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 band in which the system operates is ‘unlicensed’ (except from the 4.9 Ghz product) and
the system can be used provided it does not cause interference. Further, it is not guaranteed
protection against interference from other products and installations.
2
The system has basically 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 as well as comparable
regulations in other countries. This equipment generates uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur in a particular
installation.
If this equipment does cause harmful interference to other equipment, 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 equipment and ODU.
• Connect the equipment into a power outlet on a circuit different from that to which the
receiver is connected.
Consult your installer or supplier for help.
Deployment and Operation
The Radio Regulations of various countries’ limits constrain the operation of radio products generally.
In particular the local regulator may limit the amount of conducted or radiated transmitter power and
may require registration of the radio link.
The power transmitted by the PTP 400 Series 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. Footnotes to the table below 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 400 family of
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. In the case of the
reflector, the distance is even more conservative because the equation used models the
reflector as a point source and ignores its physical dimensions.
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/rpb 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.

Notes:
1. The regulations cover the power averaged over a 6 minute period.
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 5.7GHz.
3. At 5.7GHz, for antennas between 2ft and 6ft, alter the distance proportionally to the
antenna gain.

3 Getting Started
3.1 For Your Safety
WARNING: Use extreme care when installing antennas near power lines.
WARNING: Use extreme care when working at heights.
WARNING: The Outdoor unit (ODU) for the PTP 400 Series Bridge must be properly
grounded to protect against lightning. 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 Canadian Electrical Code. These codes describe correct installation
procedures for grounding the ODU, mast, lead-in wire and discharge unit, size of grounding
conductors and connection requirements for grounding electrodes. It is recommended that
installation of the ODU be contracted to a professional installer.
WARNING: The ODU for the PTP 400 Series Bridge MUST be grounded to a Protective
Earth as described in Section 7.7.5 “Grounding the Installation” of this Installation Manual and
in accordance with the Local Electrical Regulations.
WARNING: It is recommended that the supplied Power Indoor Plus (PIDU Plus) – PTP 400
Series is used to power the PTP 400 Series Bridge ODU. The use of other power sources
may invalidate safety approval and affect your warranty.
WARNING: When using alternate DC supplies (via the PIDU Plus DC in terminals as
described in Section 3.3.3 ”Redundancy and Alternate Powering Configurations”), such as
battery-backed DC power source, the supply MUST comply with the following requirements:
• The voltage and polarity is correct and is applied to the correct terminals in the PTP 400
Series Bridge PIDU Plus
• The power source is rated as SELV
• The power source is rated to supply at least 1A continuously, and
• 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)
CAUTION: 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.
CAUTION: Users and installers should note that in an emergency the mains power supply is
the primary disconnect device.
23
CAUTION: Safety will be compromised if external quality cables are not used for connections
that will be exposed to the weather.
CAUTION: Safety will be compromised if a different power supply is used than the one
supplied by Motorola as part of the system. This will also invalidate your warranty.

3.3 Product Description
This User Manual is specifically written for the PTP 400 Series of point-to-point broadband
wireless solutions. The PTP 400 Series Bridge has been developed to provide Point-to-Point
data connectivity via a 4.9 GHz, 5.4 GHz or 5.8 GHz wireless Ethernet bridge operating at
broadband data rates. The PTP 400 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 400 Series Bridge Deployment
The PTP 400 Series Bridge offers true non-line-of-sight (NLOS) operation by using a
combination of Orthogonal Frequency Division Multiplex (OFDM) modulation and Multiple-In
Multiple-Out (MIMO) techniques. These technologies enable the PTP 400 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 400 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.
26
Each end of the link consists of:
• An integrated 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. Hereafter referred to as the Power Indoor Unit Plus (PIDU Plus).
• Units will normally be supplied pre-configured as a link.
Power is fed into the PIDU Plus from the mains via a standard “figure of eight” mains plug.
The network connection is presented to the user at the PIDU Plus via an RJ45 socket.
Connection between the ODU and PIDU Plus is made using standard shielded CAT5 UV
resistant cable. The spare twisted pairs of the cable are used to feed power from the PIDU
Plus to the ODU.
27
3.3.1 The Outdoor Unit (ODU)
The ODU (Figure 2) is a self-contained unit. It houses both radio and networking electronics.
Also shown in Figure 2 is a Lightning protection unit, see Section 11 “Lightning Protection”. A
single CAT 5 cable feeds the unit. Power is fed to the unit via the brown/brown white pair
connected to pins 7 and 8 and the blue/blue white pair connected to pins 4 and 5 of the RJ45
plugs and sockets employed. It should be noted that this powering arrangement is not
standard Power over Ethernet (PoE). The ODU for the PTP 400 Series Bridge should only be
deployed using the supplied PTP 400 Series Bridge Power Indoor Unit (PIDU Plus).
WARNING: All four power conductors MUST be connected.
Figure 2 - PTP 400 Series Bridge Outdoor Unit (ODU)
28
3.3.2 The PIDU Plus – PTP 400 Series
The PTP 400 Series Bridge PIDU Plus is used to generate the ODU supply voltage from the
mains supply. The PIDU Plus also houses a status indicator driven from the ODU.
Figure 3 - Power Indoor Unit (PIDU Plus) – PTP 400 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 9 for further fault finding information.
The bottom of the PIDU Plus houses the Ethernet connection via RJ-45 socket, an entry point
for the PIDU Plus/ODU cabling and the Recovery Switch.

settings remain the same.
Table 5 - Reset Actions
On the left side of the PIDU Plus 48V DC input and output connections can be found. These
are used to power the PTP 400 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”. The DC input range is 36-60V. The ODU requires 36V to operate
so care should be taken to account for voltage drop over the ODU to PIDU Plus cable.
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 PTP 400
Series Bridge PIDU Plus
• The power source is rated as SELV
• The power source is rated to supply at least 1A continuously, and
• 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 400 Series Bridge PIDU Plus connects 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 PTP 400 Series Bridge PIDU Plus is 100V-240V AC, 47-63Hz.
Mains connection to the PTP 400 Series Bridge PIDU Plus is made using a standard “figure
of eight” mains lead as shown in Figure 5.

3.3.5 Cables and Connectors
The cable used to connect the PTP 400 Series PIDU Plus to the ODU can be any standard
CAT 5 type provided that it is suitable for outdoor deployment. Motorola recommends that
cables to the specification below be used.
NEC/CEC: CMR (ETL) C (ETL) 75C SUN RES OIL RES II
Failure to use the recommended (or equivalent) standard of cable may invalidate the
system’s safety certification.
The PIDU Plus/ODU cable 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”.
33
The connection between the PTP 400 Series Bridge PIDU Plus and the user’s equipment can
be made using any standard CAT5 patch cable. The RJ45 Ethernet connection is presented
as a piece of network equipment. However as automatic MDI/MDI-X sensing and pair
swapping is employed a crossed Ethernet patch cable can be used for connection to another
piece of networking equipment or directly to end user equipment.
It should be noted that the PIDU Plus provides continuity between the screen on the ODU to
PIDU Plus cable and screen on the PIDU Plus-User equipment cable. If continuity of the
screening is desired from the ODU to the PIDU Plus to the user’s equipment, CAT5 STP
cable and connectors should be used for the latter connection. CAT5 STP cable between the
PIDU Plus and the user’s equipment will provide additional protection against surges induced
on the Ethernet connections.
3.3.6 Surge Arrestor
The PTP 400 Series Bridge PIDU Plus does not provide lightning or surge suppression.
Should lightning or surge suppression be required a separate Ethernet surge suppressor
should be used and appropriately earthed. Suitable surge suppressors can be sourced from
your Motorola Point-to-Point Distributor or Solutions Provider. The ODU is protected by built-
in surge suppression as standard. See 11 “Lightning Protection”.
3.3.7 Mounting Brackets
The PTP 400 Series Bridge is supplied with a mounting bracket suitable for mounting the
ODU to a pole of 25mm (1”) 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 PIDU Plus can either be desk or wall mounted. The preference is wall mounted with the
cables dressed to a cable channel. Remember to leave space for access to the recovery
button. See section 7.7.6.
34
3.3.8 Configuration and Management
Configuration and Management of the PTP 400 Series Bridge is implemented using an inbuilt
web server hosting a number of Configuration and Management web pages. This approach
allows Configuration and Management to be carried out on any standard web browsing
technology. The PTP 400 Series Bridge can also be managed remotely using the SNMP
management protocol. Connection 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”.

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 400 Series Bridge has been developed to operate within a selection of frequency
bands.
The current product range supports:
• USA 4.9 GHz National Public Safety Band (4.940-4.990 GHz) - 49400
• ETSI 5.4 GHz license exempt band B (5.470-5.725 GHz) - 54400
• ETSI 5.8 GHz license exempt band C (5.725-5.850 GHz) and the USA 5 GHz ISM band
(5.725-5.850 GHz) - 58400
The PTP 400 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), Planned Frequency
Allocation or Dynamic Frequency Selection (DFS) 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. To the data network the
PTP 400 Series Bridge is implemented as a learning bridge. A learning bridge builds up a
picture of which addresses are connected to which port. This means that it will not bridge a
packet if it knows that the destination address is connected to the same port on which the
bridge saw the packet. Figure 10 illustrates the PTP 400 Series Bridge layer diagram.
36
Figure 10 - PTP 400 Series Bridge Layer Diagram
The PTP 400 Series Bridge functionality has been extended to encompass the specification
IEEE 802.1p. IEEE 802.1p and uses Ethernet packets extended by 4 bytes, as specified in
IEEE 802.1q for VLAN tagging, to prioritize packets over the wireless interface. The PTP 400
Series Bridge will forward all VLAN tagged packets regardless of the VLAN ID value.
Each unit in the link is manageable through an IP connection. Standard IP protocols are
utilized for all management functions e.g. HTTP, SNMP, etc.
The PTP 400 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 8.3.7 “Software Upgrade”. Once the image transfer has completed successfully the
image is written to 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 image
installed during manufacturing to allow the unit to be recovered.

5 General Considerations
5.1 Spectrum Planning
The PTP 400 Series Bridge has three frequency variants in its product range.
Band Definition Frequency
Coverage
Channel
Width
Channel
Raster
4.9 GHz USA National Public Safety Band 4940-4990 MHz 10 MHz 5 MHz
5.4 GHz ETSI 5 GHz band B 5470-5725 MHz 11 MHz 12 MHz
5.8 GHz USA ISM Band / ETSI 5 GHz band C 5725-5850 MHz 11 MHz 6 MHz
Table 6 - PTP 400 Series Bridge Frequency Variants
There are two distinct approaches to spectrum planning:
First, an operator can utilize the default spectrum management mode i-DFS (intelligent
Dynamic Frequency Selection). This mode uses the PTP 400 Series Bridge’s ability to
measure the interference levels in all channels to build up a picture of the interference / noise
levels in all channels. The PTP 400 Series Bridge uses statistical techniques to select the
most appropriate 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 8.3.8 “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 400 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.

When shipped from the factory, units are configured as follows:
• 4.9 GHz PTP 400 Series Bridge – Region Code 14
• 5.4 GHz PTP 400 Series Bridge – Region Code 9
• 5.8 GHz PTP 400 Series Bridge – Region Code 1
WARNING To meet the regulatory requirements of your region you should set the correct
Region Code by obtaining a new License Key from you 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.
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
interference 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.
40
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 dependant on the channel raster selected.
For example see the effect of the UK RTTT channel restrictions in Figure 11. Barred channels
are indicated by a “No Entry” symbols displayed on the “Spectrum Management” web page,
see section 8.3.10 “Spectrum Management Control - With Operational Restrictions ”.

frequencies. See Figure 12.
5.4.2 Fixed Frequency Operation
When operating in ‘Fixed Frequency’ mode (see section 8.3.5.3 “Wireless Configuration”) the
operator can set the operating frequency independently in both directions to any of the center
frequencies available in i-DFS mode.

5.4.3 Transmit Power Reduction at the Band Edges
The 4.9 GHz variant does not apply any band edge power reduction.
5.5 5.4 GHz Specific Frequency Planning Considerations
To fully utilize the 5.470 to 5.725 GHz of allocated spectrum the operator must adjust the
lower center frequency attribute in the installation wizard, described in detail in 8.3.5 “Install
Wizard Pages” Adjustment of the lower center frequency allows the operator to slide the
available frequency settings up and down the 5.4 GHz band. See Figure 13.

5.5.1 Raster Considerations
The PTP 400 Series bridge 5.4 GHz variant operates on a 12 MHz channel raster that is set
to odd center frequencies. See Figure 13.
5.5.2 Fixed Frequency Operation
When operating in ‘Fixed Frequency’ mode (see section 8.3.5.3 “Wireless Configuration”) the
operator can set the operating frequency independently in both directions to any of the center
frequencies available in i-DFS mode using the ‘Default Raster’ setting. For the expert user
further granularity can be obtained by turning off the ‘Default Raster’. In this mode the
operator is able to select any odd frequency that sets the channel in-band.

5.6.1 Raster Considerations
The PTP 400 Series Bridge 5.8 GHz variant operates on a 6 MHz channel raster that is set to
even center frequencies. see Figure 14.
5.6.2 Fixed Frequency Operation
When operating in ‘Fixed Frequency’ mode (see section 8.3.5.3 “Wireless Configuration”) the
operator can set the operating frequency independently in both directions to any of the center
frequencies available in i-DFS mode using the ‘Default Raster’ setting. For the expert user
further granularity can be obtained by turning off the ‘Default Raster’. In this mode the
operator is able to select any even frequency that sets the channel in-band.
5.6.3 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 400 Series Bridge reduces the power when operating at the
edge channels. The amount of reduction if any is dependant on the local regulator authority of
the region of operation. These currently only affect systems configured with Region Code 1.
The power reduction in the edge channels is presented in Figure 15.

5.7 Distance
The PTP 400 Series Bridge will operate at ranges from 100 m (330 feet) to 200 km (124
miles), within four modes 0-5km, 0-40km, 0-100km and 0-200km. 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 feet) 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 400 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
The amount of lightning protection is dependent on regulatory requirements and the end user
requirements. The standard ODU for the PTP 400 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 surge arrestor to protect connected equipment from nearby strikes.
The PTP 400 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”.
44
5.10 Electrical Requirements
The PTP 400 Series Bridge is supplied with a variable input voltage (90-264V, 47-63Hz AC)
inline power supply unit which is incorporated into the PTP 400 Series Power Indoor Unit
(PIDU Plus). The PTP 400 Series Bridge requires one mains supply outlet at each end of the
link.
Alternately, the PTP 400 Series Bridge may be powered by a DC supply (45-55V) though the
terminals provided under the left cover on the PIDU Plus.
45
6 Site Planning
6.1 Site Selection Criteria
The following are guidelines for selecting the installation location of the ODU and PIDU Plus
for the PTP 400 Series Bridge.
6.1.1 ODU Site Selection
When selecting a site for the ODU the following should be taken into consideration:
• That 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
• Protection from the weather
• Aesthetics and planning permission issues
• Distance from the PIDU Plus and connected equipment (Maximum cable run ODU to
connected equipment is 100m [330 feet])
• Distance from the PIDU Plus to the ODU (Maximum cable run from the PIDU Plus to the
ODU is 100m [330 feet] minus the length of the cable from the PIDU Plus to the
connected equipment)
6.1.2 PTP 400 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 reset switch (See section 3.3.2
“The Power Indoor Unit (PIDU Plus)” and section 9 “Fault Finding”
46
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).

6.1.4 Aggregate Ethernet throughput rate versus maximum link loss
The equipment capability is given in Table 8 and Table 9. It gives the Ethernet throughput
rate versus link loss for the PTP 400 Series Bridge in both modes. 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 1 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.
The full calculation is relatively complicated and thus Motorola has supplied a PTP Link
Estimator that calculates the radio propagation and reliability of NLOS links using the PTP
400 Series Bridge equipment.

A Frequently Asked Questions (FAQ) section can be found in section 16.
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 400
SERIES PRODUCT.
7.6 Mounting the ODUs
The ODU mounting bracket is designed to ease installation by fixing the bracket to the 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 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 16.
51
Figure 16 - Mounting to pole diameters 25mm (1”) to 50mm (2”)
When adjustment is complete tighten all bolts to 14Nm (11 lb ft).
Warning: Do not over tighten the bolts as bracket failure may occur.
The enclosure and mounting brackets of the PTP 400 Series Bridge are capable of
withstanding wind speeds up to 150mph (242kph). The installer should ensure that the
structure to which the bridge is fixed 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 17 - Integral Safety Loop
52
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 Cable — RJ45 connections
Cables should be prepared using the following instructions along with the cable and
connector supplier’s instructions:
Step 1: Assemble gland Step on cable as
shown
Step 2: Strip the outer insulation
Step 3: Arrange conductors as shown in
Figure 19 and cut to length
Step 4: Insert conductors and crimp
53
Figure 18 - Completed ODU connector
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.
Note: The PIDU Plus end of the cable does not employ a cable gland.
Figure 19 - RJ45 Pin Connection
54
7.7.2 Making the 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 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
Figure 20 - Connections at the ODU
55
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 21 - Disconnecting the ODU
Warning: Ensure that power is removed from the system at the PIDU Plus to prevent damage
to the ODU while making or breaking the connection.
7.7.3 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.
7.7.4 Fitting A Surge Arrestor
If you have opted to fit a Surge Arrestor, this should be installed by following the
manufacturer’s instructions. For recommended types see Section 11 “Lightning Protection”
56
7.7.5 Grounding the Installation
The Outdoor Unit (ODU) for the PTP 400 Series Bridge 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
Canadian Electrical Code or 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. See Section 11 “Lightning Protection” for recommended grounding
kits. Failure to follow these Lightning Protection recommendations will invalidate your
warranty if damage to the system is found to be caused by lightning.
7.7.6 Making the ODU Connection at the PTP 400 Series Bridge PIDU Plus
The ODU is connected to the PIDU Plus by means of a concealed RJ45 connector. The RJ45
connection has been placed inside the PIDU Plus hinged cover to prevent the user
inadvertently plugging other equipment into the ODU RJ45 socket.
Warning: 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 100BaseT
connection between the PIDU Plus and 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 to PIDU Plus Cable
ensuring that it snaps home
57
Step 3: Replace the cover and secure with the retaining screw
7.7.7 Making the Network Connection at the PIDU Plus – PTP 400 Series
The Network connection is made by connecting the user’s Network Equipment directly to the
PIDU Plus LAN port as shown in Figure 22.
Figure 22 - Making the Network Connection at the PTP 400 Series Bridge PIDU Plus
58
7.7.8 Mounting the PTP 400 Series Bridge PIDU Plus
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 reset switch can be accessed when mounting the unit.
Step 1: Fix the PIDU Plus to the wall using the lugs provided.
Step 2: Make connections as per Section 7.7.6
WARNING: 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 23. 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 23 - PTP 400 Series Bridge PIDU Plus Drip Loop Configuration
WARNING: 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.
WARNING: Some network operators employ gel filled cables to get around the problem of
moisture ingress and transmission. The PTP 400 Series Bridge has NOT been tested using
these cables. Use of gel filled cables may affect the performance of PTP 400 Series Bridges.
60
7.7.9 Powering Up
The PTP 400 Series Bridge is supplied as a pair of matched Master/Slave units. The Master
unit to be configured 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 400 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 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 8.3.5. This process will give the installer the opportunity to set the unit’s IP
address to one that is in the desired address range and set each unit up with the MAC
address of its peer unit ready to establish a radio link. 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 10.10.10.10
(Slave) and 10.10.10.11 (Master). 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.
61
7.7.10 Aligning the PTP 400 Series 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 400 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 achieved13. The tones and their meanings are as follows:
State Name Tone Description State Description Pitch Indication
(Higher pitch = higher
power)
Band Scan 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 10 - 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 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.
13 The pitch of the alignment tone is proportional to the power of the received wireless signals. The
best results are usually achieved by making small incremental movement in angular alignment.
62
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 Scanning state with the pitch of the tone set be the background
noise level. Alignment of the unit should cease during this time.
The master unit can take between 30 seconds in 0-5km (0-3 miles) mode to 300 seconds in
0-200km (0-124 miles) mode to determine the range of the link being installed14. 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 DISARM BOTH
UNITS in the link as described in section 8.3.5. This is necessary for the following:
• Turn off audible alignment aid.
• Enable Adaptive Modulation
• Fully enable Dynamic Frequency Selection
• Clear unwanted installation information from the various systems statistics
• Store the link range for fast link acquisition on link drop
• Enable Higher Data Rates
14 If the unit is operating where mandatory radar avoidance algorithms are implemented the ranging
behavior for the 400 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 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.
63
The units will automatically disarm after 24 hours.
64
8 Web Page Reference
The web user interface has three main sections. The home page presents to the operator a
high level summary of the PTP 400 Series Bridge point-to-point wireless link. The status page
presents a more detailed set of system parameters describing the performance of the
wireless link together with other key system performance metrics. The final section is the
system administrator section. This section is password protected and allows the system
administrator to perform all the day-to-day administrative procedures, e.g. software upgrades
and configuration changes.
The following subsections give a detailed usage guide for all the web user interfaces.
All the web pages are best viewed using a screen resolution of at least 1024 x 768 pixels on a
PC using Microsoft Internet Explorer version 615.
The navigation bar on the left hand side of the web page (Figure 24) is used to move between
the various management pages.
Figure 24 - Menu Navigation Bar
15 The web pages have also been tested with Mozilla Firefox 1.5. Other browsers may function correctly but have not been
tested.
65
The currently selected page is always highlighted with a light blue background. The menu is
hierarchical selecting any menu item which has associated submenu options will
automatically display all sub options.
8.1 Home Page – PTP 400 Series Bridge
The home page for the PTP 400 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
25) normally displays four key system attributes:
Wireless Link Status: The Wireless Link Status attribute as the name suggests 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. 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
administrator to aid the identification of the unit, network or building.
Figure 25 - PTP 400 Series Bridge Home 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 the SNTP (Simple Network Time Protocol) (see section 8.3.13) is enabled a
system clock attribute is displayed giving the date and time of the last page refresh. If SNTP
is disabled then the system clock attribute is not displayed on the home page.
66
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 the 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 home page. Figure 26 shows a
sample alarm screen.
Figure 26 - Alarm Warning Triangle
The following major system alarms are defined:
Install Arm State: The Install Arm State alarm is displayed. This alarm warns when a
wireless unit is in installation mode. After installation the wireless unit should be disarmed.
This will increase the wireless link’s data-carrying capacity and stop the installation tone
generator. The wireless link is disarmed from the ‘Installation Wizard’ see section 8.3.5.
67
Install Status: If any errors are detected during the installation process, the unit will
automatically raise an audible alarm. The install status alarm will be raised with an
appropriate reason code, e.g. the alarm will be raised if an incorrect target MAC address is
specified for the peer PTP 400 Series Bridge wireless unit.
ARQ Is Not Configured: ARQ must be enabled on both ends of the Point-to-Point link. This
error message is generated if there is a mismatch in the ARQ settings between both ends of
the link.
Encryption Is Not Configured On Both Units: Encryption must be enabled on both ends of
the Point-to-Point link before the over-the-air packets can be successfully decrypted. This
error message is generated if encryption is not configured on both units.
Ethernet Link Status: 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 not got an Ethernet cable plugged
into its Ethernet socket.
Master And Slave Have Incompatible Region Codes: The PTP 400 Series Bridge uses
region codes to comply with local regulatory requirements governing the transmission of
wireless signals. Region codes can only be changed by obtaining a new PTP 400 Series
Bridge license key. If this alarm is encountered the appropriate license keys from the country
of operation should be obtained from your distributor. Applying license keys containing the
same region codes to both ends of the link will remove the alarm.
Spectrum Management Channel Warning: The alarm warns a user when the intelligent
spectrum management feature can't find a suitable wireless channel. This alarm occurs when
the signal assessment features of the PTP 400 Series Bridge can’t find a channel to operate
on.
Ethernet Configuration Mismatch: The detection of Ethernet fragments (runt packets) when
the link is in full duplex is an indication of an auto-negotiation or forced configuration
mismatch.
Wireless Link Disabled Warning: Wireless traffic has been disabled via the SNMP
ifAdminStatus attribute.
SNTP No Sync Warning: This warning indicates that SNTP has been enabled but that the
unit is unable to synchronize with the specified SNTP server. Section 8.3.13 explains how to
configure SNTP.
68
8.2 System Status Page
The status page has been designed to give the system administrator a detailed view of the
operation of the PTP 400 Series Bridge from both the wireless and network perspectives.
The page is subdivided into three main categories Equipment, Wireless and Ethernet/Internet.
The ‘Equipment’ section contains the entire unit’s inventory and identification information. The
‘Wireless’ section presents the key wireless metrics displayed as a series of measurements
and histograms. 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 PTP 400 Series Bridge at
this interval.
Figure 27 - Status Page
69
The two PTP 400 Series Bridges 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 the ‘- Slave’ appended to the ‘Systems
Status’ page title.
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 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 FFPP-XX-YY where FF is the frequency variant
(4.9, 5.8 or 5.4 GHz), PP is the product variant, XX is the major release version and YY is the
minor release version.
Hardware Version: The hardware version attribute contains all the combined hardware
version information. The attribute is formatted as DX.-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 the regulatory regime of the particular country. The region code is encoded in the
product license key. If the operator wishes to change the region code, a new license key must
be obtained from Motorola or the local 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
several 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
background indicates that an Ethernet link is established. A state of ‘Down’ with a red
background indicates that the Ethernet link is not established.
Ethernet Speed: The negotiated speed of the Ethernet interface specified in Mbps.
Ethernet Duplex: The negotiated duplex of the Ethernet interface.
70
Full Duplex: 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: 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.
MAC Address: The Medium Access Control Layer (MAC) address is used to uniquely
identify the equipment on an Ethernet network.
IP Address: Internet Protocol (IP) address. This address is used by the family of Internet
protocols to uniquely this identify the unit on a network
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 on the current network that acts as a
gateway. A gateway acts as an entrance / exit to packets from / to other networks.
Wireless Link Status: As the attribute name suggests, this 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. If the link is down for an unknown reason the system administrator should first
consult the status webpage for a more detailed summary of the prevailing system diagnostics.
Target Receive Modulation Mode: The target modulation mode is used by the wireless
subsystem to control the adaptive modulation algorithm. The mode is used by the PTP 400
Series Bridge as an upper limit. The system will not move to a high rate modulation mode
even if the signal / interference environment will support high rate modes.
Maximum Transmit Power: The maximum Transmit Power the local wireless unit is
permitted to use to sustain a link.
Remote Transmit Maximum Power: The maximum transmit power the remote wireless unit
is permitted to use to sustain a link.
71
Transmit Power: Transmit power histogram16 is expressed in dBm and presented as: max,
mean, min, and latest.
Receive Power: Receive power histogram is expressed in dBm and presented as: max,
mean, min, and latest.
Vector Error: The vector error measurement compares the received signal’s In phase /
Quadrature (IQ) modulation characteristics to an ideal signal to determine the composite error
vector magnitude. The results are stored in a histogram and expressed in dB and presented
as: max, mean, min and latest. The expected range for Vector Error would be approximately
0dB (NLOS link operating at sensitivity limit on BPSK ½) to –29dB (short LOS link running
64QAM 7/8).
Link Loss: The link loss is the total attenuation of the wireless signal between the two
point-to-point units.
16 All histograms are calculated over a one hour period. If the equipment has been running for
less than one hour then the histograms are 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 8.3.14
“Diagnostics”.

effective data rate available to all MAC layer protocols.
Transmit Modulation Mode: The modulation mode currently being used on the transmit
channel. The number in brackets after the modulation mode and coding rate string is the
effective data rate available to all MAC layer protocols.
Receive Modulation Mode Detail: The receive modulation mode detail presents to the user
the reason why the wireless link is not operating at the maximum capacity (modulation mode).
Values that can be presented in this field are:
73
• Running at maximum receive mode:
The wireless link is operating at its receive maximum capacity. To confirm that the
wireless link is operating at its maximum transmit capacity either look at the 'Transmit
Modulation Mode' on this page or look at the peer wireless units 'Receive Modulation
Mode Detail' attribute.
• Running at user-configured Target Modulation Mode:
This indicates that the wireless link could operate at a higher capacity but has been
limited in modulation mode by the user from the configuration page.
• Restricted because Installation is armed:
During installation the wireless link is restricted to operate in a low order modulation
mode (BPSK ½ ). Disarming the wireless units after installation will allow the wireless link
to adaptively select its own operational modulation mode.
• Restricted because of byte errors on the wireless link:
During normal operation the wireless link monitors its performance. If byte errors are
detected during normal data transmission / reception the wireless unit automatically
changes the active modulation mode to a more robust mode in order to reduce the
number of errors.
• Restricted because a DFS channel change is in progress:
During Spectrum Management (DFS) channel changes the wireless unit temporarily
reduces the modulation mode to BPSK ½.
• Restricted due to the low Ehthernet link speed:
If the Ethernet link speed is less that the instantaneous wireless link capacity then the
modulation mode is optimized so that the Ethernet link speed is satisfied using the most
robust modulation mode.
• Limited by the wireless conditions:
The wireless link capacity is limited by the current wireless conditions e.g. interference,
excess path loss, etc…

8.3.1 System Configuration Page
The configuration page (Figure 29) is used by the system administrator to configure the PTP
400 Series Bridge.
Figure 29 - 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 link, modulation and physical components.
Link Name: User defined identity for the unit (max 63 characters).
Link Location: Can be used to describe the location of the equipment or any other
equipment related notes (max 63 characters).
Master Slave Mode: 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.
76
Link Mode Optimization: By default, Link Mode Optimization of a point-to-point link is set to
‘IP Traffic’. In this configuration the wireless minimizes packet transmission errors by
automatically adapting the active modulation mode based on instantaneous vector error
measurements and the presence of codeword errors. This mode of operation is
recommended for connection oriented IP traffic protocols where packet loss is perceived by
the protocols as an indication of network congestion. It is recommended that when using this
mode of operation the ARQ state is set to ‘enabled’. The ‘TDM Traffic’ mode is recommended
for E1 / T1 applications and connectionless oriented protocols. In this mode the wireless link
is optimized for minimum transmission latency and preservation of data throughput by
allowing the link to maintain a higher modulation mode in the presence of a limited number of
codeword errors. It is recommended that when operating the link in TDM mode that the ARQ
state is set to disabled and that the Spectrum Management controls are used to fix the
wireless link to a single frequency. This can be achieved by using the installation wizard to
configure single frequency operation. In either case, a system reboot will be required.
Link Symmetry: By default Link Symmetry of a point-to-point link is ‘Symmetrical Data Rate
(1:1)’ in this configuration the ratio of time the wireless link spends transmitting and receiving
is equal. When Link Symmetry is configured to Asymmetric Data Rate (2:1) the wireless link
Master will spend twice as long transmitting as receiving. It should be noted that the data rate
available to the end users might not follow these ratios exactly. The exact data rates will be
dependant on the prevailing modulation modes.
Throughput Optimization: Throughput Optimization has two distinct modes:
• Data Throughput configures the wireless link for maximum data throughput.
• Low Latency configures the wireless link to minimize packet latency during transmission
over the wireless link. When Low Latency mode is selected, the Link Symmetry is
automatically reconfigured to a symmetric link. Link asymmetry is not supported in Low
Latency mode.
Note: The “Throughput Optimization" option is not available on 4.9GHz variants.
ARQ State: Automatic Repeat reQuest (ARQ) is a mechanism where packets lost due to
transmission errors over the wireless link are retransmitted rapidly. The retransmission helps
to prevent TCP congestion mechanisms from inadvertently interpreting intermittent packet
loss as network congestion. ARQ must be enabled on both ends of the point-to-point link for it
to function.
77
Target Receive Modulation Mode: This is the maximum mode the unit will use as its
adaptive modulation. The modulation modes available are:
• BPSK 1 / 2
• QPSK 1 / 2
• QPSK 2 / 3
• 16QAM 1 / 2
• 16QAM 3 / 4
• 64QAM 2 / 3
• 64QAM 3 / 4
• 64QAM 7 / 8
By default the Target Receive Modulation Mode is 64QAM 7/8. The value in brackets shows
the maximum unidirectional data for the current modulation / ranging mode combination.
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 it will be limited to that
country’s regulations.
Ethernet Compression: When Ethernet compression is enabled all compressible Ethernet
packets are transmitted over the wireless link using a compressed data format. This will have
the net effect of increasing wireless link traffic throughput. Because the compression
techniques used in the PTP 400 Series Bridge are CPU intensive, compression is only
applied to modulation modes BPSK 1/2, QPSK 1/2 and QPSK 2/3. The net effect of
compression is solely dependant on the individual packet compressibility (entropy). Random
data will not produce good packet compression; however ASCII text and other non-random
data sources will produce an acceptable level of compressibility.
All 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 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. (See Figure 30)
Figure 30 - Configuration Reboot Page
78
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.
8.3.2 LAN Configuration Page
The LAN Configuration page (Figure 31) is used by the system administrator to configure the
network parameters for the PTP 400 Series Bridge.
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. 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.
79
VLAN High Priority Traffic Threshold: If enabled, this sets the 802.1p VLAN user priority
threshold at which bridged traffic will be treated as high-priority.
Use VLAN for Management Interfaces: If enabled, this allows the use of VLAN for
Management Interfaces. 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. The following
warning message window is displayed when this option is enabled:
Figure 32 - VLAN Warning Window
80
After clicking on OK, the following VLAN options are added to the LAN Configuration window:
Figure 33 - Additional VLAN options
These parameters control 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 communication with the unit is lost due to mis-configuration or the user forgot the VID that
has been set. The unit can be recovered by resetting the unit to factory defaults as described
in Section 3.3.2 “The PIDU Plus – ”.
Note: The internal Ethernet stack used to manage a unit does not support double VLAN
tagged packets. Double VLAN tagged packets will be discarded.
Note: If you loose contact with your unit due to mis-configuration you will need to reset your
unit to factory default as described in Section 3.3.2 “The PIDU Plus – ”
81
Ethernet Configuration: This enables the Ethernet configuration to be forced rather than
auto negotiated. 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 PTP 400 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!
Ethernet Auto Mdix: This enables/disables the Auto Medium Dependent Interface
(MDI)/Medium Dependent Interface Crossover (MDIX) capability.
Drop Ethernet Link On Wireless Link Down: When enabled, this causes the Ethernet link
to be dropped briefly when the Wireless link drops. This is so that spanning tree algorithms
can quickly detect that there is a problem
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 enabled when no external switching/routing hardware is present.
82
8.3.3 Save and Restore Menu
The save and restore feature of a PTP 400 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 400 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 34 and
Figure 35) and save the configuration file (.cfg) to the hard drive of your computer19, 20.
Figure 34 - Save and Restore Configuration Page
19 There is a feature of Internet Explorer (all versions) that will always look at the content of any
downloadable file 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.
20 The configuration file name format is MAC-mm-mm-mm_IP-iii-iii-iii-iii.cfg where mm and iii are the
lower 3 bytes of the MAC address and the unit IP address respectively.

Figure 36 - Example Configuration File
WARNING: 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 replaced 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
Install guide supplied with replacement wireless unit or directly from Motorola. Please note
that the target MAC address at the other end will need to change.
85
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 37). The user will then be prompted to
confirm the action (Figure 38).
Figure 37 - Restore Configuration File Pop Up Screen
86
Figure 38 - Reset Configuration and Reboot Confirmation Pop-up
On confirmation the PTP 400 Series bridge will:
o Upload the configuration file
o Perform data integrity checking
o Erase previous configuration
o Apply the new configuration
o 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 36.
WARNING: A reboot is always required to restore a configuration file.

8.3.5 Install Wizard 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 7.7.10 “Aligning the ODUs”.
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
default configuration data. Table 11 shows a sample link configuration. The values highlighted
have been committed to the wireless units non-volatile storage.
Example PTP 400 Series Bridge Configuration Data

Table 11 - PTP 400 Series Bridge Factory Configuration Values
The factory default configuration is written to the ‘semi-permanent’ configuration bank.
WARNING: 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)
you must follow the ‘Manually Configuring the Wireless Units’ in section 8.3.5.1.
94
8.3.5.1 Manually Configuring the Wireless Units
If the installer / system administrator wishes, they may modify the default installation
configuration. If only the IP addresses are incorrect it is recommended that the values are
changed via the configuration menu (Section 8.3.1). If any other parameters require
modification then it is recommended that the system administrator use the Installation Wizard.
The operational software for the PTP 400 Series Bridge requires a license key to enable the
wireless bridging capability and program region code specific parameters in to the unit.
Please refer to Section 8.3.18 for more information on how to enter and validate a license key
into the unit.
8.3.5.2 Internet Protocol Configuration
Step 1 of the installation wizard requires the installer to enter the Internet Protocol (IP)
configuration.
Figure 41 - Installation Wizard Internet Protocol Configuration.
95
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. 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: This controls whether the management interfaces
(HTTP/SNMP/SMTP/SNTP) use a VLAN. Selecting this option first presents the user with the
warning box shown in Figure 42, then presents the user with extra fields in which to enter the
Management VLAN ID, Priority and whether to validate the VLAN ID, as shown in Figure 43.
Figure 42 - VLAN Warning
96
Figure 43 - Additional VLAN Management Options
Once complete click the ‘Submit Internet Protocol Configuration’ button or the ‘Next’ link.
Note: The internal Ethernet stack used to manage a unit does not support double VLAN
tagged packets. Double VLAN tagged packets will be discarded.
Note: If you loose contact with your unit due to mis-configuration you will need to reset your
unit to factory default as described in Section 3.3.2 “The PIDU Plus – ”
97
8.3.5.3 Wireless Configuration
A discussion of the wireless configuration and its relationship to the band of operations is
contained in section 5 “ General Considerations”. It is recommended that the installer reads
this section before commencing with the product installation.
Step 2 of the installation wizard requires the installer to enter the wireless configuration
parameters:
Figure 44 - Installation Wizard Wireless Configuration
Target MAC Address: 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 400 Series system is shipped as a pair of units with pre-loaded correct MAC
addresses. 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.
98
Master Slave Mode: At this point it is necessary to decide which end will be designated as
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: By default Link Mode Optimization of a point-to-point link is set to
‘IP Traffic’. In this configuration the wireless minimizes packet transmission errors by
automatically adapting the active modulation mode based on instantaneous vector error
measurements and / or the presence of codeword errors. This mode of operation is
recommended for connection oriented IP traffic protocols where packet loss is perceived by
the protocols as an indication of network congestion. It is recommended that when using this
mode of operation that the ARQ state is set to enabled. The ‘TDM Traffic’ mode of link
optimization is recommended for T1 / E1 applications and non-connection oriented protocols.
In this mode the wireless link is optimized for minimum transmission latency and preservation
of data throughput by allowing the link to maintain a higher modulation mode in the presence
of a limited number of codeword errors. It is recommended that when operating the link in
TDM mode that both ARQ state is set to disabled and the Spectrum Management controls
are used to fix the wireless link to a single frequency. This can be achieved by using the
installation wizard to configure single frequency operation (system reboot will be required) or
by using the Spectrum Management channel barring (a system reboot will not be required).
Link Symmetry: By default Link Symmetry of a point-to-point link is ‘Symmetrical Data Rate
(1:1)’ in this configuration the ratio of time the wireless link spends transmitting and receiving
is equal. When Link Symmetry is configured to Asymmetric Data Rate (2:1) the wireless link
Master will spend twice as long transmitting as receiving. It should be noted that the data rate
available to the end users might not follow these ratios exactly. The exact data rates will be
dependant on the prevailing modulation. If the direction you want to install the link asymmetry
is not achievable in the current configuration then the master and slave modes of both PTP
400 Series Bridges will need to be reversed.
Throughput Optimization: Throughput Optimization has two distinct modes:
• Data Throughput configures the wireless link for maximum data throughput.
• Latency Optimized configures the wireless link to minimize packet latency during
transmission over the wireless link.
Note: The Throughput Optimization option is not available on 4.9GHz variants.
99
ARQ State: Automatic Repeat reQuest (ARQ) is a mechanism where packets lost due to
transmission errors over the wireless link are retransmitted rapidly. The retransmission helps
to prevent TCP congestion mechanisms from inadvertently interpreting intermittent pack loss
as network congestion. ARQ must be enabled on both ends of the point-to-point link for it to
function.
Max Transmit 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.
Ranging Mode: During installation the wireless units perform automatic ranging. The ranging
mode allows the installer to control the behavior of the systems automatic ranging algorithms.
The default value is 0 to 40 km22 (0 to 25 miles). If the installer is required to install a link of
greater than 40 km (25 miles) then the ranging mode attribute MUST be configured to ‘0 to
100km’ (0 to 62 miles) or ‘0 to 200km’ (0 to 134 miles) mode depending on the range of the
link. Likewise selecting the 0 to 5 km (0 to 3 miles) mode for links under 5 km (3 miles) will
give you optimal performance.
Target Range: Installers that know the range between the two wireless units to within ± 1 km
(± 0.62 mile) can use the target range mode. The main advantage of the target range mode is
that it reduces the time taken by the units to range. To use the target range mode the installer
MUST select Target Range as the ranging mode and enter the approximate range in km in
the Target range data entry field at both ends of the link.
Spectrum Management Control: Is used to configure the PTP 400 Series Bridge Spectrum
Management features, see section 8.3.8 for more details. I-DFS is the abbreviation for
intelligent Dynamic Frequency Selection. This feature continually monitors the spectrum
looking for a 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.
Lower Center Frequency: The software for the PTP 400 Series Bridge allows a user to
optionally adjust the channel center frequencies. See section 5 “General Considerations” for
further information. This field is only available in i-DFS mode on 5.4 GHz and 5.8 GHz
variants.
22 If preferred 400 Series Bridge range functions can be configured to operate in miles, see the
Properties page in section 8.3.19.
100
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 re-establishment. 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 400
Series Bridge allows a user to optionally fix transmit and receive frequencies for a wireless
link. The settings must be compatible at each end of the link. Once configured the spectrum
management software will not attempt to move the wireless link to a channel with lower co-
channel or adjacent channel interference. Therefore this mode of operation is only
recommended for deployments where the installer has a good understanding of the prevailing
interference environment.
Warning: Ensure that the Rx and Tx frequencies are correct.
Figure 45 shows a sample fixed frequency configuration. See section 5 “ General
Considerations” for further information.
Figure 45 - Fixed Frequency Operation
101
Default Raster: When the Default Raster option is enabled the pull down selection menus
displayed for Fixed Tx Frequency and Fixed Rx Frequency allow the selection of frequencies
available within the default channel raster. When this option is not enabled the pull down
selection menus display all available channel centre frequencies. This option is provided to
ease the selection of fixed channel frequencies.
Fixed Tx Frequency: This field controls the units Transmit frequency.
Fixed Rx Frequency: This field controls the units Receive frequency.
Installation Tones: This option allows the operator to enable of disable the audible
installation tones.
102
8.3.5.4 Confirm Configuration
Step 3 of the installation wizard allows the installer to review and confirm the installation
information before committing the information to non-volatile memory, as shown for different
configuration in Figure 46, Figure 47 and Figure 48.
Figure 46 - Installation Wizard Confirm Configuration
103
Figure 47 - Installation Wizard Confirm Configuration – Fixed Frequency
104
Figure 48 - Installation Wizard Confirm Configuration – Connectorized
105
If all the settings are correct and appropriate click the “Confirm Configuration and Reboot
Unit” button. All the attributes are committed to non-volatile memory. Immediately following
the write to non-volatile memory the unit is reset.
Note: If you have changed the Ethernet parameters you must reconnect using the correct
network and address settings.
If the installer wishes to modify the installation configuration then the ‘Back’ link can be used
to access the installation wizard steps described above.
8.3.5.5 Disarm
The next step of the installation wizard is the Disarm Phase.
Figure 49 - Disarm Installation.
106
Once section 7.7.10 “Aligning the ODUs” is complete pressing the “Disarm Installation Agent”
button completes the installation process23 and the audible installation tone will be switched
off.
After disarming the wireless link the user is presented with an optional configuration page see
Figure 50. The screen presents hyperlinks to the main configuration and spectrum
management pages.
Figure 50 - Optional Post Disarm Configuration 2
Once the installer is satisfied with the wireless configuration options then the ‘Submit Wireless
Configuration’ button or the ‘Next’ link should be clicked.
23 The installation process is completed when both ends of the link are ‘disarmed’.
107
8.3.6 Graphical Install
To aid the installation of wireless links two graphical installation aids have been included:
• 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 51. 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 average size of a PDA screen.

Metric
Figure 51 - Installation Screen
The screen displays the receive power of 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.
108
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.
8.3.7 Software Upgrade
The PTP 400 Series Bridge 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 as and when
necessary.
The ‘Fixed’ image is only used if disaster recovery is required, i.e. if an upgrade process is
interrupted or the units are reset to their factory defaults.
These 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 400 Series Bridge Software image, identifiable
by its ‘.dld’ file extension.
The “Browse” button is used 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 process. The following
figures detail the upgrade process:
109
Figure 52 - Software Upgrade – Step 1
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 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, as shown in Figure 53. If the image is
not correct, the user has the option to go back and reload a new image, as shown in Figure
52.
110
Figure 53 - 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. A progress tracking web page will be presented to the user during the
erasure and programming of non-volatile memory.
WARNING: If the upgrade process is interrupted during the erasure of the image bank or
during the reprogramming of the image bank the image bank will be left in a corrupt state. If
this occurs the software must be reloaded. On power up, if the software image is invalid, for
any reason, the PTP 400 Series bridge will use a known good fixed image. If this occurs the
user must attempt to reload the correct version of software.
Figure 54 - Overall Progress Tracker
111
Once the Overall Update Progress bar has reached 100%, proceed to the next step.
Figure 55 - Software Upgrade Complete
When the software image has been written to memory Figure 55 will be displayed showing
the status of the software upload.
Reboot the unit by clicking the “Reboot Wireless Unit” button. This will reboot the unit within
30 seconds, and during this time you will not be able to communicate with the unit. The unit is
now fully functional.
If this screen is not displayed after 60 seconds it could indicate a problem with the memory
update process.
The user should now power cycle the unit to start using the new software image. The unit’s
boot software will automatically determine the health of the newly uploaded software image. If
any problems were encountered the boot code will revert to a protected fixed software image
After the power cycle the user should check that the required software image is loaded and
running by re-entering the Upgrade page where the software bank status will be displayed.

8.3.8 Spectrum Management
Spectrum Management Selection (also referred to by the acronym DFS) is the PTP 400
Series Bridge wireless 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.
8.3.8.1 Wireless Channels
The PTP 400 Series Bridge operates using a set of predefined channels. Section 5 ”General
Considerations” contains detailed information on this subject with regards each product
variant. It should be noted that some product variants have a channel raster smaller than their
channel size. In these cases the channels overlap and the Spectrum Management displays
should be read accordingly.
The default channelization can be modified by varying the lower center frequency attribute in
the installation wizard – see Section 8.3.5.3 “Wireless Configuration” - Lower Center
Frequency.
8.3.8.2 Spectrum Management Measurements
The PTP 400 Series Bridge performs four Spectrum Management measurements per TDD
cycle, per channel. The measurements are subdivided into two signal peak measurements
and two mean signal measurements. The peak measurements represent the peak received
signal power with a resolution down to 100 ns. The mean measurement represents the mean
received signal power for the 40 μs 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 select 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 channel barring process. Measurements are still collected for all channels
irrespective of the number of barred channels.
8.3.8.3 Measurement Analysis
Spectrum Management uses statistical analysis to process the received peak and mean
measurement. The statistical analysis is based on a fixed, one minute, measurement
quantization period. Spectrum Management collects data for the specified quantization period
and only at the end of the period is the statistical analysis performed.
113
The analysis produces four key metrics for each channel:
• Peak of Peaks
• Peak of Means
• 99.9% Percentile of the Means
• Mean of Means
Peak of Peaks: is the largest peak interference measurement encountered during the
quantization period. This metric is useful for detecting large short duration spikes in the
interference environment.
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 for 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 affect on the mean of means.
Mean of Means: is the arithmetic mean24 of the measured means during a quantization
period. The mean of means is a coarse measure of signal interference and gives an
indication of the average interference level measured during the quantization period. The
metric is not very good at predicting intermittent interference and is included to show the
spread between the mean of means, the 99.9% percentile and the peak of means.
Note: 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.
24 The arithmetic mean is the true power mean and not the mean of the values expressed in dBm.
114
8.3.8.4 The Spectrum Management Master / Slave Relationship
By default 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.
Figure 56 shows a sample Spectrum Management web page as seen from the master.
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.
115
Figure 56 - Spectrum Management - Master
Figure 57 shows a sample PTP 400 Series Spectrum Management web page as seen from
the slave. It should be noted that all the key configuration attributes are not available on the
slave web page.
116
Figure 57 - Spectrum Management – Slave
8.3.8.5 Spectrum Management Configuration
The following section describes the user modifiable configuration accessible from the
Spectrum Management web page. 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.
Refresh Page Period: The page refreshes automatically according to the setting entered
here (in seconds).
Hopping Period: The Spectrum Management algorithm evaluates the metrics every
‘Hopping Period’ seconds (180 seconds by default) looking for a channel with lower levels of
interference. If a better channel is located, Spectrum Management performs an automated
channel hop. If SNMP and or SMTP alerts are enabled an SNMP TRAP and/or an email alert
is sent, warning the system administrator of the channel change.
117
Hopping Margin: Spectrum Management uses this margin when making a channel hop
decision. The channel to hop to has to have an interference level 3 dBs (default) better than
the current active channel. 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.
Hopping Counter: Indicates the number of automatic channel changes that have occurred.
Asymmetric DFS: When disabled this option constrains the link to operate symmetrically
using the same transmit and receive channels. When in symmetric mode the slave unit will
always follow the master. If the master moves to a new channel the slave will hop to the same
channel. When the Point-to-Point link is configured as an asymmetric link both the master and
slave are free to select the best channel from their own set of local interference metrics.
(Default Enabled).
Interference Threshold: Spectrum Management uses the interference threshold to perform
instantaneous channel hops. If the measured interference on a channel exceeds the specified
threshold then Spectrum Management will instruct the wireless to immediately search for a
better channel. If a better channel cannot be found, the PTP 400 Series Bridge will continue
to use the current active channel. (Default –85 dBm)
8.3.8.6 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 conformation dialog. It should be noted that the channel bar will take effect
immediately and is not related to the measurement quantization period.
118
8.3.8.7 Local and Peer Channel Spectrum Graphics
Spectrum Management presents its computed statistical measurements in a graphical display
on both the master and slave DFS web page.
Figure 58 - Sample Spectrum Management Graphic
The X-axis shows a stylized view of the selectable wireless channels. See section 5 “ General
Considerations” for further information. 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 1 in Figure 58) is always marked using hatched green and white
lines. The width of the hatching is directly proportional to the spectral occupancy of the
channel.
The individual channel metrics are displayed using a colored bar, an ‘I’ bar and a peak
symbol. The colored bar represents the following channel state:
Green Active The channel is currently in use hosting the Point-to-Point
wireless link
Orange Interference The channel has interference above the interference
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.
Because the low signal levels encountered when a unit is
powered up in a laboratory environment prior to installation
(which makes the grey of the channel bar difficult to see). An
additional red ‘lock’ symbol is used to indicate that a channel
is barred.
Table 12 - Spectrum Management (Non UK) change state key
The top of the colored bar represents the 99.9% percentile metric for specific channel.
119
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.
The peak symbol (the upper small triangle above each channel ‘I’ bar) is used to indicate the
peak of peaks interference measurement.
8.3.8.8 Active Channel History
The active channel history is a time series display of the channels used by the PTP 400
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 59. 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.
Figure 59 - Active Channel History Screen
120
8.3.8.9 Viewing Historic Spectrum Management Metrics
Spectrum Management allows the system administrator to view the results of previous
measurement 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 webpage.
Figure 60 - Spectrum Management Time series Plot
Figure 60 shows a sample time series plot. A time series plot displays the previous 145
measurement quantization periods. If the PTP 400 Series Bridge has not been running for
145 quantization periods then only the number of measurement quantization periods that are
available are displayed.
RED Peak of Peaks interference measurement
GREEN Peak of Means interference measurement
BLACK 99.9% percentile of means interference measurement
BLUE Mean of Means interference measurement

8.3.8.10 Spectrum Management Online Help
Because the Spectrum Management displays contain a large amount of data, symbols and
color references, an online help screen has been provided see Figure 61. This screen is
accessible from both the master and slave web pages.
121
Figure 61 - Spectrum Management Help Page
122
8.3.9 Spectrum Management - Fixed Frequency
The software for the PTP 400 Series Bridge 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 of the prevailing interference environment. (See
Section 8.3.5.3 “Wireless Configuration” - Fixed Transmit Frequency, Fixed Receive
Frequency). 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 62. 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’.
Figure 62 - Spectrum Management Fixed Frequency Screen- Master
123
Figure 63 - Spectrum Management Fixed Frequency Screen- Slave
Channel barring is disabled in fixed frequency mode; it is not required as dynamic channel
hopping is prohibited in this mode.
The only control available to the master is 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. The active channel history menu is removed in this mode of operation as
channel hopping is prohibited.
8.3.10 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 64 and Figure 65.
• The only controls available to the master are the Interference Threshold attribute. This
has no affect on the operation of the wireless link and will only affect the generation of the
channel spectrum graphics. See Figure 64.
• Extra color coding of the interference histogram is provided. See Table 14.
124
When operating with RTTT Avoidance enabled or other regulatory restrictions on channel
usage the following variances apply:
• A channels marked with a ‘no entry’ symbol with their associated statistics colored black
are the prohibited channels. See Figure 64 and Figure 65. These channels are never
used to host the wireless link, but interference 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.
Figure 64 - Spectrum Management Master Screen with Operational Restrictions
125
Figure 65 - Spectrum Management Slave Screen with Operational Restrictions
The colored bar represents the following channel state:
Green Active The channel is currently in use hosting the Point-to-Point
wireless link
Orange Interference The channel has interference above the interference 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

For a copy of the Motorola proprietary version 1 and version 2 MIB RFCs please consult the
installation CD.
8.3.12.2 SNMP Configuration
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 Trap Version: This determines which SNMP trap version the unit will send: version 1
or version 2c.
128
SNMP Community String: The SNMP community string acts like a password between the
networks SNMP management entity and the distributed SNMP clients (PTP 400 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: The SNMP port number used by the agent for all GET, SET, WALK
PDUs.
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.
8.3.12.3 SMTP (Simple Mail Transport Protocol)
The SMTP client is an alternative method for the PTP 400 Series Bridge to alert the outside
world 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 PTP 400 Series Bridge 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 PTP 400 Series Bridge
will send the alert messages.
129
8.3.13 SNTP (Simple Network Time Protocol)
The SNTP client allows the PTP 400 Series Bridge to obtain accurate date and time updates
from a networked timeserver. The resultant time information is used by the SNMP, web page
and System Reboot tasks.
SNTP State: The SNTP state attribute controls the creation of the SNTP features.
When enabled the following options are available:
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.
SNTP Sync: Displays whether the SNTP client is in sync with the specified SNTP
server.
SNTP Last Sync: The timestamp of the last time the SNTP client successfully
synchronized with the SNTP server.
System Clock: Displays the current system clock.
SNTP Time Zone: The SNTP time zone is a fixed offset from GMT that is added to
the correct time to allow the expression of time in all geographic time zones.
When disabled the following options are available:
Set Time: Field used to set the current time (HH:MM:SS).
Set Date: Pull down menus to set the current date.
Time Zone: The time zone is a fixed offset from GMT that is added to the correct
time to allow the expression of time in all geographic time zones.
Daylight Saving: Enables daylight saving by adding one hour to the displayed system clock
timestamp.
130
8.3.14 Diagnostics
Link performance data is stored as a set of cascaded histograms:
• Histogram 1: the last hour at a resolution of 1 second
• Histogram 2: the last day (24 hours) at a resolution of 1 minute
• Histogram 3: the last month (30 days) at a resolution of 1 hour
The histograms are linked together by cascading data from one to the next: As a histogram
fills up, the data overflow is used as input to the next histogram in the chain.
For example, raw data is collected at a 1 second resolution and stored in Histogram 1.
Once Histogram 1 fills up, every minute the oldest minute of data (i.e. the 60 oldest seconds)
are analyzed and removed from the histogram (to make room for new data). The maximum,
minimum and mean values are computed and inserted as the next data set in Histogram 2.
Once Histogram 2 fills up, every hour the oldest hour of data (i.e. the 60 oldest minutes) are
analyzed and removed from the histogram (to make room for new data). The maximum,
minimum and mean values are computed and inserted as the next data set in Histogram 3.
Once Histogram 3 fills up, every hour the oldest hour of data is discarded.
131
8.3.15 Diagnostics Plotter
The system has the diagnostics plotter facility shown in Figure 67.
Figure 67 - 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
available histograms are:
• Vector Error
• Rx Power
• Tx Power
• Signal Strength Ratio V/H
• Link Loss
• Rx Data Rate
• Tx Data Rate
• Aggregate Data Rate
• Receive SNR
• Rx Gain
132
The diagnostic plotter displays all of the data from the cascaded Histograms 1, 2 and 3. It
uses a bespoke x-axis with a compressed timeline so that resolution is not sacrificed. The
most recent data is shown to the right, and the oldest data to the left.
The most recent hour's worth of data from Histogram 1 is displayed between 0 minutes (0m)
and 60 minutes (60m) to the right of the x-axis; Data for the previous 24 hours from
Histogram 2 is displayed between 60 minutes (60m) and 25 hours (25h) in the middle of the
x-axis; Data for the previous 30 days from Histogram 3 is displayed between 25 hours (25h)
and 31 days (31d) to the left of the x-axis.
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.
8.3.16 Diagnostic Download
The diagnostics Download page allows the system administrator to download snapshots of
system diagnostics.
Figure 68 - CSV Download
The following diagnostics are available:
• Vector Error
• Rx Power
• Tx Power
• Signal Strength Ratio V/H
• Link Loss
• Rx Data Rate
• Tx Data Rate
• Aggregate Data Rate
• Receive SNR

days.
134
8.3.18 License Key
The License Key data entry page allows the system administrator to update the PTP 400
Series Bridge license key. Figure 70 shows a sample license key data entry page.
Figure 70 - Software License Key Data Entry
The user must enter the license key and click the ‘Validate License Key’ button to check that
the key is valid and store it in non-volatile memory.
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 Start Guide. If
subsequently the license key has been mislaid, replacement keys can be applied for online.
If a valid license key is not detected in the unit’s non-volatile memory, the user is prompted to
enter a valid key. It should be noted that PTP 400 Series Bridge are shipped as link pairs and
as such, valid license keys are entered during the production process. Hence the user should
never see the Software License Key screen (Figure 70).
To enter a license key simply type or paste the license key into the data entry box and click
the ‘validate license key’ button.
135
If a valid license key is detected, the user will be presented with a message to say that the
key is valid and that the system needs rebooting, as shown in Figure 71.
Figure 71 - License Key Reboot Screen
8.3.19 Properties

8.3.20 Reboot
The reboot page allows the system administrator to perform commanded reboots of the
wireless unit. The reboot page also allows the system administrator to view a list of past
reboot reasons. The reasons for the reboot field has been implemented as a drop down
selection box, where the latest reason for reboot is located at the top of the list.
If the SNTP service from the remote management section above is active then the command
reboot commands will be accompanied by the date and time the reboot was requested.

9 Fault Finding
If communication has been lost with the unit at the near end of the link, 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.
9.1 Hardware
If there are problems suspected with the link hardware the following procedure is
recommended. The following diagram illustrates the main system connections.
Figure 74 - Main System Connections
9.1.1 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 then26 check the Ethernet
LED. If neither is illuminated then there is no voltage on the power wires to the ODU.
1. Check that the mains power is connected and switched on.
2. Check that the lamp illuminates if the ODU connector is disconnected at the PTP 400
Series Bridge PIDU Plus. (Remove the PIDU Plus cover).
a. If it does illuminate then either the ODU is drawing too much current, or the power
wiring to the ODU is short circuited or the PSU is supplying insufficient power. The
likely fault can be determined by removing the jumper (J905), 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.
26 The power indicator LED should be continually illuminated.
138
b. 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 circuited by measuring the
impedance across the Power connector. Is the lamp faulty?
9.1.2 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.
Differentiating between 1--3 and 4 can be achieved by cycling the mains power. Watch the
Ethernet indicator for 1 minute, 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 through to running normally.
If the Ethernet indicator flashes initially but then stops flashing, the ODU is powered and
software loaded but Ethernet connectivity has been lost between the ODU and the users

9.2 Radio
9.2.1 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 mis-configured at each end of the link.
• Check Range
• Check Tx Power
• Check License key
• Check Master Slave
• Check that the link has not been further obscured or the ODU misaligned.
• Check the Spectrum Management 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.
9.2.2 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 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
• Check that one or both ends of the link are not in installation mode (ARMED)

11 Lightning Protection
EMD (Lightning) damage is not covered under 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 not implied or 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
and by reducing the electromagnetic field.
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 un-attenuated
electromagnetic field is still present.
The zones are determined using the ‘rolling sphere method’, an imaginary sphere, typically 50
meters (164 feet) 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 76 and Figure 77) show this zoning pictorially:
143
Equipment mounted in Zone A should be capable of carrying the full lightning current.
Mounting of the ODU in Zone A is not recommended, and should only be carried out
observing the rules governing installations in Zone A28 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 8 AWG.
This grounding wire should be connected to a grounding rod or the building grounding system
before entry in to building.
The ODU grounding point for the PTP 400 Series Bridge can be found on the bottom of the
unit, and is supplied with an appropriate grounding lug for attachment to the ODU.
11.2 Detailed Installation
The recommended components for an installation protected for nearby strikes are:
• Grounding Kits — Andrew Type 223158 (HTUwww.andrew.comUTH)
• Screened CAT 5e Cable also known as Shielded CAT 5e or CAT 5e STP (Shielded
Twisted Pair)
• Surge Arrestor: Transtector Type ALPU-ORT - 4 per link (www.transtector.com)
• Grounding Stake
• RJ45 screened connectors
• 8 AWG Grounding Cable – Minimum size, preferably 6 or 4
• NB: 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)
28 Local regulations may also require the fitting of the 8 AWG ground wire referred below.

147
Figure 80 - Lower Grounding Configuration
The Andrew Grounding Kit at the ODU is optional providing a Surge Arrestor Unit is located at
the ODU and is reliably grounded. However, it may be a regulatory requirement to cross-
bond the screened CAT-5 at regular intervals up the mast. Refer to local regulatory
requirements for further details.
148
The PTP 400 Series Bridge PIDU Plus to ODU cable requires Surge Arrestor Units mounted
at both ends of the cable. At the ODU, the Surge Arrestor Unit should be mounted within
0.3m (1 foot) of the ODU and must be grounded to the ODU. For mast installations, the Surge
Arrestor Unit should be mounted at the same height as the ODU.
The lower Surge Arrestor Unit should be mounted at the building entry point and must be
grounded.
The termination of the CAT-5 Cable into the Surge Arrestor Unit is illustrated in Table 16,
Table 17 and Figure 81. The screen from the cable must be terminated into the ground
terminal within the unit to ensure the continuity of the screen. Earth Sleeving should be used
to cover the shield ground connection to prevent internal shorting within the unit.

11.3.2 Post-Power Testing
1 Connect the RJ45 to the PIDU and apply power. The power LED should be illuminated
continuously. If the power LED does not illuminate unplug 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.
2 The Ethernet LED should be observed starting with 10 slow flashes, 30 seconds after
powering. This confirms that the ODU has the correct power connections, if the Ethernet
LED does not light check the wiring to pins 4 & 5 and 7 & 8.
3 If a computer, switch or router is connected to the LAN side of the PIDU Plus then the
Ethernet LED should flash with network activity. If the Ethernet LED does not show
Ethernet activity then the network equipment and the Ethernet cables need to be
checked, specifically continuity through to the ODU of pins 1 & 2 and 3 & 6.
153
12 Wind Loading
12.1 General
Antennas and electronic equipment mounted on towers or pole mounted on buildings will
subject the mounting structure to 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 PTP 400 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 PTP 400 Series Bridge Unit at different wind speeds is
shown below:

154
Note: When the connectorized version of PTP 400 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 400 Series Bridges
The structure and mounting brackets of PTP 400 Series Bridge systems are capable of
withstanding wind speeds up to 150mph (242kph). The installer should ensure that the
structure to which the PTP 400 Series Bridge is fixed to is also capable of withstanding the
prevalent wind speeds and loads.
12.4 Wind Speed Statistics
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:
• USA Reported Fastest Single Wind Velocities for Selected U.S. Cities (Source: National
Weather Service)

13 PTP 400 Series Bridge - Connectorized version of the PTP 400
Series bridge
13.1 Scope
This section details the changes and additional features relevant to the Connectorized version
of the PTP 400 Series bridge.
13.2 Product Description
13.2.1 Hardware
The Connectorized version of the PTP 400 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 400 Series Integrated product. 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 83 - Connectorized version of the PTP 400 Series bridge Outdoor Unit
Note: Connectorized version of the PTP 400 Series bridge are supplied without Antennas
156
13.2.2 Antenna Choices – 4.9 GHz
The integrated antenna has a gain of 22dBi.
In FCC/Industry Canada regions when using antennas with >26 dBi of gain it is necessary to
turn down the TX Power by the number of dB that 26 dBi has been exceeded.
13.2.3 Antenna Choices – 5.8 GHz
The integrated antenna has a gain of 23.5 dBi.
In non-FCC regions antenna choice is not restricted but any region specific EIRP limit should
be obeyed, see Table 7 in section 5.2 “Region Codes”
In FCC regions external antennas from the list in Section 13.7 “Antennas for 5.8GHz FCC
Regions” can be used with the Connectorized version of the PTP 400 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 28dBi per antenna.
• Single/Dual Polarization Parabolic Dish Antennas – up to 37.7dBi per polarization or
antenna.
In FCC regions when using external antennas – cable loss between the Connectorized
version of the PTP 400 Series bridge and the antenna ports must not be less than 1.2dB
13.3 Software/Features
The variant operates in the same way as the basic PTP 400 Series Bridge product and is
released initially with the feature set of the Connectorized version of the PTP 400 Series
bridge. The areas where the functionality is modified are:
157
13.3.1 Status Page
Figure 84 - Connectorized version of the PTP 400 Series bridge Status Page
The link loss calculation presented on the Status Page on 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 version of the PTP 400 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-2-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.
158

Note: The default Antenna gain for the 4.9 GHz variant is 22 dBi.
Cable Loss: in the cable between the ODU and the antenna. Note: In the event that there is
a significant difference in length of the antenna cables for the two antenna ports, then the
average value should be entered.

13.3.3 Installation Pages
The installer is prompted to enter the Antenna Gain and Cable Loss (Connectorized version
of the PTP 400 Series bridge to antenna) at each end of the link. The Installation Page(s) is
shown as Figure 86 to Figure 88.

13.4 Deployment Considerations
The majority of radio links can be successfully deployed with the PTP 400 Series Bridge. It
should only be necessary to use external antennas where the Link Budget Calculator
indicates marginal performance for a specific link – for example, when the link is heavily
obscured by dense woodland on an NLOS link or extremely long LOS links (>80km or > 50
miles) over water.
The external antennas can be either dual-polarization (as the integrated antenna) or two
single polarized antennas can be used in a spatially diverse configuration. It is expected that
the dual-polarization antennas would normally be used to simplify the installation process;
spatially diverse antennas may provide additional fade margin on very long LOS links where
there is evidence of correlation of the fading characteristics on Vertical and Horizontal
polarizations.
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
link estimation tools. For more information see the Motorola web site.
13.6 Regulatory Issues
In countries where FCC regulations are not relevant, installations should 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 7 in section 5.2 “Region Codes” for any EIRP restrictions that may apply in your
region.
13.6.1 Antenna Choice (5.8GHz FCC Regions Only)
The antennas which can be deployed with the Connectorized version of the PTP 400 Series
bridge are shown in Table 20.
163
13.6.2 Cable Losses (5.8 GHz FCC Regions Only)
The FCC approval for the product is based on tests with a cable loss between the units of
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).

13.8 Installation
This section covers the generic installation instructions for the bridge point-to-point wireless
Ethernet bridges. The actual installation procedure will depend on antenna choice, cable
choice, required antenna separation etc.
13.8.1 Antenna Choice
There are a wide variety of antennas that can be used with the Connectorized version of the
PTP 400 Series bridges. The main selection criteria will be the required antenna gain. The
secondary criteria should be the ease of mounting and alignment.
166
13.8.2 Cables and Connectors
Cables should be selected using the above criteria. However is 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 an adhesive lined heat shrink sleeve that is fitted over the cable/connector
interface.
The connectors required at the Connectorized version of the PTP 400 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.
13.8.3 Tools
The tools required for mounting an Connectorized version of the PTP 400 Series Bridge are
the same as those required for an Integrated PTP 400 Series Bridge unit detailed in section
7.3 “Tools Required”. The tools required for mounting the antennas are specific to the
antenna chosen. The installer should refer to the antenna manufacturer’s instructions.
13.8.4 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
13.8.5 Mounting
13.8.5.1 Connectorized version of the PTP 400 Series bridge
A Connectorized version of the PTP 400 Series Bridge ODU is shipped with the same bracket
as is supplied with an Integrated ODU. Details on the use of this bracket can be found in
section 3.3.7 “Mounting Brackets”. The ODU 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.
167
When using dual polar antennas the ODU 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 13.7 ”Antennas for 5.8GHz FCC
Regions”).
When using separate antennas the ODU should be mounted in such a position as to minimize
both cable runs between the ODU and the antennas. It is not necessary to mount the ODU at
the mid point between the antennas.
13.8.6 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 (66 feet) apart or at a certain distance from the
ground to get the desired results.
13.8.7 Alignment Process
When aligning antennas deployed with a Connectorized version of the PTP 400 Series
Bridge, it may not be possible to hear the alignment tone emanating from the ODU. In this
case it may be necessary for a second installer to assist in the operation. Alternately 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.
13.8.8 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 7.7.10 ”Aligning the PTP 400
Series ODUs”.
13.8.9 Separate Antennas
When using separate antennas to achieve special diversity it is recommended that one 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 ODU
168
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 ODU
Step 6: Connect the 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 7.7.10
“Aligning the PTP 400 Series ODUs”.
Step 8: Connect the other antenna to the ODU.
Step 9: Disconnect the cable to the already aligned antenna.
Step 10: Align the second antenna using the tones as described in section 7.7.10 “Aligning
the PTP 400 Series ODUs”.
Step 11: Re-connect the second antenna to the ODU (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.
13.8.10 Completing the Installation
The installation should be completed by checking all mounting nuts bolts and screws,
securing all cables and weatherproofing the installation.
WARNING: Final tightening of the antenna mountings may cause the antenna alignment to
be altered due to distortion in the mounting bracket caused by tightening. It is recommended
that the installation tone be left turned on (armed) during this process so that any movement
can be noticed and counter acted by tightening the other side of the bracket.
13.8.11 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 version
of the PTP 400 Series Bridge unit 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.
169
13.8.12 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.
Drip loop
Antenna
Figure 89 - Forming a Drip Loop
All joints should be weatherproofed using self-amalgamating tape. It is recommended that a
layer of PVC tape be placed over the self-amalgamating tape to protect the joint while the
self-amalgamating tape cures and give additional protection. Figure 90 shows this
diagrammatically for the Connectorized version of the PTP 400 Series bridge unit 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 cables.

13.9 Additional Lightning Protection
The following guidelines should be applied in addition to those described in Section 11
”Lightning Protection”.
13.9.1 ODU Mounted Outdoors
Where the ODU is mounted outdoors and is mounted some distance from the antenna it is
advisable to add additional grounding by utilizing Andrew Assemblies (such as Andrew Type
223158 www.andrew.com) as shown in Figure 91.

14 Wireless Link Encryption
The PTP 400 Series Bridge system supports link encryption using the NIST approved
Advanced Encryption Standard, FIPS-197. 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 400 Series Bridge. A license key to
enable link encryption can be purchased from your Motorola Point-to-Point Solutions Provider
or Distributor. AES can be activated on receipt of the activation on the Motorola License Key
Generator page.
14.1 Configuring Link Encryption
After purchasing AES encryption for the PTP 400 Series Bridge, 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 400 Series Bridge wireless link.
14.1.1 License Keys
The first step when configuring link encryption is to enter the new license keys in both PTP
400 Series Bridge wireless units.
Figure 94 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 400 Series Bridge system
administration pages, please contact your designated system administrator.
It must be noted that configuring link encryption will necessitate a PTP 400 Series Bridge
service outage. Therefore it is recommended that the configuration process is scheduled
during an appropriate period of low link utilization.
174
Figure 94 - Software License Key Data Entry
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)
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.
175
14.1.2 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 95 be used to configure AES link encryption.
Figure 95 - 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 ‘AES (Rijndael)’ Encryption Algorithm.
4. At both ends of the link enter a 128-bit encryption key. Note the key consists of 32 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.
5. Submit configuration on both ends of the link, but do not reboot.
176
6. Reboot both ends of the link Figure 96. 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 96 - Configuration Reboot Screen
14.2 Wireless Link Encryption FAQ
14.2.1 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.
14.2.2 Link fails to bridge packets after enabling link encryption
If the wireless link status on the status web page indicates that the link is UP, 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.

No. The PTP 400 Series Bridge uses a non-standard PoE configuration. Failure to use the
Motorola supplied Power Indoor Unit (PIDU Plus – PTP 400 Series) could result in equipment
damage and will invalidate the safety certification and may cause a safety hazard.
Q: Who is Motorola?
Motorola, Inc. is a specialist wireless manufacturer with a high quality engineering team that
is developing advanced radio solutions that allows high capacity building-to-building bridges
to be established even in deep non-Line-of-Sight conditions.
Q: Why has Motorola launched the PTP 400 Series Bridge?
The PTP 400 Series Bridge is the first product in this band to feature Multiple-Input Multiple-
Output (MIMO). The PTP 400 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.
Q: What is Multiple-Input Multiple-Output (MIMO)?
The PTP 400 Series Bridge radiates multiple beams from the antenna - which significantly
protects against fading and radically increases 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.
Q: What do you mean by “non-Line-of-sight”?
This term refers to a wireless connection between two points without optical line-of-sight. i.e.
with obstructions in between the antennas but the transmitted signal is still able to reach the
receiver and produce a good quality link.
187
Q: What else is special about the PTP 400 Series Bridge?
There are many special features built-in to the hardware of the PTP 400 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 PTP 400 Series Bridge has a built-
in web server for advanced management capabilities including detailed radio signal
diagnosis.
Q: In which frequency band does the PTP 400 Series Bridge operate?
The Motorola point-to-point PTP 400 Series Bridges operate in the 4.9 GHz USA National
Public Safety Band, the unlicensed 5.4 GHz (ETSI Band B) and 5.8 GHz (ETSI Band C and
FCC ISM band).
Q: Why does the PTP 400 Series Bridge operate in the 5 GHz 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.
Q: Is the PTP 400 Series Bridge an 802.11a device?
No. Although similar, the PTP 400 Series Bridge uses different encoding and radio
transmission systems than 802.11a. In areas where 802.11a systems are operating, the PTP
400 Series Bridge will detect the 802.11a radio signals and choose a clean channel away
from any interference.
Q: How much power does the PTP 400 Series Bridge transmit?
At all times the PTP 400 Series Bridge operates within country / region specific regulations for
radio power emissions. In addition, the PTP 400 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.
Q: How does the PTP 400 Series Bridge avoid interference from other devices nearby?
At initialization, the PTP 400 Series Bridge monitors the available frequency channels to find
a channel that is clean from interference. In operation, the PTP 400 Series Bridge
continuously monitors the spectrum to ensure it is operating on the cleanest channel.
188
Q: How does the PTP 400 Series Bridge integrate into my data network?
The PTP 400 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 PTP 400 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.
Q: How does the PTP 400 Series Bridge provide security for data traffic?
The PTP 400 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. If further security is required the user is
now able to optionally augment the existing high security by encoding the air interface using
AES.
Q: How is the Advanced Encryption Standard (AES) enabled?
The AES facility is enabled by the user obtaining a license key from Motorola. Entering the
key will turn on the AES option from which the user will be able to turn on AES. The default
setting for AES is off.
Q: How do I manage the PTP 400 Series Bridge?
The PTP 400 Series Bridge has a built-in web server. At installation, the unit is configured
with an IP address so that the web server can then be accessed from any browser equipped
terminal. For security, access can be password protected, meaning only the network
administrator can access the web based management tools. SNMP V2c is also available and
the unit can be configured to send traps or email notifications via SMTP.
Q: Can I use Apple Macintosh OS X to control and monitor my PTP 400 Series Bridge?
Yes, but there are some restrictions. Mozilla 1.6 is recommended. There are some issues
with Internet Explorer 5.2(IE) and Safari, which could mislead the user.
189
Q: How will my investment be protected as new features are developed?
Future enhancements can be downloaded to the unit, meaning advances in technology or
changes in regulations can quickly be applied to the system without any further hardware
investment.
Q: Why can’t I change the channel raster centre frequencies on a PTP 49400?
The PTP 49400 provides full band coverage without moving the channel raster. Therefore this
option is not provided.
Q: Why does the PTP 49400 not have a Latency vs. Throughput option?
Due to the narrow channel Low Latency Mode and Throughput mode have the same latency
and throughput. Therefore this option is not provided.
Q: Why is the PTP 49400 Maximum TX power 23 dBm rather than 25 dBm?
The maximum TX power is restricted to 23 dBm due to Type Approval power restrictions.
