may be necessary to mount the antennas 20m apart or at a certain
distance from the ground to get the desired results.

Alignment process
When aligning antennas deployed with a Connectorized PTP 600 Series unit it may not
be possible to hear the alignment tone emanating from the unit. In this case it may be
necessary for a second installer to assist in the operation. Alternatively, it may be
possible to extend the tube on the supplied stethoscope to give a longer reach.
NOTE
Fine antenna alignment can sometimes be achieved by tightening and loosening
the bolts on either side of the antenna mounting bracket, rather than trying to
turn the whole bracket on the mounting pole.
Aligning dual polar antennas
The process for aligning a dual polar antenna is the same as aligning an Integrated
unit with an integrated antenna. This procedure is detailed in Using the ODU

Chapter 8 Connectorized PTP 600 series
Completing the installation
The installation should be completed by checking all mounting nuts bolts and screws,
securing all cables and weatherproofing the installation.
CAUTION
Finally tightening the antenna mountings may cause the antenna alignment
to be altered, due to distortion in the mounting bracket caused by action of
tightening. It is recommended that the installation tone be left turned on
(armed) during this process so that any movement can be noticed and
counteracted by tightening the other side of the bracket.
Antenna cable fixing
Cables should be secured in place using cable ties, cleats or PVC tape. Care should be
taken to ensure that no undue strain is placed on the connectors on both the
Connectorized PTP 600 Series and the Antennas and also to ensure that the cables do
not flap in the wind. Flapping cables are prone to damage and induce unwanted
vibrations in the mast to which the units are attached.

Antenna connection weatherproofing
Where a cable connects to an antenna or unit from above, a drip loop should be left to
ensure that water is not constantly channeled towards the connector.
Figure 8-7 Forming a drip loop
All joints should be weatherproofed using self-amalgamating tape. It is recommended
that a layer of PVC tape be placed over the self-amalgamating tape to protect the joint
while the self-amalgamating tape cures and gives additional protection. Figure 8-8
shows this diagrammatically for the PTP 600 Series end of the antenna cables. If the
antenna manufacturer has not supplied guidance on this matter, the same technique
should be employed at the antenna end of the cable.

Chapter 9 FAQs
General FAQs
Can I source and use my own PoE adaptor with the PTP 600 Series? No. The
PTP 600 Series uses a non-standard PoE configuration. Failure to use the Motorola
supplied Power Indoor Unit could result in equipment damage and will invalidate the
safety certification and may cause a safety hazard.
Why has Motorola launched the PTP 600 Series? The PTP 600 Series is the first
product to feature Multiple-Input Multiple-Output (MIMO). The PTP 600 Series
solutions allow wireless connections of up to 200km (124 miles) in near line-of-sight
conditions and up to 10km (6 miles) in deep non-line-of-sight conditions.
What is Multiple-Input Multiple-Output (MIMO)? The PTP 600 Series radiates
multiple beams from the antenna - the effect of which is to significantly protect against
fading and to radically 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
best in class link budget, there is a significant improvement to the probability of a
robust connection over a non-line-of-sight path.
What do you mean by “non-line-of-sight”? A wireless connection between two
points without optical line-of-sight, that is, with obstructions between the antennas the
transmitted signal is still able to reach the receiver and produce a good quality link.
What else is special about the PTP 600 Series ? There are many special features
built-in to the hardware of the PTP 600 Series. The product offers the highest system
gain in its class through high sensitivity antennas for improved signal recovery. It also
features a radio system that operates on ultra fast digital signal processors but is
controlled by firmware giving the ability to download new firmware when
enhancements become available. The PTP 600 Series has a built-in web server for
advanced management capabilities including detailed radio signal diagnosis.
In which frequency bands does the PTP 600 Series operate? The Motorola pointto-point 600 Series operates in the licensed bands 2.5 GHz, 4.5 GHz, 4.8 GHz and 4.9
GHz, and in the unlicensed bands 5.4 GHz (ETSI Band B), 5.8 GHz (ETSI Band C and
FCC ISM band) and 5.9 GHz. Users must ensure that the PTP 600 Series complies with
local operating regulations.
Why does the PTP 600 Series operate in the 5GHz band? The 5 GHz band offers
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.

General FAQs
Is the PTP 600 Series an 802.11a device? No, although similar, the PTP 600 Series
uses different encoding and radio transmission systems from 802.11a. In areas where
802.11a systems are operating, the PTP 600 Series will detect the 802.11a radio
signals and choose a clear channel away from any interference.
How much power does the PTP 600 Series transmit? At all times the PTP 600
Series operates within country / region specific regulations for radio power emissions.
In addition, the PTP 600 Series uses a technique known as Transmit Power Control
(TPC) to ensure that it only transmits sufficient radio power such that the other
antenna can receive a high quality signal.
How does the PTP 600 Series avoid interference from other devices nearby? At
initialization, the PTP 600 Series monitors the available frequency channels to find a
channel that is clear of interference. In operation 600 Series continuously monitors the
spectrum to ensure it is operating on the cleanest channel.
How does the PTP 600 Series integrate into my data network? The PTP 600
Series acts as a transparent bridge between two segments of your network. In this
sense, it can be treated like a virtual wired connection between the two buildings. The
PTP 600 Series forwards 802.3 Ethernet packets destined for the other part of the
network and filters packets it does not need to forward. The system is transparent to
higher-level management systems such as VLANs and Spanning Tree.
How does the PTP 600 Series provide security for data traffic? The PTP 600
Series has a range of security features. At installation time each link must be
programmed with the serial ID of its partner. The two ends of the link will only
communicate with one another, eliminating any chance of "man in the middle" attacks.
Over the air security is achieved through a proprietary scrambling mechanism that
cannot be disabled, spoofed or snooped by commercial tools.
Can I use Apple Macintosh OS X to control and monitor my 600 Series? Yes, but
there are some restrictions. Mozilla 1.6 or higher is recommended.

Link encryption FAQs
Encryption data entry fields are not available
Check that the correct license key has been inserted into the unit. The current license
key is displayed on the ‘License Key’ data entry page.
Link fails to bridge packets after enabling link encryption
If the wireless link status on the status web page indicates that the link is ‘Searching’,
and you can browse to the local end of the link but not to the remote end, then check
that the same encryption algorithm and key have been entered at both ends of the link.
Failure to enter the same algorithm and key will result in received packets not being
decrypted correctly.
Loss of AES following downgrade
When downgrading (using Recovery software image 05-01 onwards) to an earlier
version of software that does not support AES, the unit will indicate that the region
code is invalid. The user will be required to re-install correct software (supplied when
AES key was activated) and reboot the unit.
