Compliance
General
Changes or modifications not expressly approved by Motorola could void the user’s authority to
operate the system.
NOTE: 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 is 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.
3
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
device1, 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.
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/PIDU 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 gen-
erally. 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 500 Series Bridge is controlled by the use of Region-specific
License Keys.
The following examples show how the regulatory limits apply in some specific countries at the
current time. Operators should note that regulations are subject to change.
Contact your supplier/installer to ensure that your product is set for the correct License Key for
your Country/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. Notes below the tables indicate
countries where registration of the link is currently mandatory.

2 Avoiding Hazards
2.1 Preventing Overexposure to RF Energy
Caution To protect from overexposure to RF energy, install the radios for the 500 family of PTP
wireless solutions so as to provide and maintain the minimum separation distances from all persons
as shown in Table 3.
When the system is operational, avoid standing directly in front of the antenna. Strong RF fields
are present when the transmitter is on. The Outdoor Unit (ODU) must not be deployed in a
location where it is possible for people to stand or walk inadvertently in front of the antenna.
At these and greater separation distances, the power density from the RF field is below generally
accepted limits for the general population.
Note These are conservative distances that include compliance margins.
2.1.1 Calculations for Separation Distances and Power Compliance Margins
Limits and guidelines for RF exposure come from:
•US FCC limits for the general population. See the FCC web site at http://www.fcc.gov,
and the policies, guidelines, and requirements in Part 1 of Title 47 of the Code of Federal
Regulations, as well as the guidelines and suggestions for evaluating compliance in FCC OET
Bulletin 65.
•Health Canada limits for the general population.
See the Health Canada web site at
http://www.hc-sc.gc.ca/ewh-semt/pubs/radiation/99ehd-dhm237/limits-limites_e.html
and Safety Code 6.
•ICNIRP (International Commission on Non-Ionizing Radiation Protection) guidelines for the
general public. See the ICNIRP web site at http://www.icnirp.de/ and Guidelines for
Limiting Exposure to Time-Varying Electric, Magnetic, and Electromagnetic Fields.
The applicable power density exposure limits from the documents referenced above are:
•6 W/m2 for RF energy in the 900-MHz frequency band in the US and Canada.
•10 W/m2 for RF energy in the 2.4-, 5.2-, 5.4-, and 5.8-GHz frequency bands.
Peak power density in the far field of a radio frequency point source is calculated as follows:
S=P.G
4πd2(1)
Where:-
S= power density W/m2
P= Maximum Average transmit power capability of the radio W
G= total Tx gain as a factor, converted from dB
d= distance from point source m

transmit burst subject to allowance for source-based time-averaging.
2. At 5.4GHz the product is generally to a fixed EIRP which can be achieved with the Integrated
Antenna. If there are no EIRP limits, use the distance calculations for 5.8GHz.
3. At 5.8GHz, for antennas between 0.6m (2ft) and 1.8m (6ft), alter the distance proportionally
to the antenna gain

3.3 Product Description
This User Manual is specifically written for the 500 family of point-to-point broadband wireless
solutions. The PTP 500 Series Bridge has been developed to provide Point-to-Point data connec-
tivity via a 5.4 GHz or 5.8 GHz wireless Ethernet bridge operating at broadband data rates. The
PTP 500 Series 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.
Figure 1 Typical PTP 500 Series Bridge Deployment
The PTP 500 Series Bridge offers 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. These technologies enable the PTP 500 Series Bridge to drive through
foliage and around buildings to such an extent that almost universal coverage can be expected at
short range.
A PTP 500 Series Bridge system consists of a pair of identical devices that are deployed one at
each end of the link. At installation, the user sets up one unit as the Master and the other as the
Slave. Either unit can be configured as Master or Slave.
Each end of the link consists of:
•An integrated (or connectorized - see section 13) outdoor transceiver unit containing all the
radio and networking electronics hereafter referred to as the Outdoor Unit (ODU).
•An indoor connection box containing a mains power supply, status indicators and network
connection port. Hereafter referred to as the Power Indoor Unit Plus (PIDU Plus).
Getting Started
23
A pair of units is normally supplied pre-configured as a link.
The network connection to a PTP 500 Series Bridge is made via a 100BaseT Ethernet connection.
Power is provided to the ODU over the 100BaseT Ethernet connection using a patented non-
standard powering technique.
Power is fed into the PTP 500 Series Bridge PIDU Plus from the mains via a standard “figure of
eight” mains plug. Connection between the ODU and PIDU Plus is made using standard CAT5e
outdoor UV resistant cable. Connection between the PIDU Plus and the Network Equipment is
made using standard CAT5e cable.

3.3.1 The Outdoor Unit (ODU)
The ODU is a self-contained unit. It houses both radio and networking electronics. The ODU
for the PTP 500 Series Bridge should only be deployed using the supplied PTP 500 Series Bridge
PIDU Plus. Figure 2 shows an installation example of a PTP 500 Series ODU with a Motorola
lightning protection unit (PTP-LPU).

3.3.2 PIDU Plus – PTP 500 Series Bridge
The PTP 500 Series Bridge PIDU Plus is used to generate the ODU supply voltage from the
mains supply and inject this supply voltage into the 1000BaseT Ethernet connection to the ODU.
Connection uses a CAT5e cable using standard RJ45 wiring.
CAUTION: Care should be taken not to connect equipment other than an ODU for the PTP 500
Series Bridge to a PIDU Plus ODU port as equipment damage may occur. The PTP 500 Series
Bridge PIDU Plus is not interchangeable with the PTP 400 Series PIDU Plus but can be used
with the PTP 600 Series.
Figure 3 Power Indoor Unit
(PIDU Plus) – PTP 500 Series
The front panel contains indicators showing the status of the power and Ethernet connections.
The power indicator is illuminated when the PIDU Plus is receiving mains power.
The Ethernet indicator normally illuminates when the Ethernet link is working, flashing when
there is Ethernet activity. The fact that it lights also indicates that the ODU is powered. At
power up the LED will flash 10 times to indicate that a correct start up sequence has occurred.
See Section 10 “Fault Finding” for further fault finding information.
At the bottom of the PIDU Plus is an entry point for the PIDU Plus to ODU cable, the 100BaseT
Ethernet network port and the Recovery switch.
Figure 4 PIDU Plus Recovery Switch Location
Getting Started
26
The Recovery switch is used to recover the unit from configuration errors or software image corrup-
tion. To put a PTP 500 Series Bridge into Recovery mode the Recovery switch should be pressed
then the power applied. The Recovery switch should be kept pressed for at least 30 seconds after
the power has been applied. Full instruction on the recovery mode can be found in Section 9
“Recovery Mode”.
A simple reboot can be performed by removing and re-applying the mains power to the PTP 500
Series Bridge PIDU Plus.
On the left hand side of the PIDU Plus, 48V DC input and output connections can be found. These
are used to power the PTP 500 Series Bridge from an external DC source or to provide a level
of power supply redundancy, as shown in Section 3.3.3 “Redundancy and Alternate Powering
Configurations”.
WARNING: When using alternate DC supplies 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 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/UL6090,
Clause 2.5, Limited Power (The Energy Hazard Limit is 240VA)
Also on the left hand side of the PTP 500 Series Bridge PIDU Plus, connectors and jumpers can
be found that allow the remote connection of power LED, Ethernet LED and Recovery switch.
The connection instructions can be found in Section 3.3.4 “Remote LEDs and Recovery Switch”.
The input supply range for the 500 Series PIDU Plus is 90V-264V AC, 47-63Hz. Mains connection
to the PIDU Plus is made using a standard “figure of eight” mains lead as shown in Figure 5.

3.3.4 Remote LEDs and Recovery Switch
The PTP 500 Series Bridge PIDU Plus provides a facility to connect remote LEDs and Recovery
switch allowing the PIDU Plus to be mounted inside an enclosure. At the left hand end of the PIDU
Plus under the ODU connection cover can be found a PCB header and three jumpers. Jumpers
J906 and J907 should be removed and connection to the remote LEDs and Recovery switch made
to J908 as shown in Figure 10.
Figure 10 Remote LED and Recovery Switch Wiring
3.3.5 Cables and connectors
The cable used to connect the PTP 500 Series Bridge PIDU Plus to the ODU can be any standard
CAT5e type provided that it is suitable for outdoor deployment. Motorola recommends that cables
to the specification below be used:
Cable: Superior Essex BBDGE CAT 5e
Connector Type: Tyco, 5-558530-1
Gland: Motorola WB1811
Getting Started
30
Caution: Failure to use the recommended (or equivalent) standard of cable may invalidate the
system’s safety certification.
The cable used to connect the PTP 500 Series Bridge PIDU Plus to the users Network Equipment
can be any standard CAT5e Cable.
The PIDU Plus to ODU and the PIDU Plus to Network Equipment cables may be unscreened
(UTP) or screened (STP). However, unscreened cables reduce the system’s ability to cope with
nearby lightning strikes. If lightning activity is common in the area of deployment, the use of
screened cable is highly recommended. See Section 11 “Lightning Protection”.
The PIDU Plus provides screen continuity between the ODU and Network Equipment connections.
Note:The ODU network connection implements automatic MDI/MDI-X sensing and pair swapping
allowing connection to networking equipment that require cross-over cables (MDI-X networks) or
straight-through cables (MDI Networks).
3.3.6 PTP and Lightning Protection
The PTP 500 Series Bridge PIDU Plus meets the low level static discharge specifications identified
in Section 17 “Specifications”, but does not provide lightning or surge suppression. Installations
will generally require lightning or surge suppression, a separate Ethernet surge suppressor must
be used and appropriately earthed. Suitable surge suppressors can be sourced from your Motorola
Point-to-Point Distributor or Solutions Provider. See Section 11 “Lightning Protection”.
3.3.7 Mounting Brackets
The PTP 500 Series Bridge is supplied with a mounting bracket suitable for mounting the ODU
to a pole of 50mm (2”) to 75mm (3”) in diameter. For more details on mounting, see Section 7
“Installation”.
The bracket allows for adjustment in both azimuth and elevation. The bracket may be split
allowing the pole mount section of the bracket to be mounted to the pole first. This allows the
installer to take the weight of the unit and secure it, one handed, with a single mounting bolt.
The PIDU Plus can either be desk or wall mounted. The preference is wall mounted with the
cables dressed to a cable channel. Wall mounting is achieved by screwing through the mounting
lugs on either side of the unit. Remember to leave space for access to the Recovery button. See
Section 3.3.2 “PIDU Plus – PTP 500 Series Bridge”.
3.3.8 Configuration and Management
Configuration and Management of the PTP 500 Series Bridge is implemented using an inbuilt web
server hosting a number of Configuration and Management web pages. This approach allows Con-
figuration and Management to be carried out on any standard web browsing technology. The PTP
500 Series Bridge can also be managed remotely using the SNMP management protocol. Connec-
tion to the bridge is via the Ethernet connection carrying the bridge network traffic. Connection
to the unit is via a preset IP address. This address can be changed via the Network Interface
Configuration web page. A full explanation of the available web pages and their use can be found
in Section 8 “Web Page Reference”.

Product Architecture
32
4 Product Architecture
The 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 non-line-of-sight (NLOS) aspects of
the product are provided by Multiple-Input Multiple-Output (MIMO), coupled with Orthogonal
Frequency Division Multiplexing (OFDM) modulation.
The PTP 500 Series Bridge has been developed to operate within license exempt frequency bands.
The current product range supports:
•ETSI 5.4 GHz band B (5.470-5.725 GHz)
•ETSI 5.8 GHz band C (5.725-5.850 GHz) and the USA 5 GHz ISM band (5.725-5.850 GHz)
The PTP 500 Series Bridge has been designed to coexist with other users of the band in an
optimal fashion using a combination of Transmit Power Control (TPC), Spectrum Management
functionality and Antenna beam shape.
In order to maintain link availability, the product employs adaptive modulation techniques that
dynamically reduce the data rate in severe or adverse conditions. The PTP 500 series provides
wireless Ethernet bridging between two fixed locations. To be more precise, it forwards Ethernet
frames as a two-port transparent heterogeneous encapsulation bridge, meaning that each bridge
forwards frames between two dissimilar interfaces (Ethernet and wireless), encapsulating Ethernet
MAC frames within a PTP MAC frames for transmission at the wireless interface. A link consisting
of a pair of back to back bridges appears to the data network to be very similar to a standard
two-port Ethernet bridge.
The PTP500 series provides two egress queues in each direction, classifying Ethernet frames into
one of the two prioritised queues based on inspection of the user priority field (802.1p) in the
IEEE802.1Q VLAN tag. Untagged frames receive a default priority. The queuing method is
strict priority. The bridge does not implement any VLAN functions for bridged frames apart from
inspection of the priority field, and consequently the bridge forwards tagged and untagged Ethernet
frames regardless of VLAN ID and without modification of any protocol header fields..
The management function of the PTP 500 Series Bridge is logically equivalent to a separate protocol
stack with virtual point of attachment at the Ethernet interface. This is illustrated in Figure 11.
Product Architecture
33
Figure 11 PTP 500 Series Bridge Layer Diagram
Each unit in the link is manageable through an IP connection. Standard IP protocols are utilized
for all management functions e.g., HP, SNMP, etc. The unit can be configured to use VLAN tags
on the management interfaces.
The PTP 500 Series Bridge is fully software upgradeable. New software images are first downloaded
from the Motorola website http://www.motorola.com/ptp to a convenient computer. The
image is then uploaded to the ODU via the web management page described in Section 8.3.6
“Software Upgrade”. The compressed image is first loaded into RAM and check-summed. If the
compressed image transfer has completed successfully the image is decompressed and written to
flash memory. On completion of this process the unit can be rebooted to use the newly uploaded
image. Should this process fail, the unit will revert to a protected compressed image installed
during manufacturing to allow the unit to be recovered.

•First an operator can utilize the default spectrum management mode i-DFS (intelligent Dy-
namic Frequency Selection). This mode uses the PTP 500 Series Bridge ability to measure the
interference levels in all channels to build up a picture of the interference / noise levels in all
channels. The PTP 500 Series Bridge uses statistical techniques to select the most appropri-
ate transmit and receive channels. i-DFS can be influenced in its channel decision process by
selectively barring channels from use. The use of this functionality is described in detail in
Section 8.3.7 “Spectrum Management”.
•Second, when detailed control of the spectrum allocation is required, it is recommended that
the fixed frequency mode is used to statically allocate transmit and receive channels.

5.2 Region Codes
The PTP 500 Series Bridge uses a system of Region Codes to control the operation of the radio
link. The Region Code is set by a License Key.
Caution: To meet the regulatory requirements of your region you should set the correct Region
Code by obtaining a new License Key from your reseller or distributor.

5.3 Operational Restrictions
5.3.1 Radar Avoidance
Radar Avoidance requires that equipment used in the region:
•Detects interference from other systems and avoids co-channel operation with these systems,
notably radar systems.
•Provide on aggregate a uniform loading of the spectrum across all devices, i.e. Fixed Frequency
operation is not allowed.
•Radar avoidance is not applicable to the PTP54600 product.
To address the primary aims the Spectrum Management algorithm implements a radar detection
function which looks for impulsive interference on the active channel only. If impulsive interference
is detected Spectrum Management will mark the current active channel as having detected radar
and initiate a channel hop to an available channel. The previous active channel will remain in the
radar detected state for thirty minutes after the last impulsive interference pulse was detected.
After the thirty minutes have expired the channel will be returned to the available channel pool.
The radar detection algorithm will always scan the active channel for 60 seconds for radar interfer-
ence before using the channel. This compulsory channel scan will mean that there is a 60 seconds
service outage every time radar is detected and that the installation time is extended by 60 seconds
even if there is found to be no radar on the channel.
NOTE: On system installation or start-up this extends the initial scan time of the Master unit
by 60 seconds. To address the “provide aggregate uniform loading of the spectrum across all
devices” requirement, the channel selection algorithm will choose a channel at random from a list
of available channels. The channel selection algorithm is initiated at link initialization and when
radar interference is detected.
Note that 5.4 GHz and 5.8 GHz are different products.

5.3.2 RTTT Avoidance and Other Channel Use Restrictions
Where regulatory restrictions apply to certain channels these channels are barred. The user should
note that the number of channels barred is dependent on the channel raster selected. For example
see the effect of the UK RTTT channel restrictions in Figure 12. Barred channels are indicated
by a “No Entry” symbol displayed on the “Spectrum Management” web page, see Section 8.3.9
“Spectrum Management Control - With Operational Restrictions”.
NOTE: “Radar Avoidance Enabled” is only valid with 30 MHz channel bandwidth.

raster is set to even center frequencies. See Figure 14.
5.6.2 5.8 GHz 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 PTP 500 Series Bridge solution reduces the power when operating at
the edge channels. The amount of reduction, if any, is dependent on the region code of the region
of operation. This currently only affects systems configured with Region Code 1. The power
reduction in the edge channels for 15 MHz is presented in Table 6 (for region code 1 ONLY).

5.7 Distance
The PTP 500 Series Bridge will operate at ranges from 100 m (330 ft) to 200 km (124 miles), within
3 modes: 0-40km (0-25 miles), 0-100km (0-62 miles) and 0-200km (0-124 miles). Operation of the
system will depend on obstacles in the path between the units. Operation at 40 km (25 miles) or
above will require a near line-of-sight path. Operation at 100m (330 ft) could 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. This subject is covered in
more detail in Section 6.1.3 “Path Loss Considerations”.
5.8 Networking Information
The PTP 500 Series Bridge operates as a transparent Ethernet bridge. Each unit requires an IP
address. This IP address is for management purposes only and it plays no part in the operation
of the system. IP addresses are assigned during initial configuration as described in Section 7.2
“Installation Procedure”.
5.9 Lightning Protection and regulations
The amount of lightning protection is dependent on regulatory requirements and the end user
requirements. The standard ODU for the PTP 500 Series Bridge is fitted with surge limiting
circuits and other features to minimize the risk of damage due to nearby lightning strikes. These
standard features may require some additional equipment to be configured as part of the system
installation to be fully effective. Motorola recommends the use of screened cable and Lightning
Protection units to protect connected equipment from nearby strikes.
NOTE: The PTP 500 Series Bridge is not designed to survive direct lightning strikes. For this
reason the unit should not be installed as the highest point in a localized area, unless specific
precautions are taken. See Section 11 “Lightning Protection”.
5.10 Electrical Requirements
The PTP 500 Series Bridge requires one mains supply outlet at each end of the link to plug in the
PIDU Plus units (Section 3.3.2 “PIDU Plus – PTP 500 Series Bridge”).
Site Planning
42
6 Site Planning
6.1 Site Selection Criteria
The following are guidelines for selecting the installation location of the ODU and PIDU Plus for
a PTP 500 Series Bridge.
6.1.1 ODU Site Selection
When selecting a site for the ODU the following should be taken into consideration:
•It is not possible for people to stand or walk inadvertently in front of the antenna
•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
•Distance from the ODU and connected Network equipment (Maximum cable run from the ODU
to the connected equipment is 100m [330 ft])
•Distance from the PIDU Plus to the ODU (Maximum cable run from the PIDU Plus to the
ODU is 300m [990 ft] when using the Fiber interface)
6.1.2 PTP 500 Series Bridge PIDU Plus Site Selection
When selecting a site for the PIDU Plus the following should be taken into consideration:
•Availability of a mains electricity supply
•Accessibility for viewing status indicators and pressing Recovery switch.
6.1.3 Path Loss Considerations
The path loss is the amount of attenuation the radio signal undergoes between the two ends of the
link. 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).
Lfree_space +Lexcess +Lfade +Lseasonal <L
capability (3)
Where
Lfree_space = Free Space Path Loss dB
Lexcess = Excess Path Loss dB
Lfade = Fade Margin Required dB
Lseasonal = Seasonal Fading dB
Lcapability = Equipment Capability dB
Site Planning
43
6.1.4 Definitions
The equipment capability is given in Table 7,Table 9 (IP Mode) and Table ??,Table 10 (TDM
Mode). Each table gives Link Loss Output Power and System Thresholds for PTP 500 Series
Bridge in all modulation modes for the channel bandwidth 15 MHz. Adaptive Modulation will
ensure that the highest throughput that can be achieved instantaneously will be obtained taking
account of propagation and interference. The calculation of Equation 3 needs to be performed
to judge whether a particular link can be installed. 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.
Sensitivity: Sensitivity is defined as the combined receive input signal level on both horizontal
and vertical inputs that produces a Null Bit Error Ratio of 3x10-7.
Output Power: The output power is for a centre channel in Region 1. The output power will be
reduced on the edge channels and may vary if different region codes are selected.
AMOD Threshold: The AMOD threshold is 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 centre channel
output power. The figures assume integral antennas with 23dBi (5.8 GHz and 5.4 GHz) gain are
used.

7.5 Legal Disclaimer
IN NO EVENT SHALL MOTOROLA, INC. BE LIABLE FOR ANY INJURY TO ANY PERSONS
OR ANY DAMAGE CAUSED DURING THE INSTALLATION OF THE MOTOROLA PTP 500
SERIES PRODUCT.
7.6 Mounting the ODUs
The ODU mounting bracket is designed to ease installation by fixing the bracket to a pole and
then bringing the ODU into position using a single bolt fixing. The ODU should be mounted using
the following steps ensuring that the cable entry is at the bottom.
The ODU mounting bracket is designed to work with poles with diameters in the range 50mm (2”)
to 75mm (3”).
Step 1: Mount the
bracket to the pole.
Step 2: Mate the unit to
the bracket together and
tighten the nut and bolt.
Pole diameters of 25mm (1”) to 50mm (2”) can be accommodated by inverting the back of the
bracket as shown in Figure 15.
Figure 15 Mounting to pole diameters
25mm (1”) to 50mm (2”)
When adjustment is complete tighten all bolts to 14Nm (11lb ft).
CAUTION: Do not over tighten the bolts as bracket failure may occur.
Installation
48
The enclosure and mounting brackets of the PTP 500 Series Bridge product range are capable of
withstanding wind speeds up to 151mph (242kph). The installer should ensure that the structure
the bridge is fixed to is also capable of withstanding the prevalent wind speeds and loads. See
Section 12 "Wind Loading".
The integral safety loop should be used both for hoisting the ODU up a mast or building and into
position, and also as a fixing point to secure a permanent safety lanyard from the tower/building
to the ODU in case of mounting failure.
Figure 16 Integral Safety Loop
The length of the safety lanyard must not exceed 1m (approx 3 ft) in length. The lanyard should
be made from a material that does not degrade in an outdoor environment.
The safety lanyard must be fixed to a separate fixing point that is not part of the direct mounting
system for the ODU.
7.7 Connecting Up
7.7.1 Preparing the PIDU Plus To ODU Cable
NOTE: 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, i.e., when using the PTP 500 Series Bridge Optical Interface.
Installation
49
The cable should be assembled as shown in Figure 17:
Figure 17 Correct Cable Preparation for the Recommended Cable
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 use a cable gland.
Installation
50
Figure 18 shows a completed ODU to PIDU Plus cable.
Figure 18 Completed ODU Connector
CAUTION: Do not over tighten the glands as the internal seal and structure may be damaged.
See Figure 19 for an example of an over tightened cable gland.
Figure 19 Warning Not To Over
tighten Cable Gland
7.7.2 Making the Connections at the ODU
Looking at the back of the unit with the cable entry at the bottom, the PTP 500 Series Bridge

7.7.3 Making the PTP 500 Series Bridge PIDU Plus Connection At The ODU
The following procedure describes how connection is made at the ODU. It is often easier to carry
out this procedure on the ground or a suitable surface prior to mounting the ODU.
Ensure that no power is connected to the PIDU Plus or present on the cable before connecting the
ODU.
Step 1: Assemble the cable
as described in 5.7.1 above
Step 2: Insert the RJ45 connector making
sure that the locking tab snaps home
Step 3: Screw in the body of the
weather proofing gland and tighten
Step 4: Screw on the clamping nut and tighten
(Do not over tighten – see Figure 19)
Figure 21 Connecting the PIDU+ to the ODU
Installation
52
Should it be necessary to disconnect the PIDU Plus to ODU cable at the ODU, this can be
achieved by removing the weather proofing gland and depressing the RJ45 locking tab with a
small screwdriver as shown below:
Figure 22 Disconnecting the ODU
CAUTION: Ensure that power is removed from the system at the PIDU Plus to prevent damage
to the ODU while making or breaking the connection.
7.7.4 Routing the Cable
After connecting the cable to the ODU it can be routed and secured using standard cable routing
and securing techniques. When the cable is in place it can then be cut to the desired length at the
PIDU Plus prior to connection to the PIDU Plus
7.7.5 Fitting a Lightning Protection Unit
If you have opted to fit a Lightning Protection unit, this should be installed by following the
manufacturer’s instruction. For recommended types see Section 11 "Lightning Protection”
7.7.6 Grounding the Installation
The Outdoor Unit (ODU) must be properly grounded to protect against power surges. It is the
user’s responsibility to install the equipment in accordance with Section 810 of the National Electric
Code, ANSI/NFPA No.70-1984 or Section 54 of the National Electrical Code in the country of
installation. 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. It is recommended that installation of the outdoor unit be contracted to
a professional installer.
Installation
53
7.7.7 Making the ODU Connection at the PTP 500 Series Bridge PIDU Plus
The ODU is connected to the PIDU Plus by means of a concealed RJ45 connector. The RJ45 con-
nection has been placed inside the PIDU Plus hinged cover to prevent the user from inadvertently
plugging other equipment into the ODU RJ45 socket.
CAUTION: Plugging other equipment into the ODU RJ45 socket may damage the equipment
due to the non-standard techniques employed to inject DC power into the 1000BaseT connection
between the PIDU Plus and the ODU. Plugging the ODU into other equipment may damage the
ODU and/or the other equipment.
Step 1: Undo the retaining
screw and hinge back the cover
Step 2: Plug in the ODU into the PIDU
Plus Cable ensuring that it snaps home
Step 3: Replace the cover and secure with the retaining screw
Installation
54
7.7.8 Making the Network Connection at The PIDU Plus – PTP 500 Series Bridge
The Network connection is made by connecting the user’s Network Equipment directly to the
PIDU Plus LAN port as shown in Figure 23.
Figure 23 Making the Network Con-
nection at the PIDU Plus
7.7.9 Mounting the PTP 500 Series Bridge PIDU Plus
This step is optional. Motorola recommends that you mount the PIDU Plus on a wall or other
suitable mounting surface. This prevents the unit from being knocked or kicked and can help
maintain link availability. Ensure that the Recovery switch can be accessed when mounting the
unit.

Make connections as per Section 7.7.8
Installation
55
CAUTION: The PIDU Plus is not waterproof and should be mounted away from sources of
moisture. If mounted outdoors, the unit should be mounted in a rain proof enclosure, preferably
ventilated.
It is also recommended that you fit a drip loop on the PIDU Plus to ODU cable to ensure that
any moisture that runs down the cable into the cabinet or enclosure cannot enter the PIDU Plus.
As shown in Figure 24. The network connection and mains cable should be treated in the same
way if there is a risk that they can carry moisture to the PIDU Plus.
Figure 24 PTP 500 Series PIDU Plus Drip Loop Configuration
CAUTION: It is possible for moisture to enter the cable due to damage to the outer protective
layer. This moisture can track down the inside of the cable, filling up the drip loop and eventually
finding its way into the PIDU Plus. To protect against this the outer protective layer of the cable
can be opened up at the bottom of the drip loop to allow this moisture to escape.
7.7.10 Powering Up
The PTP 500 Series Bridge is supplied as a pair of matched Master/Slave units. The Master unit
can now be powered up and accessed using the default URL http://169.254.1.2/; the Slave unit
can be accessed using http://169.254.1.1/.
Prior to powering up the PTP 500 Series Bridge, a computer with web browsing capabilities should
be configured with an IP address of 169.254.n.n and subnet mask of 255.255.0.0 where n is any
value between 1 and 254 but excluding 1.1 or 1.2. If the default addresses of the unit 169.254.1.1/2
clashes with an address you are already using on your LAN, or you are not sure, you should set up
an isolated LAN. As the LAN connection presented at the PIDU Plus has a default configuration
Installation
56
as a hub/switch (and auto-sensing MDI/MDIX cross over is employed), connection can be made
directly to the computer using a standard CAT 5 patch cable.
Before physical installation takes place the units to be installed should be set up as described in
the Section 8.3.4 "Install Pages". It is recommended that this procedure be carried out on the
bench before physical installation commences. Providing it is safe to do so, the installer should
take the process to the point where a radio link is established before proceeding to the installation
site.
NOTE: It is possible that some units may not be accessed using the above default URL. This is
because these units may have been previously configured with IP addresses 10.10.10.11 (Master)
and 10.10.10.10 (Slave). Therefore, users must use the URL http://10.10.10.10/ and/or URL
http://10.10.10.11/ to configure the units. Please ensure that a computer with web browsing
capabilities is configured with an IP address of 10.10.10.n, where n is any value between 2 and 254
but excluding 10 and 11, to configure these units.
7.7.11 Aligning the PTP 500 Series Bridge ODUs
The following is a description of the steps taken to establish a radio link between the two units
forming the bridge and align the units for the best signal strength.
The PTP 500 Series Bridge uses audible tones during installation to assist the installer with
alignment. The installer should adjust the alignment of the ODU in both azimuth and elevation
until highest pitch tone is achieved6. The tones and their meanings are as follows:
State Name Tone Description State Description Pitch Indication
(Higher pitch =
higher power)
Free Channel Search Regular beep Executing band scan N/A
Scanning Slow broken tone Not demodulating the
wanted signal
Rx Power
Synchronized Fast broken tone Demodulating the
wanted signal
Rx Power
Registered Solid tone Both Master and Slave
units exchanging Radio
layer MAC management
messages
Rx Power
Table 11 Audio indications from the ODU
The term ‘wanted signal’ refers to that of the peer unit being installed.
In each of the states detailed above, the unit should be aligned to give the highest pitch tone. It
should be noted that if, when in the Synchronized or Registered state, the tone varies wildly, you
The pitch of the alignment tone is proportional to the received power of the wireless signals. The best results are
6
usually achieved by making small incremental movement in angular alignment.
Installation
57
may be suffering from interference or a fast fading link. Installing in this situation may not give a
reliable link. The cause of the problem should be investigated.
For the ease of alignment, both Master and Slave units use the install tones in the same way but
with some small behavioral differences. This allows the installer to install the Slave unit first and
carry out the initial alignment with the Master unit if desired. However, due to the behavioral
differences of Master and Slave units, it is recommended that the Master unit is installed first and
the initial alignment carried out at the Slave unit.
Note also that there is a graphical installation screen (Section 8.3.5 "Graphical Install") avail-
able using the web interface that displays the state of the link during the alignment process (up
green,Down, red).
The following behavior should be noted:
•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.
•The master unit can take up to 60 seconds in 0-40km (0-25 miles) mode, 90 seconds in 0-130km
(0-81 miles) mode and 120 seconds in 0-200km (0-124 miles) mode to determine the range of
the link being installed7. 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.
•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.
•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.
When the alignment process is complete the installer MUST REMEMBER TO DISARM8BOTH
UNITS in the link as described in Section 8.3.4 "Install Pages". This is necessary in order to:
•Turn off the audible alignment aid (Section 8.3.4.4 "Disarm")
•Enable Adaptive Modulation
•Fully enable Advanced Spectrum Management with i-DFS
•Clear unwanted installation information from the various systems statistics
•Store the link range for fast link acquisition on link drop
•Enable higher data rates
If the unit is operating where mandatory radar avoidance algorithms are implemented the ranging behavior for the
7
PTP 500 Series Bridge 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.
After 24 hours, the units will be disarmed automatically provided that they are armed and that the link is UP.

8.1 Home Page – PTP 500 Series Bridge
The home page for the PTP 500 Series Bridge has been designed to display a high level summary
of the status of the wireless link and associated equipment. The home page (Figure 26) normally
displays four key system attributes:
Wireless Link Status: The Wireless Link Status attribute displays the current status of the
PTP 500 Series Bridge 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.
Link Name: The link name attribute is a name and/or handle allocated by the system adminis-
trator to aid the identification of the unit, network or building.
Figure 26 System Summary Page
Elapsed Time Indicator: The elapsed time indicator attribute presents the total time in days,
hours, minutes and seconds since the last system restart. The system can restart for several reasons,
e.g., commanded reboot from the system reboot webpage, or a power cycle of the equipment.
System Clock: If SNTP (Simple Network Time Protocol) is enabled, or the clock has been
set, then a system clock attribute is displayed giving the date and time of the last page refresh.
Section 8.3.10.8 “SNTP (Simple Network Time Protocol) explains how to enable SNTP and
Section 8.3.10.9 explains how to set the clock.
8.1.1 Home Page Alarm Display
The home page is also used to display all outstanding major system alarms. Whenever system
alarms are asserted, a yellow warning triangle is displayed on web page navigation bar. The warning
triangle will be visible from all web pages. Clicking the warning triangle will cause the web page
to jump back to the system homepage. Figure 27 shows a sample alarm screen.
Web Page Reference
60
Figure 27 Alarm Warning Triangle
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 misconfigured 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 instal-
lation 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 ‘Installa-
tion Wizard’ see Section 8.3.4.4 “Disarm”. Note that 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. Note that a change of state may generate an SNMP
trap and/or SMTP email alert.
Incompatible Region Codes: The PTP 500 Series Bridge uses region codes to comply with
local regulatory requirements governing the transmission of wireless signals in the 5.8, 5.4 GHz
and 2.5 GHz bands. Region codes can only be changed by obtaining a new PTP 500. Note that a
change of state may generate an SNMP trap and/or SMTP email alert.
Web Page Reference
61
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 Alarm: 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 8.3.10.8 “SNTP
(Simple Network Time Protocol) explains how to configure SNTP. Note that a change of state
may generate an SNMP trap and/or SMTP email alert.
Wireless Link Disable Warning: This warning is displayed if the Wireless link has been admin-
istratively disabled via the SNMP Interface (see Section 8.3.10 “Remote Management Page”).
The Wireless Interface MIB-II ifAdminStatus attribute has been set to DOWN. To enable the Eth-
ernet 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 Disable Warning: This warning is displayed if the Ethernet link has been admin-
istratively disabled via the SNMP Interface (see Section 8.3.10 “Remote Management Page”).
The Ethernet Interface MIB-II ifAdminStatus attribute has been set to DOWN. To enable the Eth-
ernet 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.
TDD Synchronization Status: Current status of the TDD Synchronization (acquiring synchro-
nization, no timing reference and timing system not connected). Note that a change of state may
generate an SNMP trap and/or SMTP email alert.
8.2 Systems Status Page
The status page has been designed to give the system administrator a detailed view of the operation
of the 500 Series Bridge from both the wireless and network perspectives.
Web Page Reference
62
The page is subdivided into three main categories Equipment, Wireless and Ethernet/Internet. The
‘Equipment’ section contains the unit’s inventory and identification information. The ‘Wireless’
section presents the key wireless metrics, which are displayed as a series of measurements. The
‘Ethernet/Internet’ section describes the unit’s network identity and connectivity.
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 500 Series Bridge at this interval.
The two PTP 500 Series bridges 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.
Figure 28 Status Page
The following section details all the attributes 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.
Link Location: The link location 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 link location 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, 5.4 or 5.8
GHz), SSS is the System Release, XX is the major release version and YY is the minor release
version.
Web Page Reference

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 / 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 sev-
eral reasons, e.g. commanded reboot from the system reboot web page, or a power cycle of the
equipment.
Ethernet Link Status: Current status of the Ethernet link. A state of ‘Up’ with a green back-
ground 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.
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 Adminis-
trator.
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 per-
mitted 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 histogram10 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.
An histogram is calculated over a one hour period. If the equipment has been running for less than one hour then
10
the histogram is calculated over the current elapsed time. The data used to compute the histogram statistics can
be downloaded in an ASCII comma separated value (CSV) format via the diagnostics CSV Download page, see
Section 8.3.11.2 “Diagnostics Download”.
Web Page Reference

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 footnote 10 “histograms”.
Vector Error: The vector error measurement compares the received signal’s In phase / Quad-
rature (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 approx-
imately -2dB (NLOS link operating at sensitivity limit on BPSK 0.67) to -33dB (short LOS link
running 256 QAM 0.83). See footnote 10 “histograms”.
Link Loss: The link loss is the total attenuation of the wireless signal between the two point-to-
point units. See footnote 10 “histograms”.
The link loss calculation presented below:
Pl=PT−PR+gT+gR(4)
Where
Pl= Link Loss dB
PT= Transmit power of the remote wireless unit dBm
PR= Received signal power at the local unit dBm
gt,g
r= Antenna gain at the remote and local units respectively11 dBi
Equation - Link Loss
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.
See footnote 10 “histograms”. Expected data rates can be found in Section 14 “Data Rate
Calculations”.
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.
See footnote 10 “histograms”. Expected data rates can be found in Section 14 “Data Rate
Calculations”.
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. List of all the modulation modes can be found in Section 14 where data rate calculations
plots are given for each available modulation mode.
The antenna gain of the 500 Series bridge (23.5 dBi) is used unless one or both of the units is a Connectorized
11
version.

Receive Modulation Mode: The modulation mode currently being used on the receive channel.
List of all the modulation modes can be found in Section 14 where data rate calculations plots
are given for each available modulation mode.
Receive Modulation Mode Detail: This supplies the user with information regarding the
receive modulation mode in use. Possible values are:
•Running at maximum receive mode
•Running at user-configured Max Modulation Mode
•Restricted due to byte errors on the wireless link or local Ethernet Tx Fifo Drops
•Restricted because a DFS channel change is in progress
•Restricted due to telecoms acquisition mode
•Restricted due to the low Ethernet link speed
•Limited by the wireless conditions
Range: The range12 between the 500 Series bridge ODUs.
8.3 System Administration Pages

8.3.1 System Configuration
The configuration of the 500 Series Bridge is organized into three sections:
•General configuration
•LAN configuration
•Telecoms Configuration
•Save and Restore
The general configuration allows modification of high level administrative (descriptive) attributes
and high level wireless configuration.
The LAN configuration sub menu allows the system administrator to modify the Ethernet and IP
configuration of the 500 Series Bridge.
The telecoms submenu displays the current status of the telecoms interface and allows the config-
uration of interface loopbacks.
The save and restore submenu allows the system administrator to backup and restore the bridge
configuration. It is recommended after a unit has been successfully installed; a copy of the active
configuration is taken and archived by the system administrator.
8.3.1.1 General Configuration Page
The general configuration page (Figure 30) is used by the system administrator to configure
the 500 Series Bridge’s high level administrative (descriptive) attributes and high level wireless
configuration.
Web Page Reference
67
Figure 30 System Configuration Page
While the majority of the system configuration is entered during installation and should never
require changing, this page offers the system administrator the ability to change the basic system
parameters for both the wireless and Ethernet components.
Link Name: User defined identity for the unit (max 63 characters).
Link Location: Can be used as a generic scratch pad to describe the location of the equipment.
Master Slave Mode and Link Mode Optimization current settings are displayed and can be
modified using the Installation Wizard pages. See Section 8.3.4 “Install Pages”
Max Receive Modulation Mode: This is the maximum mode the unit will use as its adaptive
modulation. By default the Max Receive Modulation Mode is the highest mode available.
For minimum error rates on TDM links the user should set the maximum modulation mode to
64QAM 0.75 at both ends of the link.
Ethernet Capped Max Wireless Speed: When enabled this option will cap the wireless speed
to a mode that the connected Ethernet connection can sustain.
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 regulations13.
In the UK there is a legal requirement to provide a minimum of 19dB of transmit power control range. When the
13
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 19dB compared to the maximum allowed with a simple single step
control.
Web Page Reference
68
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,
e.g. fixed satellite links.
8.3.1.2 LAN Configuration Page
The LAN configuration page (Figure 31) is used by the system administrator to configure the
500 Series Bridge’s LAN interface.
Figure 31 LAN Configuration Page
IP Address: Internet protocol (IP) address. This address is used by the family of Internet
protocols to uniquely identify this unit on a network.
Subnet Mask: A subnet allows the flow of network traffic between hosts to be segregated based
on a network configuration.
Gateway IP Address: The IP address of a computer / router on the current network that acts
as a gateway.
Web Page Reference
69
VLAN High Priority Traffic Threshold: All packets with an 802.1P priority tag greater than
or equal to the indicated value will be treated as a high priority packet for transmission over the
wireless link.
Use VLAN For Management Interfaces: This controls whether the management interfaces
(WWW/SNMP/SMTP/SNTP) use 802.1Q VLAN tags or not. See Section 8.3.1.3 “LAN Con-
figuration Page - Use VLAN For Management Interface”.
Ethernet Auto Negotiation: This enables the Ethernet configuration to be forced rather than
auto negotiated.
Caution:The configuration should only be forced if you are having problems with auto
negotiation. You must ensure that you configure both this unit and the Ethernet port
to which it is connected identically. If you force a fixed Ethernet Configuration on
the 500 Series bridge then you MUST also force the same fixed configuration on
the equipment to which it is connected. If you fail to force the configuration of the
connected equipment, its automatic configuration mechanisms will normally cause a
duplex mismatch, and you will receive greatly reduced throughput!
When Ethernet Auto Negotiation is Disabled the format of the LAN configuration page will change
see Section 8.3.1.4 “LAN Configuration Page – Manual Ethernet Configuration”.
Auto Neg Advertisement: This controls the rates that the auto negotiation mechanism will ad-
vertise as available. Warning: Over the air throughput will be capped to the rate of the Ethernet
interface at the receiving end of the link.
Ethernet Auto Mdix: This enables/disables the Auto Medium Dependent Interface (MDI)/Medium
Dependent Interface Crossover (MDIX) capability. Default is “Enabled”.
Drop Ethernet Link On Wireless Link Down: When this option is enabled the Ethernet
link is momentarily dropped when the wireless link goes down. This feature is used to indicate to
the connected network equipment that this Ethernet link is no longer available, thus causing STP
(Spanning Tree Protocol) to re-route packets through an alternate link.
Local Packet Filtering: When Local Packet Filtering is “Enabled”, the bridge learns the source
MAC addresses of devices transmitting Ethernet packets on the local Ethernet network, and only
bridges packets to the remote unit if the destination MAC address has not been learned as a
’local’ device. When Local Packet Filtering is ‘Disabled’ the bridge does not learn the source MAC
addresses of devices transmitting Ethernet packets on the local Ethernet network, and bridges
ALL Ethernet packets received to the remote unit. Local Packet Filtering should be disabled when
external Ethernet switching hardware or a router is present. The default setting for Local Packet
Filtering is disabled.
All of the above attributes are non-volatile, once set they will be used by the unit even after a power
on reboot. A number of attributes, such as IP Address, Subnet Mask and Gateway IP Address and
VLAN settings will require a reboot before they are used. If any of these attributes are changed a
reboot screen appears asking the user to verify the reboot (Figure 32 or Figure 33).

This will be followed by a pop-up dialogue box asking to confirm the action.
Note: At this point you will lose connection to the unit. If you have just changed the IP Address
you now have to reconnect to the unit using the address just set.
8.3.1.3 LAN Configuration Page – Use VLAN For Management Interfaces
The layout of the LAN Configuration page changes if this attribute is enabled in order to allow the
VLAN VID and VLAN Priority to be set, see Figure 34. The VLAN settings are applied only
after the unit is rebooted.
Web Page Reference
71
Caution: You must ensure that you can access the VLAN which you configure here, otherwise
you will be unable to access the unit following the next reboot.
Caution: The PTP 500 is only compatible with single VLAN tagged packets. Any packet with
two or more tags will be ignored.
Figure 34 VLAN Configuration Fields
VLAN Management VID: This 802.1Q VLAN VID will be included in packets generated by
the management interfaces. Valid settings are in the range 0 to 4094.
VLAN Management Priority: This 802.1Q VLAN Priority will be included in packets generated
by the management interfaces. Valid settings are in the range 0 to 7.
VLAN Management VID Validation: If enabled, the management interfaces will only respond
to Ethernet packets tagged with the configured 802.1Q VLAN Management VID; otherwise packets
with any VID will be accepted.

8.3.1.5 Save and Restore Configuration File
The save and restore feature of a PTP 500 Series Bridge allows the system administrator to
backup the operation configuration of the wireless unit. It is recommended that this facility is
used immediately after a successful PTP 500 Series Bridge installation or prior to any software
upgrade. In the unlikely event that a unit has to be replaced in the field, the replacement unit can
be reconfigured by simply playing back the saved configuration file.
To save the configuration file click on the ‘Save Configuration File’ button (Figure 36) and save
the configuration file (.cfg) to the hard drive of your computer14 15.
Figure 36 Save and Restore Configuration Page
There is a feature of Internet Explorer (all versions) that will always look at the content of any downloadable file
14
as make an assessment whether to treat the file as an ASCII or binary file. Unfortunately the configuration file is
always treated as ASCII and the browser attempts to display it instead of downloading it. Firefox (all versions)
makes no such assumptions.
The configuration file format is MAC-mm-mm-mm_IP-iii-iii-iii-iii.cfg where mm and iii are the lower 3 bytes of the
15
MAC address and the unit IP address respectively.
Web Page Reference

75
The configuration file is encoded using an ASCII encoding scheme. An example is show in
Figure 38.
Figure 38 PTP 500 Example Configuration File
CAUTION: The configuration file is currently restricted to a single software version and can
only be restored into a wireless unit operating the software version indicated in the configuration
file header.
The configuration file can also be used when swapping out a faulty wireless unit. If one of the
wireless units is replaced on a wireless link a configuration file captured from the faulty unit can
be uploaded into the new unit to speed up replacement. It should be noted that when placing
a configuration file into a wireless unit with a different MAC Address the license key will not be
restored and may need to be entered. This can be obtained either from the Quick Start Guide
supplied with the replacement wireless unit or directly from Motorola. Note that the target MAC
address at the other end needs to be changed to ensure that it is using the MAC address of the
replaced unit.
The restoration of configuration files can be performed using the Restore configuration tool. Using
the browser button to locate the configuration file you wish to restore then click the ‘Restore
Configuration File and Reboot’ button (Figure 39). The user will then be prompted to confirm
the action (Figure 40)
Web Page Reference
76

On confirmation the PTP 500 Series Bridge will:
•Upload the configuration file
•Perform data integrity checking
•Erase previous configuration
•Apply the new configuration
•Restart
After the unit has restarted the entire configuration from the configuration file will now be active.
Note: The IP address of the unit may have also been changed. The user can check the new IP
address by reading the header of the configuration file, Figure 38.
CAUTION: A reboot is always required to restore a configuration file.

8.3.4 Install Pages
These pages are used during system installation. There follows a description of the install pages
along with their use during the installation configuration process. The actual installation process
is described in Section 8.3.4.1 “Manually Configuring the Wireless Units”.
All wireless links are shipped as paired units. They are pre-configured at the factory so that
they can be installed without the user supplying any configuration. Each wireless link is shipped
with a quick start guide. Attached to the quick start guide is a summary of the pre-configured
configuration data. Table 12 shows a sample link configuration. The values highlighted have been
committed to the wireless unit’s non-volatile storage.

Factory Configuration Values
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 <5Km(<3
miles) you must follow the steps in Section 8.3.4.1 “Manually Configuring The Wireless Units”.
The factory default configuration is set to Region 26. Region 26 allows the 500 Series bridge 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 Section 8.3.4.1
“Manually Configuring The Wireless Units”.
8.3.4.1 Manually Configuring The Wireless Units
If the installer / system administrator wishes, they may modify the default installation configu-
ration. If only the IP addresses (network configuration) are incorrect it is recommended that the
values are changed via the configuration menu (Section 8.3.1.2 “LAN Configuration Page”). If
Web Page Reference
84
any other parameters require modification then it is recommended that the system administrator
use the Installation Wizard.
A detailed description of the Installation Wizard follows: The 500 Series bridge operational software
requires a license key to enable the wireless bridging capability and programs region code specific
parameters in to the unit.
Figure 43 License Key Data Entry
A license key is programmed into each unit during production and can be found written on the
Configuration Data Summary Label which is attached to the Quick Install Guide. If subsequently
the license key has been mislaid, replacement keys can be applied for online or via your distributor.
If a valid license key is not detected in the unit’s non-volatile memory then the user is prompted
to enter a valid key. It should be noted that 500 Series bridge units are shipped as link pairs and,
as such, valid license keys are entered during the production process. To enter a license key simply
type or paste the license key into the data entry box (Figure 43) and click the ‘validate license
key’ button.
8.3.4.2 Internet Protocol Configuration
Step 1 of the installation wizard requires the installer to enter the Internet Protocol (IP) configu-
ration.

Subnet Mask:A subnet allows the flow of network traffic between hosts to be segregated based on
a network configuration. By organizing hosts into logical groups, subnetting can improve network
security and performance. Gateway IP Address: The IP address of a computer / router on the
current network that acts as a gateway. A gateway acts as an entrance / exit to packets from / to
other networks.
Use VLAN Management Interface:Controls whether the management interfaces (HTTP/SNMP
/SMTP/SNTP) use a VLAN. Selecting this option presents the user with extra fields in which to
enter the Management VLAN ID, Priority and whether to validate the VLAN ID. If the user
modifies this control, a warning dialog is displayed see Figure 45.

Target MAC Address:It 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
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).
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.
In IP Mode, the PTP 500 product runs an Adaptive TDD scheme. Basically an unloaded link
runs 10:10 mode (10 OFDM bursts alternately in each direction). A sustained traffic load in one
direction for example may cause a threshold to be reached where the TDD mode automatically
adapts to say 20:10. If the load continues to increase, then the TDD structure may adapt even
further through 30:10 to 40:10. This is a state of maximum link asymmetry (40 OFDM bursts
in one direction compared with 10 in the other). If the load increases in BOTH directions, then
the TDD structure can adapt from 10:10, through 20:20, 30:30 and finally 40:40. This is a state
of maximum aggregate throughput. So if three out of these combinations are considered; 10:10,
40:10 and 40:40 they would give the following characteristics:
10:10: equal performance in each direction, lowest aggregate throughput and lowest Latency.
40:10: achieves maximum one way throughput performance, to the detriment of both latency and
throughput in the opposite direction.
40:40: Maximum link aggregate rate, balanced performance in each direction, higher latency.
Note that there is an engineering trade-off between the flexibility of ATDD and Latency as follows:
When the TDD structure changes, there will be a short term impact on Latency for a few Frames.
This would not affect the steady state long term average latency, but could be recorded as a
Maximum latency. This affect may be amplified for short Latency tests or if the traffic loading
is oscillating either side of a boundary condition. As the TDD burst length increases, Traffic in
each direction will have to wait longer before a Transmit window is available, but more data can
be sent during the burst. There is an impact on latency but it varies depending upon installation
range, Frame size and modulation mode.
In TDM mode, two major differences in link behaviour occur compared with IP mode. First the
TDD structure is fixed symmetrically. Either 10:10, 20:20, 30:30 or 40:40 based upon the installed
range.
Secondly, the point at which a modulation mode changes for given RF conditions is more conser-
vative. In practice, this means that the link will typically stay in a lower modulation mode, but
with increased tolerance to RF variability.

Depending upon the link characteristic that the customer requires, this may very well be the best
choice. It increases consistency of link performance and equality in each direction as a trade-off
against maximum throughput.
Tx Max Power:This attribute controls the maximum transmit power the unit is permitted to
use when installing and executing the wireless link. The maximum setting for a particular region
or country is controlled by the License Key.
Platform Variant:Chooses between an integrated unit or a connectorized unit that requires an
external antenna.
Channel Bandwidth:Users can choose a variable channel bandwidth for the available spectrum.
Value is 15 MHz.
Spectrum Management Control:Is used to configure the PTP 500 Series Bridge’s Spectrum
Management features, see Section 8.3.7 “Spectrum Management” for more details. i-DFS is the
abbreviation for intelligent Dynamic Frequency Selection. This feature continually monitors the
spectrum looking for the channel with the lowest level of on channel and co-channel interference.
Fixed frequency mode allows the installer to fix transmit and receive frequencies on the units. The
frequencies may be configured symmetrically or asymmetrically.
Lower Center Frequency:The software for the PTP 500 Series Bridge 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. See
Sections Section 5.5 “5.4 GHz Specific Frequency Planning Considerations” and Section 5.6
“5.8 GHz Specific Frequency Planning Considerations” depending on the frequency variant.
Warning: 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.
Fixed Transmit Frequency, Fixed Receive Frequency:The software for the PTP 500 Se-
ries Bridge 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 or
adjacent channel interference. Therefore this mode of operation is only recommended for deploy-
ments where the installer has a good understanding of the prevailing interference environment.
Figure 47 shows a sample fixed frequency configuration for a 30 MHz channel bandwidth. In the
example the lower center frequency is set to its default values and 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 5 MHz channel raster as the Lower Center Frequency. For example 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). Please note that there is a raster that
limits the selection of the Rx frequency based upon the setting of the Tx frequency, and that the
list of options presented in the fixed Tx frequency box is limited to that raster.

After installation the system administrator may wish to modify the wireless units descriptive con-
figuration (link name and link location). In addition the system administrator may wish to change
the spectrum management configuration of the wireless unit, or look at the analysis of the 5.8 GHz
spectrum to see if the automatic channel selection is appropriate for the system administrator’s
network. It is also recommended that a backup copy of the wireless units configuration is taken.

8.3.5 Graphical Install
To aid the installation of wireless links two graphical installation aids have been introduced in this
500 Series system version.
•A PDA installation screen
•A larger installation screen available from the main HTTP management interface.
The design of the installation screen has been deliberately kept simple and uncluttered. An example
of the installation screen is shown in Figure 53. Both the PDA and the large format installation
screen have the same content and only differ in size. The PDA installation screen is 232 by 220
pixels to be compatible with the typical size of a PDA screen.
Figure 53 Graphical Installation Screen
The screen displays the receive power over the last three minutes. This will allow the installer
to slowly sweep the antenna during installation and monitor the variation in signal strength with
angular position. The screen automatically refreshes every three seconds.
The screen also displays the current state of the wireless link in two ways. First, the actual state
of the wireless link is written in the top left corner of the screen. The instantaneous receive power
bar also encodes the state of the wireless link using green to signify that the wireless link is up and
red for all other states.
For the more technically aware, the installation metric is simply the instantaneous receive power
in dBm + 100.
The PDA installation tool is accessed via a hidden URL http://<ip-address>/pda.cgi. It should
be noted that this link is only available after the user has logged in as system administrator.
The large screen version of the graphical user interface is available as a submenu option of the
installation wizard.

8.3.6 Software Upgrade
The 500 Series system has two software image banks; one is a fixed image which is stored in
protected non-volatile memory and cannot be modified by the user. The second bank is used by
the system administrator to upgrade the firmware when necessary. Figure 54 shows the main
software upgrade web page.
Figure 54 Software Upgrade
The ‘Fixed’ or ‘Recovery’ image is used by the System Administrator to:
•Reset Ethernet configuration to default settings
•Erase Configuration
•Upgrade software
For a full description of the Recovery image see Section 9 “Recovery Mode”.
The software upgrade pages are used to update a unit’s operational software. The software image
to be uploaded should be downloaded to local storage from the Motorola web site. The software
image is delivered by Motorola as a compressed zip file. Once the zip file has been downloaded,
the user should extract the PTP 500 Series Software image, identifiable by its ‘.dld’ file extension.
The first step (Figure 54) is to use the “Browse” button to locate the software image previously
downloaded to local storage from the Motorola web site. Once the image is located, the user should
press the “Upload image to wireless unit” button to start the software upgrade process18.
During the software upgrade process, ensure that the remote end is upgraded first using the wireless connection and
18
then the local end can be upgraded.
Web Page Reference
96
The software image will now be uploaded to the unit. This upload should only take a few seconds.
Once complete the image is verified and validated to ensure that no errors occurred during transfer
and that the image is valid to run on the current platform. If there are any problems a warning
screen will appear.
The unit being upgraded will now display information about the build it currently has stored in
the image bank and the one that’s just been uploaded. If the image is not the right one, the user
has the option to go back and reload a new image. (See Figure 55)
Figure 55 Software Upgrade Image Check
The user should ensure that the correct image is shown before pressing the “Program Software
Image into Non-Volatile Memory” button. Once this button has been pressed the image is stored
into non-volatile memory, this process can take up to 60 seconds and must not be interrupted.
If the upgrade process is interrupted during the erasure of the image bank, or during the repro-
gramming of the image bank, the image bank will be left in a corrupt state. If this occurs the
software must be reloaded. All software images that are stored in non-volatile memory are pro-
tected via the use of CRCs. If the software detects an invalid CRC the image bank is marked as
‘corrupt’ and the 500 Series bridge boot code will boot the fixed software image. If this occurs the
user must attempt to reload the correct version of software.
During the write process the progress of the upgrade is displayed on the progress tracking page
(Figure 56). The upgrade process should not be interrupted. Interruption of this process can
result in a corrupt main software image, which will result in the recovery image been booted at
the next reset cycle.
Web Page Reference

Figure 56 Software Download Progress Indicator
Figure 57 Software Upgrade Complete
When the software image has been written to non-volatile memory Figure 57 will be displayed
showing the status of the software upload.
Reboot the unit by clicking the “Reboot Wireless Unit” button. You will be asked to confirm this
action as shown in Figure 58.
Figure 58 Reboot Confirmation Pop Up
This will reboot the unit, taking up to 120 seconds. During this time you will not be able to
communicate with the unit.
Web Page Reference
98
If you cannot communicate with the unit after 120 seconds, this could indicate a problem with the
memory update process. Under these circumstances the user should enter “Recovery Mode”, see
Section 9 “Recovery Mode”.
After the reboot the user should check that the required software image is loaded and running.
NOTE: Please ensure that you are upgrading the correct units. Units cannot be downgraded..
8.3.7 Spectrum Management
Spectrum Management Selection is the PTP 500 Series Bridge 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.
8.3.7.1 Wireless Channels
The PTP 500 Series Bridge operates using a set of predefined overlapping channels. There are a
different number of channels, depending on the raster mode selected. Each channel occupies 15
MHz of wireless spectrum and is offset in center frequency from its neighboring channel by 5 MHz.
It is important to note that adjacent channels on the Spectrum management display have a 5 MHz
overlap to the adjacent channel.
The default channelization can be modified by varying the lower center frequency attribute in
the installation wizard - see Section 8.3.4.3 “Wireless Configuration”. See Section 5 “General
Considerations” for more detail.
8.3.7.2 Spectrum Management Measurements
The 500 Series Bridge 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.
8.3.7.3 Measurement Analysis
Spectrum Management uses statistical analysis to process the received peak and mean measure-
ment. 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:
Web Page Reference
99
•Peak of Means
•99.9% Percentile of the Means
•Mean of Means
Peak of Means: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 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:is the arithmetic mean19 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.
Important Note: Spectrum Management uses the 99.9% percentile as the prime interference
measurement. All subsequent references to interference level refer to this percentile measurement.
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.
8.3.7.4 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.
The arithmetic mean is the true power mean and not the mean of the values expressed in dBm.

Figure 60 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.
8.3.7.5 Spectrum Management Configuration
The following section describes the user modifiable configuration accessible from the Spectrum
Management webpage. 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 your Motorola Point-to-Point distributor or one of the
system field support engineers.
Page Refresh Period: The page refreshes automatically according to the setting entered here
(in seconds).
Web Page Reference
102
Hopping Margin:Spectrum Management uses this margin when making a channel hop decision.
The target channel has to have an interference level 3 dB (default) better than the current active
channel.
Hopping Period (not configurable):The Spectrum Management algorithm evaluates the met-
rics 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 chan-
nel 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: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 in-
stantaneous channel hops. If the measured interference on a channel exceeds the specified threshold,
then iDFS will instruct the wireless to immediately move to a better channel. If a better channel
cannot be found the 500 Series Bridge will continue to use the current active channel. (Default -85
dBm)
Asymmetric DFS:The default configuration of symmetric operation constrains the link to op-
erate 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.
Channel Bandwidth (not configurable):shows the value of the variable channel bandwidth
selected.
8.3.7.6 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.
8.3.7.7 Master and Slave Channel Spectrum Graphics
Spectrum Management presents its computed statistical measurements in a graphical display on
both the master and slave Spectrum Management web page.
Web Page Reference
103
Figure 61 Example Spectrum Management Graphic
The X-axis shows a stylized view of the selectable wireless channels. It is important to note that
adjacent channels on the display have a 10 MHz overlap. The display separates the display of
channels to help the clarity of the resultant display. The axis is labeled using the channel center
frequencies in MHz.
The Y-axis shows the interference power levels from -100 to -40 dBm.
The active channel (channel 5 in Figure 61) is always marked using hatched green and white lines.
The width of the hatching is directly proportional the channel bandwidth spectral occupancy of
the channel.
The individual channel metrics are displayed using a colored bar and an ‘I’ bar.
The colored bar represents the following channel state:
Web Page Reference
104
Green Active The channel is currently in use, hosting the Point-to-Point wireless
link.
Orange Interference The channel has interference above the intererence threshold
Blue Available The channel has an interference level below the interference threshold
and is considered by the Spectrum Management algorithm suitable for
hosting the Point-to-Point link.
Grey Barred The system administrator has barred this channel from use. For
improved visibility, an additional red ’lock’ symbol is used to indicate
that a channel is barred
Table 13 Spectrum Management change state key
The top of the colored bar represents the 99.9% percentile metric for specific channel. The ‘I’
Bar is used to display the mean of means and peak of means metrics. The lower horizontal bar
represents the mean of means and the upper horizontal bar represents the peak of means. The
vertical bar is used as a visual cue to highlight the statistical spread between the peak and the
mean of the statistical distribution.
8.3.7.8 Active Channel History
The active channel history is a time series display of the channels used by the PTP 500 Series
Bridge over the last 25 hours. The active channel history is activated from the main Spectrum
Management page using the ‘Active Channel History’ hyperlink. An example of the active channel
history display is shown in Figure 62. Where there are parallel entries on the display this signifies
that the wireless link occupied this channel during the measurement period. The measurement
periods are one minute (from zero to sixty minutes) and twenty minutes from (60 minutes to twenty
five hours).

8.3.7.9 Viewing Historic Spectrum Management Metrics
Spectrum Management allows the system administrator to view the results of previous measure-
ment quantization periods. Holding down the shift key and clicking the appropriate channel on the
local channel spectrum plots activates this feature. This feature is available on both the master
and slave web page.
Figure 63 Spectrum Management Time Series Plot
Figure 63 shows an example time series plot. A time series plot displays the previous 132 measure-
ment quantization periods. If the PTP 500 Series Bridge has not been running for 132 quantization
periods then only the number of measurement quantization periods that are available are displayed.

BLACK 99.9% percentile of means intinterference measurement
BLUE Mean of means interference measurement
Table 14 Spectrum Management Time Series Key
8.3.8 Spectrum Management (Fixed Frequency)
The PTP 500 Series Bridge 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 Section 8.3.4.3 “Wireless Configuration”). 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 64.
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’.
Web Page Reference
106
Figure 64 Spectrum Management Fixed Frequency Screen
Channel barring is disabled in fixed frequency mode; it is not required as dynamic channel hopping
is prohibited in this mode.
The only controls available to the master are the Statistics Window and Interference Threshold
attributes. They will have no effect on the operation of the wireless link and will only effect the
generation of the channel spectrum graphics.
The active channel history menu is removed in this mode of operation as channel hopping is
prohibited.

8.3.9 Spectrum Management Control – With Operational Restrictions
When operating with Radar Avoidance enabled the following variances in operation apply:
•The words “Radar Avoidance” are appended to the “Spectrum Management” title at the top
of the screen. See Figure 66 and Figure 67.
•The only controls available to the master are the Interference Threshold attribute. This has
no effect on the operation of the wireless link and will only affect the generation of the channel
spectrum graphics. See Figure 66.
•Extra color coding of the interference histogram is provided. See Table 15.
When operating with RTTT (Road transport and Traffic Telematics) Avoidance enabled or
other regulatory restrictions on channel usage the following variances apply:
•All channels marked with a ‘no entry’ symbol with their associated statistics colored black are
the prohibited channels. See Figure 66 and Figure 67. These channels are never used to
host the wireless link, but CAC measurements are still taken so that adjacent channel biases
can be calculated correctly and so the user can see if other equipment is in use.

remote management of the PTP 500 Series Bridge.
8.3.10.1 Control Access to HTTP Interface
The attribute HTTP Access Enabled allows a user to stop any access to a unit via the web
interface. The default value for this control is set to “yes”, which means that the unit can be
accessed using the web interface. If the option “No” is selected, then a warning is displayed as
shown in Figure 69.
8.3.10.2 Control Access to Telnet Interface
The attribute HTTP Telnet Enabled allows a user to stop any access to a unit via the telnet
interface. The default value for this control is set to “yes”, which means that the unit can be
accessed using the telnet interface20
8.3.10.3 SNMP (Simple Network Management Protocol)
The industry standard remote management technique is SNMP (Simple Network Management
Protocol). The PTP 500 Series Bridge supports version 1 and version 2c of the SNMP protocol.
8.3.10.4 Supported Management Information Bases (MIBS)
The PTP 500 Series Bridge SNMP stack currently supports the following MIBs:
•MIB-II, RFC-1213, The PTP 500 Series Bridge supports the ‘System Group’ and ‘Interfaces

SNMP State:The SNMP state attribute controls the creation of the SNMP features. Changing
the SNMP state attribute requires a mandatory reboot of the unit. Only when the SNMP state is
enabled at system start-up will the SNMP processor task be created.
SNMP Enabled Traps:The SNMP Enabled Traps attribute controls which SNMP Traps the
unit will send.

SNMP Community String:The SNMP community string acts like a password between the
networks SNMP management entity and the distributed SNMP clients (600 Series bridge). Only
if the community string is configured correctly on all SNMP entities can the flow of management
information take place. By convention the default value is set to ‘public’. When the community
string is changed the system requires a mandatory reboot before the new string or phrase is
adopted.
SNMP Port Number:Is the port the SNMP management agent is listening to for commands
from an SNMP manager. The default value for this port number is 161.
SNMP Trap IP Address:Is the address of either the network SNMP manager or Trap receiver.
When asynchronous events (traps in SNMP terminology) are generated, the client unicasts these
to this IP Address. When the address is changed the system requires a mandatory reboot before
the setting is adopted
SNMP Trap Port Number:The SNMP Trap Port Number is the port number of either the
networked SNMP manager or Trap receiver. By convention the default value for the port number
is 162. When the port number is changed the system requires a mandatory reboot before the
setting is adopted.
WiMAX Control:Enables and Disables the WiMAX (802.16) MIB. This control is only displayed
when ‘Fixed Frequency’ is selected during installation.

The SMTP client is an alternative method for the 500 Series bridge to alert a system administrator
when there are or have been system errors SMTP
Email Alert:This attribute controls the activation of the SMTP client.
SMTP Enabled Messages:The SMTP Enabled Messages attribute controls which email alerts
the unit will send.
SMTP IP Address:The IP address of the networked SMTP server.
SMTP Port Number:The SMTP Port Number is the port number used by the networked
SMTP server:By convention the default value for the port number is 25.
SMTP Source Email Address:The email address used by the 500 Series to log into the SMTP
server. This must be a valid email address that will be accepted by your SMTP Server.
SMTP Destination Email Address:The email address to which the 500 Series bridge will send
the alert messages.
8.3.10.8 SNTP (Simple Network Time Protocol)
The SNTP client allows the 500 Series to obtain accurate date and time updates from a networked
timeserver. The system time is used for SNMP and event logging.
SNTP State:When enabled, the Remote Management web page permits the following attributes
to be set.
Web Page Reference
116
SNTP IP Address:The IP Address of the networked SNTP Server.
SNTP Port Number:The port number of the networked SNTP server. By convention the default
value for the port number is 123.
SNTP Poll Interval:The period at which the SNTP client polls the server for time correction
updates. Default 1 hour. If for any reason an SNTP poll fails, the client will automatically perform
3 retries before waiting for the user defined poll period.
Time Zone:The time zone is a fixed offset from GMT that is added to the SNTP time to allow
the expression of time in all geographic time zones.
Daylight Saving:Allows a fixed offset of one hour to be added to the SNTP time in order to
reflect the local daylight saving time.
8.3.10.9 Setting the Clock
The PTP 500 Series bridge has a system clock which can be used to supply accurate date and
time information in the absence of a SNTP server. The system clock is battery backed and will
continue to operate for several days if the 500 Series bridge has been switched off.
SNTP State:If the SNTP State is set to “Disabled”, see Figure 68, then the Remote Manage-
ment web page allows the following attributes to be set:
Set Time:Shows the current time in 24 hour mode. The three editable fields display hours minutes
and seconds.
Set Date:Displays the current date. The year, month and day can be set using the drop-down
selection boxes.
Time Zone:See Section 8.3.10.9 “Setting The Clock”.
Daylight Saving:See Section 8.3.10.9 “Setting The Clock”
8.3.11 Diagnostics
To further enhance the diagnostic capabilities of the PTP 500 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 500 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
Web Page Reference
117
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.
8.3.11.1 Diagnostic Plotter
New for the PTP 500 Series is the system administration diagnostic plotter facility see Figure 71:
Figure 71 Diagnostic Plotter
The diagnostic plotter allows the system administrator to view the cascading histogram data in
an easily accessible graphical form. The plot always displays three traces, maximum, minimum
and mean by default. The diagnostic selector allows the user to select the various categories of
histogram.
The histograms that are available are:
•Vector Error
•Rx Power
•Tx Power
•Signal Strength Ratio
•Link Loss
•Rx Data Rate
Web Page Reference
118
•Tx Data Rate
•Aggregate Data Rate
The diagnostic plotter uses a novel time representation in the x-axis which compresses the timeline
of the plot without sacrificing resolution.
The trace selection allows the user to control which traces are plotted.
As with other management pages the page refresh period can be used to interactively monitor the
wireless link.
8.3.11.2 Diagnostics Download
The diagnostics Download page allows the system administrator to download snapshots of system
diagnostics.

9 Recovery Mode
The Motorola PTP 500 point-to-point wireless Ethernet bridges have a special mode of operation
that allows the user to recover a unit from configuration errors or software image corruption.
Recovery mode is entered by depressing the Recovery Switch located on the underside of the PIDU
Plus while applying mains power, as shown in Section 3.3.2 “PIDU Plus - PTP 500 Series Bridge”.
The Recovery Switch should be held in the depressed state for between 10 and 20 seconds after
the application of mains power. The Ethernet LED will flash with 10 double flashes at power up
(following the release of the Recovery switch).
When in recovery mode the user will be able to access the unit via the Ethernet interface. The
Ethernet interface will have its IP address set to 169.254.1.1 (or 10.10.10.10 see Section 7.7.10

Fault Finding
132
10 Fault Finding
If communication has been lost with the unit at the near end of the link then there may be a
hardware fault with the wiring, network or hardware. Go to the hardware section below. If
communication with the far end of the link is lost then go to the radio section below.
10.1 Hardware
If there are problems suspected with the link hardware the following procedure is recommended.
10.1.1 Power
Check the power LED at each end of the link. If the power lights are illuminated go to the Ethernet
section below. If at either end they are not illuminated then21 check the power source. If neither
is illuminated then there is no voltage on the power wires to the ODU.
•Check that the mains power is connected and switched on.
•Check that the power LED illuminates if the ODU connector is disconnected at the PIDU Plus
(Open the PIDU Plus flap on the left hand side).
If it does illuminate then either the ODU is drawing too much current, or the power wiring to the
ODU is short circuit or the PSU is supplying insufficient power. The likely fault can be determined
by removing the jumper (J906), found inside the removable cover of the PIDU Plus, and measuring
the current taken with an ammeter placed across the 2 jumper pins. This is normally 10mA without
the ODU connected and 300mA to 1A when the ODU is connected.
If it does not illuminate then recheck that power is applied to the PIDU Plus by measuring the
voltage across +55V and 0V pads inside the removable cover in the PIDU Plus. Check that the
PIDU Plus is not short circuit by measuring the impedance across the Power connector. Is the led
faulty?
10.1.2 Ethernet
The Ethernet LED is driven from the ODU processor and thus is capable of informing you of many
conditions using different flash sequences. If the Ethernet indicator does not illuminate at all there
are four possible conditions.
1. There is no power reaching the ODU because of a wiring fault
2. The ODU is faulty
3. The PIDU Plus is faulty
4. The Ethernet network side is faulty
Look at the following table to check the LED response for power up, disconnect the power and
reapply and note what happens.
The power indicator LED should be continually illuminated.
21
Fault Finding
133
Differentiating between 1-3 and 4 can be achieved by removing the power for 1 second. Watch
the Ethernet indicator for 1 minute while power is removed, if it never flashes then the problem is
1-3. Take the jumper (J905) out of the PIDU Plus and check the current taken by the ODU. This
should be 300mA to 1A when starting to run normally.
If the Ethernet indicator flashes to begin with but then stops flashing, the ODU is powered and
software loaded but Ethernet connectivity has been lost between the ODU and the users connected
equipment. All Ethernet connections should be rechecked.

10.1.3 Checking your wiring
If the above procedures fail to diagnose the issue you may have a wiring fault. Unplug the RJ45
from the PIDU+ and check the following resistances at the RJ45:
1. Check the cable resistance between pins 1 & 2, 3 & 6, 4 & 5 and 7 & 8 at the RJ45.
2. Check against column 2 in Table 17. Resistances for each pair should be within 1 ohm of each
other.
Fault Finding
134
3. Check the cable resistance between pins 1 & 3 at the RJ45. Check against column 3 in
Table 17.
4. Check the cable resistance between pins 4 & 7 at the RJ45. Check against column 4 in
Table 17.
5. Ensure that there is greater than 100K ohms between pins 1 & 8 for all cable lengths.
6. Ensure that there is greater than 100K ohms between pin 1 and ODU ground for all cable
lengths.
7. Ensure that there is greater than 100K ohms between pin 8 and ODU ground for all cable
lengths
10.2 Radio
10.2.1 No Activity
If communication over the radio link has been lost and the unit at the other end of the link can be
managed on its local network, the following procedure should be adopted: If there is no wireless
activity then the configuration should be checked. It is essential that the following items are
correct:
•Check for Alarm conditions on Home page
•Check that the software at each end of the link is the same version
•Check that the Target Mac address has not been misconfigured at each end of the link
•Check Range
•Check Tx Power
•Check License keys to ensure that both units are the same product variant
•Check Master/Slave status for each unit and ensure that one unit is Master and the other unit
is slave
•Check that the link has not been further obscured or the ODU misaligned
•Check the DFS page at each end of the link and establish that there is a quiet wireless channel
to use If there are no faults found in the configuration and there is absolutely no wireless signal
retry the installation procedure. If this doesn’t work then the ODU may be faulty.
10.2.2 Some Activity
If there is some activity but the link is unreliable or doesn’t achieve the data rates required then:
•Check that the interference has not increased using the i-DFS measurements
•If a quieter channel is available check that it is not barred
•Check that the path loss is low enough for the communication rates required
•Check that the ODU has not become misaligned
Lightning Protection
135
11 Lightning Protection
EMD (Lightning) damage is not covered under standard warranty The recommendations in this
user manual when installed correctly give the user the best protection from the harmful effects of
EMD. However 100% protection is neither implied nor possible.
11.1 Overview
The idea of lightning protection is to protect structures, equipment and people against lightning
by conducting the lightning current to ground via a separate preferential solid path.
The following should be treated as a guide only, the actual degree of lightning protection required
depends on local conditions and weather patterns and applicable local regulations.
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.
11.1.1 Lightning Protection Zones
The installation of the ODU can be classified into two different lightning protection zones.
Zone A - In this zone a direct lighting strike is possible. Zone B - In this zone a direct lightning
strike is unusual, but the full electromagnetic field is still present.
The zones are determined using the ‘rolling sphere method’, an imaginary sphere, typically 50
meter in radius is rolled over the structure. All structure points that contact the sphere, (Zone A)
indicate the zone where a direct strike is possible. Similarly points that do not contact the sphere
indicate a zone (zone B) where a direct strike is less likely.
The following diagrams (Figure 94 and Figure 95) show this zoning pictorially:
Equipment mounted in Zone A should be capable of carrying the full lightning current. Mounting of
the ODU in Zone A is not recommended. Mounting in Zone A should only be carried out observing
the rules governing installations in Zone A22 Failure to do so may put structures, equipment and
life at risk.
Equipment mounted in Zone B should be grounded using grounding wire of at least 10 AWG. This
grounding wire should be connected to a grounding rod or the building grounding system before
entry in to building.
The PTP 500 Series bridge ODU grounding point can be found on the bottom of the unit. The
600 Series Bridge is supplied with an appropriate grounding lug for attachment to the ODU.
Local regulations may also require the fitting of the 8 AWG ground wire referred below.

•Lightning protection: Motorola PTP-LPU - 2 per link (2 Motorola Kits, part number 2978)
•Grounding Stake
•RJ45 screened connectors
NOTE: There may be a local regulatory requirement to cross bond the CAT 5e cable at regular
intervals to the mast. This may be as frequent as every 10 meters (33 feet).

11.3.1 Pre-Power Testing
Before plugging the RJ45 from the lower LPU (or if not fitted the ODU) into the PIDU, check the
following resistances at the RJ45:
1. Check the cable resistance between pins 1&2, 3&6, 4&5 and 7&8 at the RJ45. Check against
column 2 in Table 17. Resistances for each pair should be within 1 ohm of each other.
2. Check the cable resistance between pins 1&3 and 4&7 at the RJ45. Check against columns 3
and 4 respectively in Table 17.
3. Ensure that there is greater than 100K ohms between pins 1&8 for all cable lengths.
4. Ensure that there is greater than 100K ohms between pin 1 and ODU ground for all cable
lengths.
5. Ensure that there is greater than 100K ohms between pin 8 and ODU ground for all cable
lengths.

11.3.2 Post-Power Testing
The Correct Operation is as follows:
Lightning Protection
141
1. Connect the RJ45 to the PIDU and apply power to the PIDU, the power LED should illuminate
continuously.
2. 30 seconds after powering, the Ethernet LED should be observed starting with 10 slow flashes.
3. If there is a network connection the Ethernet LED will then show Ethernet activity.
If the system does not operate corrctly, refer to the fault finding below.
The PIDU Green power LED does not illuminateUnplug the ODU connection from the
PIDU and check the power LED illumination. If the power LED still does not light then check the
power source.
The PIDU Green power LED flashesA flashing power LED indicates that there is a short
circuit on the output of the PIDU. Check that pins 4&5 and 7&8 are not crossed with pins 1&2
and 3&6 on the RJ45, and also greater than 100K ohms between pins 1&8.
The Ethernet LED flashes ten times but does not show Ethernet activityFailure of the
Ethernet LED to show Ethernet activity can be due to wiring to pins 1&2 and 3&6 being incorrect,
for example if the wiring to pins 1 and 3 are crossed.
The Ethernet connection to the network is only 10/100BaseT, when 1000BaseT was
expectedIt is likely there is a fault with the wiring to pins 4&5 and 7&8.
Lightning Protection
142
11.4 Locating the Fault
Having identified which of the wiring cores are likely to be connected incorrectly, the location of
the faulty cable can be narrowed by disconnecting sections of the drop cable and by unplugging
the relevant RJ45 connectors from the LPUs.
As a further aid to locating the fault the Ethernet connections are also available inside the LPU.
The connections can be accessed by rotating the LPU lid as shown in Figure 99 The Lid nut only
needs to be slacken, do not remove. Test point P1 on the LPU PCB corresponds to pin 1 on the
RJ45 etc.
An indication of power on the Ethernet cable is also provided inside the LPU, LED PWR1 will
illuminate in the case of the PTP600 series, LED PWR2 should not.

Wind Loading
143
12 Wind Loading
12.1 General
Antennas and electronic equipment mounted on towers or pole mounted on 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.
12.2 Calculation of Lateral Force
The 500 Series bridge 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 500 Series bridge (integrated or connectorized model) at
different wind speeds is shown in Table 18 and Table 19.

Note: When the connectorized version of 500 Series bridge is used with external antennas, the
figures from the antenna manufacturer for lateral force should be included to calculate to total
loading on the mounting structure.
12.3 Capabilities of the PTP 500 Series Bridges
The structure and mounting brackets of the PTP Series systems are capable of withstanding wind
speeds up to 151mph (242 kph). The installer should ensure that the structure to which the 500
Series Bridge is fixed to is also capable of withstanding the prevalent wind speeds and loads.

Installers are recommended to contact the national meteorological office for the country concerned
to identify the likely wind speeds prevalent at the proposed location. This will enable the installer
to estimate the total wind loading on the support structures.
Examples of the sort of statistics that are available are:

13 PTP 500 Series Bridge - Connectorized Model
13.1 Scope
This section details the changes and additional features relevant to the connectorized version of
the PTP 500 Series products..
13.2 Product Description
13.2.1 Hardware
The Connectorized PTP 500 Series Bridge is a variant designed to provide the system integrator
and installer with the ability to provide extra capability to cope with very difficult radio links
compared to the PTP 500 Series Integrated model. The variant allows the use of a variety of
externally mounted antennas, either Flat Plate or Dish, which have higher gains than provided by
the integrated antenna that is normally used.
Figure 100 Connectorized 500 Series Bridge Outdoor Unit
13.2.2 Antenna Choices – 5.8 GHz
The integrated antenna has a gain of 23.5 dBi.
PTP 500 Series Bridge - Connectorized Model
146
In non-FCC regions antenna choice is not restricted but any region specific EIRP limit must be
obeyed by reducing the maximum Transmit power23, see Table 6 in Section 5.2 “Region Codes”.
In FCC regions external antennas from the list in Section 13.6.3 “Antennas for USA / Canada –
5.8 GHz” can be used with the Connectorized version of the 500 Series Bridge. These are approved
by the FCC for use with the product and are basically constrained by the following limits:
•Single Polarization Flat Plate Antennas – up to 28 dBi per antenna.
•Single/Dual Polarization Parabolic Dish Antennas – up to 37.7 dBi per polarization or antenna.
In FCC regions when using external antennas – cable loss between the connectorized version of
the 500 Series Bridge and the antenna ports must not be less than 1.2 dB.
13.2.3 Antenna Choices – 5.4 GHz
The integrated antenna has a gain of 23.5 dBi.
In FCC regions external antennas from the list in Section 13.2.3 “Antenna Choices – 5.4 GHz”
can be used with the Connectorized version of the 500 Series Bridge. These are approved by the
FCC for use with the product and are basically constrained by the following limits:
•Single/Dual Polarization Parabolic Dish Antennas – up to 34.6 dBi 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 version of the
500 Series Bridge and the antenna ports must not be less than 1.2 dB.
13.3 Software/Features
The connectorized variant operates in the same way as the basic 500 Series and is released initially
with the feature set to the Connectorized 500 Series variant. The areas where the functionality is
modified are:
13.3.1 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 500 Series Bridge 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.
Maximum Transmit Power Allowed = EIRP Limit – Antenna Gain + Cable Losses; set the power to the 1dB value
23
lower than the actual value calculated.

13.3.3 Installation Pages
The installer is prompted to enter the Antenna Gain and Cable Loss (Connectorized PTP 500 Series
Bridge to antenna) at each end of the link. The Installation Page(s) is shown as Figure 103 to
Figure 105.

a significant difference in length of the antenna cables for the two antenna ports, then the average
value should be entered.

Spectrum Management Control:Is used to configure the 500 Series Bridge Spectrum Man-
agement features, see Section 8.3.7 for more details. iDFS is the abbreviation for intelligent
Dynamic Frequency Selection, which continually monitors the spectrum looking for the channel
with the lowest level of on channel and co-channel interference. Fixed frequency mode allows
the installer to fix the Transmit and receive frequencies on the units. The frequencies may be
configured symmetrically or asymmetrically.

EIRP:The Confirm Installation Page displays the EIRP (Effective Isotropic Radiated Power),
which describes the strength of the radio signal leaving the wireless unit. This allows the operator
to verify that their link configuration (Max Transmit Power, Antenna Gain and Cable Loss) do
not cause the link to exceed any applicable regulatory limit.
Figure 105 Connectorized 500 Series bridge ‘Disarm Installation’ Page
13.4 Deployment Considerations
The majority of radio links can be successfully deployed with the 500 Series. It should only be
necessary to use external antennas where the Link Estimator indicates marginal performance for a
PTP 500 Series Bridge - Connectorized Model
151
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.
Dual polarization antennas (with a gain greater than the integrated antenna) are currently only
available in parabolic dish form.
13.5 Link Budget
An estimate of the link budget for a specific application can be obtained by using the Motorola
Systems link estimation tools. For more information see the Motorola web site.
13.6 Regulatory Issues
Installations must conform to any applicable local regulations for the Equivalent Isotropic Radiated
Power (EIRP).
Ensuring compliance becomes more complex when the connectorized unit is used with external
antennas which may be locally sourced. With higher gain external antennas fitted, the Maximum
Transmit power may need to be reduced for operation in specific countries.
See table in Section 5.2 for any EIRP restrictions that may apply in your region.
In some regions, operation of the PTP54500 products is constrained by an EIRP limit. The normal
constraint is that the EIRP does not exceed 30 dBm (33 dBm for PTP58500) for radio signals with
a bandwidth of >=20 MHz. As the PTP54500 operating bandwidth is approximately 27 MHz,
then the limit is 30 dBm EIRP (33 dBm for PTP58500).
When operating with external antennas, the installer/operator has to set the maximum transmit
power to ensure that the EIRP limit is not exceeded. The Set_Max_Transmit_Power is calculated
as below:
Set_Max_Transmit_Power = [Max_Transmit_Power] rounded down to nearest lower dB.
13.6.1 Antenna Choice (FCC and Industry Canada Regions Only)
The antennas which can be deployed with the Connectorized 500 Series Bridge are shown in
Section 13.6.3 “Antennas for USA / Canada – 5.8 GHz” and Section 13.6.4 “Antennas for
USA / Canada – 5.4 GHz”.
For FCC and Industry Canada, the PTP500 Series Bridge has been designated to operate with the
antennas listed in Section 13.6.3 “Antennas for USA / Canada – 5.8 GHz” and Section 13.6.4
“Antennas for USA / Canada – 5.4 GHz”, and having a maximum gain of 37.7 dB (34.9 dB for
5.4 GHz product variant). Antennas not included in these tables or having a gain greater than
37.7 dB (34.9 dB for 5.4 GHz product variant) are strictly prohibited for use with this device. The
required antenna impedance is 50 ohms.

13.6.2 Cable Losses (FCC Regions Only)
The FCC approval for the product is based on tests with a cable loss between the units of ap-
proximately 1.2dB at 5.8GHz. The use of lower cable losses would result in the installation being
outside the FCC rules.
As an indication, 1.2dB of cable loss corresponds to the following cable lengths excluding connector
losses (source: Times Microwave).

13.7 Installation
The section covers the generic installation instructions for the Connectorized versions of the PTP
500 Series point-to-point wireless Ethernet bridges. The actual installation procedure will depend
on antenna choice, cable choice, required antenna separation etc.
13.7.1 Antenna Choice
Section 13.6.3 “Antennas for USA / Canada – 5.8 GHz” and Section 13.6.4 “Antennas for USA
/ Canada – 5.4 GHz” show a wide variety of antennas that can be used with the Connectorized PTP
PTP 500 Series Bridge - Connectorized Model
159
500 Series bridge. The main selection criteria will be the required antenna gain. The secondary
criteria should be 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.
13.7.2 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 500 Series bridge 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.
13.7.3 Tools
The tools required for mounting a Connectorized 500 Series bridge unit are the same as those
required for an Integrated 500 Series bridge detailed in Section 7.3. The tools required for
mounting the antennas are specific to the antenna chosen. The installer should refer to the antenna
manufacturer’s instructions.
13.7.4 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
13.7.5 Mounting the Connectorized 500 Series Bridge
A Connectorized 500 Series bridge is shipped with the same bracket as supplied with an Integrated
unit. Details on the use of this bracket can be found in Section 3.3.7. The 500 Series Bridge 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 500 Series bridge 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 Section 13.6.3 “Antennas for USA
/ Canada – 5.8 GHz” .
When using separate antennas the Connectorized 500 Series Bridge 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 500 Series Bridge at the mid point between the antennas.
PTP 500 Series Bridge - Connectorized Model
160
13.7.6 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.
13.7.7 Alignment Process
When aligning antennas deployed with a Connectorized 500 Series bridge 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.
Tip: 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.
13.7.8 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 Section 7.7.11 “Aligning the PTP 500 Series
Bridge ODUs”.
13.7.9 Aligning Separate Antennas
When using separate antennas to achieve spatial diversity, one should be mounted with Horizontal
polarization and the other with Vertical polarization.
The following steps should be followed:
Step 1: Mount the Antennas
Step 2: Mount the connectorized version of the PTP 500 Series Bridge unit
Step 3: Route and make off the ends of the Antenna cables
Step 4: Connect the antenna cables at the antennas
Step 5: Connect one of the antenna cables at the Connectorized version of the 500 Series bridge
unit.
Step 6: Connect the Connectorized 500 Series Bridge ODU to PIDU Plus cable and configure the
unit as described in Section 7.7 “Connecting Up”.
Step 7: Align the connected antenna using the tones as described in Section 7.7.11 “Aligning
the PTP 500 Series Bridge ODUs”.
Step 8: Connect the other antenna to the Connectorized 500 Series bridge.
Step 9: Disconnect the cable to the already aligned antenna.
Step 10: Align the second antenna using the tones as described in Section 7.7.11 “Aligning the
PTP 500 Series Bridge ODUs”.
Step 11: Re-connect the second antenna to the Connectorized 500 Series bridge (Note: you will
notice the tone pitch increase as you re-connect the second antenna due to the additional received
signal).
Step 12: Use the relevant status web pages to check that you are getting the results you expect
from your link planning.
Step 13: Complete the installation as detailed below.
PTP 500 Series Bridge - Connectorized Model
161
13.7.10 Completing the Installation
The installation should be completed by checking all mounting nuts bolts and screws, securing all
cables and weatherproofing the installation. Warning: 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.
13.7.11 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 500 Series
bridge 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.
13.7.12 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.

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 107 shows this diagrammatically for the 500 Series bridge 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.

14 Data Rate Calculations
To aid the calculation of data rate throughput, the following plots of throughput verses link range
have been produced for all the PTP 500 Series modulation modes, assuming the units are connected
using 100 Mbps Ethernet. Please note that only 15 MHz channel bandwidth has been considered
and the plots are the same for IP or TDM modes. Aggregate data rate capacity can be calculated
using four key system parameters:
•Receive modulation mode
•Transmit modulation mode
•Range Between the two wireless units
•Wireless link mode (IP or TDM) Using these parameters the Receive and Transmit data rates
can be looked up using the plots Figure 111 through Figure 125.

AES Encryption Upgrade
172
15 AES Encryption Upgrade
The Motorola PTP 500 Series bridges support link encryption using the NIST approved Advanced
Encryption Standard, HFIPS-197 UTH. This standard specifies AES (Rijndael) as a FIPS-approved
symmetric encryption algorithm that may be used by U.S. Government organizations (and others)
to protect sensitive information.
Link Encryption is not available in the standard PTP 500 Series system. A license key to enable link
encryption can be purchased from your Motorola Point-to-Point Distributor or Solutions Provider.
AES can be activated on receipt of the activation on the Motorola Systems Support Page.
There are two levels of encryption that are available to purchase:
•128-bit
•128 and 256-bit
Option 1 allows the user to encrypt all traffic sent over the wireless link using 128-bit encryption.
Option 2 allows the user to encrypt traffic using either 128 or 256-bit encryption. The configuration
process for both encryption variants is identical except for the selection of algorithm. The following
configuration example is for a 256-bit encryption key.
15.1 Configuring Link Encryption
After purchasing AES encryption for the PTP 500 Series wireless link, two new license keys will
be issued, one for each end of the wireless link. The following configuration process gives a step
by step guide to enabling AES link encryption on a PTP 500 Series bridge.
15.1.1 License Keys
The first step when configuring link encryption is to enter the new license keys in both 500 Series
wireless units.
Figure 126 shows the license key data entry screen. This screen can only be accessed by the
system administrator. If you do not have access to the PTP 500 Series system administration
pages then please contact your designated system administrator.
It must be noted that configuring link encryption will necessitate a 500 Series bridge service outage.
Therefore it is recommended that the configuration process be scheduled during an appropriate
period of low link utilization. Motorola recommends the following process for entering new license
keys and minimizing service outage.
1. Open two browsers, one for each end of the link
2. Navigate to the ‘License Key’ data entry page for each end of the link
3. Enter the license keys and click the ‘Validate license key’ button at each end of the link. This
will allow the software to validate the license key prior to the system reset. (DO NOT CLICK
ARE YOU SURE POPUP DIALOG)
AES Encryption Upgrade
173
Figure 126 AES Software License Key Data Entry
4. When both license keys have been successfully validated confirm the reboot for both ends of
the link. The software is designed to allow five seconds so that a user can command both ends
of the link to reset before the wireless link drops.
5. The link will automatically re-establish.
15.1.2 Encryption Mode and Key
Entering the license keys only does not initialize AES link encryption. Link encryption can only
be enabled via the Configuration or Installation Wizard pages. Motorola recommends that the
Configuration page Figure 127 be used to configure AES link encryption.
AES Encryption Upgrade
174
Figure 127 AES Configuration Data Entry Page
Motorola recommends the following process for entering AES link encryption configuration:-
1. Open two browsers, one for each end of the link
2. Navigate to the ‘Configuration’ data entry page for each end of the link
3. At both ends of the link select the ‘AES (Rijndael)’ Encryption Algorithm required.
4. At both ends of the link enter ether an 128-bit or 256-bit encryption key. Note the key consists
of 32/64 case insensitive hexadecimal characters. The same Key must be entered at both ends
of the link. Failure to enter the same key will cause the link to fail.
AES Encryption Upgrade
175
5. Submit configuration on both ends of the link, but do not reboot.
6. Reboot both ends of the link Figure 128. The software is designed to allow five seconds so
that a user can command both ends of the link to reboot before the wireless link drops.
Figure 128 Configuration Reboot Screen
15.2 Wireless Link Encryption FAQ
15.2.1 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.
15.2.2 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.
15.2.3 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.

FAQs

18 FAQs
Can I source and use my own PoE adaptor with the 500 Series bridge? No. The 500
Series bridge 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 500 Series bridge? The 500 Series bridge is the first product
to feature Multiple-Input Multiple-Output (MIMO). The PTP 500 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 500 Series bridge 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, i.e., 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 500 Series bridge ? There are many special features built-in
to the hardware of the 500 Series bridge. The product offers the highest system gain in its class
through high sensitivity antennas for improved signal recovery. It also features a Software Defined
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 500 Series
bridge has a built-in web server for advanced management capabilities including detailed radio
signal diagnosis.
In which frequency bands does the 500 Series bridge operate? The Motorola point-to-
point 500 Series bridge operates in the unlicensed 5.4 GHz (ETSI Band B) and 5.8 GHz (ETSI
Band C and FCC ISM band). This means no license is required to operate the 500 Series bridge.
Why does the 500 Series bridge 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.
Is the 500 Series bridge an 802.11a device?No, although similar, the 500 Series bridge uses
different encoding and radio transmission systems from 802.11a. In areas where 802.11a systems
are operating, the 500 Series bridge will detect the 802.11a radio signals and choose a clear channel
away from any interference.
How much power does the 500 Series bridge transmit?At all times the 500 Series bridge
operates within country / region specific regulations for radio power emissions. In addition, the
500 Series bridge 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 500 Series Bridge avoid interference from other devices nearby?
At initialization, the 500 Series bridge monitors the available frequency channels to find a channel

that is clear of interference. In operation 500 Series bridge continuously monitors the spectrum to
ensure it is operating on the cleanest channel.
How does the 500 Series bridge integrate into my data network?The 500 Series bridge
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 500 Series bridge 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 500 Series bridge provide security for data traffic?The 500 Series bridge
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 500 Series bridge?Yes,
but there are some restrictions. Mozilla 1.6 or higher is recommended.
