General
Changes or modifications not expressly approved by Motorola could void the user’s authority to
operate the system.
NOTE: This system has achieved Type Approval in various countries around the world. This means
that the system has been tested against various local technical regulations and found to comply. The
frequency band in which the system operates is ‘unlicensed’ (except from the 4.9 Ghz product) and
the system can be used provided it does not cause interference. Further, it is not guaranteed
protection against interference from other products and installations.

The system has basically been shown to comply with the limits for emitted spurious radiation for a
1
Class B digital device
, pursuant to Part 15 of the FCC Rules in the USA as well as comparable
regulations in other countries. This equipment generates uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur in a particular
installation.
If this equipment does cause harmful interference to other equipment, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
• Reorient or relocate the Outdoor Unit (ODU).
• Increase the separation between the equipment and ODU.
• Connect the equipment into a power outlet on a circuit different from that to which the
receiver is connected.
Consult your installer or supplier for help.
Deployment and Operation
The Radio Regulations of various countries’ limits constrain the operation of radio products generally.
In particular the local regulator may limit the amount of conducted or radiated transmitter power and
may require registration of the radio link.
The power transmitted by the PTP 400 Series is controlled by the use of Region-specific License
Keys.
The following examples show how the regulatory limits apply in some specific countries at the current
time. Operators should note that regulations are subject to change.
Contact your supplier/installer to ensure that your product is set for the correct License Key for your
Country/Region and to ensure that you have fulfilled all the local regulatory requirements, especially if
you are intending to use a link with external antennas. Footnotes to the table below indicate countries
where registration of the link is currently mandatory.

2 Avoiding Hazards
2.1 Preventing Overexposure to RF Energy
Caution To protect from overexposure to RF energy, install the radios for the 400 family of
wireless solutions so as to provide and maintain the minimum separation distances from all
persons as shown in
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.
2.1.1 Calculations for Separation Distances and Power Compliance Margins
Note These are conservative distances that include compliance margins. In the case of the
reflector, the distance is even more conservative because the equation used models the
reflector as a point source and ignores its physical dimensions.
Limits and guidelines for RF exposure come from:
• US FCC limits for the general population. See the FCC web site at
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
Table 3.
http://www.fcc.gov,
OET Bulletin 65.
• Health Canada limits for the general population. See the Health Canada web site at
http://www.hc-sc.gc.ca/rpb and Safety Code 6.
• ICNIRP (International Commission on Non-Ionizing Radiation Protection) guidelines for
the general public. See the ICNIRP web site at

Page 60
7.7.8 Mounting the PTP 400 Series Bridge PIDU Plus
Motorola recommends that you mount the PIDU Plus on a wall or other suitable mounting
surface. This prevents the unit from being knocked or kicked and can help maintain link
availability. Ensure that the reset switch can be accessed when mounting the unit.
Step 1: Fix the PIDU Plus to the wall using the lugs provided.
Step 2: Make connections as per Section
7.7.6
WARNING: The PIDU Plus is not waterproof and should be mounted away from sources of
moisture. If mounted outdoors, the unit should be mounted in a rain proof enclosure,
preferably ventilated.
It is also recommended that you fit a drip loop on the PIDU Plus to ODU cable to ensure that
any moisture that runs down the cable into the cabinet or enclosure cannot enter the PIDU
Plus. As shown in
Figure 23. The network connection and mains cable should be treated in
the same way if there is a risk that they can carry moisture to the PIDU Plus.

Figure 23 - PTP 400 Series Bridge PIDU Plus Drip Loop Configuration
WARNING: It is possible for moisture to enter the cable due to damage to the outer protective
layer. This moisture can track down the inside of the cable, filling up the drip loop and
eventually finding its way into the PIDU Plus. To protect against this the outer protective layer
of the cable can be opened up at the bottom of the drip loop to allow this moisture to escape.
WARNING: Some network operators employ gel filled cables to get around the problem of
moisture ingress and transmission. The PTP 400 Series Bridge has NOT been tested using
these cables. Use of gel filled cables may affect the performance of PTP 400 Series Bridges.

7.7.9 Powering Up
The PTP 400 Series Bridge is supplied as a pair of matched Master/Slave units. The Master
unit to be configured can now be powered up and accessed using the default URL
http://169.254.1.2/ ; the Slave unit can be accessed using http://169.254.1.1/
Prior to powering up the PTP 400 Series Bridge, a computer with web browsing capabilities
should be configured with an IP address of 169.254.n.n and subnet mask of 255.255.0.0
where n is any value between 1 and 254 but excluding 1.1 or 1.2. If the default addresses of
the unit 169.254.1.1/2 clashes with an address you are already using on your LAN, or you are
not sure, you should set up an isolated LAN. As the LAN connection presented at the PIDU
Plus has a default configuration as a hub/switch (and auto-sensing MDI/MDIX cross over is
employed) connection can be made directly to the computer using a standard CAT 5 patch
cable.
Before physical installation takes place the units to be installed should be set up as described
in the section
address to one that is in the desired address range and set each unit up with the MAC
address of its peer unit ready to establish a radio link. It is recommended that this procedure
be carried out on the bench before physical installation commences. Providing it is safe to do
so the installer should take the process to the point where a radio link is established before
proceeding to the installation site.
NOTE: It is possible that some units may not be accessed using the above default URL. This
is because these units may have been previously configured with IP addresses 10.10.10.10
(Slave) and 10.10.10.11 (Master). Therefore, users must use the URL
and/or URL
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.
8.3.5. This process will give the installer the opportunity to set the unit’s IP
http://10.10.10.10/
http://10.10.10.11/ to configure the units. Please ensure that a computer with web

The term ‘wanted signal’ refers to that of the peer unit being installed.
In each of the states detailed above the unit should be aligned to give the highest pitch tone.
It should be noted that if, when in the Synchronized or Registered state the tone varies wildly,
you may be suffering from interference or a fast fading link. Installing in this situation may not
give a reliable link. The cause of the problem should be investigated.
For the ease of alignment both Master and Slave units use the install tones in the same way
but with some small behavioral differences. This allows the installer to install the Slave unit
first and carry out the initial alignment with the Master unit if desired. However due to the
Behavioral differences of Master and Slave units it is recommended that the Master unit is
installed first and the initial alignment carried out at the Slave unit.
13
The pitch of the alignment tone is proportional to the power of the received wireless signals. The
best results are usually achieved by making small incremental movement in angular alignment.
61
Page 64
The following behavior should be noted:
When first started up and from time to time the Master unit will carry out a band scan to
determine which channels are not in use. During this time, between 10 and 15 seconds, the
Master unit will not transmit and as a consequence of this neither will the Slave unit. During
this time the installation tone on the master unit will drop back to the band scan state and the
Slave unit will drop back to Scanning state with the pitch of the tone set be the background
noise level. Alignment of the unit should cease during this time.
The master unit can take between 30 seconds in 0-5km (0-3 miles) mode to 300 seconds in
14
0-200km (0-124 miles) mode to determine the range of the link being installed
. The Master
unit will remain in the Scanning state until the range of the link has been established. The
Master unit will only move to the Synchronized state when the range of the link has been
established.
If at the end of the ranging period the ‘Registered’ state is not achieved due to interference or
other reasons, the Master unit will retry twice more on the same channel before moving to
another available channel. Should this occur it might take a number of minutes to establish a
link in the ‘Registered’ state.
The Slave unit does not have a ranging process. The slave unit will change to the
Synchronized state as soon as the wanted signal is demodulated.
When the alignment process is complete the installer MUST REMEMBER TO DISARM BOTH
UNITS in the link as described in section
8.3.5. This is necessary for the following:
• Turn off audible alignment aid.
• Enable Adaptive Modulation
• Fully enable Dynamic Frequency Selection
• Clear unwanted installation information from the various systems statistics
• Store the link range for fast link acquisition on link drop
• Enable Higher Data Rates
14
If the unit is operating where mandatory radar avoidance algorithms are implemented the ranging
behavior for the 400 Series Bridge may be affected. The Master has to monitor the initially chosen
channel for 60 seconds to make sure it is clear of radar signals before transmitting. If radar is
detected during any of the installation phases a further compulsory 60 seconds channel scan will take
place as the master unit attempts to locate a new channel that is free of radar interference.

The units will automatically disarm after 24 hours.

The web user interface has three main sections. The home page presents to the operator a
high level summary of the PTP 400 Series Bridge point-to-point wireless link. The status page
presents a more detailed set of system parameters describing the performance of the
wireless link together with other key system performance metrics. The final section is the
system administrator section. This section is password protected and allows the system
administrator to perform all the day-to-day administrative procedures, e.g. software upgrades
and configuration changes.
The following subsections give a detailed usage guide for all the web user interfaces.

8.1 Home Page – PTP 400 Series Bridge
The home page for the PTP 400 Series Bridge has been designed to display a high level
summary of the status of the wireless link and associated equipment. The home page (
) normally displays four key system attributes:
25
Wireless Link Status: The Wireless Link Status attribute as the name suggests displays the
current status of the wireless link. A state of ‘Up’ on a green background indicates that a
point-to-point link is established. A state of ‘Down’ on a red background indicates that the
wireless link is not established. If the link is down for an unknown reason the system
administrator should first consult the status web page for a more detailed summary of up to
date system diagnostics.
Link Name: The link name attribute is a name and/or handle allocated by the system
administrator to aid the identification of the unit, network or building.
Figure
Figure 25 - PTP 400 Series Bridge Home Page
Elapsed Time Indicator: The elapsed time indicator attribute presents the total time in days,
hours, minutes and seconds since the last system restart. The system can restart for several
reasons, e.g. commanded reboot from the system reboot webpage, or a power cycle of the
equipment.
System Clock:If the SNTP (Simple Network Time Protocol) (see section

triangle will cause the web page to jump back to the system home page.
sample alarm screen.
Figure 26 shows a
Figure 26 - Alarm Warning Triangle
The following major system alarms are defined:
Install Arm State: The Install Arm State alarm is displayed. This alarm warns when a
wireless unit is in installation mode. After installation the wireless unit should be disarmed.
This will increase the wireless link’s data-carrying capacity and stop the installation tone
generator. The wireless link is disarmed from the ‘Installation Wizard’ see section
8.3.5.
66
Page 69
Install Status: If any errors are detected during the installation process, the unit will
automatically raise an audible alarm. The install status alarm will be raised with an
appropriate reason code, e.g. the alarm will be raised if an incorrect target MAC address is
specified for the peer PTP 400 Series Bridge wireless unit.
ARQ Is Not Configured: ARQ must be enabled on both ends of the Point-to-Point link. This
error message is generated if there is a mismatch in the ARQ settings between both ends of
the link.
Encryption Is Not Configured On Both Units: Encryption must be enabled on both ends of
the Point-to-Point link before the over-the-air packets can be successfully decrypted. This
error message is generated if encryption is not configured on both units.
Ethernet Link Status: If there are any problems with the Ethernet interface this alarm will be
asserted. This alarm will most likely be seen if the unit has not got an Ethernet cable plugged
into its Ethernet socket.
Master And Slave Have Incompatible Region Codes: The PTP 400 Series Bridge uses
region codes to comply with local regulatory requirements governing the transmission of
wireless signals. Region codes can only be changed by obtaining a new PTP 400 Series
Bridge license key. If this alarm is encountered the appropriate license keys from the country
of operation should be obtained from your distributor. Applying license keys containing the
same region codes to both ends of the link will remove the alarm.
Spectrum Management Channel Warning: The alarm warns a user when the intelligent
spectrum management feature can't find a suitable wireless channel. This alarm occurs when
the signal assessment features of the PTP 400 Series Bridge can’t find a channel to operate
on.
Ethernet Configuration Mismatch: The detection of Ethernet fragments (runt packets) when
the link is in full duplex is an indication of an auto-negotiation or forced configuration
mismatch.
Wireless Link Disabled Warning: Wireless traffic has been disabled via the SNMP
ifAdminStatus attribute.
SNTP No Sync Warning: This warning indicates that SNTP has been enabled but that the
unit is unable to synchronize with the specified SNTP server. Section
8.3.13 explains how to
configure SNTP.

8.2 System Status Page
The status page has been designed to give the system administrator a detailed view of the
operation of the PTP 400 Series Bridge from both the wireless and network perspectives.
The page is subdivided into three main categories Equipment, Wireless and Ethernet/Internet.
The ‘Equipment’ section contains the entire unit’s inventory and identification information. The
‘Wireless’ section presents the key wireless metrics displayed as a series of measurements
and histograms. The ‘Ethernet/Internet’ section describes the unit’s network identity and
connectivity.
The status page can be configured to refresh itself at an operator defined rate (if the user is
logged in as system administrator). The refresh period defaults to 3600 seconds and can
easily be changed to refresh at any period between 2 seconds and 3600 seconds. Pressing
the ‘Update Page Refresh Period’ button causes a new page refresh period to be adopted by
the system. The page refresh mechanism uses a HTML Meta refresh command. Therefore
the refresh is always initiated by the local browser and not by the PTP 400 Series Bridge at
this interval.
Figure 27 - Status Page
68
Page 71
The two PTP 400 Series Bridges are arranged in a master and slave relationship. The roles
of the units in this relationship are displayed in the page title. The master unit will always have
the title ‘- Master’, and the slave will always have the ‘- Slave’ appended to the ‘Systems
Status’ page title.
The following section details all the attributes displayed on the status page
:
Link Name: The link name is allocated by the system administrator and is used to identify the
equipment on the network. The link name attribute is to a maximum size of 63 ASCII
characters.
Link Location: The link location is allocated by the system administrator and can be used as
a generic scratch pad to describe the location of the equipment or any other equipment
related notes. The link location attribute is limited to a maximum size of 63 ASCII characters.
Software Version: The attribute describes the version of software installed on the
equipment. The format of the attributes is FFPP-XX-YY where FF is the frequency variant
(4.9, 5.8 or 5.4 GHz), PP is the product variant, XX is the major release version and YY is the
minor release version.
Hardware Version: The hardware version attribute contains all the combined hardware
version information. The attribute is formatted as DX.-RYY-Z where DXX contain the version
of the digital card, RYY contains the version of the RF (radio frequency) card and Z describes
the antenna type which can be I (integrated) or C (connectorized).
Region Code: The region code is used by the system to constrain the wireless to operate
within the regulatory regime of the particular country. The region code is encoded in the
product license key. If the operator wishes to change the region code, a new license key must
be obtained from Motorola or the local distributor / system integrator.
Elapsed Time Indicator: The elapsed time indicator attribute presents the total time in years,
days, hours, minutes and seconds since the last system restart. The system can restart for
several reasons, e.g. commanded reboot from the system reboot web page, or a power cycle
of the equipment.
Ethernet Link Status: Current status of the Ethernet link. A state of ‘Up’ with a green
background indicates that an Ethernet link is established. A state of ‘Down’ with a red
background indicates that the Ethernet link is not established.
Ethernet Speed: The negotiated speed of the Ethernet interface specified in Mbps.
Ethernet Duplex: The negotiated duplex of the Ethernet interface.
69
Page 72
Full Duplex: Full Duplex data transmission means that data can be transmitted in both
directions on a signal carrier at the same time. For example, on a local area network with a
technology that has full duplex transmission; one workstation can be sending data on the line
while another workstation is receiving data.
Half Duplex: Half Duplex data transmission means that data can be transmitted in both
directions on a signal carrier, but not at the same time. For example, on a local area network
using a technology that has half duplex transmission, one workstation can send data on the
line and then immediately receive data on the line from the same direction in which data was
just transmitted.
MAC Address: The Medium Access Control Layer (MAC) address is used to uniquely
identify the equipment on an Ethernet network.
IP Address: Internet Protocol (IP) address. This address is used by the family of Internet
protocols to uniquely this identify the unit on a network
Subnet Mask: A subnet allows the flow of network traffic between hosts to be segregated
based on a network configuration. By organizing hosts into logical groups, subnetting can
improve network security and performance.
Gateway IP Address: The IP address of a computer on the current network that acts as a
gateway. A gateway acts as an entrance / exit to packets from / to other networks.
Wireless Link Status: As the attribute name suggests, this displays the current status of the
wireless link. A state of ‘Up’ on a green background indicates that a Point-to-Point link is
established. A state of ‘Down’ on a red background indicates that the wireless link is not
established. If the link is down for an unknown reason the system administrator should first
consult the status webpage for a more detailed summary of the prevailing system diagnostics.
Target Receive Modulation Mode: The target modulation mode is used by the wireless
subsystem to control the adaptive modulation algorithm. The mode is used by the PTP 400
Series Bridge as an upper limit. The system will not move to a high rate modulation mode
even if the signal / interference environment will support high rate modes.
Maximum Transmit Power: The maximum Transmit Power the local wireless unit is
permitted to use to sustain a link.
Remote Transmit Maximum Power: The maximum transmit power the remote wireless unit
is permitted to use to sustain a link.
70

Transmit Power: Transmit power histogram
16
is expressed in dBm and presented as: max,
mean, min, and latest.
Receive Power: Receive power histogram is expressed in dBm and presented as: max,
mean, min, and latest.
Vector Error: The vector error measurement compares the received signal’s In phase /
Quadrature (IQ) modulation characteristics to an ideal signal to determine the composite error
vector magnitude. The results are stored in a histogram and expressed in dB and presented
as: max, mean, min and latest. The expected range for Vector Error would be approximately
0dB (NLOS link operating at sensitivity limit on BPSK ½) to –29dB (short LOS link running
64QAM 7/8).
Link Loss: The link loss is the total attenuation of the wireless signal between the two
point-to-point units.
16
All histograms are calculated over a one hour period. If the equipment has been running for
less than one hour then the histograms are calculated over the current elapsed time.

Receive Modulation Mode Detail: The receive modulation mode detail presents to the user
the reason why the wireless link is not operating at the maximum capacity (modulation mode).
Values that can be presented in this field are:
72
Page 75
•Running at maximum receive mode:
The wireless link is operating at its receive maximum capacity. To confirm that the
wireless link is operating at its maximum transmit capacity either look at the 'Transmit
Modulation Mode' on this page or look at the peer wireless units 'Receive Modulation
Mode Detail' attribute.
•Running at user-configured Target Modulation Mode:
This indicates that the wireless link could operate at a higher capacity but has been
limited in modulation mode by the user from the configuration page.
•Restricted because Installation is armed:
During installation the wireless link is restricted to operate in a low order modulation
mode (BPSK ½ ). Disarming the wireless units after installation will allow the wireless link
to adaptively select its own operational modulation mode.
•Restricted because of byte errors on the wireless link:
During normal operation the wireless link monitors its performance. If byte errors are
detected during normal data transmission / reception the wireless unit automatically
changes the active modulation mode to a more robust mode in order to reduce the
number of errors.
•Restricted because a DFS channel change is in progress:
During Spectrum Management (DFS) channel changes the wireless unit temporarily
reduces the modulation mode to BPSK ½.
•Restricted due to the low Ehthernet link speed:
If the Ethernet link speed is less that the instantaneous wireless link capacity then the
modulation mode is optimized so that the Ethernet link speed is satisfied using the most
robust modulation mode.
•Limited by the wireless conditions:
The wireless link capacity is limited by the current wireless conditions e.g. interference,
excess path loss, etc…

8.3.1 System Configuration Page
The configuration page (
400 Series Bridge.

Figure 29 - Configuration Page
While the majority of the system configuration is entered during installation and should never
require changing, this page offers the system administrator the ability to change the basic
system parameters for link, modulation and physical components.
Link Name: User defined identity for the unit (max 63 characters).
Link Location: Can be used to describe the location of the equipment or any other
equipment related notes (max 63 characters).
Master Slave Mode: The Master unit is the controlling unit with respect to the point-to-point
link and its maintenance. The master transmits until the link is made, while the Slave listens
for its peer and only transmits when the peer has been identified.
75
Page 78
Link Mode Optimization: By default, Link Mode Optimization of a point-to-point link is set to
‘IP Traffic’. In this configuration the wireless minimizes packet transmission errors by
automatically adapting the active modulation mode based on instantaneous vector error
measurements and the presence of codeword errors. This mode of operation is
recommended for connection oriented IP traffic protocols where packet loss is perceived by
the protocols as an indication of network congestion. It is recommended that when using this
mode of operation the ARQ state is set to ‘enabled’. The ‘TDM Traffic’ mode is recommended
for E1 / T1 applications and connectionless oriented protocols. In this mode the wireless link
is optimized for minimum transmission latency and preservation of data throughput by
allowing the link to maintain a higher modulation mode in the presence of a limited number of
codeword errors. It is recommended that when operating the link in TDM mode that the ARQ
state is set to disabled and that the Spectrum Management controls are used to fix the
wireless link to a single frequency. This can be achieved by using the installation wizard to
configure single frequency operation. In either case, a system reboot will be required.
Link Symmetry: By default Link Symmetry of a point-to-point link is ‘Symmetrical Data Rate
(1:1)’ in this configuration the ratio of time the wireless link spends transmitting and receiving
is equal. When Link Symmetry is configured to Asymmetric Data Rate (2:1) the wireless link
Master will spend twice as long transmitting as receiving. It should be noted that the data rate
available to the end users might not follow these ratios exactly. The exact data rates will be
dependant on the prevailing modulation modes.
Throughput Optimization: Throughput Optimization has two distinct modes:
• Data Throughputconfigures the wireless link for maximum data throughput.
• Low Latencyconfigures the wireless link to minimize packet latency during transmission
over the wireless link. When Low Latency mode is selected, the Link Symmetry is
automatically reconfigured to a symmetric link. Link asymmetry is not supported in Low
Latency mode.
Note: The “Throughput Optimization" option is not available on 4.9GHz variants.
ARQ State: Automatic Repeat reQuest (ARQ) is a mechanism where packets lost due to
transmission errors over the wireless link are retransmitted rapidly. The retransmission helps
to prevent TCP congestion mechanisms from inadvertently interpreting intermittent packet
loss as network congestion. ARQ must be enabled on both ends of the point-to-point link for it
to function.
76
Page 79
Target Receive Modulation Mode: This is the maximum mode the unit will use as its
adaptive modulation. The modulation modes available are:
• BPSK 1 / 2
• QPSK 1 / 2
• QPSK 2 / 3
• 16QAM 1 / 2
• 16QAM 3 / 4
• 64QAM 2 / 3
• 64QAM 3 / 4
• 64QAM 7 / 8
By default the Target Receive Modulation Mode is 64QAM 7/8. The value in brackets shows
the maximum unidirectional data for the current modulation / ranging mode combination.
Maximum Transmit Power: This specifies the maximum transmit power in dBm of the
system, it is country dependent and although the user can change this it will be limited to that
country’s regulations.
Ethernet Compression: When Ethernet compression is enabled all compressible Ethernet
packets are transmitted over the wireless link using a compressed data format. This will have
the net effect of increasing wireless link traffic throughput. Because the compression
techniques used in the PTP 400 Series Bridge are CPU intensive, compression is only
applied to modulation modes BPSK 1/2, QPSK 1/2 and QPSK 2/3. The net effect of
compression is solely dependant on the individual packet compressibility (entropy). Random
data will not produce good packet compression; however ASCII text and other non-random
data sources will produce an acceptable level of compressibility.
All the above attributes are non-volatile. Once set they will be used by the unit even after a
power-on reboot. A number of attributes, such as IP Address, Subnet Mask and Gateway IP
Address will require a reboot before they are used. If any of these attributes are changed a
reboot screen appears asking the user to verify the reboot. (See
Figure 30)

Ethernet Configuration: This enables the Ethernet configuration to be forced rather than
auto negotiated. The configuration should only be forced if you are having problems with auto
negotiation. You must ensure that you configure both this unit and the Ethernet port to which
it is connected identically. If you force a fixed Ethernet Configuration on the PTP 400 Series
Bridge, then you MUST also force the same fixed configuration on the equipment to which it
is connected. If you fail to force the configuration of the connected equipment, its automatic
configuration mechanisms will normally cause a duplex mismatch, and you will receive greatly
reduced throughput!

Receive Modulation Mode: Current active receive modulation mode.
Signal Strength Ratio: The Signal Strength Ratio, is the ratio of the power received by the
Vertical / Horizontal receivers.
Wireless Link Availability: Expresses the link availability as a percentage of time since the
first successful registration after a system restart. It is expressed as a percentage to four
decimal places.
Code Word Error Ratio: The ratio of detected codeword errors to the total number of
codewords since the last system counter reset.
PHY Code Word Error Counter: The wireless link uses error correction techniques to enable
reconstruction of packets where there is a certain level of data corruption. This counter
displays the total number of packets that were so badly corrupted that they could not be
reconstructed. See note
21.

The Detailed Counters Page provides:
Figure 40 - Detailed Counters
Ethernet Good Rx Packets: Total number of good Ethernet packets transmitted to the local
Ethernet interface. See note
21.
Ethernet Rx Fragments: Total number of short frames (<64 bytes, sometimes called runts)
received from the local Ethernet interface. On a half-duplex link, these packets are the result
of collisions and are to be expected. If you have forced the Ethernet configuration to full-
duplex and are getting such packets then you probably have a duplex mismatch (the device
you have connected to is running in half-duplex). See note
21.
Ethernet Bad FCS Rx Packets: Total number of Ethernet packets received from the local
Ethernet interface that contained an invalid Frame Check Sequence (checksum). See note
21.
Ethernet Invalid Rx Packets: Total number of invalid Ethernet packets received from the
local Ethernet interface See note
21.
Ethernet Good Tx Packets: Total number of good Ethernet packets transmitted to the local
Ethernet interface. See note
21.
Ethernet Dropped Tx Packets: Total number of Ethernet packets that were bridged to the
local unit but could not be transmitted because the local Ethernet link was down See note
21.
90
Page 93
Packets To Internal Stack: Total number of good packets the bridge has transmitted to the
internal TCP/IP stack. See note
21.
Packets From Internal Stack: Total number of good packets the bridge has received from
the internal TCP/IP stack. See note
21.
L2 Source MAC Address Conflicts: The number of times a packet received over the
wireless link had the Layer 2 (Ethernet) Source MAC Addresses of a device that had
previously been transmitting on the 'local' Ethernet network. This could indicate the presence
of a traffic loop or of L2 MAC Address spoofing on the network. See note
21.
Num ARQ Nacks Sent: Total number of ARQ requests sent.
Num ARQ Nacked Packets: Total number of ARQ Ethernet packets sent in reply to an ARQ
request.
ARQ Retransmitted Rx Packets: Total number of ARQ retransmitted packets that have
been received.
Statistics Page Refresh Period: Refresh the page at this rate
Wireless Good Rx Packets : Total number of good packets the bridge has received from the
wireless interface. See note
21.
Wireless Bad Rx Packets: Total number of corrupt packets the bridge has received from the
wireless interface See note
21.
Wireless Good Tx Packets: Total number of good packets the bridge has sent for
transmission by the wireless interface. See note
21.
Wireless Dropped Tx Packets: Total number of packets that the local unit could not bridge
to the remote unit because either the wireless link was down or because Ethernet packets are
being received faster than they can be transmitted over the wireless link. See note
21.
Wireless Rx Bytes: Total number of bytes that were received by the wireless interface. See
21.
note
Wireless Tx Bytes: Total number of bytes that were transmitted by the wireless interface.
See note
21.
Wireless Tx Compressible Bytes: Total number of bytes which the system has attempted to
compress - compression is dependant on modulation mode and packet size. See note
21.
Wireless Tx Compressed Bytes: Total number of compressed bytes sent by the wireless
interface. See note
21.
91
Page 94
Wireless Tx Uncompressed Bytes: Total number of 'compressible' bytes that were sent
uncompressed by the wireless interface because compression was inefficient. See note
Num ARQ Nacks Received: Total number of ARQ NACK packets received.
Num ARQ Nacked Packets Requested: Total number of NACKed packets requested to be
retransmitted by ARQ.
Num ARQ Nacked Packets Requeued: Total number of NACKed packets still available in
the ARQ buffer and successfully requeued by ARQ.

8.3.5 Install Wizard Pages
These pages are used during system installation. There follows a description of the install
pages along with their use during the installation configuration process. The actual installation
process is described in section
7.7.10 “Aligning the ODUs”.
All wireless links are shipped as paired units. They are pre-configured at the factory so that
they can be installed without the user supplying any configuration. Each wireless link is
shipped with a Quick Start Guide. Attached to the Quick Start Guide is a summary of the
default configuration data.
Table 11 shows a sample link configuration. The values highlighted
have been committed to the wireless units non-volatile storage.
Example PTP 400 Series Bridge Configuration Data

The factory default configuration is written to the ‘semi-permanent’ configuration bank.
WARNING: The factory default configuration is limited in range to 40 Km (25 miles). If you
wish to install a wireless link with a range of > 40 Km (> 25 miles) and < 200 Km (< 124 miles)
you must follow the ‘
Manually Configuring the Wireless Units’ in section 8.3.5.1.

8.3.5.1 Manually Configuring the Wireless Units
If the installer / system administrator wishes, they may modify the default installation
configuration. If only the IP addresses are incorrect it is recommended that the values are
changed via the configuration menu (Section
modification then it is recommended that the system administrator use the Installation Wizard.
The operational software for the PTP 400 Series Bridge requires a license key to enable the
wireless bridging capability and program region code specific parameters in to the unit.
Please refer to Section
8.3.18 for more information on how to enter and validate a license key
into the unit.

IP Address: Internet protocol (IP) address. This address is used by the family of Internet
protocols to uniquely identify this unit on a network.
Subnet Mask: A subnet allows the flow of network traffic between hosts to be segregated
based on a network configuration. By organizing hosts into logical groups, subnetting can
improve network security and performance.
Gateway IP Address: The IP address of a computer / router on the current network that acts
as a gateway. A gateway acts as an entrance / exit to packets from / to other networks.
Use VLAN Management Interface: This controls whether the management interfaces
(HTTP/SNMP/SMTP/SNTP) use a VLAN. Selecting this option first presents the user with the
warning box shown in
Figure 42, then presents the user with extra fields in which to enter the
Management VLAN ID, Priority and whether to validate the VLAN ID, as shown in
