Compliance
General
Changes or modifications not expressly approved by Motorola could void the user’s authority to
operate the system.
NOTE: This system has achieved Type Approval in various countries around the world. This means
that the system has been tested against various local technical regulations and found to comply. The
frequency bands in which the system operates may be ‘unlicensed’ and, in these bands, the system
can be used provided it does not cause interference. Further, it is not guaranteed protection against
interference from other products and installations.
The system has been tested for compliance to both US (FCC) and European (ETSI) specifications. It
has been shown to comply with the limits for emitted spurious radiation for a Class B digital device 1,
pursuant to Part 15 of the FCC Rules in the USA and appropriate European ENs. These limits have
been designed to provide reasonable protection against harmful interference. However the equipment
can radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to other radio communications. There is no guarantee that
interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
•
Reorient or relocate the Outdoor Unit (ODU).
•
Increase the separation between the affected equipment and ODU.
•
Connect the ODU/PIDU into a power outlet on a circuit different from that to which the
receiver is connected.
•
Consult your installer or supplier for help.
Deployment and Operation
The Radio Regulations of various countries’ limits constrain the operation of radio products 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 600 Series Bridge is controlled by the use of Region-specific
License Keys.
The following examples show how the regulatory limits apply in some specific countries at the current
time. Operators should note that regulations are subject to change.
Contact your supplier/installer to ensure that your product is set for the correct License Key for your
Country/Region and to ensure that you have fulfilled all the local regulatory requirements, especially if
you are intending to use a link with external antennas. Footnotes to the table below indicate countries
where registration of the link is currently mandatory.
Class B Digital Device, A digital device that is marketed for use in a residential environment, notwithstanding use in
commercial, business and industrial environments.

2 Avoiding Hazards
2.1
Preventing Overexposure to RF Energy
WARNING: To protect from overexposure to RF energy, install the radios for the 600 family
of PTP wireless solutions so as to provide and maintain the minimum separation distances
from all persons as shown in Table 3.
When the system is operational, avoid standing directly in front of the antenna. Strong RF
fields are present when the transmitter is on. The Outdoor Unit (ODU) must not be deployed
in a location where it is possible for people to stand or walk inadvertently in front of the
antenna.
At these and greater separation distances, the power density from the RF field is below
generally accepted limits for the general population.
NOTE: These are conservative distances that include compliance margins.
2.1.1
Calculations for Separation Distances and Power Compliance Margins
Limits and guidelines for RF exposure come from:
•
US FCC limits for the general population. See the FCC web site at http://www.fcc.gov,
and the policies, guidelines, and requirements in Part 1 of Title 47 of the Code of Federal
Regulations, as well as the guidelines and suggestions for evaluating compliance in FCC
OET Bulletin 65.
•
Health Canada limits for the general population. See the Health Canada web site at
http://www.hc-sc.gc.ca/ewh-semt/pubs/radiation/99ehd-dhm237/limits-limites_e.html and
Safety Code 6.
•
EN 50383:2002 Basic standard for the calculation and measurement of electromagnetic
field strength and SAR related to human exposure from radio base stations and fixed
terminal stations for wireless telecommunication systems (110 MHz - 40 GHz).
•
ICNIRP (International Commission on Non-Ionizing Radiation Protection) guidelines for
the general public. See the ICNIRP web site at http://www.icnirp.de/ and Guidelines for
Limiting Exposure to Time-Varying Electric, Magnetic, and Electromagnetic Fields.
The applicable power density exposure limits from the documents referenced above are:
•
6 W/m2 for RF energy in the 900-MHz frequency band in the US and Canada.
•
10 W/m2 for RF energy in the 2.4-, 5.2-, 5.4-, 5.8- and 5.9 GHz frequency bands.

Notes:
•
The regulations require that the power used for the calculations is the maximum power in
the transmit burst subject to allowance for source-based time-averaging.
•
At 5.4GHz the product is generally to a fixed EIRP which can be achieved with the
Integrated Antenna. If there are no EIRP limits, use the distance calculations for 5.8GHz.
•
At 5.8GHz, for antennas between 0.6m (2ft) and 1.8m (6ft), alter the distance
proportionally to the antenna gain.
•
At 2.5 GHz, for antennas between 1.2m (4ft) and 3.6m (12ft) the safe distance is
increased to between 0.8m (2.6 ft) and 2.4m (7.8 ft).

Product Description
This User Manual is specifically written for the 600 family of point-to-point broadband wireless
solutions. The PTP 600 Series Bridge has been developed to provide Point-to-Point data
connectivity via a 2.5 GHz, 4.5 GHz, 4.9 GHz, 5.4 GHz, 5.8 GHz or 5.9 GHz wireless
Ethernet bridge operating at broadband data rates. The PTP 600 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 600 Series Bridge Deployment
The PTP 600 Series Bridge offers true non-line-of-sight (NLOS) operation by using a
combination of Orthogonal Frequency Division Multiplexing (OFDM) modulation and MultipleInput Multiple-Output (MIMO) techniques. These technologies enable the PTP 600 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 600 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.
35
3 Getting Started
Each end of the link consists of:
•
An integrated (or connectorized -see section 13) outdoor transceiver unit containing all
the radio and networking electronics hereafter referred to as the Outdoor Unit (ODU).
•
An indoor connection box containing a mains power supply, status indicators and network
connection port. Hereafter referred to as the Power Indoor Unit Plus (PIDU Plus).
A pair of units is normally supplied pre-configured as a link.
The network connection to a PTP 600 Series Bridge is made via a 1000BaseT Ethernet
connection. Power is provided to the ODU over the 1000BaseT Ethernet connection using a
patented non-standard powering technique.
Previous releases of the PTP 600 Series Bridge platform used different powering and
connection arrangements. Users of equipment prior to “Mod Record 1” should refer to the
User Guide shipped with the original equipment. The “Mod Record” label can be found on the
back of the ODU as shown in Figure 2.
Figure 2 - Mod Record Label
Alternatively, the network connection to a PTP 600 Series Bridge can be made using a
1000BaseSX Fiber Optic cable connected directly to the ODU. In this case power is still
provided over the 1000BaseT Ethernet connection. In the case of Fiber Optic cable failure the
PTP 600 Series Bridge will automatically fall back to the copper Ethernet connection
(provided the cable length <=100m [330 ft]). “PTP 600 Series Optical Interface Upgrade Kits”
can be obtained from your distributor, reseller or system integrator.
Power is fed into the PTP 600 Series Bridge PIDU Plus from the mains via a standard “figure
of eight” mains plug. Connection between the ODU and PIDU Plus is made using standard
CAT5e outdoor UV resistant cable. Connection between the PIDU Plus and the Network
Equipment is made using standard CAT5e cable.
36
3 Getting Started
3.3.1
The Outdoor Unit (ODU)
The ODU is a self-contained unit. It houses both radio and networking electronics. The ODU
for the PTP 600 Series Bridge should only be deployed using the supplied PTP 600 Series
Bridge PIDU Plus. Figure 3 shows an installation example of a PTP 600 Series ODU with a
Motorola lightning protection unit (PTP-LPU).
Figure 3 – PTP 600 Series Bridge Outdoor Unit (ODU) with PTP-LPU
37
3 Getting Started
3.3.2
PIDU Plus – PTP 600 Series Bridge
The PTP 600 Series Bridge PIDU Plus is used to generate the ODU supply voltage from the
mains supply and inject this supply voltage into the 1000BaseT Ethernet connection to the
ODU. Connection uses a CAT5e cable using standard RJ45 wiring.
CAUTION Care should be taken not to connect equipment other than an ODU for the PTP
600 Series Bridge to a PIDU Plus ODU port as equipment damage may occur. The PTP 600
Series Bridge PIDU Plus is not interchangeable with the PTP 400 Series PIDU Plus.
Figure 4 - Power Indoor Unit (PIDU Plus) – PTP 300/500/600 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 8 “Fault Finding” for further fault finding information.
At the bottom of the PIDU Plus is an entry point for the PIDU Plus to ODU cable, the
1000BaseT Ethernet network port and the Recovery switch.
Figure 5 – PIDU Plus Recovery Switch Location
38
3 Getting Started
The Recovery switch is used to recover the unit from configuration errors or software image
corruption. To put a PTP 600 Series Bridge into Recovery mode the Recovery switch should
be pressed then the power applied. The Recovery switch should be kept pressed for at least
20 seconds after the power has been applied. Full instruction on the recovery mode can be
found in Section 9 “Recovery Mode”.
A simple reboot can be performed by removing and re-applying the mains power to the PTP
600 Series Bridge PIDU Plus.
On the left hand side of the PIDU Plus, 48V DC input and output connections can be found.
These are used to power the PTP 600 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
Alternative Powering Configurations”.
WARNING When using alternative DC supplies the supply MUST comply with the following
requirements:
•
The voltage and polarity is correct and is applied to the correct terminals in the PIDU Plus
•
The power source is rated as SELV
•
The power source is rated to supply at least 1A continuously
•
The power source cannot provide more than the Energy Hazard Limit as defined by
IEC/EN/UL6090, Clause 2.5, Limited Power (The Energy Hazard Limit is 240VA)
Also on the left hand side of the PTP 600 Series Bridge PIDU Plus, connectors and jumpers
can be found that allow the remote connection of power LED, Ethernet LED and Recovery
switch. The connection instructions can be found in Section 3.3.4 “Remote LEDs and
Recovery Switch”.
The input supply range for the 600 Series PIDU Plus is 90V-264V AC, 47-63Hz. Mains
connection to the PIDU Plus is made using a standard “figure of eight” mains lead as shown
in Figure 6.

Redundancy and Alternative Powering Configurations
NOTE: The use of DC supplies of less than 55v will reduce the usable distance between the
PIDU Plus and ODU see Figure 7.
Figure 7 – PTP 600 Series Bridge PIDU Plus to ODU Cable Length Graph
CAUTION: The maximum distance from the ODU to the connected network equipment is
100m (330 ft) when using 1000BaseT. Powering distances over 100m (330 ft) are only
applicable when using a 1000BaseSX (Fiber Optic) connection.

Remote LEDs and Recovery Switch
The PTP 600 Series Bridge PIDU Plus provides a facility to connect remote LEDs and
Recovery switch allowing the PIDU Plus to be mounted inside an enclosure. At the left hand
end of the PIDU Plus under the ODU connection cover can be found a PCB header and three
jumpers. Jumpers J906 and J907 should be removed and connection to the remote LEDs and
Recovery switch made to J908 as shown in Figure 11.
Figure 11 - Remote LED and Recovery Switch Wiring
3.3.5
Cables and connectors
The cable used to connect the PTP 600 Series Bridge PIDU Plus to the ODU can be any
standard CAT5e type provided that it is suitable for outdoor deployment. Motorola
recommends that cables to the specification below be used:
Cable:
Superior Essex BBDGE CAT 5e
Connector Type:
Tyco, 5-569278
Gland:
Motorola WB1811
CAUTION: Failure to use the recommended (or equivalent) standard of cable may invalidate
the system’s safety certification.
The cable used to connect the PTP 600 Series Bridge PIDU Plus to the users Network
Equipment can be any standard CAT5e Cable.
42
3 Getting Started
The PIDU Plus to ODU and the PIDU Plus to Network Equipment cables may be unscreened
(UTP) or screened (STP). However, unscreened cables reduce the system’s ability to cope
with nearby lightning strikes. If lightning activity is common in the area of deployment, the use
of screened cable is highly recommended. See Section 11 “Lightning Protection”.
The PIDU Plus provides screen continuity between the ODU and Network Equipment
connections.
NOTE: The ODU network connection implements automatic MDI/MDI-X sensing and pair
swapping allowing connection to networking equipment that require cross-over cables (MDI-X
networks) or straight-through cables (MDI Networks).
3.3.6
PTP and Lightning Protection
The PTP 600 Series Bridge PIDU Plus meets the low level static discharge specifications
identified in Section 20 “Specifications”, but does not provide lightning or surge suppression.
Installations will generally require lightning or surge suppression, a separate Ethernet surge
suppressor must be used and appropriately earthed. Suitable surge suppressors can be
sourced from your Motorola Point-to-Point Distributor or Solutions Provider. See Section 11
“Lightning Protection”.
3.3.7
Mounting Brackets
The PTP 600 Series Bridge is supplied with a mounting bracket suitable for mounting the
ODU to a pole of 50mm (2”) to 75mm (3”) in diameter. For more details on mounting, see
Section 7 “Installation”.
The bracket allows for adjustment in both azimuth and elevation. The bracket may be split
allowing the pole mount section of the bracket to be mounted to the pole first. This allows the
installer to take the weight of the unit and secure it, one handed, with a single mounting bolt.
The PIDU Plus can either be desk or wall mounted. The preference is wall mounted with the
cables dressed to a cable channel. Wall mounting is achieved by screwing through the
mounting lugs on either side of the unit. Remember to leave space for access to the
Recovery button. See Section 3.3.2 “PIDU Plus – PTP 600 Series Bridge”.

3 Getting Started
3.3.8
Configuration and Management
Configuration and Management of the PTP 600 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 600 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”.
3.4

4.1
Radio Link
The PTP 600 Series Bridge consists of an identical pair of units deployed one at each end of
the link. The radio link operates on a single frequency channel in each direction using Time
Division Duplex (TDD). One unit is deployed as a master and the other as a slave. The
master unit takes responsibility for controlling the link in both directions.
The non-line-of-sight (NLOS) aspects of the product are provided by Multiple-Input MultipleOutput (MIMO), coupled with Orthogonal Frequency Division Multiplexing (OFDM)
modulation.
4.2
Frequency Bands
The PTP 600 Series Bridge has been developed to operate within license exempt frequency
bands as well as the licensed 2.5GHz band in the USA. The current product range supports:
•
USA BRS-EBS Post-Transition band 2.5 GHz (2496 – 2690 GHz)
•
ETSI 5.4 GHz band B (5.470-5.725 GHz)
•
ETSI 5.8 GHz band C (5.725–5.850 GHz) and the USA 5 GHz ISM band (5.725-5.850
GHz)
•
US Federal 4.5 GHz band (4.404-4.596 GHz)
•
USA and Canada Public Safety 4.9 GHz band
•
Military 4.9 GHz band
•
5.9 GHz band (5.825-5.925 GHz)
The PTP 600 Series Bridge has been designed to coexist with other users of the band in an
optimal fashion using a combination of Transmit Power Control (TPC), Spectrum
Management functionality and Antenna beam shape. In order to maintain link availability, the
product employs adaptive modulation techniques that dynamically reduce the data rate in
severe or adverse conditions.
45
4 Product Architecture
4.3
Ethernet Frames
The PTP 600 series provides wireless Ethernet bridging between two fixed locations. To be
more precise, it forwards Ethernet frames as a two-port transparent heterogeneous
encapsulation bridge, meaning that each bridge forwards frames between two dissimilar
interfaces (Ethernet and wireless), encapsulating Ethernet MAC frames within a PTP MAC
frames for transmission at the wireless interface. A link consisting of a pair of back to back
bridges appears to the data network to be very similar to a standard two-port Ethernet bridge.
The PTP600 series provides two egress queues in each direction, classifying Ethernet frames
into one of the two prioritised queues based on inspection of the user priority field (802.1p) in
in a customer (IEEE802.1Q) VLAN tag or provider (IEEE802.1ad) VLAN tag. Untagged frames
receive a default priority. The queuing method is strict priority. The bridge does not implement
any VLAN functions for bridged frames apart from inspection of the priority field, and
consequently the bridge forwards tagged and untagged Ethernet frames regardless of VLAN
ID and without modification of any protocol header fields.
The PTP 600 series supports a maximum Ethernet frame size of 2000 bytes for bridged
traffic.
4.4
Management Function
The management function of the PTP 600 Series Bridge is logically equivalent to a separate
protocol stack with virtual point of attachment at the Ethernet interface. This is illustrated in
Figure 12.
Figure 12 – PTP 600 Series Bridge Layer Diagram
46
4 Product Architecture
Each unit in the link is manageable through an IP connection. Standard IP protocols are
utilized for all management functions, for example, HP, SNMP, etc. The unit can be
configured to use a VLAN with a single C-tag or S-tag on the management interfaces.
4.5
Channel Bandwidth and Link Symmetry Control
The PTP 600 series provides configurable channel bandwidth in the radio link (5 MHz, 10
MHz, 15 MHz and 30 MHz), and configurable fixed and adaptive link symmetry. Fixed link
symmetry supports:
•
2:1
•
1:1
•
1:2
Channel bandwidth 5 MHz supports link symmetry 1:1 only.
4.6
Upgradeable Software
The PTP 600 Series Bridge is fully software upgradeable. New software images are first
downloaded from the Motorola website http://www.motorola.com/ptp to a convenient
computer. The image is then uploaded to the ODU via the web management page described
in Section 8.3.6 “Software Upgrade”. The compressed image is first loaded into RAM and
check-summed. If the compressed image transfer has completed successfully the image is
decompressed and written to flash memory. On completion of this process the unit can be
rebooted to use the newly uploaded image. Should this process fail, the unit will revert to a
protected compressed image installed during manufacturing to allow the unit to be recovered.

5 General Considerations
NOTE: For PTP 54600, PTP 58600 and PTP 59600, use of the product is allowed according
to local regulations.
There are two alternative methods of spectrum planning:
•
First an operator can utilize the default spectrum management mode i-DFS (intelligent
Dynamic Frequency Selection). This mode uses the PTP 600 Series Bridge ability to
measure the interference levels in all channels to build up a picture of the interference /
noise levels in all channels. The PTP 600 Series Bridge uses statistical techniques to
select the most appropriate transmit and receive channels. The i-DFS mode can be
influenced in its channel decision process by selectively barring channels from use. The
use of this functionality is described in detail in Section 8.3.7 “Spectrum Management”.
•
Second, when detailed control of the spectrum allocation is required, it is recommended
that the fixed frequency mode is used to statically allocate transmit and receive channels.
CAUTION: These methods must not be used when Radar Detection is enabled.

5.2
Licenses and Region Codes
The PTP 600 Series Bridge uses a system of Region Codes to control the operation of the
radio link. The Region Code is set by a License Key.
CAUTION To meet the regulatory requirements of your region you should set the correct
Region Code by obtaining a new License Key from your reseller or distributor.

5 General Considerations
NOTE: The 5.8 GHz license for India is addressed using both PTP 58600 and PTP 59600
frequency variants.
When shipped from the factory units are configured as follows:
•
PTP 25600 – Region Code 16
•
PTP 45600 – Region Code 23
•
PTP 54600 – Region Code 26
•
PTP 58600 – Region Code 1
•
PTP 59600 – Region Code 16
The Deployment Guide for PTP 54600 also contains the license keys for region 12 and 13.
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, that is, Fixed
Frequency operation is not allowed.
Radar avoidance is not applicable to the PTP 25600 product or the PTP 45600 product.
To address the primary aims, the Spectrum Management algorithm implements a radar
detection function which looks for impulsive interference on the operating channel only. If
impulsive interference is detected, Spectrum Management will mark the current operating
channel as having detected radar (unavailable channel) and initiate a channel hop to an
available channel. The previous operating channel will remain in the unavailable state for
thirty minutes after the last impulsive interference pulse was detected. After the thirty minutes
have expired the channel will be returned to the usable channel pool.
Note that PTP 25600, PTP 45600, PTP 54600, PTP 58600 and PTP 59600 are different products.
54
5 General Considerations
The equipment can only transmit on available channels, of which there are none at initial
power up. The radar detection algorithm will always scan a usable channel for 60 seconds
for radar interference before making the channel an available channel. This compulsory
channel scan will mean that there is 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.
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 13. Barred channels
are indicated by a “No Entry” symbol displayed on the “Spectrum Management” web page,
see Section 8.3.9 “Spectrum Management Control - With Operational Restrictions”.
NOTE: “Radar Avoidance Enabled” is only valid with 30 MHz channel bandwidth.
Figure 13 - 5.8 GHz UK RTTT Channel Avoidance – 30 MHz Channel Bandwidth Only
55
5 General Considerations
5.3.3
Radar Avoidance, i-DFS and Variable (Narrow) Bandwidth Operation
PTP 600 Series bridges do not support operation with 5, 10 or 15 MHz channel bandwidth in
regions where radar avoidance is enabled.
NOTE: Radar avoidance requirements in the 5.4GHz band in the EU is detailed in
specification EN 301-893 version 1.4.1 and in the US in the specification FCC part 15.437.
Radar avoidance at 5.8GHz is applicable to EU operation and the requirements are currently
as defined in EN 302 502.
5.4
Variable Channel Bandwidth Operation
Channel bandwidths of 5, 10, 15 and 30MHz are supported for Full versions of the PTP 600.
Lite versions of the PTP 600 products support only channel bandwidths of 10, 15 and 30
MHz.
Configuration of the variable bandwidth operation must be symmetric, that is, the Transmit
and receive channels must use identical channel bandwidths.
5.5
PTP 25600 Specific Frequency Planning Considerations
The supported 2.5GHz frequency range is split into three bands, according to the bands
specified in the FCC BRS-EBS Post-Transition Band plan :
•
Lower: 2496 MHz to 2572 MHz with a 5.5MHz channel raster (76 MHz total).
•
Middle: 2572 MHz to 2614 MHz with a 6 MHz channel raster (42 MHz total).
•
Upper: 2618 MHz to 2690 MHz with a 5.5 MHz channel raster (76 MHz total).
NOTE: For the PTP 25600 product variant, the unit will only operate in Fixed Frequency
mode, and the user is unable to select i-DFS.
30MHz channel widths are available where allowed by local regulations and subject to some restrictions on
channel choice.

PTP 58600 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 600 Series Bridge solution reduces the power when
operating at the edge channels. The amount of reduction, if any, is dependant on the region
code of the region of operation. This currently only affects systems configured with Region
Code 1. The power reduction in the edge channels for 5 MHz, 10 MHz and 15 MHz is
presented in Table 14 (for region code 1 ONLY).

PTP 59600 Specific Frequency Planning Considerations
Adjustment of the lower center frequency allows the operator to slide the available frequency
settings up and down the 5.9 GHz bands. Figure 27 to Figure 30 show the available spectrum
depending on the channel width (30 MHz, 15 MHz, 10 MHz and 5 MHz respectively).

5.10.1 PTP 59600 Raster Considerations
The PTP 59600 variant operates on a 10 MHz channel raster (for 30 MHz channel bandwidth)
and 6 MHz for the variant channel bandwidths 5, 10 and 15 MHz. The channel raster is set to
even center frequencies. See Figure 27 to Figure 30.

Time Division Duplex (TDD) Synchronization
5.11.1 Introduction
In a TDD system, a radio transmits for a portion of the radio frame and receives in a different
portion of the frame. Motorola PTP600 links consist of a Master unit and a Slave unit with the
Master transmitting for the rst part of the radio frame (Slave receiving) and the Slave
transmitting in the remainder of the radio frame (Master receiving). The portion of the frame
apportioned to each period can be dynamic, for example in IP optimisation mode where the
split is a function of the offered traffic in each direction. However, if the frames of the two links
are not aligned in time, then an interference mechanism exists where one Master unit may be
transmitting when the Master unit from the other link is receiving. A similar mechanism exists
for Slave units. The level of interference becomes very signicant when the units are located in
close proximity, for example when units are located on the same mast. This problem is
illustrated in Figure 31 where it can be seen that transmissions from Master unit A overlap
with the receive portion of Master unit B and vice versa.
Figure 31 - Co-location of Links Interference Problem - A Simple Example
71
5 General Considerations
Interference can be minimised by increasing the radio channel separation between units
which are in close proximity, for example for units on the same mast. This may not always be
possible if the mast is hosting a large number of links and if spectrum is limited. Also, the
achieved reduction may not always be sufficient. Another way to reduce interference is to
reduce the transmit power of an interfering radio. Again, this may not always be possible if the
link causing the interference does not itself have sufficient radio gain margin to allow the
power of its radios to be reduced.
5.11.2 TDD Synchronization
TDD synchronization overcomes these issues by aligning the radio frame of all links in the
network such that all Master units transmit at the same time and receive at the same time.
This eliminates interference between units on the same mast if the units on the mast are
configured as Master units. This illustrated in Figure 28 where the frames of the two links are
aligned in time.
Figure 32 TDD Synchronization And Co location Example
Due to propagation delay, a mechanism exists where an interfering signal from a remote
Master unit arrives at a victim Master delayed in time. This would occur when Master units
are installed on different masts. Similarly, an interfering signal from a remote Slave unit will
arrive at a victim Slave unit delayed in time. Correct configuration of TDD synchronization
ensures that the delayed signals do not overlap with the receive portion of the victim frame. In
order to eliminate the interference from delayed signals, the configuration and the resulting
TDD frame structure will actually depend upon characteristics of the overall network such as
the longest link and the maximum distance between interfering Master units and interfering
Slave units. The installation wizard requests that these parameters are entered when TDD
synchronization is enabled. This is covered in detail in Section 14 “TDD Synchronization
Configuration and Installation Guide”.
72
5 General Considerations
5.11.3 Implementation of TDD Synchronization
TDD synchronization is achieved by connecting each Master unit to a GPS Synchronization
Unit. Installation details are covered in Section 14 “TDD Synchronization Configuration and
Installation Guide”. The GPS unit provides the Master unit with a precise 1Hz signal where
the leading edge occurs at the same point in time for all units in the network which have been
locked to the GPS Satellite system. The Master radio then aligns its radio frame to start on
the leading edge of the 1Hz signal.
5.11.4 System Constraints with TDD Synchronization Enabled
The following constraints apply when TDD synchronization is enabled:
•
As the radio frame needs to be aligned across the network, the apportioning of the frame
between the two link directions can no longer be dynamic. The split is fixed at 50:50.
•
In order that the start of the radio frame can always align with the leading edge of the 1Hz
signal, the radio frame duration must be an integer fraction of 1s. The exact frame length
is calculated by the installation wizard as a function of the network characteristics such as
longest link, and longest distance between interfering masters and interfering slaves.
•
TDD synchronisation is a feature which enables a network of links to co-exist. A major
part of network design is concerned with frequency planning which is required in order to
minimise interference between links. It is therefore reasonable that when TDD
synchronisation is enabled, the radio is configured for a specific fixed frequency selected
as part of the network design. As such, Intelligent Dynamic Frequency Selection (iDFS) is
disabled.
•
It is not possible to enable TDD synchronisation in regions where radar avoidance is
enabled. This is because radar avoidance requires the random selection of frequency
after detection, rather than a fixed frequency which is selected as part of a network
design.
73
5 General Considerations
5.12
Distance
The PTP 600 Series Bridge will operate at ranges from 100 m (330 ft) to 200 km (124 miles),
within 3 modes: 0-40km (0-25 miles), 0-100km (0-62 miles) and 0-200km (0-124 miles).
Operation of the system will depend on obstacles in the path between the units. Operation at
40 km (25 miles) or above will require a near line-of-sight path. Operation at 100m (330 ft)
could be achieved with one unit totally obscured from the other unit, but with the penalty of
transmitting at higher power in a non-optimal direction, thereby increasing interference in the
band. This subject is covered in more detail in Section 6.1.3 “Path Loss Considerations“.
5.13
Networking Information
The PTP 600 Series Bridge operates as a transparent Ethernet bridge. Although each unit
requires an IP address, this IP address is for management purposes only, and it plays no part
in the forwarding of bridged Ethernet frames. IP addresses are assigned during initial
configuration as described in Section 7.2 “Installation Procedure”.
5.14
Lightning Protection
The amount of lightning protection is dependent on regulatory requirements and the end user
requirements. The standard ODU for the PTP 600 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.
CAUTION: Motorola recommends the use of screened cable and Lightning Protection units to
protect connected equipment from nearby strikes.
NOTE: The PTP 600 Series Bridge is not designed to survive direct lightning strikes. For this
reason the unit should not be installed as the highest point in a localized area, unless specific
precautions are taken. See Section 11 “Lightning Protection”.
5.15
Electrical Requirements
The PTP 600 Series Bridge requires one mains supply outlet at each end of the link to plug in
the PIDU Plus units. See Section 3.3.2 “PIDU Plus – PTP 600 Series Bridge”.

Site Selection Criteria
The following are guidelines for selecting the installation location of the ODU and PIDU Plus
for a PTP 600 Series Bridge.
6.1.1
ODU Site Selection
When selecting a site for the ODU the following should be taken into consideration:
•
It is not possible for people to stand or walk inadvertently in front of the antenna
•
Height and location to achieve the best radio path
•
Height in relation to other objects with regard to lightning strikes
•
Aesthetics and planning permission issues
•
Distance from the ODU and connected Network equipment (Maximum cable run from the
ODU to the connected equipment is 100m [330 ft])
•
Distance from the PIDU Plus to the ODU (Maximum cable run from the PIDU Plus to the
ODU is 300m [990 ft] when using the Fiber interface)
•
If using the GPS Sync Unit, ensure that it is exposed to an unobstructed path to the sky.
Please refer to the “GPS Synchronization Unit Kit” User Manual delivered with the kit.
6.1.2
PTP 600 Series Bridge PIDU Plus Site Selection
When selecting a site for the PIDU Plus the following should be taken into consideration:
•
Availability of a mains electricity supply
•
Accessibility for viewing status indicators and pressing Recovery switch.

6.1.3
Path Loss Considerations
The path loss is the amount of attenuation the radio signal undergoes between the two ends
of the link. The path loss is the sum of the attenuation of the path if there were no obstacles in
the way (Free Space Path Loss), the attenuation caused by obstacles (Excess Path Loss)
and a margin to allow for possible fading of the radio signal (Fade Margin).

Definitions
The equipment capability is given in Table 15 to Table 24. Each table gives Link Loss, Output
Power and System Thresholds for PTP 600 Series Bridge in all modulation modes for all
channel bandwidths (5 MHz, 10 MHz, 15 MHz and 30 MHz). Adaptive Modulation will ensure
that the highest throughput that can be achieved instantaneously will be obtained taking
account of propagation and interference. The calculation of Equation 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.
For minimum error rates on TDM links the maximum modulation mode should be limited to
64QAM 0.75.
The values for (BPSK) are static receive sensitivity measurements. The other values are
static receive sensitivity measurements with an AMOD threshold applied. The AMOD
threshold applied is for a benign radio channel.
76
6 Site Planning
Sensitivity: Sensitivity is defined as the combined receive input signal level on both
-7
horizontal and vertical inputs that produces a Null BER Error ratio of 3x10 .
Output Power: The output power is for a centre channel in Region 1. The output power will
be reduced on the edge channels and may vary if different region codes are selected.
AMOD Threshold: The AMOD threshold is the combined receive input signal level on both
horizontal and vertical inputs that results in the link consistently entering the receive
modulation mode under consideration as the signal level is increased.
System Threshold: Thresholds for all modes except BPSK are for the relevant link
optimization AMOD thresholds. System threshold for BPSK is the RPSK receive sensitivity.
Max Link Loss: The maximum link loss for each modulation mode is derived from the AMOD
threshold for that mode (sensitivity threshold for BPSK) and the maximum Region 1 centre
channel output power. The figures assume integral antennas with 23 dBi (5.9 GHz, 5.8 GHz
and 5.4 GHz) or 18 dBi (2.5 GHz) gain are used.

Mounting the ODUs
The ODU mounting bracket is designed to ease installation by fixing the bracket to a pole and
then bringing the ODU into position using a single bolt fixing. The ODU should be mounted
using the following steps ensuring that the cable entry is at the bottom.
The ODU mounting bracket is designed to work with poles with diameters in the range 50mm
(2”) to 75mm (3”).
Figure 33 - Mounting to pole diameters 25mm (1”) to 50mm (2”)
Step 2: Mate the unit to the bracket together
and tighten the nut and bolt.
Step 1: Mount the bracket to the pole.
Pole diameters of 25mm (1”) to 50mm (2”) can be accommodated by inverting the back of the
bracket as shown in Figure 33.
When adjustment is complete tighten all bolts to 14Nm (11lb ft).
CAUTION: Do not over tighten the bolts as bracket failure may occur.
The enclosure and mounting brackets of the PTP 600 Series Bridge product range are
capable of withstanding wind speeds up to 151mph (242kph). The installer should ensure that
the structure the bridge is fixed to is also capable of withstanding the prevalent wind speeds
and loads. See Section 12 “Wind Loading”.

WARNING: 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 34 - Integral Safety Loop
The length of the safety lanyard must not exceed 1m (approx 3 ft) in length. The lanyard
should be made from a material that does not degrade in an outdoor environment.
The safety lanyard must be fixed to a separate fixing point that is not part of the direct
mounting system for the ODU.

Connecting Up
7.7.1
Preparing the PIDU Plus To ODU Cable
NOTE: The maximum cable length between the ODU and the user’s Network Equipment is
100m (330 ft). Cable lengths up to 300m (984 ft) can be used where the PIDU Plus to ODU
cable is supplying power only, that is, when using the PTP 600 Series Bridge Optical
Interface.
The cable should be assembled as shown in Figure 35:
Figure 35 - Correct Cable Preparation for the Recommended Cable
92
7 Installation
CAUTION: Check that the crimp tool matches the RJ45 connector being used.
Both ends of the ODU cable are terminated in the same way. The above procedure should be
repeated for the PIDU Plus end of the cable when the cable routing process is complete. This
assumes that the installation uses PTP LPUs. If not, then the PIDU Plus end of the cable
does not require a Gland, but just the RJ45.
NOTE: The PIDU Plus end of the cable does not employ a cable gland.
Figure 36 shows a completed ODU to PIDU Plus cable.
Figure 36 - Completed ODU Connector
CAUTION: Do not over tighten the glands as the internal seal and structure may be
damaged. See Figure 37 for an example of an over tightened cable gland.

7.7.3
Making the PTP 600 Series Bridge PIDU Plus Connection At The ODU
The following procedure describes how connection is made at the ODU. It is often easier to
carry out this procedure on the ground or a suitable surface prior to mounting the ODU.
Ensure that no power is connected to the PIDU Plus or present on the cable before
connecting the ODU.
Figure 39 - Connecting the PIDU+ to the ODU
Step 1: Assemble the cable as described in
7.7.1 above
Step 2: Insert the RJ45 connector making
sure that the locking tab snaps home
Step 3: Screw in the body of the weather
proofing gland and tighten
Step 4: Screw on the clamping nut and tighten
(Do not over tighten – see Figure 37)
95
7 Installation
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 40 - Disconnecting the ODU
CAUTION: Ensure that power is removed from the system at the PIDU Plus to prevent
damage to the ODU while making or breaking the connection.
7.7.4
Routing the Cable
After connecting the cable to the ODU it can be routed and secured using standard cable
routing and securing techniques. When the cable is in place it can then be cut to the desired
length at the PIDU Plus prior to connection to the PIDU Plus.
7.7.5
Fitting a Lightning Protection Unit
If you have opted to fit a Lightning Protection unit, this should be installed by following the
manufacturer’s instruction. For recommended types see Section 11 “Lightning Protection”.
96
7 Installation
7.7.6
Grounding the Installation
The Outdoor Unit (ODU) must be properly grounded to protect against power surges. It is the
user’s responsibility to install the equipment in accordance with Section 810 of the National
Electric Code, ANSI/NFPA No.70-1984 or Section 54 of the National Electrical Code in the
country of installation. These codes describe correct installation procedures for grounding the
outdoor unit, mast, lead-in wire and discharge unit, size of grounding conductors and
connection requirements for grounding electrodes. It is recommended that installation of the
outdoor unit be contracted to a professional installer.
7.7.7
Making the ODU Connection at the PTP 600 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 from
inadvertently plugging other equipment into the ODU RJ45 socket.
CAUTION: Plugging other equipment into the ODU RJ45 socket may damage the equipment
due to the non-standard techniques employed to inject DC power into the 1000BaseT
connection between the PIDU Plus and the ODU. Plugging the ODU into other equipment
may damage the ODU and/or the other equipment.
Step 1: Undo the retaining screw and hinge
back the cover.
97
Step 2: Plug in the ODU into the PIDU Plus Cable
ensuring that it snaps home
7 Installation
Step 3: Replace the cover and secure with the retaining screw
7.7.8
Making the Network Connection at The PIDU Plus – PTP 600 Series Bridge
The Network connection is made by connecting the user’s Network Equipment directly to the
PIDU Plus LAN port as shown in Figure 41.
Figure 41 - Making the Network Connection at the PIDU Plus
98
7 Installation
7.7.9
Mounting the PTP 600 Series Bridge PIDU Plus
This step is optional. Motorola recommends that you mount the PIDU Plus on a wall or other
suitable mounting surface. This prevents the unit from being knocked or kicked and can help
maintain link availability. Ensure that the Recovery switch can be accessed when mounting
the unit.
Step 1: Fix the PIDU Plus to the wall using the lugs provided.
Step 2: Make connections as per Section 7.7.7 “Making the ODU
Connection at the PTP 600 Series Bridge PIDU Plus”
CAUTION: The PIDU Plus is not waterproof and should be mounted away from sources of
moisture. If mounted outdoors, the unit should be mounted in a rain proof enclosure,
preferably ventilated.
99
7 Installation
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. This is shown in Figure 42. 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 42 – PTP 600 Series PIDU Plus Drip Loop Configuration
CAUTION: It is possible for moisture to enter the cable due to damage to the outer protective
layer. This moisture can track down the inside of the cable, filling up the drip loop and
eventually finding its way into the PIDU Plus. To protect against this the outer protective layer
of the cable can be opened up at the bottom of the drip loop to allow this moisture to escape.

7 Installation
7.7.10 Powering Up
The PTP 600 Series Bridge is supplied as a pair of matched Master/Slave units. The Master
unit can now be powered up and accessed using the default URL http://169.254.1.2/; the
Slave unit can be accessed using http://169.254.1.1/.
Prior to powering up the PTP 600 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 8.3.4 “Install Pages”. It is recommended that this procedure be carried out on
the bench before physical installation commences. Providing it is safe to do so, the installer
should take the process to the point where a radio link is established before proceeding to the
installation site.
NOTE: It is possible that some units may not be accessed using the above default URL. This
is because these units may have been previously configured with IP addresses 10.10.10.11
(Master) and 10.10.10.10 (Slave). Therefore, users must use the URL http://10.10.10.10/
and/or URL http://10.10.10.11/ to configure the units. Please ensure that a computer with web
browsing capabilities is configured with an IP address of 10.10.10.n, where n is any value
between 2 and 254 but excluding 10 and 11, to configure these units.

7.7.11 Aligning the PTP 600 Series Bridge ODUs
The following is a description of the steps taken to establish a radio link between the two
units forming the bridge and align the units for the best signal strength.
The PTP 600 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 achieved . The tones and their meanings are as follows:
Table 25 - Audio indications from the ODU
State Name

Rx Power
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.
The pitch of the alignment tone is proportional to the received power of the wireless signals. The best results
are usually achieved by making small incremental movement in angular alignment.
102
7 Installation
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.
There is a graphical installation screen (section 8.3.5 “Graphical Install”) available using the
web interface that displays the state of the link during the alignment process (up = green,
down = red).
The following behavior should be noted:
•
When first started up and from time to time, the Master unit will carry out a band scan to
determine which channels are not in use. During this time, between 10 and 15 seconds,
the Master unit will not transmit and as a consequence of this neither will the Slave unit.
During this time the installation tone on the master unit will drop back to the band scan
state, and the Slave unit will drop back to the Scanning state with the pitch of the tone set
to the background noise level. Alignment of the unit should cease during this time.
•
The master unit can take up to 60 seconds in 0-40km (0-25 miles) mode, 90 seconds in
0-130km (0-81 miles) mode and 120 seconds in 0-200km (0-124 miles) mode to
determine the range of the link being installed 8. 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.
If the unit is operating where mandatory radar avoidance algorithms are implemented the ranging behaviour for
the PTP 600 Series Bridge may be affected. The Master has to monitor the initially chosen channel for 60
seconds to make sure it is clear of radar signals before transmitting. If a radar is detected during any of the
installation phases a further compulsory 60 seconds channel scan will take place as the master unit attempts to
locate a new channel that is free of radar interference
103
7 Installation
When the alignment process is complete the installer MUST REMEMBER TO DISARM
BOTH UNITS in the link as described in Section 8.3.4 “Install Pages”. This is necessary in
order to:
•
Turn off the audible alignment aid (section 8.3.4.5 “Disarm”)
•
Enable Adaptive Modulation
•
Fully enable Advanced Spectrum Management with i-DFS
•
Clear unwanted installation information from the various systems statistics
•
Store the link range for fast link acquisition on link drop
•
Enable higher data rates
After 24 hours, the units will be disarmed automatically provided that they are armed and that the link is UP.

8.1
Home Page – PTP 600 Series Bridge
The home page for the PTP 600 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
44) normally displays four key system attributes:
Wireless Link Status: The Wireless Link Status attribute displays the current status of the
PTP 600 Series Bridge wireless link. A state of ‘Up’ on a green background indicates that a
point-to-point link is established. A state of ‘Down’ on a red background indicates that the
wireless link is not established. If the link is down for an unknown reason the system
administrator should first consult the status web page for a more detailed summary of up to
date system diagnostics.
Link Name: The link name attribute is a name and/or handle allocated by the system
administrator to aid the identification of the unit, network or building.
Figure 44 - System Summary Page
Elapsed Time Indicator: The elapsed time indicator attribute presents the total time in days,
hours, minutes and seconds since the last system restart. The system can restart for several
reasons, for example, commanded reboot from the system reboot webpage, or a power cycle
of the equipment.
System Clock: If SNTP (Simple Network Time Protocol) is enabled, or the clock has been
set, then a system clock attribute is displayed giving the date and time of the last page
refresh. Section 8.3.11.8 “SNTP (Simple Network Time Protocol)” explains how to enable
SNTP and Section 8.3.11.9 “Setting the clock” explains how to set the clock.

8 Web Page Reference
The following system alarms are defined:
Ethernet Link Status: Current status of the Ethernet link. If there are any problems with the
Ethernet interface, this alarm will be asserted. This alarm will most likely be seen if the unit
has no Ethernet cable plugged into its Ethernet socket. Note that a change of state may
generate an SNMP trap and/or SMTP email alert.
Telecoms Channel A Status (see section 8.3.4.3 “Telecoms Interface” for a description
of the Telecoms Interface): Current status of telecoms channel A. Indicates that there is a
problem with the telecoms channel A. Possible problems are "No Signal (local)", "No Signal
(Remote)", and "No Signal (Local and Remote)". Note that a change of state may generate an
SNMP trap and/or SMTP email alert.
Telecoms Channel B Status (see section 8.3.4.3 for a description of the Telecoms
Interface): Current status of telecoms channel B. Indicates that there is a problem with the
telecoms channel B. Possible problems are "No Signal (local)", "No Signal (Remote)", and
"No Signal (Local and Remote)". Note that a change of state may generate an SNMP trap
and/or SMTP email alert.
Telecoms Interface A Loopback (see section 8.3.4.3 for a description of the Telecoms
Interface): The loopback status of telecoms channel A. This is intended for installation testing
and should be set to 'None' for normal operation. The wire connections to a unit can be tested
by applying a 'Copper' loopback to the local unit. The wireless connection to the remote unit
can be tested by applying a 'Wireless' loopback to the remote unit with no loopback on the
local unit. Note that a change of state may generate an SNMP trap and/or SMTP email alert.
The loopback can be disabled from the telecoms configuration sub menu (see Section
8.3.1.6).
Telecoms Interface B Loopback (see section 8.3.4.3 for a description of the Telecoms
Interface): The loopback status of telecoms channel B. This is intended for installation testing
and should be set to 'None' for normal operation. The wire connections to a unit can be tested
by applying a 'Copper' loopback to the local unit. The wireless connection to the remote unit
can be tested by applying a 'Wireless' loopback to the remote unit with no loopback on the
local unit. Note that a change of state may generate an SNMP trap and/or SMTP email alert.
The loopback can be disabled from the telecoms configuration sub menu (see Section 8.3.1.6
“Telecoms Configuration Page”).
Region Code: The region code prohibits the wireless unit from operating outside the
regulated limits. An invalid region code indicates a corrupted license key. Note that a change
of state may generate an SNMP trap and/or SMTP email alert.
109
8 Web Page Reference
Install Status: A non-OK value indicates that signaling was received with the wrong MAC
address. Note that it is very unusual to detect this, because units with wrongly configured
Target MAC Address will normally fail to establish a wireless link. However, rare
circumstances may establish a partial wireless link and detect this situation. NB: A non-OK
value on start-up, or a change of value during operation, may generate an SNMP trap and/or
SMTP email alert.
Install Arm State:
This alarm warns when a wireless unit is in installation mode. After
installation the wireless unit should be disarmed. This will increase the wireless link’s datacarrying capacity and stop the installation tone generator. The wireless link is disarmed from
the ‘Installation Wizard’ see Section 8.3.4.5 “Disarm”. A change of state may generate an
SNMP trap and/or SMTP email alert.
Unit Out Of Calibration: The unit is out of calibration and must be returned to the factory
using the RMA process for re-calibration.
Encryption Enable Mismatch (see section 17 “AES Encryption Upgrade”): Encryption has
been enabled on one end of the wireless link but not the other.
Incompatible Region Codes: The PTP 600 Series Bridge uses region codes to comply with
local regulatory requirements governing the transmission of wireless signals in the 5.9 GHz,
5.8 GHz, 5.4 GHz, 4.5 GHz and 2.5 GHz bands. Region codes can only be changed by
obtaining a new PTP600. Note that a change of state may generate an SNMP trap and/or
SMTP email alert.
Series license key: If this alarm is encountered the appropriate license keys from the country
of operation should be obtained from your distributor. Applying license keys containing the
same region codes to both ends of the link will remove the alarm.
No Wireless Channel Available: Spectrum Management was unable to locate a suitable
wireless channel to operate on. Note that a change of state may generate an SNMP trap
and/or SMTP email alert.
Wireless Link Disable Warning: This warning is displayed if the Wireless link has been
administratively disabled via the SNMP Interface (see Section 8.3.11 “Remote Management
Page”). The Wireless Interface MIB-II ifAdminStatus attribute has been set to DOWN. To
enable the Ethernet interface, set the ifAdminStatus attribute to UP. Note that a change of
state may generate an SNMP trap and/or SMTP email alert.
110
8 Web Page Reference
Ethernet Link Disable Warning: This warning is displayed if the Ethernet link has been
administratively disabled via the SNMP Interface (see section 8.3.11 “Remote Management
Page”). The Ethernet Interface MIB-II ifAdminStatus attribute has been set to DOWN. To
enable the Ethernet interface, set the ifAdminStatus attribute to UP. Note that a change of
state may generate an SNMP trap and/or SMTP email alert.
Fiber Link Status: If the fiber link is not OK, there are two possible causes: Either the fiber
link has been installed but disabled (because the license key does not include fiber support),
or the link could not be established even though an optical carrier was detected (due perhaps
to a broken TX fiber, or the link is disabled at the fiber link partner). Note that a change of
status may generate an SNMP trap and/or SMTP email alert.
Ethernet Configuration Mismatch Alarm: The detection of Ethernet fragments (runt
packets) when the link is in full duplex is an indication of an auto-negotiation or forced
configuration mismatch. Note that a change of state may generate an SNMP trap and/or
SMTP email alert.
Incompatible Master and Slave: A non-zero value indicates that the master and slave ends
of the wireless link are different hardware products, or have different software versions. Note
that it is very unusual to detect this because incompatible units will normally fail to establish a
wireless link. However, some combinations may establish a partial wireless link and detect
this situation. Note that a non-zero value may generate an SNMP trap and/or SMTP email
alert.
TDD Synchronization Status: Current status of the TDD Synchronization (acquiring
synchronization, no timing reference and timing system not connected). Note that a change of
state may generate an SNMP trap and/or SMTP email alert.
SNTP Synchronization failed: This warning indicates that SNTP has been enabled but that
the unit is unable to synchronize with the specified SNTP server. Section 8.3.11.8 “SNTP
(Simple Network Time Protocol)” explains how to configure SNTP. Note that a change of
state may generate an SNMP trap and/or SMTP email alert.

8.2
Systems Status Page
The status page has been designed to give the system administrator a detailed view of the
operation of the 600 Series Bridge from both the wireless and network perspectives.
The page is subdivided into four main categories Equipment, Wireless, Telecoms and
Ethernet/Internet. The ‘Equipment’ section contains the unit’s inventory and identification
information. The ‘Wireless’ section presents the key wireless metrics, which are displayed as
a series of measurements. The ‘Ethernet/Internet’ section describes the unit’s network identity
and connectivity. “Telecoms” controls the unit’s E1/T1 telecoms interfaces.
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 600 Series Bridge at this
interval.
The two PTP 600 Series bridges units are arranged in a master and slave relationship. The
roles of the units in this relationship are displayed in the page title. The master unit will always
have the title ‘- Master’, and the slave will always have ‘- Slave’ appended to the ‘Systems
Status’ page title.
Figure 46 - Status Page
112
8 Web Page Reference
The following section details all the attributes displayed on the status page:
Link Name: The link name is allocated by the system administrator and is used to identify the
equipment on the network. The link name attribute is limited to a maximum size of 63 ASCII
characters.
Link Location: The link location is allocated by the system administrator and can be used as
a generic scratch pad to describe the location of the equipment or any other equipment
related notes. The link location attribute is limited to a maximum size of 63 ASCII characters.
Software Version: The attribute describes the version of software installed on the
equipment. The format of the attributes is FFSSS-XX-YY where FF is the frequency variant
(2.5, 4.5, 5.4, 5.8 or 5.9 GHz), SSS is the System Release, XX is the major release version
and YY is the minor release version.
Hardware Version: The hardware version attribute contains all the combined hardware
version information. The attribute is formatted as DXX-RYY-Z where DXX contain the version
of the digital card, RYY contains the version of the RF (radio frequency) card and Z describes
the antenna type which can be I (integrated) or C (connectorized).
Region Code: The region code is used by the system to constrain the wireless to operate
within regulatory regime of the particular country. The region code is encoded in the product
license key. If the operator wishes to change region code, a new license key must be
obtained from Motorola or the local point-to-point distributor / system integrator.
Elapsed Time Indicator: The elapsed time indicator attribute presents the total time in years,
days, hours, minutes and seconds since the last system restart. The system can restart for
several reasons, for example commanded reboot from the system reboot web page, or a
power cycle of the equipment.
Ethernet Link Status: 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.
113
8 Web Page Reference
Ethernet Speed and Duplex: The negotiated speed and duplex setting of the Ethernet
interface. The speed setting is specified in Mbps. Full Duplex data transmission means that
data can be transmitted in both directions on a signal carrier at the same time. For example,
on a local area network with a technology that has full duplex transmission; one workstation
can be sending data on the line while another workstation is receiving data. Half Duplex data
transmission means that data can be transmitted in both directions on a signal carrier, but not
at the same time. For example, on a local area network using a technology that has half
duplex transmission, one workstation can send data on the line and then immediately receive
data on the line from the same direction in which data was just transmitted.
Remote IP Address: Hyperlink to the other side of the Link. The IP address of the peer link is
displayed if the Link is UP, otherwise “unavailable” is displayed.
Channel A: The status of telecom interface A.
Channel B: The status of telecom interface B.
Refresh Page Period: The Status page refreshes automatically according to the setting
entered here (in seconds). This attribute is only displayed when the user is logged on as
System Administrator.
Wireless Link Status: As the attribute name suggests it displays the current status of the
wireless link. A state of ‘Up’ on a green background indicates that a point-to-point link is
established. A state of ‘Down’ on a red background indicates that the wireless link is not
established.
Maximum Transmit Power: The maximum transmit power that the local wireless unit is
permitted to use to sustain a link.
Remote Maximum Transmit Power: The maximum transmit power that the remote wireless
unit is permitted to use to sustain a link.
Transmit Power: Transmit power histogram
11
is expressed in dBm and presented as: max,
mean, min, and latest. The max, min and latest are true instantaneous measurements; the
mean is the mean of a set of one second means.
11
An histogram is calculated over a one hour period. If the equipment has been running for less than one hour
then the histogram is calculated over the current elapsed time.
The data used to compute the histogram statistics can be downloaded in an ASCII comma separated value
(CSV) format via the diagnostics CSV Download page, see Section 8.3.12.2 “Diagnostics Download”.
114
8 Web Page Reference
Receive Power: Receive power histogram is expressed in dBm and presented as: max,
mean, min, and latest. The max, min and latest are true instantaneous measurements; the
mean is the mean of a set of one second means. See footnote 11.
Vector Error: The vector error measurement compares the received signal’s In phase /
Quadrature (IQ) modulation characteristics to an ideal signal to determine the composite error
vector magnitude. The results are stored in an histogram and expressed in dB and presented
as: max, mean, min and latest. The max, min and latest are true instantaneous
measurements; the mean is the mean of a set of one second means. The expected range for
Vector Error would be approximately -2dB (NLOS link operating at sensitivity limit on BPSK
0.67) to –33dB (short LOS link running 256 QAM 0.83). See footnote 11.
Link Loss: The link loss is the total attenuation of the wireless signal between the two

System Configuration
The configuration of the 600 Series Bridge is organized into three sections:
•
General configuration
•
LAN configuration
•
Telecoms Configuration
•
Save and Restore
The general configuration allows modification of high level administrative (descriptive)
attributes and high level wireless configuration.
The LAN configuration sub menu allows the system administrator to modify the Ethernet and
IP configuration of the 600 Series Bridge.
The telecoms submenu displays the current status of the telecoms interface and allows the
configuration of interface loopbacks.
The save and restore submenu allows the system administrator to backup and restore the
bridge configuration. It is recommended after a unit has been successfully installed; a copy of
the active configuration is taken and archived by the system administrator.
8.3.1.1
General Configuration Page
The general configuration page (Figure 48) is used by the system administrator to configure
the 600 Series Bridge’s high level administrative (descriptive) attributes and high level
wireless configuration.
Figure 48 - System Configuration Page
118
8 Web Page Reference
While the majority of the system configuration is entered during installation and should never
require changing, this page offers the system administrator the ability to change the basic
system parameters for both the wireless and Ethernet components.
Link Name: User defined identity for the unit (max 63 characters).
Link Location: Can be used as a generic scratch pad to describe the location of the
equipment.
Master Slave Mode and Link Mode Optimization: Current settings are displayed and can
be modified using the Installation Wizard pages 8.3.4 “Install Pages”.
Max Receive Modulation Mode: This is the maximum mode the unit will use as its adaptive
modulation. By default the Max Receive Modulation Mode is the highest mode available.
For minimum error rates on TDM links the user should set the maximum modulation mode to
64QAM 0.75 at both ends of the link.
Ethernet Capped Max Wireless Speed: When enabled this option will cap the wireless
speed to a mode that the connected Ethernet connection can sustain.
Maximum Transmit Power: This specifies the maximum transmit power in dBm of the
system. It is country dependent and although the user can change this in 1dB steps, it will be
14
limited to that country’s regulations .
NOTE: Why Reduce Transmit Power? If the link losses are low and the link data rate and
availability targets are being easily achieved, the transmitted power level may be reduced
with a consequent benefit to other users of the band, such as fixed satellite links.
14
In the UK there is a legal requirement to provide a minimum of 19dB of transmit power control range. When
the equipment is operating with a UK Licence Key, an additional facility is provided on the configuration page that
allows the transmitted power to be reduced by 19dB compared to the maximum allowed with a simple single step
control.
119
8 Web Page Reference
8.3.1.2
LAN Configuration Page
The LAN configuration page (Figure 49) is used by the system administrator to configure the
600 Series Bridge’s LAN interface.
Figure 49 - 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.
120
8 Web Page Reference
Gateway IP Address: The IP address of a computer / router on the current network that acts
as a gateway.
VLAN High Priority Traffic Threshold: All packets with an 802.1P priority tag greater than
or equal to the indicated value will be treated as a high priority packet for transmission over
the wireless link.
Use VLAN For Management Interfaces: This controls use of VLAN tags at the management
interfaces (WWW/SNMP/SMTP/SNTP). See Section 8.3.1.3 “LAN Configuration Page – Use
VLAN For Management Interfaces”.
Ethernet Auto Negotiation This enables the Ethernet configuration to be forced rather than
auto negotiated.
CAUTION: The configuration should only be forced if you are having problems with auto
negotiation. You must ensure that you configure both this unit and the Ethernet port to which
it is connected identically. If you force a fixed Ethernet Configuration on the 600 Series bridge
then you MUST also force the same fixed configuration on the equipment to which it is
connected. If you fail to force the configuration of the connected equipment, its automatic
configuration mechanisms will normally cause a duplex mismatch, and you will receive greatly
reduced throughput!
When Ethernet Auto Negotiation is Disabled the format of the LAN configuration page will
change see Section 8.3.1.4 “LAN Configuration Page – Manual Ethernet Configuration”.
Auto Neg Advertisement: This controls the rates that the auto negotiation mechanism will
advertise as available.
CAUTION: Over the air throughput will be capped to the rate of the Ethernet interface at the
receiving end of the link.
Ethernet Auto Mdix: This enables/disables the Auto Medium Dependent Interface
(MDI)/Medium Dependent Interface Crossover (MDIX) capability. Default is “Enabled”.
Drop Ethernet Link On Wireless Link Down: When this option is enabled the Ethernet link
is momentarily dropped when the wireless link goes down. This feature is used to indicate to
the connected network equipment that this Ethernet link is no longer available, thus causing
STP (Spanning Tree Protocol) to re-route packets through an alternative link.
121
8 Web Page Reference
Local Packet Filtering: When Local Packet Filtering is “Enabled”, the bridge learns the
source MAC addresses of devices transmitting Ethernet packets on the local Ethernet
network, and only bridges packets to the remote unit if the destination MAC address has not
been learned as a 'local' device. When Local Packet Filtering is ‘Disabled’ the bridge does
not learn the source MAC addresses of devices transmitting Ethernet packets on the local
Ethernet network, and bridges ALL Ethernet packets received to the remote unit.
Local
Packet Filtering should be disabled when external Ethernet switching hardware or a router is
present. The default setting for Local Packet Filtering is disabled.
All of the above attributes are non-volatile, once set they will be used by the unit even after a
power on reboot. A number of attributes, such as IP Address, Subnet Mask and Gateway IP
Address and VLAN settings will require a reboot before they are used. If any of these
attributes are changed a reboot screen appears asking the user to verify the reboot (Figure
50 or Figure 51).
Figure 50 - Configuration Reboot Page
Figure 51 - Configuration Reboot Page - Ethernet Auto Negotiation Disabled
This will be followed by a pop-up dialogue box asking to confirm the action.
122

NOTE: At this point you will lose connection to the unit. If you have just changed the IP
Address you now have to reconnect to the unit using the address just set.
8.3.1.3
LAN Configuration Page – Use VLAN For Management Interfaces
The layout of the LAN Configuration page changes if this attribute is enabled in order to allow
the VLAN VID and VLAN Priority to be set, see Figure 52. The VLAN settings are applied only
after the unit is rebooted.
CAUTION: You must ensure that you can access the VLAN which you configure here,
otherwise you will be unable to access the unit following the next reboot.
CAUTION: The PTP 600 management function is only compatible with single VLAN tagged
packets. Any management packet with two or more packets will be ignored.
Figure 52 - VLAN Configuration Fields
123
8 Web Page Reference
Use VLAN For Management Interfaces: This control can be configured with one of the
following three values:
•
No VLAN Tagging
•
IEEE 802.1Q Tagged (C-Tag, Type 8100)
•
IEEE 802.1ad Tagged (S-Tag or B-Tag, Type 88a8)
VLAN Management VID: This 802.1Q or 802.1ad VLAN ID (VID) will be included in packets
generated by the management interfaces. Valid settings are in the range 0 to 4094.
VLAN Management Priority: This 802.1Q or 802.1ad VLAN Priority will be included in
packets generated by the management interfaces. Valid settings are in the range 0 to 7.
VLAN Management VID Validation: If enabled, the management interfaces will only respond
to Ethernet packets tagged with the configured Management VID; otherwise packets with any
VID will be accepted.

CAUTION: Over the air throughput will be capped to the rate of the Ethernet interface at the
receiving end of the link.
8.3.1.5
Save and Restore Configuration File
The save and restore feature of a PTP 600 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 600 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.
8.3.1.5.1
Save Configuration File
To save the configuration file click on the ‘Save Configuration File’ button (Figure 54) and
save the configuration file (.cfg) to the hard drive of your computer

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.

CAUTION: The configuration file is currently restricted to a single software version and can
only be restored into a wireless unit operating the software version indicated in the
configuration file header.
8.3.1.5.2
Restore Configuration File
The configuration file can also be used when swapping out a faulty wireless unit. If one of the
wireless units is replaced on a wireless link a configuration file captured from the faulty unit
can be uploaded into the new unit to speed up replacement.
NOTE: The licence key of the faulty unit should be setup on the replacement unit before the
configuration file is loaded. This can be obtained either from the Quick Start Guide supplied
with the faulty wireless unit or directly from Motorola. The target MAC address at the other
end needs to be changed to ensure that it is using the MAC address of the replaced unit.
The restoration of configuration files can be performed using the Restore configuration tool.
Using the browser button to locate the configuration file you wish to restore then click the
‘Restore Configuration File and Reboot’ button (Figure 57). The user will then be prompted to
confirm the action (Figure 58)
Figure 57 - Restore Configuration File Pop Up Screen

Figure 58 - Reset Configuration and Reboot Confirmation Pop-up
On confirmation the PTP 600 Series Bridge will:
•
Upload the configuration file
•
Perform data integrity checking
•
Erase previous configuration
•
Apply the new configuration
•
Restart
After the unit has restarted the entire configuration from the configuration file will now be
active. Note: The IP address of the unit may have also been changed. The user can check
the new IP address by reading the header of the configuration file, Figure 56.

Telecoms Configuration Page
The Telecoms page is only available when the Telecoms Interface has been set to either T1
or E1 in the Installation Wizard.
It displays the interface setting and line code for the available telecoms channels. The PTP
600 Series Bridge is able to support two T1 or E1 channels. However, in the “Lite”
configuration one of these channels is disabled. The channels are referred to as "Channel A"
and "Channel B".
The "Channel B" configuration and controls will be displayed only when the second channel is
enabled.
Figure 59 - Telecoms Data Entry
Telecoms Interface: May be either T1, E1 reflecting the Installation Wizard setting.
Line Code: Displays the Line Code setting for each channel. The Line Code configuration
must match the configuration of the connected equipment and may be set using the
Installation Wizard.
129
8 Web Page Reference
Cable Length: The Cable Length setting is applicable in T1 mode only and shows the cable
length specified in the installation wizard.
Loopback: Allows the T1 or E1 data stream to be looped back at the copper or wireless
interface. During normal operation the loopback must be set to "None".
It may be helpful during installation to test the telecoms links by performing loopback
connections.
A "Copper" loopback connects the received data on a given telecoms interface to the
Transmit. A "Copper" loopback may be used, in conjunction with an appropriate test unit, to
confirm that the correct connections have been made to the ODU.
A "Wireless" loopback sends the telecoms data received across the wireless link back across
the link on the same Telecom channel. The link may be checked using, for example, a Bit
Error Rate Tester to ensure that no errors are detected.
A typical T1 or E1 installation might include a "Copper" loopback on the local unit followed by
a "Wireless" loopback on the remote unit.
It is important to remove all loopbacks on channels for normal operation.
Alarms on the Home Page indicate the presence of loopbacks on either channel.

CAUTION: The factory default configuration is limited in range to 40 Km (25 miles). If you
wish to install a wireless link with a range of > 40 Km (> 25 miles) and < 200 Km (< 124 miles)
or < 5 Km (< 3 miles) you must follow the ‘Manually Configuring The Wireless Units’ in
Section 8.3.4.1.
138
8 Web Page Reference
CAUTION: The factory default configuration is set to Region 1. Region 1 allows the 600
Series bridge a maximum transmit power of 25 dBm. If the local regulatory regime limits the
maximum transmit power (EIRP) to less than 25 dBm you should obtain a new license key
containing the correct region code from your local distributor or direct from Motorola.
Alternatively in the short term, you should reduce the maximum transmit power by following
the procedures in ‘Manually Configuring The Wireless Units’ in Section 8.3.4.1.
8.3.4.1
Manually Configuring The Wireless Units
If the installer / system administrator wishes, they may modify the default installation
configuration. If only the IP addresses (network configuration) are incorrect it is recommended
that the values are changed via the configuration menu (Section 8.3.1.2 “LAN Configuration
Page”).
CAUTION: If any other parameters (for example Region Code) require modification, then it is
recommended that the system administrator use the Installation Wizard.
A detailed description of the Installation Wizard follows:
The 600 Series bridge operational software requires a license key to enable the wireless
bridging capability and programs region code specific parameters in to the unit.
Figure 62 - License Key Data Entry
139
8 Web Page Reference
A license key is programmed into each unit during production and can be found written on the
Configuration Data Summary Label which is attached to the Quick Install Guide. If
subsequently the license key has been mislaid, replacement keys can be applied for online or
via your distributor.
If a valid license key is not detected in the unit’s non-volatile memory then the user is
prompted to enter a valid key. It should be noted that 600 Series bridge units are shipped as
link pairs and, as such, valid license keys are entered during the production process. To enter
a license key simply type or paste the license key into the data entry box (Figure 62) and click
the ‘validate license key’ button.
8.3.4.2
Internet Protocol Configuration
Step 1 of the installation wizard requires the installer to enter the Internet Protocol (IP)
configuration.

Telecoms Channel Selection: This controls the selection of the telecoms interface standard
supported options or T1 and E1.
Channel A Line Code: The line code setting of the telecoms interface. This must match the
setting of the device connected to this interface.
Channel B Line Code: The line code setting of the telecoms interface. This must match the
setting of the device connected to this interface.
Cable Length: This field is applicable to the T1 operating mode only. It configures the T1
transceiver to output a signal suitable for driving a cable of the specified length. This should
be set to reflect the length of cable between the wireless unit and the connected equipment.

Target MAC Address: It is the MAC Address of the peer unit that will be at the other end of
the wireless link. This is used by the system to ensure the unit establishes a wireless link to
the correct peer.
The MAC Address can be found embedded within the serial number of the unit. The last six
characters of the serial number are the last three bytes of the unit’s MAC address.
NOTE: A PTP 600 Series system is shipped as a pair of units with pre-loaded correct MAC
addresses. Target MAC addresses will only need to be entered if an existing unit has to be
replaced in the field or the units configuration has been erased.
Master Slave Mode: At this point it is necessary to decide which end will designate a Master.
The Master unit is the controlling unit with respect to the point-to-point link and its
maintenance. The master transmits until the link is made, while the Slave listens for its peer
and only transmits when the peer has been identified.

Link Mode Optimization: Optimizes the link behavior according to the type of traffic that will
be bridged. There are two modes to choose from: IP and TDM.
In IP Mode, the PTP 600 product runs an Adaptive TDD scheme. Basically an unloaded link
runs 10:10 mode (10 OFDM bursts alternately in each direction). A sustained traffic load in
one direction for example may cause a threshold to be reached where the TDD mode
automatically adapts to say 20:10. If the load continues to increase, then the TDD structure
may adapt even further through 30:10 to 40:10. This is a state of maximum link asymmetry
(40 OFDM bursts in one direction compared with 10 in the other). If the load increases in
BOTH directions, then the TDD structure can adapt from 10:10, through 20:20, 30:30 and
finally 40:40. This is a state of maximum aggregate throughput. So if three out of these
combinations are considered; 10:10, 40:10 and 40:40 they would give the following
characteristics:
•
10:10 equal performance in each direction, lowest aggregate throughput and lowest
Latency.
•
40:10 achieves maximum one way throughput performance, to the detriment of both
latency and throughput in the opposite direction.
•
40:40 Maximum link aggregate rate, balanced performance in each direction, higher
latency.
NOTE: There is an engineering trade-off between the flexibility of ATDD and Latency as
follows: When the TDD structure changes, there will be a short term impact on Latency for a
few Frames. This would not affect the steady state long term average latency, but could be
recorded as a Maximum latency. This affect may be amplified for short Latency tests or if the
traffic loading is oscillating either side of a boundary condition. As the TDD burst length
increases, Traffic in each direction will have to wait longer before a Transmit window is
available, but more data can be sent during the burst. There is an impact on latency but it
varies depending upon installation range, Frame size and modulation mode.

In TDM mode, two major differences in link behavior occur compared with IP mode. First the
TDD structure is fixed symmetrically. Either 10:10, 20:20, 30:30 or 40:40 based upon the
installed range, as shown in Table 27.

Secondly, the point at which a modulation mode changes for given RF conditions is more
conservative. In practice, this means that the link will typically stay in a lower modulation
mode, but with increased tolerance to RF variability.
Depending upon the link characteristic that the customer requires, this may very well be the
best choice. It increases consistency of link performance and equality in each direction as a
trade-off against maximum throughput.
TDD Synchronization Mode: Enables the TDD Synchronization feature (see Section 5.11
“Time Division Duplex (TDD) Synchronization” for basic description and Section 14 “TDD
Synchronization Configuration and Installation Guide” for installation and configuration
details).
Tx Max Power: This attribute controls the maximum transmit power the unit is permitted to
use when installing and executing the wireless link. The maximum setting for a particular
region or country is controlled by the License Key.

Ranging Mode: During installation, the wireless units perform “Automatic Ranging”. The
ranging mode allows the installer to control the behavior of the system’s automatic ranging
algorithms. The default value is 0 to 40 km
18
(0 to 25 miles). If the installer is required to
install a link of greater than 40 km (25 miles) then the ranging mode attribute MUST be
configured to ‘0 to 100km’ (0 to 62 miles) or ‘0 to 200km’ (0 to 124 miles) mode depending on
the range of the link.
Target Range: Installers that know the range between the two wireless units to within ± 1 km
can use the target range mode. The main advantage of the target range mode is that it
reduces the time taken by the units to range. To use the target range mode the installer
MUST select Target Range as the ranging mode and enter the approximate range in km in
the Target range data entry field at both ends of the link.
Platform Variant: Chooses between an integrated unit or a connectorized unit that requires
an external antenna.
Frequency Band: This is for the PTP 25600 product variant which operates in one of three
bands as described in Section 5.4 “Variable Channel Bandwidth Operation”.
Channel Bandwidth: Users can choose a variable channel bandwidth for the available
spectrum. Values of 5 MHz, 10 MHz, 15 MHz and 30 MHz can be selected.
Link Symmetry: (Master only) Values of Adaptive, 2:1, 1:1 and 1:2 can be selected. In fixed
symmetric mode, the master spends an equal amount of time transmitting and receiving
whereas in fixed asymmetric mode, the master transmit and receive times have a fixed ratio.
NOTE: (a) "Adaptive" is not supported in regions where radar avoidance is in use, (b)
"Adaptive" is not supported when link optimization is set to "TDM", (c) "Adaptive" is not
supported in 5 MHz channel bandwidth, (d) "2:1" and "1:2" are not supported in 5 MHz
channel bandwidth.

Spectrum Management Control: Is used to configure the PTP 600 Series Bridge’s
Spectrum Management features, see Section 8.3.7 “Spectrum Management” for more details.
i-DFS is the abbreviation for intelligent Dynamic Frequency Selection. This feature continually
monitors the spectrum looking for the channel with the lowest level of on channel and cochannel interference. Fixed frequency mode allows the installer to fix transmit and receive
frequencies on the units. The frequencies may be configured symmetrically or
asymmetrically. Only 30MHz channels are available in regions that mandate DFS (Radar
Detection), and the Spectrum Management Control may not be available because the
regulations for some regions force DFS, others force fixed frequency (for example 2.5 GHz).
Lower Center Frequency: The software for the PTP 600 Series Bridge allows a user to
optionally adjust the channel center frequencies. Changing the Lower Center Frequency
attribute causes all channel center frequencies to be offset. It effectively slides the
channelization up or down. See Sections 5.5 or 5.6, 5.9 and 5.10 depending on the frequency
variant.
CAUTION: The lower center frequency attribute must be configured to the same value for
both the master and slave. Failure to do so will cause the wireless link to fail reestablishment.
The only way to recover from this situation is to modify the Lower Center Frequency attribute
so that they are identical on both the master and slave unit.
Default Raster: If this is set to “On”, the list of options presented in the fixed Tx frequency
box is limited by the default raster.
Fixed Tx Frequency, Fixed Rx Frequency: The software for the PTP 600 Series Bridge
allows a user to optionally fix the Transmit and the Receive frequencies for a wireless link.
The settings must be compatible at each end of the link. Once configured the spectrum
management software will not attempt to move the wireless link to a channel with lower co or
adjacent channel interference. Therefore this mode of operation is only recommended for
deployments where the installer has a good understanding of the prevailing interference
environment. Figure 68 shows a sample fixed frequency configuration for a 30 MHz channel
bandwidth. In the example the lower center frequency is set to its default values and the
Fixed Transmit Frequency is set to 5742 MHz and the Fixed Receive Frequency is set to
5742 MHz. Care must be taken when configuring the Fixed Transmit and Receive
Frequencies to ensure that both frequencies are on the same 10 MHz channel raster as the
Lower Center Frequency. For example both the Fixed Transmit and Receive Frequencies
must be a multiple of 10 MHz from the Lower Center Frequency (5752 = 5742 + 10 MHz) and
(5782 = 5742 + 10 MHz × 3).
